这个不是bug，而且warning，当用$_GET[]或$_POST[]时不加isset之类判断的话，就会提示这个错误，Jones建议的解决方案完美解决这个问题：

<span style="font-family:Microsoft YaHei;font-size:14px;">function _get($str){    $val = !empty($_GET[$str]) ? $_GET[$str] : null;    return $val;}</span>

Copy after login

使用的时候，用法如下：

<span style="font-family:Microsoft YaHei;font-size:14px;">/** 计算总页数 */$sku = _get('sku');$warehouse = _get('warehouse');$supplier = _get('supplier');</span>

Copy after login
