Hook Syntax Help

  1. Hello,

    Could you please help me with the correct syntax for using the hook.

    1	add_filter('gform_field_value_your_parameter', 'my_custom_population_function');
    2	function my_custom_population_function($value){
    3	    return 'boom!';
    4	}

    My form ID is 15, field_ID 11 and parameter name: page_name

    I would like to always return the current post title in the page_name parameter

    I have already setup this up to populate dynamically.

    many thanks,
    Andy

    add_filter('gform_field_value_page_name', 'page_name_filler');
    	function page_name_filler($value){
                //this is where you'd put your PHP code for grabbing the current post title.
    	    return 'boom!'; //return the variable or value to the field.
    	}

  4. i have used:

    add_filter('gform_field_value_page_name', 'page_name_filler');
    	function page_name_filler($value){
                //this is where you'd put your PHP code for grabbing the current post title.
    	    echo get_the_title(); //return the variable or value to the field.
    	}

  5. You should be using return rather than echo on line 4, otherwise your function won't return anything.
