Php Help Needed ASAP.

I was wondering do you know how to restrict the image if it does not complie with the dimensions i want to set.

<form enctype="multipart/form-data" action="uploader.php" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="10000000" />
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

Use "if" statements in the php file or add a new variable in the form.

Use something like

<input type="hidden" name "MAX_DIMENSIONS" width="100" height="100" value="MAX_IMAGE" />

and then get the php file to check the dimensions do not exceed the values above

It isn't very secure storing restrictions etc. in hidden fields, as malicious users could change these values. Your best option would be to have the restrictions stored in a variable inside your PHP script, and then checking the size of the image (http://uk.php.net/getimagesize) against the limitations you've set.

You need to do it in the PHP, not the HTML form.

Something like this:

$max_height = "100";
$max_width = "100";
if ($max_width && $max_height) {
list($width, $height, $type, $w) = getimagesize($_FILES['file']['tmp_name']);
if($width > $max_width || $height > $max_height){
print "File height and/or width are too big!";
exit;
}
}
