jesus christ if i had a dollar every time someone submitted unsanitized database code here I wouldn't need a job. give me the url so I can steal your database and sell it to spammers once you are done kkthx — skrilled, Dec 03 '13 at 23:34

I hope this is not production code because code has potentional SQL-injection (please check this What is SQL injection?). But anyway regarding your question. You need add simple checking for achieving what you want:

    ...

    if($business_name == ''){
       echo"<script>alert('please enter the usernme')</script>";
       exit();
       }
    if($email == ''){
       echo"<script>alert('please enter the email')</script>";
       exit();
       }

    //check for matching
    if($email != $emailagain){
       echo"<script>alert('entered email addresses don't match')</script>";
       exit();
       }
    $check_email = "SELECT * FROM ... where ...='$...'";
    ...

So please post your solution and choose proper best answer. – Alexander Myshov Dec 04 '13 at 12:45 — Alexander Myshov, Dec 04 '13 at 12:45
