It seems your code is OK and won’t break anything but for it to work properly across different pages, maybe you should use Transient API functions instead of Object Cache counterparts. Why? Object Cache is not persistent by default (i.e. does not work across different pages). It will persist only if install an persistent cache … Read more
You’re absolutely right in your assumption. CSS should never be tied to post IDs, because they can always change (for example if you decide to migrate your posts to another install). You can always shift control towards the admin dashboard. Add a custom field in a post/page that you want styled in a special way … Read more
I was having the same problem and this is how I solved it: First, the generated JSON file has some errors. You need to update where it says messages with your text domain. There are three places where that needs to be changed. I also had to change the lang attribute to be all lowercase … Read more
What’s the plugin? Is it using custom translations in mo/po files? Is there an admin interface which allows you to set the plugin locale? There is a generic filter which you might be able to add to the plugin code to set the language which might look something like the following (obviously set the language … Read more
Before we go into details, it should be noted that the guides you are referring to is only what it is, a guide. Just like coding standards (which not even the core developers stick to 🙂), the WordPress Handbook is just a guide to developers, it is not the alpha and omega. The basic idea … Read more
I’m not really up to date on WPML and how it handles translations, but my general understanding is that in most cases it simply creates duplicate entries for each language and links them together with the “original”. However, I recently hade a similar problem where I needed the ability to add a “pluralized” version of … Read more
esc_html_e() and esc_attr_e() are merely wrapper functions for _ to save a little bit of typing and help with readability. You’re right, there isn’t one for _n, so you’ll just need to do the “wrapping” yourself: printf( esc_attr( _n( ‘%s item’, ‘%s items’, $count, ‘textdomain’ ) ), number_format_i18n( $count ) );
The gettext filter can be used to change strings that use the gettext functions. add_filter( ‘gettext’, ‘wpse_change_error_string’, 10, 3 ); /** * Translate text. * * @param string $translation Translated text. * @param string $text Text to translate. * @param string $domain Text domain. Unique identifier for retrieving translated strings. * * @return string */ … Read more
Regardless if you go the PHP or jQuery route, I suggest you set up your filters or enqueue your Javascript in the admin_head-post[-new].php or admin_print_scripts-post[-new].php hook. There you can be sure that the global variable $post_type is set, and can check whether it is slide. Since the post thumbnail code is called after these hooks, … Read more
You should move the po- and mo-file with the translation of your plugin outside your plugin’s directory. Whenever you update your plugin, your plugin files are replaced causing any file that is not part of the default plugin package to be deleted. (If you are translating your own plugin, you could as well add the … Read more
