Question

我正在编写一个脚本以将新数据插入Database，但我一直收到错误： -

注意：未定义的索引：priceBig in 第12行的C：\ xampp \ htdocs \ demo \ admin \ add.php

我错过了什么吗？

如何修复此错误？任何帮助都会很棒。谢谢

Answer 1

使用这种方式：

>>> x_flat = [i for sub_l in x for i in sub_l]
>>> final_list = []
>>> for number in x_flat:
        if number not in final_list:
            finalList.append(number)

Answer 2

$_REQUEST['priceBig']根本没有定义。

如果写一个空字段或只是NULL表没问题，可以通过检查$_REQUEST['priceBig']是否设置或为空来解决这个问题，然后将其定义为NULL：

if(!isset($_REQUEST['priceBig'])){
    $priceBig = NULL;
}else{
    $priceBig = $_REQUEST['priceBig'];
}

获取错误插入新数据时查询为空
