PHP - Image Handler/ajax Problems
Hi guys, first time on forum, and in desperate need of help. I asked my co workers and they don't have a single clue into what is going wrong.
I built a PHP image handler to secure images down to the user too see. When I integrate this into the ajax however, the images only load on the page after all the ajax requests finish. In this case there are 4 ajax requests. I have attached screenshots of the problem before all the ajax requests finish and after. NOTE: This works fine with images that are not being generated PHP. At first I thought it might be a header problem with the image handler but I cant seem to find any people who have seen this problem. Here is the code. class SecureImage { public $user_img_dir; public $db_img_dir; public $temp_img_dir; public $main_img_dir; function __construct(){ global $SESSION; //set the class vars $this->temp_img_dir = BASE_PATH.'webdocs/images/_temp/'; $this->main_img_dir = '/var/images/'; //now check to see if there is a directory for this file //build the directory for the image $user_id = $SESSION->getUserid(); $db_name = $GLOBALS['Config']->db['db_name']; $user_img_dir = "{$this->main_img_dir}{$db_name}/{$user_id}/"; $db_img_dir = $this->main_img_dir.$db_name."/"; //set the class vars $this->user_img_dir = $user_img_dir; $this->db_img_dir = $db_img_dir; //now check to see if the directory is there if(!is_dir($user_img_dir)){ //check to see if the db_name is a dir if(!is_dir($db_img_dir)){ //make the directory mkdir($db_img_dir); } //now make the user id dir mkdir($user_img_dir); } } public function getImage($img){ $img_array = explode('.', $img); switch($img_array[1]){ case 'jpg': case 'jpeg': header('Content-Type: image/jpeg'); break; case 'png': header('Content-Type: image/png'); break; case 'gif': header('Content-Type: image/gif'); break; } header('Content-Disposition: inline;'); //get the file size $img_size = filesize($this->user_img_dir.$img); header('Content-Length: '.$img_size); echo readfile($this->user_img_dir.$img); } } If anyone has any ideas, much appreciated. Similar TutorialsNow I'm having this strange issue with my website I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it. The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page. <?php $q=$_GET["q"]; include'../config/connection.php'; $result = mysql_query("SELECT * FROM applications WHERE id = '$q'"); echo "<center><table border='1'> <tr> <th>Account Name</th> <th>Character Name</th> <th>Gender</th> <th>Skin Color</th> </tr>"; $row = mysql_fetch_array($result); echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['charactername'] . "</td>"; echo "<td>" . $row['gender'] . "</td>"; echo "<td>" . $row['race'] . "</td>"; echo "</tr></table></center>"; echo"<br/>"; echo"<table><tr> <th>Description</th> <th>Metagaming</th> <th>Powergaming</th></tr>"; echo"<tr>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>"; echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>"; echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>"; echo"<input type='submit' name='answer' value='Accept' /><a/>"; echo"<input type='submit' name='answer' value='Decline' /></center>"; echo"<input type='hidden' name='id' value='$q'/>"; echo"</form></table>"; ?> Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that. <? if(!empty($_POST['why'])) { $why = mysql_real_escape_string($_POST['why']); $answer = trim($_POST['answer']); $id = $_POST['id']; if($answer == "Accept") { $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'"); echo"Successfully accepted"; $answer = 1; } elseif($answer == "Decline") { echo"Successfully declined"; $answer = 0; } $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error()); if($query) { echo"<br/>Query went through without problems"; header("Refresh: 5;url=index.php?page=tester"); } } ?> This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications Code: [Select] <script type="text/javascript"> function showApplication(str) { if (str==""||str==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","tester/applications.php?q="+str,true); xmlhttp.send(); } </script>If you need any more information feel free to ask for it. Thanks in advance. I found this code online, it works fine but i dont know where i should put the SQL statement to place the image path onto my database. Here is what i have...the SQL statement i place them at doesnt work. Any suggestions? <?php function resizeImg($arr){ //you can change the name of the file here $date = md5(time()); //////////// upload image and resize $uploaddir = $arr['uploaddir']; $tempdir = $arr['tempdir']; $temp_name = $_FILES['photo']['tmp_name']; //echo $temp_name; $img_parts = pathinfo($_FILES['photo']['name']); $new_name = strtolower($date.'.'.$img_parts['extension']); $ext = strtolower($img_parts['extension']); $allowed_ext = array('gif','jpg','jpeg','png'); if(!in_array($ext,$allowed_ext)){ echo '<p class="uperror">Please upload again.

