如何在codeigniter中创建用户时创建空行

Question

我正在使用 PHP Codeigniter。在这张表中，我有一个 Retailer 表，其中我有一个字段 No of Users 需要零售商。当管理员创建零售商时，他在字段 no of users 中插入的值是否有可能必须在另一个表 User 中创建那么多行。我只想在用户表中创建那么多空行，这些行映射到零售商 ID。用户表中的用户有一个字段 Key 必须是零售商的唯一键。我是codeigniter的新手，没有任何逻辑如何做到这一点。 以下是我创建零售商的代码： 控制器代码：

<?php

类 Reseller 扩展 Admin_Controller {

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

public function index ()
{
    // Fetch all users
    $this->data['users'] = $this->reseller_m->get();

    // Load view
    $this->data['subview'] = 'admin/reseller/index';
    $this->load->view('admin/_layout_main', $this->data);
}
    public function reseller ()
{
    // Fetch all users
    $this->data['users'] = $this->reseller_m->get();

    // Load view
    $this->data['subview'] = 'admin/reseller/users'; //Users variable stores the suvbview 
    $this->load->view('admin/_layout_main', $this->data);
}


public function edit ($id = NULL)
{
    // Fetch a user or set a new one
    if ($id) {
        $this->data['user'] = $this->reseller_m->get($id);
        count($this->data['user']) || $this->data['errors'][] = 'User could not be found';
    }
    else {
        $this->data['user'] = $this->reseller_m->get_new();
    }

    // Set up the form
    $rules = $this->reseller_m->rules_admin;
    $id || $rules['password']['rules'] .= '|required';
    $this->form_validation->set_rules($rules);

    // Process the form
    if ($this->form_validation->run() == TRUE) {

$data = $this->reseller_m->array_from_post(array('sip_username','sip_password','key','allocation_block','name','email','password','phone',' balance','user_num','address','country','created','modified','status'));

        $data['password'] = $this->reseller_m->hash($data['password']);


        $key=$this->reseller_m->save($data, $id);
        for($i=1; $i<=$data['user_num'];$i++)
            {
            $userdata=array('key'=>$key);
        // here users is taken name of user table with retailer_id is field
            $this->db->insert('users',$userdata);
             }



        redirect('admin/reseller');
    }

    // Load the view
    $this->data['subview'] = 'admin/reseller/edit';
    $this->load->view('admin/_layout_main', $this->data);
}


public function delete ($id)
{
    $this->reseller_m->delete($id);
    redirect('admin/reseller');

Answer 1

修改如下函数。

  public function edit ($id = NULL)
 {
// Fetch a user or set a new one
if ($id) {
    $this->data['user'] = $this->reseller_m->get($id);
    count($this->data['user']) || $this->data['errors'][] = 'User could not be found';
}
else {
    $this->data['user'] = $this->reseller_m->get_new();
}

// Set up the form
$rules = $this->reseller_m->rules_admin;
$id || $rules['password']['rules'] .= '|required';
$this->form_validation->set_rules($rules);

// Process the form
if ($this->form_validation->run() == TRUE) {
    $data = $this->reseller_m->array_from_post(array('sip_username','sip_password','key','allocation_block','name','email', 'password','phone','user_num','address','status','country','created','modified','balance'));
    $data['password'] = $this->reseller_m->hash($data['password']);
    //modify here
    $retailer_id=$this->reseller_m->save($data, $id); 
    for($i=1; $i<=$data['user_num'],$i++)
    {
        $userdata=array('retailer_id'=>$retailer_id);
        // here users is taken name of user table with retailer_id is field
        $this->db->insert('users',$userdata);
    }

    redirect('admin/reseller');
 }

  // Load the view
  $this->data['subview'] = 'admin/reseller/edit';
  $this->load->view('admin/_layout_main', $this->data);
 }
