Trying the above code is causing a warning error to be thrown with my usage and I don’t understand why.
Warning: Invalid argument supplied for foreach()
<?php
$portfolioContent = get_field('portfolio_content'); // this is the group field
if ($portfolioContent) :
$skills = $portfolioContent['skills'];
$field = get_field_object($skills);

$skills = the checkboxes
print_r($skills);
