WordPress文章格式中有一种是链接，用来快速分享一个链接，如果我们可以将文章的这个链接自动链接到这篇文章的标题中，远比在文章内容中直接显示这个链接来的完美。将下面的代码添加到当前主题的 functions.php 中：
function get_content_link( $content = false, $echo = false )
{
if ( $content === false )
$content = get_the_content();
$content = preg_match_all( '/hrefs*=s*["']([^"']+)/', $content, $links );
$content = $links[1][0];
if ( empty($content) ) {
$content = false;
}
return $content;
} |
function get_content_link( $content = false, $echo = false )
{
if ( $content === false )
$content = get_the_content();
$content = preg_match_all( '/hrefs*=s*["']([^"']+)/', $content, $links );
$content = $links[1][0];
if ( empty($content) ) {
$content = false;
}
return $content;
}
然后你可以类似下面的代码来为标题添加这个链接：
<h2><a href="<?php echo get_content_link( get_the_content() ); ?>"><?php the_title(); ?></a></h2>
<p><?php the_excerpt(); ?></p>
<a href="<?php the_permalink(); ?>">Comment »</a> |
<h2><a href="<?php echo get_content_link( get_the_content() ); ?>"><?php the_title(); ?></a></h2>
<p><?php the_excerpt(); ?></p>
<a href="<?php the_permalink(); ?>">Comment »</a>
