How to assign session variables from login page?

[Apollo6]

This maybe part HTML question but also PHP...

I have a login page where I have user_id and password input fields. Once both are entered, user clicks submit. How do I go about setting session variables from this page to pass to the next page(s)?

My inputs are as follows:
Input Name="user_id" id="user_id"
Input Name="passwd" id="passwd"

When the form is submitted, the script to which the form submits can accept the form data and copy the values to the session variables.

Just issue session_start() in the receiving script and assign values to elements in the $_SESSION superglobal array. The values will come from the $_POST or $_GET arrays.

Subsequent pages will then also issue session_start(), and reference the values in the $_SESSION array.
