Need little PHP help - php

Question

I need little PHP help, here is a code which generate a product list:
<table class="list">
<?php for ($i = 0; $i < sizeof($products); $i = $i + 1) { ?>
<tr>
<?php for ($j = $i; $j < ($i + 1); $j++) { ?>
<td width="100%"><?php if (isset($products[$j])) { ?>
<a class="prod_snimka" href="<?php echo $products[$j]['href']; ?>"><img width="200" src="<?php echo $products[$j]['thumb']; ?>" title="<?php echo $products[$j]['name']; ?>" alt="<?php echo $products[$j]['name']; ?>" /></a>
<?php } ?></td>
<?php } ?>
</tr>
<?php } ?>
</table>
Output: http://d.pr/PPVq+
What I need to modify to produce output one TR and TD's inside, after 4 TD (products) make another TR. In one row I want 4 TD, in that case too, if there is only 3 product then the last one will be an empty TD. Huhh.. It is possible?
Thanks

Answer 1

It does not look like you need that inner loop. It will only execute once anyway.
Try this out:
<?php
$columns = 4;
$i = 0;
?>
<table class="list">
<?php foreach ($products as $product) {
if (!($i % $columns)) {
echo '<tr>';
} ?>
<td width="25%">
<a class="prod_snimka" href="<?php echo $product['href']; ?>"><img width="200" src="<?php echo $product['thumb']; ?>" title="<?php echo $product['name']; ?>" alt="<?php echo $product['name']; ?>" /></a>
</td>
<?php
$i++;
if (!($i % $columns)) {
echo '</tr>';
}
?>
<?php } ?>
<?php
if (!($i % $columns)) {
while (!($i % $columns)) {
echo '<td width="25%"></td>';
$i++;
}
echo '</tr>';
}
?>
</table>

<table class="list">
<?php $i = 0;
$cols = 4;
for each $products as $product {
if (!($i % $cols)) {
echo "<tr width='25%'>";
}
echo '<td><a class="prod_snimka" href="'.$product['href'].'"><img width="200" src="'.$product['thumb'].'" title="'.$product['name'].'" alt="'.$product['name'].'" /></a></td>';
if !($i % $cols) {
echo "</tr>";
}
$i++;
}
if ($i-1 % $cols) {
echo "</tr>";
}
