According to my motto:
‘Knowledge is Knowing where it is Written’
by Albert Einstein
– I like to look up the core files of WordPress where the functions are defined.
What I quite often do when I come across something new or not fully understood – a function, or template tag, or whatever wordpress related:
I search the web for it; not just with any keywords, but quite focussed.
Lets take the example of one of my earlier posts (Front Page Comments on your WordPress Blog) where I was investigating why comments don’t easily show on the front page or on archive pages of a blog:
The function in the template files that would show comments and the comment form, is ‘comments_template()’ – I therefore search for:
‘function comments_template()’
the search engine of my choice returns (apart from many other links) first of all the link to the documentation in the codex; and a link to the core file (and the exact line):
Obviously, my search engine knows me, so the relevant results show quite at the top of all possible search results; you may need to scroll down a few pages to find the important link: the one beginning with ‘PHPXRef’.
the link to follow is:
http://phpxref.ftwr.co.uk/wordpress/_functions/comments_template.html
in the page that opens, you’ll get the line:
defined at: followed by a link.
click on that link;
http://phpxref.ftwr.co.uk/wordpress/wp-includes/comment-template.php.html#comments_template
that leads you to:
with a list of some functions; click on the title of the one you are looking up.
http://phpxref.ftwr.co.uk/wordpress/wp-includes/comment-template.php.source.html#l822
in there in line 851, you have it (the code that explains why comments do not automatically show on the front page; and what you can do to make them show):
851 if ( !(is_single() || is_page() || $withcomments) || empty($post) )
btw:
This search method is also great for finding related functions, global wordpress variables, and expanding your vocabulary and understanding of wordpress terms…
Well done. I i never thought I would personally accept as true with this opinion, but I???m commencing to view things at a different view. I must research more about this simply because it seems fascinating. Another thing I don???t understand though is the way things are all related together.
