등록시 자격 증명 복제

Question

누구든지 내 코드가 내 테이블에 등록 자격 증명을 두 번 삽입하는 이유를 볼 수 있습니까? action_registration.php. 나는 현재 로그인을 더 안전하게하는 법을 배우고 있는데, 등록을위한 입력이 테이블에 두 번 삽입되었다는 것을 알아 차렸다.

<?php 

if (isset($_POST['register'])){ 

// connection handler link 
$conreg = new mysqli('localhost', 'x', '123456', 'db.x.x'); 

// in case theres no link to connection 
if (mysqli_connect_error()){ 
    echo mysqli_connect_error(); 
    exit(); 
} // end error if 

else // when connection is okay 
{ 
    echo "we good on connection so far"; 
    echo "<br>"; 

}  // end else connection okay 

$userreg = $_POST['username']; 

$passreg =$_POST['password']; 
$phash = sha1(sha1($passreg."salt")."salt"); 

$emailreg = $_POST['email']; 

$sqlreg = "INSERT INTO tbl1 (`username` , `password`, `email` , `comment_value`, `Member_Since`) VALUES (?,?,?,'1' , now()) "; 

// prepare link, and function statement 
$stmtreg = $conreg->prepare($sqlreg); 

// bind variable parameters 
mysqli_stmt_bind_param($stmtreg, "sss", $userreg , $phash , $emailreg); // bind variables s' is a string for username , s' is a string for password 

if (!mysqli_execute($stmtreg)) 
{ 

echo "Died on bind variable parameters"; 
die('stmt error: '.mysqli_stmt_error($stmtreg)); 

} // end error if 

mysqli_stmt_execute($stmtreg); //excute the preapared register statement 

//$cookie_value = $user; 
//setcookie($cookie_name , $cookie_value, time() + (2000), "/"); 

    //header("Location: reg_.php"); 
    echo '<font color="green">Please Login Now</font>'; 

} // end isset register 

?> 

양식은 action_registration.php 호출

<table> 
<form action ="actions/action_registration.php" method="POST" > 
<tr> 
<td> Username :</td> 
    <td><input type="text" placeholder="Username" id="username" name="username"> </td> 
    </tr> 

    <tr> 
    <td>Password :</td> 
    <td><input type="password" placeholder="Password" id="password" name="password" > </td> 
    </tr> 

    <tr> 
    <td> Email :</td> 
    <td><input type="text" placeholder="Email"id="email" name="email" size="20"/></td> 
    <br/> 
    </tr> 
    <tr> 
    <td><td> 
    <input type="submit" name="register" value="Register"></td> </tr> 
    </table> 
    </form> 

Answer 1

당신은 두 번 쿼리를 실행됩니다

if (!mysqli_execute($stmtreg)) //<--here 
{ 

echo "Died on bind variable parameters"; 
die('stmt error: '.mysqli_stmt_error($stmtreg)); 

} // end error if 


mysqli_stmt_execute($stmtreg); //<-- and here 

당신은 단순히 두 번째 전화를 놓을 수 있습니다. http://php.net/manual/en/function.mysqli-execute.php
