I am very new to PHP and slowly learning. I had someone help me with the code below but need a tweak on the formatting side.

Currently it displays like this:

October 2008
   Event
   Date, Day of week, time, Location, tickets

   line

   Event
   Date, Day of week, time, Location, tickets

I would like it to change to display like this
October 2008
Day of week, Date (Friday, 3rd)
   Event - Time - Location - Tickets
   Line
   Event - Time - Location - Tickets
   Line
Day of week, Date (Saturday, 4th)
 Event - Time - Location - Tickets
   Line
   Event - Time - Location - Tickets
   Line

<?php
	$currentdate = date('Y-m-d');
 
	$event_query = "SELECT * FROM Events WHERE Date >= NOW() AND Date <= DATE_ADD(NOW(), INTERVAL 1 MONTH) ORDER BY Date LIMIT 15;";
	$event_query_result = mysql_query($event_query);
	
	$CurrentMonth = "";
	$CurrentYear = "";
	$first_time = 1;
	
	if (mysql_num_rows($event_query_result) == 0)
	{
		echo "No current events found\n";
	}
	else
	{
		while ($event_row = mysql_fetch_assoc($event_query_result))
		{
			$event_name = $event_row['Name'];

Here's some notes to clean up your code.

You don't need to
$event_name = $event_row['Name'];        
$event_dates = $event_row['Date'];
for all the fields. Just change the
$event_row = mysql_fetch_assoc...
to
$event = mysql_fetch_assoc...
then you can reference the fields as $event['date']

next convert this
echo "<td colspan=\"2\" class=\"style18\"><a href=\"display_event.php?id=$event_id\">$event_name</a></td>\n";
            echo "<td width=\"22%\"> </td>\n";
to
echo "<td colspan=2 class='style18'><a href='display_event.php?id=".$event['ID']."'>".$event['Name']."</a></td>\n";
            echo "<td width='22%'> </td>\n";
Note, html will accept single quotes, this cleans up your php. Also html does not require quotes around numberic values like colspan. It does require quotes on width in percentages but not in pixels

Hope this isn't too confusing.

Enjoy


//outside the loop
        $TitleDate = "";
 
 
 
                while ($event = mysql_fetch_assoc($event_query_result)) // Just call it $event
                {
                        
                        if ($TitleDate != $event['date']) // check to see if the date has changed
                        {
                                if ($TitleDate != "" ) // use this instead of $first_time
                                {
                                        echo "</tr>\n";
                                        echo "</table>\n";
                                        echo "<p class=\"style18\"></p>\n";
                                }
                                
                                echo "<p class=\"style2\">".date("l, M jS",strtotime($event['date'])) ."</p>\n";
                                echo "<table width=\"100%\" border=\"0\" cellspacing=\"0\">\n";
                                
                                $TitleDate = $event['date'];

I am not sure what to change and where. You wrote up that code, but what do I replace?

Ok, sorry I probably was throwing too much at you at once.

Let's start with this code. it sets up $TitleDate and will display every date change.
<?php
        $currentdate = date('Y-m-d');
 
        $event_query = "SELECT * FROM Events WHERE Date >= NOW() AND Date <= DATE_ADD(NOW(), INTERVAL 1 MONTH) ORDER BY Date LIMIT 15;";
        $event_query_result = mysql_query($event_query);
        
        $TitleDate = "";
        $first_time = 1;
        
        if (mysql_num_rows($event_query_result) == 0)
        {
                echo "No current events found\n";
        }
        else
        {
                while ($event_row = mysql_fetch_assoc($event_query_result))
                {
                        $event_name = $event_row['Name'];         
                        $event_dates = $event_row['Date'];    
                        $display_date = date("M j, Y", strtotime($event_dates ));        
                        $event_time = $event_row['DisplayTime'];    
                        $event_tickets = $event_row['Tickets'];        
                        $event_id = $event_row['ID'];
                        $event_location = $event_row['Location'];
                        $eventCode = $event_row['EventCode'];
                        $seasonCode = $event_row['SeasonCode'];
                        $OnSale = $event_row['OnSale'];

                        if ($TitleDate != $event_dates)
                        {
                                if (!$first_time)

I think you're referring to these lines of code

            echo "<td width=\"15%\" class=\"style3\">$EventDayOfMonth</td>\n";
            echo "<td width=\"24%\"><span class=\"style3\">$EventDayOfWeek</span></td>\n";

you could just change them to

            echo "<td width=\"15%\">&nbsp;</td>\n";
            echo "<td width=\"24%\">&nbsp;</td>\n";

If you were to remove these lines you'd have to recalculate the widths of the remaining columns to have them add up to 100% and also look for the colspan= lines and adjust them for 2 less columns.

re: "I need Event name and location and time in the same row."

Do you still want things aligned in table columns? Or, just one line of text per event?

ie

Oct. 08
Thursday 2nd
Event Name Location Time Tickets
Event Name Location Time Tickets

Oct. 09
Friday 3rd
Event Name Location Time Tickets
