multidim array passed from HTTP_POST_VARS

Hello phreaks I have a form and I pass all the values that are submitted thru HTTP_POST_VARS to a function "update_lesson($id, $frm)" (all HTTP_POST_VARS go into $frm array). My question is: what happens if you are already passing an array (from the form "preq[]")...does $frm automatically handle the array? Does it become $frm["preq"][x], where x is a numerical key? My problem is that I need to update multivariate values and I don't know how to address them to be able to send them to the db. I dont know if this is clear enough but here is the code: case "update" : update_lesson($id, $HTTP_POST_VARS); print_lesson_list(); break; //this calls the function and passes it the values from the form //here is the function that handles the update: function update_lesson($id, $frm) { //this is just the part that updates the multivariate array while (list ($key, $val) = each ($frm["glenum"][])) { $qid = db_query(" INSERT INTO lesson_gle (l_id, glenum) VALUES ('$id', '$val') "); } I know the above wont work...but how do I traverse this array? -------------------------------------------------- Luis Muench luis@mecha.barry.edu Project MECHA Webmaster (305)899-3626
