  • NoMethodError / undefined method `foobar_path' when using form_for

    - by user1850886
    I'm using form_for to create a chatroom and when I view the page I get the following error: NoMethodError in Chatrooms#new undefined method `chatrooms_path' for #<#<Class:0xa862b94>:0xa5307f0> Here's the code for the view, located in app/views/chatrooms/new.html.erb: <div class="center"> <%= form_for(@chatroom) do |f| %> <%=f.text_field :topic%> <br> <%=f.submit "Start a discussion", class: "btn btn-large btn-primary"%> <% end %> </div> Here's the relevant controller: class ChatroomsController < ApplicationController def new @chatroom = Chatroom.new end def show @chatroom = Chatroom.find(params[:id]) end end If I change the line <%= form_for(@chatroom) do |f| %> to <%= form_for(:chatroom) do |f| %> it works fine. I've searched around for similar questions but none of the solutions have worked for me. Help?

  • Can't use method from class in other file

    - by user1833848
    I am not able to use one of my methods that i implemented in my tableviewcell file in my tableview controller implementation. I tried searching the web and xcode help with no luck. My codes looks like this: TableViewController.h: #import TableViewCell.h @interface TableViewController : UITableViewController @property (nonatomic, strong) IBOutlet UIBarButtonItem *A1Buy; @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender; TableViewController.m: @implementation A1ViewController @synthesize A1Buy = _A1Buy; @synthesize userInteractionEnabled; - (IBAction)A1Buy:(UIBarButtonItem *)sender { [TableViewCell Enable]; //this is where it gives an error } TableViewCell.h: @interface TableViewCell : UITableViewCell { BOOL Enable; BOOL Disable; } @property (nonatomic, getter = isUserInteractionEnabled) BOOL userInteractionEnabled; TableViewCell.m: @implementation TableViewCell; @synthesize userInteractionEnabled; - (BOOL) Enable { return userInteractionEnabled = YES; } - (BOOL) Disable { return userInteractionEnabled = NO; } As you can see i am trying to enable user interaction with a button, but Xcode only gives me errors like "class does not have this method" and stuff like that. All files are importet correctly so thats not why. Would appreciate any help. Thanks!

  • Pull To Refresh on iphone not working as expected

    - by Kleemann
    I have been using this: http://blog.leahculver.com/2010/12/iphone-pull-to-refresh.html to make the pull to refresh function in my app. But I cant see the text "Pull down to refresh...", "Release to refresh..." and "Loading...". All I've done is copy the files into my project, link against QuartzCore framework, and changed the .h file of my view controller so it is a subclass of PullRefreshTableViewController. Then I added the refresh method. Is seems that the initWithStyle method in PullRefreshTableViewController never is executed. But i should be, in my tableViewcellForRowAtIndexPath. - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"CellIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } cell.textLabel.text = @"Text"; return cell; } The initWithStyle method from the PullRefreshTableViewController.m: - (id)initWithStyle:(UITableViewStyle)style { self = [super initWithStyle:style]; if (self != nil) { textPull = [[NSString alloc] initWithString:@"Pull down to refresh..."]; textRelease = [[NSString alloc] initWithString:@"Release to refresh..."]; textLoading = [[NSString alloc] initWithString:@"Loading..."]; NSLog(@"in"); } NSLog(@"out"); return self; } The logs are never printed in the console I really cant see where the problem is ?

  • Magento - save quote_address on cart addAction using observer

    - by Byron
    I am writing a custom Magento module that gives rate quotes (based on an external API) on the product page. After I get the response on the product page, it adds some of the info from the response into the product view's form. The goal is to save the address (as well as some other things, but those can be in the session for now). The address needs to be saved to the quote, so that the checkout (onestepcheckout, free version) will automatically fill those values in (city, state, zip, country, shipping method [of which there are 3]) and load the rate quote via ajax (which it's already doing). I have gone about this by using an Observer, and watching for the cart events. I fill in the address and save it. When I end up on the cart page or checkout page ~4/5 times the data is lost, and the sql table shows that the quote_address is getting save with no address info, even though there is an explicit save. The observer method's I've used are: checkout_cart_update_item_complete checkout_cart_product_add_after The code saving is: (I've tried this with the address, quote and cart all not calling save() with the same results, as well as not calling setQuote() $quote->getShippingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->getBillingAddress() ->setCountryId($params['estimate_to_country']) ->setCity($params['estimate_to_city']) ->setPostcode($params['estimate_to_zip_code']) ->setRegionId($params['estimate_to_state_code']) ->setRegion($params['estimate_to_state']) ->setCollectShippingRates(true) ->setShippingMethod($params['carrier_method']) ->setQuote($quote) ->save(); $quote->save(); $cart->save(); I imagine there's a good chance this is not the best place to save this info, but I am not quite sure. I was wondering if there is a good place to do this without overriding a whole controller to save the address on the add to cart action. Thanks so much, let me know if I need to clarify

