Auto-Upgrading users in WordPress

I made a small site recently where I wanted all newly registered users from a specific email domain to automatically be administrators (this is a terrible idea, don’t do it). The user registration was restricted by Single-Sign-On and 2-Factor Authentication, so I felt relatively safe doing this, especially since it was only a “for fun” project.

The interesting bit of code that upgraded users to admins is as follows:

add_action( 'user_register', 'upgrade_email_to_admin', 10, 1 );
function upgrade_email_to_admin( $user_id ) {
$user = get_user_by( 'ID', $user_id );
if ( false !== $user ) {
$email = $user-&gt;data-&gt;user_email;

   // Only example.com please.
    if ( false === strpos( $email, '@example.com' ) ) {
        return;
    }

    $roles = $user-&amp;gt;roles;

    if ( ! in_array( 'administrator', $roles, true ) ) {
        $user_update = array();
        $user_update['ID'] = $user_id;
        $user_update['role'] = 'administrator';
        wp_update_user( $user_update );
    }
}
Code language: PHP (php)

This is 100% insecure, please do not do this 🙂

Logging Post Status Transitions in WordPress

Last week an interesting issue came up for a client. Somehow a few posts were moved from Published to Draft. Unfortunately, post status isn’t stored in revisions so it’s unlikely we’ll ever know who or how it happened. Luckily there’s a simple solution I found to log all post status transitions in post meta:

add_action( 'transition_post_status', 'log_post_transition', 10, 3 );
function log_post_transition( $new_status, $old_status, $post ) {
if ( 'post' === $post-&gt;post_type ) {
$current_user = wp_get_current_user();
add_post_meta( $post-&gt;ID, '_post_status_log', sprintf( '%s %d, %s-&gt;%s', current_time( 'mysql' ), $current_user-&gt;ID, $old_status, $new_status ), false );
}
}Code language: PHP (php)

Validating WordPress attachments with WP-CLI

I recently worked on migrating a site to a different server and for one reason or another, some of the images did not come over properly. While I could have just re-downloaded and re-imported all of the media, it would have taken quite a while since the media library was well over 100Gb. Instead, I opted to use WP-CLI to help find what images were missing:
