  • How would I structure the loop to go through inputs?

    - by dmanexe
    I am attempting to make a loop that will go through an array structured like this: $input[n][checked] $input[n][input] The 2nd input acts as a price multiplier, but doesn't have to exist (field can be blank). I don't think a foreach loop is right because I don't think it handles the inputs from the form in the correct dimensional array order to keep the information together. I have inputs on a form that look like this: <input type="checkbox" name="measure[<?php echo $item->id; ?>][checked]" value="<?php echo $item->id; ?>"> <input class="item_mult" type="text" name="measure[<?php echo $item->id; ?>][input]" /> I am attempting to make the loop go through and act as a multiplier on the input relative to its sibling field. (i.e. input[1][input] would be an integer that I want to retrieve later, grouped with input[1][checked]) <? $field = $this->input->post('measure',true); $totals = array(); foreach($field as $value): if ($value['input'] == TRUE) { $query = $this->db->get_where('items', array('id' => $value['input']))->row(); $totals[] = $query->price; ?> <p><?=$query->name?> - <?=money_format('%(#10n', $query->price)?></p> <?php } else { } endforeach; ?> And finally, the last code to array_sum and print the grand total: <? $grand_total = array_sum($totals); ?> <p><?=money_format('%(#10n', $grand_total)?></p> Eventually, I will need to store these records in a database, so I am sending complete item IDs through, etc.

  • How do I reset a form in an ajax callback?

    - by B.Gordon
    I am sending a form using simple ajax and returning the results in a div above the form. The problem is that after the form is submitted and validated, I display a thank you and want to reset the form so they don't just press the submit button again... Can't seem to find the right code to do this... <form id="myForm" target="sendemail.php" method="post"> <div id="results"></div> <input type="text" name="value1"> <input type="text" name="value2"> <input type="submit" name="submit"> </form> So, my sendemail.php validation errors and success messages appear in #results without problems. But... when I try to send back a javascript form reset command, it does not work. Naturally I cannot see it in the source code since it is an AJAX callback so I don't know if that is the issue or if I am just using the wrong syntax. echo "<p>Thank you. Your message has been accepted for delivery.</p>"; echo "<script type=\"text/javascript\">setTimeout('document.getElementById('myForm').reset();',1000);</script>"; Any ideas gurus?

  • Programatically create web application & sub site

    - by Tejas
    I am using the following code to programatically create a web application & sub site, try { SPWebApplicationBuilder webAppBuilder = new SPWebApplicationBuilder(SPFarm.Local); SPWebApplication newApplication; int myPort = 3333; webAppBuilder.Port = myPort; //Port No. webAppBuilder.RootDirectory = new System.IO.DirectoryInfo("C:\\Inetpub\\wwwroot\\wss\\VirtualDirectories\\" + myPort); webAppBuilder.CreateNewDatabase = true; // Create new database webAppBuilder.DatabaseName = "WSS_Content_372772890a5a4a04abb460cd9ea3bd22"; // Database name webAppBuilder.DatabaseServer = webAppBuilder.DefaultZoneUri.Host; // DatabaseServer Host name/computer name webAppBuilder.UseNTLMExclusively = true; // Use NTLM authentication newApplication = webAppBuilder.Create(); // Create new web application newApplication.Provision(); // Provision it into web farm using (var mySiteCollection = newApplication.Sites.Add("/", "Site 3", "Site 3 Decscription", 1033, "STS#1", "In-Wai-Svr2\\Administrator", "Administrator", "[email protected]")) { using (var rootWeb = mySiteCollection.RootWeb) { // Code customizing root site goes here using (var subSite = rootWeb.Webs.Add("Site3.1", "Site 3.1", "Site 3.1 Description", 1033, "STS#1", true, false)) { // Code customizing sub site goes here } } } } catch(Exception ex) { ; } It works fine i.e. it creates the web application on the specified port with sub site but this sub site will not be shown under Sites menu of Quick launch bar also it will not be shown as a separate tab on the Home Page. Is it possible to do it programatically?

    Hi, I have a problem with a NSData writeToFile. I have implemented the code below but i have an anomaly.

