I needed a placeholder for tags input but it’s boring to display the same tags every time. But unlike posts, WP doesnt have “rand” orderby paramater. So what you can do; is to get a #no of tags and shuffle them.<\/p>\n

\"tagdUntitled-6\"<\/a><\/p>\n

So basically what we do is:<\/p>\n

    \n
  1. Check if we have a recent transient<\/li>\n
  2. If not, query the tags.<\/li>\n
  3. Note the allowed orderby parameters for tags are defined as $tag_rnd_arr, which will add more randomness to them<\/li>\n
  4. 11 is the number of tags to get, 3 is the number of tags to return. You can increase or decrease them<\/li>\n<\/ol>\n
    function eobtn_get_rand_tags() {\r\n\t$rand_tags = get_transient(\"rand_tags\");\r\n\t\/\/ Check if we have queried 3 random tags recently\r\n\tif(!$rand_tags) {\r\n\t\t$tag_rnd_arr = array(\"name\",\"count\",\"term_id\");\r\n\t\t$tag_argz=array(\r\n\t\t\"orderby\" => array_rand($tag_rnd_arr),\r\n\t\t\"order\" => \"DESC\",\r\n\t\t\"number\" => 11,\r\n\t\t\"hierarchical\" => false,\r\n\t\t\"fields\" => \"names\"\r\n\t\t);\r\n\t\t$tags = get_tags($tag_argz);\r\n\t\t$rand_tags = array();\r\n\t\tshuffle($tags);\r\n\t\t$ran_key_arr = array_rand($tags, 3);\r\n\t\tforeach ($ran_key_arr as $ran_tag ) {\r\n\t\t\t$rand_tags[] = $tags[$ran_tag];\r\n\t\t}\r\n\t\t\/\/ Save the result for a short time (3 secs) to save an extra query hit if you have thousands of tags and \/ or visitors\r\n\t\tset_transient(\"rand_tags\",$rand_tags, 3);\r\n\t}\r\n\treturn $rand_tags;\r\n}<\/pre>\n
    If you need echoing them instead of returning, you can simply echo them using<\/p>\n
    \tif ($rand_tags) {\r\n\t  foreach($rand_tags as $tag) {\r\n\t\t  echo '<a href=\"'.get_tag_link($tag->term_id).'\">'.$tag->name . '<\/a>';\r\n\t\t  if($tc != 3 || $ttc != 1)  echo ', ';\r\n\t  }\r\n\t}<\/pre>\n
