Here is a fast example using get_categories instead of a plugin or the walker class, maybe it will help you in the right direction, it will list all children of a parent category in json format. As brasofilo mentions since you require a specific format you will want to build a custom array. // let’s … Read more
You can filter category_link and replace the URL here. I have used the newest post in the following example, because first could also mean the oldest and that sounds … strange. 🙂 add_filter( ‘category_link’, ‘wpse_96677_cat_link_to_first_post’, 10, 2 ); function wpse_96677_cat_link_to_first_post( $url, $term_id ) { $term = get_term( $term_id, ‘category’ ); // sub-terms only if ( … Read more
That’s a really inefficient way to do it. Just use the $count variable you declared at the top, without any query_posts(): $count = 0; while ( have_posts() ) : the_post(); if ( $count < 1 ) { // first post } elseif ( $count <= 4 ) { // next 4 posts } else { … Read more
You can use Custom Post Type Permalinks extension. Open breadcrumbs settings and add /%project_category% in Permalink Settings for Custom Post Types. Save. Done. That’s how I figured it out.
There are a lot of questions here regarding pagination, it is definitely one of the least understood aspects of how WordPress works internally. To understand why you get 404s, we’ll start by looking at the Action Reference in Codex to see the process WordPress follows for each request. The process begins by loading up the … Read more
You don’t need complicated filters to modify the SQL query, just use the order parameter of WP_Query ( avoid query_posts, your code above will trigger multiple unused queries, making the page very slow ) $q = new WP_Query( [ ‘order’ => ‘rand’ ] ); You can pass an integer seed too: $q = new WP_Query( … Read more
You cannot have duplicate slugs or taxonomies, to remove the number you will need to delete them. There is a database hack to have duplicate terms but it’s probably not a great idea, Removing the number in a category slug
Got it to work, finally! Nothing like a good sleep to restart your brain 🙂 Updated code that works: $item_output = $args->before; if( $item->object == ‘category’ ) { $category = get_category( $item->object_id ); $category_color = get_field( ‘category_color’, $category); $item_output .= ‘<a style=”color:’ . $category_color . ‘;”‘. $attributes .’>’; } else { $item_output .= ‘<a’. $attributes … Read more
Solved, thanks to nofearinc on the wp.org irc chat! 🙂 https://gist.github.com/mpeshev/cb1cd3c56d06017b3d87 <?php $cat_id = get_query_var(‘cat’); if( ! empty( $cat_id ) ) { $category = get_category( $cat_id, ARRAY_A ); if( ! empty( $category ) ) { // parent category if( $category[‘parent’] === ‘0’ ) { // get child IDs $terms = get_term_children( $cat_id, ‘category’ ); foreach( … Read more
In your category.php ( or custom taxonomy archive template ), you should add the form code in the else case of your check if there are posts e.g. if(have_posts()){ // do the post loop } else { // display a form that takes user details for future posts } If there is no category.php you … Read more
