我正在尝试为每个LI foreach提供一个替代课程。
即
<li class="odd">
text
</li>
<li class="even">
text
</li>
<li class="odd">
text
</li>
<li class="even">
text
</li>
这是我的代码:
<ul>
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php if($extraField->value): ?>
<li class="<?php echo ($key%2) ? "odd" : "even"; ?> type<?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
Text here
</li>
<?php endif; ?>
<?php endforeach; ?>
</ul>
请任何人帮忙...... 感谢

尝试:
<?php $count = 0; // need to set first value
<?php foreach ($this->item->extra_fields as $key=>$extraField): ?>
<?php if($extraField->value): ?>
<li class="<?php echo (++$count % 2) ? "odd" : "even"; ?> type <?php echo ucfirst($extraField->type); ?> group<?php echo $extraField->group; ?>">
Text here
</li>
<?php endif; ?>
<?php endforeach; ?>

我会这样做..它是关键独立的,你最好看看李级的样子。
<ul>
<?php
foreach ($this->item->extra_fields as $key=>$extraField) {
if($extraField->value) {
$toggle = ($toggle=="odd"?"even":"odd");
echo '<li class="',$toggle,' type',ucfirst($extraField->type),' group', $extraField->group,'">';
echo 'Text here';
echo '</li>';
}
}
?>
</ul>
