【问题描述】：

我是 codeigniter 的新手，正在尝试将 form_dropdown 数据插入数据库，但我无法将所选选项插入数据库。

这是我的模型：

public function insertUser()
  
        $data1 = array(
            'id'=>$this->input->post('id'),
            'full_name'=>$this->input->post('full_name'),
            'email'=>$this->input->post('email'),
            'contact_no'=>$this->input->post('contact_no'),
            'role'=>$this->roles[0], 
            'status'=>$this->status[0]
        );
        $this->db->insert('users',$data1);
        $data2['user_id']=$this->db->insert_id();
        $data2 = array(
            'type_of_paper'=>$this->input->post('type_of_paper'),
            'deadline'=>$this->input->post('deadline'),
            'acadmic_level'=>$this->input->post('acadmic_level'),
            'quality'=>$this->input->post('quality'),
            'noofpage'=>$this->input->post('noofpage'),
            'subject_area'=>$this->input->post('subject_area')
        );            
        $this->db->insert('orders',$data2);
        return $this->db->insert_id();

这是我的控制器：

public function order()

    $data['title']='Order';
    $data['page']='order';
    $data['type_of_paper'] = $this->writer_model->getTypeOfPaper();
    $data['deadline'] = $this->writer_model->getDeadline();
    $data['prices'] = $this->writer_model->getPrice();
    $data['acadmic_level']=$this->writer_model->getAcadmicLevel();
    $data['quality']=$this->writer_model->getQuality();
    $data['subject_area']=$this->writer_model->getSubjectArea();
    $data['currencies']=$this->writer_model->getCurrency();

    $this->form_validation->set_rules('full_name', 'Full Name', 'trim|required|min_length[5]|max_length[50]|is_unique[users.full_name]',
    array(
            'required'      => 'You have not provided %s.',
            'is_unique'     => 'This %s already exists.'
    ));
    $this->form_validation->set_rules('email', 'Email', 'trim|required|valid_email|is_unique[users.email]',
    array(
            'required'      => 'You have not provided correct %s.',
            'is_unique'     => 'This %s already exists.'
    ));
    $this->form_validation->set_rules('contact_no', 'Contact No', 'trim|required');    
    $this->form_validation->set_rules('type_of_paper', 'Type Of Paper', 'trim|required');
    $this->form_validation->set_rules('deadline', 'Deadline', 'trim|required');
    $this->form_validation->set_rules('acadmic_level', 'Acadmic Level', 'trim|required');
    $this->form_validation->set_rules('quality', 'Quality', 'trim|required');
    $this->form_validation->set_rules('noofpage', 'No Of Pages', 'trim|required');
    $this->form_validation->set_rules('subject_area', 'Subject Area', 'trim|required');

    if ($this->form_validation->run() == FALSE) 
       
        $this->load->view('header', $data);
        $this->load->view('navbar', $data);
        $this->load->view('order', $data);
        $this->load->view('footer', $data);
    else
                    
        if($this->user_model->isDuplicate($this->input->post('email')))
        
            $this->session->set_flashdata('flash_message', 'User email already exists');
            redirect(site_url().'/home/login');
        else
        
            $config=array(
                'protocol' => 'smtp',
                'smtp_host' => 'ssl://smtp.googlemail.com',
                'smtp_port' => 465,
                'smtp_user' => '',
                'smtp_pass' => '',
                'mailtype' => 'html' 
                );

            $clean = $this->security->xss_clean($this->input->post(NULL, TRUE));
            $id = $this->user_model->insertUser($clean); 
            $token = $this->user_model->insertToken($id);                                        

            $qstring = $this->base64url_encode($token);                      
            $url = site_url() . '/home/complete/token/' . $qstring;
            $link = $url; 


            $message = '';                     
            $message .= 'You have signed up with our website.
                         Please click here to verify your email address:'. $link;   

            $this->load->library('email',$config);
            $this->email->set_newline("\r\n");
            $this->email->from('','Gourav shukla');
            $this->email->to($this->input->post('email'));
            $this->email->subject('This is an email Test');
            $this->email->message($message);
            $this->email->send();

            /*if($this->email->send();)
            
                echo 'Your email was sent, fool.';
            else
            
                show_error($this->email->print_debugger());
                                  

            echo $message; send this in email
            exit;*/


        ;

当我运行这段代码时，我得到了这个输出：

output image

但我想将选项名称存储到数据库中，而不是选项中的值。 请解决这个问题。 提前致谢。

【问题讨论】：

当您获取帖子数据时，然后从数据库中获取所有选项名称数据，然后匹配它的值并更改帖子数组中的值。

【参考方案1】：

我从你的最后两行得到的数据和图像正在插入数据库但值正在插入并且你想要插入名称，

如果我正确的话， 你必须在选项值中使用你的名字，比如

<option value="name">name or anything you want</option>

在 form_dropdown 中

$style=array("id"=>"any_id","class"=>"any_class");
$dd_data=array();
$dd_data['']="-select-";
foreach($data as $row) // $data coming from server

$dd_data[$row['name']]=$row['name or anything'] // $row['name'] names that you wants to add into database

echo form_dropdown('field_name',$dd_data,'',$style);

此代码只是一个示例，未经过测试。
