Question

I am using smarty php template and sql server

I have the following tables :

table 1 (anime_pages) : contains data

table 2 (anime_genres) : contains categories

table 3 (genres_pages) : contains relationship between data and category

I am trying to show 3 random categories with 10 data results from that category.

I have the following php code right now :

$randomcsql = $db->query("SELECT * FROM anime_genres ORDER BY RAND() LIMIT 3");
while($ft5 = $db->fetch_array($randomcsql))
{
    $randomcats[] = $ft5; 
}
$smarty->assign('randomcats' , $randomcats);
$db->free_result($randomcsql);

$animecatssql = $db->query("SELECT * FROM anime_pages JOIN genres_pages ON anime_pages.id = genres_pages.genre_id  WHERE genres_pages.genre_id = (".$ft5['id'].") LIMIT 10 ");
while($ft6 = $db->fetch_array($animecatssql))
{
    $animecats[] = $ft6; 
}
$smarty->assign('animecats' , $animecats);
$db->free_result($animecatssql);

the problem is with (".$ft5['id'].") it is not giving me any result and If I replaced it with a number … I will get a duplicated result (every data is duplicated twice)

How can I solve the problem ?

Is there a better code to use ?

Answer 1

I solved it by showing on random result instead of three

$randomcsql = $db->query("SELECT * FROM anime_genres ORDER BY RAND() LIMIT 1");
   while($ft5 = $db->fetch_array($randomcsql))
   {
   $randomcats[] = $ft5; 
   $animecatssql = $db->query("SELECT * FROM anime_pages JOIN genres_pages ON anime_pages.id = genres_pages.genre_id  WHERE genres_pages.genre_id = (".$ft5['id'].") LIMIT 10 ");
   while($ft6 = $db->fetch_array($animecatssql))
   {
   $animecats[] = $ft6; 
   }
   }
   $smarty->assign('randomcats' , $randomcats);
   $db->free_result($randomcsql);
   $smarty->assign('animecats' , $animecats);
   $db->free_result($animecatssql);
