  • Is there anyway to carry a value in php forward to a second page?

    - by Henry Aspden
    I have created a php site, and previously it was listing only products with defined values. I have now changed it to include an array of products for example all products WHERE id = "spotlights" and this works great so it means I can add new products just to the database, but I still have to add the second page manually. e.g going from the product div on the main page, through to www.example.com/spotlight_1.php Is there anyway in PHP to carry the data from my index.php e.g. the ID through to the next page? so that I can have a template product.php page, and I can use a database pull to echo the product information required. So on index.php i click on the product with ID="1" and on the product.php page, it loads the relevant data for product 1. I can write the php SQL/mySQL calls myself, its just the way to carry accross a value from the previous page which I dont understand Regards Henry p.s. all the IDs and things are stored in the database already as 1 to 3digit values e.g. 3 or or 93 or 254 Any advice as always is greatly appreciated Regards Henry

  • Send email in wordpress

    - by jul
    hi, I'm trying to send an email using PHP mail() in a wordpress site. I created an empty page http://www.exam-vision.com/request-flip-up-instructions which template includes the php code shown below. When I post the data, isset($_REQUEST['email']) is false, while I can in firebug that the data have been posted correctly. What can be wrong? thanks <?php if (isset($_REQUEST['email'])) //if "email" is filled out, send email { //send email $email = $_REQUEST['email'] ; $subject = $_REQUEST['subject'] ; $message = $_REQUEST['message'] ; mail( "<someemail>", "Subject: $subject", $message, "From: $email" ); echo "Thank you for using our mail form"; } else //if "email" is not filled out, display the form { echo "<form method='post' action='http://www.exam-vision.com/request-flip-up-instructions'> Email: <input name='email' type='text' /><br /> Subject: <input name='subject' type='text' /><br /> Message:<br /> <textarea name='message' rows='15' cols='40'> </textarea><br /> <input type='submit' /> </form>"; } ?>

    - by kimera84
    Hi Everyone, I'm new in blackberry environement programming, I'm developing an application for this device and there are some probs about libraries that I don't understand. I have the main project called: npoBBerry - his library is NET_RIM_BLACKBERRY (from 4.6.1 version...) it includes other two projects: Npo - his library is standard jre6 (Npo inlcudes NpoCore) NpoCore - his library is standard jre6 Compliance was set... In Java Compiler level is set to 1.4 for all. Now the problem is that I'm not able to build my project. 4 errors: Error preverifying class ch.yek.npo.model.Advertising Error preverifying class ch.yek.npo.repository.Repository$1 Error!: Error: preverifier failed: C:\Program Files\eclipse\plugins\net.rim.eide.componentpack4.6.1_4.6.1.27\components\bin\preverify.ex ...

  • MVC 4 Beta with Mobile Project FIle Upload does not work

    - by Jim Shaffer
    I am playing around with the new MVC 4 beta release. I created a new web project using the Mobile Application template. I simply added a controller and a view to upload a file, but the file is always null in the action result. Is this a bug, or am I doing something wrong? Controller Code: using System.IO; using System.Web; using System.Web.Mvc; namespace MobileWebExample.Controllers { public class FileUploadController : Controller { public ActionResult Index() { return View(); } [AllowAnonymous] [HttpPost] [AcceptVerbs(HttpVerbs.Post)] public ActionResult Upload(HttpPostedFileBase file) { int i = Request.Files.Count; if (file != null) { if (file.ContentLength > 0) { var fileName = Path.GetFileName(file.FileName); var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName); file.SaveAs(path); } } return RedirectToAction("Index"); } } } And the view looks like this: @{ ViewBag.Title = "Index"; } <h2>Index</h2> <form action="@Url.Action("Upload")" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="file" id="file" /> <input type="submit" value="Submit" /> </form>

