PHP - How Do You Write A Simple Listener Script?

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 />
<input name="myBtn" type="submit" value="Log In" />
</form>

I am writing a listener to handle IPN notifications from paypal, and one thing I cant seemt o find anywhere -

How does IPN handle pending payments, that are then completed/denied? For example, if paypal invokes my IPN once the payment is made, but pending, with a particular transaction ID, when the payment completes, does it then invoke my IPN again, with the payment status as 'completed'? If so, will this second IPN have the same transaction ID?

It would seem logical that the same transaction ID is sent again, as it is actually the same customer transaction, however reading this on thepaypal website suggests otherwise:

"Avoid duplicate IPN messages. Check that you have not already processed the transaction identified by the transaction ID returned in the IPN message. You may need to store transaction IDs returned by IPN messages in a file or database so that you can check for duplicates. If the transaction ID sent by PayPal is a duplicate, you should not process it again. "

Help would be appreciated!!

I am trying to write a Paypal IPN Listener that will create a confirmation key in the order database I have on the server. Upon completing the order it will then send a email to the buyer with a link to a file upload page with the confirmation code embedding so that when the buyer goes to the upload page it can authenicate based on that code prior to allowing the person to upload a file. I has been a pain and is still not working. Similar to an email confirmation when some one signs up as a user on a site, but using the Paypal order information and the listener to generate the confirmation and authentication. IS THIS POSSIBLE?

I am VERY VERY green to PHP. I feel like a fish out of water.

I need to create a simple SOAP listener in PHP. This site need not do anything with the SOAP message but send it to another web app within our clients network. The reason for this long winded and exceeds the scope of this request.

Our client only has one Apache server exposed to the public internet so I cannot use .NET and IIS.  All other web servers are internal and running IIS.

The SOAP messages will be coming from SalesForce.  They have a plethora of information on doing this in .NET and IIS but not PHP.

Can anyone point me in a 'PHP for dummies' way?

Thanks in advance.

My favourite bands a
<ul>

<?php

// define arrays
$morebands = array('Desturbed', 'Anthrax');
$artists = array('Metallica', 'Evanescence', 'Linkin Park', 'Guns n Roses', "$morebands");
// loop over it
// print array elements
foreach ($artists as $a) {
    if ($a != 'Array'){
   echo '<li>'.$a;
}
   Else {
foreach ("${$a}" as $b){
echo '<li>'.$b;
}
}
}

?>

</ul>
</body>
</html>

I can not figure out why this will not work:(
I would like the foreach to run through the array as normal, but if it encounters a nested array, loop it as well.

I know this likely is not the right, or best way to do this, but I am just learning PHP through a tutorial and I learn best by doing... So I take the lessons, make them more complicated, then figure out how to make it happen (like so).

right now I am working on

anyhow thanks for any help!

This is more of a Paypal question, but I'm using php on the listener and hopefully someone has run into this problem.  I'm having trouble finding the correct POST name to use to get the OPTION SELECT for the item on my listener page.

I tried:

$option = $_POST['os0'];

But, I'm not getting anything using that. I've also tried os0_x, on0, and on0_x.

This is what I'm posting to Paypal:

<input type="hidden" name="on0" value="Term">
<select name="os0">
<option value="1 Year">1 Year</option>
<option value="3 Years">3 Years</option>
<option value="5 Years">5 Years</option>
</select>

Good evening guys and gals,

for some reason I cant get my head around something quite simple, basically I am trying to work out a way of simply recording referrals to my site when the potential user registers.

This worded example is basically what I want:

registered user a with a username of smithy invites his friend western to become a member of a site he has joined:

I guess here I would basically use something like mysite.com?refid=smithy as the link he gives he's friend

Now this is where my brain refuses to work, what if western decides to have a look around the site before he decides to register and clicks on a few internal pages? Obviously the referral id will no longer be in the address bar.

So my 1st question is, how can I check to see if a referral is used when accessing the site? I could then store the username in a session or cookie.

If I had something like this:

<?php

$refid = $_GET('refid')

setcookie("user", $refid, time()+3600);
?> 

But how would I check that a refid exists in the url so it doesnt throw up a parse error?

I have more questions but 1 thing at a time!

Many Thanks

Hiya!

I need to create a simple PDF script that will always create A4 documents. I need the content to be controlled using HTML and CSS.

Where do you start in creating such a script?

Any help is greatly received.

Hi everybody, my goal is to get the IP of someone accesing the site, writing the time and date along with his IP into the database. Of course, I would be adding the script to my frontpage when I make it work.
But I get this error:
Quote


Parse error: syntax error, unexpected T_VARIABLE in D:\Program Files\xampp\xampp\htdocs\script1.php on line 8

I've checked line 8, I dont find anything in it that is out of place.
Here is the code:


<?php 
$ip = $_SERVER['REMOTE_ADDR'];
$date = date("m.d.y"); 
$time = time();
mysql_connect ("localhost", "root", "********") or die ('Error: '. mysql_error());
mysql_select_db ("ip");

$query = "INSERT INTO ipdo (time, date, ip) VALUES ('"$time"', '"$date"', '"$ip"')";
mysql_query($query) or die ('Error updating database');

echo "Database updated with: " .$ip. "" ; 
?>


This is the first script I write entirely on my own, so be gentle 
Help?

The attached script does everything I want it to do, but it's not very elegant.  I could use some help cleaning it up.  Any and all help is greatly appreciated.

Thanks!!!

Hi all, Im coding a simple script for my website which just changes the users rank.

$username=$_SESSION['username'];

$get = mysql_query ("SELECT * FROM users WHERE username = '$username'");
$fetch = mysql_fetch_object($get);

if ($fetch->userlevel >= "2"){
$newrank = $_POST['newrank'];
$user1 = $_POST['user'];
if (strip_tags($_POST['update'])){
mysql_query("UPDATE users SET `rank` = '$newrank' WHERE username='$user1'") or die (mysql_error());
echo ("You have updated $user1's rank to $newrank !");
}
}
else{
echo ("Your userlevel isnt high enouth to be here!");
}
?>

But there seems to be something wrong with that code, which I carnt see or work out. When I click Update submit button it does nothing, but can anyone see why it does nothing?

Thanks.

I've tried Googling this for a long time but I only find complete member systems with ugly code, not something i'm looking for.

What I am looking for is just a simple tutorial or commented code to make a admin login.

What it's going to do is just:

Loading a MD5 salt hasched password from my MYSQL database.
You'll get to fill in one field: Password. If it validates with the MYSQL password it'll show the hidden content; if not it'll just give a "not correct error".

That's basicly it. I have only one page of secret admin stuff so yeah.. it would be awesome to have the ability to logout and I of curse want to have everything in sessions!

It would be to big help!

There is a sql query happening if the item is not empty, what I NEED and can not seem to figure out is to re run the rand() function. The server is PHP 4 so it is not possible to use the goto statement... That would be to easy. So any help would be great... Here is the code... the script running after the script finds a empty sql row is ot included... it works... just this one part does not.

Code: [Select]
<?php
$connection = mysql_connect(CREDENTIALS REMOVED) or die(mysql_error());
   mysql_select_db("testingblock", $connection)or die(mysql_error());

  
   $random_num = rand(1,10); 
  
if($random_num == 1){
   $query = sprintf("SELECT email FROM access_codes WHERE id='1'", 
mysql_real_escape_string($email)); 

$result = mysql_query($query); 
$row = mysql_fetch_assoc($result);

if(!empty($row['email'])){
