我正试图获得一个按降序显示帖子的页面（在Wolf CMS上），我认为我使用"if"语句的方式破坏了代码。如果我删除第一个，页面显示良好，但顺序不正确。它将按升序显示。这是我的代码，有人能发现我的功能障碍吗？：
<?php $findTag = 'dinorun';
$mychildren = $this->findById(4)->children();
if ($mychildren->childrenCount() > 0) {
$last_articles = $mychildren->children(array('limit'=>10, 'order'=>'page.created_on DESC'));
foreach ($last_articles as $child) :
$childTags = join(',', $child->tags());
if (strpos($childTags, $findTag) !== FALSE) :
?>
<ul class="blogpage">
<?php echo $child->content();
echo "<div class='postend'></div></ul>"; ?>
<?php endif; ?>
<?php endforeach;
?>
编辑：实际上我没有多余的；那是个错误。移除它并没有改变。
这是我使用的原始代码，它以升序显示所有内容：
<?php $findTag = 'dinorun'; ?>
<?php $children = $this->findById(4)->children(); ?>
<ul class="blogpage">
<?php foreach ($children as $child) : ?>
<?php $childTags = join(',', $child->tags()); ?>
<?php if (strpos($childTags, $findTag) !== FALSE) : ?>
<?php; echo $child->content();
echo "<div class='postend'></div></ul>"; ?>
<?php endif; ?>
<?php endforeach; ?>
您需要将分号删除到
试试这个
<?php $findTag = 'dinorun';
$mychildren = $this->findById(4)->children();
if ($mychildren->childrenCount() > 0) {
$last_articles = $mychildren->children(array('limit'=>10, 'order'=>'page.created_on DESC'));
foreach ($last_articles as $child) :
$childTags = join(',', $child->tags());
if (strpos($childTags, $findTag) !== FALSE) :
?>
<ul class="blogpage">
<?php echo $child->content();
echo "<div class='postend'></div></ul>"; ?>
<?php endif; ?>
<?php endforeach;
?>
试试这个代码，
<?php $findTag = 'dinorun'; ?>
<?php $mychildren = $this->findById(4)->children();
if ($mychildren->childrenCount() > 0) {
$last_articles = $mychildren->children(array('limit'=>10, 'order'=>'page.created_on DESC'));
?>
<?php foreach ($last_articles as $child) : ?>
<?php $childTags = join(',', $child->tags()); ?>
<?php if (strpos($childTags, $findTag) !== FALSE) : ?>
<ul class="blogpage">
<?php
echo $child->content();
echo "<div class='postend'></div></ul>";
?>
<?php endif; ?>
<?php endforeach; ?>
<?php }?>
