Attach User Id to inserted records

Feb 22, 2012 3:57 PM

Tags: #php #dreamweaver #database #mysql

I'm building a page/form that will allow users to add new rows to my database.  I want to auto-populate the 'student_id' column in the table they are inserting into with the information contained in my table 'users' that contains their login information.  In both tables, their numeric id is 'student_id'. I have their username = their email.


How is this done?


to recap, i have them inserting rows into a table called sponsors.  I want the column sponsors.student_id to autopopulate with their student_id from the users table based on the fact that they are logged in as said user.


I know this must be possible, but I'm incredibly new to all of this.


Thanks in advance for any help!

    Typically when someone logs in you store their ID in a session variable. Are you storing the student_id or username in the session variable. If the former, then obviously you just need to use that in the insert statement.  If the latter, then you have 2 options.


    1. When retrieving their info at login, also capture the student_id. Then you can use the session variable directly in your insert statement
    2. Use a subselect in the insert statement that retrieves the student_id based on the username.
