Laravel 将数据放入数组

我在做一些基于商家的电子商务网站。提交订单时出现问题。问题是，当我选择同一个商户时，时间订单将被成功存储，但当我从不同的商户中选择多个产品时，我的功能会出现未定义偏移的错误：1。这是我的功能

public function post_order(){
    $data = Input::all();
    $count = count($data['invoice_no']);
    $order = array();
    for($i=0; $i<$count; $i++){
        if(!empty($data['invoice_no'][$i])){
            array_push($order, array(
                'order_no'          => $data['order_no'][$i],
                'invoice_prefix'    => $data['invoice_prefix'][$i],

到目前为止，您做了什么来调试它呢？哦，孩子DB:：table，我们又见面了。你没有使用任何模型吗？在$id上使用loop而不是foreach的原因是什么？是否可以将$id更改为$orderCollection中有意义的内容？当您执行dd$id时会发生什么？
