控制器/表单在执行内容时做奇怪的事情 [英] controller/form doing strange things when content is implemented

问题描述

我有下面的控制器，我想它做以下事情：

I have the controller below and I would like it do the following things:

• 如果用户名是

• Show an error if the username is taken -> currently just submits as normal even through the specific user is in the database.

如果存在错误，填充数据 - >

Populate with data if there was an error -> currently populates with the imported data if correct

查看：

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



<?php
if($success == TRUE) {
echo '<section id = "validation">Page Updated</section>';   
}
?>
    <p>Error: <?php echo validation_errors();?></p>
    <div class="formContent">
        <form action="createUser" method="post">
            <fieldset class="control-group">
                <label for="userName">User Name:</label><input type="text" id="userName" name="userName"  value="<?php echo set_value('userName'); ?>" placeholder="User Name">
                <label for="userPassword">User Password:</label><input type="password" id="userPassword" name="userPassword" value="<?php echo set_value('userPassword'); ?>" placeholder="User Password">
                <label for="userFirstName">First Name:</label><input type="text" id="userFirstName" name="userFirstName" value="<?php echo set_value('userFirstName'); ?>" placeholder="First Name">
                <label for="userLastName">Last Name:</label><input type="text" id="userLastName" name="userLastName" placeholder="Last Name">
                <label for="userEmail">E-Mail:</label> <input type="text" id="userEmail" name="userEmail"  placeholder="Admin E-mail">
                <label for="userGroup"> User Group:</label>
                    <select name="userGroup" id="userGroup">
                        <option value="select">Please Select</option>
                        <option value="admin">Admin</option>
                        <option value="user">User</option>
                    </select>
                <label for="userActive"> User Active:</label>
                        <select name="userActive" id="userActive">
                            <option value="select">Please Select</option>
                            <option value="yes">Yes</option>
                            <option value="no">No</option>
                        </select>
                <div>
                    <button type="submit" class="btn-primary">Create</button>
                </div>
                </fieldset>
        </form>
    </div>

控制器：

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class createUser extends CI_Controller {


    public function index()
    {
        //Form Validation prep making sure its all clean

        $this->form_validation->set_rules('userName', 'User Name', 'trim|required|is_unique[users.userName]|xss_clean');
        $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 form validation fails load previous page with errors else do the job and insert data into db

        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); // Lets encrypt the password why sha1?  MD5 is for tossers

            // If the data is correct follow through with db insert

            if($this->users_model->createUser($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');
    }
}

推荐答案

如果我是你， a href =http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks =nofollow> http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks ）

If I were you, I would use a callback ( http://codeigniter.com/user_guide/libraries/form_validation.html#callbacks )

        $this->form_validation->set_rules('userName', 'User Name', 'trim|required|xss_clean|callback__checkUsername');

，使用set_value（）函数

as for your select drop downs, use the set_value() function

                <select name="userGroup" id="userGroup">
                    <option value="select"<?=(set_value('userGroup')=='select')?' selected="selected"':''?>>Please Select</option>
                    <option value="admin"<?=(set_value('userGroup')=='admin')?' selected="selected"':''?>>Admin</option>
                    <option value="user"<?=(set_value('userGroup')=='user')?' selected="selected"':''?>>User</option>
                </select>
