Call to a member function store() on null - laravel 5.4 - laravel

Question

I'm trying to upload an image though everytime I submit it's returning that the store() on null error. I've set the form to enctype="multipart/form-data" which hasn't helped.
Can anyone point me in the right direction?
Thanks.
Function inside the controller
public function store(Request $request){
$file = $request->file('imgUpload1')->store('images');
return back();
}
Form below:
<form action="/imgupload" method="POST" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label for="imgUpload1">File input</label>
<input type="file" id="imgUpload1">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>

Answer 1

I had the same issue what I did to fix is in the opening form tag add enctype="multipart/form-data" that should fix it. Without it laravel would not understand the file.
like:
<form method="POST" enctype="multipart/form-data" name="formName">

Answer 2

The data is always fetched with name attribute which is missing in your form input
Change
<input type="file" id="imgUpload1">
to
<input type="file" id="imgUpload1" name = "imgUpload1">
and do some validation in the controller side like this
$val = Validator:make($request->all, [
'imgUpload1' => 'required',
]);
if($val->fails()) {
return redirect()->back()->with(['message' => 'No file received']);
}
else {
$file = $request->file('imgUpload1')->store('images');
return redirect()->back();
}

Answer 3

you need add this code in your controller
if ($request->file('imgUpload1') == null) {
$file = "";
}else{
$file = $request->file('imgUpload1')->store('images');
}

Answer 4

you are getting error because your store function is not seeing the file from your request from the input tag so to fix this set the "name" just I have done below
<form action="/imgupload" method="POST" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group">
<label for="imgUpload1">File input</label>
<input type="file" id="imgUpload1" name="imgUpload1">
</div>
<button type="submit" class="btn btn-primary">Submit</button>
</form>
