Blocks Code
PHP
PHP output method gives you full access to WordPress functions and PHP features while rendering your block content.
Basic Usage
Access block controls through the $attributes array:
<?php if ($attributes['show_title']) : ?>
<h2><?php echo esc_html($attributes['title']); ?></h2>
<?php endif; ?>Common Examples
Working with Images
<?php
if (isset($attributes['image']['url'])) :
$image_url = esc_url($attributes['image']['url']);
$image_alt = esc_attr($attributes['image']['alt']);
?>
<img src="<?php echo $image_url; ?>"
alt="<?php echo $image_alt; ?>"
class="featured-image">
<?php endif; ?>Repeater Fields
<?php if (isset($attributes['items']) && is_array($attributes['items'])) : ?>
<ul class="items-list">
<?php foreach ($attributes['items'] as $item) : ?>
<li class="item">
<?php echo esc_html($item['title']); ?>
<p><?php echo wp_kses_post($item['description']); ?></p>
</li>
<?php endforeach; ?>
</ul>
<?php endif; ?>Using WordPress Functions
<?php
// Get related posts
$related = get_posts([
'category__in' => wp_get_post_categories(get_the_ID()),
'numberposts' => $attributes['posts_count'],
'post__not_in' => [get_the_ID()]
]);
if ($related) : ?>
<div class="related-posts">
<h3><?php esc_html_e('Related Posts', 'your-textdomain'); ?></h3>
<ul>
<?php foreach ($related as $post) : ?>
<li>
<a href="<?php echo esc_url(get_permalink($post->ID)); ?>">
<?php echo esc_html($post->post_title); ?>
</a>
</li>
<?php endforeach; ?>
</ul>
</div>
<?php endif; ?>Always use proper escaping functions:
