Back with more noob questions

so I was following a page in setting up a login system and so far it works how I want except for one minor thing

So I want when a user is logged into the system to see Profile div instead of Login and Register and I do that in my index.php with the following

 <?php  if(isset($_SESSION['username'])){
	echo 
    	"<div class='profile'> 
  		    <a href='logout.php'>Logout</a>
  		    
  		    </div> 
  		    ";
    }
    else{
    	echo 
    	"<div class='loginregister'> 
  		    <a href='login.php'>Login</a>
  		    <a href='register.php'>Register</a>
  		    </div> 
  		    ";
    }
    ?>

So when a user logs in it hits the login.php which looks like this 

<?php
    require('dbconnect.php');

    session_start();
    // When form submitted, check and create user session.
    if (isset($_POST['username'])) {
        $username = stripslashes($_REQUEST['username']);    // removes backslashes
        $username = mysqli_real_escape_string($conn, $username);
        $password = stripslashes($_REQUEST['password']);
        $password = mysqli_real_escape_string($conn, $password);
        // Check user is exist in the database
        $query    = "SELECT * FROM `Users` WHERE User='$username'
                     AND password='" . md5($password) . "'";
        $result = mysqli_query($conn, $query) or die(mysql_error());
        $rows = mysqli_num_rows($result);
        if ($rows == 1) {
            $_SESSION['username'] = $username;
            // Redirect to user dashboard page
            header("Location: index.php");
        } else {
            echo "<div class='form'>
                  <h3>Incorrect Username/password.</h3><br/>
                  <p class='link'>Click here to <a href='login.php'>Login</a> again.</p>
                  </div>";
        }
    } else {

and it starts the session_start() function whilst also allocating $_SESSION['username'] = $username so in theory when index.php loads if SHOULD (?) hit the correct if statement in the index.php file now outputting the Profile div instead of the Login and Register div.

Except it doesn't.

However when I include the auth_session.php at the top of my index.php file like (currently uncommented to test)

//<?php //include auth_session.php file on all user panel pages 
//include("auth_session.php");
//?>

with the Auth_session file looking like

<?php
    session_start();
    if(!isset($_SESSION["username"])) {
        header("Location: login.php");
        exit();
    }
    else { 
    }
?>

It does show the correct Profile div instead of the Login  and Register div.

So I'm trying to understand what is happening here as from the look of it the $_SESSION['username'] is allocated within login.php and the session_start() function is also started in login.php

So why would I need auth_session.php to be ran in order for the correct divs to show (I've not included auth_session.php as I want people to be able to see the site that aren't logged in)

Warm regards

Greetings to all!

Newbie here, I just signed up this morning. I have an issue with a code I have been using for several years with multiple files/directories. Until recently all of the files have worked flawlessly. Now I have one file in a directory that does not display the text I which I am attempting to call up and it was working until recently.

As stated above I have the same code in multiple directories and files and it works flawlessly in all files except for the one. I have spent a few hours attempting to remedy the situation with no success. I have looked at the source code for the errant file and that shows the text to be displayed but it is not displayed in any browser on several computers, whether Windows or Mac OSX. I even went so far as to delete the directory the file was in and re-uploaded the entire directory from a backup that is 2 or 3 years old, no change. I copied the entire coding from a working file with the same coding, deleted all the coding in the errant file and pasted the working coding into the errant file. - no change

I have attached screen shots of the coding in errant file and one of many other files that work flawlessly with the php code that is involved highligted. Also attached are the browser page source files for the same errant and working files. The screen shots in order are errant file code, working file code, errant file source, and working file source.

Every file with the same code as the errant one work flawlessly except for the errant one, and I have 11 files to be displayed on my website at https://TheLoveOfGod.org They are all listed under the Devotionals menu button except for one which is displayed on the home page. I have absolutely no training in web design, I am self taught. I began by hand typing html coding over 30 years ago and am now using Word Press with Elementor . I do not understand why this is happening. Can any of you offer assistance to resolve this. I thank you in advance for your assistance.

Respectfully,
dan

Hi, this query runs fine when I run it from PHPMyAdmin:
 

UPDATE `tran_term_taxonomy` SET `description` = (SELECT keyword from `good_keywords` ORDER BY RAND() LIMIT 1,1) WHERE `tran_term_taxonomy`.`taxonomy` = 'post_tag' AND `tran_term_taxonomy`.`description` = "" LIMIT 1

However, when I run the same query in a PHP file on my server, the page doesn't load at all. The message I get is: www.somesite.com is currently unable to handle this request. HTTP ERROR 500. This is my PHP code:

<?php 
include("/database/connection/path/db_connect.php"); 

$result4 = mysqli_query($GLOBALS["___mysqli_ston"], "UPDATE `tran_term_taxonomy` SET `description` = (SELECT keyword from `good_keywords` ORDER BY RAND() LIMIT 1,1) WHERE `tran_term_taxonomy`.`taxonomy` = 'post_tag' AND `tran_term_taxonomy`.`description` = "" LIMIT 1");
echo $result4;

?>

So how do I make this query work please? Thanks for your guidance.
