Just got this code working for 2 levels of my menu. But I want it to work with unlimited levels.
Do any of you guys have an idea where to start?
Right now if I type in more levels in the database it says "Undefined index Linnk & Label Line 29", and the new parent that has been entered does not show up.
$sql = "SELECT id, label, link_url, parent_id FROM dyn_menu ORDER BY parent_id, id ASC";
$items = mysql_query($sql);
while ($obj = mysql_fetch_object($items)) {
if ($obj->parent_id == 0) {
$parent_menu[$obj->id]['label'] = $obj->label;
$parent_menu[$obj->id]['link'] = $obj->link_url;
} else {
$sub_menu[$obj->id]['parent'] = $obj->parent_id;
$sub_menu[$obj->id]['label'] = $obj->label;
$sub_menu[$obj->id]['link'] = $obj->link_url;
if (!isset($parent_menu[$obj->parent_id]['count'])) {
$parent_menu[$obj->parent_id]['count'] = 0;
}
$parent_menu[$obj->parent_id]['count']++;
}
}
mysql_free_result($items);
function dyn_menu($parent_array, $sub_array, $qs_val = "menu", $main_id = "nav", $sub_id = "subnav", $extra_style = "foldout") {
$menu = "<ul id=\"".$main_id."\">\n";
foreach ($parent_array as $pkey => $pval) {
if (!empty($pval['count'])) {
$menu .= " <li><a class=\"".$extra_style."\" href=\"".$pval['link']."?".$qs_val."=".$pkey."\">".$pval['label']."</a></li>\n";
} else {
$menu .= " <li>".$pval['label']."</li>\n";
}
if (!empty($_REQUEST[$qs_val])) {
$menu .= "<ul id=\"".$sub_id."\">\n";
foreach ($sub_array as $sval) {
if ($pkey == $_REQUEST[$qs_val] && $pkey == $sval['parent']) {
$menu .= "<li>".$sval['label']."</li>\n";
}
}
$menu .= "</ul>\n";
}
}
$menu .= "</ul>\n";
return $menu;
}
function rebuild_link($link, $parent_var, $parent_val) {
$link_parts = explode("?", $link);
$base_var = "?".$parent_var."=".$parent_val;
if (!empty($link_parts[1])) {
$link_parts[1] = str_replace("&", "##", $link_parts[1]);
$parts = explode("##", $link_parts[1]);
$newParts = array();
foreach ($parts as $val) {
$val_parts = explode("=", $val);
if ($val_parts[0] != $parent_var) {
array_push($newParts, $val);
}
}
if (count($newParts) != 0) {
$qs = "&".implode("&", $newParts);
}
return $link_parts[0].$base_var.$qs;
} else {
return $link_parts[0].$base_var;
}
}
echo dyn_menu($parent_menu, $sub_menu, "menu", "nav", "subnav");
In order to do this, you'll want to use a recursive function to handle your array -> list transformation.
Here's an example:
<?php
function arrToUl($arr) {
$out = '<ul>';
foreach($arr as $key=>$val) {
$out .= '<li>';
$out .= is_array($val) ? arrToUl($val) : $val;
$out .= '</li>';
}
return $out . '</ul>';
}
$arr = array('firstval','secondval',array('firstval2','secondval2',array('firstval3','secondval3',array('firstval4','secondval4',array('firstval5','secondval5')))));
echo arrToUl($arr);
Output in a jsfiddle.

