Di posting ini, kita akan melihat contoh untuk belajar bagaimana memulihkan kata sandinya. Dalam contoh ini kita memiliki form lupa password untuk mendapatkan username atau email untuk mengembalikan password. Setelah formulir dikirimkan, kami mengirim email pemulihan password ke pengguna.

Email pemulihan Password memiliki link ke halaman di mana kita bisa mengatur kata sandinya. Di posting sebelumnya, kita sudah melihat bagaimana cara memasukan password.

Lupa Password Code

Kode HTML ini menampilkan form lupa kata sandi.

<form name="frmForgot" id="frmForgot" method="post" onSubmit="return validate_forgot();">
<h1>Forgot Password?</h1>
	<?php if(!empty($success_message)) { ?>
	<div class="success_message"><?php echo $success_message; ?></div>
	<?php } ?>

	<div id="validation-message">
		<?php if(!empty($error_message)) { ?>
	<?php echo $error_message; ?>
	<?php } ?>
	</div>

	<div class="field-group">
		<div><label for="username">Username</label></div>
		<div><input type="text" name="user-login-name" id="user-login-name" class="input-field"> Or</div>
	</div>
	
	<div class="field-group">
		<div><label for="email">Email</label></div>
		<div><input type="text" name="user-email" id="user-email" class="input-field"></div>
	</div>
	
	<div class="field-group">
		<div><input type="submit" name="forgot-password" id="forgot-password" value="Submit" class="form-submit-button"></div>
	</div>	
</form>

Setelah formulir ini diajukan, maka kode PHP mendapatkan rincian pengguna dari database.

<?php
	if(!empty($_POST["forgot-password"])){
		$conn = mysqli_connect("localhost", "root", "", "infokoding");
		
		$condition = "";
		if(!empty($_POST["user-login-name"])) 
			$condition = " member_name = '" . $_POST["user-login-name"] . "'";
		if(!empty($_POST["user-email"])) {
			if(!empty($condition)) {
				$condition = " and ";
			}
			$condition = " member_email = '" . $_POST["user-email"] . "'";
		}
		
		if(!empty($condition)) {
			$condition = " where " . $condition;
		}

		$sql = "Select * from members " . $condition;
		$result = mysqli_query($conn,$sql);
		$user = mysqli_fetch_array($result);
		
		if(!empty($user)) {
			require_once("forgot-password-recovery-mail.php");
		} else {
			$error_message = 'No User Found';
		}
	}
?>

Lupa Password Mail Mengirim skrip

Jika informasi pengguna ditemukan di database, maka naskah penyisipan email pemulihan password akan dieksekusi. Kami menggunakan phpmailer untuk mengirim email. Skrip suratnya adalah,

<?php
if(!class_exists('PHPMailer')) {
    require('phpmailer/class.phpmailer.php');
	require('phpmailer/class.smtp.php');
}

require_once("mail_configuration.php");

$mail = new PHPMailer();

$emailBody = "<div>" . $user["member_name"] . ",<br><br><p>Click this link to recover your password<br><a href='" . PROJECT_HOME . "php-forgot-password-recover-code/reset_password.php?name=" . $user["member_name"] . "'>" . PROJECT_HOME . "php-forgot-password-recover-code/reset_password.php?name=" . $user["member_name"] . "</a><br><br></p>Regards,<br> Admin.</div>";

$mail->IsSMTP();
$mail->SMTPDebug = 0;
$mail->SMTPAuth = TRUE;
$mail->SMTPSecure = "tls";
$mail->Port     = PORT;  
$mail->Username = MAIL_USERNAME;
$mail->Password = MAIL_PASSWORD;
$mail->Host     = MAIL_HOST;
$mail->Mailer   = MAILER;

$mail->SetFrom(SERDER_EMAIL, SENDER_NAME);
$mail->AddReplyTo(SERDER_EMAIL, SENDER_NAME);
$mail->ReturnPath=SERDER_EMAIL;	
$mail->AddAddress($user["member_email"]);
$mail->Subject = "Forgot Password Recovery";		
$mail->MsgHTML($emailBody);
$mail->IsHTML(true);

if(!$mail->Send()) {
	$error_message = 'Problem in Sending Password Recovery Email';
} else {
	$success_message = 'Please check your email to reset password!';
}

?>
