Running two queries for each individual thing - php

Question

Sorry about the lame title, but I really don't know how to explain it!
Basically, I want to query the game categories from a table, then query games from another table which equal the category of the category queried from the categories table.
Got me so far?
This is the code I have so far...
$get_categories_query = mysql_query("
SELECT *
FROM game_categories
ORDER BY category_name ASC");
while ($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>';
}
But what I get from that is every game appearing from the query from the first category in the list.

I think the problem is the $row variable.
Try this:
$get_categories_query = mysql_query("SELECT * FROM game_categories ORDER BY category_name ASC");
while($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>';
}
