Count of categories and subcategories PHP count

[nepoverljiv]

Anyone can help me?

 

<?php

$tbl_name="menu";

$kategorije = mysql_query("SELECT * FROM $tbl_name WHERE Left(menu_name, 1) BETWEEN 'A' AND 'M' ORDER BY menu_name ASC");

if (!$kategorije) {

die("Database query failed: " . mysql_error());

}

 

while ($row=mysql_fetch_array( $kategorije )) {

echo "<div id=lista-header><h4>{$row["menu_name"]}</h4></div>";

$id_sub=$row['id_menu'];

$podkategorije = mysql_query("SELECT * FROM submenu WHERE id_menu=$id_sub ORDER BY sub_name ASC", $connection);

if (!$podkategorije) {

die("Database query failed: " . mysql_error());

}

echo "<ul class=\"pod\">";

while ($pod=mysql_fetch_array( $podkategorije )) {

echo "<li><a href=index.php?=podkate?".$pod["id_sub"]." class=black>{$pod["sub_name"]}</a><hr size=1 align=left width=100px color=#cccccc></li>";

}

echo "</ul>";

}

 

 

?>

 

In this way, I get list with categories and hes subcategories. How to count how many subcategories have each categories, and count how many articles have each categories?

 

Example (I wanna get this kind of look):

 

Categories name (3)

subcategoriesname (2)

subcategoriesname (4)

subcategoriesname (7)

 

Categories name (5)

subcategoriesname (1)

subcategoriesname (14)

subcategoriesname (9)

subcategoriesname (2)

subcategoriesname (

 

 

Categories name (2)

subcategoriesname (28)

subcategoriesname (17)

 

Where the numbers represent how many categories and sub-items have articles

You could nest query iterations as such:

 

$sql = 'SELECT cat_id, cat_name FROM main_categories';
$result1 = mysql_query($sql);
while ($row1 = mysql_fetch_assoc($result1)){
   $sql = "SELECT sub_cat_id, cat_name FROM sub_categories WHERE main_cat_id={$row1['cat_id']}";
   $result2 = mysql_query($sql);
   echo $row1['cat_name'].' ('.mysql_num_rows($result2).')';
   while ($row2 = mysql_fetch_assoc($result2)){
       $sql = "SELECT COUNT(topic) Topic_Count FROM cat_topics WHERE sub_cat_id={$row2['sub_cat_id']}";
       $result3 = mysql_query($sql);
       $row3 = mysql_fetch_assoc($result3);
       echo $row2['cat_name'].' ('.$row3['Topic_Count'].')';
   }
}

 

That's a general solution.
