  - name: hero_image
    label: Hero Image
    type: image
  - 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
    type: data_object

      object_type: universities
  - name: features
    label: Features
    type: block
    list: true
    blockKey: type
    blocks:
      - name: feature
        label: Feature Block
        fields:
          - name: title
            label: Title
            type: string
          - name: icon
            label: Icon
            type: image
          - name: description
            label: Description
            type: text
</code></pre>
<h4>Working with Partials</h4>
<p>For custom partials, add the @ycf marker in the file header:</p>
<pre><code><?php
/**
 * Custom Navigation Partial
 * @ycf
 */
</code></pre>
<p>Then click “Refresh Template List” in the YAML Custom Fields admin page.</p>
<h4>Template Global Fields</h4>
<p>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.</p>
<p><strong>Setting up Template Global:</strong></p>
<ol>
<li>Go to <strong>YAML Custom Fields</strong> admin page</li>
<li>Enable YAML for your template (e.g., page.php)</li>
<li>Click <strong>Add Template Global</strong> to define the template global schema</li>
<li>Define fields that should have shared default values</li>
<li>Click <strong>Manage Template Global Data</strong> to set the default values</li>
</ol>
<p><strong>Using Template Global in Posts:</strong></p>
<p>When editing a post that uses a template with Template Global fields, you’ll see a dual-field interface for each field:</p>
<ul>
<li><strong>Template Global (All Pages)</strong> – Read-only display showing the default value (with Edit link)</li>
<li><strong>Page-Specific Value</strong> – Editable field for this post only</li>
<li><strong>Checkbox</strong> – “Use template global for this field” – Toggle per field</li>
</ul>
<p><strong>Benefits:</strong></p>
<ul>
<li><strong>Consistency:</strong> Set default values once, use across all posts</li>
<li><strong>Flexibility:</strong> Override any field on any post individually</li>
<li><strong>Clarity:</strong> See both global and local values side-by-side</li>
<li><strong>Efficiency:</strong> Update template global to affect all posts at once</li>
</ul>
<p><strong>Data Priority (when using template functions):</strong></p>
<p>When a field uses template global, <code>ycf_get_field()</code> returns data in this priority order:</p>
<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><strong>Page/Post data:</strong> Stored in post meta with key <code>_yaml_cf_data</code></li>
<li><strong>Template Global preferences:</strong> Stored in post meta with key <code>_yaml_cf_use_template_global_fields</code> (per-field array)</li>
<li><strong>Template Global schemas:</strong> Stored in options table with key <code>yaml_cf_template_global_schemas</code></li>
<li><strong>Template Global data:</strong> Stored in options table with key <code>yaml_cf_template_global_data</code></li>
<li><strong>Site-wide global schema:</strong> Stored in options table with key <code>yaml_cf_global_schema</code></li>
<li><strong>Site-wide global data:</strong> Stored in options table with key <code>yaml_cf_global_data</code></li>
<li><strong>Partial data:</strong> Stored in options table with key <code>yaml_cf_partial_data</code></li>
<li><strong>Schemas:</strong> Stored in options table with key <code>yaml_cf_schemas</code></li>
<li><strong>Data Object Types:</strong> Stored in options table with key <code>yaml_cf_data_object_types</code></li>
<li><strong>Data Object Entries:</strong> Stored in options table with keys <code>yaml_cf_data_object_entries_{type_slug}</code></li>
</ul>
