Php 表单验证后重定向codeigniter多个表单？

在表单验证后，我遇到重定向问题。我在不同的视图中有3个不同的表单，经过验证后，如果表单未能提交，我想将其重定向到上一个登录页面。它工作正常，但在提交表单后，如果我单击url并按enter键。当我在主页中时，它会重定向到联系人。我希望它重定向到他提交的上一个登录页面。我认为这不是正确的做法，提前谢谢

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

我不明白为什么你有三个相同的表格，但好吧。。。为什么不呢？这可能是一种继续的方式（使用相同的验证方法以避免重复代码）

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

有不同的方法进行：

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

1） 对当前位置使用隐藏输入：

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

myform1.php

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<input type="hidden" name="redirect_to" value="<?php echo current_url(); ?>" />
<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

但它并不完美，因为使用

redirect（）

方法无法轻松地重新填充表单

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

2） 这就是为什么我们通常不使用

验证表单（）

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

您希望发布表单，对其进行验证，然后在验证失败时再次显示带有验证错误的表单，或者在验证通过时调用register方法

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

最好的方法是将表单发回自己。这样，在您的方法中，您可以检查表单是否已提交，并确定要执行的操作：

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

public function myform1()
{
    $this->load->library('form_validation');

    $this->form_validation->set_rules('username', 'Username', 'required');
    $this->form_validation->set_rules('password', 'Password', 'required');

    if ($this->form_validation->run() == FALSE)
    {
        $this->load->view('myform');
    }
    else
    {
        $this->register();
    }
}

观点：

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

<html>
<head>
<title>My Form 1</title>
</head>
<body>

<?php echo validation_errors(); ?>

<?php echo form_open('con/myform1'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email"  value="" size="50" />

<div><input type="submit" name-'submit' /></div>

</form>

</body>
</html>

我要做的是为不同类型的表单错误创建一个错误文件夹。。。。。
对于表单验证错误，我将其重定向到特定的错误页面。。。
这对我来说很好

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

我还觉得您可能试图对多个表单视图使用同一个控制器。。。
这就产生了一个问题

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

我认为您的联系人和登录表单都有相同的重定向控制器con/myform1。。。。
看看

<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>

</form>

</body>
</html>

希望这有帮助……
“我也觉得您可能试图对多个表单视图使用同一个控制器……这会产生问题……”是的，完全正确。这不是一个好的解决办法。
<?php echo validation_errors(); ?>

<?php echo form_open('con/validate_form'); ?>

<h5>Username</h5>
<input type="text" name="username" value="" size="50" />

<h5>Password</h5>
<input type="text" name="password" value="" size="50" />

<h5>Password Confirm</h5>
<input type="text" name="passconf" value="" size="50" />

<h5>Email Address</h5>
<input type="text" name="email" value="" size="50" />

<div><input type="submit" name='submit1' value="Submit1" /></div>
