Using 2 same Recursion to do 2 different things - php

I was trying to show tree data with JQuery expand and collapse.
For example my database
Parent A has AA, AB, AC children
Parent AA has AAA, AAB, AAC
Parent AC has ACA, ACB, ACD
etc.
So I am using Recursion to show all the data from the database.
But I also need to declare the JQuery, so I am using the same Recursion code to generate the script
What I want to ask is, is there any way to use the Recursion one time to generate both things?, the data show inside the <body> tag, and JQuery declare at <head> tag.
Because I feel it will waste the memory to do same thing 2 times.
This is my <body> code
<?
$temp = "";
$parent = "";
$level = 0;
loadFolders($parent, $level, $temp);
function loadFolders($parent, $level, $temp){
$getLevelSql = mysql_query("select * from folders where parent='$parent' and level='$level'");
$level++;
while ($getLevelSqlRow = mysql_fetch_array($getLevelSql)){
$parentID = $getLevelSqlRow['id'];
$child = $getLevelSqlRow['child'];
$checkChild = mysql_query("select * from folders where parent='$parentID' and level='$level' ");
if (mysql_num_rows($checkChild)){
?>
<div class="level1 redFont" id="levelID<?echo $getLevelSqlRow['id'];?>">
<?echo "$child";?>
</div>
<div class="level2" id="childID<?echo $getLevelSqlRow['id'];?>">
<?
loadFolders($parentID, $level, $temp);
?>
</div>
<?
} else {
?>
<div><?echo "$child";?></div>
<?
}
}
}
?>
This is my <head> code
<script>
$(document).ready(function(){
<?
include "config.php";
$temp = "";
$parent = "";
$level = 0;
loadFolder($parent, $level, $temp);
function loadFolder($parent, $level, $temp){
$getLevelSql = mysql_query("select * from folders where parent='$parent' and level='$level'");
$level++;
while ($getLevelSqlRow = mysql_fetch_array($getLevelSql)){
$parentID = $getLevelSqlRow['id'];
$child = $getLevelSqlRow['child'];
$checkChild = mysql_query("select * from folders where parent='$parentID' and level='$level' ");
if (mysql_num_rows($checkChild)){
?>
$("#levelID<?echo $getLevelSqlRow['id'];?>").click(function(){
$("#childID<?echo $getLevelSqlRow['id'];?>").slideToggle("slow");
});
<?
loadFolder($parentID, $level, $temp);
?>
<?
}
}
}
?>
});
</script>
Thanks in advance

I haven't tested this as I haven't got data to do it but basically you really just need to use selectors in your jquery code to find the sub section from any of the click point.
I would nest the child element to make it easier. Something like this:
<?
$temp = "";
$parent = "";
$level = 0;
loadFolders($parent, $level, $temp);
function loadFolders($parent, $level, $temp){
$getLevelSql = mysql_query("select * from folders where parent='$parent' and level='$level'");
$level++;
while ($getLevelSqlRow = mysql_fetch_array($getLevelSql)){
$parentID = $getLevelSqlRow['id'];
$child = $getLevelSqlRow['child'];
$checkChild = mysql_query("select * from folders where parent='$parentID' and level='$level' ");
if (mysql_num_rows($checkChild)){
// ** notice I've added item class and nested the children inside
?>
<div class="level1 redFont item" id="levelID<?echo $getLevelSqlRow['id'];?>">
<?echo "$child";?>
<div class="children" id="childID<?echo $getLevelSqlRow['id'];?>">
</div>
<?
loadFolders($parentID, $level, $temp);
?>
</div>
<?
} else {
?>
<div><?echo "$child";?></div>
<?
}
}
}
?>
Then your jquery becomes something like this:
$(document).ready(function(){
$('div.item').click(function(){
$(this).find('>div.children').slideToggle("slow");
});
});
No need to loop twice and generate a hundred handlers..

