A simpler version of the problem with clean wordpress install and twentyfourteen theme:
What I did:
– Created an about page
– Assigned the about page to the full width template.
– Created a new ACF field group assigned to the about page.
-Added a new flexible content field with slug multicontent.
– Added a new layout called gallery.
-Added a Gallery field inside this layout called images.
– Then added another layout called single_image
– and finally added inside this layout an image field called image.
THE CODE:
<?php
// check if the flexible content field has rows of data
if( have_rows('multicontent') ): // success
// loop through the rows of data
while ( have_rows('multicontent') ) : the_row(); // success
// check current row layout
if( get_row_layout() == 'gallery' ): // success
// check if the nested repeater field has rows of data
if( have_rows('images') ): // success
echo '<ul>';
// loop through the rows of data
while ( have_rows('images') ) : the_row(); // success
$image = get_sub_field('image'); // Problem! retrieves nothing
echo '<li><img src="' . $image['url'] . '" alt="' . $image['alt'] . '" /></li>'; // displays the list but with no links even if i remove the ['url'] array parts
endwhile;
echo '</ul>';
endif;
elseif( get_row_layout() == 'single_image' ): // success
$one_image = get_sub_field('image'); // success
echo '<img src="' . $one_image['url'] . '" />'; // success
endif;
endwhile;
else :
// no layouts found
endif;
?>
THE OUTPUT:
<ul>
<li><img alt="" src=""></li>
<li><img alt="" src=""></li>
<li><img alt="" src=""></li>
</ul>
<img src="http://localhost/wpsimple/wp-content/uploads/2014/11/foliothumb2.jpg">
I wonder if anyone can replicate this problem or is it just me.
If there is an obvious mistake in the code above I would appreciate your feedback.
Actually the above code needs $image = get_sub_field(‘image’); in order to populate the list but the fields remain empty no matter what i tried.
I suppose there is no ‘image’ field inside the gallery but how is it called?
