php - CodeIgniter 表单验证不起作用

Question

似乎无法在代码点火器上进行表单验证，不确定出了什么问题！

这是我的控制器类：

class registerController extends MY_Controller {

    // --- Methods -----------------

    function __construct()
    {
        parent::__construct();

        $this->firephp->log('REGISTER PAGE CONTROLLER ACTIVE');

        //Load user model
        $this->load->model('usersModel');

        //load form validation
        $this->load->helper('form');
        $this->load->library('form_validation');

    }

    //------------------------------

    public function register()
    {

        $this->form_validation->set_rules('registerForenameFieldName', 'Fist Name', 'required');

        //This is executed when the form is submitted
        if ($this->form_validation->run() == FALSE)
        {

            $this->firephp->log('Registration form validation failed');

            //Load in the views
            $this->load->view('global/head.php');
            $this->load->view('global/top.php');
            $this->load->view('register/register.php');
            $this->load->view('global/footer.php');

        } else {

            $this->firephp->log('Registration form validation succeeded');

            //Model method here

            //Load in the views
            $this->load->view('global/head.php');
            $this->load->view('global/top.php');
            $this->load->view('home.php');
            $this->load->view('global/footer.php');
        }

    }

}

和我的表格：

<?php  echo form_open('register'); ?>

    <div id="registerErrors"><?php echo validation_errors(); ?></div>

        <table id="registerTable">

            <tr>
            <td class="regLeftCell"><p>First Name</p></td>
            <td class="regRightCell">
            <input id="registerForenameField" class="textField registerField" name="registerForenameFieldName" type="text" placeholder="Forename" value="<?php echo set_value('registerForenameFieldName'); ?>"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Last Name</p></td>
            <td class="regRightCell">
            <input id="registerSurnameField" class="textField registerField" name="registerSurnameFieldName" type="text" placeholder="Surname" value="<?php echo set_value('registerSurnameFieldName'); ?>"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Email Address</p></td>
            <td class="regRightCell">
            <input id="registerEmailField" class="textField registerField" name="registerEmailFieldName" type="text" placeholder="Email Address"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Choose Password</p></td>
            <td class="regRightCell">
            <input id="registerPasswordField" class="textField registerField" name="registerPasswordFieldName" type="text" placeholder="Password"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Confirm Password</p></td>
            <td class="regRightCell">
            <input id="registerConfirmPasswordField" class="textField registerField" name="registerConfirmPasswordFieldName" type="text" placeholder="Confirm Password"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Address Line 1</p></td>
            <td class="regRightCell">
            <input id="registerAddress1Field" class="textField registerField" name="registerAddress1FieldName" type="text" placeholder="Address Line 1"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Address Line 2</p></td>
            <td class="regRightCell">
            <input id="registerAddress2Field" class="textField registerField" name="registerAddress2FieldName" type="text" placeholder="Address Line 2"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Address Line 3</p></td>
            <td class="regRightCell">
            <input id="registerAddress3Field" class="textField registerField" name="registerAddress3FieldName" type="text" placeholder="Address Line 3"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Post Code</p></td>
            <td class="regRightCell">
            <input id="registerAddressPostCodeField" class="textField registerField" name="registerPostCodeFieldName" type="text" placeholder="Post Code"></input>
            </td>
            </tr>

            <tr>
            <td class="regLeftCell"><p>Country</p></td>
            <td class="regRightCell">
            <input id="registerAddressCountryField" class="textField registerField" name="registerSurnameFieldName" type="text" placeholder="Country"></input>
            </td>
            </tr>

        </table>

        <div id="registerButton">
            <input class="button registerSubmitButton" type="submit" value="Register"/>
        </div>


    </form>

路由设置如下：

$route['register'] = 'registerController/register';

怎么了？它只是每次都失败而不会显示错误。

它只是重新加载同一页面而没有验证错误。$this->form_validation->run() 每次都评估为 FALSE，因为我已经将它记录在 FirePHP 中，这是一个 Firebug 扩展。

编辑：

值得一提的是，尽管它加载了页面，但我在控制台中收到了 404 错误：

我终于找到了答案！我的服务器配置不正确，我没有启用 mod_rewrite，所以没有一个请求正常工作。

Ubuntu 用户，在命令行上关闭它以启用它：sudo a2enmod rewrite

然后重新启动 Apache。

我正在使用以下.htaccess：

<IfModule mod_rewrite.c>

    RewriteEngine On
    RewriteBase /

    #Removes access to the system folder by users.
    #Additionally this will allow you to create a System.php controller,
    #previously this would not have been possible.
    #'system' can be replaced if you have renamed your system folder.
    RewriteCond %{REQUEST_URI} ^system.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #When your application folder isn't in the system folder
    #This snippet prevents user access to the application folder
    #Rename 'application' to your applications folder name.
    RewriteCond %{REQUEST_URI} ^application.*
    RewriteRule ^(.*)$ /index.php?/$1 [L]

    #Checks to see if the user is attempting to access a valid file,
    #such as an image or css document, if this isn't true it sends the
    #request to index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule ^(.*)$ /index.php?/$1 [L]

</IfModule>

<IfModule !mod_rewrite.c>
    # If we don't have mod_rewrite installed, all 404's
    # can be sent to index.php, and everything works as normal.
    ErrorDocument 404 /index.php
</IfModule>

您没有在form_open函数中给出控制器名称，应该是

<?php  echo form_open('registerController/register'); ?>

这是什么意思 - “每次都失败” - 显示空白页面？还是错误？要不然是啥？

构造函数在执行吗？

function __construct()
{
    parent::__construct();
    var_dump('contructor');
}

是否调用了注册函数？

function register()
{
    var_dump('register function');
}

或者只是添加

$this->firephp->log('Registration function');

在register函数的开头，让我们知道你的调试结果。

您是否尝试过这里的示例：

将此行添加到您的 __construct：

$this->load->helper('url');

然后试试这个：

echo form_open(site_url("register"));

功能 site_url 可以帮助您使用路由 url。如果这没有任何帮助，您可以尝试 echo base_url(); 和其他 url 辅助函数来完成 url。

我不明白为什么人们要在 firebug 中加载用于打印变量和数组的扩展。对于我使用这个的大多数项目：是一样的。你不需要firephp核心。而且你不需要firebug的firephp插件。

<?php
$debug[] = 'Hello World';
// and/or
$debug[] = array('a1'=>"ArrValue1",'a2'=>"ArrValue2");
?>

<!-- add before </body>... -->
<?php if(isset($debug)): ?>
<script type="text/javascript">
jQuery(document).ready(function(){ 
    <?php foreach($debug as $js): if(is_array($js)) $js= json_encode($js); else $js = '"'.$js.'"'; ?>
    console.log(<?php echo $js; ?>);
    <?php endforeach; ?>
})
</script>
<?php endif; ?>
