jQuery Grid Plugin - jqGrid

this the last part of expamle.php:

<?php

....

...

// the actual query for the grid data
$SQL = "SELECT * , date_format(data_fattura, '%d-%m-%Y') AS data_fattura_l FROM articoli ORDER BY $sidx $sord LIMIT $start , $limit";
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error());
 
$responce->page = $page;
$responce->total = $total_pages;
$responce->records = $count;
$responce->userdata['pie'] = $piesum;
$i=0;

while($row = mysql_fetch_array($result,MYSQL_ASSOC))
{
    $responce->rows[$i]['id']=$row[id];
    $responce->rows[$i]['cell']=array("$row[codice] - $row[descrizione]",
                                      $row[prezzoie],
                                      $row[prezzoiev],
                                      $row[fattura_vendita],
                                      $row[id_pagato],
                                      $row[id_incassato],
                                      $row[data_fattura_l],
                                      $row[note]);
    $i++;
}
echo json_encode($responce);

?>

It doesn't work... sorry but I'm a news user can you explain me?

thanks a lot!

This is the script in the file html:

<script type="text/javascript">
jQuery(document).ready(function(){
  jQuery("#list").jqGrid({
    url:'example.php',
    datatype: 'json',
    mtype: 'GET',
    colNames: ['cod - desc', 'pie', 'p.v. ie', 'fattura vendita', 'p', 'i', 'data fattura', 'note'],
    colModel :[
      {name:'cod', index:'cod', sortable: false, resizable: false},
      {name:'pie', index:'pie', sortable: false, resizable: false},
      {name:'pvie', index:'pvie', sortable: false, resizable: false},
      {name:'fattura_vendita', index:'fattura_vendita', sortable: true, resizable: false},
      {name:'p', index:'p', sortable: false, resizable: false},
      {name:'v', index:'v', sortable: false, resizable: false},
      {name:'data_fattura', index:'data_fattura', sortable: true, resizable: false},
      {name:'note', index:'note', sortable: false, resizable: false}
    ],

    footerrow: true,
    userDataOnFooter: true,
    pager: '#pager',
    rowNum:10,
    rowList:[10,20,30],
    sortname: 'data_fattura',
    sortorder: 'desc',
    viewrecords: true,
    autowidth: true,
    height: '100%',
    caption: 'La mia tabella'
  });
});
jQuery("#list").footerData('set',{cod:'Total',pie:sum});
</script>

and this is the file example.php:

<?php
//include the information needed for the connection to MySQL data base server.
// we store here username, database and password
include("_conn.db.inc.php");
 
// 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;
 
// calculate the number of rows for the query. We need this for paging the result
$sql="SELECT COUNT(*) AS count FROM articoli";
$result = mysql_query($sql,$db) or die(mysql_error());
$row = mysql_fetch_array($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 data
$SQL = "SELECT * , date_format(data_fattura, '%d-%m-%Y') AS data_fattura_l FROM articoli ORDER BY $sidx $sord LIMIT $start , $limit";
$result = mysql_query( $SQL ) or die("Couldn't execute query.".mysql_error());
 
$responce->page = $page;
$responce->total = $total_pages;
$responce->records = $count;
$responce->userdata['pie'] = $piesum;
$i=0;

while($row = mysql_fetch_array($result,MYSQL_ASSOC))
{
    $responce->rows[$i]['id']=$row[id];
    $responce->rows[$i]['cell']=array("$row[codice] - $row[descrizione]",
                                      $row[prezzoie],
                                      $row[prezzoiev],
                                      $row[fattura_vendita],
                                      $row[id_pagato],
                                      $row[id_incassato],
                                      $row[data_fattura_l],
                                      $row[note]);
    $i++;
}
echo json_encode($responce);
?>

but the total isn't print...
Where is the error?

Thanks for all !
