I am using gravity forms on my wordpress site and using the code from http://gravitywiz.com/better-pre-submission-confirmation/ to get the pre-submission confirmation page. I have done as instructed but there are no additional merge tags displaying in the HTML field apart from the standard ones.
I am getting the following errors on setting wp_debug mode to true.
Strict Standards: Declaration of GFCategoryWalker::start_el() should be compatible with Walker::start_el(&$output, $object, $depth = 0, $args = Array, $current_object_id = 0)
Non-static method GWPreviewConfirmation::init() should not be called statically
I don't really understand these errors and not able to find any documentation about it in relation to gravity forms.
Any help will be appreciated.
Thanks.
