Registration Form Works but shows error

I made a registration form. it actually works but it shows the Failed To Register, Try Again message. Heres my code. HTML and PHP DOCTYPE html html head titleRegistertitle head body form action methodPOST h3Registerh3 Username: input typetext nameunamebr Password: input typepassword namepassbr input typesubmit namebtn form body html php if isset_POSTbtn username _POSTuname; password _POSTpass; mysql_connectlocalhost,root,; mysql_select_dblogin2; query INSERT INTO users VALUES ,username,password; mysql_queryquery; echo Registered Successfully; else echo Failed To Register, Try Again;

You can check the post. if _SERVERREQUEST_METHOD POST Also add uname and pass control.

php if isset_POSTuname empty_POSTuname isset_POSTpass empty_POSTpass username _POSTuname; password _POSTpass; ............................ else echo Failed To Register, Try Again;
