Module development and code questions

Hi,

Trying to create an attendance system using webform for a school. Users are registered through a webform entity with student details- firstname, surname, dob, etc.

To create an attendance logging system - Likert scale columns with Present, Late, Absent seems sensible - but I have not been able to use any entity reference list (views of webform submissions - firstname surname) to populate the likert options values.

For example, I have seen that if an image media is used in a custom field of a taxonomy, the row in the database table continues to exist after the corresponding media has been deleted, even after the Cron has been executed.

So I looked for the media delete form (media_delete_form) and tried a simple hook to add my own validation.

Hi, in form alter I programmatically assign the value to the entity in this way
