我刚刚按照Red Velvet Cookbook上的标签教程（https://book.cakephp.org/3.0/en/tutorials-and-examples/cms/tags-and-users.html）进行操作。我成功地在网站上添加了标签。虽然我觉得它还需要几件事。用逗号分隔的标签列表就是列表。我希望有一个链接列表。这些链接显然将链接到使用相同标签标记的帖子列表。由于本教程，该列表已经存在。网址看起来像http：// localhost：8765 / story / tagged / cats /
我已经摆弄了HTML助手来尝试创建链接，但是我不确定如何使用数组来做到这一点。任何线索或帮助将不胜感激。
这是我模板中显示标签列表的行
<p><b>Tags:</b> <?= h($story->tag_string) ?></p>
这是获取tag_string的函数
class Story extends Entity
{
/**
* Fields that can be mass assigned using newEntity() or patchEntity().
*
* Note that when '*' is set to true, this allows all unspecified fields to
* be mass assigned. For security purposes, it is advised to set '*' to false
* (or remove it), and explicitly make individual fields accessible as needed.
*
* @var array
*/
protected $_accessible = [
'*' => false,
'tag_string' => true
];
protected function _getTagString()
{
if (isset($this->_properties['tag_string'])) {
return $this->_properties['tag_string'];
}
if (empty($this->tags)) {
return '';
}
$tags = new Collection($this->tags);
$str = $tags->reduce(function ($string, $tag) {
return $string . $tag->name . ', ';
}, '');
return trim($str, ', ');
}
}
在您的$story实体中，您具有tags已在计算字段中使用的属性tag_string。要获得分离的标签，您需要在模板中对其进行迭代，例如：
<ul>
<?php foreach($story->tags as $tag): ?>
<li><?= $tag->title ?></li>
<?php endforeach; ?>
</ul>
假设您的StoriesControllernamed中有一个方法tagged，该方法接受一个参数：标记标题，则可HtmlHelper以为每个标记构建链接：
<ul>
<?php foreach($story->tags as $tag): ?>
<li>
<?= $this->Html->link($tag->title, [
"controller" => "Stories",
"action" => "tagged",
$tag->title
], [
"class" => "your-tag-link-class" //second array is for properties, in case you would like to add eg class for these links to style them using css.
]) ?>
</li>
<?php endforeach; ?>
</ul>
