我有一张桌子@Query("_class:your package name here.AnimalEntity")
public AnimalEntity findAllAnimals();
,在这里我要把父母的孩子放在同一张桌子上。到现在为止,一切都很好,但是当我以表格形式显示这些内容时遇到了问题。我在同一张桌子上有4个或5个级别的父母子女。
我的礼物account_heads
就像下面的东西
loop
我的帐户@foreach ($accountHeads as $accountHead)
@foreach ($accountHead->children as $children)
<option value="{{ $children->id }}">{{ $children->name }} @if($children->code) ({{ $children->code }})@endif</option>
@foreach($children->children as $c1)
<option value="{{ $c1->id }}"> -- {{ $c1->name }} @if($c1->code) ({{ $c1->code }})@endif</option>
@foreach($c1->children as $c2)
<option value="{{ $c2->id }}"> ---- {{ $c2->name }} @if($c2->code) ({{ $c2->code }})@endif</option>
@foreach($c2->children as $c3)
<option value="{{ $c3->id }}"> ------ {{ $c3->name }} @if($c3->code) ({{ $c3->code }})@endif</option>
@foreach($c3->children as $c4)
<option value="{{ $c4->id }}"> -------- {{ $c4->name }} @if($c4->code) ({{ $c4->code }})@endif</option>
@foreach($c4->children as $c5)
<option value="{{ $c5->id }}"> ---------- {{ $c5->name }} @if($c5->code) ({{ $c5->code }})@endif</option>
@foreach($c5->children as $c6)
<option value="{{ $c6->id }}"> ------------ {{ $c6->name }} @if($c6->code) ({{ $c6->code }})@endif</option>
@endforeach
@endforeach
@endforeach
@endforeach
@endforeach
@endforeach
@endforeach
@endforeach
的{{1}}方法如下-
AccountHeadsController
create
模型就像是波纹管
public function create()
{
$accountHeads = AccountHead::with('children')->where('parent_id', 0)->get();
return view('account.account-head.create', compact('accountHeads'));
}
答案 0 :(得分:1)
我自己是这样做的:
创建的帮助程序文件:App / Helpers / MyHelper.php
MyHelper.php文件:
<?php
namespace App\Helpers;
class MyHelper
{
public static function dd($array, $step = 0)
{
$output = '';
foreach($array as $arr)
{
$output .= '<option value="'.$arr->id.'">'.str_repeat(' ',$step). $arr->name.'</option>';
if($arr->children)
{
$output .= self::dd($arr->children, $step+1);
}
}
return $output;
}
}
并将其添加到别名下的/config/app.php中。
'MyHelper' => App\Helpers\MyHelper::class,
然后在您的视图中可以使用:
<select>
{!! MyHelper::dd($accountHeads) !!}
</select>
