針對每個單獨的東西運行兩個查詢

Question

對不起，關於這個蹩腳的標題，但我真的不知道如何解釋它！

基本上，我想從表中查詢遊戲類別，然後從另一個表中查詢遊戲，這些遊戲等同於從類別表中查詢的類別的類別。

讓我到目前爲止？

這是我到目前爲止的代碼...

$get_categories_query = mysql_query(" 
    SELECT * 
    FROM game_categories 
ORDER BY category_name ASC"); 
while ($row = mysql_fetch_array($get_categories_query)) { 
    $category_name  = $row['category_name']; 
    $get_category_games = mysql_query(" 
    SELECT * 
     FROM games 
    WHERE category = '$category_name' 
    ORDER BY RAND() LIMIT 5"); 
    while ($row = mysql_fetch_array($get_category_games)) { 
    $category_game_id = $row['id']; 
    $category_game_title = $row['game_title']; 
    $category_game_display .= '<li><img 
     class="category_module_img" 
     src="http://www.game.assets.buddyweb.me/' . 
     $category_game_id . 
     '/_thumb_100x100.png"></li>'; 
    } 
    $category_display .= '<div class = "category_module"> 
    <h4>'.$category_name.'</h4> 
    '.$category_game_display.' 
    <div class="play_more_btn">More</div> 
    </div>'; 
} 

但我從得到的是從該列表中的第一個類別查詢中出現的每一場比賽。

我認爲問題是$行變量。

試試這個：在內部，而

$get_categories_query = mysql_query("SELECT * FROM game_categories ORDER BY category_name ASC"); 

while($row = mysql_fetch_array($get_categories_query)) 
{ 
    $category_name = $row['category_name']; 
    $get_category_games = mysql_query("SELECT * FROM games WHERE category = '$category_name' ORDER BY RAND() LIMIT 5"); 
    $category_game_display = false; // new!! 

    while($row_cat = mysql_fetch_array($get_category_games)) 
    { 
     $category_game_id = $row_cat['id']; 
     $category_game_title = $row_cat['game_title']; 
     $category_game_display .= '<li><img class = "category_module_img" src = "http://www.game.assets.buddyweb.me/'.$category_game_id.'/_thumb_100x100.png"></li>'; 
    } 

    $category_display .= '<div class = "category_module"><h4>'.$category_name.'</h4>'.$category_game_display.'<div class = "play_more_btn">More</div></div>'; 
}
