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 have a database with three tables "Cantiere "Affidataria "SubAffidataria"
"Cantiere" has a 1 to N relationship with Affidataria "Affidataria" has a 1 to N relationship with subAffidataria
so in Affidataria there is a fk of "Cantiere" called "fkIdCantiere" and in subAffidataria there is a fk of "Affidataria" called "fkIDAffidataria"
my problem is to go from a "function" to the id of fkIdAffidataria
in fact, if you notice in the screenshot you see the carers but not the sub-delegates. so I have to make sure to save the fkIdAffidataria to put it in the QUERY ..
enter image description here
"0 results" indicates that the query did not find any subAffidataria .. when in fact they are in the database

I've read about the nl2br() command but they echo out the variable to make it work but my variable is inside a list that I echo out.
Should I somehow put the nl2br() command in my if statement where I'm setting up the output or should I be looking somewhere else for my answer.
I have made 2 extra detail variables to output so I get 3 lines of text for the description of my product but there has to be a better way of doing it than that. I would think 1 detail variable with all the info would be the preferred way of doing it
I have tried to search for it but I'm afraid I'm just not asking the right question so any help in the right direction is appreciated.
<?php require_once './connections/connect_mysqli.php';
$conn = dbConnect('read');
$sql = "SELECT * FROM products ORDER BY id ASC LIMIT 6 ";
$result = $conn->query($sql) or die($conn->error);
$i = 0;
$flatlist = "";
while($row = $result->fetch_array(MYSQLI_ASSOC)){
$id = $row["id"];
$product_name = $row["product_name"];
$details = $row["details"];
$details2 = $row["details2"];
$details3 = $row["details3"];
$price = $row["price"];

Want to point out you close the details <p> before the 2nd and 3rd lines. You probably want to close that after third line.
<p style=font-size:14px;>' . $details . '<!-- remove here: </p> --><br />
' . $details2 . '<br />
' . $details3 . '<br /><!-- add here: --></p>
If you keep your same database structure, you can define into one variable after retrieving like:
$details = $row["details"] . '<br/>' . $row['details2'] . '<br/>' . $row['details3'];
And then just refer back to $details later on.
Why don't you want to use nl2br()? This would allow you to store multiple lines all into details column. Then you would just use:
$details = nl2br( $row["details"] );`
Here are my edits to your code:
<?php require_once './connections/connect_mysqli.php';
$conn = dbConnect('read');
$sql = "SELECT * FROM products ORDER BY id ASC LIMIT 6 ";
$result = $conn->query($sql) or die($conn->error);

$id = $row["id"];
$product_name = $row["product_name"];
$details = $row["details"] . '<br/>' . $row['details2'] . '<br/>' . $row['details3'];
$price = $row["price"];
if ($i % 4 == 0) {
$flatlist .='<tr><td width="250px" align="center"><img src="images/' . $id . '.jpg"><br/>

Change your implode line to be:
$emp = implode( "','", $employee );
and your query to be:
"SELECT * FROM securitystaffdetails WHERE employeename IN ('" . $emp . "')";
you missed ().
$sql = "SELECT * FROM securitystaffdetails WHERE employeename IN ('" . $emp . "')";
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

The RoR code would be something like this:
Project.where("status > ?", 10)
http://guides.rubyonrails.org/active_record_querying.html
The link will give you a large list of mysql queries and their RoR counterpart.
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.
