谷歌链接缩短与自定义社交媒体图标

Question

I am looking to use Google Link shortener with Wordpress. I want to use shorter links to help users post more in social media, bitly is far to expensive. Google gives a massive allowance, which want to use. API key is available but need to implement using php prior Wordpress rendering the page.

Current Code

<a rel="nofollow" href="http://www.facebook.com/sharer.php?u=<?php the_permalink();?>&amp;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>

To summarise I need a example of how to enforce Google link shortener API while using the in built functions such as:

the_permalink();

Many thanks.

You dont want to hook into the_permalink, else every internal page link that uses it will be routed via google, which is obviously a bad idea.

Instead create a new function to return the shortened link:

//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())); 
}

then use in your templates are required:

<a rel="nofollow" href="http://www.facebook.com/sharer.php?u=<?php the_google_short_link();?>&amp;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"/>
