Restrict uploads to specified file types only, jpg, gif

wordpress snippet

Adding this snippet to the functions.php of your wordpress theme will allow you to restrict uploads to an array of specified mime types only. This sample only allows jpg and gif images, adding a new line for png eg: ‘png’ => ‘image/png’, would then allow png images.

( example screenshot )
snippet :  PHPcopy
add_filter('upload_mimes','restrict_mime'); 
function restrict_mime($mimes) { 
$mimes = array( 
                'jpg|jpeg|jpe' => 'image/jpeg', 
                'gif' => 'image/gif', 
);
return $mimes;
}

    How would you set restriction parameters for non-image file types like PDFs? Thanks!

      Hi Rone, you should be able to just add a new line after line 05

      ‘gif’ => ‘image/gif’,
      ‘pdf’ => ‘application/pdf’,

      that should do it just copy the line and paste it in.
