如何在Wordpress中添加到摘录的额外链接

Question

I'm trying to get this link to look like this:

Comment on this show >> | Listen to this show >>

Where "Comment on this show >>" gets populated properly with its permalink.

"Listen to this show >>" link should be populated with that posts 'Listen Now' custom field value.

function holylandmoments_comment_link() {
return ' <a class="read-more-link" href="'. get_permalink() . '">' . __( 'Comment on this show &raquo;', 'holylandmoments-show' ) . '</a> &nbsp;|&nbsp; <a class="read-more-link" href="'. get_post_meta($post->ID, 'Audio File',true); . '">' . __( 'Listen to this episode &raquo;', 'holylandmoments' ) . '</a>';
}

Problem is I don't get the path to the custom field value of Listen Now to populate the second link... any ideas??

The custom field value is a link to an audio file. So for all posts that fall under the category shows there is a custom field named 'Audio File' the value of that field is:

http://www.mydomain.org/audio/sample.mp3

So when the excerpt is called for archive pages to display I need two links to display one that points back to the post and another that points to the MP3 file.

So in my functions.php file I have the function above and then I call it with:

function holylandmoments_custom_excerpt_more( $output ) {
if ( has_excerpt() && in_category( _x('devotionals', 'devotionals category slug', 'holylandmoments') ) &&! is_attachment() ) {
    $output .= holylandmoments_read_more_link();
}
else
if ( has_excerpt() && in_category( _x('shows', 'shows category slug', 'holylandmoments') ) &&! is_attachment() ) {
    $output .= holylandmoments_comment_link();
}
return $output;
}
add_filter( 'get_the_excerpt', 'holylandmoments_custom_excerpt_more' );

Thanks!

Answer 1

You have an extra semicolon in there.

href="'. get_post_meta($post->ID, 'Listen Now',true); . '">'
                                                    ^

Change to:

href="'. get_post_meta($post->ID, 'Listen Now',true) . '">'

The $post variable may not be in the current scope, so try bringing in the global $post into it.

function holylandmoments_comment_link() {
   global $post;
   return ' <a class="read-more-link" href="'. get_permalink() . '">' . __( 'Comment on this show &raquo;', 'holylandmoments-show' ) . '</a> &nbsp;|&nbsp; <a class="read-more-link" href="'. get_post_meta($post->ID, 'Audio File',true); . '">' . __( 'Listen to this episode &raquo;', 'holylandmoments' ) . '</a>';
}

I believe the function the_ID() also returns the ID of the current post, so try the following if it the other one doesn't work:

function holylandmoments_comment_link() {
   return ' <a class="read-more-link" href="'. get_permalink() . '">' . __( 'Comment on this show &raquo;', 'holylandmoments-show' ) . '</a> &nbsp;|&nbsp; <a class="read-more-link" href="'. get_post_meta(the_ID(), 'Audio File',true); . '">' . __( 'Listen to this episode &raquo;', 'holylandmoments' ) . '</a>';
}
