WordPress Args - PHP

WordPress args is a function in PHP that is used to specify arguments for certain WordPress tasks, such as creating a custom post type or querying posts.

The basic syntax for using args is:

$args = array(
	'argument1' => 'value1',
	'argument2' => 'value2',
	// add more arguments here as necessary
);

Once the arguments are defined, they can be passed to various WordPress functions. For example, to create a custom post type, the args would be passed to register_post_type() function like this:

$labels = array(
	'name' => __( 'Custom Post Type', 'textdomain' ),
	'singular_name' => __( 'Custom Post', 'textdomain' ),
);

$args = array(
	'labels' => $labels,
	'public' => true,
	'has_archive' => true,
);

register_post_type( 'custom_post_type', $args );

In this example, the $labels and $args variables are defined and then passed as parameters to the register_post_type() function. The args include specific settings for the custom post type, such as the labels to use for display and whether the post type is public or not.

Other popular WordPress functions that use args include get_posts(), wp_query() and register_taxonomy(). The args passed to these functions can be used to filter, sort or otherwise manipulate the output.

One important thing to note is that the args syntax can vary depending on the function being used. For instance, the args used to create a custom post type may be different from the args used to create a custom taxonomy.

In summary, wordpress args is a powerful and flexible tool for customizing WordPress features and functionality. By properly using args, developers can create custom post types, queries, and other features tailored to the specific needs of their clients or projects.

Code Sample

$args = array(
	'post_type' => 'my_custom_post_type',
	'posts_per_page' => 5,
	'order' => 'DESC',
);

$custom_query = new WP_Query( $args );

if ( $custom_query->have_posts() ) :
	while ( $custom_query->have_posts() ) : $custom_query->the_post();
		// Do Stuff with each post
	endwhile;
else :
	// No posts found
endif;

wp_reset_postdata();

In this example, we use WP_Query() with args to create a custom query for my_custom_post_type that displays 5 posts in reverse chronological order. We then use while and have_posts() to loop through the query and display our posts. Finally, we use wp_reset_postdata() to restore the default post data.
