以下内容适用于一些有类似问题的用户：

尝试增加max_input_vars 变量输入php.ini. PHP版本中引入了此变量5.3.9 默认值为1000.

您可以在PHP文档中了解更多信息：

一零三e> 可以接受多少输入变量（限制分别应用于$\\u GET、$\\u POST和$\\u COOKIE superglobal）。使用此指令可以降低使用哈希冲突的拒绝服务攻击的可能性。

您可以尝试将其增加到1500 或2000.

估计值：

使用下面的数据，我们可以尝试估计在给定一定数量的菜单项的情况下，当我们按下Save Menu 按钮

似乎是：

"number of POST variables" = 11 * "number of menu items" + 9

相当于线路：

y=11x+9

然后我们可以构建下表：

在你的情况下，如果你需要保存100 菜单项，您需要发送1109 发布变量max_input_vars 必须至少为1109.

类似地，当我们将项目添加到菜单时（通过Ajax POST）

我们得到

"number of POST variables" = 10 * "number of menu items" + 3

哪一行：

y=10x+3

相应的数据表为：

当我们添加10 菜单项，我们发送103 POST变量。

数据：

仅显示$_POST 仅使用保存菜单时的数据5 项目：
