Hello,
I have a repeater field and would like to use an object field to read out a repeater field from another field group.
I use the following code:
<?php if ( have_rows( 'repeater_field' ) ) : ?>
<?php while ( have_rows( 'repeater_field' ) ) : the_row(); ?>
<?php $post_objects = get_sub_field( 'object_field' ); ?>
<?php if ( $post_objects ): ?>
<?php foreach ( $post_objects as $post ): ?>
<?php setup_postdata( $post ); ?>
<!-- This displays the contents of the repeater field from the other field group. -->
<?php $post_object = get_field( 'object_field' ); ?>
<?php if ( $post_object ): ?>
<?php $post = $post_object; ?>
<?php setup_postdata( $post ); ?>
<?php if ( have_rows( 'repeater_field' ) ) : ?>
<?php while ( have_rows( 'repeater_field' ) ) : the_row(); ?>
<?php the_sub_field( 'sub_field' ); ?>
<?php endwhile; ?>
<?php endif; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
<?php endforeach; ?>
<?php wp_reset_postdata(); ?>
<?php endif; ?>
<?php endwhile; ?>
<?php endif; ?>
The output is correct for the first element. The second, however, outputs the content of the first.
What do I have to adapt to my code so that the correct content is output in each case?
Hello John,
Thank you so much for your feedback.
I understand the problem with the nested loops. But I don’t understand your examples behind the links.
Maybe you can help me with a small example related to my code?
Many thanks
You need to remove the nested setup_postdata() and wp_reset_postdata() and use some other method of referencing these nested posts. This includes using some other variable name for the post object besides $post.
Here is your code with some modification
<?php
if ( have_rows( 'repeater_field' ) ) :
while ( have_rows( 'repeater_field' ) ) : the_row();
$post_objects = get_sub_field( 'object_field' );
if ( $post_objects ):
foreach ( $post_objects as $post ):
setup_postdata( $post );
$post_object = get_field( 'object_field' );
if ( $post_object ):
if ( have_rows( 'repeater_field', $post_object->ID ) ) :
while ( have_rows( 'repeater_field', $post_object->ID ) ) : the_row();
the_sub_field( 'sub_field' );
endwhile;
endif;
endif;
endforeach;
wp_reset_postdata();
endif;
endwhile;
endif;
?>
Hello John,
thanks for the code. I have implemented it and replaced the corresponding fields (repeater_field, object_field & sub_field) with my data.
But now no more output is generated.
Have I forgotten anything else?
