How to restrict file uploads by extension?

Posted by Prem Tiwari | Updated on September 27, 2020

I believe you can add a filter to upload_mimes to restrict to certain types. The upload_mimes hook:

add_filter('upload_mimes','restict_mime');

function restict_mime($mimes) {

$mimes = array(

'jpg|jpeg|jpe' => 'image/jpeg',

'gif' => 'image/gif',

'png' => 'image/png',

);

return $mimes;

}
