    <p>Since you run custom scripts to manipulate the database, why don't you change the slug as well? I'm using a nice function for that:</p> <pre><code>function url_slug($str, $options = array()) { // Make sure string is in UTF-8 and strip invalid UTF-8 characters $str = mb_convert_encoding((string)$str, 'UTF-8', mb_list_encodings()); $defaults = array( 'delimiter' =&gt; '-', 'limit' =&gt; 100, 'lowercase' =&gt; true, 'replacements' =&gt; array(), 'transliterate' =&gt; false, ); // Merge options $options = array_merge($defaults, $options); $char_map = array( // Latin 'À' =&gt; 'A', 'Á' =&gt; 'A', 'Â' =&gt; 'A', 'Ã' =&gt; 'A', 'Ä' =&gt; 'A', 'Å' =&gt; 'A', 'Æ' =&gt; 'AE', 'Ç' =&gt; 'C', 'È' =&gt; 'E', 'É' =&gt; 'E', 'Ê' =&gt; 'E', 'Ë' =&gt;

    1. COI don't, I'm a bit of a "noob" when it comes to this sort of stuff. I was kinda hoping there was a way I can run a sql query to "update" all posts so that it automatically generates the slug. At the moment, I can only update 20-30 manually through the wp-admin section.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
