Hide table row if data doesn't exist - php

Question

I'll like to know if there is a code I could use to prevent table rows from forming if there is no data in the custom fields.
For example this is my table:
<tr>
<td><?php echo $place_1; ?></td>
<td><?php echo $person_1; ?></td>
<td><?php echo $status_1; ?></td>
<td></td>
</tr>
<tr>
<td><?php echo $place_2; ?></td>
<td><?php echo $person_2; ?></td>
<td><?php echo $status_2; ?></td>
<td></td>
</tr>
<tr>
<td><?php echo $place_3; ?></td>
<td><?php echo $person_3; ?></td>
<td><?php echo $status_3; ?></td>
<td></td>
</tr>
How can I make it that "if $place_2 is empty, hide all the table rows of 2 and 3?"
Any help is appreciated!

Answer 1

You could simply use PHP to only output the row when it is not empty:
...
</tr>
<?php if ($place_2 != "") { ?>
<tr>
<td><?php echo $place_2; ?></td>
<td><?php echo $person_2; ?></td>
<td><?php echo $status_2; ?></td>
<td></td>
</tr>
<?php } ?>
<tr>
...
This approach wraps the tr element in an if block. There are other many ways to achieve the same result, which may show up in other answers. Based on your question, it looks like you want to suppress $place_3 as well when $place_2 is empty. I assume $place_3 would be empty in this case, so you could apply the same approach to that tr element, substituting $place_2 with $place_3.

You can use a WHILE loop also . This will work for any number of rows. Simply replace 4 with number of rows to be checked in While condition
<?php
$i=0;
while($i<4)
{
if($place_.$i == "")
break; // if $place_ variable is empty no further rows are printed.
else
{
?>
<tr>
<td><?php echo $place_.$i; ?></td>
<td><?php echo $person_.$i; ?></td>
<td><?php echo $status_.$i; ?></td>
<td></td>
</tr>
<?php
} // closing bracket of else
$i = $i + 1;
} //end of while loop
?>