  • Looping through recordset with VBA

    - by Robert
    I am trying to assign salespeople (rsSalespeople) to customers (rsCustomers) in a round-robin fashion in the following manner: Navigate to first Customer, assign the first SalesPerson to the Customer. Move to Next Customer. If rsSalesPersons is not at EOF, move to Next SalesPerson; if rsSalesPersons is at EOF, MoveFirst to loop back to the first SalesPerson. Assign this (current) SalesPerson to the (current) Customer. Repeat step 2 until rsCustomers is at EOF (EOF = True, i.e. End-Of-Recordset). It's been awhile since I dealt with VBA, so I'm a bit rusty, but here is what I have come up with, so far: Private Sub Command31_Click() 'On Error GoTo ErrHandler Dim intCustomer As Integer Dim intSalesperson As Integer Dim rsCustomers As DAO.Recordset Dim rsSalespeople As DAO.Recordset Dim strSQL As String strSQL = "SELECT CustomerID, SalespersonID FROM Customers WHERE SalespersonID Is Null" Set rsCustomers = CurrentDb.OpenRecordset(strSQL) strSQL = "SELECT SalespersonID FROM Salespeople" Set rsSalespeople = CurrentDb.OpenRecordset(strSQL) rsCustomers.MoveFirst rsSalespeople.MoveFirst Do While Not rsCustomers.EOF intCustomers = rsCustomers!CustomerID intSalesperson = rsSalespeople!SalespersonID strSQL = "UPDATE Customers SET SalespersonID = " & intSalesperson & " WHERE CustomerID = " & intCustomer DoCmd.RunSQL (strSQL) rsCustomers.MoveNext If Not rsSalespeople.EOF Then rsSalespeople.MoveNext Else rsSalespeople.MoveFirst End If Loop ExitHandler: Set rsCustomers = Nothing Set rsSalespeople = Nothing Exit Sub ErrHandler: MsgBox (Err.Description) Resume ExitHandler End Sub My tables are defined like so: Customers --CustomerID --Name --SalespersonID Salespeople --SalespersonID --Name With ten customers and 5 salespeople, my intended result would like like: CustomerID--Name--SalespersonID 1---A---1 2---B---2 3---C---3 4---D---4 5---E---5 6---F---1 7---G---2 8---H---3 9---I---4 10---J---5 The above code works for the intitial loop through the Salespeople recordset, but errors out when the end of the recordset is found. Regardless of the EOF, it appears it still tries to execute the rsSalespeople.MoveFirst command. Am I not checking for the rsSalespeople.EOF properly? Any ideas to get this code to work?

  • Auto populate a text field based on another text field

    - by Syed Aslam
    I am trying to auto-populate a text field based on the value of another input field. Currently trying to do this using observe_field helper like this: <%= observe_field( :account_name, :function => "alert('Name changed!')", :on => 'keyup' ) %> <% form_for(@account, :html => { :id => 'theform' }) do |f| %> <label for="accountname"> Account name </label> <%= form.text_field :name, :tabindex => '1' %> <label for="subdomain"> Subdomain </label> <%= form.text_field :subdomain, :tabindex => '2' %> <% end %> When the user enters text in the account_name text_field, I want to copy that convert into a subdomain (downcase and join by '-') and populate to subdomain text_field. But, in the process getting this error: element is null var method = element.tagName.toLowerCase(); protot...9227640 (line 3588) Where exactly am I going wrong here? Or is there a better way to do this?

  • If statement is ignored

    - by user2898120
    I am making a simple matchmaker as a learning project in JAVA. My program so far just asks a few questions, but I wanted to do gender specific questions, so I asked for their sex (m or f) and then attempted to add a message that only showed if sex was m. The dialog should say "well done, you are male!". Else it restarts method. Every time, no matter what I type it restarts the program. Here is my code: import javax.swing.JOptionPane; public class Main { public static void main(String[] args){ setVars(); } public static void setVars(){ String name = JOptionPane.showInputDialog(null, "What is your name?"); String sAge = JOptionPane.showInputDialog(null, "What is your age?"); String sex = JOptionPane.showInputDialog(null, "What is your sex?\n(Enter m or f)"); if (sex == "m"){ JOptionPane.showMessageDialog(null, "Well done, you are male.\nKeep Going!"); } int age = Integer.parseInt(sAge); String chars = JOptionPane.showInputDialog(null, "Name three charectaristics"); } }

