  • CodeIgniter Third party class not loading

    - by Jatin Soni
    I am trying to implement Dashboard widget class (found here: http://harpanet.com/programming/php/codeigniter/dashboard/index#installation) but it is giving me error Unable to load the requested class I have tried to add this class in autoload as well as menually to my controller $this->load->library('dash') but this also giving the same error.

  • Website redirect during maintenece but still with testing acces

    - by jme
    I have an online store that i have recently re-written most of and would like to upload it to my server. While the maintenance is taking place, i would like to redirect all visitors to an "under construction" page. (easily done with php or apache htacess etc...) The issue is that I would like to test everything when i upload it so i still need access while blocking everyone else. I was thinking some php page that is open to all with a cookie flag i could set for just myself? What is the best way to do this? Thanks jme

  • mod rewrite, title slugs and htaccess

    - by chris
    I have been taken in to provide some seo guidance on a website which has been running since 2005. My problem is i want to use clean urls. The code that handles the url is hidden away in some class file.. and with over a few thousand lines of code its a struggle to rewrite it. So I'm think, I have gone through all the products and created a slug for them as a field in the product table. Is it possible to do something like an intermediate file for htaccess. Some thing like 1./clean-slug-comes-in/ 2.htaccess catches this and uses slug.php to find the relevant product id for the slug. 3.Then product.php?id=(ID.found.from.2) is loaded?

  • [Disallow: /index.php] seems to block /my-beautiful-sef-url-123

    - by Jaroslav Záruba
    Hello I have robots.txt that looks like this: User-agent: * Disallow: /system/ Disallow: /admin/ Disallow: /index.php The obvious goal has been to prevent all the ugly URLs from being indexed, as they all begin with "/index.php". But for some reason all URLs like /my-beautiful-sef-url-123 are listed under Crawl errors in Google Webmaster Tools with "URL restricted by robots.txt". (When I test such URL it yields Allowed for both Googlebot and Googlebot-Mobile.) Can anyone help please?

  • Creating a Dynamic Image using Friends pictures

    - by Narendra Rajput
    I am working on a Facebook for which I need to get all the Profile Pictures of Friends of the users. Which I did using FQL query. I need these images for creating a poster of all the Friends Profile pics along tags in them. For that I need to create a Dynamic poster for every user with their Friends tagged in them.

  • jQuery works in FF but not in Safari

    - by Hristo
    I have some event handlers that work in FF and not in Safari. Simply put, I have a list of friends, some hard-coded, some pulled in from a database. Clicking on a buddy opens a chat window... this is much like the Facebook chat system. So in Firefox, everything works normally and as expected. In Safari, clicking on buddies that are hard-coded works fine, but clicking on buddies that are pulled in from the database doesn't pull up the chat window. <script type="text/javascript" src="js/jQuery.js"></script> <script type="text/javascript" src="js/chat.js"></script> <script type="text/javascript" src="js/ChatBar.js"></script> <script type="text/javascript" src="js/settings.js"></script> <script type="text/javascript"> var chat = new Chat(); var from = <?php echo "'" .$_SESSION['userid'] . "'"; ?>; chat.getUsers(<?php echo "'" .$_SESSION['userid'] . "'"; ?>); </script> So I load all my buddies with chat.getUsers. That function is: // get list of friends function getBuddyList(userName) { userNameID = userName; $.ajax({ type: "GET", url: "buddyList.php", data: { 'userName': userName, 'current': numOfUsers }, dataType: "json", cache: false, success: function(data) { if (numOfUsers != data.numOfUsers) { numOfUsers = data.numOfUsers; var list = "<li><span>Agents</span></li>"; for (var i = 0; i < data.friendlist.length; i++) { list += "<li><a class=\"buddy\" href=\"#\"><img alt=\"\" src=\"images/chat-thumb.gif\">"+ data.friendlist[i] +"</a></li>"; } $('#friend-list ul').append($(list)); } setTimeout('getBuddyList(userNameID)', 1000); } }); } buddyList.php just pulls in the Users from the database and returns an array with the user names. So the jQuery for clicking a buddy is: // click on buddy in #friends-panel $('#friends-panel a.buddy').click(function() { alert("Loaded"); // close #friends-panel $('.subpanel').hide(); $('#friends-panel a.chat').removeClass('active'); // if a chat window is already active, close it and deactivate $('#mainpanel li[class="active-buddy-tab"] div').not('#chat-box').removeAttr('id'); $('#mainpanel li[class="active-buddy-tab"]').removeClass('active-buddy-tab').addClass('buddy-tab'); // create active buddy chat window $('#mainpanel').append('<li class="active-buddy-tab"><a class="buddy-tab" href="#"></a><div id="chat-window"><h3><p id="to"></p></h3></div></li>'); // create name and close/minimize buttons $('.active-buddy-tab div h3 p#to').text($(this).text()); $('.active-buddy-tab div h3').append('<span class="close"> X </span><span class="minimize"> &ndash; </span>'); $('.active-buddy-tab').append('<span class="close"> X </span>'); // create chat area $('.active-buddy-tab div').append('<div id="chat-box"></div><form id="chat-message"><textarea id="message" maxlength="100"></textarea></form>'); // put curser in chat window $('.active-buddy-tab #message').focus(); // create a chat relationship return false; }); ... and the basic structure of the HTML is: <div id="footpanel"> <ul id="mainpanel"> <li id="friends-panel"> <a href="#" class="chat">Friends (<strong>18</strong>) </a> <div id="friend-list" class="subpanel"> <h3><span> &ndash; </span>Friends Online</h3> <ul> <li><span>Family Members</span></li> <!-- Hard coded buddies --> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend 1</a></li> <li><a href="#" class="buddy"><img src="images/chat-thumb.gif" alt="" /> Your Friend </a></li> <!-- buddies will be added in dynamically here --> </ul> </div> </li> </ul> </div> I'm not too sure where to begin solving this issue. I thought it might be a rendering bug or something with the DOM but I've been staring at this code all day and I'm stuck. Any ideas on why it works in FF and not in Safari? btw... I'm testing on Snow Leopard. Thanks, Hristo

  • Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML

    - by phpwns
    Anyone have a good solution for scraping the HTML source of a page with content (in this case, HTML tables) generated with Javascript? An embarrassingly simple, though workable solution using Crowbar: <?php function get_html($url) // $url must be urlencode(d) { $context = stream_context_create(array( 'http' => array('timeout' => 120) // HTTP timeout in seconds )); $html = substr(file_get_contents('http://127.0.0.1:10000/?url=' . $url . '&delay=3000&view=browser', 0, $context), 730, -32); // substr removes HTML from the Crowbar web service, returning only the $url HTML return $html; } ?> The advantage to using Crowbar is that the tables will be rendered (and accessible) thanks to the headless mozilla-based browser. The problem, of course, is being dependent on on an external web service, especially given that SIMILE seems to undergo regular server maintenance. :( A pure php solution would be nice, but any functional (and reliable) alternatives would be great.

  • Reading the Set-Cookie instructions in an HTTP Response header

    - by Eduardo León
    Is there any standard means in PHP to read the Set-Cookie instructions in an HTTP Response header, without manually parsing it? More specifically, I want to read the value of the ASP.NET_SessionId cookie returned by an ASP.NET Web Service I am consuming. EDIT: I am consuming the Web Service using PHP's native SoapClient class. I can use the __getLastResponseHeaders() method to retrieve the whole of the HTTP response header returned by the Web Service: HTTP/1.1 200 OK Cache-Control: private, max-age=0 Content-Type: text/xml; charset=utf-8 Server: Microsoft-IIS/7.5 Set-Cookie: ASP.NET_SessionId=ku501l55o300ik3sa2gu3vzj; path=/; HttpOnly X-AspNet-Version: 2.0.50727 X-Powered-By: ASP.NET Date: Tue, 11 Jan 2011 23:34:02 GMT Content-Length: 368 But I want to extract the value of the ASP.NET_SessionID cookie: ku501l55o300ik3sa2gu3vzj And, of course, I don't want to do it manually.

  • scanf formatting issue

    - by da_rockwilder
    I have a log file with the following format: INFO 2011-03-09 10:26:15,270 [user] message I want to parse the log file using PHP: // assume file exists and all that $handle = fopen("log_file.txt", "r"); while ($line_data = fscanf($handle, "%s %s %s [%s] %s\n")) { var_dump($line_data); } fclose($handle); When I run this code I get: [0]=> array(5) { [0]=> string(4) "INFO" [1]=> string(10) "2011-03-09" [2]=> string(12) "10:26:15,270" [3]=> string(5) "user]" [4]=> NULL } // snip It appears the closing bracket in the format string ("%s %s %s [%s] %s") is disrupting the rest of the line from getting parsed. I checked the PHP docs for scanf (as suggested by fscanf), and I didn't see anything mentioning having to escape a left bracket. Any suggestions on how to get the 4th and 5th elements to look like "user" and "message" respectively?

