WordPress变量在自己的php文件中不起作用

Question

I wrote my own PHP file and include it to Wordpress using: http://www.paulund.co.uk/rewrite-urls-wordpress

But now if i try in this file use Wordpress variable or function (for example get_header();) i see only blank screen. I understand that this file can not use these variables but how can i link this file with Wordpress?

I think it is simple and i tried to find answer but i don't know how to name that. Can you please help me?

I see this error reason: Fatal error: Call to undefined function get_header() in /home1/colleie6/public_html/wp-content/themes/flatads/filter.php on line 9

Answer 1

Try including wp-load.php, as outlined on this answer (as per the comments, you don't need the other files).

EDIT

As per the comment from Steve Buzonas, this answer's wrong for your particular situation. I missed the mention of the tutorial, and thought you had a standalone page (much like the other question I linked to). Sadly, since it's the accepted answer, I can't delete it.

Looking at the tutorial, it looks like the code should be added to your theme's functions.php (though I'm tempting fate by not testing it).
