  • What's the best way to develop a debugging window for an ajax ASP.Net MVC application

    - by KallDrexx
    While developing my ASP.NET MVC, I have started to see the need for a debugging console window to assist in figuring out what is going right and wrong in my code. I read the last few chapters of the Pro Asp.net MVC book, and the author details how to use http modules to show page load/creation times and linq to sql query logs, both of which I definitely want to be able to see. However, since I am loading a lot of small sections of my page individually with ajax I don't want the debug information right there in the middle of my screen. So the idea I came up with was to have a separate browser window (open-able by a link or some javascript) with a console log, that can contain logged entries both from javascript and from the asp.net mvc run. The former should be relatively easy, but I'm having trouble coming up with a way to log the asp.net information in ajax requests. The direction I have been thinking of going is to create an httpmodule (like the Pro MVC book does), and have that module contain some that append the javascript's log to console calls with the messages. The issue I see with this is finding a way to get the log messages from the controller's action methods to the httpmodule's methods. The only way I see to do this is with a singleton, but I'm not sure if singletons are bad practice for a stateless web application. Furthermore, it seems like if I return json with my ajax calls (instead of pure html) then that won't work at all anyways and unless there is a way to add data to an existing json structure inside the httpmodule. How does everyone else handle this type of debugging in heavily ajax applications? For reference, the javascript library I am using is jquery.

  • php question regarding arrays

    - by Martin
    Hi there, I'm a (complete) php noob and need a little help with something. I'm working on a project whereby a user can select up to 6 categories via a form (I'm using ExpressionEngine). The output is like this: "Cat1","Cat2","Cat3" ...and so on. The user can select up to 6 categories on that form. What I need: even if my result is 3 categories I need to have 6 'cells' - for want of a better word - even if they're empty: "Cat1","Cat2","Cat3","","","" I've tried this: <?php $str = '(output goes here)'; print_r(explode(',', $str, 6)); ?> ...but the output give me: Array ( [0] => Cat1 [1] => Cat2 [2] => Cat3 [3] => [4] => [5] => ) How do I get from that to this: "Cat1","Cat2","Cat3","","","" Does this make sense? Thanks Martin

  • Special characters in PHP / MySQL

    - by Jonathan
    Hi, I have in the database words that include special character (in Spanish mostly, like tildes). In the database everything is saved and shown correctly with PHPmyAdmin, but when I get the data (using PHP) and display it in a browser, I get a weird character, like a "?" with a square... I need a general fix so I don't need to escape each character every time, and also I would be able to insert special Spanish characters from a PHP form into the database... The HTML is correct: <meta http-equiv="content-type" content="text/html; charset=utf-8" /> All tables and databas are set to utf8_spanish The character I get: ? Any suggestions??? Thanks!!!

  • Simple PHP Regex question

    - by Dave Kiss
    Hi all, I'd like to validate a field in a form to make sure it contains the proper formatting for a URL linking to a Vimeo video. Below is what I have in Javascript, but I need to convert this over to PHP (not my forte) Basically, I need to check the field and if it is incorrectly formatted, I need to store an error message as a variable.. if it is correct, i store the variable empty. // Parse the URL var PreviewID = jQuery("#customfields-tf-1-tf").val().match(/http:\/\/(www.vimeo|vimeo)\.com(\/|\/clip:)(\d+)(.*?)/); if ( !PreviewID ) { jQuery("#cleaner").html('<div id="vvqvideopreview"><?php echo $this->js_escape( __("Unable to parse preview URL. Please make sure it's the <strong>full</strong> URL and a valid one at that.", 'vipers-video-quicktags') ); ?></div>'); return; } The traditional vimeo url looks like this: http://www.vimeo.com/10793773 Thanks!

  • PHP CLI application debug in ZendStudio (STDIN)

    - by Yuriy
    0 I am trying to debug php CLI using Zend Studio. My problem: I can't get user input from keyboard. This is part of code (method in some class): public function getInput($promt = null, $defaultValue = null) { if(!isset($promt)){ $promt = self::$DEFAULT_PROMPT; } echo $promt; $stdin = fopen ( "php://stdin", "r" ); $val = fgets ( $stdin ); return $val; } So ZS walks through code quite ok, but it stops at $val=fgets() And I have no clue where am I supposed to enter something from keyboard. I tried in console, and everywhere, I chacked debug configuration (Allocate console = on) etc. HELP!

  • PHP Simple modification/correction

    - by Adrian M.
    Hello, I got this code from someone, it's almost perfect to create a dynamic breadcrumb, but there just a little glitch because it echoes two dividers before the breadcrumb: $crumbs = explode("/",$_SERVER["REQUEST_URI"]); foreach($crumbs as $crumb){ echo ucfirst(str_replace(array(".php","_"),array(""," "),'>' . $crumb)); } it echoes: "contentcommonfile" what I want it to look like is "contentcommon1" and also I will deeply appreciate if someone can tell me how can I add links for all the items in the array except the last one (file)? Thank you so much everybody, this website really helped me a lot to learn php by examples!

