PHP - Php Failing On Large Image File Upload

I've got a basic form for users on the site to fill out a form and upload a single image which is resized and saved to a directory on the server. I've tried the form numerous times and with images usually under 1MB the form successfully submits, data is queried and the image uploaded is resized and saved. However, recently I tried uploading larger sized images (1.2mb, 2.4mb, 3mb) and the script would seem to break. It wouldn't query any information, save any images, etc.

If you check my code attached, I have errors ready to output at all levels and not even any errors show up. When I hit submit after attempting to upload a larger file usually over 1MB, the page refreshes back to PHP_SELF as if it submitted but returns absolutely no message, alert or error and the form which was on the page is now gone.

I checked my PHP.ini file and my max file size upload is set at 32mb. Is there anything else with file size restrictions that I could be missing that is allowing this script to crash without even sending me any errors?

Hello All,

I have a simple upload form which I am using to upload files to Box.net using PHP Curl. It works fine for small files, but times out for larger files. Anyone have any suggestions for this?

Thanks,
Pete

Hello everyone, I'm new here   My website was working fine until a few days ago, Up until then my str_replace('s130x130', 's800x800') and str_replace('_s', '_o') solved the picture thing. Now the images are broken (or very small) and I can find no documentation on how to enlarge the pictures. Thus my question: how do I retrieve larger pictures from the Facebook PHP SDK? Code

foreach($pagefeed['data'] as $post) {
if ($post['type'] == 'status' || $post['type'] == 'link' || $post['type'] == 'photo') {
if ($post['type'] == 'photo') {
echo "<div class='col-md-6 col-sm-6'>";
echo "<div class='thumbnail'>";
echo "<img src=" . str_replace('s130x130', 's800x800',
str_replace('_s', '_o', $post['picture'])) . " />";
echo "<div class='caption'>";
echo "<sup>Geplaatst op: " . date("d-m-Y, (strtotime($post['created_time']))) . "</sup>";

if (empty($post['message']) === false) {
echo "<p><span class='glyphicon glyphicon-comment'></span> " . $post['message'] . "</p>";}

echo "</div>";
echo "</div>";
echo "</div>";
$i++;
}
}
}

Thanks in advance!

I have a flash application that calls php script to do the image file upload and save the image in jpg format in thumbnail size. I swear it worked at one time, and then as I tried to figure out how to covert other image formats that are not currently built-in in php library (createimagefrom... functions), I played around with it a little bit, then it doesn't upload file any more!!! What I got, is that NONE of the image files is saved in my designated image folders, subsequently the flash application comes up with a broken image link.  PLEASE HELP! MANY THANKS!

Here's the relevant flash code:
Code: [Select]
private function uploadFiles():void
{
var curTime:Date = new Date();
timeStamp = curTime.valueOf().toString();
var variables:URLVariables = new URLVariables("timeStamp=" + timeStamp);

  var request:URLRequest = new URLRequest(ModelLocator.getInstance().serverPath+"uploadArtImages.php");
request.method = URLRequestMethod.POST;
request.data = variables;
file.upload(request);
  Application.application.showLoading();
}
Here's my php script: (it's really a simple script, a big chunk of it is just some functions that does error checking and image conversions)

Hi I am new to PHP...
I wanted to design a banner.. the require data should be entered by user like Name of a banner, Details as well as Image to display on it.

I think for this I may need to use file upload option.. I tried this but $Files not working for me... some times its shows diff errors on diff browsers, I am new to PHP I dont know what is the prob.

I dont have any code on this... if anyone have any tutorial on this, that will be the gr8 help as I am trying to solve this from last 1 and 1/2 week..

I used http://www.tizag.com/phpT/fileupload.php
its showing error msg There was an error uploading the file, please try again!

Thanks in adavnce
