Shortcode inside FAQ Schema

Hello,

Thank you for contacting the support.

You can create a custom variable and use that variable in the Schema to get the desired output. To create the variable, you can use this filter: https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-variables

Here’s an example code:

add_action( 'rank_math/vars/register_extra_replacements', function(){
        rank_math_register_var_replacement(
            'get_current_age',
            [
                'name'        => esc_html__( 'Gets the current age.', 'rank-math' ),
                'description' => esc_html__( 'Gets the current age.', 'rank-math' ),
                'variable'    => 'get_current_age',
                'example'     => 'get_current_age_callback()',
            ],
            'get_current_age_callback'
        );
    });
    function get_current_age_callback() {
        // Add the logic here
        return $age;
    }

By modifying and adding the above filter to the website, you will be able to use the variable %get_current_age% that would contain the current age of the user.

Here’s a guide that you can follow to add the code to the website:

Hope this helps.

Thank you.
