我想在WordPress上的特定页面上添加自定义短代码

Question

I need to add custom shortcode only on the specific page through the header.php

This is confusing me a bit since I've tried to put is_page() only in if() but it doesn't work. I need from my code to do the following:

Example code is here:

$page = 'page_slug';
if (is_page($page)) {
   do_shortcode('[shortcode]');
}

From some reason, this doesn't work.

Answer 1

You execute the function get_page in the if statement. Even though it is evaluated to false, the function is executed, I bet the problem comes from that.

Consider changing get_page to have it only returning boolean but not doing anyhting else.

Of course, then you can leave only the if statement and get rid of the else.

EDIT: Here's an example. else statement is empty, there shouldn't be anything but "bar" is printed as the function is executed to determine if if statement should be entered or not.
