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
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
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
There are many errors and bad practices in your code. I’ve fixed most of them. Explaining all those here is not possible. I’ve written the explanation as comment where they need to. Please read the whole code and comments attentively- custom.js // Wrap any jQuery code like this. It makes ‘$’ use fullproof // and … Read more
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
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
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
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
2 choices here, you either need to set the category as an array e.g. $args = array( ‘posts_per_page’ => 5, ‘category’ => array(15,16,17,18,19) ); You can’t just add the numbers in a list but I can’t find any documentation that the category element allows multiples (as the name is category) The other option is to … Read more
Put the following code in your functions.php file. function limit_posts_per_page() { if ( is_author() ) // you can limit other pages as well ( i.e. is_archive() ), if need be. return 5; } add_filter( ‘pre_option_posts_per_page’, ‘limit_posts_per_page’ ); Make sure your using the author.php template, otherwise it wont work. Please have a look at twentyten’s author.php … Read more
