It's possible for a malicious user to change the values of hidden fields. Depending on the situation, this may or may not be acceptable. The code will make sure that only an admin user can change the value of this field. Replace 25 with the ID of the field that you want to limit and replace 'No' with the default value that you would like to force when a new entry is created.

Use this code to programmatically add an "alt" to files uploaded in a Formidable form. The "alt" will use the name of the uploaded file.

This example requires users to be logged in when they submit entries.

NOTE: You may need to customize this code to work for your timezone
