<?php $xml = 'connector.php'; echo'
' ; ?> [/code]

Its only define the grid, and call the necesary files and call connetor.php which does the work:

[code]<?php

header(‘Content-Type: text/html; charset=UTF-8’);
error_reporting ( E_ALL ^ E_DEPRECATED);
require_once($_SERVER[‘DOCUMENT_ROOT’].“globalfunctions/globalClasses.php”);
$xml = new SimpleXMLElement(’

Megnevezés
Típus
Hol van
Saját ID
Tipus ID


,#text_filter,#text_filter,#text_filter,

'); $irattar = new indotekDbConnection("irattar");

$sorok = array(
array()

);

$sql1 = mysql_query("
select Megnevezes,tipus_nev, Hol_van, akt_hely.ID,tipus from akt_hely inner join tipus on (akt_hely.Tipus=tipus.ID)

//$szid=mysql_fetch_row($sql1);

$i=0;
while ($i<=$numrows)
{
//if($row[3]=""){
if($sorok[$i][2]==""){
$currSor = $xml->addChild(‘row’);
$currSor->addChild(‘cell’,$sorok[$i][0]);
$currSor->addChild(‘cell’,$sorok[$i][0]);
$currSor->addChild(‘cell’,$sorok[$i][1]);
$currSor->addChild(‘cell’,$sorok[$i][2]);
$currSor->addChild(‘cell’,$sorok[$i][3]);
$currSor->addChild(‘cell’,$sorok[$i][4]);}
else{

}

++$i;
//$currSor->addChild('cell',$row[6]);

}

$irattar->Close();
unset($irattar);
echo $xml->asXML();

?>[/code]

And this fill the grid. In this i want to fill the subgrid too.
Pls help!

Unfortunately it is not available to to load the data to a grid and subgrid from a single xml.
Data for the subgrid can be loaded only from the individual file.
