How to continuously developing a WP site that is already deployed in production without damaging it during development

You’re most of the way there with your current code – you’re correct that you can wrap the condition around what you’ve already got. The is_page() function allows you to check for an array of pages, so as long as you plan to specify pages manually, all you need to do is <?php if (is_page(array(11, … Read more

After declaring woocommerce theme support products are no longer displayed

See this post for WooCommerce templating mechanism. One basic principle is: only overwrite things that you want to customize, not more. So you should remove all files that are not changed, look out for double lines of code(meaning you maybe declare the same things twice, maybe with different vars/namespace and/or something else), which might be … Read more

404 page is not the same when using PHP code in functions

template_include is a filter hook, so you are supposed to always return the full absolute filesystem path to a template, and not doing the get_template_part() and exit calls. And as for setting the 404 status, I would instead use the pre_handle_404 filter, but the wp action can also be used: (note that these examples are … Read more

Disable Typed Parameters for JavaScript in PhpStorm? [closed]

Just in case someone with the same problem faces this question; the best solution I’ve currently found is the use of the @type doc tag instead, so you would write something like: /** * @param word – Word used as the greeting * @return {void} * @type {(word : string) => void} */ function sayHiThere( … Read more
