含量有正確的模塊位置

Question

我有一個控制器，顯示我的每個位置

Array 
(
    [0] => Array 
     (
      [layout_module_id] => 1 
      [layout_id] => 1 
      [module_id] => 1 
      [position] => column_left 
      [sort_order] => 1 
     ) 

    [1] => Array 
     (
      [layout_module_id] => 2 
      [layout_id] => 1 
      [module_id] => 2 
      [position] => column_left 
      [sort_order] => 2 
     ) 

) 

上述模塊目前我只有兩個模塊設置和在列左邊的位置沒有顯示。

由於位置視圖位於foreach循環的外側，即使未設置該位置，它們也正在拾取該模塊？如圖所示。

問：我怎樣才能確保該模塊將只在其設定位置視圖顯示。

public function index() { 
    $layout_id = $this->getlayoutID($this->router->class); 

    $modules = $this->getlayoutsmodule($layout_id); 

    echo '<pre>'; 
    print_r($modules); 
    echo "</pre>"; 

    $data['modules'] = array(); 

    foreach ($modules as $module) { 
     $this->load->library('module/question_help'); 
     $data['modules'][] = $this->load->view('module/question_help', $this->question_help->set(), TRUE); 
    } 

    // Position Views 
    $data['column_left'] = $this->load->view('column_left', $data, TRUE); 
    $data['column_right'] = $this->load->view('column_right', $data, TRUE); 
    $data['content_top'] = $this->load->view('content_top', $data, TRUE); 
    $data['content_bottom'] = $this->load->view('content_bottom', $data, TRUE); 

    // Main view 
    $this->load->view('welcome_message', $data); 
} 

public function getlayoutsmodule($layout_id) { 
    $this->db->select('*'); 
    $this->db->from('layouts_module'); 
    $this->db->where('layout_id', $layout_id); 
    $query = $this->db->get(); 

    if ($query->num_rows() > 0) { 
     return $query->result_array(); 
    } 
} 

每個位置的看法具有相同的foreach循環

<?php if ($modules) { ?> 
<?php foreach ($modules as $module) { ?> 
<?php echo $module;?> 
<?php } ?> 
<?php }?>

<div class="container"> 
    <div class="row"> 
    <?php echo $column_left; ?> 

    <?php if ($column_left && $column_right) { ?> 
    <?php $class = 'col-sm-6'; ?> 
    <?php } elseif ($column_left || $column_right) { ?> 
    <?php $class = 'col-sm-9'; ?> 
    <?php } else { ?> 
    <?php $class = 'col-sm-12'; ?> 
    <?php } ?> 

    <div id="content" class="<?php echo $class; ?>"> 
    <?php echo $content_top; ?>

    <?php echo $content_bottom; ?> 
    </div> 
    <?php echo $column_right; ?></div> 
</div>

得到它的工作，我不得不使用foreach switch語句

<?php 

class Welcome extends CI_Controller { 

    public function index() { 
     $layout_id = $this->getlayoutID($this->router->class); 

     $column_left = ''; 
     $column_right = ''; 
     $content_top = ''; 
     $content_bottom = ''; 
     $position = array('column_left', 'column_right', 'content_top', 'content_bottom'); 

     foreach ($position as $key) { 

      switch ($key) { 
       case 'column_left': 

        $data['modules'] = array(); 

        $layout_module_results = $this->getlayoutsmodule($layout_id, 'column_left'); 

        if (!empty($layout_module_results)) { 
         foreach ($layout_module_results as $layout_module_result) { 
          $data['modules'][] = array(
           'position' => $layout_module_result['position'] 
          ); 
         } 
        } 

        $column_left = $this->load->view('column_left', $data, TRUE); 

        break; 

       case 'column_right': 

        $data['modules'] = array(); 

        $layout_module_results = $this->getlayoutsmodule($layout_id, 'column_right'); 

        if (!empty($layout_module_results)) { 
         foreach ($layout_module_results as $layout_module_result) { 
          $data['modules'][] = array(
           'position' => $layout_module_result['position'] 
          ); 
         } 
        } 

        $column_right = $this->load->view('column_right', $data, TRUE); 

        break; 

       case 'content_top': 

        $data['modules'] = array(); 

        $layout_module_results = $this->getlayoutsmodule($layout_id, 'content_top'); 

        if (!empty($layout_module_results)) { 
         foreach ($layout_module_results as $layout_module_result) { 
          $data['modules'][] = array(
           'position' => $layout_module_result['position'] 
          ); 
         } 
        } 

        $content_top = $this->load->view('content_top', $data, TRUE); 

        break; 

       case 'content_bottom': 

        $data['modules'] = array(); 

        $layout_module_results = $this->getlayoutsmodule($layout_id, 'content_bottom'); 

        if (!empty($layout_module_results)) { 
         foreach ($layout_module_results as $layout_module_result) { 
          $data['modules'][] = array(
           'position' => $layout_module_result['position'] 
          ); 
         } 
        } 

        $content_bottom = $this->load->view('content_bottom', $data, TRUE); 

        break; 
      } 

     } 

     $data['column_left'] = $column_left; 
     $data['column_right'] = $column_right; 
     $data['content_top'] = $content_top; 
     $data['content_bottom'] = $content_bottom; 

     $this->load->view('welcome_message', $data); 
    } 
}
