错误一:thinkphp5.1 致命错误:
Call to a member function validate() on null
注意表单添加:enctype="multipart/form-data"
注意二:上传图片要进行try,不然要报警告没有上传文件file
try{
$file = request()->file('img');
$info = $file->validate(['ext'=>'jpg,png,gif'])->move( '../public/uploads/');
if($info){
$data['img'] = str_replace("\\","/",$info->getSaveName());
}else{
$res = $file->getError();
return $this->sendError($res);
}
}catch (\Exception $e) {
}