  • Can an interface define the signature of a c#-constructor

    - by happyclicker
    I have a .net-app that provides a mechanism to extend the app with plugins. Each plugin must implement a plugin-interface and must provide furthermore a constructor that receives one parameter (a resource context). During the instantiation of the plugin-class I look via reflection, if the needed constructor exists and if yes, I instantiate the class (via Reflection). If the constructor does not exists, I throw an exception that says that the plugin not could be created, because the desired constructor is not available. My question is, if there is a way to declare the signature of a constructor in the plugin-interface so that everyone that implements the plugin-interface must also provide a constructor with the desired signature. This would ease the creation of plugins. I don’t think that such a possibility exists because I think such a feature falls not in the main purpose for what interfaces were designed for but perhaps someone knows a statement that does this, something like: public interface IPlugin { ctor(IResourceContext resourceContext); int AnotherPluginFunction(); } I want to add that I don't want to change the constructor to be parameterless and then set the resource-context through a property, because this will make the creation of plugins much more complicated. The persons that write plugins are not persons with deep programming experience. The plugins are used to calculate statistical data that will be visualized by the app.

  • Constructor is being invoked twice

    - by Knowing me knowing you
    In code: LINT a = "12"; LINT b = 3; a = "3";//WHY THIS LINE INVOKES CTOR? std::string t = "1"; //LINT a = t;//Err NO SUITABLE CONV FROM STRING TO LINT. Shouldn't ctor do it? #pragma once #include "LINT_rep.h" class LINT { private: typedef LINT_rep value_type; const value_type* my_data_; template<class T> void init_(const T&); public: LINT(const char* = 0); LINT(const std::string&); LINT(const LINT&); LINT(const long_long&); LINT& operator=(const LINT&); virtual ~LINT(void); LINT operator+()const; //DONE LINT operator+(const LINT&)const;//DONE LINT operator-()const; //DONE LINT operator-(const LINT&)const;//DONE LINT operator*(const LINT&)const;//DONE LINT operator/(const LINT&)const;///WAITS FOR APPROVAL LINT& operator+=(const LINT&);//DONE LINT& operator-=(const LINT&);//DONE LINT& operator*=(const LINT&);//DONE LINT operator/=(const LINT&);///WAITS FOR APPROVAL }; in line number 3 instead of assignment optor ctor is invoked. Why? I'm willing to uppload entire solution on some server otherwise it's hard to put everything in here. I can also upload video file. Another thing is that when I implement this assignment optor I'm getting an error that this optor is already in obj file? What's going on?

  • WPF Style: how to change GradientStop Color in Trigger

    - by Nike
    I have a Button Style: <Style x:Key="ButtonStyle1" TargetType="{x:Type Button}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Button}"> <Grid> <Path x:Name="path1" ...

How can i get an access to Color Property in Trigger? I tried TargetName="path1.gs1" but it doesn't work. Any idea?

  • Book recommendation for Silverlight

    - by Mathias Weyel
    Hi there, yet another question for recommendations for a book on Silverlight. I look for a book that covers the UI and styling and, if possible, custom drawing and graphics. Very important for me is the style of the book - it should focus on the actual programming and not on where to click in Visual Studio to get things done. Let's take a fictional example for proper usage of the DataGrid control: Bad: To use the data grid, drag it from the toolbox onto the control. You can change the background color by clicking on “Background” in the properties. To define custom columns, click on columns and edit them in the configuration window that opens. Good: To use the DataGrid, you need a reference to the blah dll and declare the namespace in the XAML like this (blah), the data model should be like blah and if you want to define how the columns look like, you need to define them like this (more blah). And if you want to do this in C# because you for whatever reason aren’t able or willing to use XAML, this would look like blah. Bonus points for coverage of topics like how to manage resources (images/fonts) and internationalization. There are quite some snippets on how to do that on the internet but somehow each of them looks like they work but are not a proper way of doing it. cheers Mathias

