if (!empty($blocks)) {
 foreach ($blocks as $block) {
 // Access nested fields using context_data parameter
 $title = ycf_get_field('title', null, $block);
 $icon = ycf_get_image('icon', null, 'thumbnail', $block);
 $category = ycf_get_term('category', null, $block);

 echo '<h3>' . esc_html($title) . '</h3>';
 if ($icon) {
 echo '<img src="' . esc_url($icon['url']) . '">';
 }
 if ($category) {
 echo '' . esc_html($category->name) . '';
 }
 }
}
</code></pre>
<h4>Sample YAML Schema</h4>

 required: true
 options:
 maxlength: 100

 - name: category
 label: Category
 type: taxonomy
 options:
 taxonomy: category
 - name: tags
 label: Tags
 type: taxonomy
 multiple: true
 options:
 taxonomy: post_tag
 - name: content_type
 label: Content Type
 type: post_type
 - name: university
 label: University

 options:
 object_type: universities
 - name: features

 list: true
 blockKey: type
 blocks:
 - name: feature
 label: Feature Block

</code></pre>
<h4>Working with Partials</h4>
For custom partials, add the @ycf marker in the file header:
<pre><code><?php
/**
 * Custom Navigation Partial
 * @ycf
 */
</code></pre>
Then click “Refresh Template List” in the YAML Custom Fields admin page.
<h4>Template Global Fields</h4>
Template Global Fields allow you to define default values that are shared across all posts using the same template, while still allowing individual posts to override specific fields.
Setting up Template Global:
<ol>
<li>Go to YAML Custom Fields admin page</li>
<li>Enable YAML for your template (e.g., page.php)</li>
<li>Click Add Template Global to define the template global schema</li>
<li>Define fields that should have shared default values</li>
<li>Click Manage Template Global Data to set the default values</li>
</ol>
Using Template Global in Posts:
When editing a post that uses a template with Template Global fields, you’ll see a dual-field interface for each field:
<ul>
<li>Template Global (All Pages) – Read-only display showing the default value (with Edit link)</li>
<li>Page-Specific Value – Editable field for this post only</li>
<li>Checkbox – “Use template global for this field” – Toggle per field</li>
</ul>
Benefits:
<ul>
<li>Consistency: Set default values once, use across all posts</li>
<li>Flexibility: Override any field on any post individually</li>
<li>Clarity: See both global and local values side-by-side</li>
<li>Efficiency: Update template global to affect all posts at once</li>
</ul>
Data Priority (when using template functions):
When a field uses template global, <code>ycf_get_field()</code> returns data in this priority order:
<ol>
<li>Page-specific value (if “use template global” is unchecked)</li>
<li>Template global value (if “use template global” is checked)</li>
<li>Site-wide global value (if template has site-wide global enabled)</li>
<li>null (if no value exists)</li>
</ol>
<h4>Data Storage</h4>
<ul>
<li>Page/Post data: Stored in post meta with key <code>_yaml_cf_data</code></li>
<li>Template Global preferences: Stored in post meta with key <code>_yaml_cf_use_template_global_fields</code> (per-field array)</li>
<li>Template Global schemas: Stored in options table with key <code>yaml_cf_template_global_schemas</code></li>
<li>Template Global data: Stored in options table with key <code>yaml_cf_template_global_data</code></li>
<li>Site-wide global schema: Stored in options table with key <code>yaml_cf_global_schema</code></li>
<li>Site-wide global data: Stored in options table with key <code>yaml_cf_global_data</code></li>
<li>Partial data: Stored in options table with key <code>yaml_cf_partial_data</code></li>
<li>Schemas: Stored in options table with key <code>yaml_cf_schemas</code></li>
<li>Data Object Types: Stored in options table with key <code>yaml_cf_data_object_types</code></li>
<li>Data Object Entries: Stored in options table with keys <code>yaml_cf_data_object_entries_{type_slug}</code></li>
</ul>
