**My Mautic version is:** 2.16.0  
**My PHP version is:** 7.0.33-1

Hello there !  
I’m new to mautic and want to know more about forms.  
I searched a lot on the forum and google but can’t find what i’m looking for so here i am.

**My needs :**  
I want to create a mautic form ans use it to update my contacts informations from a remote website or from the unsubscribe page.

**What i have done so far :**

- i create a standalone form, i added a radio group to update the field “customers\_newlsetter” (boolean type).
- i linked this form to a landing page.
- in my email i linked the landing page in the “Preference center page”.
- i created a campaign with this mail.

**Problematic :**  
All went well, i received the email from my campaign, when i clicked on the “unsubscribe link” i was redirect to my landing page with my form displayed.

But when i post my form, the succes message pop, no error. but nothing updated, the custom field “customers\_newlsetter” wasn’t update for my contact.

And it was kind of normal since no contact ID was post with my form.

**My question :**  
How to associate a contact with a mautic form ?

- i need it in a case of unsubscribe but also if i linked a form on another website with script balises.

(the doc i read about it : [https://mautic.com/help/forms/](https://mautic.com/help/forms/))

If someone had a suggestions it would be helpfull.

Thanks in advance for your help and sorry if the question was already asked, i didn’t find any related post to answered my needs.
