image upload, image type check not working

[Paul Ferrie]

I have been having problems with this for some time


$types_array = array("image/gif","image/jpeg","image/pjpeg","image/jpg","image/x-png");
//Check file against array
if (!in_array($_FILES['userfile']['type'], $types_array)) {
//Return error if file typ dosnt match array
header("Location: addImage.php?error=That file type is not allowed!");
exit;
}

It will only allow me to upload gif format. i get file type not allowed for jpg files and png files :(. Does any one have an idea why this is not working.

Cheers
Paul

Are you using firefox/netscape to upload the images? There are mime type problems with those browsers.

[Paul Ferrie]

no i am using ie

Just had a thought. What about using substr to get the last 3 characters of the filename then check the ext against an array of ext type?

All you've got to do is to check $_FILES['userfile']['type'] when you're uploading jpg file for example
echo($_FILES['userfile']['type']);
You can check uploaded file with getimagesize (http://pl2.php.net/function.getimagesize) too.

This is doing my head in :mad: :mad: :mad: :mad: :mad:
I have just tried again on a different server and still it wont work.

Try yourselfs

Image type is returned empty if i try to upload a jpg
but it works fine for gif format

[Mateusz]

Did you check getimagesize function?
Are you sure that the file is upladed properly? Can you check its size for example? Only image type is empty?

Errrh are you sure you have the right enctype? cos this code works in IE and FF:

<?php
if (isset($_POST['send'])) {
$types_array = array('image/gif', 'image/jpeg', 'image/pjpeg', 'image/jpg', 'image/x-png', 'image/png');
if (!in_array($_FILES['userfile']['type'], $types_array)) {
echo('nah not found in array<br />');
}
echo($_FILES['userfile']['type']);
}
?>
<br />
<form method="post" enctype="multipart/form-data" action="<?php echo($_SERVER['PHP_SELF']); ?>">
<input type="file" name="userfile" size="20" /><input type="submit" name="send" value="Hit It" />
</form>


Are you sure that both hosts your using supports file upload handeling through POST capabilities?
