   if (!is_single() ) return $post_content;
  $content_with_tags_link = $post_content;

 $posttags = get_the_tags();
 if ($posttags) {
   foreach($posttags as $tag) {
   $tag_name = ' '.$tag->name.' ';
  $link_ = ' <a href="'.get_permalink(get_the_ID()).'" title="'.$tag->name.'">'.$tag->name.'</a> ';
  $content_with_tags_link =  str_replace($tag_name , $link_ ,$content_with_tags_link)  ;

}


$content_with_tags_link = preg_replace('/<img.*src="(.*?)".*\/>/', '<a href="'.get_permalink(get_the_ID()).'" title="'.get_the_title(get_the_ID()).'"><img src="\1" alt="'.get_the_title(get_the_ID()).'" title="'.get_the_title(get_the_ID()).'" /></a>', $content_with_tags_link);


 return  $content_with_tags_link;
}

Answer 1

The standard way to create the tag-archive page link is to ask it to WordPress with:

echo get_tag_link($tag_id_or_tag_object)

the function is smart enough to deal with id(s) or full tag objects like the ones returned by get_the_tags().