  • asp:repeater events - how to postback

    - by Kieran
    Hello I have an ASP:Repeater Which I would like to display a list of check boxes in. These check boxes are related to a list of user preferences and the users resulting answer. See Code Bellow. I would like to add do one of the following if possible Option 1: It would be great if I could use the Event in the Repeater:OnItemCommand(...) to fire if any of the items change. It would seem to me that this event will only fire if there is a Button | LinkButton | ImageButton item in the list. IE it will not fire if I put in a check box with AutopostBack="True" Option 2: Is there a way I could attach a method to an Event of CheckBox:CheckChanged I would need to pass this method a parameter saying which question/answer combo to change. Option 3: Its your answer if you know an easier way that would be awesome. The Code: <asp:Repeater ID="RPTprefs" runat="server" DataSourceID="getAnswers" OnItemCommand="RPTprefs_ItemCommand"> <ItemTemplate> <li><asp:CheckBox ID='questionID' runat="server" Checked='<%# Eval("pr.up_is_selected") %>' Text='<%# Eval("prp.prefs_question") %>' AutoPostBack="true" OnCheckedChanged="CheckChanged" /></li> </ItemTemplate> </asp:Repeater> Thanks in advance

  • ImageMagick: convert png fail via PHP and works via bash shell

    - by wedix
    I've got a very weird bug which I've yet to find a solution. UPDATE see solution below What I am trying to do is convert a full size picture into a 160x120 thumbnail. It works great with jpg and jpeg files of any size, but not with png. ImageMagick command: /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' PHP function (shortened) ... $cmd = "/opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png'"; exec($cmd, $output, $retval); $errors += $retval; if ($errors > 0) { die(print_r($output)); } When this function runs $retval equal 1 which means the convert command failed (thumbnail isn't created). This is where it gets interesting, if I run the exact same command in my shell, it works. wedbook:~ wedix$ /opt/local/bin/convert '/WEBSERVER/images/img_0003-192-10.png' -thumbnail x320 -resize '320x<' -resize 50% -gravity center -crop 160x120+0+0 +repage -quality 91 '/WEBSERVER/thumbs/small_img_0003-192-10.png' wedbook:~ wedix$ I've tried using different PHP function such as system, passthru but it didn't work. I thought maybe someone here knew the solution. I'm using MAMP 1.7.2 Apache/2.0.59 PHP/5.2.6 Thanks! UPDATE I updated the following dependencies libpng from 1.2.35 to 1.2.37 libiconv from 1.12_2 to 1.13_0 ImageMagick 6.5.2-4_1 to 6.5.2-9_0 However, it did not fix my problem. 2nd UPDATE I finally found something that might help, when the function runs this is what gets printed in the Apache logs: dyld: Library not loaded: /opt/local/lib/libiconv.2.dylib Referenced from: /opt/local/bin/convert Reason: Incompatible library version: convert requires version 8.0.0 or later, but libiconv.2.dylib provides version 7.0.0 3rd UPDATE libiconv.2.dylib is version 8.0.0... bash-3.2$ otool -L /opt/local/lib/libiconv.2.dylib /opt/local/lib/libiconv.2.dylib: /opt/local/lib/libiconv.2.dylib (compatibility version 8.0.0, current version 8.0.0) /usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 1.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 111.1.4) 4th UPDATE Problem was related to MAMP, see solution below

  • jQuery to PHP: no input... kinda

    - by Seva Alekseyev
    Hi all, I'm using jQuery to post HTTP requests to my PHP page (Apache/Linux, if that matters). I carefully validate on the client so that empty requests are not sent. However on occasions, I'd get an empty request like this: - $_POST collection empty ($_GET collection also empty); - Content-Length is nonzero (a number below 100, consistent with a valid POST from my script) - Content-Type properly application/x-www-form-urlencoded - reading from php://input yields an empty string It's as if $_POST is somehow eaten on the way. I checked the code very carefully - I don't do anything to the contents of $_POST. Any ideas, please?

  • database security with php page that spits out XML

    - by Rees
    Hello, I just created a PHP page that spits outs some data from my database in an XML format. This data is fetched from a flex application I made. I had spent a long time formatting my tables and database information and do not want anyone to be able to simply type www.mysite.com/page_that_spits_out_XML.php and steal my data. However, at the same time I need to be able to access this page from my flex application. Is there a way I can prevent other people from doing this? Thank you!

  • custom php library with pear local installation

    - by andreas
    Hello i wish to be able to deploy a PHP web application along with a local installation of PEAR. To be more specific, i am trying to find a way to do a 'per-application' or local installation of PEAR if this is possible. For example: The application 'MyApplication' is located in: /var/www/applications/myapplication The php library is located in: /var/www/applications/myapplication/library I am looking for a way to do a per-application installation of PEAR since not all applications are managed by me (and i want to control which PEAR packages are installed and when). I found some tutorials for a local PEAR installation (on a shared host) but i don't know if my scenario fits the one for a local PEAR installation. Any thoughts/help appreciated.