  • OpenLayers eraseFeatures doesn't erase features from map screen.

    - by Jenny
    I'm using OpenLayers, and have a layer for my Map, and a single Vector Layer. In this vector layer, I am using the DrawFeature control to draw a square. I have a listener waiting for a feature to be added, and then deleting any existing features (I only want one square at a time), like so: polygonLayer.events.register("beforefeatureadded", feature, function(evt){ console.log("Clearing existing polygons"); console.log(polygonLayer.features.length); polygonLayer.destroyFeatures(); polygonLayer.redraw(); });//end attempt at events registration When I check my layer.features.size, I can see that it's always 1, just like I expect, but the squares on the screen are still displayed. Even when I call .redraw() on the layer, the squares are still there. Is there some extra step I'm missing? Edit: You can find my code here: http://pastie.org/909644 Edit: Just realized: If I draw a square from previously existing coordinates, I can clear it just fine. It seems to be just the squares drawn from the controller that are an issue?

  • Rails: Duplicate functionality across controllers? A humble plea.

    - by Alex
    So I'm working with authlogic, and I'm trying to duplicate the login functionality to the welcome page, so that you can log in by restful url or by just going to the main page. No, I don't know if we'll keep that feature, but I want to test it out anyway. Here's the error message: RuntimeError in Welcome#index Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id The code is below. Basically, what's happening is the index view (the first code snippet) is sending the information from the form to the create method of user_sessions controller. At this point, in theory, it create should just pick up, but it doesn't. PLEASE help. Please. I've been doing this for about 8 hours. I checked Google. I checked IRC. I checked every book I could find. You don't even have to answer, I can to the grunt work if you just point me in the right direction. <% form_for @user_session, :url => user_sessions_path do |f| %> <%= f.text_field :email %><br /> <%= f.password_field :password %> <%= submit_tag 'Login' %> <% end %> class ApplicationController < ActionController::Base helper :all # include all helpers, all the time protect_from_forgery # See ActionController::RequestForgeryProtection for details # Scrub sensitive parameters from your log # filter_parameter_logging :password helper_method :current_user_session, :current_user before_filter :new_session_object protected def new_session_object unless current_user @user_session = UserSession.new(params[:user_session]) end end private def current_user_session return @current_user_session if defined?(@current_user_session) @current_user_session = UserSession.find end def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end

  • How to handle exceptions from an image-generating Servlet?

    - by ssahmed555
    I have a simple (Servlet, JSP, and JSTL) web app whose main functionality is displaying images retrieved from a back-end server. The controller servlet forwards the user to a JSP that in turn uses another Servlet to display the resulting image on that same JSP. Further down, the JSP has a line similar to: <a href="<c:out value='${imageURL}'/>"><img src="<c:out value='${imageURL}'/>" alt="image view" border="1"></a> which invokes a GET request on the image-generating servlet causing it to generate the image. My question is: how do I handle Exceptions thrown by this image-generating servlet? I already have an error page defined (in web.xml) to handle ServletException within my web app but this doesn't work for this image-generating Servlet, and results in the following errors showing up in my Tomcat server logs: SEVERE: Exception Processing ErrorPage[exceptionType=javax.servlet.ServletException, location=/WEB-INF/ExceptionPage.jsp] java.lang.IllegalStateException: Cannot reset buffer after response has been committed What's my recourse in this situation? I'd like to be able to handle Exceptions thrown from this image-generating Servlet, and display some error on the main UI or forward the user to another error page.

