Cannot upload .mpg files - php

Question

I've built a rather straightforward file uploader in PHP. So far I've had no troubles uploading images and zip files. However, I can't seem to upload .mpg's. Whenever I try then it after hanging for a moment the page seems like it didn't try to upload anything at all. For example: this
// This is also manually set in php.ini
ini_set("upload_max_filesize", "524288000");
...
print_r($_FILES);
print_r($_POST); // I'm sending along one variable in addition to the file
returns nothing but empty arrays. For completeness, here's the front-end
<form action="uploadVideo.php" method="post" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="524288000"/>
<input type="hidden" name="extravar" value="value" />
<p>
<label for="file">Filename:</label>
<input type="file" name="file" id="file" /><br />
<i>Accepted formats: .mp4, .3gp, .wmv, .mpeg and .mpg. Cannot exceed 500MB.</i>
</p>
<p>Description:</p>
<textarea name="description" rows="4" cols="40"></textarea>
<p><input type="submit" name="submit" value="Submit" /></p>
</form>
The file I am testing with is only 33MB and I tested a .wmv of similar size and it uploaded just fine.

Answer 1

You cannot adjust the file upload limits using ini_set() from within the script that the uploads go to - the script does not get executed until after the upload is completed, so the ini_set() overrides cannot take place. The default parameters in PHP will be in place with the lower limit, and will kill the upload if it exceeds the system upload_max_filesize.
You need to override at the .ini level in PHP, or via a php_value directive in a .htaccess file. Those will change PHP's settings as the upload starts.

Ok, the first thing i thougt would be a problem with the filesize but other files with this size are working as you wrote.
But just do get shure it isn't a file size problem:
When you rise the max filesize you hmust also rise the max post size: post_max_size
