Question

I am trying to create a webpage that does a simple query of a table and displays the table to a page, but with one complex twist that has got me confused. Here are the column names and one example record from the table separated by commas:

R_ID ,  B_ID ,  R_No ,  RoomName , showers , eyewashPlumbed , EyewashBottles  
1 , 609 ,   609 ,   Hazardous Waste Shed ,  1   ,   1    ,  1

I need to print each row of this table, but also print multiple rows if either showers, eyewashPlumbed, or EyewashBottles is greater than 0. For example, I would print this row three times. If showers was 0 I would only print it two times (one for eyewashPlumbed, one for EyewashBottles, and 0 for showers). If showers was 2 I would print it 4 times, etc.

The code I’m using to print is as follows:

<?php while ($row = mysql_fetch_array($result, MYSQL_ASSOC)): ?> 
    <tr>
    <td><?php print $row["B_ID"];?></td> 
    <td><?php print $row["R_No"];?></td> 
    <td><?php print $row["RoomName"];?></td>
    <td><?php print $row["Showers"];?></td>
    <td><?php print $row["eyewashPlumbed"];?></td>
    <td><?php print $row["EyewashBottles"];?></td>  
    </tr>
<?php endwhile; ?>

The problem is that I don’t know how to interrupt the while loop in order to print the same row multiple times. It goes onto the next row as it pulls from the mysql_fetch_array.

You really should switch to PDO / mysqli, but with your current code it would be something like (for showers as in your example):

<?php
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)):
  $count = 2 + $row["showers"];
  for ($i = 0; $i < $count)
  {
?> 
    <tr>
    <td><?php print $row["Date"];?></td> 
    <td><?php print $row["Inspector1"];?></td> 
    <td><?php print $row["Inspector2"];?></td>
    <td><?php print $row["Building_Name"];?></td>
    <td><?php print $row["Room"];?></td>
    <td><?php print ($i + 1);?></td>  
    </tr>
<?php
  }
endwhile;
?>

You probably want to change $row["shower_no"] to something like $i + 1 as that column does not appear in your database.
