RE: [PHP] Re: Dynamically check radio buttons

It looks like your code could use "variable variables" to help you out. ::::::::::: OLD CODE :::::::::::::::: > > for ($GameIdx = 1; $GameIdx <= 17; $GameIdx++) { > > /* instead "hardcoding each radio button name - just do it > programmatically > > by concatenating / creating the name */ > > $frmGame = "Game" + $GameIdx; > > if ($frmGame) { ::::::: END OF OLD CODE ::::::::::::: ** this check will always be true - because you just set $frmGame equal to a value... *** What you want to do at this point is use variable variables (where the variable name is actually a variable itself. ::::::::: NEW CODE ::::::::::: > > $var_frmGame = "Game" + $GameIdx; > > $frmGame = $$var_frmGame; // The "$$" is used for variable variables > > if ($frmGame) { :::::: END OF NEW CODE ::::::: ** the above snippett is was I wrote to show the results of the dynamic (looped-through) variable $Game1, $Game2, ... I use this method when the number of form elements is variable. Instead of hardcoding the number "17" you might make a variable in the incoming form with the count of form elements (simply increment a variable with each printing of the form variable... then at the end of the form make <input type="hidden" name="elementcount" value="$count">) Then you can make the above for-statement look like this: > > for ($GameIdx = 1; $GameIdx <= $elementcount; $GameIdx++) { Does any of this make sense or help in any way? -Mark
