  • htaccess rewriterule

    - by user322731
    I currently have this rule where I want the page to just render my static content. RewriteRule ^videos\/coverage\/view\/236159\-([0-9a-zA-Z-]+) http: //website.com/static/236159.html [NC] However, this doesn't work. It works with a L tag but then the URL is different: RewriteRule ^videos\/coverage\/view\/236159\-([0-9a-zA-Z-]+) http: //website.com/static/236159.html [L, NC] My goal is to keep the URL the same but the content different. Can anyone point out to what flags are needed in order to get this working properly? Thanks!

  • Unicode and PHP - am I doing something wrong?

    - by alex
    I'm using Kohana 3, which has full support for Unicode. I have this as the first child of my <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> The Unicode character I am inserting into is é as in Café. However, I am getting the triangle with a ? (as in could not decode character). As far as I can tell in my own code, I am not doing any string manipulation on the text. In fact, I have placed the accent straight into a view's PHP file and it is still not working. I copied the character from this page: http://www.fileformat.info/info/unicode/char/00e9/index.htm I've only just started examining PHP's Unicode limitations, so I could be doing something horribly wrong. So, how do I display this character? Do I need to resort to the HTML entity?

  • JavaScript snippet that populates the table

    - by kayn
    I would like to write a JavaScript snippet that populates the table based on the selection, and not create several details panes and toggle their visibility. I tried implement this using the following code but its not working as desired,firstly,it only works with internet explorer under certain conditions and it just toggles visibility of detail panes;Below is my code; <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <HTML> <HEAD> </HEAD> <BODY onLoad="tblTB_0.style.display='';tblTB_1.style.display='none'; tblTB_2.style.display='none'; tblTB_3.style.display='none'"> <center> <table> <tr> <td> <H1> <align="left"> Candi Colledge of Computing <br/>Course Page </H1> </td> </tr> </table> </center> <hr> </br> <H2><P STYLE="color: blue">Honours Courses.</H2> <left> <p><a href="" onclick="tblTB_1.style.display=''; tblTB_2.style.display='none'; tblTB_3.style.display='none'"> Concurrent Programming</a> <br/> <a href="" onclick="tblTB_1.style.display='none';tblTB_2.style.display=''; tblTB_3.style.display='none'">Simulation of Networks</a><br/> <a href="" onclick="tblTB_1.style.display='none';tblTB_2.style.display='none'; tblTB_3.style.display=''">Advanced Computer Science Topics</a></p> <br> <table style="table-layout: fixed"; border=1> <colgroup> <col width="100px"><col width="150px"><col width="150px"> </colgroup> <tbody id="tblTB_0"> <tr> <td>Course Code</td> <td>Lecturer</td> <td>Hours/Week</td> <td>Credits</td> </tr> </tbody> <tbody id="tblTB_1"> <tr> <td>RW 714</td> <td>Dr. kate</td> <td>2 hrs</td> <td>15</td </tr> </tbody> <tbody id="tblTB_2"> <tr> <td>RW 742</td> <td>Prof. Broz</td> <td>4 hrs</td> <td>10</td> </tr> </tbody> <tbody id="tblTB_3"> <tr> <td>RW 716</td> <td>Consultant</td> <td>3 hrs</td> <td>12</td> </tr> </tbody> </table> </left> <br> </BODY> </HTML>

  • Parsing a website

    - by Phenom
    I want to make a program that takes as user input a website address. The program then goes to that website, downloads it, and then parses the information inside. It outputs a new html file using the information from the website. Specifically, what this program will do is take certain links from the website, and put the links in the output html file, and it will discard everything else. Right now I just want to make it for websites that don't require a login, but later on I want to make it work for sites where you have to login, so it will have to be able to deal with cookies. I'll also want to later on have the program be able to explore certain links and download information from those other sites. What are the best programming languages or tools to do this?