  • Javascript error: Object required...tough time fixing this

    - by rtnav2301
    The situation is this: a friend of mine asked me to help her with a website she's working on called www.KeepsakePartyInvitations.com. Her original designer created this code but didn't finish the project. So here I am to help save the day. Now, once a photo has been added to the party template and the mouse is placed over the image, an alternate text message appears to the right. The message informs the visitor how to reposition and resize the image, if necessary. I'm testing the procedure in the invitation to reposition the image. I follow the directions about moving the picture, but the mouse does not let go of the photo. Where ever the mouse moves, so does the image. The same thing occurs if you want to resize the image, you follow the directions but the image does not resize. I check the error message in IE 8 and it states: Message: Object required Line: 873 Char: 3 Code: 0 URI: http://www.keepsakepartyinvitations.com/Includes/JCode.js When I checked the Javascript file, the Line 873 states: tempX = e.clientX + document.body.scrollLeft If you review the javascript file, the function where the line is located is called: function getMouseXY(e). Please help me, it has been a long while since I've worked with Javascript and I'm motivated to get this fixed. Thank you!

  • Cross-domain templating with Javascript

    - by Husky
    I'm currently building a Javascript library that can be used to easily create embeddable media based on the URL of a media file, and then be controlled using Javascript methods and events (think something like the Flash / Silverlight JW player). Of course, i could simply cat all the html tags from the Javascript library and send that to the browser: function player(url) { document.write('<object type="foo"><param name="something" value="bar">' + <param name="source" value=" + url + '/></object>'); } But i think this is a very ugly practice that tends to create unmanageable code that is unreadable when you review it a few weeks later. So, a templating solution seems to be the way to go. I've been looking to EJS because it loads the templates using AJAX, so you can manage your templates in separate file instead of directly on the HTML page. There's one 'gotcha' with that: my library needs to be completely cross-domain: the library itself could be located on foo.com while the serving site could be located on bar.com. So if bar.com would want to add a media player using the library it needs to do an AJAX call to a template located on foo.com, which won't work because of the same-origin policy in browsers. AFAIK, there's no library that uses something like JSONP to read and write templates to get around this problem. Could anyone point me to a solution for this problem?

  • Resetting a PChar variable

    - by scott-thornton
    Hi, I don't know much about delphi win 32 programming, but I hope someone can answer my question. I get duplicate l_sGetUniqueIdBuffer saved into the database which I want to avoid. The l_sGetUniqueIdBuffer is actually different ( the value of l_sAuthorisationContent is xml, and I can see a different value generated by the call to getUniqueId) between rows. This problem is intermittant ( duplicates are rare...) There is only milliseconds difference between the update date between the rows. Given: ( unnesseary code cut out) l_sGetUniqueIdBuffer: PChar; FOutputBufferSize : integer; FOutputBufferSize := 1024; while( not dmAccomClaim.ADOQuClaimIdentification.Eof ) do begin // Get a unique id for the request l_sGetUniqueIdBuffer := AllocMem (FOutputBufferSize); l_returnCode := getUniqueId (m_APISessionId^, l_sGetUniqueIdBuffer, FOutputBufferSize); dmAccomClaim.ADOQuAddContent.Active := False; dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pContent').Value := (WideString(l_sAuthorisationContent)); dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pClaimId').Value := dmAccomClaim.ADOQuClaimIdentification.FieldByName('SB_CLAIM_ID').AsString; dmAccomClaim.ADOQuAddContent.Parameters.ParamByName('pUniqueId').Value := string(l_sGetUniqueIdBuffer); dmAccomClaim.ADOQuAddContent.ExecSQL; FreeMem( l_sAuthorisationContent, l_iAuthoriseContentSize ); FreeMem( l_sGetUniqueIdBuffer, FOutputBufferSize ); end; I guess i need to know, is the value in l_sGetUniqueIdBuffer being reset for every row??

  • Querying a database using Cocoa.

