    Combing User table with Form table

    I have setup a login system on my site, in which the logged in user (user table) would be able to fill out an insurance form that's saved in the database in a separate table - form_one table.

    user table

    username - varchar(30), Null: No, Default: None - Primary Key
    password - varchar(32), Null: Yes, Default: NULL
    userid - varchar(32), Null: Yes, Default: NULL
    userlevel - tinyint(1), UNSIGNED, Null: No, Default: None
    email - varchar(50), Null: Yes, Default: NULL
    timestamp - int(11), UNSIGNED, Default: No, Default: None
    valid - tinyint(1), UNSIGNED, Null: No, Default: 0
    name - varchar(50), Null: Yes, Default: Null

    form_one table

    formid - varchar(32), Null: No, Default: None - Primary Key
    username - varchar(30), Null: No, Default: None - Foreign Key
    email - varchar(50), Null: Yes, Default: NULL
    phone - varchar(12), Null: No, Default: None
    address - varchar(50), Null: No, Default: None
    timestamp - int(11), UNSIGNED, Null: No, Default: None
    name - varchar(50), Null: Yes, Default: NULL
    quotationinsurance - enum('insurance', 'quotation'), Null: No, Default: None
    etc...

    Below is my php function for UPDATE & SELECT

    function updateUserForm($username, $field, $value){
    /*$q = "UPDATE ".TBL_FORM_ONE." SET ".$field." = '$value' WHERE username = '$username'";*/ - Original code
    $q = "UPDATE ".TBL_USERS.", ".TBL_FORM_ONE." SET ".$field." = '$value' WHERE username = '$username'";
    return mysql_query($q, $this->connection);
    }

    function getUserForm($username){
    /*$q = "SELECT * FROM ".TBL_FORM_ONE." WHERE username = '$username'";*/ - Original code
    $q = "SELECT * FROM 'TBL_USERS', 'TBL_FORM_ONE' WHERE 'username' = '$username' AND TBL_USERS.username = 'TBL_FORM_ONE.username'";
    $result = mysql_query($q, $this->connection);
    /* Error occurred, return given name by default */
    if(!$result || (mysql_numrows($result) < 1)){
    return NULL;
    }

    How can I join these two tables where the username in both tables are tied together. In other words, once a user is logged in, they can fill out the form and the data from that form would be tied to each unique user.

    Any help would be appreciated! :-)

    You could do it like this:

    Code:
    SELECT u.*, f.*
    FROM TBL_USERS u
    JOIN TBL_FORM_ONE f ON f.username = u.username
    WHERE u.username = '$username'
    If columns in both tables have the same name, the later will take precedence, unless you give them different aliases of course.

    Would the UPDATE function be done in a similar way?

    Although I don't personally do it this way, I believe it works the same:

    Code:
    UPDATE TBL_USERS u
    JOIN TBL_FORM_ONE f ON f.username = u.username
    SET u.email = 'test@test', f.email = 'test@test'
    WHERE u.username = '$username'
