Upload image in update Laravel
提问by Pierangelo Orizio
in Laravel5 I can't update image in Edit, when I upload new file, this result null... Below my code in controller, routes and edit view.
在 Laravel5 中，我无法在编辑中更新图像，当我上传新文件时，此结果为空...在控制器、路由和编辑视图中的代码下方。
here my controller:
这是我的控制器：
public function update(Request $request, $id)
{
$slider = Slider::findOrFail($id);
//$input = $request->all();
// uploads image
if ($request->hasFile('image'))
{
$file = $request->file('image');
$imagename = 'dpgomma_' . time() . '-' . $file->getClientOriginalName();
$file->move(public_path().'/uploads/', $imagename);
$input['image'] = $imagename;
}
$slider->save($request->all());
return redirect('/admin/sliders')->with('message', 'Slider Modificata');
}
my routes:
我的路线：
Route::get('/admin/sliders/edit/{id}', 'SliderController@edit');
Route::put('/admin/sliders/update/{id}',['as' => 'sliders.update', 'uses' => 'SliderController@update']);
My view form:
我的视图形式：
{!! Form::model($slider, [
'method' => 'put',
'route' => ['sliders.update', $slider->id],
'files' => true
]) !!}
{!! Form::token() !!}
<div class="form-group">
{!! Form::label('title', 'Title:', ['class' => 'control-label']) !!}
{!! Form::text('title', null, ['class' => 'form-control']) !!}
</div>
<div class="form-group">
{!! Form::label('image', 'image:', ['class' => 'control-label']) !!}
{!! Form::file('image', null, ['class' => 'form-control']) !!}
</div>
{!! Form::submit('Update Task', ['class' => 'btn btn-primary']) !!}
{!! Form::close() !!}

You have to add the 'files' => trueoption in your Form opening.
您必须'files' => true在表单打开中添加该选项。
Also, you can use $request->hasFile('image')and $request->file('image')instead of the Inputfacade.
此外，您可以使用$request->hasFile('image')and$request->file('image')代替Input外观。
I suggest you to take a look at this, there's no more reason not to work.
我建议你看看这个，没有理由不工作了。

Your database is not updating image name because the image name contains in input['image']and you updating your database with $requestservice container. So, the original name of your image going through $request service container like
您的数据库没有更新图像名称，因为图像名称包含在input['image']并且您使用$request服务容器更新数据库。因此，您的图像的原始名称通过 $request 服务容器，例如
$request = [
'other' => 'other',
'image' => 'you_original_image_name',
'more_other' => 'more_other'
]
To update the database with desire file name change this line
要使用所需的文件名更新数据库，请更改此行
$input['image'] = $imagename;
To
到
$request['image'] = $imagename;
