Private Message Outbox for Search and Match Users

This script is called message-outbox.php

First, we use the check-id.php script to ensure that the session id variable is set, and send the user to Login to MC Search and Match Profile and Account Management if it is not. Then we put the session variable 'username' into $U—we will be checking that it is set in a second. Then we define a named constant '_NODIRECTACCESS'. We include the config.php file (in the includes folder) which uses the PHP defined() function to check on this constant. If it is not set, we are thrown out of the config.php file like yesterday's trash.

Next we check if the session variables 'groupname', 'username', and 'userid' are set. If not, we are sent to the login-to-mc.php script. We make sure $U is still equal to the session variable 'username', that it is not an empty string, and that it's at least 6 characters long or . . . you guessed it . . . the login script. We make sure the session id is set and send them away if not.

Next we have the getgroup() function. The user's id is put into $fromuser early on, then when the display table needs it, it is put into $us and this function is run, which uses the id to get the user's groupname, which in turn is displayed in the display table after "Messages from:".

A result set is put into $sql of a query of the MySQL privatemessages table in which all messages from this user are grabbed and the results are in descending order of the datesent field. These results have the needed data, in the needed order for displaying the user's outbox messages.

After a bit of browser sniffing and display tweaking using DHTML, we hop by the unused JavaScript textCounter() function and get to the outbox displaying. Check out the display table caption:

<caption><b>Messages from: <?php $us=$fromuser;getgroup($us);
echo $gr; ?></b></caption>

HTML doesn't seem to mind if PHP function calls and echo statements are done right in the middle of its displaying. Then, returning to a PHP block, the mysql_fetch_array() function grabs the sorted results set we earlier stuck into $sql and gets one row/record at a time and displays the contents onscreen. The htmlentities() and stripslashes() functions make the data safe to display. We use the PHP date() function, which formats a local time/date. The function returns a string formatted according to the format string in the parameters. Our chosen format string is 'Y/m/d'.

The script below is called: message-outbox.php


<?php

//message-outbox.php

include_once"check-id.php";
$U=$_SESSION['username'];
define('_NODIRECTACCESS', TRUE);
include_once"includes/config.php";
if (!isset($_SESSION['groupname']) || !isset($_SESSION['userid']) || !isset($_SESSION['username']) || $_SESSION['username']<>$U || !isset($U) || $U=="" || strlen($U)<6 || !isset($_SESSION['sessionid'])){echo '<script language="javascript">alert("Please login."); window.location = "login-to-mc.php";</script>';}

function getgroup($us){
global $us,$gr;
$Q = mysql_query("SELECT groupname FROM mc_members WHERE id = '$us' LIMIT 1") or die(mysql_error());
$row=mysql_fetch_assoc($Q);
$gr=$row['groupname'];}

$fromuser = $_SESSION['userid'];

$sql = mysql_query("SELECT * FROM privatemessages WHERE fromuser = '$fromuser' AND outdel = '0' ORDER BY
datesent DESC");

?>
