Template usage

The checkbox field returns an array of selected choices.

Display value

This example demonstrates how to display the selected values in a comma-delimited list.

<p>Colors: <?php the_field('colors'); ?></p>

Display values in a list

This example demonstrates how to display the selected values in an unordered list.

<?php
$colors = get_field('colors');
if( $colors ): ?>
<ul>
    <?php foreach( $colors as $color ): ?>
        <li><?php echo $color; ?></li>
    <?php endforeach; ?>
</ul>
<?php endif; ?>

Display labels in a list

This example demonstrates how to display the selected labels in an unordered list when Return Format is set to Value.

<?php

// Load field settings and values.
$field = get_field_object('colors');
$colors = $field['value'];

// Display labels.
if( $colors ): ?>
<ul>
    <?php foreach( $colors as $color ): ?>
        <li><?php echo $field['choices'][ $color ]; ?></li>
    <?php endforeach; ?>
</ul>
<?php endif; ?>

This example demonstrates how to display the selected labels in an unordered list when Return Format is set to Both.

<?php
$colors = get_field('colors');
if( $colors ): ?>
<ul>
    <?php foreach( $colors as $color ): ?>
        <li><span class="color-<?php echo $color['value']; ?>"><?php echo $color['label']; ?></span></li>
    <?php endforeach; ?>
</ul>
<?php endif; ?>

Conditional logic

This example demonstrates how to check if the choice “red” was selected in the field’s value.

$colors = get_field('colors');
if( $colors && in_array('red', $colors) ) {
    // Do something.
}

Query posts

This example demonstrates how to query posts that contain a checkbox field named “colors” with the value “red” selected. Because the checkbox field saves its value as a serialized array, it is important to use the meta_query “LIKE” comparison.

$posts = get_posts(array(
    'meta_query' => array(
        array(
            'key'     => 'colors',
            'value'   => '"red"',
            'compare' => 'LIKE'
        )
    )
));

if( $posts ) {
    // Do something.
}

Notes

Save custom

If using the local JSON feature, any custom values saved to the field’s choices will not appear on page reload. This is because the JSON file will not be updated and will override any field settings found in the database.
