Hi,
I’m trying to get the output values from a checkbox field added to WordPress’s built in post_class short code. I may be over thinking this but can someone let me know if this is possible. Listed below are my references. Thank you.

<?php
$classes = array(
'class1',
'class2',
'class3'
);
?>
<?php post_class( $classes ); ?>>
<?php echo implode(' ', get_field('field_name')); ?>
seems a little hurdled around..
<?php
$checkboxValues = get_field('field_name'); //Change field_name to your checkbox field
$extraClasses = (is_array($checkboxValues) ? implode(' ', $checkboxValues) : $checkboxValues); //If its an array, implode it! otherwise just use the value
?>
<?php post_class( $extraClasses ); //This goes in your <article> element (or whatever you use) ?>
On a second look it seems you can pass an array to post_class aswell.. so you really only need one line of code:
<?php post_class(get_field('field_name')); ?>
Thanks Jonathan. Works perfectly.
Just wondering. Is it possible to include multiple fields in this line of code?
It’s possible but not as is..
you’ll need to use array_merge on the fields first then put the new variable in the post_class function
I’m sort of a front-end guy. Could you start me off lol?
Ahh I used to be one too, then I became both after a while 😉 It’s inevitable in a small business
Anyway, this should do it provided that both fields are arrays!
<?php
$checkboxValues = get_field('field_name'); //Change field_name to your checkbox field
$morecheckboxValues = get_field('field_name_2'); //Change field_name to your checkbox field
$extraClasses = array_merge($checkboxValues, $morecheckboxValues);
?>
<?php post_class( $extraClasses ); //This goes in your <article> element (or whatever you use) ?>
Thanks man. I really appreciate the time you took to help me. Best wishes.
