如何创建一个函数,将一个div放在开头<body>标签正下方的the_content中?

I have a plugin with a settings page and am wanting certain things inside the wordpress site to display when the fields are filled inside the settings page.

So for example, my global settings page has a google analytics ID field, when its entered, the google analytics tracking code will display right above the closing tag using the wp_head, and that works totally fine.

My next problem is that I am trying to do this in the_content, but the div i am wanting to appear is not in the right spot, even though you can see that i set add_action( 'the_content', 'hawp_header_schema_opening_div', 1 ); with a priority of 1.

I am very new to this I just need help with what im doing wrong.

There is no action on the_content. However, there is a filter on it. Change your code to:

 add_filter("the_content" ,  ...) ;

Or, hook your code into, lets say, wp_head action:

 add_action("wp_head" , ....) ;