  • NSMagedObjectContext, threads and NSFechedResultsController

    - by tmpz
    Dear iphone developers, Core Data newbie speaking here. In my application I have two NSManagedObjectContext that refer to that same NSPersistentStorageController. One ManagedObjectContext (c1) is in the main thread --created when I create a NSFetchedResultsController -- and the second ManagedObjectContext (c2) created in a second thread, running in the background, detached from the main thread. In the background thread I pull some data off a website and insert the entities created for the pulled data in the thread's ManagedObjectContext (c2). In the meanwhile, the main thread sits doing nothing and displaying a UITableView whose data do be display should be provided by the NSFetchedResultsController. When the background thread has finished pulling the data and inserting entities in c2, c2 saves, and the background thread notifies the main thread that the processing has finished before it exiting. As a matter of fact, the entities that I have inserted in c2 are know by c1 because it can ask it about one particular entity with [c1 existingObjectWithID:ObjectID error:&error]; I would expect at this point, if I call on my tableview reloadData to see some rows showing up with the data I pulled from the web in the background thread thanks to the NSFetchedResults controller which should react to the modifications of its ManagedObjectContext (c1). But nothing is happening! Only if I restart the application I see what I have previously pulled from the web! Where am I doing things wrong? Thank you in advance!

  • What is the mean of @ModelAttribute annotation at method argument level?

    - by beemaster
    Spring 3 reference teaches us: When you place it on a method parameter, @ModelAttribute maps a model attribute to the specific, annotated method parameter I don't understand this magic spell, because i sure that model object's alias (key value if using ModelMap as return type) passed to the View after executing of the request handler method. Therefore when request handler method executes the model object's name can't be mapped to the method parameter. To solve this contradiction i went to stackoverflow and found this detailed example. The author of example said: // The "personAttribute" model has been passed to the controller from the JSP It seems, he is charmed by Spring reference... To dispel the charms i deployed his sample app in my environment and cruelly cut @ModelAttribute annotation from method MainController.saveEdit. As result the application works without any changes! So i conclude: the @ModelAttribute annotation is not needed to pass web form's field values to the argument's fields. Then i stuck to the question: what is the mean of @ModelAttribute annotation? If the only mean is to set alias for model object in View, then why this way better than explicitly adding of object to ModelMap?

  • Calling a register method from 2 or more controllers best practice

    - by PussInBoots
    I don't want to repeat myself. That is, I don't want the same code in two different controllers. I always start from a default mvc5 web app project. That project has a Register ActionMethod in an AccountController: // // GET: /Account/Register [AllowAnonymous] public ActionResult Register() { return View(); } // // POST: /Account/Register [HttpPost] [AllowAnonymous] [ValidateAntiForgeryToken] public async Task<ActionResult> Register(RegisterViewModel model) { if (ModelState.IsValid) { var user = new ApplicationUser() { UserName = model.UserName }; var result = await UserManager.CreateAsync(user, model.Password); if (result.Succeeded) { await SignInAsync(user, isPersistent: false); return RedirectToAction("Index", "Home"); } else { AddErrors(result); } } // If we got this far, something failed, redisplay form return View(model); } Say I have a CampaignController and I want to register a user when he/she is on that page, fills out his/her username and pass and clicks the send form/submit button. What is the best thing to do in the ActionMethod of that form/controller? Yes, I want to have the registerform in two or more places. What is the best way to accomplish this in mvc 5?

  • Get notified when UITableView has finished asking for data?

    - by kennethmac2000
    Hi everyone, Is there some way to find out when a UITableView has finished asking for data from its data source? None of the viewDidLoad/viewWillAppear/viewDidAppear methods of the associated view controller (UITableViewController) are of use here, as they all fire too early. None of them (entirely understandably) guarantee that queries to the data source have finished for the time being (eg, until the view is scrolled). One workaround I have found is to call reloadData in viewDidAppear, since, when reloadData returns, the table view is guaranteed to have finished querying the data source as much as it needs to for the time being. However, this seems rather nasty, as I assume it is causing the data source to be asked for the same information twice (once automatically, and once because of the reloadData call) when it is first loaded. The reason I want to do this at all is that I want to preserve the scroll position of the UITableView - but right down to the pixel level, not just to the nearest row. When restoring the scroll position (using scrollRectToVisible:animated:), I need the table view to already have sufficient data in it, or else the scrollRectToVisible:animated: method call does nothing (which is what happens if you place the call on its own in any of viewDidLoad, viewWillAppear or viewDidAppear). Thanks in advance for your assistance!

