When a user asks a question on my forum, I wanted to be able to add user email addresses to be notified by email of the new question. I have multiple categories and for each category there is at least one forum leader. I would like each of them to get a notification email when a new question is posted to their category. Which hook would allow me to add user emails to the new question notification email that goes to the admin?
I want to perform additional queries to the database Mysql. Error output. In older versions this worked. What am I to do?

WordPress 5.0.3
Hi,
I’d like a file upload that can take multiple files. I updated upload_args[“multiple”] to true, but if I cannot drag two files onto the uploader, nor can I select two files if I click “choose file.” If I first select one file and then another, then the first file gets replaced by the second.
Here is the code I’m using:
add_filter( 'ap_question_form_fields', function( $form ) {
// Upload field.
$form['fields']['screenshot'] = array(
'label' => __( 'Screenshot' ),
'desc' => __( 'Upload screenshots of your website.' ),
'type' => 'upload',
'upload_args' => array(
'multiple' => true, // Allow single image upload.
),
);
return $form;
} );
In spite of the code above, I see that the front end only show 1 file allowed for upload:

Thanks for any help,
Peter.
Hello? How can i translate pages in to russian and ukrainian languages?
Hi there. Very cool plugin. I have a use case where using a listing/directory theme that uses WP Job Manager. We’d like to allow registered members to ask questions of listing owners and allow listing owners to answer them on the directory listing detail page. Basically, filter the Q&A to the post. Given users can post new listings we’d need this to be automagic.
Is something like this possible with this plugin?
Thanks in advance!
Steven
