Making Sure at least 1 box is checked

[bjblackmore]

Hi,
I have 15 checkboxes, and I want to make sure someone checks at least one of them. Is there someway i can do if (!radiobutton[]) rather than having to type out all 15 radiobuttons
if (!$radiobutton1 || !$radiobutton2 || !$radiobutton3 || !$radiobutton4 || !$radiobutton5.......)
Cheers
Ben

No.
If you have created 15 different radiobuttons then you will have to check all 15 seperately.

This may not be what you want, but you could set one as checked default:

<input type=radio name=name value=value checked>

If you put checked inside the html tag for one of the, that one will be checked when the page is loaded.

If they really are called checkbox1, checkbox2 etc... you can.

I've got a page with dynamically generated checkboxes on, named game[#number], ie game1, game2, game3 etc...

I check it like the below...

for ($i=0;$i<=$results-1;$i++) {
if ("${"game".$i}" != "") {$selected = 'Y';}
}
if ($selected != 'Y') {echo "You must select at least one checkbox"; exit;}

So as soon as one is selected, $selected is set to Y, and it runs fine, if none are selected, $selected isn't set to Y, and it gives an error and exits.

Hope that helps.
