在CodeIgniter中選擇從MySQL DB顯示值的位置

Question

我想使用CodeIgniter顯示來自MySQL數據庫的值。在這裏，我使用SELECT查詢以使用WHERE條件比較多個值。

我想顯示從一頁到另一頁的檢查行值。我通過URL傳遞選中的值。在第二頁中，我從URL獲取值，並使用explode()函數分割值並使用for循環顯示。在這裏，值正確顯示。但是，將數組值傳遞給SELECT查詢時，它只顯示最後一行。

我想顯示數據庫中的所有檢查行。

例如，示例代碼：

<?php 

$id = $this->uri->segment(4); 
$arr = explode(',', $id); 
for ($kk = 0; $kk < count($arr); $kk++) { 
    echo $id_val13 = $arr[$kk]; 
    $basicUrl    = $this->config->item("basicUrl"); 
    $basicUrl['bread_crumb'] = $this->breadcrumb(); 
    $query     = $this->db->query("SELECT aa.id as id,customer_type_id,start_time,close_time,dd.name as customer_name,bb.name as vehicle_name,cc.name as driver_name,other_expensive,depature_city,destination_city,journey_status,payment,tour_file,DATE_FORMAT(aa.created_date, '%d/%m/%Y') as created_date FROM " . $this->tbl . " as aa 
           left join vehicle as bb on aa.vehicle_id=bb.id 
           left join driver as cc on aa.driver_id=cc.id 
           left join tbl_customer as dd on aa.customer_id=dd.id 
           WHERE aa.id = $id_val13"); 

    $result = array(); 

    if ($query->num_rows()) { 
     $i = 1; 
     foreach ($query->result() as $row) { 
      $result_row = array(); 
      $result_row[] = '<input type="checkbox" name="chk_id" id="chk_id" value="' . $row->id . '" />'; 
      $result_row[] = $row->id; 
      $result_row[] = $row->customer_name; 
      if ($row->customer_type_id == "1") 
       $result_row[] = "Tour"; 
      else if ($row->customer_type_id == "2") 
       $result_row[] = "Company"; 
      else if ($row->customer_type_id == "3") 
       $result_row[] = "Guest"; 
      $result_row[] = $row->driver_name; 
      $result_row[] = $row->vehicle_name; 

      $result_row[] = $row->destination_city; 
      $result_row[] = $row->start_time; 
      $result_row[] = $row->close_time; 
      $result_row[] = $row->payment; 
      $result_row[] = $row->other_expensive; 
      $result_row[] = $row->journey_status == "1" ? "Complete" : "On Progress"; 
      if ($row->tour_file != "") { 
       $result_row[] = '<a href="' . base_url('uploads/' . $row->tour_file) . '">' . $row->tour_file . '</a>'; 
      } else { 
       $result_row[] = "No File"; 
      } 
      $result_row[] = $row->created_date; 
      $action_btn = action_button("Edit", $row->id) . action_button("Delete", $row->id) . action_button("Select", $row->id); 
      $result_row[] = $action_btn; 

      $result[] = $result_row; 

      $i++;         
     }       
    }     
} 


$tbl_header = array(
    "", 
    "S NO", 
    "Customer Name", 
    "Type", 
    "Driver Name", 
    'Vehicle Name', 
    "Destination City", 
    "Start Time", 
    "Close Time", 
    "Rupee", 
    "Other Expensive", 
    "Journey Status", 
    "Itinerary", 
    "Created Date", 
    array(
     "Edit", 
     "Delete" 
    ) 
); 
$basicUrl['table'] = $this->makeTable($result, $tbl_header, $bool = TRUE); 

$this->parser->parse("admin/center", $basicUrl); 

?> 

例如：

$array = array("1","2","6"); 

通常使用explode()和for環，它顯示所有的值。當我使用CodeIgniter使用select查詢時，它僅顯示最後一行。

試試這個（我爲循環之前已經定義$result）同樣，這不是用你這樣的代碼使用的控制器和模型做所有的邏輯和數據庫的工作一個很好的做法....

<?php 

    $id = $this->uri->segment(4); 
    $arr = explode(',', $id); 
    $result=array(); 
    for ($kk = 0; $kk < count($arr); $kk++) 
     { 
      echo $id_val13 = $arr[$kk]; 
      $basicUrl = $this->config->item("basicUrl"); 
      $basicUrl['bread_crumb'] = $this->breadcrumb(); 
      $query=$this->db->query("SELECT aa.id as id,customer_type_id,start_time,close_time,dd.name as customer_name,bb.name as vehicle_name,cc.name as driver_name,other_expensive,depature_city,destination_city,journey_status,payment,tour_file,DATE_FORMAT(aa.created_date, '%d/%m/%Y') as created_date FROM ".$this->tbl." as aa 
          left join vehicle as bb on aa.vehicle_id=bb.id 
          left join driver as cc on aa.driver_id=cc.id 
          left join tbl_customer as dd on aa.customer_id=dd.id 
          WHERE aa.id = $id_val13"); 


    if($query->num_rows()){ 
     $i=1; 
     foreach($query->result() as $row){ 
      $result_row=array(); 
      $result_row[]='<input type="checkbox" name="chk_id" id="chk_id" value="'.$row->id.'" />';

      $result[]=$result_row; 


      $i++; 


    } 


     } 


     }
