Renaming the extension of php to jpg  new!
by vandall, 15 years, 3 months ago
Hi!
Code:
$foo = new upload($_FILES['fileToUpload']);
$foo->allowed = array('image/jpg','image/png',
                      'image/gif','image/jpeg');
$foo->forbidden = array('application/*');
$foo->file_new_name_body = $filename;
$foo->image_convert = jpg;
$foo->image_resize          = true;
$foo->image_ratio_crop      = 'C';
$foo->image_x = 200;
$foo->image_y = 200;
$foo->Process('../img/users/200/');
Objective: To enable the user to upload a picture of a particular type.
If the script is "php", change the extension for example "JPG", he downloads.

How to get rid of this? thanksReply

Can you copy here the logs produced by the class, using version 0.28?Reply

may be something with the settings?Reply

Check your installation of PHP. You can see what extensions are loaded in the php.ini file. (Note that I cannot support the class on Windows).

Your system is unable to find out the MIME type of the file, so it cannot block a malicious file. Besides, you may have open_basedir enabled.Reply

I actually use it on Windows.

Thank you for your help!Reply
