Wordpress get_permalink（）PHP链接不适用于帖子中的外部链接

Question

Using wordpress and editing some PHP code in my child theme and have run into an issue with a sidebar widget for popular posts.

Each blog post in wordpress that is popular accurately shows up in the popular posts sidebar, and clicking the story title it will go to the single story page on my blog .

The correct code in this widget to link to my own blog posts in widgets.php is:

    if ( $popular_posts->have_posts() ) {
        $result .= '<div class="post-popular"><ul class="list">';
        while ( $popular_posts->have_posts() ) {
            $popular_posts->the_post();
            $comments_text = sprintf( _n( '%1$s comment', '%1$s comments', get_comments_number(), APP_TD ), get_comments_number() );
            $result .= '<li><a href="' . get_permalink() . '">' . get_the_title() . '</a> - ' . $comments_text . '</li>';
        }
        $result .= '</ul></div>';
    }

Since this is a sidebar widget of popular articles, I would like the sidebar clicks to go directly to the external site for each article, and not my blog posts.

Within each blog post is a direct external link to the actual article for each. This is tagged for each post as the following code article_out_url

I tried the following code edit for get_permalink() to make it get_permalink($url) to go to each external such such as:

$url = get_post_meta( $post->ID, 'article_out_url', true );
$result .= '<li><a href="' . get_permalink($url) . '">' . get_the_title() . '</a> - ' . $comments_text . '</li>';

Such as the following:

    if ( $popular_posts->have_posts() ) {
        $result .= '<div class="post-popular"><ul class="list">';
        while ( $popular_posts->have_posts() ) {
            $url = get_post_meta( $post->ID, 'article_out_url', true );
            $popular_posts->the_post();
            $comments_text = sprintf( _n( '%1$s comment', '%1$s comments', get_comments_number(), APP_TD ), get_comments_number() );
            $result .= '<li><a href="' . get_permalink($url) . '">' . get_the_title() . '</a> - ' . $comments_text . '</li>';
        }
        $result .= '</ul></div>';
    }

However, this didn't work. Instead of going to the external link, clicking on the link simply went to my root domain only. Not even the individual post on the topic.

I'm stumped. Any ideas with how I can get each article link to go to the the article_out_url URL for each post? Thanks.

Answer 1

read http://codex.wordpress.org/Function_Reference/get_permalink

inside loop it's the current post. outside loop you need a post id.

but it's a post on your blog.

i think the solution is easier than you imagine. grab the url, and stick it in the href. you may want to trim it. (post meta is a bit junk in junk out.)

get_permalink（）仅适用于WordPress帖子和页面，而不适用于外部链接。
