I have a form in php that allows users to edit their user profile after the user logs in. It is prefilled with the users current info and when it is submitted, it updates the database. However, when it returns to the edit user profile page, the prefilled text is not updated. It only seems to update when the user re-logins. I followed this old article Update SESSION Variabled when form is submitted. I've added 'session_start();' but it still doees not reflect the changes.
**
Login-exec.php**

<?php
    //Start session
    session_start();

    //Include database connection details
    require_once('config.php');

    //Array to store validation errors
    $errmsg_arr = array();

    //Validation error flag
    $errflag = false;

    //Connect to mysql server
    $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
    if(!$link) {
        die('Failed to connect to server: ' . mysql_error());
    }

    //Select database
    $db = mysql_select_db(DB_DATABASE);
    if(!$db) {
        die("Unable to select database");
    }

    //Function to sanitize values received from the form. Prevents SQL injection
    function clean($str) {
        $str = @trim($str);
        if(get_magic_quotes_gpc()) {
            $str = stripslashes($str);
        }
        return mysql_real_escape_string($str);
    }

    //Sanitize the POST values
    $login = clean($_POST['login']);
    $password = clean($_POST['password']);



    //Create query
    $qry="SELECT * FROM members WHERE login='$login' AND passwd='".md5($_POST['password'])."'";
    $result=mysql_query($qry);

    //Check whether the query was successful or not
    if($result) {
        if(mysql_num_rows($result) == 1) {
            //Login Successful
            session_regenerate_id();
            $member = mysql_fetch_assoc($result);
            $_SESSION['SESS_MEMBER_ID'] = $member['member_id'];
            $_SESSION['SESS_FIRST_NAME'] = $member['firstname'];
            $_SESSION['SESS_LAST_NAME'] = $member['lastname'];
            $_SESSION['SESS_AGE'] = $member['age'];
            $_SESSION['SESS_GENDER'] = $member['gender'];
            $_SESSION['SESS_DISEASES'] = $member['diseases'];
            session_write_close();
            header("location: member-profile.php");
            exit();
        }else {
            //Login failed
            header("location: login-failed.php");
            exit();
        }
    }else {
        die("Query failed");
    }
?>

surely the session changes should happen immediately after you successfully update the db in save_edit.php?

0

Only the database is updated. The fields that are supposed to be updated are not.

0

all pages: login form -> loginscript.php: get user details (into session) - if success (return to previous page if not) -> profile.php: profile page (populated) - if edit and send -> save_edit.php: new data into DB and session - redirect -> profile page

That's how I see it should work.
