• Change list link to foreign key change page

  - by Adam

  When viewing the admin change list for a model, is it possible to make the columns that correspond to foreign keys links to their respective pages? A simple example is I have a Foo object which contains Bar as a foreign key. If I'm viewing the admin change list for Foo (and have it set to include Bar in the display_list columns), the main column would link to the Foo instance's edit page while the Bar column would link to the Boo instance's edit page. I understand I can override the template that's used, but I was curious if there was a solution that didn't require that.

• PHP include(): File size & performance

  - by Tom

  An inexperienced PHP question: I've got a PHP script file that I need to include on different pages lots of times in lots of places. I have the option of either breaking the included file down into several smaller files and include these on a as-needed basis... OR ... I could just keep it all together in a single PHP file. I'm wondering if there's any performance impact of using a larger vs. smaller file for include() in this context? For example, is there any performance difference between a 200KB file and a 20KB file? Thank you.

• Choose between multiple options with defined probability

  - by Sijin

  I have a scenario where I need to show a different page to a user for the same url based on a probability distribution, so for e.g. for 3 pages the distribution might be page 1 - 30% of all users page 2 - 50% of all users page 3 - 20% of all users When deciding what page to load for a given user, what technique can I use to ensure that the overall distribution matches the above? I am thinking I need a way to choose an object at "random" from a set X { x1, x2....xn } except that instead of all objects being equally likely the probability of an object being selected is defined beforehand.

• Where should I place a function that I want to run before the cached page is served (Drupal)

  - by kidbrax

  We have a intranet site that runs on Drupal. If an employee hits the site from outside our network they are required to login first. If they are already in our network, they can browse around freely. So we have a function that checks where they are coming from and redirects them to a login page if they are from outside. If we enable caching, they are not redirected because the cached page is rendered without running our function. The code currently exists inside of the theme_preprocess function. Where can I put it so that it always runs before the cached pages are served?

• Render Order via HTML or CSS

  - by Bullines

  What is the best practice is in the case of altering the render order of elements on a webpage. For example, I have two DIVs that are to be displayed on a page: <div id="appleSection"> <!-- Apple DIVs, content, form elements, etc --> </div> <div id="orangeSection"> <!-- Orange DIVs, content, form elements, etc --> </div> Depending on user selection (perhaps by country or something), the order which the DIVs are presented to the user can differ. Certain conditions present appleSection above orangeSection, and for other conditions, their order is reversed. If the core logic of the page is the same regardless, is it a best practice to determine order on the server-side (perhaps via two pages that differ in the order of the DIVs), or is it more appropriate to have just a single page and use CSS to control whether appleSection is above orangeSection or vice versa?

• How to make a custom template in WordPress work as a password protected page?

  - by KaOSoFt

  I'm building a page with a custom template. The thing is, I need this page to be password protected, or at least accessible to logged in users, but even if I set it as such (Private/Password protected) in the New Pages section in WordPress Administration, it won't display the menu entry nor the content (if Private) or it would show the page contents immediately (if Password protected). I've read somewhere that the_content() function is what makes this work, but as you can guess, my custom template doesn't use the_content() at all, and it's all based on custom content. Do you happen to know how can I (re)implement these two options?

• Cascading MVC controllers with CatchAll Routes

  - by Richard

  Hi, I have an MVC app which has its routes defined with the final route being a catch all route to a "PageController" for a database driven collection of pages. What I want to achieve is to be able to plugin to the app a second controller to the catch all route which the first controller passes on to if it does not find the url recieved in the database. Effectively I want to queue up controllers with catch all actions: public ActionResult PageCatchall(string url) { var page = repository.Get<Page>(string url); if (page != null) { // Handle the request return View(page) } // Otherwise pass to a new controller ???? } Anyone have any good ideas as to how to solve this? I have tried RedirectToAction but that requires that the next controller has a different route to the action. I have tried ActionInvoker but this failed to work the way I did it.

• How to correctly migrate urls from custom asp.net solution to Wordpress?

  - by Marek

  I have a web site built using asp.net with ugly URLs like /DisplayContent.aspx?id=789564. I know how to migrate the database, but the Wordpress urls will be (naturally) different. Can I simply write some mapping or do I have to include a rewrite rule for each subpage (300 pages) in .htaccess? Should I provide a rewrite rule for each existing page that would transform a full old url to the known new url, like for example: /DisplayContent.aspx?id=789798 -> /2010-5-10/Title-Of-The-Post Even if I manage to migrate the URLs, the structure of the HTML for the new content will naturally be different. How does this affect SEO? Should I run asp.net and wordpress side by side and issue the redirects from the asp.net application? What is the most efficient solution to this kind of migration of URLs without doing PHP programming?

• Is it possible to have a .NET route that maps to the same place as a directory?

