Error when classes is blank

  • This seems very useful, well done. I was looking for a way to support <mark>.

    When I set up a new formatting option with Type Value of mark, no classes are necessary to add.

    After saving settings, the plugin echos the following error into the table…

    Undefined index: classes in /Users/myname/Local Sites/the-map/app/public/wp-content/plugins/tinymce-custom-styles/tinymce-custom-styles.php on line 631

    Only adding an arbitrary class name , eg. “none“, removes the error. But I don’t need to use any classes.

    Looks like you need to properly check whether the user has added classes.
