针对每个单独的东西运行两个查询

Question

对不起，关于这个蹩脚的标题，但我真的不知道如何解释它！

基本上，我想从表中查询游戏类别，然后从另一个表中查询游戏，这些游戏等同于从类别表中查询的类别的类别。

让我到目前为止？

这是我到目前为止的代码...

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

但我从得到的是从该列表中的第一个类别查询中出现的每一场比赛。

我认为问题是$行变量。

试试这个：在内部，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>'; 
}