    - by S1syphus
    Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

  • Webpage shared with like button not showing in users timeline

    - by einar
    I have a single pages and a one page that lists all of the single pages. On the overview page you can like each single page with their url. And of corse you can do the same when you are viewing a single page. My issue is very strange. Most of the pages that I would like show up on my timeline. But then there are some that don't show after I click like, not even if I click on "Post to Facebook". This page will not show in a users timeline if liked ore "Post'ed to Facebook". http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/valdimar/ But this one will http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/snorri-helgason/ But these pages are excls the same, they use the same template so the code should not be any different, and in fact I cant see any differents between these pages that could be causing this kind of problem. You can view the overview page here http://www.inspiredbyiceland.com/inspiration/iceland-airwaves/ . Most of the single pages work fine and show up on users timeline. Most of the content on the site works fine so far as I know. There is an Facebook application defined on the page. I'm not sure if that is related to this problem.

  • Long text input from user and PDF generation

    - by Petteri Hietavirta
    I have built a web application that can be seen as an overcomplicated application form. There are bunch of text areas with a given character limit. After the form submission various things happen and one of them is PDF generation. The text is queried from the DB and inserted in the PDF template created in iReports. This works fine but the major pain is overflowing text. The maximum number of characters is set based on 'average' text. But sometimes people prefer to write with CAPS or add plenty of linefeeds to format their text. These then cause user's text to overflow the space given in PDF. Unfortunately the PDF document must look like a real application form so I cannot allow unlimited space. What kind of approaches you have used to tackle this? Clean/restrict user input? Calculate the space requirement of the text based on font metrics? Provide preview of the PDF? (too bad users are not allowed to change their input after submission...)

  • Anything speaking against the bitnami.org Ruby/Rails/Redmine Stack?

    - by Pekka
    I am looking to set up a Redmine server on a Windows virtual machine on my local workstation. (Background in this related question.) I have zero knowledge of Ruby nor Rails, and while Redmine may be the opportunity to dip into those platforms somewhat, my first goal is to get it running as quickly and easily as possible. For that, I am eyeing the Bitnami Redmine Package. It promises point-and-click install, and a self-contained environment with everything you need. Apart from the learning factor, are there any serious limitations this method implies? Any serious cutdowns in customizability? I will be wanting to customize the template right away, for example, and install plugins. The package looks o.k. to me but before I install it, I was curious to know whether anybody would advise against it and why. Edit: The first impression is great. From 0 to a working Redmine installation in twelve minutes! Wow.

  • Devise routes to only use custom sign in page

    - by eblume
    I am trying to learn Devise and seem to have hit a problem that is nearly the same as many, many questions here on SO but just slightly different enough that I am not getting much traction following those questions' threads. I have a very simple application. Users can sign in and sign out (and also the devise 'forgot password' stuff is enabled - I am not concerned about it at this time) and that is it. They can't register, they can't edit their profile other than to change their password, they can't do anything except sign in and sign out. (Account creation will, for now, be handled manually at the command line.) I would vastly prefer that the only page that users can log in from was "/" (root_path). I already have it working where you can log in from "/", and that is great. The problem I am having is that if you type in your user/password combination incorrectly from the root_path login page, it automatically sends you to the Devise sign-in page to continue trying to sign in. How can I make Devise redirect to root_path on sign-in failure? Here are my routes - they are probably not optimal or correctly configured and I would appreciate pointers on fixing them: root to: "core_pages#splash" devise_for :users, skip: [:sessions] as :user do # get 'signin' => 'devise/sessions#new', as: :new_user_session post 'signin' => 'devise/sessions#create', as: :user_session delete 'signout' => 'devise/sessions#destroy', as: :destroy_user_session, via: Devise.mappings[:user].sign_out_via end match '/home' => 'core_pages#home' Note the commented-out 'get signin' line. The system works without this line but, surprisingly (to me), "GET /signin" results in a HTTP 400 (OK) response and renders the Devise login template. I would prefer it return some sort of 'invalid request' or just silently redirect the user to root_path. Running rake routes on these routes gives: root / core_pages#splash user_password POST /users/password(.:format) devise/passwords#create new_user_password GET /users/password/new(.:format) devise/passwords#new edit_user_password GET /users/password/edit(.:format) devise/passwords#edit PUT /users/password(.:format) devise/passwords#update user_session POST /signin(.:format) devise/sessions#create destroy_user_session DELETE /signout(.:format) devise/sessions#destroy home /home(.:format) core_pages#home Thanks!

