<p>Strict Permalinks does two things:</p>
<ol>
<li>Restricts the <code>post_name</code> portion of the permalink to alphanumerics and hyphens</li>
<li>Disables permalink editing once a post is published</li>
</ol>
<p>Like me, you may have been under the impression that post slugs are already restricted to alphanumerics and hyphens. In the current WordPress 2.8.5, a title that includes certain kinds of punctuation (e.g., “smartquotes”) will result in URL-encoded characters in the <code>post_name</code> field. Many browsers handle this oddity seamlessly, however this may cause difficulties when integrating with systems expecting a more limited URL syntax.</p>
<h3>Upgrade</h3>
<ol>
<li>Use the plugin updater in WordPress or…</li>
<li>Delete the previous <code>strict-permalinks</code> folder from the <code>/wp-content/plugins/</code> directory</li>
<li>Upload the new <code>strict-permalinks</code> folder to the <code>/wp-content/plugins/</code> directory</li>
</ol>
<h3>Usage</h3>
<ol>
<li>In all cases the <code>post_title</code> to <code>post_name</code> conversion (i.e., the <code>sanitize_title</code> filter) will be limited to a-z, 0-9 and hyphens (-).</li>
<li>If a post is not yet published, the permalink can be edited as usual.</li>
<li>Once a post is published, the permalink editing interface is disabled.</li>
</ol>


Strict Permalinks

Restricts permalink syntax and disables permalink editing after a post is published.

</blockquote>
<h3>Advanced Filters</h3>
<p>For developers who need more control, Custom Permalink Editor provides several filters to customize its behavior.</p>
<h4>Add PATH_INFO in $_SERVER Variable</h4>
<p>Enable PATH_INFO support in the $_SERVER variable. This is useful for certain server configurations.</p>
<p><strong>Usage:</strong></p>
<pre><code>add_filter( 'cp_editor_path_info', '__return_true' );
</code></pre>
<h4>Exclude Specific Permalinks</h4>
<p>Prevent specific permalinks from being processed by the plugin. Useful for excluding system files like sitemaps or special pages.</p>
<p><strong>Example:</strong> Exclude sitemap.xml from processing</p>
<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>
<p>Remove the Custom Permalink Editor form from specific post types. Helpful if you want to disable the feature for certain content types.</p>
<p><strong>Example:</strong> Exclude a custom post type called ‘custompost’</p>
<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>
<p>Exclude individual posts or pages from showing the Custom Permalink Editor form. You can filter by ID, template, or any post property.</p>
<p><strong>Example:</strong> Exclude post with ID 1557</p>
<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>
<p>By default, the plugin removes accents from permalinks for better URL compatibility. Enable this filter if you need to preserve accented characters.</p>
<p><strong>Usage:</strong></p>
<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>
<p>By default, permalinks are converted to lowercase. Use this filter to preserve capital letters in your custom URLs.</p>
<p><strong>Usage:</strong></p>
<pre><code>function team_kcg_allow_capitals() {
  return true;
}
add_filter( 'cp_editor_allow_caps', 'team_kcg_allow_capitals' );
</code></pre>
<p><strong>Note:</strong> Add these code snippets to your theme’s <code>functions.php</code> file or use a custom plugin/code snippets plugin.</p>
<h3>How To Use</h3>
<p><strong>Changing a Post or Page Permalink:</strong></p>
<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>
<p><strong>Example:</strong><br />
– Default URL: <code>yoursite.com/2026/01/11/my-blog-post/</code><br />
– Custom URL: <code>yoursite.com/seo-friendly-custom-url/</code></p>
<p><strong>Reverting to Default Permalinks:</strong></p>
<p>Simply deactivate the plugin and all posts will automatically revert to WordPress default permalink structure.</p>
