How do I redefine the wc_price variable

Hello, I understand you want to redefine the wc_price variable in Rank Math. To redefine or delete existing variables and register new ones, you can use the provided filter hooks in Rank Math.

Here is a general guide on how to redefine variables in Rank Math:

1. Redefine Existing Variables:

   • You can modify the existing variables using the rank_math/vars/replacements filter. Here is an example snippet to update the wc_price variable:

   add_filter( 'rank_math/vars/replacements', function( $vars ) {
       // Modify the existing variables here
       return $vars;
   });

2. Register New Variables:

   • To register a new variable, you can use the rank_math/vars/register_extra_replacements action hook. Here is an example snippet to register a new custom variable:

   add_action('rank_math/vars/register_extra_replacements', function () {
       rank_math_register_var_replacement(
           'custom_variable_slug',
           array(
               'name'        => esc_html__('Custom variable name.', 'rank-math'),
               'description' => esc_html__('Custom variable description.', 'rank-math'),
               'variable'    => 'custom_variable_slug',
               'example'     => 'custom_variable_callback()',
           ),
           'custom_variable_callback'
       );
   });

Please replace custom_variable_slug, Custom variable name., Custom variable description., and custom_variable_callback() with your desired values and callback function.

Hello,

Thank you for contacting support.

You cannot delete this variable because it’s added directly in the plugin source code. If you need the output to be different or perform any transformation on the prices you can register a new one with a different name using the following filter: https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-variables

All the modifications to the new variable should be done via the callback function that can be seen on the filter.

Here’s an example of using this function to get the price of a WooCommerce product dynamically and associate it with the variable %price%:

add_action( 'rank_math/vars/register_extra_replacements', function(){
    rank_math_register_var_replacement(
        'price', [
            'name'        => esc_html__( 'Price', 'rank-math' ),
            'description' => esc_html__( 'Output the price of the product', 'rank-math' ),
            'variable'    => 'price',
            'example'     => price_callback(),
        ],
        'price_callback'
    );
});

function price_callback() {
    $product = wc_get_product(get_queried_object_id());

    if( $product ) {
        $price_vat = wc_get_price_including_tax( $product );
        $price = number_format($price_vat, 2);
    }

    return $price;
}
