I want to insert a question "Is fire hot or cold". If the answer is not "hot" (not case sensitive) the user must try again.

Any help will be appreciated.

MadTechie · May 21, 2008

i am not going to do it for you (you need to show some effort) but your need an input text box and some text,

if the input name is "question" then your php validation code would be

if( strtolower($_POST['question']) != "hot" )
{
echo "wrong";
}
