Here was a simple solution that I came up with for a single checkbox. My use is to declare a title to be echoed as an <h2> or <h3> tag in the html. I post this for anyone else looking for an easy way to use a single checkbox.
if($h3 = get_sub_field('h3_option')){
echo "<h3>{$title}</h3>";
} else {
echo "<h2>{$title}</h2>";
}
I tried the “basic logic” option in on this page: https://www.advancedcustomfields.com/resources/checkbox/
<?php
$selected = get_field('field_name');
if( in_array('red', $selected) ) {
echo 'Red was selected!';
}
?>
But I found it unnecessary for my single selection.
Do note the “get_field” and “get_sub_field” difference in the 2 examples.
I am using sub_field because we are using the flex content. Big difference for those just getting to know this plugin.
