Laravel 9在图像上传时调用字符串上的成员函数storeAs()

Question

下面的函数在我的create方法中工作，是我的另一个post的解决方案。我似乎无法在我的update方法中工作--一个Call to a member function storeAs() on string错误持续存在。错误屏幕突出显示foreach循环。

edit.php

public function updateTentry($id)
{
    $tentry = Tentry::find($id);

    $images = [
        'image_plant_general',
        'image_plant_closeup',
        'image_fruit_in_plant',
        'image_fruit_in_plant_closeup',
        'image_fruit_in_harvest_single',
        'image_fruit_in_harvest_group'
    ];

    $data = [
        'trial_id' => $this->trial->id,
        'pt_plant_vigor' => $this->pt_plant_vigor,
        'pt_plant_color' => $this->pt_plant_color,
        'pt_plant_growth' => $this->pt_plant_growth,
        ... 
        // more variables
    ];

    foreach ($images as $image) {
        $data[$image] = $this->{$image}?->storeAs($this->evaluation->id, $this->trial->id . '_' . $this->tentry->id . '_' . $image . '_' . Carbon::now()->toDateString() . '.' . $this->{$image}->getClientOriginalExtension(), 'trial-entry-photos');
    }

    $tentry->update($data);

    session()->flash('success', 'Tentry Updated Successfully');

    return redirect()->route('tentry.edit', [$this->evaluation->id, $this->trial->id, $tentry->id]);
}

存储和存储函数可在UploadedFile上使用。

$request->file()返回IlluminateHttp\UploadedFile的一个实例，其中存在store和storeAs()方法。

因此，您需要更改以下内容

foreach ($images as $image) {
        $data[$image] = $this->{$image}?->storeAs($this->evaluation->id, $this->trial->id . '_' . $this->tentry->id . '_' . $image . '_' . Carbon::now()->toDateString() . '.' . $this->{$image}->getClientOriginalExtension(), 'trial-entry-photos');
    }

至

foreach ($images as $image) {
    if(request()->hasFile($image) && request()->file($image)->isValid()) {
        $uploadedFile = request()->file($image);
        $data[$image] = $uploadedFile->storeAs(
            /** path where the uploaded file is to be stored */
            $this->evaluation->id, 

            /** Filename by which the uploaded file must be stored */
            $this->trial->id . '_' . $this->tentry->id . '_' . $image . '_' . Carbon::now()->toDateString() . '.' . $uploadedFile->getClientOriginalExtension(),

            /** name of one of the disks defined in the config/filesystems.php */
            'trial-entry-photos');
    }
}
