I see two ways to solve this problem: changing the data that forms the author URL, or changing the author URL. You probably should handle redirects too, so old URLs to user archives keep working when a user changes their nickname. Changing the author URL There are two parts to this question: handle incoming links … Read more
Yes, it is possible. Sample code, has to be tested and refined: // get all posts $posts = get_posts( array ( ‘numberposts’ => -1 ) ); foreach ( $posts as $post ) { // check the slug and run an update if necessary $new_slug = sanitize_title( $post->post_title ); if ( $post->post_name != $new_slug ) { … Read more
For some sites in German I use the following plugin to translate page to seite (the German word for page): <?php # -*- coding: utf-8 -*- /** * Plugin Name: T5 Page to Seite * Description: Ersetzt <code>/page/</code> durch <code>/seite/</code>. * Author: Fuxia Scholz * License: MIT * License URI: http://www.opensource.org/licenses/mit-license.php */ if ( ! … Read more
I just went and tested this (WP 3.3.1), the wordpress core will automatically do a redirect if you change the post slug, even if you change the slug from post-a to post-b and then to post-c, post-a will return a 301 to post-c. That said, the redirection plugin that Mike Jolley recommended is an outstanding … Read more
I wouldn’t try to localize your slugs. Instead, why not give your users the option to change them by adding another field to the permalink settings page? Hook into load-options-permalink.php and set up some things to catch the $_POST data to save your slug. Also add a settings field to the page. <?php add_action( ‘load-options-permalink.php’, … Read more
The string used in WordPress to identify the plugin is: plugin_basename($file); … where $file is a file with the plugin headers. So if you are in your plugin, get the slug with: $slug = plugin_basename( __FILE__ );
As per @SinisterBeard‘s very valid comment to the question already a couple of years back now, this answer has long been outdated and the mentioned function(s) hence been replaced by a newer API: See wp_unique_post_slug. Original Answer Off the bat, I can’t give you a page/tutorial/documentation on how WP slugs are generated, but take a … Read more
You are almost there. The function you need is sanitize_title_with_dashes( $title )
Yes, this is possible, but if the plugin is creating a custom post type using the rewrite => array(‘slug’ => ‘post_type’) parameter, then it’s not likely that you’re going to be able to replace the slug. Whenever custom post types are created, URL rewrite rules are written to the database. Depending on which action triggers … Read more
The function you are looking for is get_term_by. You would use it as such: <?php $term = get_term_by(‘slug’, ‘my-term-slug’, ‘category’); $name = $term->name; ?> This results in $term being an object containing the following: term_id name slug term_group term_taxonomy_id taxonomy description parent count The codex does a great job explaining this function: https://developer.wordpress.org/reference/functions/get_term_by/
