/**
*第一步：加載helper
*/
$this->load->helper('grid_helper');
$this->load->helper('url_helper');

//第二步：初始化表格參數
$aData = array(
'set_columns' => array(
array(
'label' => 'Customer ID',
'name' => 'custid',
'width' => 100,
'size' => 10
),
array(
'label' => 'Customer Name',
'name' => 'custname',
'width' => 220,
'size' => 10
),
array(
'label' => 'Status',
'name' => 'custstatus',
'width' => 100,
'size' => 10
)
),
'div_name' => 'grid',
'source' => 'customer/customerList/',
'sort_name' => 'custname',
'add_url' => 'customer/exec/add',
'edit_url' => 'customer/exec/edit',
'delete_url' => 'customer/exec/del',
'caption' => 'Customer Maintenance',
'primary_key' => 'custid',
'grid_height' => 230
);

其中各參數的含義為：
set_columns:

表格中的列 (可以通過修改 grid_helper.php增加更多的列選項).

div_name:

source: The url parameter where the data would be fetched (I will tell you the contents of /customer/customerlist/ later).
sort_name: The column name that is sorted by default.
delete_url, add_url, edit_url: is the the jquery would redirect when editing,adding or deleting a record.
caption: Caption in the grid’s title bar.
primary_key: The primary key in your grid, this key would be passed when you are editing or deleting a record when the appropriate action button is pressed.
grid_height: set the height of the grid.

我們需要在控制器中構造一個函數用于取回數據.例如： /customer/customerlist/. 獲取客戶列表的代碼如下：

buildGridData(
array(
'model' => 'customer_model',
'method' => 'getAllCustomers',
'pkid' => 'custid',
'columns' => array( 'custid','custname','custstatus' )
)
);

我使用在grid_helper.php中定義的buildGridData函數,你只需要指定model名字,model的方法，如：

function getAllCustomers($paramArr) {
$start = isset($paramArr['start'])?$paramArr['start']:NULL;
$limit = isset($paramArr['limit'])?$paramArr['start']:NULL;
$sortField = isset($paramArr['sortField'])?$paramArr['sortField']:'custname';
$sortOrder = isset($paramArr['sortOrder'])?$paramArr['sortOrder']:'asc';
$whereParam = isset($paramArr['whereParam'])?$paramArr['whereParam']:NULL;
if(!empty($start) && !empty($limit)) $optLimit = "limit $start,$limit";
else $optLimit = NULL;

if(!empty($whereParam)) $whereParam = "and (".$whereParam.")";
$whereClause = "where true ".$whereParam;

$SQL = "SELECT * FROM tblcustomer $whereClause order by $sortField $sortOrder $optLimit ";
$result = $this->db->query($SQL);

if($result->num_rows() > 0) {
$custlist = $result->result();
return $custlist;
} else {
return null;
}
}

現在可以構造表格并在視圖中加載它:

$data['customerGrid'] = buildGrid($aData);
$this->load->view( 'customer/customerlist',$data );

現在你只需要在視圖中打印customerGrid.不要忘記增加一個表格其 id=”grid” ，增加一個 div，其id=”pager”。

<?php echo $customerGrid; ?>

至此，所有工作已經完畢！

附： library 和 helper代碼
