php - Codeigniter：如何在重定向中传递搜索词

问题描述

我使用 PHP 和 MySQL 用 codeigniter 做了一个简单的项目。该项目使用户能够通过添加新产品和更新每个库存来管理他的仓库。现在，当用户搜索产品并更新库存值时，应用程序会更新数据库并刷新页面并显示所有产品。有没有办法传递他使用的搜索词，甚至更好地传递他在重定向中更改的产品。非常感谢。

function prevazia($param1 = '', $param2 = '', $param3 = '')
    {
        if ($this->session->userdata('admin_login') != 1)
            redirect(base_url() . 'index.php?login');
        if ($param1 == 'edit') 
        {
            $data['type']    = $this->input->post('type');   
            $data['color']   = $this->input->post('color');
            $addition   = $this->input->post('addition');
            $data['stock']   = $this->input->post('stock') + $addition;
            $data['stock_alert']   = $this->input->post('stock_alert');
            //-----------------------------------------
            include('dbc.php');
            mysqli_query($conn,"SET character_set_results = 'utf8', character_set_client = 'utf8', character_set_connection = 'utf8', character_set_database = 'utf8', character_set_server = 'utf8'");
            $sql9 = "SELECT * FROM prevazia_log order by id desc LIMIT 1";          
            $result = mysqli_query($conn, $sql9);
            if ($result->num_rows > 0) 
            {
                while($row = $result->fetch_assoc()) 
                {
                    $last_id=$row['id']+1;
                }
            }
            date_default_timezone_set('Europe/Athens');
            //$result6 =  mysqli_query($conn, $sql);
            //$additionDate = DateTime::createFromFormat('d/m/Y H:i');
            //$myAdditionDate = $additionDate->format('Y-m-d H:i');
            $log['id']                  = $last_id;
            $log['user']                = $this->session->userdata('name');
            $log['create_timestamp']    = date("d-m-y  h:i:sa");
            $log['type']                = $this->input->post('type');
            $log['color']               = $this->input->post('color');
            $log['previous_stock']      = $this->input->post('stock');
            $log['addition']            = $this->input->post('addition');
            $log['new_stock']           = $this->input->post('stock') + $this->input->post('addition');
            //--------------------
            //$data['role']   = $this->input->post('role');
            $this->db->insert('prevazia_log', $log);
            $this->db->where('id', $param2);
            $this->db->update('prevazia', $data);
            // UPLOAD IMAGE FILE
            $this->session->set_flashdata('flash_message', translate('informations_updated'));
            redirect(base_url() . 'index.php?admin/prevazia', 'refresh');
        }
        if ($param1 == 'delete') 
        {
            $this->db->where('id', $param2);
            $this->db->delete('prevazia');
            $this->session->set_flashdata('flash_message', translate('data_deleted'));
            redirect(base_url() . 'index.php?admin/prevazia', 'refresh');
        }
        $page_data['page_name']  = 'prevazia';
        $page_data['page_title'] = 'Πρεβάζια';
        $page_data['prevazia']  = $this->db->get_where('prevazia', array('active'=> $GLOBALS['flag']))->result_array();
        $this->load->view('backend/index', $page_data);
    }

编辑：最好是如果我可以传递 $data['type'] 和 $data['color']，那么当它重定向时，它会将这些值传递给搜索框。

解决方案

如果您使用带有方法 post 的表单提交，您应该通过视图返回搜索参数

$data['search_param'] =  $post['search_param'];
$this->load->view('view_page', $data);

<input name="search_param"  value="<?php echo !empty($search_param) ? $search_param : ''?>">