in view I can fetch all categories:
<?php foreach ($this->parent_categories as $category): ?>
<?php endforeach ?>
Now controller:
$data['parent_categories'] = $this->category_model->get_parent_categories_tree($category);
and finally model category:
//get parent categories tree
public function get_parent_categories_tree($category, $only_visible = true)
{
if (empty($category)) {
return array();
}
//get cached data
$key = "parent_categories_tree_all";
if ($only_visible == true) {
$key = "parent_categories_tree";
}
$key = $key . "_lang_" . $this->selected_lang->id;
$result_cache = get_cached_data($this, $key, "st");
if (!empty($result_cache)) {
if (!empty($result_cache[$category->id])) {
return $result_cache[$category->id];
}
} else {
$result_cache = array();
}
$parent_tree = $category->parent_tree;
$ids = array();
$str_sort = "";
if (!empty($parent_tree)) {
$array = explode(',', $parent_tree);
if (!empty($array)) {
foreach ($array as $item) {
array_push($ids, intval($item));
if ($str_sort == "") {
$str_sort = intval($item);
} else {
$str_sort .= "," . intval($item);
}
}
}
}
if (!in_array($category->id, $ids)) {
array_push($ids, $category->id);
if ($str_sort == "") {
$str_sort = $category->id;
} else {
$str_sort .= "," . $category->id;
}
}
$this->build_query($this->selected_lang->id, true);
$this->db->where_in('categories.id', $ids, FALSE);
if ($only_visible == true) {
$this->db->where('categories.visibility', 1);
}
$this->db->order_by('FIELD(id, ' . $str_sort . ')');
$result = $this->db->get('categories')->result();
$result_cache[$category->id] = $result;
set_cache_data($this, $key, $result_cache, "st");
return $result;
}
but the problem is currently I fetch with this code all categories without limit. How to get first 10 records?
I try:
$result = $this->db->get('categories', 10)->result();
But this not work and still fetch all categories. Can anyone help me resolve this issue? Maybe I do something wrong. Thanks for check.
I have 2 function in a Class, one is a recursive function.
public static function _itemsByParent($categories, $parentId) {
$out = array();
foreach($categories as $category) {
if(empty($category['parent']) && $parentId == 0)
$out[] = $category;
elseif($category['parent'] == $parentId)
$out[] = $category;
}
return (empty($out) ? false : $out);
}
public static function loopOnLevels($input, $parent=0) {
$categories = self::_itemsByParent($input, $parent);
$out = null;
if($categories !== false) {
$i = 0;
$out = '<ul>';
foreach($categories as $category) {
$out .= '<li>'.$category['name_hu'];
$childs = self::loopOnLevels($input, $category['category_id']);
if($childs !== false) {
$out .= $childs;
}
$out .= '</li>';
$i++;
}
$out .= '</ul>';
}
return (empty($out) ? false : $out);
}
I pass a simple array and parent is null at start:
$o = self::loopOnLevels($categoriesTransformed, 0);
My array looks like: http://screencloud.net/v/10sq
....
Why I get 502 Bad Gateway.
Maybe infinite loop? But why?
I have Already Created The Categories in Magento by using the custom script,
but issue is when I again run the same URL my script creates another set of same category. as i want to update the existing category and insert the new categories if exist in the csv.
My csv structure is:

1,COSTUMES,1,ADULTS,1,MENS
1,COSTUMES,1,ADULTS,1,MENS,2,ASIAN

I'm trying to build a tree with the exact specifications of..
This Question
Basically I need to create a tree from a parent - id table structure.
I'm using this function to try to achieve the above;
private static function fetch_recursive($src_arr, $currentid = 0, $parentfound = false, $cats = array())
{
foreach($src_arr as $row)
{
if((!$parentfound && $row['category_id'] == $currentid) || $row['parent_id'] == $currentid)
{
$rowdata = array();
foreach($row as $k => $v)
$rowdata[$k] = $v;
$cats[] = $rowdata;
if($row['parent_id'] == $currentid)
$cats = array_merge($cats, CategoryParentController::fetch_recursive($src_arr, $row['category_id'], true));
}
}
return $cats;
}
But I'm getting an error from PHP :
Maximum function nesting level of 100 reached, aborting!
I'm ordering the db results by parent_id and then by id to help out with the issue but it still persists.
As a side note by table contains ~250 records.
Finally found a solution that fits my needs! Thanks for all the help everyone and also for the constructive criticism :)
Laravel 4 - Eloquent. Infinite children into usable array?
Solution:
<?php
class ItemsHelper {
private $items;
public function __construct($items) {
$this->items = $items;
}
public function htmlList() {
return $this->htmlFromArray($this->itemArray());
}
private function itemArray() {
$result = array();
foreach($this->items as $item) {
if ($item->parent_id == 0) {
$result[$item->name] = $this->itemWithChildren($item);
}
}
return $result;
}
private function childrenOf($item) {
$result = array();
foreach($this->items as $i) {
if ($i->parent_id == $item->id) {
$result[] = $i;
}
}
return $result;

$children = $this->childrenOf($item);
foreach ($children as $child) {
$result[$child->name] = $this->itemWithChildren($child);
}
return $result;

$html .= $this->htmlFromArray($v);
}
$html .= "</ul>";

I have a while loop fetching a row and I'm trying to create a structure so that each row will create 2 links. The first is a German word and the second being an English one. The output I'm getting is repeated as if the row isn't being incremented. I've narrowed it down to this:
PHP:
while ($row = $database->row()->fetch()) {
foreach ($row as $value) {
$this->data .= $value . "!";
}
list($this->pid, $this->german, $this->english) = explode("!", $this->data);
$this->links .= "$this->german<br/>$this->english<br/>";
}
Output:
die Männer
men
die Männer
men
$row = array();
while ($row = $database->row()->fetch()) {
$row[] = $row;
}
foreach ($row as $value)
{
$this->data .= $value . "!";
list($this->pid, $this->german, $this->english) = explode("!", $this->data);
$this->links .= "$this->german<br/>$this->english<br/>";
}
I've solved the problem by looking at the keys and creating variables based on a simple matched string test. If anyone can improve my answer I would like to hear it. Thanks.
PHP:
while ($row = $database->row()->fetch()) {
while(list($key, $value) = each($row)) {
if ($key == "PID") {
$this->pid = $value;
}
if ($key == "german") {
$this->german = $value;
}
if ($key == "english") {
$this->english = $value;
}
}
$this->links .= "$this->german<br/>$this->english<br/>";
}
