Process array after form submission problem

Hi, My problem is that I have a dynamic form with vars which I want to process. The variables are checkbox names with a variable number of checkboxes but all currently have the same variable name. ie. <form action='process.php' method='post'> <input type = text name = user value = name> <input type = checkbox name = grant value = "{$array["code"]}"> <input type = checkbox name = grant value = "{$array["code"]}"> <input type = checkbox name = grant value = "{$array["code"]}"> The array code works fine in that the values reflect what is in the DB. I understand that $grant will be an array? (am I right?) so how do I use PHP to look at $grant as an array in my processing script rather than an ordinary variable? I can get the DB to update if there is only one checked box but otherwise it updates the DB with the value of the last checkbox. Any ideas? Steve Jackson
