I want to check if the custom field at reply is “AllowedURL”.

If applicable to “AllowURL”, I would like to have the custom field value go into the database, but can you tell me the correct way to write the following code?

add_action( 'bbp_new_reply', 'bbp_save_reply_extra_fields', 10, 1 );
add_action( 'bbp_edit_reply', 'bbp_save_reply_extra_fields', 10, 1 );

function bbp_save_reply_extra_fields( $reply_id ) { 
	
	$input_url = $_POST['input_url'];
	
	$AllowURL = [
		'^http?://example.com/[^/]{10}$',
		'^http?://example.net/[^/]{20}$' 
	];
	
	foreach ( $AllowURL as $AU ){
		if( @preg_match( '|'.$AU.'|', $input_url ) ) {
			if ( isset($_POST) && $_POST['input_url']!='' ) {
				update_post_meta( $reply_id, 'input_url', $_POST['input_url'] );
			}
		}
	}
	
}

I look forward to your response.

so what is the code doing/not doing that you want it to ?

I presume you have $_POST[‘input_url’] set in either the reply post template or a function ?

Yes, this code does not check URLs. And I write it in “functions.php”.

can you post the code that creates the field in the reply form please
