Yoast SEO | How to create custom variables

Question

Was just wondering if there is a way to create a custom variable so that I can add my custom variable created in the Meta title of the page.

Yoast SEO has a list of variables predefined here.

It would be great if I could create a variable of my own. Is there any way to get this?

Thanks in advance!

You have two options for this.

1. Add filter for change exist variable.
2. Add your new custom variable.

If you want to change exist variable, you can do it like this:

// define the wpseo_replacements callback
function filter_wpseo_replacements( $replacements ) {
    if( isset( $replacements['%%page%%'] ) ){
        $replacements['%%page%%'] = 'Page x of y';
    }
    return $replacements;
};
// Add filter
add_filter( 'wpseo_replacements', 'filter_wpseo_replacements', 10, 1 );

And if do you want to add custom variable you can do it like this:

// define the custom replacement callback
function get_myname() {
    return 'My name is Moses';
}

// define the action for register yoast_variable replacments
function register_custom_yoast_variables() {
    wpseo_register_var_replacement( '%%myname%%', 'get_myname', 'advanced', 'some help text' );
}

// Add action
add_action('wpseo_register_extra_replacements', 'register_custom_yoast_variables');

I hope I was helpful to you.