  • Replacing one image with another image through ajax makes it dissappear for a split second

    - by ooo
    I have the following code (asp.net-mvc, jquery) (i have simplified the example to show the issue) where i want to click on an image and have it replaced with another image. This works fine but the first time i click it, the original image disappears (for a split second) before the other image shows up. After that it works seamlessly. Is there any way to eliminate this quirk so there is not split second where no image is shown? Here is my controller code: public ActionResult UpdateFavoriteExercise(int id, string toggle) { if (toggle == "off") { return Content("<img toggle='off' src='/images/vote-favorite-off1.png' border=0'>"); } return Content("<img toggle='on' src='/images/vote-favorite-on1.png' border=0'>"); } Here is my jquery code: $('div.favoriteExercise').live('click', function() { var id = $(this).attr("id"); var toggle = $(this).attr("toggle"); if (toggle == 'off') { onOff = 'on'; } else { onOff = 'off'; } var url = '/Tracker/UpdateFavoriteExercise/' + id + '?toggle=' + onOff; $(this).load(url); $(this).attr("toggle", onOff); });

  • "render as JSON" is display JSON as text instead of returning it to AJAX call as expected

    - by typoknig
    I'm navigating to the index action of MyController. Some of the on the index page I'm making an AJAX call back to myAction in MyController. I expect myAction action to return some data as JSON to my AJAX call so I can do something with the data client side, but instead of returning the data as JSON like I want, the data is being displayed as text. Example of my Grails controller: class MyController { def index() { render( view: "myView" ) } def myAction { def mapOfStuff = [ "foo": "foo", "bar":] render mapOfStuff as JSON } } Example of my JavaScript: $( function() { function callMyAction() { $.ajax({ dataType: 'json', url: base_url + '/myController/myAction', success: function( data ) { $(function() { if( data.foo ) { alert( data.foo ); } if( data.bar ) { alert( data.bar ); } }); } }); } }); What I expect is that my page will render, then my JavaScript will be called, then two alerts will display. Instead the JSON array is displayed as text in my browser window: {"foo":"foo","bar":"bar"} At this point the last segment of the URL in my address bar is myAction and not index. Now if I manually enter the URL of the index page and press refresh, all works as expected. I have half a dozen AJAX calls I do the exact same way and none of them are having problems. What is the deal here? UPDATE: I have noticed something. When I set a break point in the index action of MyController and another one in the myAction action, the break point in myAction gets hit BEFORE the break point in index, even though I am navigating to the index. This is obviously closer to the root cause of my problem, but why is it happening?

  • Can you target Google Chrome? (Yes, you can)

    - by Kyle Sevenoaks
    Hi, I need to position this update button on www.euroworker.no/order (you'll have to add an item to the cart, use the Kjøp button to add and Handlevogn to view the cart). Works in FF and IE. (Although there is another alignment problems with IE) but not in Chrome or Safari. I had it working before, but the only thing I can think of to do is target safari and Chrome. Is this possible? Here's the CSS and HTML(Smarty) for you. HTML(Smarty): {capture assign="cartUpdate"} <div id="cartUpdate"><!--<input type="submit" class="submit" value="{tn _update}" />--> <button type="submit" class="submit" id="oppdatersubmit" name="saveFields" title="Oppdater" value="">&nbsp;</button> </div> {/capture} {assign var="cartUpdate" value=$cartUpdate|@str_split:10000} {php}$GLOBALS['cartUpdate'] = $this->get_template_vars('cartUpdate'); $this->assign_by_ref('GLOBALS', $GLOBALS);{/php} {form action="controller=order action=update" method="POST" enctype="multipart/form-data" handle=$form id="cartItems"} CONTENT {/form} And the CSS: #oppdatersubmit { background-image:url(../../upload/oppdater.png); background-repeat:no-repeat; background-position:left; background-color:none; border:none; overflow:hidden; outline:none; white-space: nowrap; width:77px; height:25px; cursor:pointer; position:absolute; } #cartUpdate { position:absolute; width:160px; height:30px; left:580px; bottom:130px; } Need to change these for Chrome and Safari.