Menu created with MySQL only works within website not outside

I hope somebody can help me, because i got an menu that is auto generated via my MySQL db.
Because i got the menu to work inside the website and with that i mean it works with "test.dk/about" but the a href is empty when it's going out of the website like "http://google.com"...
btw it's just a very simple UL LI menu no dropdown or something.
Here is my script
static function build_menu()
{
$result = mysql_query("SELECT * FROM menu");
$menu = array();
while ($row = mysql_fetch_assoc($result)) {
if ($row["is_external"]) {
$url = $row["url"];
} else if (empty($row["is_external"])) {
$url = get_page_url($row["page_id"]);
}
$menu[] = array("name" => $row["name"], "page_id" => $row["page_id"], "is_external" => $row["url"], "url" => $url);
}
return $menu;
}
static function get_page_url($page_id)
{
$result = mysql_query("SELECT view_id FROM page WHERE id = '$page_id'");
$result = mysql_fetch_assoc($result);
$view_id = $result["view_id"];
$result = mysql_query("SELECT listen_path FROM view WHERE id = '$view_id'");
$result = mysql_fetch_assoc($result);
$listen_path = $result["listen_path"];
return $listen_path;
}
static function render()
{
$result = mysql_query("SELECT * FROM menu"); ?>
<div class="menu">
<ul><?php while ($item = mysql_fetch_assoc($result)) { ?>
<li><?php echo $item["name"] ?>
</li> <?php } ?></ul></div><?php
}
How can i fix it, so it works both internal and external?
<div class="menu"> <ul> <li>Homepage</li> <li>About</li> <li>Develop</li> <li>Support</li>
This should be <li>Support</li>; </ul> </div>
You only check for an external link in the function build_menu(), but this function isn't called anywhere from your render() function.
The render() function only calls get_page_url() which doesn't distinguish between internal and external links.
Href parameter of external URL must start with protocol declaration, so with "http://" in your case.
So change your code in condition inside the function "build_menu", if the URL is external, add "http://" to it, something like this:
$url = 'http://'.$row["url"];
I got it work after a while!
I simply just created an If else statement in the render function
static function render(){
$menu_items = self::get();
?><div class="menu"><ul><?php while ($item = mysql_fetch_assoc($menu_items)) { ?>
<li><a href="<?php
if(empty($item["is_external"]))
{
echo self::get_page_url($item["page_id"]);
}
else if($item["is_external"] = 1)
{
echo $item["url"];
}
?>"><?php echo $item["name"] ?></a>
</li> <?php } ?></ul></div><?php
}

