How to use title attributes in sidebar widget?

Question

I have a custom post type "article" & I need to display some custom urls is a widget in the sidebar using php code widget. When I use this code withing the loop it works perfectly:

<a href="<?php echo site_url('/article/full-text/'); ?>
<?php $slug = $post->post_name; echo $slug; ?>" title="<?php the_title_attribute(); ?>">Full Text</a>

but when I put this code in the php code widget it displays only the first part of the url. To be more clear, when I use this code within the loop the url will be (www.my-site.com/article/full-text/article-title). But in the php code widget the url will be (www.my-site.com/article/full-text/). Am I missing something here? Any help please?

Answer 1

You'r missing $post variable ( it is not defined and that for you don't get post_name ).

As a solution you could add global $post;

You'r code would be like:

<a href="<?php echo site_url('/article/full-text/'); global $post;
$slug = $post->post_name; echo $slug; ?>" title="<?php the_title_attribute(); ?>">Full Text</a>
