Query

Query is an abstraction layer for WP_Query.

Query makes it easier to interact with WP_Query. It also makes code much more readable.

Use Cases

A little less conversation a little more action.

Get all posts

<?php 
use WPExpress\Query;

$allPosts = Query::Post()->all()->get();
$allCustomPosts = Query::Custom('book')->all()->get();

Get 10 posts

<?php 
use WPExpress\Query;

// Note: If limit is not set defaults to 10 using ***showposts*** parameter
$tenPosts = Query::Post()->limit(10)->get();
$tenBooks = Query::Custom('book')->limit(10)->get();

Get posts by Meta Value (Custom Field)

<?php 
use WPExpress\Query;

$tenPosts = Query::Post()->meta('fieldName', 'value')->get();
$tenBooks = Query::Custom('book')->meta('fieldName', 'value')->get();

//Note: You can also use and array as value
$somePosts = Query::Post()->meta('fieldName', array( 'value', 'value2' ) )->all()->get();

Get posts without Meta Value

<?php 
use WPExpress\Query;

// The method meta takes a third operator indicating the comparison to be used. In this case **NOT**
$somePosts = Query::Post()->meta('fieldName', array( 'value', 'value2' ), 'not' )->all()->get();
$someBooks = Query::Custom('book')->meta('fieldName', 'value', 'not' )->all()->get();

Get posts by Taxonomy

<?php 
use WPExpress\Query;

$tenPosts = Query::Post()->term('taxonomy', 'value')->get();
$tenBooks = Query::Custom('book')->term('taxonomy', 'value')->get();

Insert, Delete, Save

<?php 
use WPExpress\Query;

// TODO: Add code here

Methods

Ok, that was fun. Now, lets explain the methods a little.

all and limit

all and limit indicate how many posts should WordPress retrieve from the DataBase. As you can expect all indicates every post should be retrieved, while limit indicates the number of posts to be retrieved.

<?php 
use WPExpress\Query;

$allPosts = Query::Post()->all()->get();
$fivePosts = Query::Post()->limit(5)->get();

meta

<?php 
use WPExpress\Query;

// TODO: Add code here

term

<?php 
use WPExpress\Query;

// TODO: Add code here

get, get first, get last

<?php 
use WPExpress\Query;