OOP PHP MySQL return multiple rows and variable

I am new w/ OPP and big pardon if my question maybe too simple :)
Table category, navigation, etc contains multiple rows (category : samsung, apple, etc; and navigation : about us, terms, etc) and both stand as Menu in all pages (home, product,etc)
My old php code and work good is below
<div id="categories">
<ul>
<?
$mydbcategories = new myDBC();
$resultcategories = $mydbcategories->runQuery("SELECT * FROM `category`");
while ($rowcategories = $mydbcategories->runFetchArray($resultcategories)) {
echo '<li>'.$rowcategories[title].'</li>';
}
?>
</ul>
</div>
<div id="navigation">
<ul>
<?
$mydbnavigation = new myDBC();
$resultnavigation = $mydbnavigation->runQuery("SELECT * FROM `navigation`");
while ($rownavigation = $mydbnavigation->runFetchArray($resultnavigation)) { echo '<li>'.$rownavigation [title].'</li>';
}
?>
</ul>
</div>
I would like to implement OOP PHP and create class then store in classes.php
<?
class Menu{
var $title;
var $url;
function setMenu($db){
$mydbMenu= new myDBC();
$resultmenu = $mydbMenu->runQuery("SELECT * FROM `$db`");
$resultmenurows = mysqli_num_rows($resultmenu);
while ($rowmenu = $mydbMenu->runFetchArray($resultmenu)){
$this->title = $rowmenu[title];
$this->url = $rowmenu[url];
}
}
function getTitle() { return $this->title;}
function getUrl() { return $this->url;}
}
?>
Then i'm edit my old code with new one below;
<div id="categories">
<ul>
<?
$catmenu = new Menu();
while ($catmenu ->setMenu('category')) {
echo '<li>'.$catmenu->getTitle().'</li>';
}
?>
</ul>
</div>
<div id="navigation">
<ul>
<?
$navmenu = new Menu();
while ($navmenu ->setMenu('category')) {
echo '<li>'.$navmenu ->getTitle().'</li>';
}
?>
</ul>
</div>
I tested and error maybe because there are multiple rows (from table) in the setMenu func.
How can i return this multiple rows ? should i use array ?
Please help me to solve this and any reply really very appreciate
You are coding PHP4 OOP style, this is very outdated. Don't use var, use public, protected, private.
$this->title = $rowmenu[title] in here, title is used as a constant (no quotes), proper: $this->title = $rowmenu['title'], same with $rowcategories[title]
"SELECT * FROM $db" is this correct? Or do you mean SELECT * FROM menu WHERE xxx='" . $db . "', do you catch errors if the lookup fails?
You should also look at PHP design patterns and code style to improve!
Try following PHP code
<?
class Menu {
var $title;
var $url;
function setMenu($db) {
$mydbMenu = new myDBC();
$resultmenu = $mydbMenu->runQuery("SELECT * FROM `$db`");
$resultmenurows = mysqli_num_rows($resultmenu);
$this->title = array();
$this->url = array();
while ($rowmenu = $mydbMenu->runFetchArray($resultmenu)) {
$this->title[] = $rowmenu['title'];
$this->url[] = $rowmenu['url'];
}
}
function getTitle($ind) {
return $this->title[$ind];
}
function getUrl($ind) {
return $this->url[$ind];
}
}
?>
And HTML
<div id="categories">
<ul>
<?
$catmenu = new Menu();
$catmenu->setMenu('category');
$i = 0;
while ($catmenu->getTitle($i)) {
echo '<li>' . $catmenu->getTitle($i) . '</li>';
$i++;
}
?>
</ul>
</div>
<div id="navigation">
<ul>
<?
$navmenu = new Menu();
$navmenu->setMenu('navigation');
while ($navmenu->getTitle($i)) {
echo '<li>' . $navmenu->getTitle($i) . '</li>';
$i++;
}
?>
</ul>
</div>

