PHP - Help -- Creating Simple Chatbox

Hello, im very green to php and I am having trouble creating a simple log in script. Not sure why this is not working, maybe a mysql_query mistake? I am not receiving any errors but nothing gets updated in the members table and my error message to the user displays.  any help is appreciated! here is my php:


<?php
session_start();

$errorMsg = '';
$email = '';
$pass = '';

if (isset($_POST['email'])) {
   $email = ($_POST['email']);
   $pass = ($_POST['password']);
   
   $email = stripslashes($email);
    $pass = stripslashes($pass);
   $email = strip_tags($email);
   $pass = strip_tags($pass);
   
if ((!$email) || (!$pass)) {
   $errorMsg = '<font color="#FF0000">Please fill in both fields</font>';
}else {
   include 'scripts/connect_db.php';
   $email = mysql_real_escape_string ($email);
   $pass = md5($pass);
   
   $sql = mysql_query("SELECT * FROM members WHERE email='$email' AND password='$pass'");
   
   $log_check = mysql_num_rows($sql);
   
if ($log_check > 0) {
    while($row = mysql_fetch_array($sql)) {
      
      $id = $row["id"];
      $_SESSION['id'];
      $email = $row["email"];
      $_SESSION['email'];
      $username = $row["username"];
      $_session['username'];
      
      mysql_query("UPDATE members SET last_logged=now() WHERE id='$id' LIMIT 1");
      
   }//Close while loop
   echo "You are logged in";
             exit();
}
else {
   $errorMsg = '<font color="#FF0000">Incorrect login data, please try again</font>';
}


     }
}
?>



and the form:

<?php echo $errorMsg; ?>
<form action="log_in.php" method="post">
Email:<br />
<input name="email" type="text" /><br /><br />
Password:<br />
<input name="password" type="password" /><br /><br />

Hello everyone,

I found a tutorial on creating a pdf with php and I just tried to create a basic pdf to see if it worked and modify it from there.  Here is the link to the tutorial: http://www.astahost.com/info/tfclt-create-pdf-php-create-fly-pdf-web-server.html

Well, after uploading the following php file to the server and testing it, I got this error:

Fatal error: Call to undefined function pdf_new() in /home/caresa6/public_html/BubblyBounce.com/admin/pdftest.php on line 2

Here's the code that produced the error:
Code: [Select]
<?php
$mypdf = PDF_new();
PDF_open_file($mypdf, "");
PDF_begin_page($mypdf, 595, 842);
$myfont = PDF_findfont($mypdf, "Times-Roman", "host", 0);
PDF_setfont($mypdf, $myfont, 10);
PDF_show_xy($mypdf, "Sample PDF, constructed by PHP in real-time.", 50, 750);
PDF_show_xy($mypdf, "Made with the PDF libraries for PHP.", 50, 730);
PDF_end_page($mypdf);
PDF_close($mypdf);

$mybuf = PDF_get_buffer($mypdf);
$mylen = strlen($mybuf);
header("Content-type: application/pdf");
header("Content-Length: $mylen");
header("Content-Disposition: inline; filename=gen01.pdf");
print $mybuf;

PDF_delete($mypdf);
?>

Can anyone help me figure out what to do from here?  I have some PHP knowledge, but I'm treading in uncharted waters with this, so I am totally lost.  Thanks in advance.

Hi,

I have decided to try and write some OO php.

I have a simple class with one function. I am trying to instantiate an object of that class using the new operator but get an error.
Parse error: syntax error, unexpected T_OBJECT_OPERATOR in C:\wamp\www\School\addcourse.php on line 38
Code: [Select]

<?php 
    $CDBController = new CMasterDataController; //THIS IS LINE 38
    CMasterDataController->PerformQuery("SOME SQL HERE");
?>

I am including the file that contains this class (CMasterDataController) in this file (addcourse.php). The version of PHP i am using is 5.3.8.
Does anybody know what I am missing?

Thanks,
Joe

Write a  class for feeding a horse. The Horse object should keep track of the last time it was fed and calculate when it is hungry. Assume there is another class that checks the horse every 10 minutes to see if it is hungry and if it is, it calls another method which feeds it. There should be about 3 methods on the class, but more can be added if needed. 

I want to create a REST  API for my website. What I want to do is to display advertisements from my database on websites that I sell to clients. Their website will call my database for advertisements to display on their websites. Also, I am performing a site validity check where the client's site would send the site URL, site name, and site token to my database for validation. If it returns false then the site will not display as it will be invalid according to my database. I've been Googling this topic all day, but cannot seem to get my head around it. I want to set an API key on my website so that not just anybody can be querying my database. For the advertisement query, no parameters need to be sent from the client websites to my database. Can anyone offer some advice on how to do this?

Hello! First I would like to say welcome to the forums! I hope one day I'll be able to give back!!

Anyway, I seem to not know how to do this.  I'm creating a website for my guild, and I'm very very rusty with PHP (learned it a year or two back than lost it).  Anyway, I made the script to display the calendar portion of it (followed a tutorial), but I can't seem to import the feature to display events in the same cell as the date that its on.  Sorry my coding is a little sloppy but I'm hoping you guys can help xD  I left off with thinking that maybe i could use an array to do the job but I honestly have no clue how to go about this...

Code: [Select]

function calendar(){
include('connect.php');

$result = mysql_query($query);
