Codeigniter:将URI与表单一起使用

我正在使用URI来指导库中的函数... 查看文件(这是巨大的,所以我只是发布开头行):

<?php print form_open('survey',array('class'=>'horizontal','id'=>'form_survey'))?>

库:

function survey_form($container)
{
    $id = $this->CI->session->userdata('id');
    // Setup fields
    for($i=1;$i<18;$i++){
      $fields["a_".$i] = 'Question '.$i;
    }
    for($i=1;$i<24;$i++){
      $fields["b_".$i] = 'Question '.$i;
    }
    $fields["firstname"] = "First Name";
    $fields["lastname"] = "Last Name";
    $fields["phone"] = "Phone";
    $fields["company_name"] = "Company Name";
    $fields['company_address'] = "company_address";
    $fields['company_phone'] = "company_phone";
    $fields['company_state'] = "company_state";
    $fields['company_city'] = "company_city";
    $fields['company_zip'] = "company_zip";
    $fields['job_title'] = "job_title";
    $fields['job_type'] = "job_type";
    $fields['job_time'] = "job_time";
    $fields['department'] = "department";
    $fields['supervisor'] = "supervisor";
    $fields['vision'] = "vision";
    $fields['height'] = "height";
    $fields['weight'] = "weight";
    $fields['hand_dominance'] = "hand_dominance";
    $fields['areas_of_fatigue'] = "areas_of_fatigue";
    $fields['job_description'] = "job_description";
    $fields['injury_review'] = "injury_review";
    $fields['job_positive'] = "job_positive";
    $fields['risk_factors'] = "risk_factors";
    $fields['job_improvement_short'] = "job_improvement_short";
    $fields['job_improvement_long'] = "job_improvement_long";
    $fields["c_1"] = "Near Lift";
    $fields["c_2"] = "Middle Lift";
    $fields["c_3"] = "Far Lift";
    $this->CI->validation->set_fields($fields);

    // Set Rules

    for($i=1;$i<18;$i++){
      $rules["a_".$i]= 'hour|integer|max_length[2]';
    }
    for($i=1;$i<24;$i++){
      $rules["b_".$i]= 'hour|integer|max_length[2]';
    }
    // Setup form default values
    $this->CI->validation->set_rules($rules);

        if ( $this->CI->validation->run() === FALSE )
        {
            // Output any errors
            $this->CI->validation->output_errors();
        }
        else
        {
            // Submit form
            $this->_submit();
        }
    //Tool for current user
    if ($method == 'update') {
        // Modify form, first load
        $this->CI->db->from('be_user_profiles');
        $this->CI->db->where('user_id' , $id);
        $user = $this->CI->db->get();
        $this->CI->db->from('be_survey');
        $this->CI->db->where('user_id' , $id);
        $survey =   $this->CI->db->get();
        $user = array_merge($user->row_array(),$survey->row_array());
        $this->CI->validation->set_default_value($user);

        // Display page
        $data['user'] = $user;
    }
    $data['header'] = 'Risk Assessment Survey';
    $data['page'] = $this->CI->config->item('backendpro_template_public') . 'form_survey';
    $this->CI->load->view($container,$data);
}

            flashMsg('success','You finished the assessment successfully!');

            $profile['test_complete'] = '1';
            $survey['user_id'] = $id;
            $this->CI->db->trans_begin();

            // Add user_profile details to DB
            $this->CI->db->insert('be_user_profiles',$profile);

    }
}

控制器功能:

function survey()
{
    $id = $this->session->userdata('id');
    $data['member'] = $this->home_model->getUsers(array('user_id'=>$id));