Have a php class return array values and keep looping until end

I'm trying to create a website that allows for easy theme adding/manipulation like wordpress and other CMS systems do. To do this I'd like to make it so the theme file that delivers the content uses as little php code as possible. At the moment this is the (extremely simplified) class
class getparents {
var $parentsarray;
function get_parents() {
$this->parentsarray = array();
$this->parentsarray[] = array('Parent0',3,1);
$this->parentsarray[] = array('Parent1',8,2);
$this->parentsarray[] = array('Parent2',2,3);
return $this->parentsarray;
}
}
And retrieving it like this:
$parents = new getparents();
?><table><?php
foreach($parents->get_parents() as $rowtable)
{
echo "<tr><td>$rowtable[0] has category ID $rowtable[1] and is on level $rowtable[2] </td></tr>";
}
?></table><?php
But I want to make the retrieving more like this:
<table>
<tr><td><?php echo $cat_title; ?> has category ID <?php echo $cat_id; ?> and is on level <?php echo $cat_level; ?> </td></tr>
</table>
Which basically mean the class would just return the value in an understandable way and automatically keep on looping without the user having to add *foreach($parents->get_parents() as $rowtable)* or something similar in their theme file.
Here's an example wordpress page to (hopefully) illustrate what I mean. This page retrieves all posts for the current wordpress category which is what I'm trying to mimic in my script, but instead of retrieving posts I want to retrieve the category's parents, but I don't think it's important to explain that in detail.
<?php
/**
* The template for displaying Category Archive pages.
*
* #package WordPress
* #subpackage Twenty_Ten
* #since Twenty Ten 1.0
*/
get_header(); ?>
<div id="container">
<div id="content" role="main">
<h1 class="page-title"><?php
printf( __( 'Category Archives: %s', 'twentyten' ), '<span>' . single_cat_title( '', false ) . '</span>' );
?></h1>
<?php
$category_description = category_description();
if ( ! empty( $category_description ) )
echo '<div class="archive-meta">' . $category_description . '</div>';
/* Run the loop for the category page to output the posts.
* If you want to overload this in a child theme then include a file
* called loop-category.php and that will be used instead.
*/
get_template_part( 'loop', 'category' );
?>
</div><!-- #content -->
</div><!-- #container -->
<?php get_sidebar(); ?>
<?php get_footer(); ?>
Note: My actual question doesn't have anything to do with wordpress at all so I didn't add it as a tag.
UPDATE: I think my question may have been unclear. Here's a messy example (that works nevertheless)
index.php
<?php
include_once("class.php");
include_once("config.php");
if(isset($_GET['catid']))
{
$getproducts = new getproducts($_GET['catid']);
$catproductsarray = $getproducts->getarray();
$indexxx = 0;
foreach($catproductsarray as $rowtable)
{
include("templates/$template/all_products.php");
$indexxx++;
}
}
class.php
class getproducts {
var $thearrayset = array();
public function __construct($indexx) {
$this->thearrayset = $this->makearray($indexx);
}
public function get_id($indexxx) {
echo $this->thearrayset[$indexxx]['id'];
}
public function get_catID($indexxx) {
echo $this->thearrayset[$indexxx]['catID'];
}
public function get_product($indexxx) {
echo $this->thearrayset[$indexxx]['name'];
}
public function makearray($indexx) {
$thearray = array();
if(!is_numeric($indexx)){ die("That's not a number, catid."); };
$resulttable = mysql_query("SELECT * FROM products WHERE catID=$indexx");
while($rowtable = mysql_fetch_array($resulttable)){
$thearray[] = $rowtable;
}
return $thearray;
}
public function getarray() {
return $this->thearrayset;
}
}
templates/default/all_products.php
<!-- The below code will repeat itself for every product found -->
<table>
<tr><td><?php $getproducts->get_id($indexxx); ?> </td><td> <?php $getproducts->get_catID($indexxx); ?> </td><td> <?php $getproducts->get_product($indexxx); ?> </td></tr>
</table>
So basically, index.php gets loaded by user after which the amount of products in mysql database is taken from the class. For every product, all_products.php gets called with $indexxx upped by one.
Now the only thing the user has to do is edit the HTML all_products.php and the products will all be displayed differently. This is what I'm going for, but in a clean, responsible way. Not like this, this is a mess!
UPDATE2: I found a better way to do it, but added it as an answer. Seemed more fitting and pevents this question from getting any longer/messyer than it already is.
Ok I'm getting a little bit closer to what I want, so I'm adding this as an answer.
The template:
<?php include("templates/$template/header.php"); ?>
<!-- [product][description][maxchars=##80##][append=##...##] -->
<!-- [categories][parents][name][append= ->] --><!-- maxchars=false means dont cut description -->
<!-- [categories][children][prepend=nothing] --><!-- prepend=nothing means no prepend -->
<div id="middle-left-section">
<table>
{start-loop-categories-parents}
<tr><td><!-- [categories][parents][name] --></td><td>
{end-loop-categories-parents}
</table>
<table>
<tr><td><!-- [categories][current] --></tr></td>
{start-loop-categories}
<tr><td> <!-- [categories][children] --></td><td>
{end-loop-categories}
</table>
</div>
<div id="middle-right-section">
<table id="hor-minimalist-a">
<thead>
<th scope="col"> </th>
<th scope="col">Name</th>
<th scope="col" width="200px">Description</th>
<th scope="col">Price</th>
</thead>
<tbody>
{start-loop-product}
<tr><td><img src="fotos/<!-- [product][thumb] -->"></img></td><td><!-- [product][name] --></td><td><!-- [product][description] --></td><td><!-- [product][price] --></td></tr>
{end-loop-product}
</tbody>
</table>
</div>
<div style="clear: both;"/>
</div>

