The way you’ve done it above should work. Once a variable is declared in global scope, it should be globally available (of course, your functions still need to declare it as a global: global $x;). You could also use the $GLOBALS superglobal variable: global $x; $x->var; is the same as $GLOBALS[‘x’]->var; I personally would use … Read more
$port_query->the_post(); should set the $post global. That isn’t the problem. The problem is that the you are trying to use $post before your secondary Loop runs (99% sure). You’ve hooked the bkg_featured_image() function to wp_head. wp_head runs in the header of the document, which, unless you are careful, will run before the other template code. … Read more
First function works fine, because comment form is displayed just after post. So it’s the same request and global variable post still contains current post. On the other hand, comment_post is run in another request – a POST request containing the newly added comment. So there is no global post object, because no post should … Read more
In order to access a variable defined in the global scope you must reference it with the global keyword wherever you want to call it again. In your case, the function create_year_terms() must call the global $year_arr within its scope. Also, you can always get your variable in the global scope by using the $GLOBALS … Read more
The global variable $post will be set to the first post in the main query. When any Loop runs (assuming it is constructed correctly), whether the main Loop or any number of secondary ones, $post will be set to each post in that/those loops in turn. At the end of the Loop, it will be … Read more
Before trying to write to the database, always validate the values you’re putting in: $fValid = true; if ( !isset( $payment->status ) ) { echo ‘Error: Payment status is not set’; $fValid = false; } if ( !isset( $order_id ) ) { echo ‘Error: Order ID is not set’; $fValid = false; } if ( … Read more
You should consider hooking into the comment_class() and post_class() filters, if your theme supports it. Using the comment_class filter: We can add the following filter: /** * Add a custom comment class, based on a given comment author’s user meta field. * * @see http://wordpress.stackexchange.com/a/170443/26350 */ add_filter( ‘comment_class’, function( $classes, $class, $comment_id, $post_id ) { … Read more
As you can see here, $wp_registered_widgets is defined in wp-includes/widgets.php (as expected). You should be able to debug it by doing something like this: function yoast_print_active_widgets() { global $wp_registered_widgets; echo ‘<pre>’.print_r( $wp_registered_widgets, 1 ).'</pre>’; } add_action(‘init’,’yoast_print_active_widgets’); Then you could loop through the different stages, from init, to send_headers to wp_head and see where stuff goes … Read more
What you are looking for is a “MU-Plugin”– “Must-Use Plugin”.. Originally these were called “Multi-User Plugins” and were intended for exactly your purpose– to provide a way for site admins to enable functionality on all sites of an installation. Create a directory at /wp-content/mu-plugins/ and put your PHP file(s) in it. WordPress will load the … Read more
The issue is that WP customizer submits the changes, but has not processed these yet at that point in time. If you cant wait for WP customizer to do it’s thing by using a later action, here is a solution where you get the customized information and use it to overwrite the information we had. … Read more
