执行网站程序时遇到：
Warning! Your PHP configuration limits the maximum number of fields allowed in a form 1000 for max_input_vars.
Please ask your hosting provider to increase this limit to 1139 at least, or you will have to edit the translation files.
查了一下，发现 PHP max_input_vars 是用来限制提交的表单数量的，从 PHP 5.3.9 开始。
修改 php.ini，找到 ;max_input_vars = 1000
修改为：
max_input_vars = 2500
数值看你需要！
