Loop Repeater Based on Sub Field Values

I have a Repeater Field called: package_name
In it i have a Select Sub Field called:package_group
In Select Sub Field i have the option:caci_facials : Caci Facials.

I am trying to get all package_name with Select Sub Field “Caci Facials” (or is it ‘Caci Facials’ or caci_facial’ or ‘caci facials’) to be listed on a different page.

Normally when i have to show Advanced Custom Fields on other pages i have to add ‘option’ into $rows = get_field(‘my_field’, ‘option’); for it to work.

ALSO, its all wrapped up in a shortcode.

I have tried the code on another page in this forum, changing this:

if(have_rows('field_name')):
   while(have_rows('field_name')): the_row();
      if(get_sub_field('sub_field') == 'functional assay'):
         the_sub_field('sub_field');
      endif;
   endwhile;
endif;

to

// PackageList shortcode
function treatmentlistf($atts, $content = null) { ?>
<?php
if(have_rows('package_name', 'option')):
   while(have_rows('package_name', 'option')): the_row();
      if(get_sub_field('package_group') == 'caci_facials'): ?>
         <h2> Test hello</h2>
     <?php endif;
   endwhile;
endif;
?>

<?php }
add_shortcode('treatmentlist', 'treatmentlistf');

Nothing happens – rest of page shows but not shortcode content.
What am i doing wrong

Right, couldn’t come up with a solution to this so gave up and added them manually instead.

Hi @tomwgf

You need to return the shortcode instead of printing it like that. It should be something like this:

// PackageList shortcode
function treatmentlistf($atts, $content = null) { ?>
<?php
if(have_rows('package_name', 'option')):
   while(have_rows('package_name', 'option')): the_row();
      if(get_sub_field('package_group') == 'caci_facials'): ?>
         return '<h2> Test hello</h2>'
     <?php endif;
   endwhile;
endif;
?>

<?php }
add_shortcode('treatmentlist', 'treatmentlistf');

This page should give you more idea about it: https://codex.wordpress.org/Function_Reference/add_shortcode.

Hope this helps.

hi james
thanks for replying.

i tried your code – but it didn’t work.

i also tried changing return ‘<h2> Test hello</h2>’ to <?php return ‘<h2> Test hello</h2>’; ?>

is ‘option’ right, is == ‘caci_facials’ right??

Hi @tomwgf

Sorry about that. I forgot to remove the php tag. It should be working with this one:

// PackageList shortcode
function treatmentlistf($atts, $content = null) {
    $returned = "";
    if(have_rows('package_name', 'option')):
       while(have_rows('package_name', 'option')): the_row();
          if(get_sub_field('package_group') == 'caci_facials'):
             $returned .= "<h2>Test Hello</h2>";
          endif;
       endwhile;
    endif;
    return $returned;
}
add_shortcode('treatmentlist', 'treatmentlistf');

I hope this helps.

Hi @tomwgf

That’s weird. Could you please try to remove the $content = null so it looks like this?

// PackageList shortcode
function treatmentlistf($atts) {
    $returned = "";
    if(have_rows('package_name', 'option')):
       while(have_rows('package_name', 'option')): the_row();
          if(get_sub_field('package_group') == 'caci_facials'):
             $returned .= "<h2>Test Hello</h2>";
          endif;
       endwhile;
    endif;
    return $returned;
}
add_shortcode('treatmentlist', 'treatmentlistf');

The “option”s are used if you put the field group on an options page. If you put it on a post/page, I believe you don’t need it. You can also try to set a value for the $returned variable so it looks like this:

$returned = "the value";

If it the shortcode only returns “the value”, it means there is something wrong with the field.

I hope this makes sense.

Saw this post and it helped me with my shortcode for a repeater field, so I thought I’d post the code I used:

// Box Navigation shortcode
function boxnavf($atts) {
   ob_start();
	echo '<div class="box-navigation" >   ';
   if( get_field('box-navigation') ):
      echo ' <ul class="boxes">';
     while( has_sub_field('box-navigation') ):
	  echo '<li class="item">';
	  echo '<a href='.get_sub_field("box-link").'>' .get_sub_field("box-page-name"). '</a>';
	  echo '</li>	';
    endwhile;
	  echo '</ul/>';
    endif;
	  echo '</div>';
	  
     $output = ob_get_clean();
	 return $output; 
  
}
add_shortcode('boxnav', 'boxnavf');

Thanks
Dan
