ACF Fields

Display a field
<p><?php the_field('field_name'); ?></p>

Retrieving a field as a variable
<?php
$variable = get_field('field_name');
// do something with $variable
?>

Using conditional statements
<?php
if(get_field('field_name'))
{
	echo '<p>' . get_field('field_name') . '</p>';
}
?>

Working with Array values
<?php
$values = get_field('field_name');
if($values)
{
	echo '<ul>';
	foreach($values as $value)
	{
		echo '<li>' . $value . '</li>';
	}
	echo '</ul>';
}
// always good to see exactly what you are working with
var_dump($values);
?>

Working with Images – URL
<img src="<?php the_field('image_test'); ?>" alt="" />

Working with Images – ID
<?php $image = wp_get_attachment_image_src(get_field('image_test'), 'full'); ?>
<img src="<?php echo $image[0]; ?>" alt="<?php echo get_the_title(get_field('image_test')) ?>" />

Working with the Repeater Field
<?php if( have_rows('repeater_field_name') ): ?>
    <ul>
    <?php while( have_rows('repeater_field_name') ): the_row(); ?>
        <li>sub_field_1 = <?php the_sub_field('sub_field_1'); ?>, sub_field_2 = <?php the_sub_field('sub_field_2'); ?>, etc</li>
        <?php
        $sub_field_3 = get_sub_field('sub_field_3');
        // do something with $sub_field_3
        ?>
    <?php endwhile; ?>
    </ul>
<?php endif; ?>

Randomly select a repeater field row
<?php
$rows = get_field('repeater_field_name');
$row_count = count($rows);
$i = rand(0, $row_count - 1);
echo $rows[ $i ]['sub_field_name'];
?>

Getting values from another page
<?php
$other_page = 12;
?>
<p><?php the_field('field_name', $other_page); ?></p>
<?php
// get variable
$variable = get_field('field_name', $other_page);
// repeater field: note that the_sub_field and get_sub_field don't need a post id parameter
if( have_rows('repeater_field_name', $other_page) ): ?>
    <ul>
    <?php while( have_rows('repeater_field_name', $other_page) ): the_row(); ?>
        <li>sub_field_1 = <?php the_sub_field('sub_field_1'); ?>, sub_field_2 = <?php the_sub_field('sub_field_2'); ?>, etc</li>
        <?php
        $sub_field_3 = get_sub_field('sub_field_3');
        // do something with $sub_field_3
        ?>
    <?php endwhile; ?>
    </ul>
<?php endif; ?>

Query posts with ACF values
<?php
$posts = get_posts(array(
	'numberposts' => -1,
	'post_type' => 'event',
	'meta_key' => 'location',
	'meta_value' => 'melbourne'
));
if($posts)
{
	echo '<ul>';
	foreach($posts as $post)
	{
		echo '<li><a href="' . get_permalink($post->ID) . '">' . get_the_title($post->ID) . '</a></li>';
