Question

我遇到了这段代码的问题：

if (!empty($_POST['email']) && !empty($_POST['password'])
     && $_POST['password'] == $_POST['confirm_password']
     && ( !filter_var ($_POST['email'], FILTER_VALIDATE_EMAIL) === false ) ):
    //Enter the new user in the database
    $sql = "INSERT INTO users (email, password) VALUE (:email, :password)";
    $stmt = $conn->prepare($sql);

    $stmt->bindParam(':email', $_POST['email']);
    $stmt->bindParam(':password', password_hash($_POST['password'], PASSWORD_BCRYPT));

    if( $stmt->execute() ):
        header("Location:succRegister.php");

    else : //this part of code is the problem
        header("Location:failRegister.php");//

    endif;
endif;

?>

我希望我知道为什么当声明（$stmt）没有针对上述条件执行时，链接（else）不起作用？第一个链接确实有用。

我想我知道可能是什么问题。如果未满足您的第一个if条件，则不会到达标头。您可以将失败位置移到外部if之外，以便默认情况下将其移至那里。然后在内部if上，在发送标题后立即退出。

if (!empty($_POST['email']) && !empty($_POST['password'])
     && $_POST['password'] == $_POST['confirm_password']
     && ( !filter_var ($_POST['email'], FILTER_VALIDATE_EMAIL) === false ) ):
    //Enter the new user in the database
    $sql = "INSERT INTO users (email, password) VALUE (:email, :password)";
    $stmt = $conn->prepare($sql);

    $stmt->bindParam(':email', $_POST['email']);
    $stmt->bindParam(':password', password_hash($_POST['password'], PASSWORD_BCRYPT));

    if( $stmt->execute() ):
        header("Location: succRegister.php");   // only go here on success
        exit();
    endif;
endif;

// always go here if you haven't already gone somewhere else
header("Location: failRegister.php");

你可以用

实现同样的目标

if (!empty($_POST['email']) && !empty($_POST['password'])
     && $_POST['password'] == $_POST['confirm_password']
     && ( !filter_var ($_POST['email'], FILTER_VALIDATE_EMAIL) === false ) ) :
    //Enter the new user in the database
    $sql = "INSERT INTO users (email, password) VALUE (:email, :password)";
    $stmt = $conn->prepare($sql);

    $stmt->bindParam(':email', $_POST['email']);
    $stmt->bindParam(':password', password_hash($_POST['password'], PASSWORD_BCRYPT));

    if ( $stmt->execute() ):
        header("Location: succRegister.php");   // only go here on success
    else:
        header("Location: failRegister.php");   // $stmt->execute failed
    endif;
else:
    header("Location: failRegister.php");       // $_POST validation failed
endif;

但如果您因失败原因重定向到同一页面，则这是多余的。

php header（＆＃34; Location :)使用了两次问题