  • why won't my ajax work asynchronously

    - by payling
    I'm having trouble understanding why my code will not work asynchronously. When running asynchronously the get_price.php always receives the same $_GET value even though the alert before outputs a unique $_GET value. var arraySize = "<? echo count($_SESSION['items']); ?>"; //get items count var pos = 0; var pid; var qty; getPriceAjax(); function getPriceAjax() { pid = document.cartItemForm.elements[pos].id; //product id qty = document.cartItemForm.elements[pos].value; //quantity alert('Product: ' + pid + ' Quantity: ' + qty); $.ajax({ url:"includes/ajax_php/get_price.php", type:"GET", data:'pid='+pid+'&qty='+qty, async:true, cache:false, success:function(data){ while(pos < arraySize) { document.getElementById(pid + 'result').innerHTML=data; pos++; getPriceAjax(); } } }) }

  • Question regarding Ajax Hacking

    - by Vincent
    All, I have a PHP website written in Zend Framework and MVC. Most of the controller actions check if the request is an Ajax request or not, else they redirect the user to home page. I am thinking about various ways to break that site. I am considering the following scenario: A user creates his own PHP project on his Local machine. User writes a JQuery ajax post request to one of the controllers on my site and tries to post malicious info. Ex: $.ajax({ type: 'POST', url: "https://marketsite/getinfo/getstuff", cache: false, dataType: "html", success: function(html_response){ alert(html_response); }, error: function(xhr,ajaxOptions,errorThrown){ alert(errorThrown); } }); My Question is does "url" attribute in the ajax request above take absolute path? I know it takes relative path. Also, is it possible to break any site by sending such requests? Thanks

  • jQuery getting these functions to work together

    - by brett
    I'm new to jQuery and have tried looking around for an answer on how to do this. I have 2 functions and I would like both to work together. The one function is submitHandler and its used to hide a form and at the same time add a class to a hidden element to unhide it - ie a thank you for submitting h1. The other function is to grab the input data and display it onsubmit in the form. So the problem is that I can get that one to work but then the other doesnt. Ie on form submit I can see the data input but not the h1 Thank you message. Here are the functions: SubmitHandler: submitHandler: function() { $("#content").empty(); $("#content").append( "<p>If you want to be kept in the loop...</p>" + "<p>Or you can contact...</p>" ); $('h1.success_').removeClass('success_').addClass('success_form'); $('#contactform').hide(); }, onsubmit="return inputdata()" function inputdata(){ var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; return true; }, The form uses PHP and jQuery - I dont know about AJAX but after some reading even less sure. Please help me out I dont know what I'm doing and at the moment I am learning but its a long road for me still. Thank you The form: <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contactform" onsubmit="return inputdata()"> <div class="_required"><p class="label_left">Name*</p><input type="text" size="50" name="contactname" id="contactname" value="" class="required" /></div><br/><br/> <div class="_required"><p class="label_left">E-mail address*</p><input type="text" size="50" name="email" id="email" value="" class="required email" /></div><br/><br/> <p class="label_left">Message</p><textarea rows="5" cols="50" name="message" id="message" class="required"></textarea><br/> <input type="submit" value="submit" name="submit" id="submit" /> </form> The PHP bit: <?php $subject = "Website Contact Form Enquiry"; //If the form is submitted if(isset($_POST['submit'])) { //Check to make sure that the name field is not empty if(trim($_POST['contactname']) == '') { $hasError = true; } else { $name = trim($_POST['contactname']); } //Check to make sure sure that a valid email address is submitted if(trim($_POST['email']) == '') { $hasError = true; } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) { $hasError = true; } else { $email = trim($_POST['email']); } //Check to make sure comments were entered if(trim($_POST['message']) == '') { $hasError = true; } else { if(function_exists('stripslashes')) { $comments = stripslashes(trim($_POST['message'])); } else { $comments = trim($_POST['message']); } } //If there is no error, send the email if(!isset($hasError)) { $emailTo = '[email protected]'; //Put your own email address here $body = "Name: $name \n\nEmail: $email \n\nComments:\n $comments"; $headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email; mail($emailTo, $subject, $body, $headers); $emailSent = true; } } ? The Jquery Validate bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, Here is the full jQuery bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, submitHandler: function() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, }); }); Latest edit - Looks like this: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, function submitHandler() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, function inputdata() { var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; }, $(document).ready(function(){ $('#contactForm').submit(function() { inputdata(); submitHandler(); }); }); });

    What's the best practice in a secure manner to setup the user/group and permissions? Here's what we currently have; web server runs as www/www. Fastcgi Php runs as www/www. User's shell/ftp account is username/username. We want the user to be able to have full access to all files, including those created by the web server 'www' from the shell or ftp. Similarly, we want the scripts run by fastcgi/php to be able to create files in user created directories and modify user created files.

