I search for the WordPress Functions which absorb the $_POST Globals. I searched for it but found nothing...
I want to write a script which works with Post Globals but they are "blocked" by the WP Search Function. That's the reason I look for this functions...
No, $_POST doesn't get unset. You can access it from any plugin you write. Nothing special needs to be done.
No, that isn't the problem. Look, I wrote a plugin which works with a form but the Problem is that when I send the form wordpress calls the search result template. And I search for the functions which call this template so that I can block this call of the search function if one special Post field is specified.
Oh. In that case, don't use parameter names that WordPress is already using, like "s".
