如何顯示類別的項目？

Question

我需要顯示每個類別的項目。我使用smarty模板。所以我得到這樣的類別：

{foreach $news as $article} 
    <div class="panel panel-info"> 
     <div class="panel-heading">{$article["name"]}</div> 
     <div class="panel-body"> 
      "Here I need to display Items that have FOREIGN KEY 'category_id'" 
     </div> 
    </div> 
{/foreach} 

是否我應該得到一個類別的ID和如何顯示它？ It's a category list with ID

我想提高我的問題 - 這裏有一些鏈接到我的Controller。我試圖增加更多的鏈接，但是我的聲譽很低，我無法做到。請嘗試看看我做錯了什麼？

<?php 
$lists = ''; 
$query = "your query example" - mysqli_query($conn,"select * from article"); 
if(!$mysqli_num_rows<0){ 
while($row = mysqli_fetch_array($query,MYSQLI_ASSOC)){ 
    $id = $row["category_id"]; 
    $name = $row["name"]; 

    $lists .= '<div class="panel panel-info"> 
     <div class="panel-heading">'.$name.'</div> 
     <div class="panel-body"> 
      "Here I need to display Items that have FOREIGN KEY '.$id.'" 
     </div> 
    </div>'; 
} 

    echo $lists; 
} 


?>
