<h3>Advanced Filters</h3>
For developers who need more control, Custom Permalink Editor provides several filters to customize its behavior.
<h4>Add PATH_INFO in $_SERVER Variable</h4>
Enable PATH_INFO support in the $_SERVER variable. This is useful for certain server configurations.
Usage:
<pre><code>add_filter( 'cp_editor_path_info', '__return_true' );
</code></pre>
<h4>Exclude Specific Permalinks</h4>
Prevent specific permalinks from being processed by the plugin. Useful for excluding system files like sitemaps or special pages.
Example: Exclude sitemap.xml from processing
<pre><code>function team_kcg_exclude_permalink( $permalink ) {
 // Check if permalink contains 'sitemap.xml'
 if ( false !== strpos( $permalink, 'sitemap.xml' ) ) {
 return '__true';
 }

 return;
}
add_filter( 'cp_editor_exclude_permalink', 'team_kcg_exclude_permalink' );
</code></pre>
<h4>Exclude Specific Post Types</h4>
Remove the Custom Permalink Editor form from specific post types. Helpful if you want to disable the feature for certain content types.
Example: Exclude a custom post type called ‘custompost’
<pre><code>function team_kcg_exclude_post_type( $post_type ) {
 // Replace 'custompost' with your actual post type name
 if ( 'custompost' === $post_type ) {
 return '__true';
 }

 return '__false';
}
add_filter( 'cp_editor_exclude_post_type', 'team_kcg_exclude_post_type' );
</code></pre>
<h4>Exclude Specific Posts</h4>
Exclude individual posts or pages from showing the Custom Permalink Editor form. You can filter by ID, template, or any post property.
Example: Exclude post with ID 1557
<pre><code>function team_kcg_exclude_posts( $post ) {
 // Exclude specific post by ID
 if ( 1557 === $post->ID ) {
 return true;
 }

 // You can also exclude by other criteria
 // Example: Exclude posts with a specific template
 // if ( get_page_template_slug( $post->ID ) === 'template-landing.php' ) {
 // return true;
 // }

 return false;
}
add_filter( 'cp_editor_exclude_posts', 'team_kcg_exclude_posts' );
</code></pre>
<h4>Allow Accented Characters</h4>
By default, the plugin removes accents from permalinks for better URL compatibility. Enable this filter if you need to preserve accented characters.
Usage:
<pre><code>function team_kcg_allow_accents() {
 return true;
}
add_filter( 'cp_editor_allow_accents', 'team_kcg_allow_accents' );
</code></pre>
<h4>Allow Capital Letters</h4>
By default, permalinks are converted to lowercase. Use this filter to preserve capital letters in your custom URLs.
Usage:
<pre><code>function team_kcg_allow_capitals() {
 return true;
}
add_filter( 'cp_editor_allow_caps', 'team_kcg_allow_capitals' );
</code></pre>
Note: Add these code snippets to your theme’s <code>functions.php</code> file or use a custom plugin/code snippets plugin.
<h3>How To Use</h3>
Changing a Post or Page Permalink:
<ol>
<li>Navigate to Posts > All Posts (or Pages > All Pages)</li>
<li>Click on the post/page you want to edit</li>
<li>Scroll down to find the “Custom Permalink Editor” meta box</li>
<li>Enter your desired custom URL in the text field (without the domain)</li>
<li>Click “Update” or “Publish” to save your changes</li>
<li>Visit your post to see the new permalink in action!</li>
</ol>
Example: 
– Default URL: <code>yoursite.com/2026/01/11/my-blog-post/</code> 
– Custom URL: <code>yoursite.com/seo-friendly-custom-url/</code>
Reverting to Default Permalinks:
Simply deactivate the plugin and all posts will automatically revert to WordPress default permalink structure.
