Question

我的表单中有四个图像字段供不同用途使用。当我尝试在两个字段image_one和image_two上传图片时，有时会上传image_one，有时仅上传image_two

我的控制器代码：

if(Input::file('image_one'))
{
    $image_one = $post->storePostPicture($request->file('image_one'));

    if($image_one !== false) {
        $post->image_one = $image_one;
        $post->save();
    }
}


if(Input::file('image_two'))
{
    $image_two = $post->storePostPicture($request->file('image_two'));
    if($image_two !== false) {
        $post->image_two = $image_two;
        $post->save();
    }
}

我的storePostPicture函数在模型中：

public function storePostPicture($image) {
    if($image instanceof \Illuminate\Http\UploadedFile && $image->isValid() && $image->isReadable()) {
        $filePath = 'public/images/user' . DIRECTORY_SEPARATOR . 'post';
        if(!File::exists(storage_path('app' . DIRECTORY_SEPARATOR . $filePath))) {
            File::makeDirectory(storage_path('app' . DIRECTORY_SEPARATOR . $filePath), 0755, true);
        }
        $imageName = sha1(time().time()) . ".". $image->getClientOriginalExtension();
        if($image->storeAs($filePath, $imageName) !== false) {
            $path = "/storage/images/user/post/";
            return $path . DIRECTORY_SEPARATOR . $imageName;
        }
    }

    return false;
}

我做错了什么？

在您的迁移表中，请确保您已将所有图片字段设为可空：

$table->string('image_one')->nullable();
$table->string('image_two')->nullable();
...

此外，在收集完所有数据后保存您的帖子模型。

if(Input::file('image_one'))
{
    $image_one = $post->storePostPicture($request->file('image_one'));

    if($image_one !== false) {
        $post->image_one = $image_one;
    }
}


if(Input::file('image_two'))
{
    $image_two = $post->storePostPicture($request->file('image_two'));
    if($image_two !== false) {
        $post->image_two = $image_two;
    }
}  

$post->save(); //saving the post model here

Laravel：图片未上传
