在Joomla类别博客覆盖中添加此项.链接到相应的文章


AddThis in Joomla Category Blog Override. Linking to corresponding articles

我已经覆盖了"blog.php";,分类博客将AddThis社交媒体共享插件放在每篇文章的底部。在joomla 3.0 上工作

Category博客布局每页显示许多文章。默认情况下,AddThis使用您当前的页面来分享/点赞/推特等。

我添加的这个代码看起来像这样:

<div class="article-sharing">
    <!-- AddThis Button BEGIN -->
    <div class="addthis_toolbox addthis_default_style">
        <a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
        <a class="addthis_button_tweet"></a>
        <a class="addthis_counter addthis_pill_style"></a>
    </div>
    <script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid=undefined"></script>
    <!-- AddThis Button END -->
</div>

我当然想要的是将正在使用的URL更改为相应的文章。这是可能的(http://support.addthis.com/customer/portal/articles/381242-url-title#.Ucd1HevmT2x)。

代码应该是这样的(只有动态url):

<div class="article-sharing">
    <!-- AddThis Button BEGIN -->
    <div class="addthis_toolbox addthis_default_style"
        addthis:url="http://example.com/blog/my-article-about-horses"
        addthis:title="The title of my article"
        addthis:description="The short article description">
        <a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
        <a class="addthis_button_tweet"></a>
        <a class="addthis_counter addthis_pill_style"></a>
    </div>
    <script type="text/javascript" src="//s7.addthis.com/js/300/addthis_widget.js#pubid=undefined"></script>
    <!-- AddThis Button END -->
</div>

如果有人能帮助我更好地理解我是如何做到这一点的,那就太好了。

addthis:url="http://example.com/blog/my-article-about-horses"
addthis:title="The title of my article"
addthis:description="The short article description"

更新

谢谢Ahmad的回答。这帮了我很多忙。

这是我当前在blog_item.php文件中的AddThis代码。它适用于推特、电子邮件等。但当涉及到脸书时,我有一些问题。";addthis:标题"和描述没有被使用。相反,我在index.php文件中的OG标签正在被使用。当在Facebook上点击共享链接时,它仍然链接到正确的文章。这可能会让用户有点困惑——当他/她收到Facebook共享弹出窗口时,他/她想分享的文章没有任何内容——只有关于页面的一般信息。

<div class="article-sharing">
    <!-- AddThis Button BEGIN -->
    <div class="addthis_toolbox addthis_default_style"
    addthis:url="http://www.tolt-inspiration.com<?php echo JRoute::_(ContentHelperRoute::getArticleRoute($this->item->slug, $this->item->catid)); ?>"
    addthis:title="<?php echo $this->escape($this->item->title); ?>"
    addthis:description="<?php echo $this->escape($this->item->metadesc); ?>">
    <a class="addthis_button_facebook_like" fb:like:layout="button_count"
    addthis:title="<?php echo $this->escape($this->item->title); ?>"
    addthis:description="<?php echo $this->escape($this->item->metadesc); ?>"></a>
    <a class="addthis_button_tweet"></a>
    <a class="addthis_counter addthis_pill_style"></a>
</div>
<!-- AddThis Button END -->
</div>

如何解决?

关于编辑核心文件的注意事项

首先让我们澄清一下,编辑Joomla的核心文件是一种糟糕的做法。您应该始终使用覆盖。这样你就可以确保当Joomla更新时,你的更改不会被覆盖

更新:没有注意到问题标题说OP已经在处理覆盖。

Joomla类别视图的渲染方式

让我们剖析一下Joomla中的类别视图(按执行顺序)。它以default.php(所有视图之母)开始,然后加载:

  1. blog.php(用于博客视图;显然)这部分输出类别描述、图像、标题、列。。。等等,并将调用以下部分:
    1. blog_item.php--显示文章<-这是您应该处理的文件。
    2. blog_links.php
  2. default_items.php(用于列表视图

对于<span class="article_separator">&nbsp;</span>之前的Joomla 1.5,添加代码

对于<div class="item-separator"></div>之前的Joomla 2.5,添加代码

代码

<div class="article-sharing">
   <!-- AddThis Button BEGIN -->
   <div class="addthis_toolbox addthis_default_style"
   addthis:url="<?php echo $this->item->readmore_link; ?>"
   addthis:title="<?php echo $this->escape($this->item->title); ?>"
   addthis:description="<?php echo $this->escape($this->item->metadesc); ?>">
   <a class="addthis_button_facebook_like" fb:like:layout="button_count"></a>
   <a class="addthis_button_tweet"></a>
   <a class="addthis_counter addthis_pill_style"></a>
</div>

添加<script>

注意,现在我们还没有添加addthis <script>。您不希望将其添加到blog_item.php,否则它将被多次添加。我们将把它添加到blog.php中。使用Joomla的API添加:

紧随其后:

defined('_JEXEC') or die('Restricted access');

添加:

$doc =& JFactory::getDocument();
$doc->addScript("//s7.addthis.com/js/300/addthis_widget.js#pubid=undefined");

注意

使用addScript方法添加脚本不是必需的,但它比简单地在模板中添加脚本要好。例如,一些插件会在关闭body标签之前移动每个脚本标签;它提供了一种抓住那个物体的方法。
