Calling a function in a custom php template in Wordpress

问题

I want to call a function which is in another php class that I wrote in Wordpress. However I'm confused about the syntax, e.g. to get the header on a page you just call get_header(); etc. But how do i call a function in a specific class? For example in index.php I want to call a function named this_function() which reside in say test.php. What is the syntax for this?

I suspect it to be very simple, but I can't get the syntax right, and I can't any help online.

Thanks

回答1:

First use require_once() to include the test.php, i.e.

require_once("path\test.php");

Then you can simply call this-function() and it will work.

You can use this as reference : http://www.php.net/manual/en/function.require.php
