I Can't Work Out Where to Add together reCAPTCHA

This communication applies to everyone who's integrating reCAPTCHA -- irrespective of language.

Firstly you lot demand to place two hot spots in your code. These are the places where you'll be adding the reCAPTCHA calls.

Display reCAPTCHA: The first hot spot is the code that generates the form. Hopefully that's piece of cake enough to find (by looking for a <class> tag in your html) and you have been able to brandish the CAPTCHA on your grade.

Check reCAPTCHA: The second hot spot is the one that seems to cause people problems. Yous need to identify the lawmaking that handles course submission -- that is the code that runs when the user clicks on submit. It'south hard to generalize about what this code looks like but here are some clues that may help yous:

• if your course tin can ever display an mistake message, for instance if a required field is blank, wait for the code that generates that error bulletin.
• if your form places data in a database wait for code that does a SQL INSERT.
• if your form sends mail, search for the code that does that.

Form Already Has Validation

Life volition be easier if your course already has some validation logic (i.e. it handles invalid input from the user past displaying a message instead of performing whatever action information technology normally would). If that'due south the example and you can detect the code that does that you're nigh domicile gratis. If the course can display an error message search for the text of the error message within the code and you're certain to be close. Once you've plant the validation code y'all demand to add a telephone call to the check_answer function in addition to whatever other checks are at that place (electronic mail accost blank? age also young? etc.).

Form Has No Validation

If there's currently no validation logic for your form -- if clicking on submit always succeeds -- then you have a more than tricky problem. In that example yous'll have to add the reCAPTCHA validation code right before the existing form treatment code does whatever information technology does when the user submits. You'll likewise have to effigy out how to redisplay the form to give the user another attempt at the captcha. Unfortunately there'south no one stock answer to how you practise that. It depends entirely on the structure of the code you already have. If the existing code isn't too complex you may take luck posting it on the reCAPTCHA developer forum and asking for advice. (If you do post in that location, be sure to include enough data for others to help you; simply proverb "my code doesn't work" commonly doesn't yield skillful results.)

It'south Non Working! Aid!

Before doing annihilation else make sure you're using the right keys. Are your public and private keys swapped? Did y'all remember to put the private key in the form handler equally well as putting the public key in the grade?

Note that Mailhide uses dissimilar keys from the main class-based reCAPTCHA.

Be sure that your form uses the POST method, or else modify the reCAPTCHA form handler variables to GET instead of Postal service.

If reCAPTCHA was working and you suddenly get-go getting "An internal error occurred", did yous recently delete the Google account that yous used to sign upward for the keys? If so, register for new keys with an active business relationship and try those.

reCAPTCHA is Accepting Incorrect Words

Humans make errors and nosotros sympathize that. In reCAPTCHA nosotros use an avant-garde risk assay engine to decide whether the incoming request is from a human being or not. When we are highly confident that users are human being, nosotros allow them to make small mistakes.

No, I Mean *Totally* Incorrect Words

If reCAPTCHA is accepting any input whatsoever, you probably aren't correctly validating the reCAPTCHA respond with the API servers. That is, either: (ane) you are not correctly calling https://www.google.com/recaptcha/api/verify (or the equivalent function if you're using a plugin, such as recaptcha_check_answer in PHP), or (2) you are not taking the appropriate action given the response from our servers. Please come across the specific instructions that you lot used to install reCAPTCHA (whether it be through a plugin or not) to learn how to bank check whether the user entered the answer correctly.

My Users Are Starting To Get One Give-and-take Captchas

reCAPTCHA is not always about ii words. It is a examination to tell human and robots apart. In cases where we have high conviction that you are human, we volition serve you a much easier captcha (sample below). Our organization relies on your entire engagement with reCAPTCHA -- before, during, and later on solving it -- to make up one's mind if you pass or neglect the test, rather than on the solution alone.
