The checkbox field creates a list of tick-able options. This field is useful to add categories or other information to your post or page.

Creating a checkbox field

The checkbox field contains options to customize your field:

  • Choices: You can populate the tick-able list with choices. Each choice is entered on a new line. Each choice requires a value and a label which are broken by a ‘:’. If no ‘:’ is found, the field will use the Label as the Value.

Template usage

The API returns different data to these functions:

  • get_field: an array of values
  • the_field: a string containing all values separated by a comma
<?php

*  Displaying single value
*/
 
?>
<p>Color: <?php the_field('field_name'); ?></p>

*/

$value = get_field('field_name');
$label = $field['choices'][ $value ];
 
?>
<p>Color: <?php echo $label; ?></p>
<?php
 
/*
*  Displaying multiple values
*/

<p>Colors: <?php echo implode(', ', get_field('field_name')); ?></p>
