CRUD application delete not working [resolved]

[andyj]

I have built a datagrid with pop up form editing based on the CRUD application demo
http://www.jeasyui.com/tutorial/app/crud.php

Everything works fine, except the delete record function.
It fires, the prompt comes up, no error message but I don't think it's getting the record ID for some reason.
Can anyone see anything incorrect in my code? Thanks

Javascript delete function:

Code:

		function deleteRecord(){
			var row = $('#dg').datagrid('getSelected');
			if (row){
				$.messager.confirm('Confirm','Are you sure you want to delete this record?',function(r){
					if (r){
						$.post('data_delete.php',{id:row.id},function(result){
							if (result.success){
								$('#dg').datagrid('reload');	// reload the user data
							} else {
								$.messager.show({	// show error message
									title: 'Error',
									msg: result.msg
								});
							}
						},'json');
					}
				});
			}
		}

Datagrid html:

Code:

				<table id="dg" title="Classes" class="easyui-datagrid" 
							url="data_select.php" idField="class_id" striped="true" loadMsg="Hey patience is a virtue"
							toolbar="#toolbar" pagination="true" pageSize="30"
							rownumbers="true" fitColumns="true" showFooter="true" singleSelect="true"
							data-options="onDblClickRow:function(rowIndex, rowData){
							editRecord();}">
						<thead>
							<tr>
								<th id="idclass_id" field="class_id" width="35" align="right">ID</th>
								<th id="idTimeCreated" field="TimeCreated" width="80">Created</th>
								<th id="idTimeModified" field="TimeModified" width="80">Last Modified</th>
								<th id="idClass" field="Class" >Class</th>
								<th id="dgIsActive" field="IsActive" width="80">Active?</th>
								<th id="idsortorder" field="sortorder" width="80">Sort Order</th>
							</tr>
						</thead>
					</table>
	<div id="toolbar">
		<a href="#" class="easyui-linkbutton" iconCls="icon-add" plain="true" onclick="insertRecord()">New Line Item</a> | 
		<a href="#" class="easyui-linkbutton" iconCls="icon-edit" plain="true" onclick="editRecord()">Edit Line Item</a> | 
		<a href="#" class="easyui-linkbutton" iconCls="icon-remove" plain="true" onclick="deleteRecord()">Remove Line Item</a>
	</div>

data_delete.php file:

Code:

<?php
$id = intval($_REQUEST['class_id']);
include '../../common/conn.php';
$sql = "DELETE FROM class where class_id=$id";
$result = @mysql_query($sql);
if ($result){
	echo json_encode(array('success'=>true));
} else {
	echo json_encode(array('msg'=>'An error occurred while attempting to delete the record.'));
}
?>

Thanks for any insights...

Please replace your code

Code:

$.post('data_delete.php',{id:row.id},function(result){
//...
});

with

Code:

$.post('data_delete.php',{class_id:row.class_id},function(result){
//...
});
