I have a block of PHP code that looks like this:
$flag = false;
if (empty($links))
{
echo '<h1>You have no uploaded images</h1><br />';
}
foreach ($links as $link)
{
$extension = substr($link, -3);
$image_name = ($extension == 'peg') ? substr($link, -15) : substr($link, -14);
($delete_submit) ? deleteImage('.' . $image_name, $link) : '';
echo '<div>';
echo '<table>';
echo '<tr><td class="fullwidth"><a class="preview_img" href="' . $link . '"><img src="' . $link . '" title="Click to enlarge" width="300" class="thumb" /></a></td></tr>';
echo '<tr><td><span class="default">Direct:</span> ';
echo '<input type="text" readonly="readonly" class="link-area" onmouseover="this.select();" value="' . $link . '" />';
echo '</td></tr>';
echo ($flag) ? '<hr /><br>' : '';
echo '</table>';
echo '<br>';
echo '</div>';
$flag = true;
}
I want the <div>
to include a different class based on if it is even or odd. If it is even, it gets X class, if it's odd it gets Y class.
How do I do this in my case? I'm totally clueless and I don't know how to start!
Initialise a variable $count=0;
before the loop. Then place the following in the loop: ++$count%2?"odd":"even"
.
$count = 0;
foreach ($links as $link)
{
$extension = substr($link, -3);
$image_name = ($extension == 'peg') ? substr($link, -15) : substr($link, -14);
($delete_submit) ? deleteImage('.' . $image_name, $link) : '';
echo '<div class="' . (++$count%2 ? "odd" : "even") . '">';
[...]
$i++;
echo '<div class="'.($i%2 ? 'odd':'even').'>';
[...]
