wordpress给文章加内链或外链短代码

在wordpress文章编辑框内,文本模式下,出现2个段代码框,根据自己的需求使用代码吧,将代码插入到 主题目录的 functions.php 内即可!

//给文章加内链短代码
function git_insert_posts($atts, $content = null)
{
extract(shortcode_atts(array('ids' => ''), $atts));
global $post;
$content = '';
$postids = explode(',', $ids);
$inset_posts = get_posts(array('post__in' => $postids));
foreach ($inset_posts as $key => $post) {
setup_postdata($post);
$content .= '<div class="neilian"><div class="fll"><a target="_blank" href="' . get_permalink() . '" class="fll linkss"><i class="fa fa-link fa-fw"></i> ';
$content .= get_the_title();
$content .= '</a><p class="note">';
$content .= get_the_excerpt();
$content .= '</p></div><div class="frr"><a target="_blank" href="' . get_permalink() . '"><img src=';
$content .= link_the_thumbnail_src();
$content .= ' class="neilian-thumb"></a></div></div>';
}
wp_reset_postdata();
return $content;
}
add_shortcode('neilian', 'git_insert_posts');
//给文章加外链短代码
function git_external_posts($atts, $content = null)
{
extract(shortcode_atts(array('img' => '0'), $atts));
$ch = curl_init( $content );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($ch);
curl_close($ch);
$title = preg_match('!<title>(.*?)</title>!i', $result, $matches) ? $matches[1] : '因为某些不可控制原因,标题已丢失,请勿想念';
$tags = get_meta_tags( $content );
$description = $tags['description'];
if( $img ==0){
$imgpath = get_template_directory_uri() . '/assets/img/pic/' . mt_rand(1, 12) . '.jpg';}if( $img ==1){
$imgpath = '//image.thum.io/get/width/160/' . $content . '';}
global $post;
$contents = '';
setup_postdata($post);
$contents .= '<div class="neilian wailian"><div class="fll"><a target="_blank" href="' . $content . '" class="fll linkss"><i class="fa fa-link fa-fw"></i> ';
$contents .= $title;
$contents .= '</a><p class="note">';
$contents .= $description;
$contents .= '</p></div><div class="frr"><a target="_blank" href="' . $content . '"><img src=';
$contents .= $imgpath;
$contents .= ' class="neilian-thumb"></a></div></div>';
wp_reset_postdata();
return $contents;
}if ( function_exists('curl_init') ) {
add_shortcode('wailian', 'git_external_posts');
}