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

    - by user1055380
    I wanted to convert an array with some css, js and html files into a zip file and save them in ownCloud (it has it's own framework but it's knowledge is not required.) What I am saving is an infinite loop of zip files, as in, a zip inside a zip so I can't even check that the code is working correctly or not. Please help. Here is the link to the code. <?php /* creates a compressed zip file */ $filename = $_GET["filename"]; function create_zip($files = array(),$destination = '',$overwrite = false) { //if the zip file already exists and overwrite is false, return false if(file_exists($destination) && !$overwrite) { return false; } //vars $valid_files = array(); //if files were passed in... if(is_array($files)) { //cycle through each file foreach($files as $file => $local) { //make sure the file exists if(file_exists($file)) { $valid_files[$file] = $local; } } } //if we have good files... if(count($valid_files)) { //create the archive $zip = new ZipArchive(); if($zip->open($destination,$overwrite ?

  • Creating a generic NotFound View in ASP.MVC

    - by George
    Hello guys, I'm having a problem to create a generic View to represent NotFound pages. The view is created and it's fine. I need to know how i can direct the user to the NotFound view in my Controllers and how to render a specific "Return to Index" in each controller. Here is some code: public class NotFoundModel { private string _contentName; private string _notFoundTitle; private string _apologiesMessage; public string ContentName { get; private set; } public string NotFoundTitle { get; private set; } public string ApologiesMessage { get; private set; } public NotFoundModel(string contentName, string notFoundTitle, string apologiesMessage) { this._contentName = contentName; this._notFoundTitle = notFoundTitle; this._apologiesMessage = apologiesMessage; } } // NotFound View <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Geographika.Models.NotFoundModel>" %> <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> <%= Html.Encode(Model.ContentName) %> </asp:Content> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <h2><%= Html.Encode(Model.NotFoundTitle) %></h2> <p><%= Html.Encode(Model.ApologiesMessage) %></p> <!-- How can i render here a specific "BackToIndexView", but that it's not bound to my NotFoundModel? --> </asp:Content> // Controller piece of code // // GET: /Term/Details/2 public ActionResult Details(int id) { Term term = termRepository.SingleOrDefault(t => t.TermId == id); if (term == null) return View("NotFound"); // how can i return the specific view that its not bound to Term Model? // the idea here would be something like: // return View("NotFound",new NotFoundModel("a","b","c")); else return View("Details", term); } I'm not sure how to redirect to a whole different page. Can anyone give me any pointers? Thanks

  • Data Access from single table in sql server 2005 is too slow

    - by Muhammad Kashif Nadeem
    Following is the script of table. Accessing data from this table is too slow. SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO CREATE TABLE [dbo].[Emails]( [id] [int] IDENTITY(1,1) NOT NULL, [datecreated] [datetime] NULL CONSTRAINT [DF_Emails_datecreated] DEFAULT (getdate()), [UID] [nvarchar](250) COLLATE Latin1_General_CI_AS NULL, [From] [nvarchar](100) COLLATE Latin1_General_CI_AS NULL, [To] [nvarchar](100) COLLATE Latin1_General_CI_AS NULL, [Subject] [nvarchar](max) COLLATE Latin1_General_CI_AS NULL, [Body] [nvarchar](max) COLLATE Latin1_General_CI_AS NULL, [HTML] [nvarchar](max) COLLATE Latin1_General_CI_AS NULL, [AttachmentCount] [int] NULL, [Dated] [datetime] NULL ) ON [PRIMARY] Following query takes 50 seconds to fetch data. select id, datecreated, UID, [From], [To], Subject, AttachmentCount, Dated from emails If I include Body and Html in select then time is event worse. indexes are on: id unique clustered From Non unique non clustered To Non unique non clustered Tabls has currently 180000+ records. There might be 100,000 records each month so this will become more slow as time will pass. Does splitting data into two table will solve the problem? What other indexes should be there?

