*OK, more eval for today

I know, it's eval = evil, but I don't see any other way I can check for 120 variables submitted via post, without making a temp variable, assigning a value of the posted Var and checking for it (and deciding on the further run of the script). Anyways, I took a classical eval thing and am doing fine with it. It looks like this: $temp = "\$php_q3_".$i; // $i is a loop index eval ("\$temp = \"$temp\";"); works alright. Now, how do I eval directly from the $HTTP_POST_VARS? I am trying to do this: $tempVar1 = '\$HTTP_POST_VARS[\"q4_'.$i.'"]'; eval("\$tempVar1=\"$tempVar1\";"); and am obviously failing. If you know any other way to validate 120-150 variables in a loop and then rewrite the values into the fields (checkboxes, radios and selects) - should an error had been made - let me know. Best Regards, Alex p.s. you do help! :)
