                mostrarDetallesCuidadano(clv);
                initMapa();

            }
        });
        $("#listaRedCuidadana").jqGrid('navGrid',"#pager",{edit:false,add:false,del:false});

and my .php file

<?php
require_once '../../sesion/model/clsSesion.php';

if ( stristr($_SERVER["HTTP_ACCEPT"],"application/xhtml+xml") ) {

}
if(isset($_REQUEST['nodeid'])==FALSE) {
    $node =0;
}
else{
    $node = (integer)$_REQUEST["nodeid"];
}
$clsJqGrid = new redCuidadana();
$et = ">";
echo "<?xml version='1.0' encoding='utf-8'?$et\n";
echo "<rows>";
echo "<page>1</page>";
echo "<total>1</total>";
echo "<records>1</records>";

if($node >0) { //check to see which node to load
   $wh = 'parent_id='.$node; // parents
   //$n_lvl = $n_lvl+1; // we should ouput next level
} else {
   //$wh = 'ISNULL(parent_id)'; 
   $wh ='parent_id=0';// roots
}
$mostrarRegistros= $clsJqGrid->mostrarRegistros($wh);
foreach ($mostrarRegistros as $row){
   echo "<row>";

Answer 1

1. try to simply echo sample xml from php without any logic performed and see if it is received by JS script;

2. as it was said, try to access PHP script directly in your browser and see if it returns valid result;

3. try to debug your code in chrome (not only in ff:firebug), these are both great tools and sometimes chrome can show what ff missed (and vise versa).

These steps will help you to isolate and find problem. If you’ll have all these bullets above checked and problem still there – provide results in topic, so we’ll have oportunity to help you.

Cheers and good luck 😉
