How to display dynamic data based on MySQL entries?

Hi all,
I am attempting to create an alert display monitor. The admin interface allows me to add the following fields to mysql:
 id  date  time  location  description  severity  publish

Publish is meant as an on/off switch to turn the display on or off.
Here is a dump of mysql table
----------------------
--
-- Table structure for table `outages`
--

CREATE TABLE IF NOT EXISTS `outages` (
  `id` int(11) NOT NULL auto_increment,
  `date` date NOT NULL,
  `time` time NOT NULL,
  `location` varchar(50) NOT NULL,
  `description` text NOT NULL,
  `severity` varchar(50) NOT NULL,
  `publish` varchar(5) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=7 ;

--
-- Dumping data for table `outages`
--

INSERT INTO `outages` (`id`, `date`, `time`, `location`, `description`, `severity`, `publish`) VALUES
(1, '2009-07-10', '09:41:00', 'Charlotte', 'test 1', 'Low', 'N'),
(2, '2009-07-13', '08:00:59', 'Jacksonville', 'Test Red', 'Urgent', 'N'),
(3, '2009-07-13', '08:01:16', 'Jacksonville', 'Test Orange', 'High', 'Y'),
(4, '2009-07-13', '08:01:33', 'Jacksonville', 'Test Yellow', 'Medium', 'Y'),
(5, '2009-07-13', '08:01:47', 'Jacksonville', 'Test Blue', 'Low', 'Y'),
(6, '2009-07-13', '08:02:00', 'Jacksonville', 'Test Green', 'No Issues', 'Y');
----------------------
and in the code I have put my test query page.
What I want, is to do a loop through the records and print the last active alert. What is the best way to accomplish this? The way the code is right now, all it echos is the first record, even if I change the publish parameter.

Thanks for the help

Try this.
<?php require_once('Connections/conUDS.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }
 
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
 
  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":

ok, that displays the 4 records of 6 in the database maked as publish="Y", but it doesn't differential between the different typs of alerts. (Urgent, High, Medium, Low)
Here is a picture of the output.

If I change the code like this, I get al of them to post.

  }
 
  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

Yes, didn't check the wrong single "=" compare statements, sorry.

the line "if ($row_rsBulletins['publish'] == "Y")" is also useless, since this is already filtered by the SQL query.

To have the "There are no published alerts." you need to do something like this :

$query_rsBulletins = "SELECT * FROM outages ORDER BY date DESC LIMIT 10"; /* 10 last published, for example */ 
$rsBulletins = mysql_query($query_rsBulletins, $conUDS) or die(mysql_error());
 
$totalRows_rsBulletins = mysql_num_rows($rsBulletins);
 
if($totalRows_rsBulletins > 0)
{
	while($row_rsBulletins = mysql_fetch_assoc($rsBulletins))
	{
		if ($row_rsBulletins['severity'] == "Urgent") {
        	echo "<div id=\"urgent\">I am a red alert!</div>";
		}
    	else if ($row_rsBulletins['severity'] == "High") {
        	echo "<div id=\"high\">I am a orange alert!</div>";
    	}
    	else if ($row_rsBulletins['severity'] == "Medium") {
       		echo "<div id=\"medium\">I am a yellow alert!</div>";
     	}
   		else if ($row_rsBulletins['severity'] == "Low") {
     		echo "<div id=\"low\">I am a blue alert!</div>";
		}
		else {
			echo "<div id=\"allgreen\">There are no reported outages.</div>";
		}
	}
}
else
{
	echo "<div id=\"allgreen\">There are no published alerts.</div>";
}

I'd say you above response is close. I just made a small change to add the WHERE statement to the query, and I pulled the 1st else statement.
This seems to be giving me the desired look.
Thanks Flob9!

<?php
mysql_select_db($database_conUDS, $conUDS);
$query_rsBulletins = "SELECT * FROM outages WHERE publish = 'Y' ORDER BY date DESC LIMIT 10"; /* 10 last published, for example */ 
$rsBulletins = mysql_query($query_rsBulletins, $conUDS) or die(mysql_error());
 
$totalRows_rsBulletins = mysql_num_rows($rsBulletins);
