<script type="text/javascript" src="<?php echo base_url(); ?>js/jquery.form.js"></script>

<script type="text/javascript"> 
// wait for the DOM to be loaded 
$(document).ready(function() 
{ 
$("#msg").hide();
$('#myform').ajaxForm(function()
{
	var no_id=$('#no_id').val();

	$.post("getOrder/", { 'id' : no_id },
	function(data){
$('#modif').html(data.modified);
}, "json");

	//nampilin di div message string yg ada di dalam html()
	$("#msg").html("Berhasil update order").fadeIn(1500);
	$("#msg").fadeOut(1500);
	});
}); 
</script> <h1><?php echo $title;?></h1>
<?php
if ($this->session->flashdata('message')){
echo "<div class='message' name='msg' id='msg'>".$this->session->flashdata('message')."</div>";
}
echo "<div name='msg' class ='msg' id='msg'></div>";

echo "<table border='1' cellspacing='0' cellpadding='3' width='100%' id='order_home' name='order_home'>\n";
echo "<tr valign='top'>\n";
echo "<th>No Order</th>\n<th>No Cust</th><th>Tgl Pesan</th><th>Modified</th><th>Status</th><th>Update</th><th>id</th><th>Actions</th>\n";
echo "</tr>\n";
if (count($order)){
foreach ($order as $key => $list){
	echo "<tr valign='top'>\n";
	echo "<td>".anchor("admin/order/detail/".$list['no_order'],$list['no_order'])."</td>\n";
	echo "<td>".$list['custid']."</td>\n";
	$datetime = strtotime($list['tgl_pesan']);
	$orderdate = date("d-m-y H:i ", $datetime);
	echo "<td>".$orderdate."</td>\n";
	$modifieddate = strtotime($list['modified']);
	$modified = date("d-m-y H:i ", $modifieddate);
	echo "<td id='modif' name='modif'>".$modified."</td>\n";
	$attributes = array('id' => 'myform');
	echo form_open('admin/order/edit',$attributes);
	echo "<td align='center'>".form_dropdown('status',$status,$list['status'])."</td>\n";
	$btn = array('id'=>'update','name'=>'update','value'=>'Update'); 
	$data = array('name'=>'notif','id'=>'notif');
	echo "<td align='center'>".form_checkbox($data)."<label for='update'>Notifikasi cust</label>".form_submit($btn)."</td>\n";
       	echo '<input type="hidden" id="no_id" name="no_id" value="'.$list['id'].'" />';
	echo form_close();
	echo "<td align='center'>";
	echo anchor("admin/order/edit/".$list['no_order'],img(base_url().'/images/edit.jpg'));
	echo " | ";
	echo anchor("admin/order/delete/".$list['no_order'],img(base_url().'/images/delete.jpg'));
	echo "</td>\n";
	echo "</tr>\n";
}
}
echo "</table>";
?>

 

controller/order

}

//buat ambil data dari db menggunakan jquery n json
function getOrder()

}
