WP-CLI on Gentoo

I recently encountered this error when running wp search-replace:

PHP Fatal error:  Call to undefined function cliline() in …/wp-cli/vendor/wp-cli/php-cli-tools/lib/cli/Table.php on line 107

The FAQ says that you will need to install the php-process package, but there’s no such package nor USE flag in Gentoo. After some digging, I found out that the sysvipc and sharedmem are the USE flags that need to be added.

KMail vs. KPPP

If you’re using a dial-up connection via KPPP and KMail’s complaining about network connection not being detected, just fire up Akonadi Console and toggle your resources’ states from there. I’ve yet to find the solution for this but this trick should help you get your new mails.

Add HTML Tags in Post and Widget Titles

In a recent project, I needed to use <span /> tags to add some styles (just color, actually) to post and widget titles. By default — and there’s no hook to disable this — WordPress strips any HTML tags found in post and widget titles. Here’s my solution to this problem. Please keep in mind that I only needed to add <span /> tags, so if you need to add more tags, you should modify the code to fit your needs :) Continue reading Add HTML Tags in Post and Widget Titles

wp_list_pages() for Custom Post Types

wp_list_pages() is a handy little function for displaying a list of hierarchical post type, and it works with custom post types too. Unfortunately, when used for a custom post type, the list items don’t have the necessary CSS classes for current page item/ancestors. Here’s a quick fix for this particular problem.

function kct_page_css_class( $css_class, $page, $depth, $args ) {
  if ( empty($args['post_type']) || !is_singular($args['post_type']) )
    return $css_class;

  $_current_page = get_queried_object();

  if ( in_array( $page->ID, $_current_page->ancestors ) )
    $css_class[] = 'current_page_ancestor';
  if ( $page->ID == $_current_page->ID )
    $css_class[] = 'current_page_item';
  elseif ( $_current_page && $page->ID == $_current_page->post_parent )
    $css_class[] = 'current_page_parent';

  return $css_class;
}
add_filter( 'page_css_class', 'kct_page_css_class', 10, 4 );

Using Built-in Post Finder in Plugins

I was making some improvements to the KC Posts widget module in my KC Essentials plugin, and I wanted to make it easy for the users to find post IDs they want to include/exclude from the query. As you may already know, in the Media admin page, we can ‘attach’ an attachment to a post. It uses a neat jQuery UI dialog box to find posts. Here’s how I use it in KC Essentials.

jQuery in Widgets Admin Page

Here’s a quick tip. If you built a custom widget for your themes/plugins and you need jQuery for the configuration form, you’ll need to call it when the ajax process is done, that is when a widget was just dropped to a sidebar/widget area, or the user just saved the configuration.

jQuery(document).ready(function($) {
  $('.widgets-sortables').ajaxSuccess(function() {
    // do your thing
  });
});
