See Gravity Forms Docs: gform_post_select_post_types

Examples

Add ‘event’ post type

This example allows the field to return posts of type ‘event’.

add_filter('gform_post_select_post_types', function($post_types) {
    $post_types[] = 'event';
    return $post_types;
});

Add multiple post types

This example allows the field to return posts of types ‘event’, ‘portfolio’, and ‘testimonial’.

add_filter('gform_post_select_post_types', function($post_types) {
    array_push($post_types, 'event', 'portfolio', 'testimonial');
    return $post_types;
});

Remove ‘page’ post type

This example removes the ‘page’ post type from the allowed post types.

add_filter('gform_post_select_post_types', function($post_types) {
    $post_types = array_diff($post_types, ['page']);
    return $post_types;
});

Replace default post types

This example replaces the default post types with ‘product’ and ‘service’.

add_filter('gform_post_select_post_types', function($post_types) {
    $post_types = ['product', 'service'];
    return $post_types;
});

Add post types conditionally

This example adds the ‘event’ post type only if a specific form is being rendered.

add_filter('gform_post_select_post_types', function($post_types) {
    if (rgar($_GET, 'id') == 'your_form_id') {
        $post_types[] = 'event';
    }
    return $post_types;
});

Note: Remember to replace 'your_form_id' with the actual form ID.