  • Iterating Over Params Hash

    - by Joe Clark
    I'm having an extremely frustrating time getting some images to upload. They are obviously being uploaded as rack/multipart but the way that I'm iterating over my params hash must be causing the problem. I could REALLY use some help, so I can stop pulling out my hair. So I've got a params hash that looks like this: Parameters: {"commit"=>"Submit", "sighting_report"=>[{"number_seen"=>"1", "picture"=>#<File:/var/folders/IX/IXXrbzpCHkq68OuyY-yoI++++TI/-Tmp-/RackMultipart.85991.5>, "species_id"=>"2"}], "authenticity_token"=>"u0eN5MAfvGWtfEzrqBt4qfrL54VJ9SGX0jFLZCJ8iRM=", "sighting"=>{"sighting_date(2i)"=>"6", "name"=>"", "sighting_date(3i)"=>"5", "county"=>"0", "notes"=>"", "location"=>"", "sighting_date(1i)"=>"2010", "email"=>""}} My form can have multiple sighting reports with multiple pictures in each sighting report. Here's my controller code: def create_multiple @report = Report.new @report.name = params[:sighting]["name"] @report.sighting_date = Date.civil(params[:sighting][:"sighting_date(1i)"].to_i, params[:sighting][:"sighting_date(2i)"].to_i, params[:sighting][:"sighting_date(3i)"].to_i) @report.county_id = params[:sighting][:county] @report.location = params[:sighting][:location] @report.notes = params[:sighting][:notes] @report.email = params[:sighting][:email] @report.save! @report.reload for sr in params[:sighting_report] do sighting = SightingReport.new sighting.report_id = @report.id sighting.species_id = sr[:species_id] sighting.number_seen = sr[:number_seen] sighting.save if sr[:picture] sighting.reload for pic in sr[:picture] do p = SpeciesPic.new p.uploaded_picture = pic p.species_id = sighting.species_id p.report_id = @report.id p.save! end end end redirect_to :action => 'new_multiple' end

  • How to build a JSON response by combining @foo.to_json(options) and @bars.to_json(options) in Rails

    - by smotchkkiss
    First, the desired result I have User and Item models. I'd like to build a JSON response that looks like this: { "user": {"username":"Bob!","foo":"whatever","bar":"hello!"}, "items": [ {"id":1, "name":"one", "zim":"planet", "gir":"earth"}, {"id":2, "name":"two", "zim":"planet", "gir":"mars"} ] } However, my User and Item model have more attributes than just those. I found a way to get this to work, but beware, it's not pretty... Please help... My hacks home_controller.rb class HomeController < ApplicationController def observe respond_to do |format| format.js { render :json => Observation.new(current_user, @items).to_json } end end end observation.rb # NOTE: this is not a subclass of ActiveRecord::Base # this class just serves as a container to aggregate all "observable" objects class Observation attr_accessor :user, :items def initialize(user, items) self.user = user self.items = items end # The JSON needs to be decoded before it's sent to the `to_json` method in the home_controller otherwise the JSON will be escaped... # What a mess! def to_json { :user => ActiveSupport::JSON.decode(user.to_json(:only => :username, :methods => [:foo, :bar])), :items => ActiveSupport::JSON.decode(auctions.to_json(:only => [:id, :name], :methods => [:zim, :gir])) } end end

  • Adding a selection box into an ItemsControl?

    - by Jens
    I have a WPF ItemsControl with a Canvas ItemPanel. Drawing from an internal source, it displays lots of automatically generated Rectangles. As of now, it looks like this: <Window // .. NameSpaces > <Window.Resources> <DataTemplate x:Key="binTemplate"> <Rectangle x:Name="Rect" VerticalAlignment="Bottom" Canvas.Left="10" StrokeThickness="0"> // .. Databinding Height, Width, etc </Rectangle> </DataTemplate> </Window.Resources> <DockPanel x:Name="LayoutRoot" LastChildFill="True"> <ItemsControl ItemsSource="{Binding Bins}" ItemTemplate="{StaticResource binTemplate}"> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <Canvas MouseDown="Canvas_MouseDown" MouseMove="Canvas_MouseMove" MouseUp="Canvas_MouseUp"> <Rectangle x:Name="Selection" Canvas.Left="0" Canvas.Top="0" Visibility="Hidden" /> </Canvas> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> </DockPanel> </Window> I now try to implement a selection box, too.. well.. select my Rectangles. =) I tried just adding the box into the ItemsControl PanelTemplate, and controlling it with the Canvas mouse events, but it appears I am not allowed to do so. The error message is "Cannot explicitly modify Children collection of Panel used as ItemsPanel for ItemsControl. ItemsControl generates child elements for Panel." What is the preferred way to implement such behavior? I thought about overlaying another canvas (using negative Margin) and drawing the selection box in there, but that seems like a bad hack. Thanks in advance!

  • How do I populate these fields from existing data?

