wp_link_pages depends on four globals— $page, $numpages, $multipage, and $more. I cannot test this right now, but if I remember correctly $page is the current page and $numpages is the total number of pages. All you should need is: global $page; echo $page;
The admin stylesheets combines rules for everything: tool bar, left menu, footer and some common elements like tables and forms. You cannot disable just a part of it. If you want to apply your own rules, use a higher specificity in your CSS rules. Normally, all plugin pages use the same wrapper element: <div class=”wrap”> … Read more
There is no built in “user code” mechanism is WordPress. Your options for running your code are the theme’s functions.php file, a plugin, or a mu-plugin. You are aware of the first two options, the first of which you reasonably want to avoid. Writing a simple plugin is pretty trivial so I would not be … Read more
Thanks to Stanislav Khromov (also active on WPSE!), I learned any Callable referenced in add_shortcode() must be fully qualified, even if it is defined in the same file you’re referencing it. <?php /** * theme’s functions.php */ namespace MyNamespace; //[foobar] function foobar_func( $atts ){ return “foo and bar”; } add_shortcode( ‘foobar’, ‘\MyNamespace\foobar_func’ ); You may … Read more
I suspect the Taxonomies Codex entry is simply out of date. Per source, there are no ‘sort’ or ‘orderby’ args for register_taxonomy(). Given the purpose of the register_taxonomy() function, it doesn’t even really make sense for this function to include sort/orderby parameters. Such parameters would be relevant to listing taxonomy terms, not to registering the … Read more
Using wp_enqueue_* ‘in the body of the page’ (by which I really mean inside widget or shortocde callbacks) is an excellent way to ensure that scripts/styles are only loaded when they are needed (i.e. when the shortcode/widget is actually present on the page). Script/Styles Location Scripts and styles are then loaded either in the header … Read more
If your code, be it a theme or a plugin, does not support translation, then don’t use the translation functions. And if you don’t use these functions, you cannot use a text domain. 🙂 There is a very common error that looks like this: echo __( ‘Portfolio’ ); Portfolio is not part of WordPress’ core … Read more
First of all, <?php post_class(); ?> function prints a string that contains html ‘class’ attribute. So, whenever you are using this function inside class attribute, then you are actually printing another class attribute inside class attribute. That’s why your class is not working. Secondly, since <?php the_content(); ?> function may contains <p> tag, that’s why … Read more
get_month_link() doesn’t use any template. It just creates a link to date based archives. The actual template used is decided by a rather complicated template hierarchy system managed by Core. Essentially there is a cascading sequence of files that will be used if those files are provided by the theme: date.php archive.php index.php
Is the image in a child theme? If so, use get_stylesheet_directory_uri() instead as it will grab the child theme URL. get_template_directory_uri() grabs the parent theme. Depending on your PHP version adding a semicolon also might make a difference, and typically image src uses double quotes rather than single. <img src=”https://wordpress.stackexchange.com/questions/286570/<?php echo get_stylesheet_directory_uri(); ?>/img/no_results_found.png” />
