Undefined variable: wpdb

    Hello,

    I’m writing a plugin and trying to request some data from a custom table in my database using:

    $current_text = $wpdb->get_results("SELECT text FROM addtext ORDER BY id DESC LIMIT 1");

    but just get the error Undefined variable: wpdb

    Any idea why this isn’t working? I’ve follow the docs and scoured Google, with no luck. Still pretty new to WP plugins so probably something obvious.

    Thanks!

    This is a plugin, and not outside of wordpress so I shouldn’t need to include any other files.

    No idea why this doesn’t work.

    Any ideas?

    I needed to add global $wpdb; in my function.
