I have a little upload script which works fine in IE..
but in Firefox I get this error:
The image "http://localhost/ruils/upload.php" cannot be displayed because it contains errors.
But the image gets uploaded fine
Plus if I echo this at the top of the upload.php script:
echo '<pre>';
print_r($_FILES);
echo '</pre>';
...then Firefox displays the expected info, throws no errors and uploads the image correctly.
But of course you're not meant to echo anything when setting Headers - which I do as I'm rescaling the jpeg on upload
(twice - once to a reasonable size, second to a thumb size)
the error is nothing to do with IE's filetype of image/pjpeg as that's taken into account
any ideas anyone?
here's the entire upload script:
<?php
$userfile = $FILES['userfile']['tmp_name'];
$userfile_name = $FILES['userfile']['name'];
$userfile_size = $FILES['userfile']['size'];
$userfile_type = $FILES['userfile']['type'];
$userfile_error = $FILES['userfile']['error'];
if ($userfile_error > 0)
{echo "Error: ";
switch ($userfile_error)
{case 1: echo "File exceeded upload_max_filesize"; break;
case 2: echo "File exceeded max_file_size"; break;
case 3: echo "File only partially uploaded"; break;
case 4: echo "No file uploaded"; break;
}
echo "<br><a href='javascript:history.back()'><img src='images/back.gif' border='0'> Back </a>";
exit;}
// does file have the right MIME type?
if ($FILES['userfile']['type']=='image/jpeg' || $FILES['userfile']['type']=='image/pjpeg')
{ $userfile_name=(str_replace('.jpg','',$userfile_name));
$userfile_name=(str_replace('.JPG','',$userfile_name));
$userfile_name=$userfile_name.'.jpg';
