Notifications still not working + missing images

Okay, now when I use the handle function, I get warnings.

function handle_form_submission( $form, $fields, $args ) {
    
    print_r($fields);
    
    $email = af_get_field( 'email' );
	$empfaenger = '[email protected]';
	$betreff = 'Der Betreff';
	$nachricht = 'Hallo';
	$header = 'From: [email protected]' . "\r\n" .
	    'Reply-To: [email protected]' . "\r\n" .
	    'X-Mailer: PHP/' . phpversion();
	
	mail($empfaenger, $betreff, $nachricht, $header);
    
}
add_action( 'af/form/submission', 'handle_form_submission' );

Warning: Missing argument 2 for handle_form_submission(), called in /www/htdocs/w00cbd80/akteure-der-region/wp-includes/class-wp-hook.php on line 288 and defined in /www/htdocs/w00cbd80/akteure-der-region/wp-content/themes/akteuretheme/functions.php on line 15

Warning: Missing argument 3 for handle_form_submission(), called in /www/htdocs/w00cbd80/akteure-der-region/wp-includes/class-wp-hook.php on line 288 and defined in /www/htdocs/w00cbd80/akteure-der-region/wp-content/themes/akteuretheme/functions.php on line 15

I receive the same warnings although the code inside the function executes well.

Hi!

Regarding the warnings you are getting I think it’s because you need to specify the amount of arguments your hook takes. Something like: add_action( 'af/form/submission', 'handle_form_submission', 10, 3 );. I realize now that this is missing from the documentation, will add it soon!

I just tried setting up a form with some image fields, both individual and in repeaters, but I unfortunately didn’t run into the same issues as you. My images were properly uploaded and included in the email. Could you check your uploads directory and see if your images are uploaded on form submission? Thank you!
