[Plugin: Gravity Forms] Dynamically populating form field isn't working (2 posts)

    Hey.
    I'm having some problems with my Gravity Forms form. It's a multi page form, and I need to populate a field on page 2 using post values from page 1. But it's not working. Of course the field on page 2 is configured to "Allow field to be populated dynamically" and the field's parameter is set to "name". Here's my code:

    add_filter('gform_field_value_name', 'name_population_function');
    function name_population_function($value){
    $name = $_POST['input_2'] . ' ' . ( ! empty( $_POST['input_3'] ) ? ( $_POST['input_3'] . ' ' ) : NULL ) . $_POST['input_1'];
    return $name;
    }

    When I print the value of $name variable using var_dump($name); it's actually correct.

    If I change the $name to $name = 'Last Middle First'; it's populating the field as it should.

    Thank you for your help.

    For test purposes I changed my code to:

    add_filter('gform_field_value_name', 'name_population_function');
    function name_population_function($value){
    $name = 'Test';
    if ( ! empty( $_POST['input_1'] ) && ! empty( $_POST['input_2'] ) ) {
    $name = $_POST['input_2'] . ' ' . ( ! empty( $_POST['input_3'] ) ? ( $_POST['input_3'] . ' ' ) : NULL ) . $_POST['input_1'];
    //var_dump( $name );
    }
    return $name;
    }

    If I uncomment the line with var_dump the value of variable $name is again set correctly, but the field on page 2 is prepopulated with value Test. Probably this filter is also called on page 1 so is it possible that the plugin caches this value? I don't use a caching plugin, so don't know why it's not working.
