Google Recaptcha验证不适用于jQuery Form Validator

Question

My Problem :

I have a registration form as a view in Codeigniter for which I have performed client side validation using Jquery Form validation. The form validation is working perfectly fine for me .

However , I have the following problems with this form :

1.Recaptcha validation : I have a linking checkbox in this form which allows the user to fill in some more details and upload his company logo . When the user clicks on this checkbox , the jquery code simply adds a text box and a file upload option to upload the company logo . (please see my jquery code to add the linking elements when the user checks the checkbox)

If the user does not click on this checkbox , and fills in all the input fields without selecting the recaptcha validation ,and presses submit button, the jquery form validator throws an error message and prompts the user to select the recpatcha validation .

However when , the user clicks on the checkbox for linking option , fills in all the input fields without selecting the recaptcha validation and presses submit button , the page simply refreshes without giving an error message . The jquery form validator should ideally throw an error message and disallow the page to submitted if the user doesnt select the recaptcha validation .

The problem arises only when the user checks the checkbox for linking.

2.Terms and conditions checkbox validation :

If the user does not click on the linking checkbox option , fills in all the input fields without clicking on this checkbox ,and presses submit button, the jquery form validator throws an error message and prompts the user to select the terms and conditions checkbox .

However,when the user checks the linking checkbox , fills in all the input fields including recaptcha validation , but doesn't check the terms and conditions checkbox , and presses submit , the page simply refreshes without throwing an error message . The jquery form validator should ideally throw an error prompting the user to check the terms and conditions checkbox .

Any help on this issue will be appreciated .

My code :

Registration form :

.error{color:red;font-Style:Arial;font-Size:12px;};

My Research : I have gone through the following questions on Stack Overflow :

1. reCaptcha v2 in conjunction with jQuery-Form-Validator

2. New reCaptcha with jQuery Validation Plugin

3. how to test Recaptcha with jQuery Validate plugin

Answer 1

Solution :

I found that the extension method of jquery form validator,for file upload , was the root cause of the issue . When it was being used , the form validator was not throwing an error when terms and conditions checkbox and/or google recaptcha validation was not being checked .

When I replaced this method with a custom method fileextension using add method in Jquery form validator , the issue was resolved . The form was getting validated and was throwing an error when terms and conditions checkbox and/or google recaptcha validation was not being checked.

My Final Jquery code:

$("form[name='frmempsignup']").validate(
        {
            ignore: ".ignore",
            rules:
