Php laravel刀片:测试数组是否包含值
我想测试数组是否包含值 我有两个数组:Php laravel刀片:测试数组是否包含值,php,laravel,blade,Php,Laravel,Blade,我想测试数组是否包含值 我有两个数组: var_dump($ingredients) array (size=12) 0 => object(stdClass)[303] public 'id' => int 21 public 'nom' => string 'Tomate' (length=6) public 'created_at' => null public 'updated_at' => nu
var_dump($ingredients)
array (size=12)
0 =>
object(stdClass)[303]
public 'id' => int 21
public 'nom' => string 'Tomate' (length=6)
public 'created_at' => null
public 'updated_at' => null
1 =>
object(stdClass)[111]
public 'id' => int 22
public 'nom' => string 'Carotte' (length=7)
public 'created_at' => null
public 'updated_at' => null
2 =>
object(stdClass)[302]
public 'id' => int 23
public 'nom' => string 'Pommes' (length=6)
public 'created_at' => null
public 'updated_at' => null

public 'updated_at' => string '2017-07-23 07:06:31' (length=19)
var_dump($composant)
array (size=3)
0 => object(stdClass)[321]
public 'nom' => string 'Anchoix' (length=7)
1 =>
object(stdClass)[322]
public 'nom' => string 'Roquette' (length=8)
2 =>
object(stdClass)[323]
public 'nom' => string 'Thon' (length=4)
我想检查$composant中包含哪些成分,以便我可以指定是否必须选中该复选框
@foreach($ingredients as $item)
@if(in_array($item->nom,$composants,true))
{!! Form::checkbox($item->nom,$item->nom, true) !!} {!! $item->nom !!}
@else
{!! Form::checkbox((string)$item->nom,$item->nom, false) !!} {!! $item->nom !!}
@endif
@endforeach
但是我的if语句返回的总是错误的。
为什么 如果您的
$composants
不是来自集合对象,请尝试创建一个集合对象,然后将其删除
// will only select the 'nom' values
$composants = collect($composants)->pluck('nom');
否则,您可以简单地执行以下操作:
$composants = $composants->pluck('nom');
因为
in_array
不知道组件的内部结构以及我该做什么??@u_mulder你帮了我很多…当然,现在你知道in_array
对你没有帮助了)组件的值是多少?
