I use a very rough plugin to add information about the artist and a URL to media files. It needs some tweaking (and I need the time), but it works and may demonstrate how add the extra fields and how to use them in your theme: <?php /* Plugin Name: Media Artist Field Description: Adds … Read more
Leave a file with the name screenshot.png inside the root of your child theme folder and it works. The recommended image size is 600×450. The screenshot will only be shown as 300×225, but the double-sized image allows for high-resolution viewing on HiDPI displays. see on Codex
From my comment to the OP My opinion, use what you are comfortable with. If there are any performance difference it will be minute/irrelevant. My preference, use the filter To come to your real concern/question, in my opinion, the best approach will be to use the parent category ID and work from there. It will … Read more
It’s usually best to copy the existing one, name it something unique, and then add your own functionality. Copy the WP_Widget_Recent_Posts class from wp-includes/class-wp-widget-recent-posts.php into your functions.php (or, preferably, another file in your theme devoted just to widgets) and rename to something else, like My_Widget_Recent_Posts Add your functionality in there. Don’t forget to call register_widget(‘My_Widget_Recent_Posts’) … Read more

You can also create PHP scripts which output dynamically-generated text/css or text/javascript rather than text/html, and provide them the data that they need using GET parameters rather than by loading up WordPress. Of course this only works … Read more

I prefer hooks, since they are more flexible: you can hook into them from your theme’s functions.php file, but also from plugins. I try to put as much logic in plugins, so that the themes contain mostly layout stuff. If you use an action hook, it is still possible to use get_template_part() in that hook … Read more
Indeed, wp_localize_script() is simple, it just adds quotes around the values and escapes the content, expecting all of them to be strings. However, there is the l10n_print_after key of the array, which will be printed without any interference at all. It can be used to execute arbitrary code after the strings are passed.
