[英]Include php file in Wordpress' functions.php not working for header.php
I have included the line below in my functions.php
file (at the top, also tried that line at the bottom of the code). 我已经在我的
functions.php
文件中包含了以下行(在顶部,在代码底部也尝试了该行)。 I can access variables and all other stuff defined in that file in all templates . 我可以在所有模板中访问该文件中定义的变量和所有其他内容。 But when I try to
echo $something
from that file within the header.php , nothing shows up. 但是,当我尝试从header.php中的该文件中
echo $something
,什么都没有显示。 No content, no error message. 没有内容,没有错误消息。
require_once '/path/to/file.php';
Ok, after lots of trying I just found out that using the line from above inside the functions.php with 好的,经过大量的尝试,我发现在functions.php中使用上面的代码
global $something;
echo $somtehing;
in the header.php shows the value inside the wordpress header. header.php中的内容显示了wordpress标头中的值。
global $something
is not needed in template files though. 模板文件中不需要
global $something
。 Can please anyone explain me why? 能否请任何人解释我为什么?

Thanks! 谢谢!
I think you can create a shortcode and echo shortcode to header.php https://codex.wordpress.org/Shortcode_API 我认为您可以创建一个简码并向header.php回显简码https://codex.wordpress.org/Shortcode_API
example 例
function foobar_func( $atts ){
return "foo and bar";
}
add_shortcode( 'foobar', 'foobar_func' );
and call in header 并调用标题
<?php echo do_shortcode('[foobar]'); ?>
