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

	}
	
	//buat ambil data dari db menggunakan jquery n json
	function getOrder()
	{
	$no=trim($this->input->post('id'));
	$hasil=$this->MOrder->getOrder($no);
	$datetime = strtotime($hasil['modified']);
	$orderdate = date("d-m-y H:i ", $datetime);
	$array=array('modified'=>$orderdate);
	echo json_encode($array);			
	}

Are there anything wrong with my codes?What should i do?Thanks a lot...

Yonghan,

In these lines (and maybe others), checkboxes, Update buttons and hidden input fields all get the same id and name on each pass through the foreach loop. It therefore appears that the javascript/jquery code has no way to distinguish one row from another.

$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'].'" />';
