The gform_preview_form_link filter allows you to customize the admin form preview link in Gravity Forms.

  • $preview_link (string) – The form preview link HTML.

Replace the default ‘Preview’ text with custom text for the form preview link:

add_filter('gform_preview_form_link', function ($preview_link) {
    return str_replace(esc_html__('Preview', 'gravityforms'), 'Your custom link text here', $preview_link);

Place this code in the functions.php file of your active theme or a custom functions plugin.

Note: This filter was added in Gravity Forms v2.5 and is located in GFCommon::get_preview_link() in common.php.
