• Simplification of Kahi’s WordPress Notes

  Published: On Sunday, July 11, 2010

  This blog just got a bit simplified. A few czech articles, since being no longer relevant, were removed. No other articles in Czech are intended to be published here anymore, so both separated RSS feeds were removed – maybe you could update your RSS reader, but a redirection to a global feed is already active anyway.

  Pardon me, I do realize I am not giving this blog much effort. There are more important things to do – before any bigger site (blog) redesign, I should take care about my plugins – not all of them are really updated accordingly to current WordPress status. Before that, there are commercial things to do and as you know, writing a blog and plugins is not the easiest way to… make a living. :-)

  What else can I say than „stay tuned“? Well, it's not too bad recommendation – there are a few plugin-ideas I want to publish or implement in the following weeks and these won't be totally worthless, I'm confident to say.

  For Texy lovers, there's a good news now! New updated version of plugin will be ready soon. I have restarted improving this one year old version. The current one is downloadable from here (warning, alpha!) – but in a few days you'll be able to get updates via automatic plugin update.

• Adding number to comments (to each of them)

  Published: On Friday, April 16, 2010

  How to add a number before each comment can happen to be bigger problem than it seems. Hopefully my instructions will at least put you on the right path.

  Basic set-up

  1. Open functions.php, find the function describing a comment's template.
  2. inside the function, just at the beginning, add: static $comment_number; $comment_number ++; to accomplish incrementing of the number.
  3. somewhere inside the function body add echo $comment_number; to print the number. (Eventually including the php opening marks: < ?php echo $comment_number; ?>)

• Constants in WordPress

  Constants defaultly defined in WordPress 2.9.x. (There is 67 of them.) I can't remember the names. (So I'm sharing the cheatsheet.)

• Plugin development tip: Analyse your database queries

  Published: On Friday, September 11, 2009

  If you are an advanced plugin developer, you certainly know, you should keep number of db queries made by your plugin as small as possible. Getting the total number of database queries made when generating page is obvious: get_num_queries() returns the number.

  What is not so obvious, is how to display actual performed MySQL queries (strings) – which might be useful in various scenarios of performance optimization. WordPress is prepared for that task:

  1. step: Add into your wp-config.php file this constant/value which enables remembering of all performed queries.

  define ('SAVEQUERIES', true);

• Too many upgrades these days? Not really a problem.

  Published: On Wednesday, August 12, 2009

  Another minor WP version is out and guys in (WP)Tavern are discussing whether it's O.K. or it isn't and how they feel about it and so on. I will prefer pin my humble opinion here, so that it will seem like this site is still alive :-).

  For me, it's pretty much OK that the new version was released immediately after fixing the issue. „The problem“ of new release are the implications. Which means:

  1. „new version available“ announcement method
  2. upgrade distribution method

• Single wp-config for web and localhost

  Published: On Saturday, August 8, 2009

  Pretty usual routine is to develop site on localhost server and after some progress move it online. This transfer is complicated by three not-always-necessary steps.

  1. database settings in wp-config.php file are different
  2. settings of home- and site- URLs are different (defaultly located in wp_options table)
  3. eventually the base-path in .htaccess file is different

  First two points can be easily solved by using single wp-config. Especially is the benefit visible at the point #2, when you don't have to browse phpMyAdmin for that 2 particular rows, because these paths are written into wp-config.php file.

• Voted for media features in 2.9

  Published: On Thursday, July 9, 2009

  On topic of the recent (and today still running) survey on media handling / library / related settings and similar stuff I want to say a little word.

  I don't fully understand all of the proposed enhancements, although they were „explained“ in the announcing article as well as at beginning of the survey itself. I think it's sometimes possible to imagine various (quite different) things under each of the definitions.

  I can't say how much I a particular feature want, since each feature can be implemented in many ways and the way of implementation can influence my „desire“ for feature very much (I suppose). That makes answering even more complicated.
