Override
To override this PHP function, use this hook in your child theme or plugin ("my_custom" can be changed):
PHP
add_filter('pre_post_meta', 'my_custom_post_meta', 10, 3); //The last integer must be 1 more than the actual parameters
function my_custom_post_meta($null, $meta, $options){ //$null is required, but can be ignored
//Write your own code here
return true; //Return true to prevent the original function from running afterwords
}
You can completely disable this PHP function with a single line actions:
PHP
add_filter('pre_post_meta', '__return_false');
