Apparently a network quirk. I tried your code, but had to comment out the wp-ultimo is active check and the wu_has_plan() call since I don’t have those. I still had trouble uploading, so they apparently are not an influence. I found that by commenting out the is_plugin_active_for_network existence check that I could then upload the allowed image types. No idea why that’s an issue though.
Could you simply check if a function in the plugin is defined or not?
Solved.
The problem apparently, is that the return $mimes was in the wrong place.
It needs to be at the very bottom of the function, outside the conditional statements.
Otherwise, when testing either as a Super Admin or in any situation where the conditional statements return false, no $mimes are handed back by the plugin.
Here is the working code.
function restrict_mime($mimes) {
if ( function_exists('is_plugin_active_for_network') ){
if ( is_plugin_active_for_network( 'wp-ultimo/wp-ultimo.php' ) ) {
if ( !is_super_admin() ) {
//get user id
$user_id = get_current_user_id();
//define the Premium Pro plan ID
$plan_id = 52;
// restrict MIME types if the current user doesnt have Premium Pro plan
if ( !wu_has_plan( $user_id, $plan_id ) ) {
$mimes = array(
'jpg|jpeg' => 'image/jpeg',
'gif' => 'image/gif',
'png' => 'image/png',
'pdf' => 'application/pdf',
'txt' => 'text/plain',
'csv' => 'text/csv',
'doc' => 'application/msword',
'docx' => 'application/vnd.openxmlformats-officedocument.wordprocessingml.document',
'ppt' => 'application/vnd.ms-powerpoint',
'pptx' => 'application/vnd.openxmlformats-officedocument.presentationml.presentation',
'xls' => 'application/vnd.ms-excel',
'xlsx' => 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'
);
}
}
}
}
return $mimes;
}
add_filter('upload_mimes','restrict_mime');
Hah! Of course. I can’t tell you how many times I’ve made the same mistake. Probably why I failed to see such a blunder even though the symptom was staring me in the face. I’m glad you solved it.
