Hey guys i need to create a genealogy tree view in PHP and i have no idea on how to get started ... Is there existing class's for that out there? Any recomandations on the "how to"? Maby flash/xml is better? ... I am lost ...

Hi guys

I need help writing a php script

I have a table 'categories'

with fields
'id' 'cat_name' 'parent_id'

the 'parent_id' is just an the id field..

I want to create a way to have unlimited sub categories

so I can have

categorie -> sub-categories
categories  -> sub-categories  -> sub-categories
categories -> products

hi all.

I am working on a MLM project in which i have more than 30,000 members followed by the root member,i have to store member automatically in binary tree form like

1 is root
2 is child of 1
3 is child of 1

Then 4 is child of 2
5 is child of 2

and so on ......

i have to design database for that.

please help

Hi,

I wrote a piece of code for doing a recursive printing of all the leaf nodes.

But it is not moving beyond one or two levels.

Here is the code:

$root = array(
"paa" => array (
"adi1" => array (
"cir1" => array (
"aka",
"ra", "vinodh","dkido"
),

"cir2" => array (
   "muta",
"la"
),

"cir3" => array (
"ezut",
"telAm"
),

"cir4" => array (
"ati"
)
),

"adi2" => array (

"cir1" => array (
"paka",
"vaV"
),

"cir2" => array (
"mutaR",
"RE"
),

"cir3" => array (
"ula",
"ku"
)
)
                )
            );

function traverse($ar)
{

foreach($ar as $key=>$value)

          {

echo "inside loop of ".$key."<br/>";

if(is_array($value))
{
    return traverse($value);
}

else

{
     echo $key."==>".$value."<br/>";
}

   }


}

traverse($root);


The output I get is:

inside loop of paa
inside loop of adi1
inside loop of cir1
inside loop of 0
0==>aka
inside loop of 1
1==>ra
inside loop of 2
2==>vinodh
inside loop of 3
3==>dkido

It does not seem to visit the other nodes.

Anything I missed here ?

Can somebody please have a look at this.  The Problem I am having is that only 1 entry for each month goes into the tree and for the life of me I can't figure out why.

Code: [Select]
$queryyp = "SELECT YEAR(date) as year, MONTHNAME(date) as month, title FROM monsterpost ORDER BY date DESC"; // query to get the rows you want in the order that you want them, with the year and monthname specifically selected as well
$resultyp = mysql_query($queryyp);
$last_heading = null; // remember the last heading (initialize to null)
while($rowyp = mysql_fetch_assoc($resultyp)){
$new_heading = $rowyp['year']; // get the column in the data that represents the heading
$new_subheading = $rowyp['month']; // get the column in the data that represents the subheading
if($last_heading != $new_heading){
// heading changed or is the first one
$last_heading = $new_heading; // remember the new heading
$last_subheading = null; // (re)initialize the subheading
// start a new section, output the heading here...
echo "<ol class=\"tree\"><li><label for=\"folder1\">{$rowyp['year']}</label> <input type=\"checkbox\" id=\"folder1\" /></li></ol>";
}
// subheading under each heading
if($last_subheading != $new_subheading){
// subheading changed or is the first one
$last_subheading = $new_subheading; // remember the new subheading
// start a new section, output the subheading here...
    echo "<ol><li><label for=\"subfolder1\">{$rowyp['month']}</label> <input type=\"checkbox\" id=\"subfolder1\" />";

}
// output each piece of data under a heading here...
echo "<ol><li class=\"file\">{$rowyp['title']}</li></ol></li></ol></li></ol>";
}

Hello everybody,

i am working on n level category tree structure, for your information the category tree structure image is attached with this post.

Let's consider, each of the category have hundreds( n level ) of category in each, i want to traverse each category without using recursive functions, reason being recursive functions are very slow,  is there any way to do this??

Thanks,
phpeid

Hey guys, I have a bunch of categories and products in a tree format. For several reasons I need to restructure them from the tree format into a flattened format.

I have 2 arrays, one full of categories, the other products. Each category and product has an ID, and a reference to it's parent's ID. The top level categories reference to 0.

What I need is to have the categories output like thus:

Top Level Categories:
  Category 1
  Category 2

Category 1
  Sub category 1
  Sub category 2

Category 2
  Sub category 3
  Sub category 4

Sub category 1
  Product 1
  Product 2

Sub category 2
  Product 3
  Product 4

Sub category 3
  Product 5
  Product 6

Sub category 4
  Product 7
  Product 8

There could be an unlimited number of sub categories within categories before we get to products, so this needs to be done through a function, however I cannot for the life of me think how to do this. Initially I thought about using 2 arrays, a buffer of categories outputted, and a queue of categories to be outputted, but quickly realised that when I go more than 2 layers deep I can't keep track of the queue's properly.

Hey guys,
i am a college student and working on a project of mlm ad want to display the binary income tree,and also calculate the income that is given to each node.
Please see the attachments for the binary tree structure and database table structure.
Thanks.

[attachment deleted by admin]

This is my first try to display binary tree so please go easy on me.
I am trying to display binary tree using array. The values are stored in mysql.

