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);
?>
<h1><?php echo $subTitle; ?></h1>
<?php
if ($skills) : ?>
<ul>
<?php foreach ($field['choices'] as $v => $l) : ?>
<li><?php echo $l; ?></li>
<?php endforeach; ?>
</ul>
<?php endif;
?>
<?php endif;
?>
$skills = the checkboxes
print_r($skills);

Thank you. Can you tell me why it’s necessary to use _ instead of – here or point me in the right direction to learn more?
I’m using Contact 7 forms in this way. I have a flexible content field I’m using as a page builder.
I added my shortcode to a text field schedule_a_demo_form like this;
[contact-form-7 id="xxx" title="Schedule A Demo"]
In my template I do this;
$scheduleADemoForm = get_sub_field('schedule_a_demo_form');
echo do_shortcode($scheduleADemoForm);
Also, to prevent users from altering the shortcode in the text field I added a class admin-readonly to the wrapper and in my admin-styles.css added this style;
.admin-readonly {
pointer-events: none;
}
This prevents them from accessing the input (unless they know how to use developer tools that is 🙂 )
Got it! This just happens to be a nested flexible content field.
<?php if (get_row_layout() == 'flexibl_content_field') :
$layouts = get_sub_field('sub_flexible_content_field');
$layoutsCount = count($layouts);
?>
and use it like this in the while loop
<div class="col-md-6 <?php echo $layoutsCount == 3 ? 'col-lg-4' : 'col-lg-6'; ?>
Thanks for the thorough examples @hube2! The get sections as an array code works perfectly for my needs.