    //Convert the db Object to a row array
    $data['manager'] = $data['member']->row();
    $manager_id = $data['manager']->manager_id;
    $data['manager'] = $this->home_model->getUsers(array('manager_id'=>$id));
    $data['manager'] = $data['manager']->row();
    if ($data['manager']->credits == '0')   {
        flashMsg('warning',"You can't complete the assessment until your manager has purchased credit.");
        redirect('home','location');
    }
    elseif ($data['manager']->test_complete == '3'){
        flashMsg('warning',"You already completed the Assessment.");
        redirect('home','location');                        
    }
    else{
        $data['header'] = "Home";
        $this->survey_form_processing->survey_form($this->_container,$data);
    }
}

提交函数类似,如果$ method ==“update”则更新db,如果方法==“create”则更新。

问题,提交表单时,它没有考虑表单提交到函数“survey”的url b / c,它将数据传递给lib函数,所以事情总是更新,永远不会创建。

如何正确地将$方法传递给_submit()函数?!

答案 0 :(得分:3)

我现在对您的问题有了更好的了解 - 感谢您将更新发布到您的代码中。我正在更新并详细说明我的答案,以解释您的问题并提供一些解决方案。

我相信你知道,但是通过对与URI结构相关的一般MVC模式的基本回顾来介绍这一点并不会有什么坏处。也就是说,在site.com/home/survey/new的示例中,第一个段home是控制器类名,第二个段survey是控制器函数名,第三个段new (以及之后的任何段)是传递给survey()的ID或变量。 More here

您的代码无效,因为您在提交表单时从未通过URI将变量传递给survey(),因此URL中永远不会存在“new”,因此始终会设置$method更新”。所以,

  

“我如何将$方法传递给   _submit()函数是否正确?“

这样做有几种选择。每个人只需要确定是否存在用户 - >调查关系以便设置$method。然后,您可以将$method传递给相应的函数。对于下面的示例,我将假设用户只能进行一次调查。如果不是这种情况,您只需要考虑与唯一用户ID关联的唯一调查ID。

一种可能的情况是这样的(再次,这假设用户只能与一个调查相关联):

  1. 用户提交调查
  2. 提交表单后,请检查该用户是否已存在调查
  3. 如果是,请设置$method="update",否则设置$method="create"
  4. 继续将$method传递给其他必要的功能
  5. 替代解决方案可能如下所示:

    1. 在调用调查视图文件的控制器函数中,确定用户是否已存在记录。
    2. 将该数据传递到您的调查视图
    3. 在视图中,修改表单操作,以便在提交表单时将该数据(“create”或“update”)传递给survey()函数。
    4. survey()中,根据提供的数据设置$method
    5. 继续将$method传递给其他必要的功能
    6. 我将使用第一个选项作为示例并概述您需要的逻辑(原谅有些伪代码,但您会明白这一点):

      survey()函数:

      function survey() {
      
          // instead of determining whether "new" is part of the URI (which it never is),
          // check for an existing survey associated with the logged in user's ID
          $id = $this->session->userdata('id');
          $query = $this->db->get_where('Survey', array('user_id' => $id));
      
          // if the above query returns a result, set $method="update"
          // otherwise set $method="create"
          if ($query->num_rows() > 0) {
              $method="update";
          } else {
              $method="create";
          }
      
          // whatever other logic you need here
      
          // pass $method to survey_form()
          $this->survey_form_processing->survey_form($this->_container, $data, $method);
      }
      

      survey_form()函数:

      function survey_form($container, $data, $method) {
      
          // your other code here
      
          if ( $this->CI->validation->run() === FALSE ) {
              // Output any errors
              $this->CI->validation->output_errors();
          } else {
              // Submit form (w/ $method parameter - this comes from survey())
              $this->_submit($method);
          }
      
      }
      

      _submit()函数:

      function _submit($method) {
      
          // your other code here
      
          if ($method == "update") {
              // do something
          } elseif ($method == "create") {
              // do something else
          }
      
      }
      

      作为旁注,可能有更好的方法来构建您正在做的事情。例如,在我上面的伪代码中,数据库交互可能应该在模型中发生。但是为了清楚起见,它们包含在控制器中。我希望有所帮助!
