I’m currently trying to figure out how to get my custom url rewrites working (WP Rewrite the last two parts of the URL), while doing this I came across the following problem:
I have made a custom plugin (OOP) and I’m trying to add query variables to the public wordpress query variables list.
The code I use is the following:
/**
* Adding the trainingid var so that WP recognizes it, this is being called on the query_vars filter in the constructor.
* @param $vars the variables coming from the filter
* @return the same variables with the plugins query vars appended.
*/
function my_insert_query_vars($vars)
{
// Push the query var id in the $vars array
array_push($vars, 'trainingid');
return $vars;
}
But when I execute the following code via a shortcode on a page the array printed does not contain trainingid.
global $wp_query;
var_dump($wp_query->query_vars);
Could anybody tell me what I am doing wrong?
