我正在使用CakePHP创建一个网站。在我的主页上,我想显示六个最新视频和六个最受欢迎的视频。我创建了一个名为'itemList'的元素,我传递了一个类型参数和一个带有items的数组。
我使用以下代码获取最新视频:
$this->element('itemList', array('type' => "video", 'items' => $latestVideos));
echo $this->fetch('itemList');
以下代码为热门视频:
$this->element('itemList', array('type' => "video", 'items' => $popularVideos));
echo $this->fetch('itemList');
最新视频会按照应有的方式显示,但热门视频会先显示最新视频(第二次)以及之后的热门视频。
有没有人知道如何“清除”或“取消设置”第一个itemList元素,在第二次使用它时开始使用空元素?
<?php
/* The following parameters are set when this element is called upon:
* $type: article, video
* $items: the list with items to be displayed
*/
$this->start('itemList');
echo $this->Html->script('equalColumns');
$itemCount = 0;
$mainType = $type;
$listType = null;
// If the article list is called, use wider columns css (.articleList)
if ($type == "article") {
$listType = " articleList";
}
?>
<ul class="otherArticles<?php print($listType); ?>">
<?php
foreach ($items as $item) {
$duration = null;
$coverImage = null;
$coverImageOffset = array("x" => 0, "y" => 0);
/* If a list of tags is submitted, check for every item if the item is an article or a
* video
*/
if ($mainType == "tag") {
if ($item["TagRelationship"]["article_id"] != null) {
$newItem["Article"]["id"] = $item["TagRelationship"]["article_id"];
$newItem["Article"]["slug"] = $item["Article"]["slug"];
$newItem["Article"]["title"] = $item["Article"]["title"];
$newItem["Article"]["created"] = $item["Article"]["created"];
$newItem["User"] = $item["Article"]["User"];
$newItem["Album"]["Photo"] = $item["Article"]["Album"]["Photo"];
$item = $newItem;
$type = "article";
} elseif ($item["TagRelationship"]["video_id"] != null) {
$type = "video";
}
}
// If a list with videos is supplied, format the duration
if ($type == "video") {
// Set the coverImage
$coverImage = $this->CoverImage->getYouTubeCover($item["Video"]["youtubeId"]);
// If a video lasts shorter than an hour, only show minutes/seconds
if ($item[ucfirst($type)]["duration"] < 3600) {
$duration = gmdate("i:s", $item[ucfirst($type)]["duration"]);
}
// Otherwise show hours as well
else {
$duration = gmdate("H:i:s", $item[ucfirst($type)]["duration"]);
}
} elseif ($type == "article") {
$coverImage = $this->CoverImage->getArticleCover($item["Article"]["id"], $item["Album"]["Photo"]);
$coverImageOffset = $this->CoverImage->getArticleCoverOffset($item["Article"]["id"], $item["Album"]["Photo"]);
}
?>
<li>
<a href="/<?php print($type); ?>s/<?php print($item[ucfirst($type)]["id"]); ?>/<?php print($item[ucfirst($type)]["slug"]); ?>">
<p class="addedDate">Added:

print($this->Time->timeAgoInWords($item[ucfirst($type)]["created"], array(
'accuracy' => array('minute' => 'minute', 'hour' => 'hour', 'week' => 'week', 'day' => 'day', 'month' => 'month', 'year' => 'year'),
'end' => 'never')));
if ($type == "article") {
?>

}
?>

<ul class="itemDetails">

if ($mainType == "tag") {
?>
<p class="label"><?php print(ucfirst($type)); ?></p>
<?php
}
if ($type == "video") {
?>
<p class="duration"><?php print($duration); ?></p>
<?php
}
?>
</li>
<li>
<p><?php print($item[ucfirst($type)]["title"]); ?></p>
</li>
</ul>
</a>
</li>

</ul>
<?php
$this->end();

您很可能没有取消在最后一个元素中设置的变量,它们会在整个视图中被记住。第一次通话后尝试取消设置项目 -
$this->element('itemList', array('type' => "video", 'items' => $latestVideos));
echo $this->fetch('itemList');
unset($items);
就像评论所说的那样,如果这不起作用,我们需要看到你的元素本身来诊断问题。如果您在处理的所有内容结束时进入元素本身,请取消设置包含您正在显示的所有项目的数组。这应该可以解决问题。

经过一些研究后,我在CakePHP Cookbook中发现了以下内容:
// Clear the previous content from the sidebar block.
$this->assign('sidebar', '');
果然这就行了。
感谢你们的帮助!
