Insert array of arrays in Lumen with Eloquent ORM - php

Question

The POST request I'm sending looks like this:
{ "array1":
[
{"title":"my blogADD","description":"myblogdescriptionADD","status":1},
{"title":"my blogUPDATEDADD","description":"myblogdescriptionUPDATEDADD","status":1},
{"title":"my blog33ADD","description":"myblogdescription33ADD","status":1}
]
}
Its JSON format, headers have been set.
The controller code which gets the request looks like this:
public function create(Request $request){
$this->validate($request, [
'array1' => 'present|array',
'array1.*.title' => 'required',
'array1.*.description' => 'required'
]);
$data = $request->getContent();
$data = json_decode($data, true);
//dd($data);
Article::insert($data);
}
Now, I've looked into multiple questions and answers on SO on this problem, and the findings are somehow contradictory.
Model::insert() shall be able to insert multiple rows in ONE call.
However, as you can see, this hasn't worked for me so far.
Model::create() is only able to create one new row, but I found solutions which use loops to iterate over the arrays. I would very very much like to avoid such a solution, unless someone can FOR CERTAIN tell me that there is no other, simple solution. Because I very much believe that there must be one.
When I input the json_decoded ARRAY then I get the response that an Array to String conversion is hindering the process.
When I input the mere JSON-String, then I get the error:
"Argument 1 passed to Illuminate\Database\Query\Builder::insert() must be of the type array, string given, called in E:\LumenTut\firstTut\vendor\illuminate\database\Eloquent\Builder.php on line 1350"
Well, here are two links to SO posts which, in my opinion, basically dealt with the same problem. But somehow it seems they could solve it and I can't, so I wonder what I am missing:

For completeness, here is the full Code of ArticleController.php:
EDIT:
<?php
namespace App\Http\Controllers;
//use Validator;
use App\Article;
use Illuminate\Http\Request;
class ArticleController extends Controller
{
/**
* Create a new controller instance.
*
* #return void
*/
public function __construct()
{
//
}
//
public function showAllArticles(){
return response()->json(Article::get(['title', 'description', 'status'])); // ::get([]) spezifiziert die zu referenzierenden Attribute
// ::all() referenziert alle Attribute einer Tabelle/Relation
}
public function showOneArticle($id){
return response()->json(Article::find($id));
}
public function create(Request $request){
$this->validate($request, [
'array1' => 'present|array',
'array1.*.title' => 'required',
'array1.*.description' => 'required'
]);
$data = $request->getContent();
//$data = json_decode($data, true);
//dd($data);
Article::insert($data);
}
public function update($id, Request $request){
$this->validate($request, [
'title' => 'required',
'description' => 'required'
]);
$article = Article::findOrFail($id);
$article->update($request->all());
return response()->json($article, 200);
}
public function delete($id, Request $request){
Article::findOrFail($id)->delete();
return response('Deleted Successfully', 200);
}
public function resetRecords(Request $request){
Article::where('id', '>', 2)->delete();
}
}

Answer 1

From the looks of it, it feels like you are trying to push array1 directly in your table, whereas you need to push the content of it so maybe try like this, in your controller code:
$requestData = $request->all();//this will give you an array with key array1
$data = $requestData['array1'];//this will give you data you want to insert
Article::insert($data);

Answer 2

Based on the error. You are not passing an array. You can change the $data with
$data = $request->all();
$request->all() returns the data from the post in array.
You can rewrite your create method with the following.
public function create(Request $request){
$request->validate([
'array1' => 'present|array',
'array1.*.title' => 'required',
'array1.*.description' => 'required'
]);
$data = $request->all();
Article::insert($data['array1']);
}
