我目前有以下型号:
class Category extends AppModel {
var $name = 'Category';
/*var $validate = array(
'name' => 'multiple'
);
no idea how to use this
*/
var $hasAndBelongsToMany = array(
'Post' => array(
'className' => 'Post'
)
);
class Post extends AppModel {
var $name = 'Post';
var $hasAndBelongsToMany = array(
'Category' => array(
'className' => 'Category'
)
);
var $belongsTo = array(
'Page' => array(
'className' => 'Page'
)
);
class Page extends AppModel {
var $name = 'Page';
var $order = array('Page.modified' => 'desc');
var $hasOne = array(
'Post' => array(
'className' => 'Post'
));
我在视图中也有这个表格:
<div id="content-wrap">
<div id="main">
<h2>Add Post</h2>
<?php echo $this->Session->flash();?>
<div>
<?php
echo $this->Form->create('Post');
echo $this->Form->input('Post.title');
echo $this->Form->input('Category.Category', array('multiple' => 'checkbox'));
echo $this->Form->input('Post.body', array('rows' => '3'));
echo $this->Form->input('Page.meta_keywords');
echo $this->Form->input('Page.meta_description');
echo $this->Form->end('Save Post');
?>
</div>
<!-- main ends -->
</div>
我的控制器:
function admin_add() {
// pr(Debugger::trace());
$this->set('categories', $this->Post->Category->find('list'));
if ( ! empty($this->data)) {
$this->data['Page']['title'] = $this->data['Post']['title'];
$this->data['Page']['layout'] = 'index';
if ($this->Post->saveAll($this->data)) {
$this->Session->setFlash('Your post has been saved', 'flash_good');
$this->redirect($this->here);
}
}
}
我遇到的问题是我可以在不为其选择类别的情况下保存帖子。
我尝试将以下内容添加到类别模型中:
var $validate = array(
'rule' => array('multiple', array('in' => array(1, 2, 3, 4))),
'required' => TRUE,
'message' => 'Please select one, two or three options'
);
帖子和页面模型验证。 如何激活类别的验证?
答案 0 :(得分:1)
首先,您尚未正确设置$validate
变量。 $validate
数组中的键必须为字段名称。其次,multiple
规则用于检查字段的值是否位于一组值中。
var $validate = array(
'color' => array(
'multiple' => array(
'rule' => array('multiple', array('in' => array('Red', 'Blue', 'Green'))),
'required' => false,
'message' => 'Please select one, two or three options'
),
),
);
我查看了书中multiple
的例子,这是一个错字。上面的代码是正确的。
接下来,如果您想验证相关模型,我建议您在beforeSave()
函数中执行此操作:
function beforeSave(){
if (isset($this->data['Category']['Category']) && empty($this->data['Category']['Category'])) {
return false;
}
return true;
}
这里,从beforeSave()返回false将阻止保存通过。因此,您将成功验证您的要求。
