setup_postdata doesn`t seem ot be working

According to the Codex, you seem to skip the most important global $post; at the beginning, like this: global $post; $posts = get_posts($args); foreach($posts as $post) { setup_postdata($post); ?> <article class=”col two tablet-four mobile-six box”> <a href=”https://wordpress.stackexchange.com/questions/131909/<?php the_permalink(); ?>” title=”<?php the_title_attribute(); ?>”> <div class=”featured-image”> <?php if(has_post_thumbnail(get_the_ID())): ?> <?php $image = wp_get_attachment_image_src(get_post_thumbnail_id(get_the_ID()), array(650,200)); ?> <div style=”background: … Read more

Can I set and show “important” post in my blog?

Yes of course. One of the ways to achieve this is by adding an extra category to your posts which you call ‘sticky’ or ‘important’ or something like that. For the example I will choose ‘important’. To only get the important posts you can write a loop which loops through this category. For example: <?php … Read more

Query random post from different categories

Random ordering is quite expensive operations in SQL and can become a headache on very big sites. Getting a random post from a category for 6 categories will mean you might need to run 6 separate queries, each ordered randomly. This can really break the bank and leave you bankrupt. From your answer and looking … Read more

When to use an if statement after get_posts?

In my opinion we cannot guarantee the post existence in db for a specific query. maybe it returns an empty array. so its best practice to use the conditional statement. plus i think we are dealing with an array so to check the empty array we should use php empty function. for example: if ( … Read more

Is there a get_post(s) filter that can alter/replace the output completely?

If you look towards the end of the query process (which starts with the pre_get_posts filter), there is a filter called the_posts (not to be confused with the_post). This allows you to modify the output of get_posts completely, as you asked. Beware that this only works if there is no plugin or so that suppresses … Read more

WP_Query, tax_query and term_meta: How to?

AFAIK there’s no way to achieve that within a single WP_Query, so you’ll have to first get a list of term_ids which have a different year than the one in question. I think with the following you’ll come quite close. (don’t have a env to test right away) $other_years_terms = get_terms( ‘taxonomy’ => ‘vintage’, ‘meta_key’ … Read more

How do you Query posts with nothing in common?

Maybe you’re looking for the post__in parameter in WP_Query. $query = new WP_Query(array( ‘post__in’ => array(23,18,2,199,6,8) ); And then: while ( $query->have_posts() ) { $query->the_post(); /* post loop */ } Take a look at the docs. =D For public queries: post__in is not public queryable by default, so you can just validate and copy $_GET[‘post__in’] … Read more

how to get specific page content

Rather than call WP_Query() you can use get_post() and “set up” the global $post. This is probably a little more efficient than @tf’s answer, though the ideas are broadly the same. Please note, in both cases you should reset the post data afterwards. /** * Display the post content. Optionally allows post ID to be … Read more

get_posts() returns all posts rather than the ones specified with ‘post_author’ =>

post_author is not a valid parameter for get_posts. You really need to look at WP_Query‘s argument list to see that, as get_posts() is really just a wrapper around that class. author (int) – use author id. author_name (string) – use ‘user_nicename’ (NOT name). author__in (array) – use author id (available with Version 3.7). author__not_in (array) … Read more
