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>
