Question

I have a PHP array that produces four columns per row of a table. I need to modify my php so I have eight columns per row instead of four.

For example. The current output looks like:

COL 1 COL 2 COL 3 COL 4
COL 5 COL 6 COL 7 COL 8
COL 9 COL 10 COL 11 COL 12
COL 13 COL 14 COL 15 COL 16

But I need it to look like this:

COL 1 COL 2 COL 3 COL 4      COL 5 COL 6 COL 7 COL 8
COL 9 COL 10 COL 11 COL 12   COL 13 COL 14 COL 15 COL 16          

On a previous question I asked if I could do this via CSS/HTML. It was strongly suggested that I modify my PHP code instead. I received the pseudo code to do this, but I’m having trouble getting it to work. The logic is as follows:

if($counter % 2 == 0)
    output startting <tr> tag

output the four <td> tags with data

if(($counter +1) % 2 == 0)
    output closing <tr> tag

Here is my current code:

            <form>
            <table>
                <?php $counter = 0;
                while ($counter < 20) : 
                $item = $set[$counter]
                                    if($counter % 2 == 0) ?>
                    <tr class="q<?php echo $counter; ?>">                   
                        <td><a class="question" href="<?php echo $item['qurl'] ?>');"><?php echo $item['q'] ?></a></td>
                        <td><input class="a1" type="text" name="a1" maxlength="3" size="3" /></td>
                        <td><input class="a2" type="text" name="a2" maxlength="3" size="3" /></td>
                        <td><input class="submit submit-<?php echo $counter; ?>" type="submit" value="Submit" /></td>
                                    <?php if(($counter +1) % 2 == 0) ?>
                    </tr>
                <?php $counter++; ?>
                <?php endwhile; ?>
            </table>
                            </form>

I’m a beginner so please excuse my novice attempt. Thanks in advance.

You should really check out the syntax for the PHP if statement .

$counter = 0;
while ($counter < count($set)) : 
    $item = $set[$counter];
    if($counter % 2 == 0): ?>
        <tr class="q<?php echo $counter; ?>">                   
    <?php endif;?>
            <td><a class="question" href="javascript:soundManager.play('<?php echo $item['qurl'] ?>','audio/part2/type1/type1_<?php echo $item['qurl'] ?>.mp3');"><?php echo $item['q'] ?></a></td>
            <td><input class="a1" type="text" name="a1" maxlength="3" size="3" /></td>
            <td><input class="a2" type="text" name="a2" maxlength="3" size="3" /></td>
            <td><input class="submit submit-<?php echo $counter; ?>" type="submit" value="Submit" /></td>
    <?php if(($counter +1) % 2 == 0): ?>
        </tr>
    <?php endif;?>
    <?php $counter++; ?>
<?php endwhile; ?>
<?php if(($counter +1) % 2 == 0): ?>
    </tr>
<?php endif; ?>
