php echo

Sep 24th, 2008

Hi all,

This is going to seem a very basic sort of question so here goes....
i have a form with a couple of checkboxs and what i want to do is
echo the selected checkbox. for example;

if checkbox 1 is submitted then an image will be shown in a div underneath the form when it is submitted.
and if option 2 is selected then a differnt image will be shown and so on and so on.
all in the same page without redirecting and so on.

thanks in advance...

Cheers...

Re: php echo

Thanks Robbob, thats pretty much on the money. however...

firstly im an idiot, i wanted radio buttons not checkboxes. we wont even go there!

Secondly, could we have it where each radio button has a different outcome? so if 1 is selected img 1 shows if the second button is selected then img 2 is shown...

Thanks again

Cheers...

This seems to work OK, just put your images in a folder under the document root called "rdo" and name your images to be the same as the value of the radio button, just replace the spaces with underscores.
