the_post action not working

  • Hello! I’m pretty new to the inner workings of wordpress and I’m having a problem trying to get a function to display in my custom post type.

    Ideally, I’d like to have a bit of html automatically added to the front end of my custom post type every time I publish a new one.

    from what I understand, putting this in my child theme’s functions.php should have done it:

    add_action( 'the_post', 'teaching_part_one' );
function teaching_part_one(){
    ?>
    <p>custom code</p>
    <?php
}

    but when I put that in and update it, it will display

    “custom code custom code
    custom code custom code
    custom code custom code”
    etc…

    in the header of every page on my site, which confuses me, because I thought that would hook into (not sure if i’m using that correctly) the posts on my site.

    Would anybody know what I might be doing wrong, and how I might be able to add code that will display in all of my posts automatically, preferably to the child theme?

    thanks for reading my post, and thank you in advance for the help!

    The the_post hook is for modifying the post object. Not a hook at occurs when the post is rendered. It actually occurs inside setup_postdata(), not the_post(); which for the main query occurs before the any of the template is rendered. This is why it’s rendering your code at the top of the page.

    If you want to add code to the template for the post, you would need to either:
    1. Edit the template itself.
    2. Filter the_tite or the_content, based on what you want to change.
    3. Hook onto an action provided by the theme/plugin.

    oh ok, thank you so much! I filtered the_content for single posts and it seems to work just how I wanted.

    add_filter( 'the_content', 'teaching_part_one' );
function teaching_part_one($content){
	if( is_singular('teachings') ) {
		$content .= '<p>custom code</p>';
    	}
    	return $content;
}

    thank you again!
