こんにちは私はPDOを使用するためにmysqliphpファイルをどのように移行するのか疑問に思いました。誰かが私のコードを見て、私が正しい方向に進んでいるかどうかを確認できますか?
これは私の元の(mysqli)コードです:
<?php
// connecting to database
$conn = new mysqli('xxxxxx', 'xxxxxx', 'password', 'xxxxxx');
$match_email = 'email';
$match_passhash = 'passhash';
if (isset($_POST['email'])) {
$clean_email = mysqli_real_escape_string($conn, $_POST['email']);
$match_email = $clean_email;
}
if (isset($_POST['passhash'])) {
$clean_passhash = mysqli_real_escape_string($conn, $_POST['passhash']);
$match_passhash = sha1($clean_passhash);
}
$userquery = "SELECT email, passhash, userlevel, confirmed, blocked FROM useraccounts
WHERE email = '$match_email' AND passhash = '$match_passhash'
AND userlevel='user' AND confirmed='true' AND blocked='false';";
$userresult = $conn->query($userquery);
if ($userresult->num_rows == 1) {
$_SESSION['authorisation'] = 'knownuser';
header("Location: userhome.php");
exit;
} else {
$_SESSION['authorisation'] = 'unknownuser';
header("Location: userlogin.php");
exit;
}
?>
そして、これはそれをPDOに移行する私の試みです:
<?php
// connecting to database
$dbh = new PDO("mysql:host=xxxxxx; dbname=xxxxxx", "xxxxxx", "password");
$match_email = 'email';
$match_passhash = 'passhash';
if (isset($_POST['email'])) {
$clean_email = mysqli_real_escape_string($conn, $_POST['email']);
$match_email = $clean_email;
}
if (isset($_POST['passhash'])) {
$clean_passhash = mysqli_real_escape_string($conn, $_POST['passhash']);
$match_passhash = sha1($clean_passhash);
}
$userquery = "SELECT email, passhash, userlevel, confirmed, blocked FROM useraccounts
WHERE email = ':match_email' AND passhash = ':match_passhash' AND
userlevel='user' AND confirmed='true' AND blocked='false';";
$stmt = $dbh->prepare($query);
$stmt->bindParam(":match_email", $match_email);
$stmt->bindParam(":match_passhash", $match_passhash);
$stmt->execute();
$userresult = $conn->query($userquery);
if ($userresult->num_rows == 1) {
$_SESSION['authorisation'] = 'knownuser';
header("Location: userhome.php");
exit;
} else {
$_SESSION['authorisation'] = 'unknownuser';
header("Location: userlogin.php");
exit;
}
?>
また、PDOで返される行数をカウントする方法もわかりません。
誰かが私を助けることができれば、それは非常に素晴らしいことです。
よろしくお願いします!
