It is all fine. You just need to declare variable global first then you can set the value of this and access globally. function my_free_shipping( $is_available ) { global $woocommerce, $product_notfree_ship; // set the product ids that are $product_notfree_ship $product_notfree_ship = array( ‘1’, ‘2’, ‘3’, ‘4’, ‘5’ ); Then again declare it globally when using … Read more
As @Milo brilliantly pointed out, there is no such a thing like a global query object in WordPress. So I’ve solved the problem via JS, like this: var isFiltered = false; var filters; $(load_more_button).click(function(e) { load_more_handler(e); }); $(filters_form).submit(function(e) { filter_handler(e); }); function filter_handler(e) { isFiltered = true; filters = $(this).serialize(); var data = { action: … Read more
Try: register_activation_hook ( __FILE__, array( new MemorialCandles(), ‘dbInstall’ ) ); Or define dbInstall as ´static´ and use that to set the table name instead the constructor, which I think is the best approach.
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
