1. get_posts- The WordPress get_posts function provides a way to get a specific group of posts depending on given parameters.
- It's essential to remember that posts in this context also refer to pages or custom post types. Afterward, the page can display the get_posts query's results.
- To translate the PHP code into a SQL query to the database of your WordPress site, "get_posts takes your search criteria and then works inside the WP_Query object."
- Syntax: get_posts()
- Example:
'numberposts' => 18,
'category' => 8
);
$all_posts = get_posts( $args );
The above function retrieves the latest 18 in the specified category.
2. WP_Query- The PHP class WP_Query can be used to create queries for your database. This built-in class in WordPress appears whenever someone searches for your content.
- Users may use a custom WordPress query to locate particular content quickly. A WP_Query custom post type makes it simple to render a specific set of posts on the front end of your website.
- Developers can also benefit from WP_Query. You can modify WordPress themes using this PHP class without directly querying the database.
- Several content types, such as posts, pages, attachments, and custom post types, can be obtained via it.
- WP_Query returns an object you may loop through to show the content you retrieved.
- Syntax: $query = new wp_query($args);
- Example:
'post_type' => 'post', // Specify the post type
'posts_per_page' => 10, // Number of posts to retrieve
'orderby' => 'date', // Order posts by date
'order' => 'DESC', // Sort in descending order
'category__not_in' => array(2), // Exclude posts from specific category
);
$query = new WP_Query($args);
if ($query->have_posts()) {
while ($query->have_posts()) {
$query->the_post(); // Display post content here
}
wp_reset_postdata(); // Restore original post data
}
