Unable to submit binary image into database in laravel - php

Question

I am trying to submit an image into the database but I keep getting this error: Type error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::save() must be an instance of Illuminate\Database\Eloquent\Model, null given, called in C:\xampp\htdocs\Evaluation\app\Http\Controllers\ImageController.php on line 24.
I checked with other questions in StackOverflow and mostly they said it was the fault of the saving part where they put something like this, $post but I have checked and there is nothing wrong with it. The relationship doesn't seem to have any problem as well but why is it still not working? The error also return me a null when I upload image. The null is returning at the part here, $UserImage = $request->input('UserImage'); So could my problem be in image1.blade.php?
ImageController:
public function test(personal_info $user){
return view('image1',compact('user'));
}
public function test1(Request $request){
$UserImage = new Image;
$personal_info = new personal_info;
$UserImage = $request->input('UserImage');
$id = $request->user_id;
$id = personal_info::find($id);
$id->Images()->save($UserImage);
return redirect('/summary');
}
image1.blade.php (where i submit the form)
<form class="form-horizontal" method="post" action="{{ url('/Upload')}}" enctype="multipart/form-data">
{{ csrf_field() }}
<input type="hidden" name="user_id" value="{{$user->id}}">
<div class="form-group">
<label for="imageInput" class="control-label col-sm-3">Upload Image</label>
<div class="col-sm-9">
<input type="file" name="UserImage">
</div>
</div>
<div class="form-group">
<div class="col-md-6-offset-2" style="padding-left: 30px">
<input type="submit" class="btn btn-primary" value="Save">
</div>
</div>
</form>
Image.php:
public function personal_infos() {
return $this->belongsTo('App\personal_info', 'user_id', 'id');
}
personal_info.php:
public function Images() {
return $this->hasOne('App\Image','user_id');
}

Answer 1

public function test1(Request $request)
{
// make new instance of Image Model
$imageModel = new Image;
// find personal_info Model by id
$personal_info = personal_info::findOrFail($request->input('user_id'));
// UploadedFile
$image = $request->file('UserImage');
// get the file contents?
$imageModel->content = ...
// save the relationships, pass a model instance to `save`
$personal_info->Images()->save($imageModel);
return redirect('/summary');
}
