How to Verify whether a Robot is Entering Information

由 你说的曾经没有我的故事 提交于 2019-12-01 22:13:09
I have a web form which the users fill and the info send to server and stored on a database. I am worried that Robots might just fill in the form and I will end up with a database full of useless records. How can I prevent Robots from filling in my forms? I am thinking maybe something like Stackoverflow's robot detection, where if it thinks you are a robot, it asks you to verify that you are not. Is there a server-side API in Perl, Java or PHP? There are several solutions. Use a CAPTCHA. SO uses reCAPTCHA as far as I know. Add an extra field to your form and hide it with CSS (display:none). A

In that popup he can see registration form with email field, password field, and CAPTCHA (default Yii captcha). So, my model for user's registration is User. There is a validation rule: array('code', 'captcha', 'allowEmpty'=>!Yii::app()->user->isGuest), My controller, where all user's actions are, is User (url: site.url/user/) and I added

Enable Captcha after several login failure - How to implement this?

由 ▼魔方 西西 提交于 2019-12-01 18:04:32
I'm working on an auth system with login failure. If the user fails to login, the attempts number in database is incremented and if a defined limit is reached, PHP sets a session captcha variable to true. So when the user (or spam bot) gets the login page again, a captcha form is shown thanks to the session variable But since Spam bots could eventually delete the session cookie and retry, this may be not effective. Should I use a database solution instead ? How would you implement this (with/or without the database) ? Timm Spam bots can get around session restrictions fairly easily, so it

“Could not open socket”

由 橙三吉。 提交于 2019-12-01 06:02:19
How do I alleviate the "Could not open socket" error that is happening on my site? I have troubleshot that it is CAPTCHA (I'm using reCAPTCHA ). It is only displaying this error on the two pages where I use reCAPTCHA. I have been generating new sets of keys, and sometimes it works and sometimes it does not. For example, it worked on Safari and sometimes not, but on Firefox , and vice versa, and it worked for me and not for one of my partners and vice versa. How can I fix this problem? Could it be that my server is having trouble doing the fsocketopen command? If so, how do I fix that? Could it