    - by dmanexe
    I'm not sure how to make a few parts of my form to populate from data from an array I'm passing from the database. First is this <select> object. The key estimate_lead_id in the database holds the value, and I want the dropdown to auto-select based on the value from the database. <select name="estimate_lead_id"> <? foreach($leads->result() as $lead) { ?> <option value="<?=$lead->id?>"><?=$lead->lead_name?></option> <? } ?> </select> Second (this is a little more complex), I have created a script that loops through and gets all of the items from each respective category. What I can't get it to do though is loop through these items and only display the items in the estimate, and then fill the fields with the respective values from the database. <?php foreach ($items['items_poolconcretedecking']->result() as $item) { ?> <input type="checkbox" name="measure[<?=$item->id?>][checkmark]" value="<?=$item->id?>"> <input class="item_mult" value="" type="text" name="measure[<?=$item->id?>][quantity]" /> <?php } ?>

  • Pattern/Matcher in Java?

    - by user1007059
    I have a certain text in Java, and I want to use pattern and matcher to extract something from it. This is my program: public String getItemsByType(String text, String start, String end) { String patternHolder; StringBuffer itemLines = new StringBuffer(); patternHolder = start + ".*" + end; Pattern pattern = Pattern.compile(patternHolder); Matcher matcher = pattern.matcher(text); while (matcher.find()) { itemLines.append(text.substring(matcher.start(), matcher.end()) + "\n"); } return itemLines.toString(); } This code works fully WHEN the searched text is on the same line, for instance: String text = "My name is John and I am 18 years Old"; getItemsByType(text, "My", "John"); immediately grabs the text "My name is John" out of the text. However, when my text looks like this: String text = "My name\nis John\nand I'm\n18 years\nold"; getItemsByType(text, "My", "John"); It doesn't grab anything, since "My" and "John" are on different lines. How do I solve this?

  • Rhino Mocks and ordered test with unordered calls

    - by Shaddix
    I'm using Rhino.Mocks for testing the system. I'm going to check the order of calling .LoadConfig and .Backup methods. I need .LoadConfig to be the first. Currently the code is like this: var module1 = mocks.Stub<IBackupModule>(); var module2 = mocks.Stub<IBackupModule>(); module1.Expect(x => x.Name).Return("test"); module2.Expect(x => x.Name).Return("test2"); using (mocks.Ordered()) { module1.Expect(x => x.LoadConfig(null)); module2.Expect(x => x.LoadConfig(null)); module1.Expect(x => x.Backup()); module2.Expect(x => x.Backup()); } mocks.ReplayAll(); The problem is, that there's also a call to .Name property, and i'm not interesting when it'll be called: before .LoadConfig or after the .Backup - it just doesn't matter. And when I run this I'm getting Exception: Unordered method call! The expected call is: 'Ordered: { IConfigLoader.LoadConfig(null); }' but was: 'IIdentification.get_Name();' Is there a way to deal with this? Thanks

  • How to query JDO persistent objects in unowned relationship model?

    - by Paul B
    Hello, I'm trying to migrate my app from PHP and RDBMS (MySQL) to Google App Engine and have a hard time figuring out data model and relationships in JDO. In my current app I use a lot of JOIN queries like: SELECT users.name, comments.comment FROM users, comments WHERE users.user_id = comments.user_id AND users.email = '[email protected]' As I understand, JOIN queries are not supported in this way so the only(?) way to store data is using unowned relationships and "foreign" keys. There is a documentation regarding that, but no useful examples. So far I have something like this: @PersistenceCapable public class Users {     @PrimaryKey     @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)     private Key key;     @Persistent     private String name;         @Persistent     private String email;         @Persistent     private Set<Key> commentKeys;     // Accessors... } @PersistenceCapable public class Comments {     @PrimaryKey     @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)     private Key key;     @Persistent     private String comment;         @Persistent     private Date commentDate;     @Persistent     private Key userKey;     // Accessors... } So, how do I get a list with commenter's name, comment and date in one query? I see how I probably could get away with 3 queries but that seems wrong and would create unnecessary overhead. Please, help me out with some code examples. -- Paul.

  • find and replace values in a flat-file using PHP

    - by peirix
    I'd think there was a question on this already, but I can't find one. Maybe the solution is too easy... Anyway, I have a flat-file and want to let the user change the values based on a name. I've already sorted out creating new name+value-pairs using the fopen('a') mode, using jQuery to send the AJAX call with newValue and newName. But say the content looks like this: host|http:www.stackoverflow.com folder|/questions/ folder2|/users/ And now I want to change the folder value. So I'll send in folder as oldName and /tags/ as newValue. What's the best way to overwrite the value? The order in the list doesn't matter, and the name will always be on the left, followed by a |(pipe), the value and then a new-line. My first thought was to read the list, store it in an array, search all the [0]'s for oldName, then change the [1] that belongs to it, and then write it back to a file. But I feel there is a better way around this? Any ideas? Maybe regex?

