Question

This is for a timetable and what it does is displays the previous day’s timetable and who has booked each slot (this is for a radio station.)

At the moment it displays who has booked each slot in chronological order however I would like it to say the time next to each result. The query outputs 24 rows (which is from Midnight to 23:00) and next to each slot I would like it to say (00:00, 01:00, 02:00, 03:00… 21:00, 22:00 so on so forth.)

This is my current code:

<?php 
include("../config.php");

#// Timetable Clearup Variabls
$yesterday = strtotime('yesterday');
$yesterdow = date('l',$yesterday);

echo "<table width=\"580px\" class=\"board\" border=\>";

$order = "SELECT * FROM timetable WHERE day = '$yesterdow'";
$result = mysql_query($order);

// Error checking
if (!$result) {
  // output error, take other action
}
else {
  while ($row=mysql_fetch_array($result)){
     // Append all results onto an array
     $rowset[] = $row;
  }
}
    foreach ($rowset as $row) {
  echo "<tr><td>" . htmlspecialchars($row['username']) . "</td></tr>";
}



?> 

Can you help?

I think we’re all looking too hard at a VERY simple problem. You are already using SELECT * in your query, so you’re already fetching all three columns from your table. So now, all you need to do is add another cell to each row of your table.

echo "<tr><td>" . htmlspecialchars($row['username']) . "</td><td>" . htmlspecialchars($row['time']) . "</td></tr>";

And to make sure you are fetching your rows in the correct order, you should add an ORDER BY to your query:

SELECT * FROM timetable WHERE day = '$yesterdow' ORDER BY time

If you don’t specify an ORDER BY clause, you have no guarantee that you will get the results in any particular order.

And one last thing, you are looping through the rows twice, unnecessarily. Get rid of the foreach loop and put the echo directly inside the while loop.
