PHP menu retrieve parent/child

[MNO]

Hi there! I'm having some problems in this code... (plaincart)

 

I have 2 pages:

 

 1. index.php (is my main page where is the left menu);

 2. functions.php (where is the PHP functions, necessary to build

    the menu at index.php).

 

 

----------

 

 

At this point all code is correct...

the main menu is showing like this...

 

 1. Women

 2. Men

 3. Children

 

 

----------

 

 

When I click, for example at "Women", the menu is showing like this...

 

 1. Women

 - Coats

 - Blazers

 - Dresses

 2. Men

 3. Children

 

 

----------

 

But, my big question is: how to show the menu always like this:

 

 1. Women

 - Coats

 - Blazers

 - Dresses

 2. Men

 - Coats

 - Blazers

 - Shirts

 3. Children

 - Boys

 - Girls

 

 

----------

 

 

**QUESTION:** How to show always the parent id of the main categories... Perhaps a little modification in functions.php > formatCategories(); ?

 

 

 

******************* index.php ******************* 

 

    $catId  = (isset($_GET['c']) && $_GET['c'] != '1') ? $_GET['c'] : 0;



    // get all categories

    $categories = fetchCategories();

    

    // format the categories for display

    $categories = formatCategories($categories, $catId);

    ?>

    <ul>

    <li><a href="<?php echo $_SERVER['PHP_SELF']; ?>">All Category</a></li>

    <?php

    foreach ($categories as $category) {

     extract($category);

     // now we have $cat_id, $cat_parent_id, $cat_name

     

     $level = ($cat_parent_id == 0) ? 1 : 2;

        $url   = $_SERVER['PHP_SELF'] . "?c=$cat_id";

    

     // for second level categories we print extra spaces to give

     // indentation look

     if ($level == 2) {

     $cat_name = '    » ' . $cat_name;

     }

     

     // assign id="current" for the currently selected category

     // this will highlight the category name

     $listId = '';

     if ($cat_id == $catId) {

     $listId = ' id="current"';

     }

    ?>

    <li<?php echo $listId; ?>><a href="<?php echo $url; ?>"><?php echo $cat_name; ?></a></li>

    <?php

    }

    ?>

    </ul>

 

******************* functions.php ******************* 

 

   

 function formatCategories($categories, $parentId)

    {

     // $navCat stores all children categories

     // of $parentId

     $navCat = array();

     

     // expand only the categories with the same parent id

     // all other remain compact

     $ids = array();

     foreach ($categories as $category) {

     if ($category['cat_parent_id'] == $parentId) {

     $navCat[] = $category;

     }

     

     // save the ids for later use

     $ids[$category['cat_id']] = $category;

     } 

    

     $tempParentId = $parentId;

     

     // keep looping until we found the 

     // category where the parent id is 0

     while ($tempParentId != 0) {

     $parent    = array($ids[$tempParentId]);

     $currentId = $parent[0]['cat_id'];

    

     // get all categories on the same level as the parent

     $tempParentId = $ids[$tempParentId]['cat_parent_id'];

     foreach ($categories as $category) {

         // found one category on the same level as parent

     // put in $parent if it's not already in it

     if ($category['cat_parent_id'] == $tempParentId && !in_array($category, $parent)) {

     $parent[] = $category;

     }

     }

     

     // sort the category alphabetically

     array_multisort($parent);

     

     // merge parent and child

     $n = count($parent);

     $navCat2 = array();

     for ($i = 0; $i < $n; $i++) {

     $navCat2[] = $parent[$i];

     if ($parent[$i]['cat_id'] == $currentId) {

     $navCat2 = array_merge($navCat2, $navCat);

     }

     }

     

     $navCat = $navCat2;

     }

    

    

     return $navCat;

    }
