Just use the parameter category__in of WP_Query – if you do this, then there is no need for cat and category__not_in. category__in does give you back results from the categor(y/ies) specified, but does not include results for the children of the specified categor(y/ies).
EDIT 2 – FINAL EDIT Just before I start with this edit, just a few things here The code in my answer are the basics and meant to demonstrate the concepts. I have now tested both sets of code, and all works as expected. You have to add all your desired mark-up, styling and template … Read more
First off, you should not be handing an untrusted input (in this case, $_GET[‘id’] to your database. Always SQL-escape the query and validate/sanitize the data. (In the code snippet below, it’s SQL-escaped using $wpdb->prepare() for escaping and int typecasting to sanitize to integer value). Secondly, the $wpdb object provides more than just the query() function. … Read more
The ‘posts_per_page’ => -1, and ‘nopaging’ => true, shouldn’t be in your tax_query params. That might be what’s throwing it off. Try: $args = array( ‘post_type’=>’gpp_prod’, ‘orderby’ => ‘title’, ‘order’ => ‘ASC’, ‘posts_per_page’ => -1, ‘nopaging’ => true, ); and: $args[‘tax_query’] = array( array( ‘taxonomy’ => ‘cat_prod’, ‘field’ => ‘term_id’, ‘terms’ => $category ) );
The following code will properly store data in wp_fafa: $wpdb->insert( $wpdb->prefix . ‘fafa’, array( ‘title’ => trim($row->item(0)->nodeValue), ‘liveprice’ => trim($row->item(2)->nodeValue), ‘changing’ => trim($row->item(4)->nodeValue), ‘lowest’ => trim($row->item(6)->nodeValue), ‘topest’ => trim($row->item(8)->nodeValue), ‘time’ => trim($row->item(10)->nodeValue) ), array( ‘%s’, ‘%s’, ‘%s’, ‘%s’, ‘%s’, ‘%s’ ) );
I would rather use a full proper tax_query here. The {tax} syntax is depreciated according to the docs A tax_query is also better here as you will be dealing with an array of terms. When your URL is http://www.myWebsiteURL.com/lessons this means that all terms should be displayed. So this means that you need to use … Read more
You cannot insert the do_action() inside the class like that, it’s gonna give you a fatal error. Instead you could use an array $skins to store all the skin functions (as closures), and the magic method _call() to call them: class skinclass { private $skins = array(); function __construct() { $this->skins = apply_filters( ‘add_skin’, $this->skins … Read more
This is not how pre_get_posts works. The pre_get_posts action gives developers access to the $query object by reference (any changes you make to $query are made directly to the original object – no return value is necessary). https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts What you are doing is simply wrong. You don’t “return” another query via pre_get_posts, you alter the … Read more
Your logic in your code is wrong. Read your code in plain English. If the current post is number 3, show my custom content, else, show the posts as normal. What you want is the following If the current post is number 3, show my custom content. Show all my posts as normal To achieve … Read more
<?php $args = array( ‘posts_per_page’ => -1, ‘post_type’ => ‘event’, ‘meta_query’ => array( array( ‘key’ => ‘event_date_end_timestamp’, ‘value’ => time(), ‘type’ => ‘numeric’, ‘compare’ => ‘<‘ ) ) ); $programs = new WP_Query($args); ?> <?php while($programs->have_posts()): $programs->the_post(); ?> <h1><?php the_title(); ?></h1> <?php endwhile; ?>
