when you use get_template_part, your file navigation.php cannot access variable $navigation_type. but when you do include and locate_template it is simply like including a php file so it can access that variable. It is due to scope of variable in your context.
I see no reason for this to not work technically, only you don’t need those single quotes around variable. But practically why not just use page-{slug}.php or other template option from hierarchy?
The filename of the template chosen for pages is saved in a post meta field called _wp_page_template, which you can get e.g. like this: $template_filename = get_post_meta( get_the_ID(), ‘_wp_page_template’, true ); Now you have a file name like example-template.php, with it you can determine which template to load, if you named it right, so you … Read more
If your comments in the code above reflect the file names then it’s a dash vs. underscore mistake. Name of the second included file should be query-default.php
In category-about.php I have <?php /** * The template for displaying the posts in the About category * */ ?> <!– category-about.php –> <?php get_header(); ?> <?php $args = array( ‘post_type’ => ‘post’, ‘category_name’ => ‘about’, ); ?> <?php // important bit set_query_var( ‘query_category’, $args ); get_template_part(‘template-parts/posts’, ‘loop’); ?> <?php get_footer(); ?> and in template … Read more
get_template_part() will work the same no matter where or how deep you are within your theme. It always includes relative to the theme (or child theme) root. So if you call the following from anywhere: get_template_part( ‘content’, ‘job-listing’ ); … it will try to load (in order): child-theme/content-job-listing.php parent-theme/content-job-listing.php child-theme/content.php parent-theme/content.php To load parts that … Read more
In my opinion three or four calls of get_template_part() is perfectly acceptable and even within the norm for some of the larger and more complex themes out there. I don’t know how many is too many but I think it would have to be a pretty large number to notice a hit in performance. A … Read more
This is not a true solution to your problem (checking which template loaded another), but it will work to test if the footer has been loaded or not, and thus if it’s loading your partial: if ( did_action( ‘get_footer’ ) ) echo ‘footer-class’;
It does, by default. The get_template_part() function uses locate_template() which cascades through the template files in in order of specificity and stylesheetpath/templatepath. So, if your Child Theme includes a content-inventory.php, then get_template_part() will include it; if not, then it will look for content-inventory.php in the parent Theme. If it doesn’t find it, it will then … Read more
There isn’t a core global variable that returns the current context. However, you can construct your own, using contextual template conditional tags. You can step through the conditional tags in the same order as WordPress core, by following wp-includes/template-loader.php. Simply wrap your output in a custom Theme function. Here’s how I do it (note: I … Read more
