storing uploaded image into database laravel
提问by blastme
I am having trouble uploading my image into database, everytime I try to upload it, the data send into the database is empty but my local disk is able to store the image and I don't know what to do. I think I might have done something wrong in the controller part
我在将图像上传到数据库时遇到问题，每次尝试上传时，发送到数据库的数据为空，但我的本地磁盘能够存储图像，我不知道该怎么做。我想我可能在控制器部分做错了什么
Controller:
控制器：
public function store1(Request $request){
$this->validate($request, [
'file' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
if ($request->hasFile('file')) {
$image = $request->file('file');
$name = $image->getClientOriginalName();
$size = $image->getClientSize();
$destinationPath = public_path('/images');
$image->move($destinationPath, $name);
$userImage = new UserImage;
$userImage->name = $name;
$userImage->size = $size;
//dd($userImage);
$userImage->save;
}
table that I wanted to upload to:
我想上传到的表：
Schema::create('user_images', function (Blueprint $table) {
$table->increments('id');
$table->string('name');
$table->string('size');
$table->integer('user_id');
$table->timestamps();
});

In your posted code, you forgot setting the data for user_id. As I can see in your schema, it is not nullable so it should have a data.
在您发布的代码中，您忘记设置user_id. 正如我在您的架构中看到的那样，它不可为空，因此它应该有一个数据。
Also, can you try putting ()in your save like so :
另外，您可以尝试()像这样保存保存吗：
$userImage->save();
