PHP验证码验证码(PHP Verification Codes CAPTCHA)
我运行一个游戏网站,所以我有很多用户登录,他们可以每两分钟做一次特定的事情。
我有一个CAPTCHA系统,对于某些事情,它总是会要求一个代码,对于其他的事情,它会每10分钟询问一次。
我有一些玩家在Opera上使用自动提交功能,而我的CAPTCHA系统确实阻止了他们。
我的问题是,我如何尽量减少要求代码的次数,但仍然停止使用此自动提交的人员?
I run a game website so I have many users logged in and they can do certain things once every two minutes.
I have a CAPTCHA system in places, and for some things it will always ask for a code, and for other things, it will ask once every 10 minutes.
I have had some players use the auto submit feature on Opera, and my CAPTCHA system does stop them.
My question is, how can I minimise the amount of times I am asking for a code, but still stop people using this auto-submit?
