What do you need help with?
Hi everyone. I need some help with the page parameters option.
I have created 3 pages for registering new app users - 1 for my customers (for user validation) , 1 for parents of children using our transport service and 1 for the children. The pages consist of a form only. Each form can navigate to the next form and create a new record but the parents and children are not linked.
I presume I have to use a page parameter to link the two records. I therefore added a text field to the Register Child form with data source Single User:id which gives me the correct id for the parent from the Users table. But how do I link the Child to the Parent? I cannot write that value to the Children table.
I have tried with a form on a Page, with forms views (too limited also) and with a url parameter (don’t know how to get user id from form).
Help me p-l-e-a-s-e!!
Hey @Herman_26, you need to add :id to the page settings:
And then, in the Row ID section, choose this parameter:
Let me know if you need more details 
Thank you very much, @olgatrykush ! I have played around with parameters for a few days and that made quite a few things now possible. I have two questions and one unrelated problem.
The user completes a registration form with email address and password, then opens the Parent Details form and after that the Child Details form. This works perfectly with the user’s email address passed to the parent’s form (probably not necessary?) and the parent’s last name passed to the child’s form.
I want to pass the user’s identifier to the Parent’s record (Submit button writes it to the table) and then the Parent’s ID to the Child table to link them. I noticed, when using the RowID as parameter, it stays the same. I thought at first that it was not carried forward but then saw it was the same in the users table. So it seems to not create a sequential Row D.
Secondly, can I use an autonumber field for the link instead of Row ID?
After completing the registration process, the user goes to the login form, after which he lands at the root form. Is this process correct, because the login form does not accept the password (which was created in the user registration form.)
Please see attached screenshots.
Many thanks.
Hey @Herman_26, nice! Glad to hear you’re making progress with your app. I also wanted to share that we published this short guide explaining how to work with path parameters: How to Use Path Parameters to Link Pages in Baserow Apps
@frederikdc could you please help me with this question?
No, you can only use Row ID to uniquely identify a record
