Question

我制作了一份更新表格，可以在其中编辑和更新我的租赁商店项目中的当前上传内容。但是我一直遇到这个问题，其中页面和数据库中的图像都没有改变，但是当我检查存储/公共/图像时，只要我尝试再次尝试，它就会存储相同的当前图像。

但是我表单中的其余部分都可以正常工作，并且除了图像之外已经可以更改了。

这是在我的CarsController.php中

public function update(Request $request, $id)
{
    $car = Car::find($id);

    $car->car_brand = $request->car_brand;
    $car->car_name = $request->car_name;
    $car->description = $request->description;
    $car->car_type_id = $request->car_type_id;

    if ($request->hasFile('image_location')) {
        Storage::disk('public')->delete($car->image_location); // remove the old file.
        $path = $request->image_location->store('images', 'public'); // save the new image.
        $car->image_location = $path;
    }

    $car->save();
    $request->session()->flash('message', 'The item has been updated.');

    return redirect('/selections');

}

这是表格

<div class="form-group">
    <label>Image</label>
    <input type="file" class="form-control" name="image_location" required>
</div>

我不知道可能有什么问题。任何人请赐教。提前致谢。无论如何，迁移的列名称是image_location

这也是在我的store（）

public function store(Request $request)
{
    $car = new car;

    $car->car_brand = $request->car_brand;
    $car->car_name = $request->car_name;
    $car->description = $request->description;
    $car->car_type_id = $request->car_type_id;

    $path = $request->image_location->store('images', 'public');
    $car->image_location = $path;
    $car->availability = $request->availability;

    $car->save();
    $request->session()->flash('message', 'The item has been added.');

    return redirect('/selections');
}

恐怕您的代码对我来说是完美的。

您可以尝试添加一些日志行，看看问题出在哪里：

use Illuminate\Support\Facades\Log;

if ($request->hasFile('image_location')) {
    Log::debug('File has been found in request.');

    // Check if the old car image exists.
    Log::debug($car->image_location . (Storage::disk('public')
            ->exists($car->image_location)? ' exists': ' does not exist'));

    Storage::disk('public')->delete($car->image_location); // Remove the old file.

    // Check if the old car image (if it existed) has been deleted.
    Log::debug($car->image_location . (Storage::disk('public')
            ->exists($car->image_location)? ' exists': 'does not exist'));

    $path = $request->image_location->store('images', 'public'); // save the new image.

    // Check if the new file has been saved correctly.
    Log::debug($path . (Storage::disk('public')
        ->exists($path)? ' exists': 'does not exist'));

    $car->image_location = $path;
}

上传新图像后，我的storage/logs/laravel.log显示：

[2019-12-28 10:18:03] local.DEBUG: File has been found in request.  
[2019-12-28 10:18:03] local.DEBUG: images/WPMkdG56f4YXsd3IUJ3Ar1DbXF0QmtDz9bs0lKoI.gif exists
[2019-12-28 10:18:03] local.DEBUG: images/WPMkdG56f4YXsd3IUJ3Ar1DbXF0QmtDz9bs0lKoI.gif does not exist
[2019-12-28 10:18:03] local.DEBUG: images/s9RtTdFSv0Is8AgxDWX5c09zG8SyU987RVeC0di5.gif exists

更新表单中的新图像未更改
