input: type=checkbox...?

[brickuz]

This worked in ASP but not i PHP:

input type=checkbox name=whatever

s_whatever = form(whatever)
if whatever = "on" then ... else ...

In PHP I get a "Undefined index: whatever" when I leave the checkbox unchecked, I guess that's because the checkbox returns a "empty value" but how do I fix it? How do you get the checkbox to return a correct value?

Hmm, I hope you understand the problem... and my "ASP/PHP/Pascal/C++/Java/HTML -code" 🙂

Hi Erik,

Assuming you use input type=checkbox name=whatever then you can verify if whatever is checked or not like this:

if($_POST[whatever] == "ON")
{
   Do Stuff
}
else
{
   Do something else
}

This is if the form method is POST of course otherwise use $_GET[whatever] instead.

Best wishes,
Simon.

Thx alot, you got around the problem abit better than me (I tried to fill a variable with "whatever" but when whatever is empty I get a errormessage... by using the "if" you get around that problem... and some people call me smart... THEY must be dumb...)
