Hiding empty fields

Overview

It is a common task to hide empty field values from your template. This can be achieved by using conditional statements to check the value before rending it.

The basics to conditional a statement is to use an if statement. You can read more about this core PHP function here: http://php.net/manual/en/control-structures.if.php

Examples

Example 1: Basic

This example shows how to check for a value before displaying it. Please note the use of both get_field() and the_field().

<?php if( get_field('field_name') ): ?>
	<p>My field value: <?php the_field('field_name'); ?></p>
<?php endif; ?>

Example 2: Loop

This example shows how the above methodology can be used within a loop. Please note the use of get_field_objects() to load the array.

<?php 

$fields = get_field_objects();

<?php if( $fields ): ?>
	<ul>
	<?php foreach( $fields as $field ): ?>

		<?php if( $field['value'] ): ?>
			<li><?php echo $field['label']; ?>: <?php echo $field['value']; ?></li>
		<?php endif; ?>

	<?php endforeach; ?>
	</ul>
<?php endif; ?>
