Question

我从我的服务器上传输了一个文件，该文件在互联网上正常运行到我的本地计算机。

它为我的变量抛出了很多未定义的索引，

请告诉我可能是什么问题，因为它在互联网上运行良好，而不是在本地工作

下面是错误和相关代码

“注意：未定义的索引：加入 /Users/mgltd/Sites/reacheasy/youraccount.php第27行注意：未定义的索引：Sname in /Users/mgltd/Sites/reacheasy/youraccount.php 第30行注意：未定义的索引：Pname in 第31行/Users/mgltd/Sites/reacheasy/youraccount.php注意：未定义索引：Pidno in /Users/mgltd/Sites/reacheasy/youraccount.php 第32行注意：未定义的索引：Psize in 第33行/Users/mgltd/Sites/reacheasy/youraccount.php注意：未定义的索引：Pcolour in 第34行/Users/mgltd/Sites/reacheasy/youraccount.php注意：未定义的索引：Pquantity in /Users/mgltd/Sites/reacheasy/youraccount.php第35行注意：未定义的索引：Weblink in /Users/mgltd/Sites/reacheasy/youraccount.php第36行注意：未定义的索引：/Users/mgltd/Sites/reacheasy/youraccount.php中的价格第37行注意：未定义索引：注释第38行/Users/mgltd/Sites/reacheasy/youraccount.php警告： date（）：依赖系统的时区设置是不安全的。您必需使用date.timezone设置或 date_default_timezone_set（）函数。如果您使用其中任何一个方法，你最有可能仍然得到这个警告拼写错误的时区标识符。我们选择了“欧洲/伦敦” 'BST / 1.0 / DST'改为/Users/mgltd/Sites/reacheasy/youraccount.php 在第39行“

Answer 1

我会将php-block包装在if：

的顶部

if( isset($_POST['submit']) ){ 

    // Rest of the code that populates the variables and so on

}

这样可以确保您不会尝试操作远在那里的值。：）

Answer 2

看起来$_POST超全球没有被填充（你有没有检查过这个？），或者至少它不包含你的想法。

您的代码似乎在没有检查的情况下假设POST值。

运行print_r($_POST) - 它是否包含正确的数据？

未定义的索引
