Shoutbox


 Share

Recommended Posts

Ok, I wrote a shoutbox script, which is viewable by visiting: http://www.imperialized.net/shoutbox/shoutbox.php

 

What my question is, do you see any problems with the functions or the code. Also, how can I better write my next page script? I'm sure there is a better way.

 

 

<?php
session_start();
/**
* @author David Lallone
* @title Shoutbox
* @copyright Imperialized.net 2008
* NOT FOR DISTROBUTIONAL PURPOSES (DO NOT USE WITHOUT PRIOR CONSENT)
*/

//Set Time & Date for easy display and also for use when posting a shout!
date_default_timezone_set('EST');

//Connect to DB
include("../sql/db_con.php");


//Check to see if the session is registered
$admin = $_SESSION['admin'];

//If the logout button was pressed, set session to 0
if($_POST['logout']) {
$pass = $_POST['password'];
$realpass = "bigmak50";
if($pass == $realpass) {
	$_SESSION['admin'] = 0;
	$admin = $_SESSION['admin'];
    } else {
	print "Wrong Password";
}
}

//Login button was pressed, check password then register session
if($_POST['admin_login']){
$pass = $_POST['password'];
$realpass = "Password Removed For Security Purposes.";
if($pass == $realpass) {
	$_SESSION['admin'] = 1;
	$admin = $_SESSION['admin'];
} else {
	Print "Wrong password, asshole.";
}
}



//What page are we at? If none, Set $pg = 1
//Also set the $start and $end variables for the pages.
$pg = $_GET['page'];
  if(is_numeric($pg)){
  if ($pg == "") {
  	$pg = 1; 
$start=0; 
$end=10;
 }
  if ($pg == 1){
  		$start=0; 
    $end=10;
} else {
  	$start = $pg * 10 - 9;
  	$end = $pg * 10;
}
} else {
  $pg = 1;
  $start=0; 
  $end=10;
}

//Count our shots for page usage and display
$count_shouts = "Select * from shoutbox";
$count_shouts_query = mysql_query($count_shouts);
$tshouts = mysql_num_rows($count_shouts_query);

//Set Date & Time
$date = date("m-d-Y");
$time = date("g:i a");

//What is the page supposed to do? 
$action = $_GET['action'];

?>

        </script>";
}
}
// SEE IF WE HAVE SET THE COOKIE YET!
$name = "";

CHMOD, done.

 

 

Anyways, you all were talking about this AJAX... I've googled it but am having some trouble understanding it. Could anyone point me in the right direction?

 

/edit: nevermind, I did not realize there was an AJAX forum here. 

 

// Does my Next Page & Previous Page code look ok? It looks so boggled and suggestions?