  • How to draw a circle in java with a radius and points around the edge

    - by windopal
    Hi, I'm really stuck on how to go about programming this. I need to draw a circle within a JFrame with a radius and points around the circumference. i can mathematically calculate how to find the coordinates of the point around the edge but i cant seem to be able to program the circle. I am currently using a Ellipse2D method but that doesn't seem to work and doesn't return a radius, as under my understanding, it doesn't draw the circle from the center rather from a starting coordinate using a height and width. My current code is on a separate frame but i need to add it to my existing frame. import java.awt.*; import javax.swing.*; import java.awt.geom.*; public class circle extends JFrame { public circle() { super("circle"); setSize(410, 435); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Panel sp = new Panel(); Container content = getContentPane(); content.add(sp); setContentPane(content); setVisible(true); } public static void main (String args[]){ circle sign = new circle(); } } class Panel extends JPanel { public void paintComponent(Graphics comp) { super.paintComponent(comp); Graphics2D comp2D = (Graphics2D) comp; comp2D.setColor(Color.red); Ellipse2D.Float sign1 = new Ellipse2D.Float(0F, 0F, 350F, 350F); comp2D.fill(sign1); } }

  • getting a tiled image collection on the iPad (deepzoom)

    - by Chris B
    I have a set of tiled image collections created via microsoft's deep zoom composer, and a silverlight app that currently consumes them for display via MultiScaleImage - it's all working pretty well - I'd just like to get some experience with iPad programming and have a couple of ideas for some ipad applications. All my ideas rely on me being able to display/manipulate these tiled image sets (on the iPad). I just picked up a iMac to facilitate this. I'm not seeing any objective-c / cocoa-touch libraries for this though, so am assuming I will have to roll my own. (Saw the seadragon ajax component, which is pretty slick, but I'm dealing with collections here, which it doesn't support. I would also like to roll this as a native app just to get the experience). The only open source project I found for displaying/manipulating the tiled image sets was Openzoom -a flash component. I'm not to familiar with actionscript either (python, java, c#, and c are the only languages I have really used), but briefly inspecting the code I didn't really have any issues with it and can probably use it for hints on how to swap the tiles in and out, etc.. But, as I'm pretty new to obj-c/cocoa-touch, some pointers in the right direction would be appreciated. 1) Are there any other projects out there I am missing, or is openzoom my best bet for some reference? 2) Should I be trying to do this display in the UIKit framework, or should I do it as an OpenGL display? 3) Any other suggestions/pointers that I didn't think to ask.

  • Java method keyword "final" and its use

    - by Lukas Eder
    When I create complex type hierarchies (several levels, several types per level), I like to use the final keyword on methods implementing some interface declaration. An example: interface Garble { int zork(); } interface Gnarf extends Garble { /** * This is the same as calling {@link #zblah(0)} */ int zblah(); int zblah(int defaultZblah); } And then abstract class AbstractGarble implements Garble { @Override public final int zork() { ... } } abstract class AbstractGnarf extends AbstractGarble implements Gnarf { // Here I absolutely want to fix the default behaviour of zblah // No Gnarf shouldn't be allowed to set 1 as the default, for instance @Override public final int zblah() { return zblah(0); } // This method is not implemented here, but in a subclass @Override public abstract int zblah(int defaultZblah); } I do this for several reasons: It helps me develop the type hierarchy. When I add a class to the hierarchy, it is very clear, what methods I have to implement, and what methods I may not override (in case I forgot the details about the hierarchy) I think overriding concrete stuff is bad according to design principles and patterns, such as the template method pattern. I don't want other developers or my users do it. So the final keyword works perfectly for me. My question is: Why is it used so rarely in the wild? Can you show me some examples / reasons where final (in a similar case to mine) would be very bad?

