How do i correct jqgrid footer information? - cakephp

Question

I am using jqgrid in one of my application.
Right now i am facing a strange problem and do not know how to rectify it?
Actually in one of the reports (having multiple link) jqgrid is showing wrong footer information that is its showing Page 0 of 0 even if there are records in the table.
This is the code which runs:
if( isset($this->params['named']['ajax']) && $this->params['named']['ajax'] == '1' )
{
$this->autoRender = false;
// get how many rows we want to have into the grid - rowNum parameter in the grid
$limit = $this->params['url']['rows'];
// get index row - i.e. user click to sort. At first time sortname parameter -
// after that the index from colModel
$sidx = $this->params['url']['sidx'];
// sorting order - at first time sortorder
$sord = $this->params['url']['sord'];
$page = $this->params['url']['page'];
// if we not pass at first time index use the first column for the index or what you want
if( !$sidx ) $sidx = 1;
// calculate the number of rows for the query. We need this for paging the result
$findconditions = array();
if(!empty($this->params['named']['batch']))
array_push(&$findconditions, array('Batch.id' => $this->params['named']['batch'] ));
$row = $this->Placement->find('count',array(
'link' => array(
'Student' => array(
'Batch'
)
),
'conditions'=> $findconditions
));
$count = $row;
// calculate the total pages for the query
if( $count > 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
$limit_range = $start . "," . $limit;
$sort_range = $this->modelClass . '.' . $sidx . " " . $sord;
$this->Placement->recursive = -1;
$where='';
if( $this->params['url']['_search'] == 'true' )
{
//pr($this->params);
$searchconditions = array();
if( isset($this->params['named']['batch']) && !empty($this->params['named']['batch']) )
{
$where.= " Batch.id =".$this->params['named']['batch'];
}
if( isset($this->params['url']['isstillworking']) && !empty($this->params['url']['isstillworking']) )
{
$where.= " AND Placement.isstillworking ='".$this->params['url']['isstillworking']."'";
}
if( isset($this->params['url']['studentname']) && !empty($this->params['url']['studentname']) )
{
$where.=" AND Student.fullname LIKE '" .$this->params['url']['studentname'] . "%'";
}
if( isset($this->params['url']['companyname']) && !empty($this->params['url']['companyname']) )
{
$where.=" AND Company.name LIKE '" .$this->params['url']['companyname'] . "%'";
}
if( isset($this->params['url']['salary']) && !empty($this->params['url']['salary']) )
{
$where.= " AND Placement.salary =".$this->params['url']['salary'];
}
if( isset($this->params['url']['contactnumber1']) && !empty($this->params['url']['contactnumber1']) )
{
$where.= " AND Student.contactnumber1 =".$this->params['url']['contactnumber1'];
}
if( isset($this->params['url']['batchname']) && !empty($this->params['url']['batchname']) )
{
$where.=" AND Batch.name LIKE '" .$this->params['url']['batchname'] . "%'";
}

$contactnumber1 =$result['Student']['contactnumber1'];
$response->rows[$i]['cell'] = array($student, $result['Placement']['isstillworking'], $result['Company']['name'], $result['Placement']['salary'], $contactnumber1, $batch);
$i++;
}
echo json_encode($response);
}
I am also attaching the screen shot for reference.
Please help me on this.

Why on earth would you not use Cake's ORM layer and Pagination class? If you use Model->query() you have to escape input yourself!
