I just updated my blog to the latest version of WordPress.

All seemed fine until I had a look at the site. Some of my menus had went a little weird.

Quite a few of the titles had changed to ellipses! I went into the dashboard and changed them back, my changes didn’t stick. I presumed that it must have been the upgrade. I had no idea where to start so shot off a quick tweet for help.

After dinner I calmed down a little and though about the changes to my blog I’d made recently for mico blogging. One of those was to give posts without a title titles on wp_insert_post_data. It uses ellipse! This was meant for posts arriving from the micro.blog app. They would get titles set when they arrived on my blog, to prevent ugliness in he dashboard.

function modify_post_title($data)
{
    if ($data[ 'post_title' ] == ''  ) {
        //wp_filter_nohtml_kses strips html and then I replace   
        $title = str_replace( " " , " " , substr( wp_filter_nohtml_kses( $data[ 'post_content' ] ) , 0, 60 ) ) . "..." ;
        $data['post_title'] =  $title ;
    }
    return $data; // Returns the modified data.
} 

so I’ve changed the if to:
if ($data[ 'post_title' ] == '' && $data[ 'post_type' ] == 'post' )

Which seems to have solved the problem and taught me a lesson.
