gform_display_add_form_button

Description

By default, the “Add Form” button and legacy shortcode UI will only be available on the Post or Page edit screens using the classic editor. The gform_display_add_form_button filter can be used to enable it for other pages or scenarios.

Note: The “Add Form” button requires a TinyMCE input, so in order to display it, you must first include a TinyMCE input to your page.

Usage

add_filter( 'gform_display_add_form_button', 'display_form_button_on_custom_page' );

Parameters

$display_add_form_button bool
Indicates if the Add Form button and shortcode UI should be included for the current admin page.

$display_add_form_button = ( ! class_exists( 'GF_Block' ) || class_exists( 'Classic_Editor' ) ) && in_array( RG_CURRENT_PAGE, array(
	'post.php',
	'page.php',
	'page-new.php',
	'post-new.php',
	'customize.php',
) );
