I'm triying to return the value for the product qty.
I need to validate qty field. It should be trivial no?

Check this out: http://projets.collectiv.ca/northsec-2013/

Something like this maybe ...

But in gform_field_validation hook.

I would like to test if my list field rows == product quantity in the second step.
Since the quantity field is in the step 1, it is not validated on step 2

The quantity would be use to populate the field list with the required rows.

I would really appreciate some help on this one.

All I need to do is to populate a list field with a qty collected in the first step.
Here is the code:

// Populate list with selected quantity
add_filter("gform_pre_render_1", "pre_populate_row_list");
function pre_populate_row_list($form){

	$field_id = 15; // Member list
	$product_qty = rgpost('input_30');
	$list = rgpost('input_15');

	$current_page = GFFormDisplay::get_current_page($form["id"]);

	//if($current_page == 2){
		foreach($form['fields'] as &$field){
			if($field['id'] != $field_id)
				continue;

			// Dynamic Population doesn't work :\
			$array = array_fill(0, $product_qty ,'');
			$field['choices'] = array_fill(0, 2, $array);
			//$field['label'] = implode(',',$field['choices']);
		}
	//}
	return $form;
}

So I don't think you can use pre_render to take something from one section of a form and populate another. Because when pre_render has run, no one has typed anything in yet.

Have you looked at this:

Thanks. Thats how I did it finaly.

add_filter("gform_field_validation_1_15", "validate_list_field", 10, 4);
function validate_list_field($result, $value, $form, $field){

    $product_qty = rgpost('input_33');

    // Test if equal quantity
    if( count($current_emails) != $product_qty ){
        $result["is_valid"] = false;
        $result["message"] .= sprintf(__('<br/>Vous devez inscrire (%d) personnes dans votre équipe.','nsec'), $product_qty);
    }

    // always return result
    return $result;
}