  • Pass Element value to $ajax->link in cakephp

    - by TwoThumbs
    I need to pass the value of an element to an $ajax-link without using a form/submit structure. (because I have a dynamically set number of clickable links through which I am triggering the action) I used to do this in Ruby using the Prototype javascript function $F like this: <%= link_to_remote "#{item.to_s}", :url => { :action => :add_mpc }, :with => "'category=' + $F('mpc_category')" -%> But this does not seem to work in Cakephp: <?php echo $ajax->link(substr($vehicle['vehicles']['year'], -2), array('action' => 'add_mpc', 'category' => '$F("mpc_category")'), array('update' => 'results', 'position' => 'top')); ?> PHP sees $F as a variable instead of a call to javascript. I'm not too familiar with Javascript, but is there another way to pass the value of the 'mpc_category' input element to the controller through this link? I have been looking for a couple days and can't find anyone dealing with this specific issue. Thanks for any assistance. Edit: fixed syntax in php statement.

  • Additional information in ASP.Net MVC View

    - by Max Malmgren
    I am attempting to implement a custom locale service in an MVC 2 webpage. I have an interface IResourceDictionary that provides a couple of methods for accessing resources by culture. This is because I want to avoid the static classes of .Net resources. The problem is accessing the chosen IResourceDictionary from the views. I have contemplated using the ViewDataDictionary given, creating a base controller from which all my controllers inherits that adds my IResourceDictionary to the ViewData before each action executes. Then I could call my resource dictionary this way: (ViewData["Resources"] as IResourceDictionary).GetEntry(params); Admittedly, this is extremely verbose and ugly, especially in inline code as we are encouraged to use in MVC. Right now I am leaning towards static class access ResourceDictionary.GetEntry(params); because it is slightly more elegant. I also thought about adding it to my typed model for each page, which seems more robust than adding it to the ViewData.. What is the preferred way to access my ResourceDictionary from the views? All my views will be using this dictionary.

  • Not getting an array as result (calling a webservice by AJAX-JSON)

    - by Pasargad
    I'm trying to get the result of my web service as an array and then loop over the result to fetch all of the data; what I have done so far: In my web service when I return the result I use return json_encode($newFiles); and the result is as following: "[{\"path\":\"c:\\\\my_images\\\\123.jpg\",\"ID\":\"123\",\"FName\":\"John\",\"LName\":\"Brown\",\"dept\":\"Hr\"}]" tehn in my Web application I'm calling the rest web service by the following code in the RestService class: public function getNewImages($time) { $url = $this->rest_url['MyService'] .

  • implementing user tracking (logging) in Rails 3

    - by seth.vargo
    Hi, I'm creating a Rails application in which logging individual user actions is vital. Every time a user clicks a url, I want to log the action along with all parameters. Here is my current implementation: class CreateActivityLogs < ActiveRecord::Migration create_table :activity_logs do |t| t.references :user t.string :ip_address t.string :referring_url t.string :current_url t.text :params t.text :action t.timestamps end end   class ActivityLog < ActiveRecord::Base belongs_to :user end In a controller, I'd like to be able to do something like the following: ... ActivityLog::log @user.id, params, 'did foo with bar' ... I'd like to have the ActivityLog::log method automatically get the IP address, referring url, and current url (I know how to do this already) and create a new record in the table. So, my questions are: How do I do this? How do I use ActivityLog without having to create an instance everytime I want to log? Is this the best way? Some people have argued for a flat-file log for this kind of logging - however, I want admins to be able to see a user's activity in the backend as well, so I thought a database solution may be better?

  • two view controllers and reusability with delegate

    - by netcharmer
    Newbie question about design patterns in objC. I'm writing a functionality for my iphone app which I plan to use in other apps too. The functionality is written over two classes - Viewcontroller1 and Viewcontroller2. Viewcontroller1 is the root view of a navigation controller and it can push Viewcontroller2. Rest of the app will use only ViewController1 and will never access Viewcontroller2 directly. However, triggered by user events, Viewcontroller2 has to send a message to the rest of the app. My question is what is the best way of achieving it? Currently, I use two level of delegation to send the message out from Viewcontroller2. First send it to Viewcontroller1 and then let Viewcontroller1 send it to rest of the app or the application delegate. So my code looks like - //Viewcontroller1.h @protocol bellDelegate -(int)bellRang:(int)size; @end @interface Viewcontroller1 : UITableViewController <dummydelegate> { id <bellDelegate> delegate; @end //Viewcontroller1.m @implementation Viewcontroller1 -(void)viewDidLoad { //some stuff here Viewcontroller2 *vc2 = [[Viewcontroller2 alloc] init]; vc2.delegate = self; [self.navigationController pushViewController:vc2 animated:YES]; } -(int)dummyBell:(int)size { return([self.delegate bellRang:size]); } //Viewcontroller2.h @protocol dummyDelegate -(int)dummyBell:(int)size; @end @interface Viewcontroller2 : UITableViewController { id <dummyDelegate> delegate; @end //Viewcontroller2.m @implementation Viewcontroller2 -(int)eventFoo:(int)size { rval = [self.delegate dummyBell:size]; } @end

