Solve : Visual Verification Code in PHP? |
|
Answer» Dudez., can anyone give me an idea, how to generate a verification code in php. Because a lot of websites registration using a verification code before SUBMITTING the INPUTS.. And can anyone tell me, the importance of this verification code in a certain website?? Thanks!!! And I thinks., this stuff is using a random function.. just show me the sample codes huh!!Are you talking about CAPTCHAs? You will find lots of scripts >here<.I've already found one and it works..,JavaScript can do the same thing, and is probably EASIER because you don't need the GD library.Javascript cannot by definition do server-side validation. You could probably hack something up using Ajax, but such a scheme could be automatically bypassed relatively easily by the kind of people that CAPTCHAs are designed to THWART. I would not recommend a javascript approach. Just my opinion. |
