How to upload a mobile captured image into laravel in base64 format?

Its just a string. Just make sure the column is large enough in the database.

@snapey Yeah thats clear, but I have a problem with the upload

This is a snippet of my view:

<form method="post" action="{{url('upload')}}" enctype="multipart/form-data">
      {{csrf_field()}}
        <div class="input-group control-group increment" >
          <input type="file" name="image" accept="image/*" capture>
        </div>
        <button type="submit" class="btn btn-primary" style="margin-top:10px">Submit</button>
</form>        

And this is my controller:

    public function store(Request $request)
    {
        $this->validate($request, [
                'image' => 'required'
        ]);

        $pic= new Picture();
        $pic->image=$request->image;
        $pic->save();
        
        return back()->with('success', '');
    }

I am getting the error that the picture input is not filled... So what can I do to fix this?

Check out one of the tutorials for file upload.

As this is multi-part form data, you need to use the $request->file() helper

@snapey thanks for the link

But if I try to upload the photo, I am getting an error from laravel, which says that image can not be null (in database) which indicates that there is no photo which was uploaded or not?

In your Model do you have protected $guarded = []; ?

@chrisgrim No

Why don't you upload like any other image and just store the image name in the database.

There's nothing special about an image taken from a mobile.

Optimize your images for the web.

Often when I can't get my requests through it's because of a mass assignment issue. Try adding protected $guarded = [];

@jlrdw this is a special requirement which is definitely not arguably cause this website is just for upload, it will not display any images. The data which was uploaded will run through different processes (the website is just the input-gateway) and will not be stored on the website, why they must be stored as base64.

what does your controller look like now.

dd($request()->all) in your controller to check what has been uploaded.

Also, in the controller, substitute the upload for a simple string and check it gets persisted in the database
