笨：分頁+表庫（沒有工作）

Question

我需要幫助，我的代碼點火器app..i似乎無法找出是什麼導致分頁不工作

這裏是我的控制器

$limit = 15; 
     $uri_segment = 4; 
     $this->load->helper('string'); 

     $offset = $this->uri->segment($uri_segment); 
     log_message('error',date('Y-m-d H:i:s', time())); 
     //load 
     //$products = $this->Products_model->get_all(); 
     $products = $this->Products_model->get_products($limit, $uri_segment); 
     //var_dump($products); 

     log_message('error', $products); 

     //pagination 
     $this->load->library('pagination'); 
     $config['base_url'] = site_url('admin/products/index/'); 
     $config['total_rows'] = $this->Products_model->count_all(); 
     $config['per_page'] = $limit; 
     $config['uri_segment'] = $uri_segment; 
     $this->pagination->initialize($config); 

     $data['pagination'] = $this->pagination->create_links(); 

     //table 
     $this->load->library('table'); 
     $this->table->set_empty(" "); 
     $this->table->set_heading('ID', 'Product','Category', 'Actions'); 
     $i = 0 + $offset; 
     foreach ($products as $product){ 
      ++$i; 
      $this->table->add_row($product->id, $product->title, $this->Categories_model->get_by_id($product->category_id)->title, 
       anchor('/admin/products/update/'.$product->id,'update',array('class'=>'update')).' '. 
       anchor('/admin/products/delete/'.$product->id,'delete',array('class'=>'delete','onclick'=>"return confirm('Are you sure want to delete this product?')")) 
      ); 
     } 
     $data['table'] = $this->table->generate(); 

     //load template 
     $this->products_list(); 
     $this->products_template(); 
     $this->template->build('products/productList', $data); 

這裏是我的模型

function get_products($num, $offset) { 
    return $this->db->get($this->tbl_products, $num, $offset)->result();  
} 

它生成的鏈接，但那麼它不會加載下一組記錄..任何更正上面的代碼？

謝謝！

Answer 1

您應該將頁面放在表格中，而不是整個表格。分頁只是填充鏈接，但不會對數據進行任何更改，這是您的責任。

請更改：

 $products = $this->Products_model->get_all(); 

有：

 $products = $this->Products_model->get_page($Offset, $this->limit); // It's not clear where do you define limit. 

，並在模型中做出選擇propper：

function get_page($offset, $limit){ 
    return $this->db->get($this->tbl_products, $limit, $offset)->result(); 
} 

Answer 2

你應該確保你的極限（$這個 - >限制）具有良好的數據（只有整數）。如果您打開了查詢字符串，則可能會將字符串'& per_page ='傳遞到您的模型上。如果用正則表達式或str_replace清理$ this-> limit。

Answer 3

這是你的錯誤

$products = $this->Products_model->get_products($limit, $uri_segment); 

$limit=the number of data you want to show in per page, 

$offset=the data number start from. 

所以點擊每個鏈接，你必須改變偏移值來顯示數據。試試這個

if($this->uri->segment(uri_segment) > 0){ 

       $offset=$this->uri->segment($uri_segment); 

      } 
      else{ 
       $offset=0; 

      } 
$products = $this->Products_model->get_products($limit, $offset);
