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 james
    thanks, but still can’t get it to work. do you think the 2 , ‘option’s are helping?? i’ve tried without – no joy

  • 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
