I see a couple of problems here. This line if (!is_admin() || ‘default’ != $domain) return $translated; returns the Howdy right back unchanged if is_admin is false – which it is if you’re not in the dashboard. Also, you’re running your filter callback on gettext. This means it will be run every time some internationalized … Read more
In the WordPress back-end you have to use checked=”checked” (stricter XHTML), because the CSS will not be applied otherwise: <input type=”radio” name=”colors” id=”blue” checked=”checked”> this is the CSS that applies the blue dot: WordPress already provides a function for this checked() <input type=”radio” name=”colors” id=”blue” <?php checked( ‘red’, get_option( ‘color’ ) ); ?> /> so … Read more
The is_page_template() function is the incorrect function to use in this case as it checks against Page Templates and single.php is just a normal template, not a page specific one, usually meant for posts. The function you’re probably looking to use instead is is_single( $optional_posttype ) which will look for singular view of a post … Read more
You’ll need to declare support for WooCommerce in your themes functions.php file: function mytheme_add_woocommerce_support() { add_theme_support( ‘woocommerce’ ); } add_action( ‘after_setup_theme’, ‘mytheme_add_woocommerce_support’ ); Hope this helps!
Your function needs 2 arguments, but you didn’t mention this to add_action add_action( string $tag, callable $function_to_add, int $priority = 10, int $accepted_args = 1 ) https://developer.wordpress.org/reference/functions/add_action/ By only passing the tag and function to add, PHP used the defaults for priority and accepted arguments, which were a priority of 10, and 1 accepted argument. … Read more
I still say this is a jQuery issue; however, it is important to note that WordPress requires no-conflict mode for jQuery. From Codex: jQuery noConflict Wrappers The jQuery library included with WordPress is set to the noConflict() mode (see wp-includes/js/jquery/jquery.js). This is to prevent compatibility problems with other JavaScript libraries that WordPress can link. In … Read more
There were several errors in your code. The biggest was that the function didn’t even have a closing bracket, but we can probably assume that was just not copied into your post, otherwise nothing would have been working for you. This is a filter on the content right? It looks like you want to append … Read more
I would recommend a Parent/Child theme for this. Read the section linked below for a good example of making functions within your theme pluggable. http://codex.wordpress.org/Child_Themes#Using_functions.php
I dug through the wordpress code to see what was happening when I submitted the form from the admin UI to see what function it was calling (and did a var_export() on the variable being passed in) and saw it was calling set_theme_mod( ‘nav_menu_locations’, $menu_locations );. I’ve updated my code to use this and it … Read more
You can use the get_template_part_{$slug} hook, which fires before a template part is loaded. You can find the reference here, which I find more useful than the official reference. So, I tested it in the twentytwentyone theme (yes I modified the theme directly but only for testing). I tested it with the template-parts/content/content-single.php part, and … Read more
