jqgrid

#1
[eluser]Unknown[/eluser]
Hello trying to make a basic exercise with jqGrid not get to show me the data, ie, shows me what is the design but not the data.
I have tried in the file do a print_r jqgrid.php m but not display anything.
GRATEFUL who could help me
My code is as follows:

vista - contenido3.php
[code]
<html>
<head>
<title>Principal</title>
</head>
<body>
<h1>CLientes</h1>

<table id="list">
</table>
<div id="pager">
<p>Holaaaa</p>
</div>
&lt;/body&gt;
&lt;/html&gt;

jqgrid.php

&lt;?php
//include the information needed for the connection to MySQL data base server.
// we store here username, database and password

// to the url parameter are added 4 parameters as described in colModel
// we should get these parameters to construct the needed query
// Since we specify in the options of the grid that we will use a GET method
// we should use the appropriate command to obtain the parameters.
// In our case this is $_GET. If we specify that we want to use post
// we should use $_POST. Maybe the better way is to use $_REQUEST, which
// contain both the GET and POST variables. For more information refer to php documentation.
// Get the requested page. By default grid sets this to 1.
$page = $_GET['page'];

// get how many rows we want to have into the grid - rowNum parameter in the grid
$limit = $_GET['rows'];

// get index row - i.e. user click to sort. At first time sortname parameter -
// after that the index from colModel
$sidx = $_GET['sidx'];

// sorting order - at first time sortorder
$sord = $_GET['sord'];

// if we not pass at first time index use the first column for the index or what you want
if(!$sidx) $sidx =1;

$db = mysql_connect('localhost', 'root', 'root') or die("Connection Error: " . mysql_error());

// select the database
mysql_select_db('optinet') or die("Error connecting to db.");

// calculate the number of rows for the query. We need this for paging the result
$result = mysql_query("SELECT COUNT(*) AS count FROM clientes");
$row = mysql_fetch_array($result,MYSQL_ASSOC);
$count = $row['count'];

// calculate the total pages for the query
if( $count > 0 && $limit > 0) {
$total_pages = ceil($count/$limit);
} else {
$total_pages = 0;
}

// if for some reasons the requested page is greater than the total
// set the requested page to total page
if ($page > $total_pages) $page=$total_pages;

// calculate the starting position of the rows
$start = $limit*$page - $limit;

// if for some reasons start position is negative set it to 0
// typical case is that the user type 0 for the requested page
if($start <0) $start = 0;

// the actual query for the grid dat
$SQL = "SELECT * FROM clientes";
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error());
print_r($result);

// we should set the appropriate header information. Do not forget this.
header("Content-type: text/xml;charset=utf-8");

$s = "&lt;?xml version='1.0' encoding='utf-8'?&gt;";
$s .= "<rows>";
$s .= "<page>".$page."</page>";
$s .= "<total>".$total_pages."</total>";
$s .= "<records>".$count."</records>";

// be sure to put text data in CDATA
while($row = mysql_fetch_array($result,MYSQL_ASSOC)) {
$s .= "<row id='". $row['DNI']."'>";
$s .= "<cell>". $row['Nombre']."</cell>";
$s .= "</row>";
}
$s .= "</rows>";

echo $s;
?&gt;
