我的网站上有一个注册/登录系统,现在它在页面顶部显示错误和成功文本。我希望它在表单下显示它。但每当我尝试将其添加到表单下方时,它就无效了!
session_start();
include_once('class.register.php');
$register = new Register();
if(isset($_POST['register']))
{
if($register->process())
echo "Successfully Signed Up!";
else
$register->show_errors();
}
$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));
这样可行,但它会在页面顶部输出文字。
我尝试将此代码放在'form'结束标记下面:
<?php
if(isset($_POST['register']))
{
if($register->process())
echo "Successfully Signed Up!";
else
$register->show_errors();
}
?>
但是当我在表单下移动时,它会显示“无效提交”,这是由此引起的:
public function valid_token()
{
if(!isset($_SESSION['token']) || $this->token != $_SESSION['token'])
$this->errors[] = 'Invalid Submission';
return count($this->errors)? 0 : 1;
}
这是我谈论的形式
<form role="form" method="POST" action="<?php echo $_SERVER['PHP_SELF'];?>">
<div class="form-group">
<div class="row">
<div class="col-sm-6">
<label for="firstname">Firstname</label>
<input type="text" class="form-control" id="firstname" name="firstname" placeholder="Firstname">
</div>
<div class="col-sm-6">
<label for="surname">Surname</label>
<input type="text" class="form-control" id="surname" name="surname" placeholder="Surname">
</div>
</div>
</div>
<div class="form-group">
<label for="username">Username</label>
<input type="text" class="form-control" id="ruser" name="ruser" placeholder="Username">

<div class="form-group">

<input type="email" class="form-control" id="remail" name="remail" placeholder="Enter email">

<div class="form-group">

<div class="col-sm-6">

<input type="password" class="form-control" id="rpass" name="rpass" placeholder="Password">

<div class="col-sm-6">
<label for="password2">Repeat password</label>
<input type="password" class="form-control" id="rpass2" name="rpass2" placeholder="Password">
</div>
</div>
</div>
<div class="checkbox">
<label>
<input type="checkbox"> I agree to the <a href="#">Terms of Service</a> and <a href="#">Privacy Policy</a>
</label>
</div>
<input type="hidden" name="token" value="<?php echo $token;?>"/>
<button type="submit" name="register" class="btn btn-block btn-color btn-xxl">Create an account</button>
</form>
答案 0 :(得分:1)
因此,由于valid_token()函数中的if测试失败,令牌不再在会话中(确保session_start();
仍在代码的顶部),或者更可能{{1是罪魁祸首。
我有一种预感,也许你现在正在按顺序执行这行代码:
$this->token != $_SESSION['token']
如果此行在您调用$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));
之前运行,那么会在您尝试匹配之前更改会话中的令牌,从而导致valid_token()函数出现问题。
如果不是这种情况,我会准确调查$register->process()
设置的时间和地点,以确保在$this->token
发生之前正确填充。
