This code is from O'Reilly Head First PHP&MySQL book. The script doesn't recognize the username and password somehow:
<?php
$username = 'rock';
$password = 'roll';
if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) ||
($_SERVER['PHP_AUTH_USER'] != $username) || ($_SERVER['PHP_AUTH_PW'] != $password)) {
// The user name/password are incorrect so send the authentication headers
header('HTTP/1.1 401 Unauthorized');
header('WWW-Authenticate: Basic realm="Guitar Wars"');
exit('<h2>Guitar Wars</h2>Sorry, you must enter a valid user name and password to access this page.');
}
?>
And this is the script, from which the authentication file is required:
<?php
require_once('authorize.php');
?>

Can you see what's wrong here?
Thank you!
The authentication code is perfectly fine.
You might have extra spaces (before <?php) or something else there before the header() calls.. in that case you don't see the authentication popup.

So I have a website that runs a cycle on a database as long as there is a record in it.
It also puts two buttons in each row within the table.
Each button has the same name.
If I press one of the buttons, how can I get the ID of that button (which points to a Youtube link from the database) to be included in a SQL query.
Here is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<link rel="stylesheet" href="style.css">
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">

<body>
<form method='POST'>
<?php
session_start();
if (isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true) {
echo "Welcome to the member's area, " . $_SESSION['modname'] . "!";
} else {
echo "Please log in first to see this page.";
}
$link = mysqli_connect("localhost", "asd", "asd", "mediareq");
if($link === false){
die("ERROR: Could not connect. " . mysqli_connect_error());
}
$sql = "SELECT * FROM requests";
if($result = mysqli_query($link, $sql)){
if(mysqli_num_rows($result) > 0){
echo "<table>";
echo "<tr>";
echo "<th>link</th>";
echo "<th>Twitch Név</th>";
echo "<th>Üzenet</th>";
echo "<th>Engedélyezés</th>";
echo "<th>Elutasítás</th>";
echo "</tr>";
while($row = mysqli_fetch_array($result)){
echo "<tr>";
$link = $row['link'];
echo "<td>" . "<iframe width='560' height='315' src='$link' frameborder='0' allowfullscreen></iframe>" . "</td>";
echo "<td>" . $row['ttvname'] . "</td>";
echo "<td>" . $row['msg'] . "</td>";
echo "<td>" . "<input type='submit' id='$link' value='' name='enable'></input>" . "</td>";
echo "<td>" . "<input type='submit' id='$link' value='' name='eject'></input>" . "</td>";
echo "</tr>";
}
mysqli_free_result($result);
if (isset($_POST['enable'])) {
$ID = $_POST[$link];
echo $ID;
}
} else{
echo "Még nem kaptál videót, várjál már egy kicsit vagy csak tolj egy F5öt Pog Pog Pog";
}
} else{
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
mysqli_close($link);
?>
</form>
</body>
</html>
The website looks like this: https://imgur.com/a/MWVj7L5
If it can't be done that way, what can I do in this case to keep the loop but since it has to be dynamic, and somehow get it to pick the link from each button that it stores in the ID (or some other way)
NEWBIE ALERT
Ive been reading for hours but cannot see how to do what I want. I have an SQL DB with a list of medication and dosages etc. Im trying to create an 'edit' page so i can select the medication from a dropdown list(this appears to work), and edit certain parts of it(size, box quantity, doseage etc.
the problem is i cant get the selected medication item(from dropdown) to become a variable or if neccessary, forward to a 2nd PHP page.
Ive left a couple of attempted edits in there but they caused errors (TRIED NOT WORK)
As it is, It is loading editmed.php to load my edit page on submit. (not sure if this is the best way of doing it).
Any help would be great thanks

i dont know how to assign the variables from the input form, thats where my issue is.If i get a variable assigned then i can create the actual editing part.
I'm working on a server based POS and I have a php page that displays the client current money on a table, I have 2 tables (Mov_ctes and Clientes), it works fine when I add WITH ROLLUP on the mysql query, It displays the Total but without A Name (NULL value), so I used
IFNULL(Clientes.Nombre,'TOTAL')
so It could change the NULL value to TOTAL, I entered the whole command on mysql and worked fine, however if I enter the same query via PHP it doesnt output the "Nombre" column
heres my code and a Mysql screenshot

You need an alias for the column, otherwise the column name will be IFNULL(Clientes.Nombre,'TOTAL'):
SELECT IFNULL(Clientes.Nombre,'TOTAL') AS Nombre

I have a system where users can send and receive messages and I need to make a way for them to directly reply to the messages.
This is a test code to make the page echo what should be retrieved and set as a session, but it is not echoing anything.

I need the session $_SESSION['reply'] to be set as the variable $username2 and it does not seem to be working.
Move session_start(); on top of the PHP code. You are accessing $_SESSION['reply'] = $username2; before that which wont work.
What I was doing was incorrect. I had to move
$_SESSION['reply'] = $row['from'];
$username2 = $_SESSION['reply'];`
from after the query to
while ($row = mysqli_fetch_array($data)) {
$_SESSION['reply'] = $row['from'];
$username2 = $_SESSION['reply'];`
and then it echo'd correctly. Thanks for the help from everyone :)
I cant figure out how to display MySql information using Ruby on Rails.
This is the query i want to run
SELECT name, description FROM projects where status > 1
If someone can translate to Rails the code below it would be greatly apreciatted

foreach ($conn->query($sql) as $row) {
print $row['name'] . "\t";

The RoR code would be something like this:
Project.where("status > ?", 10)

The link will give you a large list of mysql queries and their RoR counterpart.
