This article mainly introduces the method of using wp_head() function in WordPress. It has certain reference value. Now I share it with you. Friends in need can refer to

wp_head() Function:

Use this function in WordPress themes to control the tag content between <head>…</head>.

To output the head tag part in html through the header.php template file,

wp_head is added to the head tag of most themes () function,

WordPress, themes or plug-ins can add content to the head tag of the website by giving the wp_head function.

Usage:

Please make sure all your pages use <?php wp_head(); ?>

The header.php template of many themes supports the wp_head() function by default. If it is not supported, you can add it yourself. The adding method is as follows:

Add <?php wp_head(); ?> between <head>…

</head>

You can dynamically add code to <head></head> when making a plug-in, such as advertising code, etc.

function my_wp_head() {
	echo "<link rel=&#39;stylesheet&#39; href=&#39;../Avada-Child-Theme/css/test.css&#39; type=&#39;text/css&#39; />";
	echo &#39;<meta name="关键字" content="测试内容" />&#39;;	
}
add_action(&#39;wp_head&#39;, &#39;my_wp_head&#39;);

Copy after login

Open any front-end page, right-click "View Source Code" and search for the entered content. If it appears, it means success.

Generally, after the modification is successful, you have to wait for a while to refresh. If you enable cache/use cache plug-ins, you need to clear the cache.

Correspondingly, we will have wp_footer() and wp_sidebar() functions. The usage method is the same as above.
