Need some help with a blog mod I've created

corruptcity || skalman · September 21, 2023

Hi I'm looking for help, adivce or suggestion on how I could fix my problem I've got. So I have made this blog mod for my website to the I can post about the roadmap, game info etc that can be viewed either logged in or out but was after ideas on how I could make this working using only one page as I currently have blogs and blogsnl (blogs Non Logged) on serperate scripts. when I first did create this I did have it on one page but I couldn't find a way for the script to determine if you were logged in or not and pick the right globals file either the globals or globals_nonauth without causing other problems or errors due to the wrong globals called, so I split up the file into two just going for the easy fix right now
I will include what I have don sofar but bare in mind this isn't the finished mod and will be recoded if I can fix the problem cheers. ps if anyone wants to use my codes as a starting point for their own blog feel free to.

if (isset($_SESSION['userid'])) {
    include("globals.php"); // Include the globals.php file for logged-in users
} else {
    include("globals_nonauth.php"); // Include the globals_nonauth.php file for non-logged-in users
}

have you tried something like this?

You may get a session already started issue tho

Edited September 21, 2023 by AdamHull
I was correct with my session call

corruptcity || skalman · September 21, 2023

yeah that was the first thing I tried would work fine when logged in but got the session error when not logged in but couldn't get around that even with chatgpt help

AdamHull · September 21, 2023

is it the header already sent or what ever?

if it is you could use something like

if (session_status() === PHP_SESSION_NONE) {
    session_start();
}

in your globals_nonauth

Managed to fix this but had to do some jankiness to get it working and used something I've never used before or even was a thing. I had to use output buffering for globals.php then in globals_nonauth put an if statement in so that it doesn't duplicate what was in globals, also had to add a shit ton of isset() into the header page before I managed to get it to work. I will now Include the working code in case it helps one else in the future
Blog.php

<?php

#set_error_handler('error_php');

if (strpos($_SERVER['PHP_SELF'], "globals_nonauth.php") !== false)
{
    exit;
}
if ($_SERVER['PHP_SELF'] !== '/blog.php') {
    session_name('MCCSID2');
    @session_start();
    if (!isset($_SESSION['started']))
    {
        session_regenerate_id();
        $_SESSION['started'] = true;
    }
    ob_start();

    require "lib/basic_error_handler.php";
    set_error_handler('error_php');
    include "config.php";
    define("MONO_ON", 1);
    require "class/class_db_{$_CONFIG['driver']}.php";
    require_once('global_func.php');
    $db = new database;

    $db->configure($_CONFIG['hostname'], $_CONFIG['username'],
            $_CONFIG['password'], $_CONFIG['database'], $_CONFIG['persistent']);
    $db->connect();
    $c = $db->connection_id;
    $set = array();
    $settq = $db->query("SELECT *
                        FROM `settings`");
    while ($r = $db->fetch_row($settq))
    {
        $set[$r['conf_name']] = $r['conf_value'];
    }
}


?>

globals_nonauth.php
<?php
    // Include your global settings for logged-in users

    ob_start();
    require_once("globals.php");
    $output = ob_get_contents();
    ob_end_clean();
       
    if(isset($_SESSION['userid']) && $_SESSION['userid'] > 0) {
        echo"Hello {$ir['username']}<br />"; 
        echo "Welcome user";
        $loggedIn = true;
        // Add code here to display blog posts for logged-in users
    }
    else {
        // Include only the specific data you need for non-logged-in users
        require_once("globals_nonauth.php");
        $loggedIn = false;
        // Display a welcome message for guests
        echo "Welcome Guest <br />";
        
        // Here, you can use $nonLoggedInData to display blog posts for non-logged-in users
        // Replace the following line with your actual code to display blog posts.
        echo "Display Blog Posts Here";
    }
?>

Also would like to say thanks to adam for his assistance