  • Boost lambda: Invoke method on object

    - by ckarras
    I'm looking at boost::lambda as a way to to make a generic algorithm that can work with any "getter" method of any class. The algorithm is used to detect duplicate values of a property, and I would like for it to work for any property of any class. In C#, I would do something like this: class Dummy { public String GetId() ... public String GetName() ... } IEnumerable<String> FindNonUniqueValues<ClassT> (Func<ClassT,String> propertyGetter) { ... } Example use of the method: var duplicateIds = FindNonUniqueValues<Dummy>(d => d.GetId()); var duplicateNames = FindNonUniqueValues<Dummy>(d => d.GetName()); I can get the for "any class" part to work, using either interfaces or template methods, but have not found yet how to make the "for any method" part work. Is there a way to do something similar to the "d = d.GetId()" lambda in C++ (either with or without Boost)? Alternative, more C++ian solutions to make the algorithm generic are welcome too. I'm using C++/CLI with VS2008, so I can't use C++0x lambdas.

  • Suggestions for entering mobile development -- pure iPhone SDK, Andorid SDK. Mono Touch or Titanium?

    - by Tom Cabanski
    I am entering mobile development. I have been working primarily in .NET since 1.0 came out in beta. Before that, I was mostly a C++ and Delphi guy and still dabble in C++ from time to time. I do web apps quite a bit so I am reasonably proficient with Javascript, JQuery and CSS. I have also done a few Java applications. I started web programming with CGI and live mostly in the ASP.NET MVC world these days. I am trying to decide on which platform/OS and tool to select. I am concerned with the size of the market available for my applications as well as the marketibility of the skills I will pick up. The apps I have in mind would work on both phones and pads. Some aspects of what I have in mind will play better on the bigger screens that will be available on pads. Here are the options I am considering: Apple iPhone/iPad using pure Apple SDK (Objective-C) Apple iPhone/iPad using Mono Touch (C#) Android using pure Android SDK (Java) Multiple platforms using something like Titanium to generate native apps from web technologies (HTML, CSS and Javascript) Multiple platforms using HTML5 web applications that run in the browser (HTML, CSS and Javascript). Which option would you choose? Do you have a different suggestion? What are the pros and cons?

I tried this code: #include <stdio.h> #include <stdlib.h> char a[] = "programming"; char *ap = &a[4]; int main(void) { printf("%x %x %x\n", ap, &*(ap), *&(ap)); /* line 13 */ printf("%x %x %x\n\n", ap+1, &*(ap+1), *&(ap+1)); /* line 14 */ } The first printf line (line 13) gives me the addresses: 40b0a8 40b0a8 40b0a8 which are the same as expected. But when I added the second printf line, Borland complains: "first.c": E2027 Must take address of a memory location in function main at line 14 I was expecting to get: 40b0a9 40b0a9 40b0a9. It seems that the expression *&(ap+1) on line 14 is the culprit here. I thought all three pointer expressions on line 14 are equivalent. Why am I thinking wrong? A second related question: The line char *ap = a; points to the first element of array a. I used char *ap = &a[4]; to point to the 5th element of array a. Is the expression char *ap = a; same as the expression char *ap = &a[0]; Is the last expression only more verbose than the previous one? Thanks a lot...

  • Jackrabbit version delete -- name is unexpected

    - by Scudworth
    I'm using Apache Jackrabbit to store versioned data. I'm following the template listed on the Jackrabbit wiki for versioning basics, but there's one thing that isn't working as expected. After I run the code from the wiki, I try saving another version of the node, then getting its version string: child = parentNode.getNode("childNode"); child.checkout(); child.setProperty("anyProperty", "Blah3"); session.save(); Version thisVersion = child.checkin(); System.out.println(thisVersion.getName()); The output of this code is 1.0.0 , when I want it to be 1.1 . My goal is to be able to remove the last -- and only the last -- version of a node, and have the next version have the same name as the removed version. I only care about doing this when the node is being added; if I can check in the node, and read the name (to get the version number) without an exception being thrown, I'm fine with not being able to remove the version. Looking around the internet, I can't find a way to accomplish this.
