Migrating from the deprecated hooks to woocommerce_get_script_data

Everything began with a comment on my tutorial about password strength meter customization in WooCommerce.

In that tutorial I used wc_password_strength_meter_params action hook, but since WooCommerce 3.3 this hook cause a PHP warning (notice).

I decided to google it, but I didn’t find any information at all 👻 After that I dived into WooCommerce source code and I found out that all of the below hooks have been deprecated since Woo 3.3:

• woocommerce_params,
• wc_checkout_params,
• wc_cart_params,
• wc_geolocation_params,
• wc_single_product_params,
• wc_address_i18n_params,
• wc_cart_fragments_params,
• wc_add_to_cart_params,
• wc_add_to_cart_variation_params,
• wc_country_select_params,
• wc_password_strength_meter_params;

Every hook from the above list has to be replaced with this one – woocommerce_get_script_data.

I will show you how! Let’s say, that we use something like this on our website.

add_filter( 'wc_checkout_params', 'misha_hook_before' );
 
function misha_hook_before( $data ) {
 
	// do stuff with the $data array and return it
 
}

So, here is what we have to do:

• Replace wc_checkout_params with woocommerce_get_script_data (line 1).
• Add one more parameter ($handle, line 3) and specify it in add_filter() function (line 1).
• Depending on the new parameter value, do specific stuff. Of course switch() is not necessary, I just used it to show you all the hooks replacements. If condition can be more than enough.

add_filter( 'woocommerce_get_script_data', 'misha_hook_after', 10, 2 );
 
function misha_hook_after( $data, $handle ) {
 
	switch( $handle ) :
		case 'woocommerce':
			// do stuff with the $data array
			break;
		case 'wc_checkout':
			// do stuff with the $data array
			break;
		case 'wc_cart':
			// do stuff
			break;
		case 'wc_geolocation':
			// do stuff
			break;
		case 'wc_single_product':
			// ...
			break;
		case 'wc_address_i18n':
			// ...
			break;
		case 'wc_cart_fragments':
			// ...
			break;
		case 'wc_add_to_cart':
			// ...
			break;
		case 'wc_add_to_cart_variation':
			// ...
			break;
		case 'wc_country_select':
			// ...
			break;
		case 'wc_password_strength_meter':
			// ...
			break;
	endswitch;
 
	return $data;
 
}

If you have more useful information about it, or a question, welcome to comments.
