Registration and custom fields

Hi,

So i would like to add Last name when user register. Which i need between first name and login name.
I have created custom field with user table but it will display on the bottom so not good. So added this in user/regsitration view file:

<div class="hikashop_registration_surname_line form-group" id="hikashop_registration_surname_line">
    <div class="key col-sm-3 control-label">
			<label for="surname">
				<?php echo JText::_( 'HIKA_USER_SURNAME' ); ?> *
			</label>
		</div>
			<div class="col-sm-9">
				<input type="text" name="data[user][surname]" id="surname" value="<?php echo $this->escape($this->mainUser->get( 'surname' ));?>" class="inputbox required" maxlength="50" />
				
			</div>

Hi,

I will try to explain it more clearly. I need field in joomla user registration and hikashop user registration called "Surname" I need it to act like default "Name" field. I use joomla registration and in checkout hikashop registration. So if someone register first with joomla registration. Name, login name, password, email are synchronized with hikashop. Or if someone goes to checkout he will be asked to register with hikashop registration and all entered data will be synchronized with joomla user.
So I creaded field in joomla. I added this code to /components/com_users/models/forms/registration.xml:

<field name="surname" type="text"
		        class="inputbox"
			description="COM_USERS_REGISTER_SURNAME_DESC"
			label="COM_USERS_REGISTER_SURNAME_LABEL"
			required="true"
			size="30"
		/>

<div class="hikashop_registration_surname_line form-group" id="hikashop_registration_surname_line">
    <div class="key col-sm-3 control-label">
			<label for="surname">
				<?php echo JText::_( 'HIKA_USER_SURNAME' ); ?> *
			</label>
		</div>
			<div class="col-sm-9">
				<input type="text" name="data[user][surname]" id="surname" value="<?php echo $this->escape($this->mainUser->get( 'surname' ));?>" class="inputbox required" maxlength="50" />
				
			</div>

Hi,

I still can't understand.
When i register with joomla registration page it will add surname field to hikashop created custom field. So thats OK.
The only problem is that if registered in checkout with hikashop registration it wont add/save surname field to hikashop user or joomla user. Isnt it hikashop related? Should't plugin be created for hikashop so it would save hikashop user information too?
Then how column called "Name" is synchronized? Maybe i could do same without custom field. As it wont have such field in custom field?

Ok, thanks. I just thought maybe I am doing something wrong cause there was no synchronization btw hikashop custom field and hikashop it self.

Will look into plugin.

Thanks
