我正在构建一个测试Lithium应用程序以了解它是如何工作的,我发现表单助手似乎无法识别我的数据被传回或任何验证错误。
目前我不得不手动传回我的错误,然后在视图中处理它们。
QuestionsController ::问
public function ask() {
if (!empty($this->request->data)) {
$question = Questions::create($this->request->data);
if ($question->save()) {
return $this->redirect(array('Questions::view', 'args'=>$question->id));
} else {
$errors = $question->errors();
}
if (empty($question)) {
$question = Questions::create();
}
return compact('question', 'errors');
}
}
视图/问题/ ask.html.php
<?php
// Assign the protected object to a variable so we can get at it
if(isset($question)){
$data = $question->data();
}else{
$data['title'] = '';
$data['text'] = '';
}
?>
<?=$this->form->create();?>
<?=$this->form->field('title', array('placeholder'=>'Title your question', 'value'=>$data['title']));?>
<?php if(isset($errors['title'])){
echo "<div class='alert alert-error'><a class='close' data-dismiss='alert' href='#'>×</a>";
foreach($errors['title'] as $e){
echo $e."<br/>";
}
echo "</div>";
}?>
<?=$this->form->field('text', array('placeholder'=>'Enter your question (supports Markdown)', 'type'=>'textarea', 'value'=>$data['text']));?>
<?php if(isset($errors['text'])){
echo "<div class='alert alert-error'><a class='close' data-dismiss='alert' href='#'>×</a>";
foreach($errors['text'] as $e){
echo $e."<br/>";
}
echo "</div>";
}?>
<p>Text input supports <?php echo $this->html->link('markdown', 'http://en.wikipedia.org/wiki/Markdown');?></p>
<?=$this->form->submit('Ask', array('class'=>'btn'));?>
<?=$this->form->end();?>
我可以从lithium\template\helper\Form
看到field()
方法可以采用template
参数,在示例中为<li{:wrap}>{:label}{:input}{:error}</li>
,因此帮助程序中有足够的容量用于显示验证信息。
那么如何在我的控制器中组织我的数据,以便将其传递回视图,以便帮助者填充我的字段并显示错误?
修改
我应该补充一点,示例'Sphere'应用程序,也使用此方法,它是标准的吗? (ref)

简短的回答是,您可以将表单绑定到Entity的子类,即Record或Document,如Form::create()
所示(链接缩写为{ {1}}打破了链接解析器。)
您的代码如下:
::
<?= $this->form->create($question); ?>
<?= $this->form->field('title'); ?>
<?= $this->form->field('text'); ?>
:
QuestionsController::ask()
public function ask() {
$question = Questions::create();
if (!empty($this->request->data)) {
if ($question->save($this->request->data)) {
return $this->redirect(array('Questions::view', 'args'=>$question->id));
}
}
return compact('question');
}
:
views/questions/ask.html.php
请注意,如果有以下情况,表单助手将自动显示错误:)
