How to call WordPress PHP file using external js file

Question

I have added custom PHP file in WordPress directory and added following line to use WordPress functions:

require ('../wp-blog-header.php');

Now I am able to use WordPress functions but unable call this file from javascript in ajax.

When I removed following line then I am able to call this file:

require ('../wp-blog-header.php');

Please suggest how can I solve this issue.

Answer 1

looks like this is standard behavior of WP

change

require ('../wp-blog-header.php');

to this line

require(dirname(__FILE__) . '../../wp-config.php'); //path to Your wp-config.php file

$wp->init();
$wp->parse_request();
$wp->query_posts();
$wp->register_globals();
//$wp->send_headers();
