Incorrect integer value: '' for column

[brad]

You can add a default of now to your Post Value. This will force a null value if there is no input value.

Note: When you add. this using the UI it adds single quotes around 'null'. You have to manually remove the single quotes.

Setting a value to NULL?

I have a form that has a hidden form field that I would like its value to be NULL. I can leave it blank and it removes any data in that field but I need the data to be entered into the database as NULL so that my filtering works as I need. Or is there a better way to enter NULL data when a form is submitted?
