简单的preg表达式，根据空间将名称剥离为2个部分[关闭]

Question

I have a form field called 'Name' - but I'd like to save the submission into the DB as First Name & Last Name using a preg expression.

Can some illustrate how if I entered the name 'John Smith' into the field a regexp would strip this into First Name - John Surname - Smith

Thanks in advance

Answer 1

Prefer use split (version php < 5.3.0) or explode which is an alias of split function, in your case, you just have to split you fullname with space character ' '

var $fullname = "John Smith";
var $splitfullname = $fullname.split(' ');

var $firstname = $splitfullname[0];
var $lastname = $splitfullname[1];

-

var $fullname = "John Smith";
var $splitfullname = explode(' ', $fullname);

var $firstname = $splitfullname[0];
var $lastname = $splitfullname[1];

if you build the form that catch firstname and fullname, I will suggest you to split your fullname input field into two input field (firstname and lastname).
