How do I allow certain users to make a certain type of post?

Retrieve a specific post’s featured image and show on a different page

Each post object has a public member $post_parent. That is the post ID of the parent post. So this should work: $thumbnail=””; if ( ( ‘event_posts’ == get_post_type() || is_page( ‘events’ ) || is_page( ‘restaurants’ ) || is_page( ‘recreation’ ) || is_page( ‘entertainment’ ) ) && ! empty ( $GLOBALS[‘post’]->post_parent ) ) { $thumbnail = … Read more

Import custom database into wp and keep the post id

Is that possible put a whole POST in a list ,

Yes if (have_posts()) : while (have_posts()) : the_post(); is a loop, so you would just add the tags into it. <ul> <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <li> <div <?php post_class() ?> id=”post-<?php the_ID(); ?>”> <h2><a href=”https://wordpress.stackexchange.com/questions/95763/<?php the_permalink() ?>”><?php the_title(); ?></a></h2> <div class=”entry”> <?php the_content(); ?> </div> <div class=”postmetadata”> <?php the_tags(‘Tags: ‘, … Read more

Get only X number of categories

After reading your question (and comment) again, this could be what you want to do: $X = 3; // for instance ob_start(); the_category(); $cats = implode(‘<li’, array_slice(explode(‘<li’, ob_get_clean()), 0, $X+1)); If you want to use this throughout your theme multiple times, use a function. Put the following in your functions.php: function my_the_category($limit) { $limit++; ob_start(); … Read more

Adding a custom post type meta field to rss

Filter the_content_feed: add_filter( ‘the_content_feed’, ‘wpse_96342_add_video’ ); function wpse_96342_add_video( $feed_content ) { // fetch post meta // add to content return $feed_content; }

Count user posts and store the number for later use

You can use update_user_meta() to add information to a user’s meta fields, and count_user_posts() to get an initial count. So, for instance: <?php add_action( ‘new_to_publish’, ‘wpse96358_author_count’ ); add_action( ‘draft_to_publish’, ‘wps396358_author_count’ ); function wpse96358_author_count() { global $post; // get initial count $single = true; $author_count = get_user_meta( $post->post_author, ‘author_count’, $single ); if ( strlen( $author_count ) … Read more

Finding a post’s slug

The slug is already in the post object, it’s $post->post_name. And as you observed, yes, the way to get the post link is get_permalink( $post->ID );

Get post category as a separate string and url

First you have to find the category ID, which can be done easily with the function get_the_category(). To get the slug, use: $catID = get_the_category(); $catSlug = $catID->slug. To get the link: $catLink = get_category_link($catID).
