My website allows registered Members to add Comments to my Articles. However, before a Comment will appear, it has to be approved by me.
What is the best way to let my PHP code know that a Comment is ready to be displayed?
Currently, I have a VARCHAR(20) field where I have either "Approved" or "Pending" and my queries say...
However, I also have a field called approved_on which is a DATETIME and allows Nulls.
Would it be easier to lose the status field and just run my queries like this...
WHERE approved_on IS NOT NULL
(or whatever the proper syntax is?!)
Is it bad to have a field that is full of Nulls like that?