  • Using jsAnim.js

    - by mark
    I've been trying to set up a basic test animation using jsanim.js and using their example site to set up my html, css and js. However, I just can't figure it out (not a developer...designer!) and there isn't just a simple html, css, js file to download showing how to say animate a DIV left to right. The examples of how the library works are clear but I'm lacking something in the set up and looking at their source on the site is nuts...too much going on in there. Thanks to anyone with experience with jsAnim.js http://www.jsanim.com Best, Mark

  • HTML5 Doctype Support

    - by Metropolis
    Hey Everyone, For a long time I have been using XHTML1.1 because I thought I was cool (yeah right). However, today I read Ian Hickson's Article about how everyone uses the wrong MIME type with XHTML and it opened my eyes a lot. I happen to be one of those people who are serving XHTML with text/html MIME, because like a lot of people, W3C says its "ok" to serve it this way. At the top of that article he says that "now" he would serve it using the HTML5 doctype (!DOCTYPE HTML). What are your thoughts about doing this? If I did not use unsupported functionality, would it be ok? What would the MIME type be in this case? Thanks for any help, Metropolis

  • Dynamically added script causes problems

    - by Derk
    I'm loading an html snippet via ajax to append to a div (I use jquery). A part of the html loaded with ajax looks like this: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var options = { mapTypeId : google.maps.MapTypeId.TERRAIN } alert('test'); var map = new google.maps.Map(document.getElementById('map-canvas'), options); </script> Then this is appended with contentBox.append(data); The problem is that this causes a black page in Firefox which keeps loading. In other browsers it seems that the code is not executed at all. Is there a solution for this?

  • Django: way to test what class a generic relation content_object is?

    - by bitbutter
    In my project I have a class, NewsItem. Instances of NewsItem act like a wrapper. They can be associated with either an ArtWork instance, or an Announcement instance. Here's how the NewsItem model looks: class NewsItem(models.Model): content_type = models.ForeignKey(ContentType) object_id = models.PositiveIntegerField() content_object = generic.GenericForeignKey('content_type', 'object_id') date = models.DateTimeField(default=datetime.datetime.now,) class Meta: ordering = ('-date',) def __unicode__(self): return (self.title()) In a template I'm dealing with a NewsItem instance, and would like to output a certain bunch of html it it's 'wrapping' an Artwork instance, and a different bunch of html if it's wrapping an Announcement instance. Could someone explain how I can write a conditional to test for this? My first naive try looked like this: {% if news_item.content_object.type=='Artwork' %}do this{% else %}do that{% endif %}

  • Adding a new view to a Window-based app (re: MapKit tutorial)

    - by blackkettle
    I'm trying add a new view in a window-based application but not really getting anywhere. I've been going through a great MapKit tutorial lately, http://mithin.in/2009/06/22/using-iphone-sdk-mapkit-framework-a-tutorial/ and have successfully set it up and added some further buttons and customizations. However I've gotten stuck at what I assume ought to be a brain-dead simple step. I have added a toolbar to the bottom of the app, and a 'settings' style button. Following this I created a SettingsViewController complete with it's own view. Now I'd like to connect them but I've had absolutely no luck trying to figure out how to do this. I've also gone through several other good tutorials lately, http://miketeo.net/wp/index.php/2008/08/31/simple-iphone-tutorial-part-1.html http://blog.webscale.co.in/?p=228 http://www.iphonesdkarticles.com/2009/01/uitableview-searching-table-view.html but I've gotten lost trying to tie these two bits together. I'm sure it is quite trivial to link these two items but I've had no luck.

  • How to handle model state errors in ajax-invoked controller action that returns a PartialView

    - by Robert Koritnik
    I have a POST controller action that returns a partial view. Everything seems really easy. but. I load it using $.ajax(), setting type as html. But when my model validation fails I thought I should just throw an error with model state errors. But my reply always returns 500 Server error. How can I report back model state errors without returning Json with whatever result. I would still like to return partial view that I can directly append to some HTML element. Edit I would also like to avoid returning error partial view. This would look like a success on the client. Having the client parse the result to see whether it's an actual success is prone to errors. Designers may change the partial view output and this alone would break the functionality. So I want to throw an exception, but with the correct error message returned to the ajax client.
