Question

我有一个创建新帐户页面。表单位于名为Register.php的页面中，一旦用户提交，它将转到Confirm.php，如果一切正确，它将验证字段，显示“帐户创建”消息。

在Chrome中。错误消息显示在Register.php中，一次全部显示填充字段然后只显示confirm.php。但在Mozilla中，它转到Confirm.php并显示一个空白页面。

我的Register.php代码是：

<div class="signup_form">
<form action="confirm.php" method="post" >

<?php 
    session_start();
    if(isset($_SESSION['error']))
    {
        echo '<p>'.$_SESSION['error']['username'].'</p>';
        echo '<p>'.$_SESSION['error']['email'].'</p>';
        echo '<p>'.$_SESSION['error']['password'].'</p>';
        unset($_SESSION['error']);
    }
?>


<p>
<font size="3" face="arial" color="gray"> <label for="username"><b> UserName*</b> </label> </font>
<input name="username" type="text" id="username" input style="height:33px" size = "50" size="30"/>

</p>
<p>
<font size="3" face="arial" color="gray"> <label for="email"><b> E-mail Address*</b> </label> </font>
<input name="email" type="text" id="email"  input style="height:33px" size = "50" size="30"/>
</p>


<p>
<font size="3" face="arial" color="gray"> <label for="password"><b> Password*</b> </label> </font>
<input name="password" type="password" id="password"   input style="height:33px" size = "50" size="30"/>
    </p>  
<p>
<input name="submit" type="image" src="images/submit.gif" value="submit"/>    </p>
</form>

</div>

并且对于Confirm.php代码是：

<?php
    session_start();
    include('configdb.php');

    if(isset($_POST['submit']))
    {
        if($_POST['username'] == '')
        {

            $_SESSION['error']['username'] = "User Name is required.";
        }
        if($_POST['email'] == '')
        {
            $_SESSION['error']['email'] = "E-mail is required.";
        }
            else
            {
                if(preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9\._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9\._-]+)+$/", $_POST['email']))
                {
                    $email= $_POST['email'];
                    $sql1 = "SELECT * FROM user WHERE email = '$email'";
                    $result1 = mysqli_query($mysqli,$sql1) or die(mysqli_error($mysqli));
                    if (mysqli_num_rows($result1) > 0) {
                        $_SESSION['error']['email'] = "This Email is already used.";
                    }
                }
                else
                {
                $_SESSION['error']['email'] = "Your email is not valid.";
                }
            }
        if($_POST['password'] == '')
        {
            $_SESSION['error']['password'] = "Password is required.";
        }

        if(isset($_SESSION['error']))
        {
            header("Location: register.php");
            exit;
        }
        else
        {
            $username = $_POST['username'];
            $email = $_POST['email'];
            $password = $_POST['password'];

            $sql2 = "INSERT INTO users (username, email, password) VALUES ('$username', '$email', '$password')";
            $result2 = mysqli_query($mysqli,$sql2) or die(mysqli_error());

            if($result2)
            {

            echo '<div>Your account is now active. You may now <a href="login.php">Log in</a></div>';   
        }
    }
} ?>

将if(isset($_POST['submit']))与input type="image"结合使用无法正常工作，因为浏览器应发送submit.x和submit.y以及点击图片的坐标。

相反，请尝试使用if($_POST)确保表单已提交，或者isset($_POST['username'])或其他您知道名称的字段。

php代码在Chrome和Mozilla浏览器中表现不同
