我有一个SQL查询返回的这个对象数组,其中top_id是我的父ID字段:
Array (
[0] => stdClass Object ( [id] => 1 [top_id] => 0 [name] => Cat 1 )
[1] => stdClass Object ( [id] => 2 [top_id] => 0 [name] => Cat 2 )
[2] => stdClass Object ( [id] => 3 [top_id] => 0 [name] => Cat 3 )
[3] => stdClass Object ( [id] => 4 [top_id] => 2 [name] => Subcat 1 )
[4] => stdClass Object ( [id] => 5 [top_id] => 2 [name] => …我需要在自定义Laravel Validator类中的一些验证方法中访问Db存储库,该类扩展了LaravelValidator.怎么弄？
我的类构造函数:
<?php namespace Pongo\Cms\Support\Validators;
use Illuminate\Validation\Validator as LaravelValidator;
use Pongo\Cms\Support\Repositories\PageRepositoryInterface as Page;
use Pongo\Cms\Support\Repositories\ElementRepositoryInterface as Element;
class PongoValidator extends LaravelValidator {
/**
* Class constructor
* @param Page $page
* @param Element $element
*/
public function __construct($translator, $data, $rules, $messages, Page $page, Element $element)
{
$this->page = $page;
$this->element = $element;
}
[...]
和我的Validator解析器(如Laravel文档):
<?php
/**
* Instantiate CustomValidator class
*/
Validator::resolver(function($translator, $data, $rules, $messages)
{
return new Pongo\Cms\Support\Validators\PongoValidator($translator, $data, $rules, $messages);
});
如何使它工作？谢谢
是否可以使用常规MongoDB的本地实例代替默认的minimongo来启动一个新的Meteor项目？
如果是这样,怎么样？
我有这种情况:
一个db表'pageitems'用
zone | text
------------
ZONE1 text1
ZONE2 text2
ZONE3 text3
ZONE3 text4
在这样的foreach循环中
foreach($pageitems as $items) {
...
}
我想获得这样的数组
Array
(
[ZONE1] => Array(
[0] => text1
)
[ZONE2] => Array
(
[0] => text2
)
[ZONE3] => Array
(
[0] => text3,
[1] => text4
)
)
怎么获得这个？谢谢
