当我尝试上传图片时,我不断遇到以下错误。有谁知道如何解决这个问题?我对下一步做什么感到困惑。
对成员函数getClientOriginalName()的调用为null

$new_name_Two,

if ($query) {
return redirect()->back()->with('messages', 'Data Is Successfully Inserted');
}
}
return redirect()->back();
}
据我所知$request->file('select_file_Two');
返回null
;这意味着很可能没有为名称为select_file_Two
的输入选择任何文件,请确保名称使用相同的大小写而不是select_file_two
。如果需要所有文件,您可以像这样将required
添加到验证器中>
`require|image|mimes:jpeg,png,jpg,gif,svg|max:2048`
或者如果是可选的,您可以像这样检查文件是否存在
if(!is_null($select_file_one)){ $new_name_one = rand() . '.' . $select_file_one->getClientOriginalName(); $select_file_one->move(public_path('projects'), $new_name_one); }
并熟练处理所有未发送的文件。
这里还要注意的是,您正在使用rand()生成新名称,这可能会及时覆盖文件。我建议像这样添加时间戳记
use Carbon\Carbon;
$name = rand() . '_' . now()->timestamp . '.' . $image->getClientOriginalExtension();
如果您的代码正常,这似乎是这样,大多数时候您是html表单。查看您的表单,查看表单标签中是否包含enctype="multipart/form-data"
,否则将不会发送文件。孔表单部分应如下所示:
