How to use product full description as meta description

Hi,

You can review the article here for a list of all of the available template variables that you can use — https://yoast.com/help/list-available-snippet-variables-yoast-seo/

If the variable you need isn’t available, you may have to resort to a custom variable option.

In function.php

// define the custom replacement callback
function get_fulldes() {
global $post;
return $post->post_content;
}

// define the action for register yoast_variable replacments
function register_custom_yoast_variables() {
wpseo_register_var_replacement( ‘%%fulldes%%’, ‘get_fulldes’, ‘advanced’, ‘Full Description’ );
}

// Add action
add_action(‘wpseo_register_extra_replacements’, ‘register_custom_yoast_variables’);
