如何在 Livewire 中使用嵌套表单字段?
How to use Nested Form Fields in Livewire?
我有一个名为 project-form
的组件,我又在其中调用了另一个名为 search-users
的组件。问题是我无法从嵌套组件即 search-users
.
中设置 ProjectForm
中的 $members
属性
据我所知,$members
必须在 SearchUsers.php
中进行设置,但我希望必须在 ProjectForm.php
中进行设置,以便我可以保存在数据库中。
项目-form.blade.php
<form wire:submit.prevent="submit">
<input wire:model="name"/>
<input wire:model="category"/>
<input wire:model="target_date"/>
@livewire('search-users')
</form>
ProjectForm.php
<?php
namespace App\Http\Livewire;
use App\Models\Project;
use Livewire\Component;
class ProjectForm extends Component
{
public string $name = '';
public string $category = '';
public string $target_date = '';
public array $members = [];
protected $rules = [
'name' => 'required',
'category' => 'required',
'target_date' => 'required',
];
public function submit(){
$validated = $this->validate();
Project::create($validated);
toastr()->success('Project Created Successfully');
}
public function render()
{
return view('livewire.project-form');
}
}
搜索-users.blade.php
@foreach($users as $user)
<label class="list-group-item ps-0 border-0 d-flex justify-content-between align-items-center">
<div class="d-flex align-items-center">
<img alt="{{ $user->name }}" src="{{ url('storage/'.$user->avatar) }}" width="35" class="me-3 rounded-circle mx-auto d-block">
{{ $user->name }}
</div>
<input class="form-check-input me-1" wire:model.defer="members" type="checkbox" value="{{ $user->id }}">
</label>
@endforeach
正如@Qirel 已经建议的那样,您应该使用 Livewire events。
在您的搜索组件中,您可以发出事件 memebersFound
并将搜索中的成员作为参数传递(请参阅 Livewire Passing parameters in events),如下所示
$this->emit('membersFound', $membersFound);
然后,在您的 ProjectForm 组件中您应该监听这个事件
protected $listeners = [
'membersFound' => 'addMembers'
];
public function addMembers(array $members)
{
$this->members = $members;
}
