Your array definitions aren’t correct. This… elseif($_REQUEST[“price”] == 20){$price = “array( ’19’, ’20’ )”;} … creates a literal string that reads “array( ’19’, ’20’ )”. Remove the quotes. elseif($_REQUEST[“price”] == 20){$price = array( ’19’, ’20’ );} That should give you PHP arrays.

It’s not entierly clear to me what you are trying to achieve, but let’s say you were trying to get … Read more

In the default usage this is impossible due to the nature of the default comment walker which always directly outputs. But the function allows to provide a custom walker.

You need a filter not an action. Something like this (notes are commented into the code. You have a few PHP errors that you need to correct): function signup_validate_insert($post){ $errors = false; if (isset($post[‘submit_msg’])) { // validate , insert into database } return $errors; } add_filter(‘signup_insert’, ‘signup_validate_insert’); $errors = apply_filters(‘signup_insert’, $_POST); if((!empty($errors))){ // $errors is … Read more
