form validation, minimum characters

[oshjosh]

Hi,

Im pretty new to PHP, however I have a form that submits data to a mysql database, I would like to specify the minimum amount of characters that have entered into one field before the form can be submited, If any one can show me in simple terms I would be very grateful.

Cheers
Rob

before the form can be submited
Then it's done on the client side, hence PHP isn't involved. But, you should always have PHP do input validation to. Something like [tt]if (strlen($_POST['fieldName']) > $limit)[/tt] would seem to be sufficient for you. //Daniel
