Laravel如何保存for循环中的数据

Question

我有数据需要保存到数据库中。这是例子现在我的控制器：

public function saveRequest(Request $request){

$count = count($request->input('itemname'));
$purchase = new PrRequest;

    for ($i=0; $i<$count; $i++){
            $data[] = array(
            'pr_no' => $request->input('pr_no')[$i],    
            'pr_date' => $request->input('pr_date')[$i],
            'department' => $request->input('department')[$i],
            'remarks' => $request->input('remarks')[$i],
            'notes' => $request->input('notes')[$i],
            'requested_by' => $request->input('requested_by')[$i],
            'item_id' => $request->input('itemname')[$i],
            'qty' => $request->input('qty')[$i],
            'type' => $request->input('type')[$i],
            'uom' => $request->input('uom'),
            'pd_date' => $request->input('pd_date')[$i]
            );
        $purchase->fill($data[$i])->save(); 
    }
    return Response::json($data, 200, array(), JSON_PRETTY_PRINT);
}

点击保存按钮后出现错误。

ErrorException in helpers.php line 671:
preg_replace(): Parameter mismatch, pattern is a string while replacement is an array

有什么解决办法吗？提前谢谢你。

您每次迭代都在调用 fill，最好先构建数据然后再进行批量插入

for ($i=0; $i<$count; $i++){
        $data[] = array(
        'pr_no' => $request->input('pr_no')[$i],    
        'pr_date' => $request->input('pr_date')[$i],
        'department' => $request->input('department')[$i],
        'remarks' => $request->input('remarks')[$i],
        'notes' => $request->input('notes')[$i],
        'requested_by' => $request->input('requested_by')[$i],
        'item_id' => $request->input('itemname')[$i],
        'qty' => $request->input('qty')[$i],
        'type' => $request->input('type')[$i],
        'uom' => $request->input('uom'),
        'pd_date' => $request->input('pd_date')[$i]
        );
    $purchase->fill($data[$i])->save(); <-- remove this
}

DB::table(table name) -> insert($data); <-- this is better, one query.

希望对您有所帮助。
