Question

我有一个表单没有输出任何错误消息我错过了什么？

型号：

function createUser($username = NULL ,$passwordHash = NULL ,$firstname = NULL ,$lastname = NULL ,$email = NULL,$group = NULL ,$active = NULL)
    {
        $data = array('userName' => $username, 'userFirstName' => $firstname, 'userLastName' => $lastname, 'userEmail' => $email, 'userPassword' => sha1($passwordHash), 'userGroup' => $group, 'userActive' => $active);

        $this->db->insert('users',$data);

        return TRUE;
    }

查看：

<h1><?php echo $companyName; echo nbs(1);?> - <?php echo $pageTitle; ?></h1>

<?php
if($success == TRUE) {
echo '<section id = "validation">Page Updated</section>';   
}
?>

您需要将<input> s 放在<{1}}标记之外！这是主要问题。

此外：

没有名为“submit”的输入：您的提交按钮实际上没有名称属性。而且，顺便说一下，因为你已经在使用form_validation类，所以检查（<label> </label>）是多余的;
我看到的另一个多余的事情是将TRUE（即，将其xss_cleaned）传递给input-＆gt; post方法：你已经有了大量的xss_clean验证规则，所以为什么要再次传递在验证检查期间已经通过它的昂贵的额外处理？
旁注，如果您使用Active Record或查询绑定，则不必转义变量，因此我也会删除该部分：）
我相信你对if input->post('submit')的调用将会失败：函数，就像“callback_”验证规则所关注的那样，是“username_check”;除了双下划线通常用于PHP中的“魔术方法”;您可以安全地删除这两者，或者如果您真的想要在函数名称上加下划线（只有一个），您可能需要调用“__username_check()”。
你加载相同的视图三次，为什么？我相信你可以像这样重写整个索引方法：
```
callback__check_username
```

<强>更新

至于用户名检查，因为CodeIgniter的v.2.0，你在验证规则中具有这种能力：如果放置is_unique规则，事实上，它会自动查询数据库以检查它。语法是：

function index()
{
  $this->form_validation->set_rules('userName', 'User Name', 'trim|required|xss_clean|callback_username_check');
    $this->form_validation->set_rules('userPassword', 'User Password', 'trim|required|xss_clean|sha1');
    $this->form_validation->set_rules('userFirstName', 'First Name', 'trim|required|xss_clean');
    $this->form_validation->set_rules('userLastName', 'Last Name', 'trim|required|xss_clean');
    $this->form_validation->set_rules('userEmail', 'E-Mail', 'trim|required|xss_clean');
    $this->form_validation->set_rules('userGroup', 'User Group', 'trim|required|xss_clean');
    $this->form_validation->set_rules('userActive', 'User Active', 'trim|required|xss_clean');

    if ($this->form_validation->run() == FALSE) {

        $data['success'] ="";

    }else{

        $username = $this->input->post('userName');
        $password = $this->input->post('userPassword');
        $firstname = $this->input->post('userFirstName');
        $lastname = $this->input->post('userLastName');
        $email = $this->input->post('userEmail');
        $group = $this->input->post('userGroup');
        $active = $this->input->post('userActive');
        $passwordHash = $this->encrypt->sha1($password);

        if ($this->core_model->createUser($username,$passwordHash,$firstname,$lastname,$email,$group,$active)) 
        {
            $data['success'] = TRUE;

        }      
    }
    $data['companyName'] = $this->core_model->companyName();
    $data['pageTitle'] = "Create User";
    $this->load->view('admin/assets/header', $data);
    $this->load->view('admin/createUser', $data);
    $this->load->view('admin/assets/footer');
}

在你的情况下，可能是

is_unique[table.field]

不输出表单错误消息
