Fetch image variable and display on input file - php

Question

I am trying to update an image and other data in a database, but when I update only text data, the image value becomes null or empty.
<form action="/admin/settings/why-us/update/{{$data->id}}" enctype="multipart/form-data" method="POST">
#csrf
<input type="text" class="form-control" name="title" value="{{$data->title}}">
<input type="file" class="form-control" value="{{$data->image}}" name="image">
<button type="submit" class="btn btn-success py-2 px-4 text-white">Update changes</button>
</form>
This a controller
public function updateWhyusPageSetting(Request $request,$id)
{
$title = $request->input('title');
$image = $image = $request->file('image');
dd($image);
if($request->hasFile('image')) {
$image = $request->file('image');
$filename = $image->getClientOriginalName();
$image->move(public_path('/frontend/images/'), $filename);
$image_upload = $request->file('image')->getClientOriginalName();
}
DB::table('features')
->where('id', $id)
->update([
'title' => $title,
'image' => $image_upload
]);
\Session::flash('flash_message', __('Why us data updated'));
\Session::flash('flash_type', 'success');
return redirect()->back();
}
When I input only the title, left out the image, and tried to dump using dd($image);, I got a null value.
When updating the image, it's getting updated very well database.
Now, my question is, how do I make sure the value is captured in the input file <input type="file" class="form-control" value="{{$data->image}}" name="image"> so that when I update other data, it also sends the image value. NB: value="{{$data->image}}" IS NOT capturing the data from database

Try this code
public function updateWhyusPageSetting(Request $request,$id){
$data = [];
$data['title'] = $request->input('title');
if($request->hasFile('image')) {
$image = $request->file('image');
$image->move(public_path('/frontend/images/'),$imageName = $image->hashName()); //hashName() will generate image name with extension
$data['image'] = $imageName; // here if user uploads an image, it will add to data array then add to DB.
}
DB::table('features')
->where('id', $id)
->update($data); // if a user uploaded an image will add. if not, a previous image will not change
\Session::flash('flash_message', __('Why us data updated'));
\Session::flash('flash_type', 'success');
return redirect()->back();
}
Please note you should delete the old images if you don't need anymore
you can use this to delete an old image if you want
(new Filesystem())->delete("full/path/with/image/name.jpg");
