Disable for specific CF7

The ability to skip hCaptcha verification on the specific form was added for CF7 in v2.9.0, which will be published in days.

Here is the instruction on how to do it.

Here is the working example how to skip hCaptcha verification for CF7 form with id = 177.

/**
 * Filters the protection status of a form.
 *
 * @param string     $value   The protection status of a form.
 * @param string[]   $source  The source of the form (plugin, theme, WordPress Core).
 * @param int|string $form_id Form id.
 *
 * @return bool
 */
function hcap_protect_form_filter( $value, $source, $form_id ) {
	if ( ! in_array( 'contact-form-7/wp-contact-form-7.php', $source, true ) ) {
		// The form is not sourced by CF7 plugin.
		return $value;
	}

	if ( 177 !== (int) $form_id ) {
		// The form has id !== 177.
		return $value;
	}

	// Turn off protection for form with id = 177.
	return false;
}

add_filter( 'hcap_protect_form', 'hcap_protect_form_filter', 10, 3 );

As I mentioned above, it is still not released. v2.9.0 will be released in several days.

Today, you can get and build v2.9.0 from GitHub only, using appropriate branch.