Ultimate Aim: To upload multiple images using ajax using a PHP script which will be fired once an image is selected and then return the resulting URL for use in rest of my JS http://peter-gosling...hooseimage.html simple form posts to http://peter-gosling...d/saveimage.php This PHP script below currently gets the posted image and assigns it a random number file name and echos this
<?php

$urlpath = "http://www.peter-gosling.co.uk/testupload/images/";
$temp = explode(".",$_FILES["userfile"]["name"]);
$newfilename = rand(1,999999999) . '.' .end($temp);
$newuploadfile = $uploaddir . $newfilename;
echo "<p>";

Two common suggestions are the bounce handler at http://www.phpclasses.org/package/2691-PHP-Parse-bounced-e-mail-message-reports.html , or the PHP Mailer-BMH, http://phpmailer.worxware.com/index.php?pg=bmh . I know for certain that PHP Mailer-BMH is dated and no longer a viable solution, and I believe the PHP classes solution is also dated. Does anyone know of a current bounce mail handler? Preferably it would include the functionality to connect to a remote mailbox so I won't have to do this myself. Thanks for any help. I have a click handler that is causing some problem. I am using hammer.js for a slider.
This is the link http://ingrub.com/iphone/
When you hit the last slide the text of next changes to let's grub, but the problem is that if you swipe back to an earlier screen and you try to go next it automatically goes to the link instead of going to the next slide these are some of the functions that i am using
this.showPane = function(index, animate) {
// between the bounds
index = Math.max(0, Math.min(index, pane_count-1));
current_pane = index;
var offset = -((100/pane_count)*current_pane);
setContainerOffset(offset, animate);
if(current_pane == 2){
$(".next2").text("Let's Grub");
$(".navigation2").addClass('linkMe');
} else {
$(".next2").text("Next");
$(".navigation2").removeClass('linkMe');
}
};
$( ".next2" ).click(function() {
carousel.next();
$('.linkMe').click(function() {
window.location = "discover.html";
});
return false;
});
I am not sure what to do to fix this bug.
This topic has been moved to JavaScript Help. http://www.phpfreaks.com/forums/index.php?topic=358574.0 Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?

I can't get the reg. form handler to recognize the $conn variable from the config.php file. if I add require '../../config/config.php'; to it I get this error:
Warning: require(../../config/config.php): failed to open stream: No such file or directory in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 3 I don't know why it can't find that file, but the way I understand PHP is that I don't need that line because it's in the register.php. When I don't use it I get a party of errors all connected to it not recognizing the $conn variable:
Notice: Undefined variable: conn in /opt/lampp/htdocs/qcicnews/includes/form_handlers/register.php on line 43
There's about 6 more that look like the ones above but from different lines where $conn is referenced, I just deleted them for brevity sake. I'm pretty new to PHP and this is the most difficult situation I've encountered so far, can someone help me find the way here?
Good Day, I'm using the following example script from http://php.net/manual/en/function.session-set-save-handler.php which I have placed in session-handler.php and is included at the top of my index.php file. I have multiple domain names for the same website, so naturally when a person logs into the site, I would like the session to be active across all the domains instead of them having to login again if say they go from mysite.com to mysite2.com. session-handler.php <?php function open($save_path, $session_name) { global $sess_save_path; $sess_save_path = $save_path; return(true); } function close() { return(true); } function read($id) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; return (string) @file_get_contents($sess_file); } function write($id, $sess_data) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; if ($fp = @fopen($sess_file, "w")) { $return = fwrite($fp, $sess_data); fclose($fp); return $return; } else { return(false); } } function destroy($id) { global $sess_save_path; $sess_file = "$sess_save_path/sess_$id"; return(@unlink($sess_file)); } function gc($maxlifetime) { global $sess_save_path; foreach (glob("$sess_save_path/sess_*") as $filename) { if (filemtime($filename) + $maxlifetime < time()) { @unlink($filename); } } return true; } session_set_save_handler("open", "close", "read", "write", "destroy", "gc"); session_start(); ?> The script above doesn't appear to be throwing any errors, and I can login like normal but it doesn't seem to be saving the sessions at all. So I still have to login to each separate domain. Any ideas? Thanks, Ace Here's a very interesting conundrum that I think will stump quite a few of you. Here's the setup: I was put in charge of the project of maintaining and developing a database application for one of my company's customers. The application has been evolving ever since. One of the more recent changes we've been working on is to add file upload functionality to catalog forms, letters, etc. I had this application working before by uploading the file directly to the server, giving it a random name, putting it in a /forms directory, and entering a hyperlink in a log line, which was then entered into the MySQL database. It's a pretty straightforward procedure. BUT my customer doesn't always have net access so he has a laptop running the application with its own MySQL and PHP installation, and he has a script that synchronizes the database with the one on our server. Not very practical or efficient, I know, but I inherited this project and had no choice in the matter. Since the client needs to upload and catalog files, and needs those files to be in sync with our server, I figured instead of just having a folder full of files that also has to be synched, why not throw binary data into the database and have the files in the database? Well I quickly developed a set of scripts to handle this task, and all of them worked flawlessly on our Linux server. It worked, that is, until I tried to install the same code on our client's Windows crapbox. At this point, I'd like to convey the download script that I wrote: Code: [Select] require_once('includes/application.inc.php'); if($_REQUEST['id']) { $id = mysql_real_escape_string($_REQUEST['id']); } else die("Error"); $result = mysql_fetch_assoc(mysql_query("SELECT * FROM Files WHERE id = $id")); header("Content-type: ".$result['type']); header("Content-length: ".$result['size']); header("Content-Disposition: attachment; filename=".$result['filename']); echo $result['data']; You see? Very simple and to the point. This script is called from a hyperlink elsewhere in the application, it queries for the file and downloads it. The problem is that when I'm running this download script on the laptop's Windows server, the browser echoes a \r\n as well as the binary data. As you can imagine, this wreaks havoc with files downloaded. Here's what I've determined: The data IS being stored properly in the database This only happens with certain files and not with others. The most egregious offenders are .odt files. The data is not being returned from the database corrupted. I verified this using various regex's and by dumping the data right out of the database into hex in the browser. Apache is not inserting that line break as seen by testing with static html files From these things, I have determined that PHP is the most likely culprit. My limited knowledge of the entire library of functions notwithstanding, is there anything I'm missing? Is there a more "safe" way to echo binary data? Does anyone have any sort of clue as to what could be causing this? I've scoured Google and this forum and haven't found anything. Thanks in advance for your insight. Is it possible to find out what line of code a PHP script was processing immediately before it is interrupted upon receiving a POSIX signal? A bit of background - I've got a PHP script which runs (from the command line) hundreds of thousands of times a day and usually it's just fine. Every so often (less than once a week) it gets into a muddle and freezes until I kill it. I've written a signal handler (using the posix_signal() function) into the script which catches SIGABRT signals. When it gets one, it dumps $GLOBALS to a file, cleanly releases the data its working on then exits. That gives me a nice 'get out of jail free' card, but I'd really like to identify where (and then why) it's freezing. I could insert loads of debugging code which sets some variable with what stage it's up to, but it's a fairly complicated script and I'd rather not. There's got to be a better way! __LINE__ and __FUNCTION__ unfortunately just point to my signal handler function. So, is there anyway that the function which is invoked by the SIGABRT signal can report what line of code the script was on at the time the SIGABRT was received? Or alternatively, is there a way to figure out what a running PHP script is doing if you know its PID? Maybe there's something in /proc/<PID> which might help me... I've made a custom error handler, but it doesn't seem to work the same way on the dev and prod environments. Dev is windows/xampp, and prod is a standard LAMP install. Sometimes on prod I get a blank white screen and dev shows no errors. If I remove the error handler, everything goes back to normal. Just wondering if anyone sees something wrong he Code: [Select] <?php function my_error_handler ($e_number, $e_message, $e_file, $e_line, $e_vars) { // email address to email errors to on the production environment $email_address = 'myemailaddress@gmail.com'; switch ($e_number) { case E_USER_ERROR: $error_type = 'E_USER_ERROR'; break; case E_USER_WARNING: $error_type = 'E_USER_WARNING'; break; case E_USER_NOTICE: $error_type = 'E_USER_NOTICE'; break; case E_WARNING: $error_type = 'E_WARNING'; break; case E_NOTICE: $error_type = 'E_NOTICE'; break; case E_STRICT: $error_type = 'E_STRICT'; break; default: $error_type = 'UNKNOWN ERROR TYPE'; break; } $message = '<hr />PHP ' . $error_type .

