Post excerpt in custom meta box… help with proper php format

The only custom form field that you seem to be printing out is a text input named “excerpt”. In your processor script you are checking for a $_POST var named “_ideas_quicknote”. Since it is not actually sent in the POST request, your processor will never see it. Please try the following:

<?php
print "\n" . '<h3>Basics</h3>';
print "\n" . '<input type="text" name="_ideas_quicknote" id="myplugin_ideas_quicknote" value="' . esc_attr( $quicknote )  . '"/>';