Structure of mysql-
Code: [Select]
CREATE TABLE IF NOT EXISTS `tree` (
  `parent` int(7) NOT NULL,
  `rchild` int(7) NOT NULL,
  `lchild` int(7) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

Display should look like
Code: [Select]
                    1
              ______|______
             |             |
             2             3
                     ______|______
                    |             |
                    4              5   


My Code till now-
Code: [Select]
<?php
 include 'connection.php';
 $rsearch = "SELECT rchild FROM tree WHERE parent='".$parent."'";
 $lsearch = "SELECT lchild FROM tree WHERE parent='".$parent."'";
    
  $rexec = mysql_query($rsearch);
  $lexec = mysql_query($lsearch);
  
  while($rrow = mysql_fetch_assoc($rexec)) // Putting right branch in an array first
{
    $rtree[$i][0] = $rrow['parent'] ; 
    $rtree[$i][1] = $rrow['lchild'] ;
    $rtree[$i][2] = $rrow['rchild'] ;
    $i++;
}
while($lrow = mysql_fetch_assoc($lexec)) // Putting left branch in an array 
{
    $ltree[$j][0] = $lrow['parent'] ; 
    $ltree[$j][1] = $lrow['lchild'] ;
    $ltree[$j][2] = $lrow['rchild'] ;
    $j++;
}

function displaytree($parent,$array)
{
   // Im stuck here. Can someone please help me with it
}
?>
I am stuck at displaying the tree function. Can someone please point me in the right direction ?

I am trying to display binary tree  level wise. Breadth-first tree traversal can be used in it.Can anyone point me towards its logic or point me towards a good tutorial.

I am trying to count left node of a binary tree.I made a function but my result is always 3 .

Code:-

Code: [Select]
<?php
  include'config.php';  // Connect database

  function leftcount($node)   //Function to calculate leftcount
  {
    $sql = "SELECT lchild,rchild FROM tree WHERE parent = '$node'";
    $execsql = mysql_query($sql);
    $array = mysql_fetch_array($execsql);
    
    if(!empty($array['lchild']))
    {
      $count++;
      leftcount($array['lchild']);  
    } 
    if(!empty($array['rchild']))
    {
       $count++;
       leftcount($array['rchild']); 
    }
    
    $totalcount = 1 + $count;
    return $totalcount;
    
  }
  
  $parent = "2";
  $left = leftcount($parent);
  echo $left;
  
?>
Can someone please point the error in my logic ? I searched google but i only got scripts with classes and i don't want to use classes.

Hello my good people   I'm doing a content manager system in PHP and mySQLi, following a serie of video tutorials. But in my project I am using a tree menu. In the front office all works smoothly (the tree menu displays all results - menu and submenus - and each button carries the information of the respective page).

Evening everyone and Merry X-Mas (Happy Holidays) or whatever fits you best....   I have been trying over and over for about 12 hours to figure out how to get data from a specific JSON response and assign the specific values to a new array key/value pair. The various ways I have tried to figure this out are  numerous so i'm going to avoid the runnig list of "I trieid this...and this...and this... etc etc." just understand I have reached a dead end point where I need help badly.   Here is what our end goal is:   "The company" is a "service industry" provider (plumbing, electrical etc. etc.) who wants to dispatch its technicians to new jobs based on which technician has the shortest travel time from any existing address where they already have a scheduled appointment that day and has available time in there schedule. Thus the dispatching system when a new service call is entered is going to give "recommended" technicians (up to 4) to be assigned the new service call based on the above mentioned criteria. (Efficient routing to save company gas cost)   1.) We have a "New service" street address assigned to the $to variable: $to = "4813 River Basin Dr S, Jacksonville FL 32207";
    2.) We will have "records" array which containes a series of records, each record consists of a ticket# a technician id# and a street address: $records = array(
array("DV1012","30453423","9890 Hutchinson Park Dr Jacksonville, FL 32225"),
array("DB3434","30404041","821 Orange Ave Crescent City, FL 32112"),
array("DB3434","30605060","1972 Wells Road, Orange Park FL 32073"),
array("DB4578","30605060","2 Independent Drive, Jacksonville FL 32202"),
array("DB7841","30605060","5000 Norwood Avenue, Jacksonville FL 32208"),
array("DB3235","30605060","9501 Arlington Expressway, Jacksonville FL 32225"),
array("DB7894","30605060","Massey Avenue, Jacksonville, FL 32227"),
array("DB2020","30121212","11200 Central Pkwy Jacksonville, FL 32224")
                );   3.) We are going to prepare the records array for submission to Google's Distance Matrix API by URL encoding each array value into a single variable and then submit it:   foreach ($records as $key => $value) {$from = $from.urlencode($value[2])."|";} $to = urlencode($to);
$data = file_get_contents("//maps.googleapis.com/maps/api/distancematrix/json?origins=$from&destinations=$to&language=en-EN&units=imperial&mode=driving&sensor=false");
$res=json_decode($data) or die("Error: Cannot read object");
  You may look at the ACTUAL live Google response from this he http://tiny.cc/i6eerx  (We have applied <pre> and var_dump($res) to the output)   We are looking to get the following information back: The distance and travel time between the "New Service" address ($to) and each of the address' in the $records array ($from), now once that information is returned from Google (JSON response) we need to parse the response and narrow it down to 4 or less (Based on the 4 lowest drive times) to form a new array which ends like this:   $results = array(
array("DV1012","30453423","2.3 Miles","8 mins"),
array("DB3434","30404041","2.8 Miles","9 mins"),
array("DB3434","30605060","4.6 Miles","13.8 mins"),
array("DB4578","30605060","5.7 Miles","15.2 min")
                ); OUR PROBLEM: Everything up until the the Google API response is fine, but iterating over the multidimensional arrays within multidimensional arrays of the JSON response is just not coming together in my head (or 2 dozen code attempts). I am able to ECHO an individual value like ( echo $res->rows[0]->elements[0]->distance->text; ) but this has no value for the end result i need to get to. My last thoughts and efforts was that that I was going to have to embed foreach statements within foreach statements to drill down through the various arrays but that hasn't worked very well and it seems like it shouldn't be how it has to be done. I would appreciate any help in showing me how the iteration code should be written and any explanation about the code so i can wrap my head around it.

hello !

I need a PHP script for my site ;

I need a script like this for my family tree site ;







Thank  you!
