Question

Right now i have this for full name:

if(empty($_POST['full_name']) || strlen($_POST['full_name']) < 4)
{
$errormessage[] = "ERROR.\n";
}

How can i make a validation for full name, so the entered name should contain space?

So like if person enter:

John Andersson

Its ok, but if he enter:

JohnAndersson

its not ok, error. So you would need a “space” in your fullname.

Like this:

if (strpos(trim($_POST['full_name']), ' ') !== false){
  // user has specified first and last name
}
elseif (strpos(trim($_POST['full_name']), ' ') !== true){
  // user has specified a single name
}

You need to enter the trim function to check for bad names such as:

• Justin Alba[space]
• [space]Justin Alba
• Justin[space]
• [space]Justin
