当我使用代码插入数据时，我收到一条消息，表明您注册成功，即数据已插入表中，但我无法在本地数据库中找到数据。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Registration</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<?php
require('db.php');
if (isset($_REQUEST['username'])) {
$username = "username";
$email = "email";
$password = "password";
$trn_date = date("Y-m-d H:i:s");
$query = "INSERT into `users` (username, password, email, trn_date)
VALUES ('$username', '".md5($password)."', '$email', '$trn_date')";
$result = mysqli_query($con, $query);
if($result) {
echo "<div class='form'>
<h3>You are registered successfully.</h3>
<br/>Click here to <a href='login.php'>Login</a></div>";
}
} else {
?>
<div class="form">
<h1>Registration</h1>
<form name="registration" action="" method="post">
<input type="text" name="username" placeholder="Username" required />
<input type="email" name="email" placeholder="Email" required />
<input type="password" name="password" placeholder="Password" required />
<input type="submit" name="submit" value="Register" />
</form>
</div>
<?php }
?>
</body>
</html>
最佳答案
你必须先了解更多有关 php 的知识，然后才能提问。
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Registration</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<body>
<?php
require('db.php');
if (isset($_POST['username'])){
$username= $_POST["username"];
$email = $_POST["email"];
$password = $_POST["password"];
$trn_date = date("Y-m-d H:i:s");
$query = "INSERT into `users` (username, password, email, trn_date)
VALUES ('$username', '".md5($password)."', '$email', '$trn_date')";
$result = mysqli_query($con,$query);
if($result){
echo "<div class='form'>
<h3>You are registered successfully.</h3>
<br/>Click here to <a href='login.php'>Login</a></div>";
}
}else{
?>
<div class="form">
<h1>Registration</h1>
<form name="registration" action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="text" name="username" placeholder="Username" required />
<input type="email" name="email" placeholder="Email" required />
<input type="password" name="password" placeholder="Password" required />
<input type="submit" name="submit" value="Register" />
</form>
</div>
<?php } ?>
</body>
</html>
关于php - 注册成功但数据库中没有数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40361656/
