我希望将Word Link缩短器与Wordpress一起使用。我想使用较短的链接来帮助用户在社交媒体上发布更多信息,这点很贵。谷歌提供了大量的补贴,想要使用。 API密钥可用,但需要使用php之前的Wordpress渲染页面来实现。
当前代码
<a rel="nofollow" href="http://www.facebook.com/sharer.php?u=<?php the_permalink();?>&t=<?php echo urlencode(get_the_title($id)); ?>" title="Share this post on Facebook">
<img src="<?php echo get_template_directory_uri(); ?>/images/facebook.png" border="0" alt="Facebook"/>
</a>
<a rel="nofollow" href="http://twitter.com/home?status=<?php echo urlencode("Currently reading: "); ?><?php the_permalink(); ?>" title="Share this article with your Twitter followers">
<img src="<?php echo get_template_directory_uri(); ?>/images//twitter.png" border="0" alt="Twitter"/>
</a>
<a href="https://plus.google.com/share?url=<?php the_permalink(); ?>" title="Share this on Google+">
<img src="<?php echo get_template_directory_uri(); ?>/images/google_plusone_share.png" border="0" alt="Google+"/>
</a>
总结一下,我需要一个如何在使用内置函数时强制执行Google链接缩短程序API的示例,例如:
the_permalink();
非常感谢。

你不想挂钩the_permalink
,否则使用它的每个内部页面链接都将通过谷歌路由,这显然是一个坏主意。
而是创建一个新函数来返回缩短的链接:
//wrapper function to echo the result, consistent with Wordpress the_* and get_the_* style
function the_google_short_link(){
echo get_the_google_short_link();
}
function get_the_google_short_link(){
// Google::shortlink is an example, replace with whatever code you have that creates the shortlink
return Google::shortLink(get_permalink(get_the_ID()));
}
然后在您的模板中使用是必需的:
<a rel="nofollow" href="http://www.facebook.com/sharer.php?u=<?php the_google_short_link();?>&t=<?php echo urlencode(get_the_title($id)); ?>" title="Share this post on Facebook">
<img src="<?php echo get_template_directory_uri(); ?>/images/facebook.png" border="0" alt="Facebook"/>
</a>

您需要使用add_filter('the_permalink','your_custom_function');
来自定义永久链接的输出。
your_custom_function
的粗略轮廓:
function your_custom_function($url){
// Get your token (if you use OAuth)
// Send your long url with the [HTTP API][1]
// return the short url you got.
}

使用此课程与google api和goo.gl缩短服务进行对话:

这是一个返回goo.gl链接的简短函数
function GetShortURL( $url ){
global $post;
$appid = '1234567...'; // your app id
$shorturl = new mashsuGoogl($appid);
$shorturlres = $shorturl->shorten($url, false);
// Shorten URL
return $shorturlres;
unset($googl);
}
