Hi Experts,

I have this php code:

    <?php

$catTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent'=> 28)); ?>

<?php foreach($catTerms as $catTerm) : ?>

       <td><a href="/product-category/<?php echo $catTerm->slug; ?>"><?php echo $catTerm->name; ?></a></td>

<?php endforeach; ?>     

Open in new window


I need it to output two <td> every one <tr> like this

<tr>
        <td></td>
        <td></td>
      </tr>

Open in new window


I cant seem to get a solution - please help!

Many thanks in advance

I havent explained myself very well... This just outputs the same array value side by side.

I want to loop through the whole array putting every two values into a row...

the output should be...
<tr>
        <td><a href="/product-category/value1">Value1</a></td>
        <td><a href="/product-category/value2">Value2</a></td>
      </tr>
      <tr>
       <td><a href="/product-category/value3">Value3</a></td>
        <td><a href="/product-category/value4">Value4</a></td>
      </tr>

If you're looking to place the results in two columns, you'd be better off with a for loop.
<?php

$catTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent'=> 28)); ?>

<?php for($i = 0; $i < count($catTerms); $i += 2) : ?>

       <tr><td><a href="/product-category/<?php echo $catTerms[i]->slug; ?>"><?php echo $catTerm->name; ?></a></td>

       <td><a href="/product-category/<?php echo $catTerms[i+1]->slug; ?>"><?php echo $catTerm->name; ?></a></td></tr>

<?php endfor; ?>

Open in new window


However, this will only work if you have an even number of items. If you have or may have an odd number, you'd need to use an if statement for the second <td>.
<?php

$catTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent'=> 28)); ?>

<?php for($i = 0; $i < count($catTerms); $i += 2) : ?>

       <tr><td><a href="/product-category/<?php echo $catTerms[i]->slug; ?>"><?php echo $catTerm->name; ?></a></td>

<?php if ($i + 1 < count($catTerms) ) { ?>
       <td><a href="/product-category/<?php echo $catTerms[i+1]->slug; ?>"><?php echo $catTerm->name; ?></a></td>

<?php } ?>

       </tr>

<?php endfor; ?>

This is the approach I typically use. It lets me easily change the # of columns per row later if I ever need to (just change $columnsPerRow to the desired number) and the code is very readable.

<?php
$catTerms = get_terms('product_cat', array('hide_empty' => 0, 'orderby' => 'ASC', 'parent'=> 28)); ?>
$currentColumn = 0;
$columnsPerRow = 2;

<tr>
<?php foreach($catTerms as $catTerm) : ?>
       $currentColumn++;
       <td><a href="/product-category/<?php echo $catTerm->slug; ?>"><?php echo $catTerm->name; ?></a></td>
        <?php 
        // Start a new row every $columnsPerRow
        if(($currentColumn % $columnsPerRow) == 0)
        {
          echo "</tr><tr>";
        }
        ?>
<?php endforeach; ?>  
</tr>

@honestman31: Use the % operator. It's a much cleaner and more efficient way to do exactly what you're doing:

Multiple math operations and intval() casting:
if( $counter/2 == intval($counter/2) )

One math operation:
if( ($counter % 2) == 0)

Or for even shorter syntax:
if(!($counter % 2))
0
