Advanced Custom Fields: multiple checkbox values displaying conditional data

问题

I'm using Advanced Custom Fields with Wordpress and I’m using the checkbox field to display data depending on what is selected. The return value of the field is set to 'Value'.

I have two checkboxes and I’m getting data based on whether one or the other is selected. But is it possible to show data when both checkboxes are selected?

For example:

<?php $options = get_field('options');?>
<?php if( $options && in_array('option-1', $options) ): ?>
  <p>Option 1 selected</p>
<?php elseif ( $options && in_array('option-2', $options) ): ?>
  <p>Option 2 selected</p>
<?php elseif ( $options && in_array('option-1', $options) && in_array('option-2', $options ): ?>
  <p>Option 1 and Option 2 selected</p>
<?php endif;?>

Is this possible?

回答1:

Yes its possible using in_array_all in your last elseif for checking both checkbox selected.

     <?php $options = get_field('options');
     $options = array($options); ?>
<?php if( $options && in_array(array('option-1','option-2'), $options)): ?>
     <p>Option 1 and Option 2 selected</p>
<?php elseif ( $options && in_array(array('option-2'), $options) ): ?>
  <p>Option 2 selected</p>
<?php elseif ($options && in_array(array('option-1'), $options) ): ?> 
 <p>Option 1 selected</p>
<?php endif;?>
