Find One

The find_one() family of functions are wrappers for common WordPress retrieval functions like get_posts() or get_terms() that reduce the return value of those retrieval functions into a single result.

Installation

Install the latest version with:

composer require alleyinteractive/wp-find-one

Basic usage

To find one item in a person post type:

<?php

use function Alley\WP\find_one_post;

// Returns a \WP_Post or null.
$person = find_one_post(
    [
        'meta_key'   => 'twitter',
        'meta_value' => '@potatomaster',
        'post_type'  => 'person',
    ]
);

which is equivalent to:

<?php

$person = \get_posts(
    [
        'meta_key'         => 'twitter',
        'meta_value'       => '@potatomaster',
        'post_type'        => 'person',
        'posts_per_page'   => 1,
        'suppress_filters' => false,
    ]
);

if ( ! empty( $person[0] ) ) {
	$person = $person[0];
}

Taxonomy terms can be searched for similarly:

<?php

use function Alley\WP\find_one_term;

// Returns a \WP_Term or null.
$category = find_one_term(
    [
        'slug'     => 'potatomaster',
        'taxonomy' => 'category',
    ]
);

which is equivalent to:

<?php

$category = \get_terms(
    [
        'number'   => 1,
        'slug'     => 'potatomaster',
        'taxonomy' => 'category',
    ]
);

if ( ! empty( $category[0] ) ) {
	$category = $category[0];
}

The underlying find_result() function accepts the fully qualified class name of the object to search for and the array of query results:

<?php

use function Alley\WP\find_result;

// Returns a \WP_Network or null.
$network = find_result( \WP_Network::class, \get_networks() );

Helper functions are available for all core WordPress data types that have meta tables:

• find_one_comment()
• find_one_post()
• find_one_site()
• find_one_term()
• find_one_user()
