Cannot loop checkbox values

  • Hello everyone

    I am using ACF Pro and embedded a code referencing the page below to loop the values assigned to a checkbox field:

    The code embedded is shown as follows:

    <?php $toilets = get_field(‘toilets’);
    if($toilets): ?>
    <?php foreach($toilets as $toilet): ?>
    <?php echo $toilet[value]; ?>
    <?php endforeach; ?>
    <?php endif; ?>

    The error returned is:

    Warning: Invalid argument supplied for foreach() in…

    Also, what echo returns for the value of get_field(‘toilets’) is:

    s:41:”s:33:”a:1:{i:0;s:15:”indoor toilet”;}”;”;

    Does this mean the checkbox field does NOT produce an array?
    Could someone tell me how you can display entered values of a checkbox field only?

    Thank you in advance,


  • You can define the output value of the checkboxes. Did you choose “output as array”?

    Also important: Are you using the get_field() within a WordPress loop? If not, you have to enter a post id. (get_field)
