在上一章节中，我们使用对话框（dialog）组件创建了 CRUD 应用来创建和编辑用户信息。本教程我们将告诉您如何创建一个 CRUD 数据网格（DataGrid）。 我们将使用 可编辑的数据网格（DataGrid）插件 来完成这些 CRUD 操作动作。
<table id="dg" title="My Users" style="width:550px;height:250px" toolbar="#toolbar" idField="id" rownumbers="true" fitColumns="true" singleSelect="true"> <thead> <tr> <th field="firstname" width="50" editor="{type:‘validatebox‘,options:{required:true}}">First Name</th> <th field="lastname" width="50" editor="{type:‘validatebox‘,options:{required:true}}">Last Name</th> <th field="phone" width="50" editor="text">Phone</th> <th field="email" width="50" editor="{type:‘validatebox‘,options:{validType:‘email‘}}">Email</th> </tr> </thead> </table> <div id="toolbar"> <a href="#" class="easyui-linkbutton" iconCls="icon-add" plain="true" onclick="javascript:$(‘#dg‘).edatagrid(‘addRow‘)">New</a> <a href="#" class="easyui-linkbutton" iconCls="icon-remove" plain="true" onclick="javascript:$(‘#dg‘).edatagrid(‘destroyRow‘)">Destroy</a> <a href="#" class="easyui-linkbutton" iconCls="icon-save" plain="true" onclick="javascript:$(‘#dg‘).edatagrid(‘saveRow‘)">Save</a> <a href="#" class="easyui-linkbutton" iconCls="icon-undo" plain="true" onclick="javascript:$(‘#dg‘).edatagrid(‘cancelRow‘)">Cancel</a> </div>
$(‘#dg‘).edatagrid({ url: ‘get_users.php‘, saveUrl: ‘save_user.php‘, updateUrl: ‘update_user.php‘, destroyUrl: ‘destroy_user.php‘ });
我们应该提供 ‘url‘、‘saveUrl‘、‘updateUrl‘ 和 ‘destroyUrl‘ 属性来编辑数据网格（DataGrid）：
保存一个新的用户（save_user.php）：
$firstname = $_REQUEST[‘firstname‘]; $lastname = $_REQUEST[‘lastname‘]; $phone = $_REQUEST[‘phone‘]; $email = $_REQUEST[‘email‘]; include ‘conn.php‘; $sql = "insert into users(firstname,lastname,phone,email) values(‘$firstname‘,‘$lastname‘,‘$phone‘,‘$email‘)"; @mysql_query($sql); echo json_encode(array( ‘id‘ => mysql_insert_id(), ‘firstname‘ => $firstname, ‘lastname‘ => $lastname, ‘phone‘ => $phone, ‘email‘ => $email ));
更新一个已存在用户（update_user.php）：
$id = intval($_REQUEST[‘id‘]); $firstname = $_REQUEST[‘firstname‘]; $lastname = $_REQUEST[‘lastname‘]; $phone = $_REQUEST[‘phone‘]; $email = $_REQUEST[‘email‘]; include ‘conn.php‘; $sql="update users set firstname=‘$firstname‘,lastname=‘$lastname‘,phone=‘$phone‘,email=‘$email‘ where id=$id"; @mysql_query($sql); echo json_encode(array( ‘id‘ => $id, ‘firstname‘ => $firstname, ‘lastname‘ => $lastname, ‘phone‘ => $phone, ‘email‘ => $email ));
删除一个已存在用户（destroy_user.php）：
$id = intval($_REQUEST[‘id‘]); include ‘conn.php‘; $sql = "delete from users where id=$id"; @mysql_query($sql); echo json_encode(array(‘success‘=>true));