  • Use WPF DLL Assembly in ASP.NET problem

    - by liimur
    Hello, I have C++ project that compiles as DLL Assembly in .NET 3.5 SP1 Project is used for Image rendering processing by using WPF (it loads 2 images from local folder, applies one image on another and saves the output file in the same folder). I want to use that that project as a reference in ASP.NET project to the rendering on the website. So I created simple Web Project in ASP.NET C# that uses C++ project as a Reference. Everything works great in ASP.NET Web Development Server (built-in Web server in VS2008). But once I publish this project to IIS on the same Machine or use IIS for debug instead of built-in Web server Image rendering it's not working anymore. I'm not getting any exceptions or error messages, it just output image is not processes as it supposed to be. If anyone know what could cause that I would really appreciate your insight!

  • Performance of tokenizing CSS in PHP

    - by Boldewyn
    This is a noob question from someone who hasn't written a parser/lexer ever before. I'm writing a tokenizer/parser for CSS in PHP (please don't repeat with 'OMG, why in PHP?'). The syntax is written down by the W3C neatly here (CSS2.1) and here (CSS3, draft). It's a list of 21 possible tokens, that all (but two) cannot be represented as static strings. My current approach is to loop through an array containing the 21 patterns over and over again, do an if (preg_match()) and reduce the source string match by match. In principle this works really good. However, for a 1000 lines CSS string this takes something between 2 and 8 seconds, which is too much for my project. Now I'm banging my head how other parsers tokenize and parse CSS in fractions of seconds. OK, C is always faster than PHP, but nonetheless, are there any obvious D'Oh! s that I fell into? I made some optimizations, like checking for '@', '#' or '"' as the first char of the remaining string and applying only the relevant regexp then, but this hadn't brought any great performance boosts. My code (snippet) so far: $TOKENS = array( 'IDENT' => '...regexp...', 'ATKEYWORD' => '@...regexp...', 'String' => '"...regexp..."|\'...regexp...\'', //... ); $string = '...CSS source string...'; $stream = array(); // we reduce $string token by token while ($string != '') { $string = ltrim($string, " \t\r\n\f"); // unconsumed whitespace at the // start is insignificant but doing a trim reduces exec time by 25% $matches = array(); // loop through all possible tokens foreach ($TOKENS as $t => $p) { // The '&' is used as delimiter, because it isn't used anywhere in // the token regexps if (preg_match('&^'.$p.'&Su', $string, $matches)) { $stream[] = array($t, $matches[0]); $string = substr($string, strlen($matches[0])); // Yay! We found one that matches! continue 2; } } // if we come here, we have a syntax error and handle it somehow } // result: an array $stream consisting of arrays with // 0 => type of token // 1 => token content

  • Getting XML data from a external page and parsing it with PHP

    - by James P
    I'm trying to create a database of World of Warcraft gems. If I go to this page: http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items And go to View Source in Firefox, I see a tonne of XML data which is exactly what I want. I wrote up this quick script to try and parse some of it: <?php $gemUrls = array( 'Blue' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=blue&searchType=items', 'Red' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=red&searchType=items', 'Yellow' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=yellow&searchType=items', 'Meta' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=meta&searchType=items', 'Green' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=green&searchType=items', 'Orange' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=orange&searchType=items', 'Purple' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items', 'Prismatic' => 'http://www.wowarmory.com/search.xml?fl[source]=all&fl[type]=gems&fl[subTp]=purple&searchType=items' ); // Get blue gems $blueGems = file_get_contents($gemUrls['Blue']); $xml = new SimpleXMLElement($blueGems); echo $xml->items[0]->item; ?> But I get a load of errors like this: Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: Entity: line 20: parser error : xmlParseEntityRef: no name in C:\xampp\htdocs\WoW\index.php on line 19 Warning: SimpleXMLElement::__construct() [simplexmlelement.--construct]: if(Browser.iphone && Number(getcookie2("mobIntPageVisits")) < 3 && getcookie2( in C:\xampp\htdocs\WoW\index.php on line 19 I'm not sure what's wrong. I think file_get_contents() is bringing back data that isn't XML, maybe some Javascript files judging by the iPhone parts in the errors. Is there any way to just get back the XML from that page? Without any HTML or anything? Thanks :)

  • Fetching custom Authorization header from incoming PHP request

    - by jpatokal
    So I'm trying to parse an incoming request in PHP which has the following header set: Authorization: Custom Username Simple question: how on earth do I get my hands on it? If it was Authorization: Basic, I could get the username from $_SERVER["PHP_AUTH_USER"]. If it was X-Custom-Authorization: Username, I could get the username from $_SERVER["HTTP_X_CUSTOM_AUTHORIZATION"]. But neither of these are set by a custom Authorization, var_dump($_SERVER) reveals no mention of the header (in particular, AUTH_TYPE is missing), and PHP5 functions like get_headers() only work on responses to outgoing requests. I'm running PHP 5 on Apache with an out-of-the box Ubuntu install.
