ErrorException Array to string conversion Laravel

Question

这是我在控制器中的代码。 我希望将多个数据插入到数据库中，但是Array有问题：

public function postCreate(Request $request)
{
$data = $request->all();
$lastid = Tr_header::create($data)->id;
if (count($request->id_product) > 0)
{
foreach($request->id_product as $item => $value)
$datax = array(
'id_tr_header' => $lastid,
'id_product' => $request->id_product[$item],
'qty' => $request->qty[$item],
'date_kembali' => $request->date_kembali[$item],
'information' => $request->information[$item],
);
Tr_detail::insert($datax);
}
return redirect()->back();

Answer 1

如果要一次插入多行，请尝试以下操作：

{
$data = $request->all();
$lastid = Tr_header::create($data)->id;
if (count($request->id_product) > 0)
{
$datax = [];
foreach($request->id_product as $item => $value)
array_push($datax ,[
'id_tr_header' => $lastid,
'id_product' => $request->id_product[$item],
'qty' => $request->qty[$item],
'date_kembali' => $request->date_kembali[$item],
'information' => $request->information[$item],
]);
Tr_detail::insert($datax);
}
return redirect()->back();

你正在重写你的$datax变量，你需要创建一个数组数组来传递给你的insert()函数：

public function postCreate(Request $request)
{
$data = $request->all();
$lastid = Tr_header::create($data)->id;
if (count($request->id_product) > 0) {
$datax = [];
foreach ($request->id_product as $item => $value)
$datax[] = array(
'id_tr_header' => $lastid,
'id_product' => $request->id_product[$item],
'qty' => $request->qty[$item],
'date_kembali' => $request->date_kembali[$item],
'information' => $request->information[$item],
);
Tr_detail::insert($datax);
}
return redirect()->back();
}
