$task->delete();
return redirect('/');
}
else
{
$task->description = Request::get('description');
$task->save();
return redirect('/');
}
}
public function upload(Request $request, Task $task)
{
if(isset($_POST['delete'])) {
$task->delete();
return redirect('/');
}
else
{
$task->image = Request::get('image');
$task->save();
return redirect('/');
}
}
edit.blade.php
<div class="container">
<h1>Edit the Task</h1>
<form method="POST" action="/task/{{ $task->id }}">
<div class="form-group">
<textarea name="description" class="form-control">{{$task->description }}</textarea>
</div>
<form action="{{ URL::to('upload') }}" method="post" enctype="multipart/form-data">
<label>Select image to upload:</label>
<input class="btn btn-primary" type="file" name="file" id="file">
<input class="btn btn-primary" type="submit" value="Insert" name="insert" enctype="multipart/form-data">
<input class="btn btn-primary" type="hidden" value="{{ csrf_token() }}" name="_token">
<img class="user_avatar" src="{{url('public/uploads/test.jpg')}}">
</form>
<div class="form-group">
<button type="submit" name="update" class="btn btn-primary">Update task</button>
</div>
<div class="form-group">
<button type="submit" name="update" class="btn btn-primary">Update task</button>

Answer 1

Try this
public function upload(Request $request, Task $task)
{
if(isset($_POST['delete'])) {
$task->delete();
return redirect('/');
}
else
{
$task->image = \Storage::disk('public')->put('image', $request->file('image'));
$task->save();
return redirect('/');
}
}
and
filesystems.php
inside
'public' => [
'driver' => 'local',
'root' => public_path() . '/uploads',
'url' => env('APP_URL').'/uploads',
'visibility' => 'public',
],
inside blade
<input class="btn btn-primary" type="file" name="image" id="file">
change name="image" then only you can get $request->file('image')

Answer 2

Use this to same image directly to db in BLOB field
$task->image = request('image')->encode('jpg', 80);
$task->save();
You can update the variables as suitable to you but the solution is in encode
You can encode your image first like this
$b64 = base64_encode(request('image'));

Answer 3

you can not save image in database, you must move image to a folder and save address it in database and type column image must be varchar text.
change code to :
public function storeTask()
{
$task = new Task();
$task->name = request('name');
$task->description = request('description');
$image = request->file('image');
$extention = $image->getClientOriginalExtension();
$name = rand(1000, 9999) '.' . $extention;
$path = public_path() . '/images/' . $name;
$image->move($path);
$task->image = $path;
$task->save();
return redirect('/task');
}

Answer 4

Try the following code:
$path = $request->file('image')->getRealPath();
$image = file_get_contents($path);
$base64 = base64_encode($image);
$task->image = $base64;
$task->save();
