Question

我目前在这里遇到问题。我有我的html登录页面，一旦我点击登录，它将跳转到php并运行php并从xml中获取数据。但是，当我点击登录时。它只会跳转到PHP而不采取任何行动。

有谁知道代码缺少什么？

Html页面：

    <!DOCTYPE html>
    <html>
    <head> 
    </head> 
    <body>

    <fieldset>
      <form method="post" action="login.php">
            <p>Email* : <input type="email" name="email" id="email"/></p>
            <p>Password* : <input type="password" name="password" id="password"/> 
   </p> 
        <div class="buttoninput">
                <input type="submit" name="login "value="Login" />
                <input type="reset" value="Reset" />    
        </div>
      </form>
    </fieldset>
    </body>
    </html>

Php页面：

<?php
session_start();
if(isset($_POST['login'])) {

    $email = $_POST['email'];
    $pass = $_POST['password'];
    $customerxml = simplexml_load_file('customer.xml');

    $email_add = "";
    $passw = "";
    $customerID = "";

    for($i = 0; $i < count($customerxml); $i++){

        $email_add = $customerxml->info[$i]->Email;
        $passw = $customerxml->info[$i]->Password;
        $customerID = $customerxml->info[$i]->CustomerID;

        if(($email != $email_add) || ($passw != $pass)){
            $message = "wrong email/password";
    echo "<script type='text/javascript'>alert('$message');</script>";
        }


        if(($email == $email_add) && ($passw == $pass)){

            $_SESSION['logged_in'] = true;

            unset($mydata->info[$i]->Password);


            $_SESSION['customer-info'] = json_encode($customerxml->info[$i]);


            exit(header("Location: ./bidding.php"));
        }
    }

}
?>

Answer 1

 <input type="submit" name="login "value="Login" />

name="login "中有空格删除该空格。因为空格if(isset($_POST['login'])) {这是失败的

Answer 2

替换此行

if(isset($_POST['login'])) {

通过

if(isset($_POST['email']) && isset($_POST['password'])) {

在login.php文件中

或删除

中的空格

<input type="submit" name="login "value="Login" />

（name="login "）

Html无法从xml文件中获取或输入数据
