Hello everyone,

I'm trying to combine 3 form input fields into 1 that is hidden (Date of Birth). The input fields are DOB-MM, DOB-DD, and DOB-YYYY and the hidden field is DOB which will store the Date of Birth in the following format 'YYYY-MM-DD'. Unfortunately I don't know javascript so I hope someone can help me write a quick script that will combine these 3 fields and arrange them in the format required.

Thank you in advance!

Hello RajaRajan.R,

Thank you for your reply. One quick question about your code. Should the value of the line below be test or text?

<input type="hidden" size="10" name="dob" value="test">




Dont worry about that, it is "test" only it is a default value displayed in the hidden field, you can also leave it simply with "". We change the "test" to "1998-5-12" in javascript using that name of the hidden field.