  - by Austin

  I'm building a CMS using WebForms on .NET 4.0 and have the following route that allows URLs like www.mysite.com/about to be mapped to the Page.aspx page, which looks up the dynamic content. routes.MapPageRoute("page", "{name}", "~/Page.aspx"); The problem is that I have a couple of folders in my project that are interfering with possible URLs. For example, I have a folder called "blog" where I store pages related to handling blog functionality, but if someone creates a page for their site called "blog" then navigating to www.mysite.com/blog gets the following error: 403 - Forbidden: Access is denied. You do not have permission to view this directory or page using the credentials that you supplied. Other similar URLs route correctly, but I think because .NET is identifying /blog as a physical location on the server it is denying directory access. Is there a way to tell IIS / .NET to only look for physical files instead of files and folders?

• avoid caching of page in browser

  - by Shan

  I am using an iframe to show the child pages.In that one one particular page contains hidden div and i am showing it as a pop-up like thing with javascript by changing the visibility of the hidden div. Problem is before showing the hidden div , some manipulations are done at server level and I am calling the div from C# code after the manipulations like Page.ClientScript.RegisterStartupScript(GetType(), "MyKey", "javascript:OpenModelPopup('cb','cs');", true); so the page is getting posted back and the div is shown. after this, after going to next page if i click browser back it shows that page with that hidden div and on next click of browser back gives the page without hidden div. but I want to show only the initial stage of the page ie. without showing the hidden div that stage with hidden div should not be cached or it should not be shown on click of browser back.

• Question about software that tracks divs better than notepad++

  - by Jeff

  I recently got hired as a web developer, and the project that I am overseeing has a formatting issue on one of the pages because one of the divs is out of whack. It is a fairly complex page with quite a bit of php, and from what I can gather, I am missing a </div> tag somewhere, and accordingly everything is messed up. I am currently using notepad++, which is decent at lining up divs, meaning that if you click on the opening div tag, it will highlight purple and also highlight the closing one. But it seems as though if you have div tags that span several lines (hundreds) it won't work. Has anyone else run into a similar situation? Is there a better editor I could be using that would do a better job of helping me with my div issue? Or do I have to go through and line up the divs 1 by 1? (there are like over 100). Please let me know!! Thanks

• Paging with jQuery

  - by zurna

  I get data from another page using jQuery get method. But I have a small problem. Sometimes, data that I take from another page is too long so it's divided into pages. When the user clicks on 1, 2, 3, ... links he/she is redirected to the other page. However, I want data to be reloaded on the same page. Edit $('ul.thumbs li.pagination a').live('click', function() { var pageNumber = parseInt($(this).text().replace(/[^0-9]/g, '')); $.ajax({ type: "GET", url: "images.cs.asp?Process=ViewImages&PAGEID=<%=Request.QueryString("PAGEID")%>", success: function(data) { $("#ViewImages").html(data); }, error: function (XMLHttpRequest, textStatus, errorThrown) { $("#ViewImages").html('.'); } }); return false; });

• Questions to ask a client before beginning a website

  - by Jason

  I am aware of this question which deals with the technical aspects of website construction, but I was unable to find any place with suggestions on knowledge you must obtain from a client before undergoing a project. As someone who freelances on the side, I think this could be incredibly useful. What important questions must one ask the client (and require an answer to) before undergoing a website? or, in other words, What must you know about the project before starting it? This can range from "When do I get paid?" to "How many pages will the site be?". I believe this is relevant to programming because you must know how to communicate with your client to get all the information necessary before you can begin programming. If not, downstream changes can put a serious delay on the project from things not hashed out beforehand. Thanks!

• TypeError: Result of expression 'printWindow' [undefined] is not an object.

  - by orangebrainer

  I'm trying to create hidden iframes in my page dynamically to load 3 other pages so that i can grab all the HTML and combine them into 1 in a new window. However i'm stuck at this. tHe frames are created fine. But whenever the javascript runs to the part of function openNewWindow() { var printWindow = window.open("",""); printWindow.document.open(); printWindow.document.write(HTMLfromFrames); printWindow.document.close(); } i get this error: TypeError: Result of expression 'printWindow' [undefined] is not an object. but if i generate a button to call this function seperately, it works fine. however i need it to run all in one click event Anybody has any idea what's wrong? Thanks!

• Get CSS style from PHP

  - by rpSetzer

  I am parsing pages using Simple DOM parser. It is neat, but I would like to get the applied css style for each element. Not only the inline styles, but every style it applies to that element, being it inline, in-page or external. Is there a class that does that? If not, how would you do it? I do not really care about overriding styles, cascade, or browser specific styles. Having all the directly applied styles would suffice.

• SVN files edited thru FTP, How do I fix the edited files so they work thru SVN again?

  - by Bobby

  Basically, a 3rd party analyst we brought on to make some improvements to our site decided to edit files directly on the live server threw FTP. Any time we make changes to those pages threw SVN we have PHP parse errors. Things should be edited threw the SVN and committed. We have our working copies setup so we can edit them how ever we want while having them running under apache for testing. We commit all of our changes to a local repository, then commit from there to the live server. The code on the live server that causes the parse error has " .mine" and " .rxxxx", and my question is, how can I revert those files back to before they were edited thru FTP so I can update them threw SVN again?

• Sharepoint as a replacement for N-Tiers Applications and OLTP Databases

  - by user264892

  All, At my current company, we are looking to replace all ASP.NET Applications and OLTP databases with Sharepoint 2007. Our applications and databases deal with 10,000+ rows, and we have 5,000 + clients actively using the system. Our Implementation of sharepoint would replace all n-tier applications. Does anyone have an experience in implementing this? My current viewpoint is that Sharepoint is not built for or adequate enough to handle this type of application. Can it really replace application with hundreds of pages, and hundreds of tables? Support Data warehousing operations? Support high performance OLTP operations? Provide a robust development environment? Any and all input is greatly appreciated. Thanks S.O. Community.

• How to trigger an event ONLY if both dropdowns are selected?

  - by DaveDev

  I have a dropdown select list on my page of class="TypeFilter". I have a jQuery event that fires when a value in that list is selected. $(".TypeFilter").change(function() { // Extract value from TypeFilter and update page accordingly )); I now have to add another list to the page, and I want to implement functionality which will prevent the .change(function() from running unless both are selected. In both lists the first option in the list is some text instructing the user to select one of the items, so I was thinking of just writing some logic to test that both lists have a selected index greater than 0. I think this is a touch unclean though, especially considering that other pages that have a TypeFilter use the same logic. Is there any nifty functionality in jQuery that can do this?

• Creating a page selector with JSP/JSTL

  - by zakSyed

  I am working on a project where I am required to build a page somewhat similar to the one you see when you visit a website like blockbuster. When you click on browse more you are taken to a page with a bar on top with different page numbers and a drop down to select the number of pages you want to view on that page. I want to include a feature like that on my page but I am not sure where to start. In my page I have list of 200 items which I want to display page by page. I was suggested to use custom tags, but is there a more simpler or efficient way to create that functionality. My web application uses Spring MVC framework and is coded entirely in Java. Any suggestions will be appreciated.

• Comapring pitches with digital audio

  - by user2250569

  I work on application which will compare musical notes with digital audio. My first idea was analyzes wav file (or sound in real-time) with some polyphonic pitch algorithms and gets notes and chords from this file and subsequently compared with notes in dataset. I went through a lot of pages and it seems to be a lot of hard work because existing implementations and algorithms are mainly/only focus on monophonic sound. Now, I got the idea to do this in the opposite way. In dataset I have for example note: A4 or better example chord: A4 B4 H4. And my idea is make some wave (or whatever I don't know what) from this note or chord and then compared with piece of digital audio. Is this good idea? Is it better/harder solution? If yes can you recommend me how to do it?

• How do I make a DIV stay at the top of the screen no matter ow far down the page my visitor scrolls?

  - by user1289863

  What I'm saying is, I have some extremely long pages on my website, which can make it annoying I've my visitors need to scroll to the top of the page to be able to navigate to another page. I'm not quite sure what I would call this but any Google search that contains the words 'DIV' and 'float' come up with completely unrelated results... What I'm looking to do is create a DIV that stays at the top of the Screen (not to be confused with the page) so that if the user is at the bottom of the page, they can still see the navigation bar just floating at the top of the screen. What I can think of is to position the DIV relative to the position of the screen but I don't know how to code this. I'm happy to use JavaScript (preferably in the form of jQuery), but if you know how to do this using CSS, I would favour your response. This might help: I know a little bit of jQuery and JavaScript and I know a good deal of CSS and HTML. Thanks in advance.

• .NET web service call slower when performed asynchronously

  - by joelt

  I have an ASP.NET site, and some pages need to call a web service. I used Visual Studio's "Add Web Reference" to auto-generate classes and methods for the web service. When I call the service synchronously, i.e. objService.MethodName("param1"), a call might take a second or so. When I call it asynchronously, i.e., objService.BeginMethodName("param1", AddressOf MyCallback, Nothing), it typically takes about 6 seconds. When debugging, it appears that the bulk of the time is spent waiting between the completion of the BeginMethodName call and the beginning of MyCallback. Does the thread switching really incur that much overhead? Is there another reason for this?

• How to modify CSS when requirements change?

  - by DaveDev

  Suppose I'm given the requiremnt to geneate a few pages that have tables on them. The original requirement is for all tables to be 500px. I'd write my CSS as follows: table { width: 500px; } That will apply accross the board for all tables. Now, what if they change the requirment so that some tables are 600px. What's the best way to modify the CSS? Should I give the tables classes so table.SizeOne { width: 500px; } table.SizeTwo { width: 600px; } Or is there a better way for me to deal with changes like this?
