Customise Error Message

[Arkosoft]

Hi, I added some new fields to the registration form on my WHMCS, but I need to check if a field is empty or not before the registration process. There are some controls like if the name or surname is empty. How can I do to add other controls to this default ones?

I'm sorry, but I don't find other information about this.

You could just make the field 'required' - this would prevent the registration form from being submitted if the field is empty, for example:

 

<input type="text" name="name" required>

I was not clear, I'm sorry.

I added a popup menu and only if this popup is on a certain value, I must make the field 'required'.

An example: I choose "Company" from the popup and the field "VAT" must be "required", but if I choose "Freelance" the same field must not be "required".

 

Any idea for that?
