Good morning all,

I am new to cakephp. Here is my concern, I am practicing to design an online subscription site. The customer arrived on the site clicks on an offer to subscribe and must be redirected to a customer information registration form then after validation, is directed to another page which displays the details of his subscription and finally he confirms his subscription . The problem is that I don’t know how to go about keeping information in memory at each stage of form validation.

Could help me to have a tip or method to overcome this problem. I thank you in advance.

I’m using the cakephp 3.8 version

One common way is to use [sessions](https://book.cakephp.org/4/en/development/sessions.html). This one of the strategies use by the [Authentication plugin](https://book.cakephp.org/authentication/2/en/index.html) too.

I have a customer table, an offer table and a subscription table and I would like to use the customer table for authentication but this does not go out. I have reserved the user table for the administration part. Do you have a solution for me? I’m grateful to you.

Are you trying to save the customer record to a session so you can retrieve it on subsequent requests?

Can you share some code showing where your process is failing?

I present you the codes that I put for the authentication of the customers before they subscribe to an offer

</div>

How is it failing?

- Is there an error message?
- Are the expected records being created in the database?
- Is the password hashed in the database as expected?
- Is there any Auth data showing in the session?

You’re trying to log in with a user record stored in the clients table? What steps have you taken to set that as the table that will be used for authenticating those logins?

I changed the code in the AppController file

Nothing about this changes what _table_ it will be looking in. It changes what _controller_ will be used, but that controller just calls `$this->Auth->identify()`, and by default that’s going to be using the `users` table.

In this case do you have a solution for me?

Documentation is [here](https://book.cakephp.org/3/en/controllers/components/authentication.html#configuring-authentication-handlers), see the `userModel` key.