    I have a url http://*.com/branch/module/view/id/1/cat/2/etc/3. It becomes. array ( 'module'=>'branch', 'controller'=>'module', 'action'=>'view' ); next I need to get the params. Ihave this array. /*function getNextSegments($n,$segments) { return array_slice ( $q = $this->segments, $n + 1 ); } $params = getNextSegments(3); */ array ( 0 => 'id', 1 => '1', 2 => 'cat', 3 => '2', 4 => 'etc', 5 => '3' );//params And i wanna convert it to this one: array ( 'id'=1, 'cat'=2, 'etc'=3, ); How i can do this using php function. I know I can do using for or foreach, but I think php has such function , but i cant find it :(. Thank you. class A { protected function combine($params) { $count = count ( $params ); $returnArray = array (); for($i = 0; $i < $count; $i += 2) { $g = $i % 2; if ($g == 0 or $g > 0) { if (isset ( $params [$i] ) and isset ( $params [$i + 1] )) $returnArray [$params [$i]] = $params [$i + 1]; } } return $returnArray; } } This works normaly. If anybody has better login for this please help. Thank you again.

  • How can I get a default value in some instances but not others?

    - by Connor Wagner
    I am making an iPhone app and want to use an 'if' statement and a boolean to set default values in some instances but not others... is this possible? Are there alternative options if it is not possible? In the MainViewController.m I have: @interface MainViewController (){ BOOL moveOver; } [...] - (void)viewDidLoad { [super viewDidLoad]; _label.text = [NSString stringWithFormat:@"%i", computerSpeed]; } } [...] - (void)flipsideViewControllerDidFinish:(FlipsideViewController *)controller { [self dismissViewControllerAnimated:YES completion:nil]; moveOver = true; } The problem that it is redefined when the ViewDidLoad runs... I need a statement that will not redefine when the ViewDidLoad runs. I have something that I feel like is much closer to working... In the ViewDidLoad I have: if (playToInt != 10 || computerMoveSpeed != 3) { moveOver = TRUE; } which connects to my created method, gameLoop. It has if (moveOver == false) { computerMoveSpeed = 3; playToInt = 10; } I have tried putting the code in the gameLoop into the ViewDidLoad, but it had the same effect. When moveOver was false, the computerMoveSpeed and the playToInt were both seemingly 0. I have two UITextFields and typed 10 and 3 in them... does this not set it to the default? It seems to set the default to 0 for both, how do I change this? THIS IS A DIFFERENT ISSUE THAN THE THREE BOOLEAN VALUES QUESTION

  • How to add sub category on my codeigniter php application ?

    - by sagarmatha
    Hello friends I have a view echo "<label for='parent'>Category</label><br/> "; echo form_dropdown('category_id', $categories). "<p>"; controller function create(){ if($this->input->post('name')){ $this->MProducts->addProduct(); $this->session->set_flashdata('message', 'Products Created'); redirect('admin/products/index', 'refresh'); }else{ $data['title'] = "Create Product"; $data['main'] = 'admin_product_create'; $data['categories']= $this->MCats->getTopCategories(); $this->load->vars($data); $this->load->view('dashboard'); } } and the model is function getTopcategories(){ $data = array(); $data[0] = 'root'; $this->db->where('parentid',0); $Q = $this->db->get('categories'); if($Q->num_rows() > 0){ foreach($Q->result_array() as $row){ $data[$row['id']] = $row['name']; } } $Q->free_result(); return $data; } Basically, what i want is we get sub categories when we click categories and 'selected' subcategory id goes to database when we create products, So that we can list products by sub categories. Please help me how do we do that ?
