PHP - Simple Maths

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 />

Have tried to do this myself all day now and i`m getting a little frustrated now.

I have a contact form with a select box which can have multiple options selected, i`m using formmail.php to process the info. Problem is I have forgot how to list the values within the array and format them within the email body.

$licences is the multiple select box

any help would be gratefully received!!
 
Code: [Select]
<?php
  $name=addslashes($_POST['name']);
  $email=addslashes($_POST['email']);
  $town=addslashes($_POST['town']);
  $phone=addslashes($_POST['phone']);
  $licences=addslashes($_POST['licences']);
  $message=addslashes($_POST['message']);

 // you can specify which email you want your contact form to be emailed to here

  $toemail = "admin@mysite.com";
  $subject = "Question : mysite.com";

  $headers = "MIME-Version: 1.0\n"
            ."From: \"".$name."\" <".$email.">\n"
            ."Content-type: text/html; charset=iso-8859-1\n";

  $body = "Name: ".$name."<br>\n"
            ."Email: ".$email."<br>\n"
            ."Town/City: ".$town."<br>\n"
            ."Phone: ".$phone."<br>\n"
            ."Interested in Licence/s: ".$licences."<br>\n"
            ."Message:<br>\n"
            .$message;

  if (!ereg("^[a-zA-Z0-9_]+@[a-zA-Z0-9\-]+\.[a-zA-Z0-9\-\.]+$", $email))
  {
    echo "That is not a valid email address.  Please return to the"
           ." previous page and try again.";
    exit;
  }

    mail($toemail, $subject, $body, $headers);
    echo "Thanks for submitting your message.";
?>

I am trying to write a PHP page that takes an XML file stored on an external server, parses it, and rewrites the data to a new XML file formatted to my liking.  The feed is for events and has about 250 events to parse.  The problem is that if one event has an empty node, the script will use the same event data for the node used previously.  Upon research, I see that empty nodes are parsed as an empty SimpleXMLElement Object. See my code for example:

XML Original:
Code: [Select]
<event_info>
<event id="1222209">
                <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score>
<quotes></quotes>
<radio>102.9 FM</radio>
<sched_opp><![CDATA[Toledo]]></sched_opp>
        </event>
<event id="1222210">
                <outcome_score><![CDATA[]]></outcome_score>
<quotes></quotes>
<radio>107.1 FM</radio>
<sched_opp><![CDATA[Ohio]]></sched_opp>
        </event>
</event_info>

Output XML (note <outcome_score> on second event):
Code: [Select]
<event_info>
<event id="1222209">
                <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score>
<quotes></quotes>
<radio>102.9 FM</radio>
<sched_opp><![CDATA[Toledo]]></sched_opp>
        </event>
<event id="1222210">
                <outcome_score><![CDATA[L, 1-0 (OT)]]></outcome_score>
<quotes></quotes>
<radio>107.1 FM</radio>
<sched_opp><![CDATA[Ohio]]></sched_opp>
        </event>
</event_info>


PHP code:

$xml = simplexml_load_file($source);
echo "<event_info>"; 
foreach($xml->event as $event) {
        echo "<event>";
        if($event->outcome_score != '') { echo "<outcome_score><!CDATA[{$event->outcome_score]]></outcome_score>"; }
        if($event->quotes != '') { echo "<quotes><!CDATA[{$event->quotes]]></quotes>"; }
}
        if($event->radio != '') { echo "<radio><!CDATA[{$event->radio]]></radio>"; }
        if($event->sched_opp != '') { echo "<sched_opp><!CDATA[{$event->sched_opp]]></sched_opp>"; }
        echo "</event>";
}
echo "</event_info>";


Basically, whenever an event has no outcome score, the most recent outcome score is repeated for all events after.  Any help would be greatly appreciated!  Thanks!

I think I'm using simple xml wrong

I'm trying to read strings of xml and get it to list the "attributes" in the strings but it's not working. 

How would I read and list the attributes of this string
<Address><to>Joshua</to><from>Rockhampton</from><country>Australia</county></Address>

It needs to out put a string that can be printed and look like (or something like)

to:Joshua
from:Rockhampton
country:Australia

All my code produces errors and the page just goes blank and I don't know what is wrong.l

Hi Guys   I'm updating my website and I'm stumped on the last section.

I have a dynamic Table with various fields showing from Mysql, I use MS Access as a front end, and I have a field named Download, I enter the file location of a customers invoice and it stores the link in mysql, works perfectly. BUT, the dynamic table looks like this:

Download - \users\MM4512\Invoices\Invoice23.PDF which is hyperlinked so they can download it etc.. Is there a way I can change this section from the above to a simple (Download Invoice) instead of all that text?

The code used is :
 

<td><a href="<?php echo $row_Invoices['download']; ?>" target="_blank"><?php echo $row_Invoices['download']; ?></a></td>

Im trying to parse this xml but i can get it to output a simple string, can someone see what im doing wrong??

Code: [Select]
$str = "<channel><item>
<id>cb-uA4QHmpDxYdpgW1jPwiYsUwjBViwlinS</id>
<title>Rules of Engagement - Play Ball Extended Preview - Season 5 - Episode 12</title>
</item>
</channel>";


$n_data = new SimpleXmlElement($str, LIBXML_NOCDATA);
foreach ($n_data->channel->item as $d) {
$vid = $d->id;
$title = $d->title;

print_r($d->title); //testing
die(); //testing
$arr2[] = array('vid' => $vid, 'title' => $title, 'site_id' => 10 ,'time' => 456);
}
The print_r() returns
Code: [Select]
SimpleXMLElement Object
(
    [0] => Rules of Engagement - Play Ball Extended Preview - Season 5 - Episode 12
)
If i simply echo $d->title it returns a string, but i need to reapply $d->title to another array as shown above

Hi all - I have a simple PHP app, which I've run thru my Dreamweaver validation and a few PHP syntax validators and it comes out clean. Works perfectly in Firefox but shows a blank page in I.E. and I'm not sure why. The functionality is simple - the page shows a disclaimer, and when the user hits 'OK" it should hide the disclaimer and then display other content. Here's the URL:

https://www.dca.ca.gov/webapps/bppe/annual_report.php

Any ideas as to what is wrong? Thanks! 

Here's the code:

<?php
        if(isset($_POST['OK'])){
