Array to string conversion error when multiple file upload in Laravel 5.8.38 - laravel

Question

I have an Array to string conversion error, when trying to realize multiple upload files function in Laravel 5.8.38
Cant find any decision about it
In blade form I have simple thing:
<form class="form-horizontal" action="{{route('admin.estates.store')}}" method="post" enctype="multipart/form-data">
{{ csrf_field() }}
<label for="estate_image" class="mt-4">Images</label>
<input type="file" name="estate_image[]" multiple>
<input class="btn btn-primary" type="submit" value="Сохранить">
<input type="hidden" name="created_by" value="{{Auth::id()}}">
</form>
In store function I have:
The function creates an estate(one property). If user adds some images for it, we adds this images in local path and adds them in database
if I comment $estate = Estate::create($request->all()); it works fine
but in this case estate doesnt adds in database
public function store(Request $request)
{
$estate = Estate::create($request->all());
if($request->hasFile('estate_image')) {
foreach ($request->file('estate_image') as $image) {
// do some image resize and store it on local path
$filename = time() . '.' . $image->getClientOriginalExtension();
$location = public_path('images\\' . $filename);
Image::make($image)->resize(800, 400)->save($location);
// add image info in database
$estateimage = new EstateImages();
$estateimage->image_path = $location;
$estateimage->image_alt = 'testalt';
$estateimage->save();
}
}
}
Am array I have from input
array:5 [▼
"name" => array:2 [▼
0 => "image1.jpg"
1 => "image2.jpg"
]
"type" => array:2 [▼
0 => "image/jpeg"
1 => "image/jpeg"
]
"tmp_name" => array:2 [▼
0 => "C:\OSPanel\userdata\php_upload\phpCB51.tmp"
1 => "C:\OSPanel\userdata\php_upload\phpCB52.tmp"
]
"error" => array:2 [▼
0 => 0
1 => 0
]
"size" => array:2 [▼
0 => 164808
1 => 58217
]
]
As understand, foreach doesnt start, but dont understand why (tried to delete all code in foreach, and leave there just simple echo 'Hello!'; , have the same error.
Saw the same problems in StackOverflow, but any of it helped me...

Answer 1

The problem was in first line
$estate = Estate::create($request->all());
So, from blade I receive a name="estate_image[] data which is an array, and Laravel tried to adds an array in database cell. In database cell cold be added just string value and through that, I had that error.
Solve it, by deleting this column from database and deleting this from $fillable variable in main model.
Quite stupid and easy thing from me, but hope, this answer helps someone. :-)