What I need to do is: File in -> "What kind of file are you? Oh! a Zip File, let's unzip and ask the same question of the contents!" -> Process contents. So basically I need to ask the same question twice, once of the zip and once of the contents of the unzipped file. This is where I'm struggling, someone told me to use a function which I tried but it kept breaking and I wasn't sure why. Therefore I have attached 2 files. 1 which currently works 99% except for "asking the question again" and one which doesn't work but I was told is the right way to do it File 1: Works 99%.

Many thanks. Hello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb I'm sure it's not much, but I'm not understanding something with custom error handlers: I've created a custom error handler, which I initially set when my page loads : set_error_handler(array ( new ErrorHandler(), 'handleError' ));
It seems to catch all internal PHP errors, such as if I: var_dump($non_existing_var); right after the set_error_handler.... Now, I have an object that throws an exception after: set_error_handler(array ( new ErrorHandler(), 'handleError' )); $locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception ... I thought that with an error handler set, I could 'skip' the try/catch for it, but doing so, PHP spits out in its internal log: PHP Fatal error: Uncaught CorbeauPerdu\i18n\LocaleException: ....
My error handler doesn't catch it at all before, thus my page breaks!! If I want it to go through the error handler, I have to init my Locale with a try/catch and use trigger_error() like so:
set_error_handler(array ( new ErrorHandler(), 'handleError' ));
try {
$locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception
}
catch(Exception $e) {
trigger_error($e->getMessage(), E_USER_ERROR);
}
...
Is this normal ? I thought one of the goals of the error_handler was to catch anything that wasn't dealt with? Thanks for your answers! As the title say, I can not for the life of me get the "$bank" content to display, no matter HOW much I try... Does anyone see any errors.
