那些年，我們一起追的女孩。

其實係上年就已經睇完這本書，這亦是我看的第一部九把刀作品。係全城都對電影版瘋狂的時候，我還是比較想看看原著。

好熱血的一本書，一拿上手就不願放下，所以兩天就看完了。回想自己的青春，好像從沒做過一件熱血的事，最最最熱血應該是大學時的五人足球反敗為勝打進四強，哈哈。除了熱血，不得不提的是柯景騰的堅持，對夢想的執著，真真正正做到了一個很厲害的人…

Drupal – Get taxonomy term by term ID

ykyuen — Mon, 23 Jan 2012 04:00:40 +0000

In Drupal 6, you can get the term object using the following function

taxonomy_get_term($tid);

In Druapl 7, this function is deprecated but you can get the term by term name.

taxonomy_get_term_by_name($name);

If you want to get the term by term ID, there is not yet a official solution but hopefully you could find more information in the following discussions.

ykyuen — Fri, 20 Jan 2012 04:00:39 +0000

About 2 months ago i published a post on how to get the number of nodes of a specific taxonomy term by term ID.
Drupal – Get number of nodes of Taxonomy Term by Term ID

Unfortunately, the taxonomy_term_count_nodes() no longer works in Drupal 7 but you can get the count by Views in D7.

1. Create a term view (A vocabulary called XXX is used in this example)

2. Add a new relationship Taxonomy term: Content using XXX

3. Turn on the Use aggregation under OTHER settings

4. Add Content: Nid as new field and set the Aggregation type to Count

Done =)

PHP – Convert URL into clickable link by Regular Expression

ykyuen — Wed, 18 Jan 2012 04:00:27 +0000

I want to convert the all URLs in a string into clickable links. I found a solution in StackOverflow but probably it only works in PHP 5.2 since it uses eregi_replace() which is deprecated in PHP 5.3. So use it with cares.

\\1', $text);
    $text = eregi_replace('(((f|ht){1}tps://)[-a-zA-Z0-9@:%_\+.~#?&//=]+)',
            '\\1', $text);
    $text = eregi_replace('([[:space:]()[{}])(www.[-a-zA-Z0-9@:%_\+.~#?&//=]+)',
    '\\1\\2', $text);
    $text = eregi_replace('([_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3})',
    '\\1', $text);
    return $text;
  }
?>

Done =)
