Thank you for the nice example. The method worked without any problems for me.
ReplyDeleteThanks a lot :)
ReplyDeleteit worked, thanks :D
ReplyDeletewhat a nice solution, thanks :)
ReplyDeleteAwesome. Thanks.
ReplyDeleteGood job. Thanks.
ReplyDeletebest answer, wish you the best.
ReplyDeleteThank you very much!
ReplyDeleteWhen you verify the second recaptcha, grecaptcha object doesn't fills up with the response, so you can't check if the recaptcha is submitted by doing grecaptcha.getResponse() to validate form before submitting. Any suggestions?
ReplyDeletehi david i am facing the same problem. did you get any solution?
DeleteI have the same issue, although it's with grecaptcha.reset() rather than getResponse. I use this with ajax requests so it would be nice to be able to reset the captcha if there was an error on the forum, especially considering the captcha doesn't have a refresh button like the old one did. Considering either using one recaptcha and attempting to display the same one in multiple locations or switch to AYAH since I have been able to use multiple instances at once before, and it still follows the simplicity approach except it's a drag and drop game rather than a simple checkbox.
DeleteFinally found the answer for this and it seems to be working. Basically when you use the render as above if you want to use the reset or getResponse function, all you need to do is pass the variable the render was assigned to to the first (only) parameter of the function.
DeleteFor example, grecaptcha.reset(recaptcha1); would reset the rendered recaptcha on the variable recaptcha1.
https://developers.google.com/recaptcha/docs/display#js_api
You can do like this: grecaptcha.getResponse(recaptcha2)
DeleteThis help me
Hi,
DeleteI have 2 recaptcha's in one page, first one is correctly validated from google and the second one is not, getting false as a response from google. i have added the below in client side and on submit, i added the code to validate the response from google(which is coming as false for 2nd recaptcha). Please help me out on this.Thanks in advance.
var recaptcha1;
var recaptcha2;
var myCallBack = function () {
recaptcha1 = grecaptcha.render('recaptcha1', {
'sitekey': 'site key', //Replace this with your Site key
'theme': 'light'
});
//grecaptcha.reset(recaptcha1);
//Render the recaptcha2 on the element with ID "recaptcha2"
recaptcha2 = grecaptcha.render('recaptcha2', {
'sitekey': 'site key', //Replace this with your Site key
'theme': 'dark'
});
};
Hi How do you fix this problem,i have same problem
Deletei have also same problem
DeleteI'm running Wordpress with a form in my common footer. On certain pages, I have two forms in which your integration works well. However, on the pages where there is only 1 form (footer), it breaks the reCaptcha from appearing. How do I allow it to work when there's only 1 form on the page?
ReplyDeleteThe error given on single form page is "Uncaught Type Error: Cannot read property 'children' of null" on recaptcha_en.js which is called in by the api.
DeleteThank you very much! I have been looking for a way to do this for several weeks and had given up until a spam storm forced me to search again. Took me about 5 minutes to test it and install it. Now I have another page that has 3 forms - each on a different tab - where I'll be using it next.
ReplyDeleteSuch a nice and straight forward solution, searching for over two hours for the solution. Great article and many many thanks for such a nice solution.
ReplyDeleteThanks & Regards,
Bhanu
nice...it works fine :) thank you :)
ReplyDeleteI have one question...how to make it required with javascript?
I've tried but only the first one displaying an alert when it's not checked...
Cool and simple, tanks!
ReplyDeletethank u , great post
ReplyDeleteAwesome.....
ReplyDeleteJust a heads-up, this does not work if you use Google's recommended and approved reCAPTCHA system.
ReplyDeleteYes it does, I use this with no issue.
DeleteThis comment has been removed by the author.
ReplyDeleteIt's Good but one problem is there when we put validation message if user leave recaptcha code ??
ReplyDeleteIs there another solution besides rendering both in the callback?
