[RESOLVED] Alternating Row Styles

[rsmith]

Hey all,
I have a small snippet of code that dynamially adds rows to a table. The hang I'm up having is in setting the class of each row so that the rows alternate color. here's the script:

		             	++$x;
                             if($x % 3 == 1){
                                 ++$y;
                             }

                         if($y % 2 == 1) {
                             $row_style = "d0";
                         }else{
                             $row_style = "d1";
                         }

                         echo "<tr class='".$row_style."'>";

                         	 echo "<td valign='middle' width='200'>Cell Data Goes Here</td>";

                         if($x % 3 == 0){
                             echo "</tr>";
                         }

The problem is that it prints the row contents fine but will use d0 for the first 3 results, d1 for the next 3, and back and forth in groups of 3. Any Ideas?

TIA!

It is hard to say without knowing just was is $x and $y and the overall picture of the loop, but my guess is that you are retrieving cell by cell, and then alternating based on the cell instead of the row. You should only switch row style when you begin a new row.

[rsmith]

$x and $y are only used for the loop. I know that it only should be switching styles when it creates a new row. My problem is I can't get the current code to that point.

[laserlight]

I suggest showing the entire code for generating the table. Try and simplify it so that it shows the actual problem, of course.

this should work

$x = 1;
loop
	if ($x <= 3) { 
		$row_style = 'd0';
	} else { 
		$row_style = 'd1';
	} 

echo '<tr class="' . $row_style . '">'; 
echo '<td valign="middle" width="200">'. $cell_data . '</td>'; 
echo '</tr>'; 

if ($x > 5) { 
	$x = 0; 
} 
$x++;
end loop

EDIT- wait im confused, is it not supposed to alternate every other row?

[rsmith]

Well I took a guess and reworked it as follows which now alternates the tables but for some reason is ignoring the limit clause I have for my pagination. That's a separate issue so this one is resolved.

++$x;
                              if($x % 2 == 1){
                                  ++$y;
                                  if($y % 2 == 1) {
                                      $row_style = "d0";
                                  }
                                  else {
                                      $row_style = "d1";
                                  }
                                  echo '<tr class=' . $row_style . '>';
                             	  echo "<td valign='middle' width='200'>Cell 1</td><td valign='middle' width='200'>Cell 2</td>";
                         	  }

                         if($x % 2 == 0){
                             echo "</tr>";
                         }
                   }

this one alternates every other row, that alternates every 3 rows

loop 
	if ($x) {
		$row_style = 'd0'; 
		$x = 0;
	} else {
		$row_style = 'd1'; 
		$x = 1;
	}

echo '<tr class="' . $row_style . '">'; 
echo '<td valign="middle" width="200">'. $cell_data . '</td>'; 
echo '</tr>'; 
end loop

[foyer]

why do you have the </tr> in an if statement? you will end up with an HTML error because the start of the row <tr class> is not be checked the same way.

[rsmith]

the $x relates to the number of table cells, in my case, 2. when the value of $x divided by itself is 0 then it needs to close the table row and start over.

hmm... is this resolved or is it not? If it is a new problem, starting a new thread would be better.

[rsmith]

I got the alternating resolved. the issue is with pagination at this point and I will start a new thread. Thanks!
