Question

我是新来的，所以如果我没有提出正确的问题，或者提供过多的信息（或更少），我会事先道歉。

我有这个问题在php中创建我的登录页面：在很多行中，它给了我语法错误。

这些行是：31,39,42,43,55,56,57,62,63,65,68,71,73,77,79,80,85,93,94,95,96,97 ，101,103,111,112,113,114,115,119。

很抱歉，如果我犯了这么多错误，我会在网上学习和搜索教程，但是他们没有帮助我。

这是我的整个代码：

<?php
$servername = "localhost";
$email="root";
$password="";
$dbname="testnew";
//create connection
$conn = new MySQLi($servername, $email, $password, $dbname);
//check the connection
if($con->connect_error){
    die("connection failed".$conn->connect_error);  
}
if(isset($_POST['email'])){
    $email = $_POST['email'];
    $pass = $_POST['pass'];
    $sql = "SELECT * FROM loginnnew WHERE email='".$email."' AND password='".$pass."' LIMIT 1;
    $result = $conn->query(sql);
    if($result->num_rows>0){
    echo 'Has iniciado sesión correctamente'
    exit();
    }else{
    echo 'Contraseña o e-mail incorrectos.';
    exit();
    }
    }
}
?>

希望有人可以提供帮助。提前谢谢！

Answer 1

我无法看到你的SQL连接是什么样的，但我确实看到你忘了为$ sql变量结束String。试试这个。

另外，下次清理代码。有拼写错误，缺少分号和各种东西。

＆＃13;

<?php
$servername = "localhost";
$email="root";
$password="";
$dbname="testnew";
//create connection
$conn = new mysqli($servername, $email, $password, $dbname);
//check the connection
if($conn->connect_error){
	die("connection failed(".$conn->connect_error.")");	
}
if(isset($_POST['email'])){
	$email = $_POST['email'];
	$pass = $_POST['pass'];
	$sql = "SELECT * FROM loginnnew WHERE email='".$email."' AND password='".$pass."' LIMIT 1";
	$result = $conn->query(sql);
	if($result->num_rows>0){
	echo 'Has iniciado sesión correctamente';
	exit();
	}else{
	echo 'Contraseña o e-mail incorrectos.';
	exit();
	}
	}
}