The php requested by the website visitor, which will call the current template's all_products.php
include_once("class.php");
$listproducts = new listproducts();
include_once($listproducts->listproduct());
So what this really is, is just string_replacing the HTML comments in the template file with the PHP result I want there. If it's a loop, I Single out the html code I want to loop -> Start an empty string variable -> Repeat that HTML code, appending each loop to the string variable -> Use this string variable to replace the HTML comment
The newly built page is then written to an actual file, which is then included.
I'm completely new to OOP, so this is pretty elaborate stuff for me. I'd like to know if this is a good way to tackle my problem. And also, is it possible to prevent having to rewrite that entire class for every page?
As an example, if I also wanted to build a guestbook I'd like to rewrite the class in a way that it can accept passed variables and build the page from there, rather than pre-setting alot of stuff limiting it to one 'task' such as retrieving products. But before I go any further I'd like to know if this is an a-okay way to do this.

Help with my funky PHP loop

Ok so i have this page and when viewed in firefox the proper results show up but when i look at it in chrome or safari it is way off. Could it be the funky php loop that i am using that makes it off in the browsers..Here is my code
I am generating a left and right array..seems like a hack to me
$left = array();
$right = array();
$finaltot=0.00;
for($i=0;$i<count($steps);$i++)
{
$sql="SELECT * FROM configure_system WHERE EstimateID='".$_SESSION['ESTQUOTE']."' AND StepID=".($i+1) ;
$expstep=ExecuteGetRows($sql);
if ($i % 2 == 0) {
$sql="SELECT SUM(TotalPrice) AS TOT FROM configure_system WHERE EstimateID='".$_SESSION['ESTQUOTE']."' AND StepID=".($i+1);
$tots=ExecuteGetRows($sql);
$left["Step"][$i][] = $steps[$i];
$left["expstep"][$i][] = $expstep;
$left["final_total"][$i][] = $tots[0]['TOT'];
$finaltot+=$tots[0]['TOT'];
} else {
$sql="SELECT SUM(TotalPrice) AS TOT FROM configure_system WHERE EstimateID='".$_SESSION['ESTQUOTE']."' AND StepID=".($i+1);
$tots=ExecuteGetRows($sql);
$right["Step"][$i][] = $steps[$i];
$right["expstep"][$i][] = $expstep;
$left["final_total"][$i][] = $tots[0]['TOT'];
$finaltot+=$tots[0]['TOT'];
}
then since the left array only has 0,2,4,6,8,10
and right has 1,3,5,7,9,11
so my loops are like this
<?php for($i=0;$i<count($left['Step']) * 2;$i++) { ?>
<?php $i++; ?>
<?php } ?>
<?php for($i=1;$i<count($right['Step'])* 2;$i++) { ?>
<?php $i++; ?>
<?php } ?>
So as you can see the code is a bit off and i think that maybe the problem with why safari and chrome are off...any suggestions
Why do not use foreach instead?
foreach ($right['Step'] as $i => $val) {
// ...
}
Also you could get the same results with only one query:
SELECT SUM(TotalPrice) AS TOT
FROM configure_system
WHERE EstimateID='".$_SESSION['ESTQUOTE']."'
GROUP BY StepID

How to create a nested menu from MySQL with PHP?

