initialize varaibles

[greggustin]

I want to preset variables in case users leave certain fields blank in a html form
eg $email='[email protected]';
then php has the following:
$Email=$_POST['Email'];
echo "Email : ".$Email."<p>";
if the user leaves the field empty, I want it to echo
[color=red]Email: [email protected][/color]
BUT
it does this -->
[color=red][font=Verdana]Email:          [/font][/color]
(ie nothing)
soooooooooo, am I stuck doing a IF test for each post?
that is, if post is empty, then set the variable to the desired default value?

[code]
if(!$Email){
$Email = "[email protected]";
};
