ACF to the_content()

I have tried everything I have found in the forum in various solutions and I’m not being able to get this to work.

I am trying to have all the fields from a custom post type to get formatted with some html, and then save into the database cell for the posts content.

So for example:

ACF field names: “Bio”, “URL”, “Photo”, “Important Information”

Gets some html added to them: <a href="URL">Bio</a><img src="Photo" style="color: #444444" /> <p>Important Information</p>

Then saved into the_content.

Then, whenever our RSS, Apple News, Email Blasts, or any others that automatically query the_content, they get all of the fields they need. We use a plugin from our corporate offices that we are unable to change code in so we cant change what they are querying. The others I could add code to make them look for the fields, but because I cant change that one plug in we need to be able to make sure everything they need is in the_content. Plus, I would rather not modify plugin code in case they are updated.

This is the code I have been playing with trying to get it to work, but it isn’t.

// Functions for rendering ASF CTP's into the_content() so that they will be served up to Apple News, RSS, BMCHS Connect App, and other feeds. 

function my_acf_save_post( $post_id ){

	if(get_post_type($post_id) == 'Irish Eyes'){

		$fields = false;
	 

		if( isset($_POST['acf']) ){
			$fields = $_POST['acf'];
			$new_content = '';
			$new_content .= $fields['fieldname']['value'];			

			$my_post = array(
			'ID'           => $post_id,
			'post_content' => $new_content,
			'post_type' => 'irish-eyes'
			);

			remove_action('acf/save_post', 'my_acf_save_post', 20);
			wp_update_post( $my_post );
		add_action('acf/save_post', 'my_acf_save_post', 20);
		}
	}
}
add_action('acf/save_post', 'my_acf_save_post', 20);

I was able to get it to work by changing the calls to act/save_post to save_post. But its showing the content as Array. Not sure where to go from here now….

function my_acf_save_post( $post_id ){

		if( isset($_POST['acf']) ){
			$fields = $_POST['acf'];
			$new_content = 'before the fields';
			$new_content .= $fields;			
			$new_content .= 'after the fields';
			
			$my_post = array(
			'ID'           => $post_id,
			'post_content' => $new_content
			);

			remove_action('save_post', 'my_acf_save_post', 20);
			wp_update_post( $my_post );
			add_action('save_post', 'my_acf_save_post', 20);
		}
	
}
 
// run after ACF saves the $_POST['acf'] data
add_action('save_post', 'my_acf_save_post', 20);

Hi @justintylermoore

Keep in mind that the get_post_type() function will return the slug of your custom post type, not the name.

Also, with the priority of “20” you can use get_fields() function instead of the $_POST variable. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/acfsave_post/.

I hope this helps.

Thanks James!

What I posted in my code above is after trying just about everything. I tried placing the the slug (irish-eyes) in the get_post_type() function and it didn’t work either.

As for the $_POST[‘acf’] variable, I tried get_fields() as well. In my followup comment from above, I was able to finally get it to save to the post content, but this is what it saves:

before the fieldsArrayafter the fields

How to I get that “Array” text to save all the content of the fields from the post and not the word Array?

Hi @justintylermoore

$_POST[‘acf’] is an array, so if you join it with a string, it will show up as “Array”. You need to access the data inside the Array. An easy way to check the data is by using the var_dump() function. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/debug/.

To learn more about the Array type, please take a look at this page: http://php.net/manual/en/language.types.array.php.

I hope this helps.
