알림 메일을 보내기 전에 PHP 등록 유효성 확인

Question

PHP 등록 시스템을 구축 중입니다. 내 웹 사이트에 새로운 사용자가 등록되면 알림 이메일을 보내드립니다. 그러나 문제는 사용자가 아무 것도 입력하지 않으면 나에게도 이메일을 보냅니다. 이 문제를 어떻게 극복합니까?

유효성 검사 부분입니다.

/*Validation Begins*/ 
if(empty($_POST) === false) { 
     $required_fields = array('school_name', 'mailing_address', 'postcode', 'courier_address', 'courier_postcode', 'courier_postcode', 'phonenumber', 'faxnumber', 'email', 'website', 'principal_fullname', 'principal_phonenumber', 'principal_email'); 
     foreach($_POST as $key=>$value){ 
      if(empty($value) && in_array($key, $required_fields) === true){ 
       mysql_close(); 
       ?> 
       <script type="text/javascript"> 
       alert("Fields marked with an asterisk are required"); 
       history.back(); 
       </script> 
       <?php 
      } 
    } 

아래는 삽입 기능과 메일 기능입니다.

function register_school($register_data){ 
$fields = '`' . implode('`, `', array_keys($register_data)) . '`'; 
$data = '\'' . implode('\', \'', $register_data) . '\''; 

mysql_query("INSERT INTO `schools_info` ($fields) VALUES ($data)"); 

    ?> 
    <script type='text/javascript'> 
    alert("Registration Successful!"); window.location.href = '/registration-success/'; 
    </script> 
    <?php 
    $schoolname = $_POST['school_name']; 
    $mailing_address = $_POST['mailing_address']; 
    $postcode = $_POST['postcode']; 
    $courier_address = $_POST['courier_address']; 
    $phonenumber = $_POST['courier_postcode']; 
    $faxnumber = $_POST['faxnumber']; 
    $email = $_POST['email']; 
    $website = $_POST['website']; 
    $principal_fullname = $_POST['principal_fullname']; 
    $principal_phonenumber = $_POST['principal_phonenumber']; 
    $principal_email = $_POST['principal_email']; 

    $to = "example@hotmail.com"; 
    $subject = "New Registered School"; 
    $message = "School Name: $schoolname\r\nSchool Address: $mailing_address\r\nPostcode: $postcode\r\nCourier Address: $courier_address\r\nCourier Postcode: $courier_postcode\r\nPhone Number: $phonenumber\r\nFax Number: $faxnumber\r\nEmail: $email\r\nWebsite: $website\r\nPrincipal Name: $principal_fullname\r\nPrincipal Phone Number: $principal_phonenumber\r\nPrincipal Email: $principal_email"; 
    $from = "testing.com"; 
    $headers = "From:" . $from; 
    mail($to,$subject,$message,$headers); 

}

:

$to = "example@hotmail.com"; 
    $subject = "New Registered School"; 
    $message = "School Name: $schoolname\r\nSchool Address: $mailing_address\r\nPostcode: $postcode\r\nCourier Address: $courier_address\r\nCourier Postcode: $courier_postcode\r\nPhone Number: $phonenumber\r\nFax Number: $faxnumber\r\nEmail: $email\r\nWebsite: $website\r\nPrincipal Name: $principal_fullname\r\nPrincipal Phone Number: $principal_phonenumber\r\nPrincipal Email: $principal_email"; 
    $from = "testing.com"; 
    $headers = "From:" . $from; 
    mail($to,$subject,$message,$headers); 

가 시작됩니다. 변수가 비어 있거나 없으면 모든 변수를 확인하십시오.

// 편집 : 죄송합니다. 값에 대한 배열이 없습니다. .. + 당신이 DB에 INSERT, 출력 JAVASCRIPT를 만들기 위해 1 개 기능을 사용해서는 안 모든

$success = true; 
foreach($register_data as $data) { 
    if (empty($_POST[$data])) { 
     $success = false; 
     break; 
    } 
} 

if ($success == true) { 
    //then mail
