我正在使用Laravel表格。
到目前为止，我已经成功为项目中的商品创建了CRUD，但有一件事情困扰我：
如何在图像列表中而不是特定的编辑页面上设置“删除”按钮？
所以，这是我的代码：
包含：
use App\ImageTracking;
use App\Image;
use DB;
餐桌优惠：
public function up()
{
Schema::create('offers', function (Blueprint $table) {
$table->increments('idOffers')->unsigned();
$table->integer('id_spons')->unsigned();
$table->foreign('id_spons')->references('id_sponsors')->on('sponsors')->onDelete('cascade')->onUpdate('cascade');
$table->string('Name_offre');
$table->string('title');
$table->string('subject');
$table->string('froms');
$table->string('TrackingURL');
$table->string('subId');
$table->string('unSub');
//->onDelete('cascade')->onUpdate('cascade');
$table->timestamps();
});
}
表格图片：
public function up()
{
Schema::create('image', function (Blueprint $table) {
$table->increments('id_imageUnsb');
$table->integer('offers_id')->unsigned();
$table->foreign('offers_id')->references('idOffers')->on('offers')->onDelete('cascade')->onUpdate('cascade');
$table->string('imageUnsb');
$table->timestamps();
});
}
<tbody>
@foreach($offers->Images as $image)
<tr>
<td><img src="{{ url('storage/photo/'.$image->imageUnsb) }}" width="100px" height="100px"></td>
<td>
<form action=" {{ url('/offers/'.$image->idOffers) }}" method="post">
{{ csrf_field() }}
{{ method_field('DELETE') }}
<button type="submit" class="deleteConfirmation btn btn-danger">Delete</button>
</form>
</td>
</tr>
@endforeach
</tbody>
和我的控制器：
public function destroyImageUnsb(Request $request, $id)
{
$image = Image::where('offers_id', $id)->first()->delete();
return redirect('editOffers');
}
路线：
Route::delete('/offers/{idOffers}','OffersController@destroyImageUnsb');
答案 0 :(得分：3)
您应该尝试以下操作：
路线
Route::get('/offers/{idOffers}','OffersController@destroyImageUnsb')->name('offers');
您的视图
@foreach($offers->Images as $image)
<tr>
<td><img src="{{ url('storage/photo/'.$image->imageUnsb) }}" width="100px" height="100px"></td>
<td>
<a href="{{ route('offers', [$image->offers_id]) }}" class="btn btn-xs btn-primary">Delete</a>
</td>
</tr>
@endforeach
您的控制器功能
use Redirect;
public function destroyImageUnsb($id)
{
$image = Image::where('offers_id', $id)->delete();
return Redirect::to('editOffers/'.$id);
}
请按照以下方式更新您的editoffers路线：
Route::get('/editOffers/{id}','OffersController@edit');
更新后的答案
您的视图
@foreach($offers->Images as $image)

<td>
<a href="{{ route('offers', [$image->id_imageUnsb]) }}" class="btn btn-xs btn-primary">Delete</a>
</td>

use Redirect;

$image = Image::where('id_imageUnsb', $id)->delete();
return Redirect::to('editOffers/'.$offerId);
}

如果您是 laravel 的新手，或者您的 project is small 跳过此答案
打开可能是Offer的模型并将以下代码粘贴到其中

if you are not well in JavaScript Just Use My Function toolTipScript()
|--------------------------------------------------------------------------

|Generates the buttons while displaying the table data in laravel
|when the project is bigger and if you are laravel expert you this.
|But if you are the learner just go with basic

好，现在打开您的列表文件，可能是index.blade.php
@foreach($offers->Images as $image)
<tr>
<td><img src="{{ url('storage/photo/'.$image->imageUnsb) }}" width="100px" height="100px"></td>
<td>{!!App\Offer::tableActionButtons(url()->full(),$image->id,$image->id,['show','edit','delete'])!!}</td>
@endforeach
如果需要图标
dont forgot to add fontawesome css
答案 2 :(得分：0)
尝试这个：
@foreach($users as $key => $user)
{!! Form::open(['route' => ['offers', $user->id],'method' => 'POST','style' => 'display:inline-block'])!!}
{{ Form::submit(($user->status == 1) ? 'Ban User' : 'Activate User', ["class"=> "btn btn-red confirm-action"]) }}
{!! Form::close() !!}
@endforeach
