在创建或编辑对象时，我有一个jquery对话框，可以打开View以进行编辑或在其中添加对象。当他们提交时，一切正常。我还添加了验证检查，但是如果有任何验证错误，会发生什么，对话框关闭，用户被重定向到带有验证错误消息的实际页面。
我想要做的是在对话框中显示验证错误，而不是转到页面。我环顾四周，看到我可能不得不使用ajax，但我不知道如何开始。
这是我的模型的代码。我删除了一些额外的东西以保持简短。
class LocalClock extends AppModel
{
public $useDbConfig = 'default';
public $useTable = 'local_clocks';
public $validate = array(
'utc_offset_sec' => array(
'rule' => 'notEmpty',
'rule' => 'numeric',
'message' => 'Please Enter a Valid Number'
),
'in_month' => array(
'rule' => 'notEmpty',
'rule' => 'numeric',
'message' => 'Please Enter a Valid Number'
),
'in_week' => array(
'rule' => 'notEmpty',
'rule' => 'numeric',
'message' => 'Please Enter a Valid Number'
),
'in_day' => array(
'rule' => 'notEmpty',
'rule' => 'numeric',
'message' => 'Please Enter a Valid Number'
),
'in_hour' => array(
'rule' => 'notEmpty',
'rule' => 'numeric',
'message' => 'Please Enter a Valid Number'
)
);
public function setStatType( $type )
{
$this->table = 'local_clocks';
$this->_schema = array(
'col1' => array('type' => 'int'),
'col2' => array('type' => 'string'),
'col3' => array('type' => 'string'),
'col4' => array('type' => 'string'),
'col5' => array('type' => 'string'),
}
}
?>
以下是我的控制器的代码：
class LocalClocksController extends AppController
{
public $components = array('RequestHandler', 'Session'); // enable checking for incoming request attributes
public $helpers = array('Html', 'Form', 'Session', 'Javascript', 'Paginator');
public $paginate = array(
'limit' => 10,
'order' => array(
'LocalClock.id' => 'asc'
)
);
public function index()
{
$this->LocalClock->table = 'local_clocks';
$this->LocalClock->getDataSource()->tableFields['local_clocks'] = array( "id", "name", "auto_offset", "utc_offset_sec", "in_month", "in_week", "in_day", "in_hour", "out_month", "out_week", "out_day", "out_hour", "offset_sec");
if ($this->RequestHandler->accepts('xml'))
{
// xml handler
$this->set('localClocks', $this->LocalClock->find('all'));
$this->set('_serialize', array('local_clocks'));
$data = $this->paginate('LocalClock');
$this->set('localClocks', $data);
}
elseif ($this->RequestHandler->accepts('json'))
{
//json handler
$this->set('localClocks', $this->LocalClock->find('all'));
$this->set('_serialize', array('local_clocks'));
$data = $this->paginate('LocalClock');
$this->set('localClocks', $data);
}
elseif( $this->RequestHandler->accepts('html'))
{
//html handler
//$this->LocalClock->getDataSource()->tableFields['local_clocks'] = array( "id", "name", "auto_offset", "utc_offset_sec", "in_month", "in_week", "in_day", "in_hour", "out_month", "out_week", "out_day", "out_hour", "offset_sec");
$this->set('localClocks', $this->LocalClock->find('all'));
$data = $this->paginate('LocalClock');
$this->set('localClocks', $data);
}
}
public function add()
{
if ($this->request->is('post'))
{
if ($this->LocalClock->save($this->request->data))
{
$this->set('localClocks', $this->request->data);
$this->LocalClock->save($localClocks);
$this->Session->setFlash('Local Clock: '. $this->request->data['LocalClock']['name'] . ' has been created.');
$this->redirect(array('action' => 'index'));
}
else
{
$this->Session->setFlash('Unable to add new Local Clock.');
}
}
}
public function edit($id = null)
{
$this->LocalClock->id = $id;
if ($this->request->is('get'))
{
$this->request->data = $this->LocalClock->read();
$this->set('localClocks', $this->LocalClock->read());
}
else
{
if ($this->LocalClock->save($this->request->data))
{
$this->Session->setFlash('Local Clock: '. $this->request->data['LocalClock']['name'] . ' has been updated.');
$this->redirect(array('action' => 'index'));
}
else
{
$this->Session->setFlash('Unable to update Local Clock: '. $this->request->data['LocalClock']['name']);
$this->set('localClocks', $this->request->data);
}
}
}
?>
这是我的index.ctp的代码：
<link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.9/themes/start/jquery-ui.css" type="text/css" media="all" />
<p> <?php echo $this->Paginator->prev('« Previous', null, null, array('class' => 'disabled')); ?>;

$(function()
{
var $dialog = $("#edit_dialog").dialog(

autoOpen: false,

$(".edit_dialog").click(function()

最后这是我的edit.ctp：

<div>
<?php echo $this->Form->create('LocalClock', array('action' => 'edit', 'inputDefaults' => array('label' => false))); ?>

<?php echo $this->Form->end('Save Changes'); ?>
</div>
如果我可以获得编辑对话框的帮助并在不关闭和重定向到页面的情况下进行验证，那么我应该能够对添加功能执行相同的操作。
感谢您的帮助， 如果有什么不清楚或者是否有人需要更多信息，请告诉我。
答案 0 :(得分：1)
要解决这个问题，首先在编辑文件的末尾添加一个ajax提交按钮，就在$ this-＆gt; Form-＆gt; end（）之前。 （删除括号中的“保存更改”，因为可以更改ajax提交说明。）
<?php
// The Ajax Helper submit is used to submit the changes made to the edit form
// because it allows the modal window to be loaded with the updated edit view
// without leaving the modal window.
echo $this->Ajax->submit('Save Changes', array(
'url' => array('controller' => 'localClocks', 'action' => 'edit'),
'update' => 'editTable'));
// Call the close Dialog() function if data was validated sucessfully; valid == true.
// Else it stays open displaying validation error message.
if (false != $valid)
{
echo "<script>closeDialog()</script>";
}
echo $this->Form->end(); ?>
接下来在控制器文件中，将编辑功能更改为：
public function edit($id = null)
{
$this->LocalClock->id = $id;
$this->set('valid', false);
if ($this->request->is('get'))
{
$this->request->data = $this->LocalClock->read();
$this->set('localClocks', $this->LocalClock->read());
}
else
{
if ($this->LocalClock->save($this->request->data))
{
$this->Session->setFlash('Local Clock: '. $this->request->data['LocalClock']['name'] . ' has been updated.');
$this->set('valid', true);
//$this->redirect(array('action' => 'index'));
}
else
{
$this->Session->setFlash('Unable to update Local Clock: '. $this->request->data['LocalClock']['name']);
$this->set('localClocks', $this->request->data);
$this->set('valid', false);
}
}
}
这里唯一的新功能是代码为变量分配一个布尔值，以确定是否关闭对话框，具体取决于是否存在验证错误。
就是这样。它插入其他所有东西。 我希望这能帮助别人。
