Question

在Codeigniter中我有add_main_products函数将图像上传到数据库，在此之前我想验证类似<input type="text" name="product_name">的文本字段。我如何在add_main_products()函数

中执行此操作

   function add_main_products(){

        $config['upload_path'] = 'application/views/uploads/';            
        $config['allowed_types'] = 'gif|jpg|png|jpeg';      
        $this->load->library('upload', $config);    

        if (!$this->upload->do_upload('userfile')) {

            $error = array('error' => $this->upload->display_errors());
            $this->load->view('admin/admin_add_mainproduct', $error);

        } else {

            $this->mod_products->add_main_product($this->upload->data());
            $data = array('upload_data' => $this->upload->data());
            $this->load->view('admin/admin_add_mainproduct', $data);  }    

    }

Answer 1

试试这个......

function add_main_products()
{
   $this->form_validation->set_rules('product_name', $this->lang->line('product_add_name'), 'required|xss_clean');

   if ($this->form_validation->run() == TRUE) 
   {
     // Put your upload code
   }
}

并在$this->load->library('form_validation');

中加载此_construct function库

你可以做这样的事情

     function add_main_products(){

        $this->form_validation->set_rules('product_name', 'Product Name', 'required');    

    if ($this->form_validation->run() == FALSE){
            $this->load->view('admin/admin_add_mainproduct');
        }
           else{

             $config['upload_path'] = 'application/views/uploads/';            
             $config['allowed_types'] = 'gif|jpg|png|jpeg';            
             $this->load->library('upload', $config);

             if (! $this->upload->do_upload()){
                $error['error'] = array('error' => $this->upload->display_errors());
                $this->load->view('admin/admin_add_mainproduct', $error);
                return FALSE;
                }

               $this->mod_products->add_main_product($this->upload->data());
               $data = array('upload_data' => $this->upload->data());
               $this->load->view('admin/admin_add_mainproduct', $data);
         }

}
