Printing a Record multiple times in PHP and MySql - php

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.

Answer 1

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.

Answer 2

If you have a variety of rules
I would handle this problem like this:
<?php
function printRow($row=array(), $times=1) {
for($i=0; $i<$times; $i++) {
echo "
<tr>
<td>{$row["Date"]}</td>
<td>{$row["Inspector1"]}</td>
<td>{$row["Inspector2"]}</td>
<td>{$row["Building_Name"]}</td>
<td>{$row["Room"]}</td>
<td>{$row["shower_no"]}</td>
</tr>
";
}
}
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
switch(true) {
case ($row['eyewashPlumbed']>0 or $row['EyewashBottles']>0):
printRow($row, 3); // print 3 times
break;
case ($row['showers']==0): // print 2 times
printRow($row, 2);
break;
default: // default print 1 time only
printRow($row, 1);
}
}
?>