  • POST data disapearing on large file upload

    - by DfKimera
    I'm having issues with a file uploading utility in my PHP application. When sending large files (9MB+) over the form, I get a very odd behaviour: the POST data I've included in the form dissapears, including the file information. I've already increased all PHP limits I could (time limit, max input time, post max size, memory limit and upload max filesize) and I still can't get the proper behaviour. I've tried replacing the regular HTTP forms with a Flash-based solution (SWFUpload, www.swfupload.org), still the same behaviour. I've tried multiple files of similar sizes and its definitely not a particular file issue. I've debugged the POST vars sent using Firebug, and the correct variables are still there in the header, together with the file. What could be going on here?

  • Default controller name is removed on browser refresh (CodeigniterPHP/Nginx issue?)

    - by tim peterson
    For all pages in my codeigniter app except my default controller, when I refresh the browser the url isn't affected as one would expect. However for my default controller, main.php, when when I refresh the browser at "http://localhost/main" or "http://mysite.com/main", the main part is stripped off the url. So the browser bar shows just "http://localhost" or "http://mysite.com". Totally lost on where to start with this but was just wondering if anyone has come across this before...? Here's what I think could be the relevant part of my nginx.conf (if Nginx is the problem). if ($request_uri ~* ^(/main(/index)?|/index(.php)?)/?$) { rewrite ^(.*)$ / permanent; }

  • using jquery to load data from mysql database

    - by Ieyasu Sawada
    I'm currently using jquery's ajax feature or whatever they call it. To load data from mysql database. Its working fine, but one of the built in features of this one is to load all the data which is on the database when you press on backspace and there's no character left on the text box. Here's my query: SELECT * FROM prod_table WHERE QTYHAND>0 AND PRODUCT LIKE '$prod%' OR P_DESC LIKE '$desc%' OR CATEGORY LIKE '$cat%' As you can see I only want to load the products which has greater than 0 quantity on hand. I'm using this code to communicate to the php file which has the query on it: $('#inp').keyup(function(){ var inpval=$('#inp').val(); $.ajax({ type: 'POST', data: ({p : inpval}), url: 'querys.php', success: function(data) { $('.result').html(data); } }); }); Is it possible to also filter the data that it outputs so that when I press on backspace and there's no character left. The only products that's going to display are those with greater than 0 quantity?

  • Does HTML5 make Javascript gaming safer (more secure)?

    - by Sean Madigan
    I know that Javascript is an incredibly unsecure way of programming a persistent game, where for instance you are doing battle calculations in an RPG and then award XP through linking to a PHP page when they win that adds XP to a database (since the player could make their own javascript to always win or just look at the PHP page that you get sent to when you win and just go there anyway). So with that said, I'm wondering if HTML5 makes multiplayer/persistent games any safer in this regard, since I know it still uses Javascript. Or am I still doomed to rely entirely on server-side scripting for doing any calculations that award the player?

  • MySQL: Efficient Blobbing?

    - by feklee
    I'm dealing with blobs of up to - I estimate - about 100 kilo bytes in size. The data is compressed already. Storage engine: InnoDB on MySQL 5.1 Frontend: PHP (Symfony with Propel ORM) Some questions: I've read somewhere that it's not good to update blobs, because it leads to reallocation, fragmentation, and thus bad performance. Is that true? Any reference on this? Initially the blobs get constructed by appending data chunks. Each chunk is up to 16 kilo bytes in size. Is it more efficient to use a separate chunk table instead, for example with fields as below? parent_id, position, chunk Then, to get the entire blob, one would do something like: SELECT GROUP_CONCAT(chunk ORDER BY position) FROM chunks WHERE parent_id = 187 The result would be used in a PHP script. Is there any difference between the types of blobs, aside from the size needed for meta data, which should be negligible.
