!preg_match question?

[PicnicTutorials]

Hello, I'm stuck. I'm cleaning my email with this below. But I don't want it to run an error if the field is left blank. In other words, I want to clean it "if" stuff is input, but I also want it to send if there is nothing input. Currently it won't send the form if no input. How to edit? Thanks!

 

// Clean Email

if (!preg_match("/^[A-Z0-9._%-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$/i",$email)) {

header( "Location: $errorurl" );

exit ;

}

   header( "Location: $errorurl" );
   exit ;
}

Thanks Jim! But no go. It runs this error? I sure it's just missing some stupid symbol or something...

 

Fatal error: Call to undefined function isblank()

Uggg!

 

try !empty($email)

isblank() is NOT a PHP function

Uggg!

 

try !empty($email)

 

Thank you very much Jim - that worked perfect! Have a nice holiday!
