  • What I had was an ACF form on a frontend page where the user could create new posts. Something like this:

    acf_form( array(
    	'form'			=> true,
    	'id'			=> 'prefix-acf-form',
    	'post_id'		=> 'new_post',
    	'new_post'		=> array(
    		'post_type'		=> 'post_type_here',
    		'post_status'	=> 'publish',
    	'field_groups'	=> array( Class_Here::get_acf_key( 'edit' ) ),
    	'honeypot'		=> false,
    ) );

    The idea being that I would save post_content field as the actual post content for the post.

    The problem was that I was using global $post, so the pages content was being displayed instead of the expected nothing.

    The solution was to check if the passed $post_id is either empty or new_post and if it is, return the value early before attempting to get the post content.

     * Return post content if possible
     * @param String $value - Field content
     * @param Mixed $post_id - Post ID, Empty, or 'new_post'
     * @return String - Post content for given post ID
    function themeprefix_acf_post_content( $value, $post_id ) {
    	// We already have a value for some reason, return it.
    	if( ! empty( $value ) ) {
    		return $value;
    	// We do not have a $post_id to pull from, return early.
    	if( empty( $post_id ) || 'new_post' == $post_id ) {
    		return $value;
    	return get_post_field( 'post_content', $post_id, 'edit' );
    add_filter( 'acf/load_value/name=post_content', 'themeprefix_acf_post_content', 10, 2 );
