Php 将数组传递给模型？

只是为了澄清所有的答案，这里的工作完美无瑕！我选择了埃德温，因为他是第一个发帖的

$this -> load -> model('staff_model');
            $this -> load -> library('encrypt');

            $arrData = array(
                'anum' => $this -> encrypt -> encode($this->input->post('anum')),
                'first' => $this -> input -> post('fname'),
                'last' => $this -> input -> post('lname'),
                'why' => $this -> input -> post('why'),
                'aidyear' => $this -> input -> post('aidyear'),
                'signintime' => NULL,
                'comments' => $this -> input -> post('comments'),
                );

            if ($insert = $this -> staff_model -> session($arrData)) {
                redirect('staff_controller/signin_info');
            } else {
                $this -> studentlogin();
            }

型号：

function session($arrData) {
    $null = NULL;
    $sql2 = "INSERT INTO session (anum, first, last, why, aidyear, signintime, studentcomments) 
             VALUES (?, ?, ?, ?, ?, ?, ?)";
    $insert = $this -> db -> query($sql2, $arrData);

    return $insert;

}

不能像这样定义数组变量。试着换成

$data = array (
                    'encrypted' => $this->encrypt->encode('anum'),
                    'first' => $this->input->post('first'),
                    'last'  => $this->input->post('last'),
                    'aidyear' => $this->input->post('aidyear'),
                    'why' => $this->input->post('why'),
                    'comments' => $this->input->post('comments'),
       );

控制器

$this -> load -> model('staff_model');
$this -> load -> library('encrypt');
$this->load->library('form_validation');
$this->load->helper('url');

//validate form input
        $this->form_validation->set_rules('anum', 'Anum', 'required');

        other validation rules
                .....

        if ($this->form_validation->run() == FALSE)
        {
                  redirect('back to previous page through controller');
        }else{


    $data = array (
                    'encrypted' => $this->encrypt->encode('anum'),
                    'first' => $this->input->post('first'),
                    'last'  => $this->input->post('last'),
                    'aidyear' => $this->input->post('aidyear'),
                    'why' => $this->input->post('why'),
                    'comments' => $this->input->post('comments'),
       );

     if ($insert = $this -> staff_model -> session($data)) {
         print_r($insert);
    }
}

在控制器中使用此选项：

$arrData = array();

//在数组文件中使用与数据库表中相同的名称，如下所示

    $arrData['anum'] = $this->encrypt->encode('anum');
    $arrData['first'] = $this->input->post('first');
    $arrData['last'] = $this->input->post('last');
    $arrData['aidyear'] = $this->input->post('aidyear');
    $arrData['why'] = $this->input->post('why');
    $arrData['studentcomments'] = $this->input->post('comments');

  if ($this -> staff_model -> session($arrData)) {
                redirect('staff_controller/signin_info');
  }

而在模型中只是使用

//不需要写变量名，因为我们已经在数组中使用了相同的字段名

function session($arrData)
     {
       if($this->db->insert($arrData))
          return true;
        else
          return false;
      }

当然，您可以将数组传递给您的模型。但是你需要发布你的错误并展示你所尝试的。编辑了原始的帖子当然你可以将数组传递给你的模型。但是你需要发布你的错误并展示你所做的尝试。编辑了原始的帖子仍然会得到这样的信息：未定义变量：曾经发生过的变量错误插入会话anum，first，last，why，aidyear，signetime，studentcomments值NULL，NULL，NULL，NULL，NULL，NULL似乎没有传递任何内容，因为所有值都是空的NULL@RaGe10940不能使用$encrypted、$first等。。直接地因为它在数组中。更改$data['encrypted']、$data['first']等。仍然会收到消息：未定义变量：变量错误插入会话anum、first、last、why、aidyear、signintime、studentcomments值NULL、NULL、NULL、NULL、NULL似乎什么都没有传递，因为所有的值都是NULL@RaGe10940您不能使用$encrypted，美元优先等等。。直接地因为它在数组中。更改$data['encrypted']、$data['first']等。。