I need to create a menu with PHP from a MySQL database.
Table called categories has id, name, parent_id, shortdesc, etc.
The output need to have parent list and children list under the partent list as follows.
If you can show me codes or website, I will appreciate it.
<ul id="catmenu">
<li class="menulist">Cars
<ul>
<li>Ford</li>
<li>Honda</li>
<li>Toyota</li>
</ul>
</li>
<li class="menulist">Food
<ul>
<li>Pasta</li>
<li>Pizza</li>
...
</ul>
</li>
...
...
</ul>
This is specifically for two levels deep. Recommended approach should it be more is to use an optimized table structure for traversal, like http://articles.sitepoint.com/article/hierarchical-data-database/2 (pointed out elsewhere) or to pull the data you need and push it into a dictionary (associative array) and query it that way.
<?php
$query = <<<EOT
SELECT
parent.name as parent_name,
child.name as child_name,
FROM
items child
INNER JOIN
items parent
ON
child.parent_id = parent.id
ORDER BY
parent.name
EOT;
$result = mysql_query($query) or die('Failure!');
echo "<ul id=\"catmenu\">";
$last_parent = '';
while($row = mysql_fetch_array($result)){
// If this is a new category, start a new one
if($last_parent != $row['parent_name']){
// Unless this is the first item, close the last category
if($last_parent != ''){
echo "</ul></li>";
}
$last_parent = $row['parent_name'];
echo "<li class=\"menulist\">{$row['parent_name']}<ul>";
}
echo "<li>{$row['child_name']}</li>";
}
// If we actually had items, close the "category"
if($last_parent != ''){
echo "</ul></li>";
}
echo "</ul>";
?>
If you have only two levels then, you could just display them :
echo '<ul id="catmenu">';
foreach($menu as $element) {
echo '<li><ul class="menulist">';
foreach($element['submenu'] as $submenu) {
echo '<li>' . $submenu['name'] . '</li>';
}
echo '</ul></li>';
}
echo '</ul>
If you have an undefined number of submenus however you should use a Recursive Function.
function menu($item) {
$ret = '<li>' . $item['name'];
if (!empty($item['submenu'])) {
foreach($item['submenu'] as $submenu) {
$ret .= menu($submenu);
}
}
return $ret;
}
echo menu($menu);
So every of your subcategories, whatever their number is will be displayed.
You make database like this.
ID NAME PARENT
0 Cars -1
1 Foods -1
2 Ford 0
3 Honda 0
4 Toyota 0
5 Pasta 1
6 Pizza 1
...
You query them all up and put it in an array.
$Menus = array();
// In a read MySQL loop
$Menus[$i]['ID']
$Menus[$i]['NAME']
$Menus[$i]['PARENT']
// Sorry, lazy to write. I think you know what I mean.
Then you loop all menu looking for PARENT == -1. Generate all UL and IL then sub it with another nested menu.
You can simply create a function like this.
var $MenuLevelClass = array("menulist");
function CreateMenu($Menus, $Tab = 0, $Parent = -1, $Level = 0) {
global $MenuLevelClass;
$CatClass = ($Level != 0) ? '' : ' class="catmenu"';
$MenuClass = $MenuLevelClass[$Level];
if ($MenuClass != '')
$MenuClass = ' class="'.$MenuClass.'"';
$TabCount = $Level + $Tab;
$TabUL = "";
for ($t = 0; $t < $TabCount; $t++)
$TabUL = $TabUL."\t";
$TabLI = $TabUL."\t";
?>
<?=$TabUL?><ul<?=$CatClass?>>
<?php
$MenuCount = count($Menus);
for ($m = 0; $m < $MenuCount; $m++) {
$Menu = $Menu[$m];
$ID = $Menu['ID'];
if ($ID != $Parent)
continue;
?>
<?=$TabLI?><li<?=$MenuClass?>><?=$Menu['Name']?><?=CreateMenu($Menus, $Tab + 1, $ID, $Level + 1)?></li>
<?php
?>
<?=$TabUL?></ul>
<?php
}
}
And to use it just run 'CreateMenu($Menus);' or 'CreateMenu($Menus, $PrefixTabCount);'.
CreateMenu will recursively create the nested menu for you.
I have not test it so you may have to adjust it.
Hope this helps.
