Move the content of a custom field to the_content(); automatically

One way is using a filter. You can use the_content filter to modify the content.

add_filter('the_content','add_my_custom_field');
function add_my_custom_field($data) {
    // _FIELD_NAME_HERE_ should be replaced with the custom field name.
    $data .= esc_html( get_field('_FIELD_NAME_HERE_'));
    return $data;
}

Paste this code to your theme’s functions.php.

Thanks a lot for your help! Let’s see if it works.

Hey Animalejourbano,
I’m trying to do this with the repeater field.

I’m pulling in post_content from several page to make a tabbed section but one page is made up of a ACF repeater field.

This is what I have that’s pulling in the content

<?php

	$mypages = get_pages( array( 'child_of' => $post->ID, 'sort_column' => 'post_date', 'sort_order' => 'asc' ) );
	foreach( $mypages as $page ) {
		$content = $page->post_content;
		if ( ! $content ) // Check for empty page
			continue;
		$content = apply_filters( 'the_content', $content );
	?>
		<div class="<?php echo $page->post_name; ?>">
			<h2><?php echo $page->post_title; ?></h2>
			<?php echo $content; ?>
		</div>
<?php } ?>

and then I have this in it’s own template

<?php if( have_rows('blood_components') ): ?>
	<?php while( have_rows('blood_components') ): the_row();
		// vars
		$image = get_sub_field('image');
		$content = get_sub_field('text');
		?>

		<div class="bc">
			<img src="<?php echo $image['url']; ?>" alt="<?php echo $image['alt'] ?>" />
			<div>
				<?php echo $content; ?>
			</div>

		</div>
		<hr>
	<?php endwhile; ?>
<?php endif; ?>

I think it should be some mod to the filter but I’m not quite sure how that works.

Thanks!!
