Question

there is no problem when I do create new data. everything is ok including uploading image. My image inserted to public/image directory.
But when i try editing or updating, i have a problem. my image that should be inserted to public/image not work on update function.
the controller is below
public function store(Request $request)
{
$request->validate([
'name' => 'required',
'sequence' => 'required',
'image' => 'required|image|max:2048',
'link' => 'required',
'status' => 'required',
]);
$image = $request->file('image');
$new_name = $request->name .rand(). '.' . $image->getClientOriginalExtension();
$image->move(public_path('images'), $new_name);
$form_data = array(
'name' => $request->name,
'sequence' => $request->sequence,
'image' => $new_name,
'link' => $request->link,
'status' => $request->status,
);
Banner::create($form_data);
return redirect()->route('banner.index');
}
public function update(Request $request, Banner $banner)
{
$image_name = $request->hidden_image;
$image = $request->file('image');
if($image != ''){
$request->validate([
'name' => 'required',
'sequence' => 'required',
'image' => 'image|max:2048',
'link' => 'required',
'status' => 'required',
]);
$image_name = $request->name .rand(). '.' . $image->getClientOriginalExtension();
$image->move(public_path('images'), $image_name);
}
else{
$request->validate([
'name' => 'required',
'sequence' => 'required',
'link' => 'required',
'status' => 'required',
]);
}
$form_data = array(
'name' => $request->name,
'sequence' => $request->sequence,
'image' => $image_name,
'link' => $request->link,
'status' => $request->status,
);
Banner::whereId($banner)->update($form_data);
return redirect()->route('banner.index');
}

<form action="{{ route('banner.update',$banner->id) }}" method="POST">
#csrf
#method('PUT')
<div class="row" style="margin-top: 10px">

Answer 1

your form is missing enctype attribute and so no file is passing with the form. add that attribute and everything will work.
<form action="{{ route('banner.update',$banner->id) }}" method="POST" enctype="multipart/form-data">