  • win32 console - form example!

    - by Bach
    I'm trying to build a simple form in a c++ win32 console application. instead of using cin and keep prompting the user to enter the details, i would like to display the form labels then using the tab key, allow the user to tab through. What is the simplest way of doing this, without having to use ncurses? all I need is cout the below all at once: Name: Username: Email: set the cursor position next to name Field, then each time you hit tab, i gotoxy, and set the cursor at the next position, then set the the cin to the next variable eg. at startup gotoxy(nameX, nameY); cin >> name; Hit Tab/enter gotoxy(usernameX, usernameY); cin >> username; Hit Tab/enter gotoxy(emailX, emailY); cin >> email; is this even doable? I tried while loops with, GetAsyncKeyState, and keyboard events, but the cin is not working properly in that loop. is there any good example for a super simple form, or reference for doing that? I know how to SetConsoleCursorPosition, but how to implement the tabbing while still being able to capture cin? thanks

The files copied over were: ASIHTTPRequestConfig.h ASIHTTPRequestDelegate.h ASIProgressDelegate.h ASIInputStream.h ASIInputStream.m ASIHTTPRequest.h ASIHTTPRequest.m ASIFormDataRequest.h ASIFormDataRequest.m My program is very basic: #import <Foundation/Foundation.h> int main (int argc, const char * argv[]) { NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; // Defining the various variables. char firstName[20]; char lastName[20]; char rank[5]; int leaveAccrued; int leaveRequested; // User Input. NSLog (@"Please input First Name:"); scanf("%s", &firstName); NSLog (@"Please input Last Name:"); scanf("%s", &lastName); NSLog (@"Please input Rank:"); scanf("%s", &rank); NSLog (@"Please input the number leave days you have accrued:"); scanf("%i", &leaveAccrued); NSLog (@"Please input the number of leave days you are requesting:"); scanf("%i", &leaveRequested); // Print results. NSLog (@"Name: %s %s", firstName, lastName); NSLog (@"Rank: %s", rank); NSLog (@"Leave Accrued: %i", leaveAccrued); NSLog (@"Leave Requested: %i", leaveRequested); [pool drain]; return 0; } How do I utilize the wrapper to export these 5 basic variables to a web server via an http request?

  • MySQL multidimensional arrays...

    - by jay
    What is the best way to store data that is dynamic in nature using MySQL? Let's say I have a table in which one item is "dynamic". For some entries I need to store one value, but for others it could be one hundred values. For example let's say I have the following simple table: CREATE TABLE manager ( name char(50), worker_1_name(50), worker_2_name(50), ... worker_N_name(50) ); Clearly, this is not an ideal way to set up a database. Because I have to accommodate the largest group that a manager could potentially have, I am wasting a lot of space in the database. What I would prefer is to have a table that I can use as a member of another table (like I would do in C++ through inheritance) that can be used by the "manager" table to handle the variable number of employees. It might look something like this. CREATE TABLE manager ( name char(50), underlings WORKERS ); CREATE TABLE WORKERS ( name char(50), ); I would like to be able to add a variable number of workers to each manager. Is this possible or am I constrained to enumerating all the possible number of employees even though I will use the full complement only rarely?

  • transactions and delete using fluent nhibernate

    - by Will I Am
    I am starting to play with (Fluent) nHibernate and I am wondering if someone can help with the following. I'm sure it's a total noob question. I want to do: delete from TABX where name = 'abc' where table TABX is defined as: ID int name varchar(32) ... I build the code based on internet samples: using (ITransaction transaction = session.BeginTransaction()) { IQuery query = session.CreateQuery("FROM TABX WHERE name = :uid") .SetString("uid", "abc"); session.Delete(query.List<Person>()[0]); transaction.Commit(); } but alas, it's generating two queries (one select and one delete). I want to do this in a single statement, as in my original SQL. What is the correct way of doing this? Also, I noticed that in most samples on the internet, people tend to always wrap all queries in transactions. Why is that? If I'm only running a single statement, that seems an overkill. Do people tend to just mindlessly cut and paste, or is there a reason beyond that? For example, in my query above, if I do manage it to get it from two queries down to one, i should be able to remove the begin/commit transaction, no? if it matters, I'm using PostgreSQL for experimenting.
