You may want to try this PHP form generation class that lets you specify a message in a Javascript dialog that asks the user if he really wants to submit the form again. Usually nervous users submit the forms more than once because they don't want to wait. This class would help in that aspect. http://phpclasses.UpperDesign.com/browse.html/package/1 This would not prevent the user to submit the form more than once deliberately. If you really want to prevent that what is usually done is to have a create a random key that is stored in a database and is passed in the form as an hidden field. Once the form is submitted the key is cleared from the database. Next time the form is submitted you may verify that the key does not exist and not process the form. Manuel Lemos
