Codeigniter Pagination 分頁實作

CI官方說明 :https://codeigniter.org.tw/userguide3/libraries/pagination.html?highlight=page#id5

$this->load->library('pagination');

$config['base_url'] = 'http://example.com/index.php/test/page/'; //要產生頁籤的網址
$config['total_rows'] = 200; //資料總共幾筆
$config['per_page'] = 20; //一次想要顯示幾筆

$this->pagination->initialize($config);

echo $this->pagination->create_links(); //這一行就是分頁的html

分頁bar這樣就有了

但是還要跟資料連動

因此我會加一這一行

$config['page_query_string'] = TRUE;

加了這行後你可以在觀察網址上會多出per_page參數

這個參數的意思就是你的資料是從第幾筆開始的

所以你只要把這個參數和一次要幾筆的參數給你取資料的function就可以跟分頁頁籤有連動了

ex:

        $this->load->library('pagination'); // 載入

        //從第幾筆開始
        $per_page = $this->input->get_post('per_page');

        //一頁幾筆
        $qty = 2;
        if ($per_page == "") {

            //因為第一頁沒有這個參數，所以要自己補上
            $per_page = 0;
        }
        // from menu
        
        $res = $this->mod_product->get_list(get_temples_id(),$qty,$per_page);

        $mycount = count($this->mod_product->get_list(get_temples_id()));

        $config['base_url'] = site_url().'pages/store_product_list';
        $config['total_rows'] = $mycount;
        $config['per_page'] = $qty;
        $config['num_links'] = 2; //頁籤中間一次有幾個按鈕
        $config['page_query_string'] = TRUE;
                    
        $this->pagination->initialize($config);

        $pagenation = $this->pagination->create_links();

        $data = array('list' => $res,'pagenation'=>$pagenation );

        $this->load->view('pages/store_product_list',$data);
