1 If you look at the source code of get_the_title you will see that there is no difference between the two ways of writing the same thing, because if you call it without a parameter it is supposed to be the current ID. 2 There is no substantial difference between the two loops you use. … Read more
Since you’re not displaying a different amount of posts on the front page and on the paged pages for your main query, you don’t really need to mess around with the offset. All you need is to exclude the three posts you’ve already shown from your query, which you can do with the pre_get_posts action: … Read more
I guess my question is when are is_singular() && in_the_loop() both true? Note that both is_singular() and in_the_loop() point to the main WordPress query set via wp() (see Query Overview on WordPress Codex) which uses the global $wp_query variable. Secondly, we create/start a loop when we call have_posts() and the_post(), and only after that would … Read more
The idea is to ensure that all the content is displayed properly. Some functions are not available outside of The Loop, as it’s called, so depending on what you are doing, it may be advantageous to start the loop, even if you’re relatively certain it will only be used for one post object.
An example, that uses the posts_where filter. If you need to extend a query using the posts_clauses filter, then just exchange $where with $pieces and set $pieces[‘where’] .= instead of $where .=. Just drop that into your functions.php file and add some conditional tag before querying the posts. function filter_where( $where ) { // Add … Read more
Pretty sure query_posts is the worst way to query… Always use get_posts from what I’m constantly told. Remove the arguments that you don’t use on the array below. $args = array( ‘posts_per_page’ => 5000, ‘offset’ => 0, ‘category’ => , ‘orderby’ => ‘post_date’, ‘order’ => ‘ASC’, ‘include’ => , ‘exclude’ => , ‘meta_key’ => , … Read more
The global $post object exists already for singular views before wp_head is called. It is just not filled with all data. The the_title() calls get_the_title() which in turn calls get_post(). And that calls $GLOBALS[‘post’] if no post ID has been passed. See also Generating the ogp tags in theme for a use case.
Including Loop is not necessary, but recommended. Also, if you want to use some features you need the loop, for example: <?php if (have_posts()) : while (have_posts()) : the_post(); ?> <?php the_content(); ?> <?php endwhile; endif; ?>
First we should talk about why you need to use wp_reset_query() in the first place. What wp_reset_query() does is reset the global $wp_query object back to it’s original state. Since you’re creating a new WP_Query object / instance, it does not overwrite the global $wp_query object. The only real case you would need to call … Read more
