I've got a problem with a form that I've made. Basically the form loads a number of textboxes based on how many columns are in a table. I don't have any problems doingthat, but on the next page I'm trying to put the textbox values into a string variable using $str &= $_POST['txt'.$i].
It goes through a loop which should gather the textbox value and add it to a string, but when I display the string after it has done this, it displays nothing.
Any help is much appreciated :)
