USAGE

元数据查询

获取元数据 "color" 为 "blue" 或者 "size" 为 "XL" 的所有文章类型中的文章

       $builder = new Builder();
       $wp_query = $builder->createMetaQuery("OR")
                            ->addMetaQuery(MetaQuery::create('color', 'blue'))
                            ->addMetaQuery(MetaQuery::create('size', 'XL'))
                            ->getWPQuery();

获取元数据 "price" 大于等于 "10" 并且 "size" 为 "XL" 的所有文章类型中的文章

       $builder = new Builder();
       $wp_query = $builder->createMetaQuery("AND")
                            ->addMetaQuery(MetaQuery::create('price', 10, '>=', 'NUMERIC'))
                            ->addMetaQuery(MetaQuery::create('size', 'XL'))
                            ->getWPQuery();  

Retrieve any post type where post meta price is equal or greater than 10 AND (size meta value equals to XL OR post meta color value equals to blue)

       $builder = new Builder();
       $builder->createMetaQuery("AND")
               ->addMetaQuery(MetaQuery::create('price', 10, '>=', 'NUMERIC'));
                    
       $condition = new MetaQueryCollection('OR');
       $condition->add(MetaQuery::create('color', 'blue'))
                 ->add(MetaQuery::create('size', 'XL'));
                 
                 
       $wp_query = $builder->addMetaQueryCollection($condition)
                           ->getWPQuery();  

自定义分类法查询

Retrieve the contents under ("pets" OR "tools") values in the "category" taxonomy AND in under 'sweet' in "custom" taxonomy

       $builder = new Builder();
       $wp_query = $builder->createTaxonomyQuery("AND")
                            ->addTaxonomyQuery(TaxonomyQuery::create('category', 'slug', array('pets', 'tools')))
                            ->addTaxonomyQuery(TaxonomyQuery::create('custom', 'slug', array('sweet')))
                            ->getWPQuery();

Retrieve the contents under ("pets" OR "tools") values in the "category" taxonomy BUT exclude contents in their children

       $builder = new Builder();
       $wp_query = $builder->createTaxonomyQuery("AND")
                            ->addTaxonomyQuery(TaxonomyQuery::create('category', 'slug', array('pets', 'tools'), false))
                            ->getWPQuery();

Retrieve the contents those are NOT under ("pets" OR "tools") values in the "category" taxonomy

       $builder = new Builder();
       $wp_query = $builder->createTaxonomyQuery("AND")
                            ->addTaxonomyQuery(TaxonomyQuery::create('category', 'slug', array('pets', 'tools'), true, 'NOT IN'))
                            ->getWPQuery();

You can have nested relations too

      $builder = new Builder();
      
      $collection = new TaxonomyQueryCollection('OR');
      $collection->add(TaxonomyQuery::create('tag', 'slug', array('cats')));
      $collection->add(TaxonomyQuery::create('custom', 'slug', array('sweet')));
      
      $wp_query = $builder->createTaxonomyQuery("AND")
                           ->addTaxonomyQuery(TaxonomyQuery::create('category', 'slug', array('pets', 'tools')))
                           ->addTaxonomyQueryCollection($collection)
                           ->getWPQuery();     

文章类型

Retrieve all PAGES

       $builder = new Builder();
       $wp_query = $builder->addPostType(Builder::POST_TYPE_PAGE)
                           ->getWPQuery();

Retrieve all CUSTOM POST TYPE

       $builder = new Builder();
       $wp_query = $builder->addPostType('your_custom')
                           ->getWPQuery();

Retrieve all CUSTOM POST TYPE and PAGES

       $builder = new Builder();
       $wp_query = $builder->addPostType('your_custom')
                           ->addPostType(Builder::POST_TYPE_PAGE)
                           ->getWPQuery();

搜索

        $builder = new Builder();

        $wp_query = $builder->search("search query")
                            ->getWPQuery();

IN and NOT IN

Retrieve contents with ID in array of IDS

        $builder = new Builder();

        $wp_query = $builder->inPostIDs(array(1,2,3))
                            ->getWPQuery();

Retrieve contents with ID not in array of IDS

        $builder = new Builder();

        $wp_query = $builder->notInPostIDs(array(1,2,3))
                            ->getWPQuery();

ORDERBY

Order contents by title descending

        $builder = new Builder();

        $wp_query = $builder->setOrderBy("title")
                            ->getWPQuery();

Order contents by date, ascending

        $builder = new Builder();

        $wp_query = $builder->setOrderBy("date")
                            ->setOrderDirection("ASC")
                            ->getWPQuery();

Order contents by title descending and date, ascending

        $builder = new Builder();

        $wp_query = $builder->addOrderBy("title", "DESC")
                            ->addOrderBy("date", "ASC")
                            ->getWPQuery();

Order contents by custom meta

        $builder = new Builder();

        $wp_query = $builder->setOrderByMeta("color", "DESC")
                            ->getWPQuery();

Order contents by custom numeric meta

        $builder = new Builder();

        $wp_query = $builder->setOrderByMeta("price", "ASC", true)
                            ->getWPQuery();

LIMITS AND OFFSETS

Retrieve only 10 contents

        $builder = new Builder();

        $wp_query = $builder->setLimit(10)
                            ->getWPQuery();

Retrieve 20 contents starting from the 10th position

        $builder = new Builder();

        $wp_query = $builder->setLimit(20)
                            ->setOffset(10)
                            ->getWPQuery();

RETRIEVING

Get the WPQuery object

        $builder = new Builder();

        $wp_query = $builder->getWPQuery();

Get the Posts array

        $builder = new Builder();

        $posts = $builder->getPosts();

Get the WPQuery parameters array

        $builder = new Builder();

        $params = $builder->getParameters();
        
        $query = new WP_Query($params);

Get an array containing only the post IDs. This is useful when you want to return all records without pagination from a large recordset in order to avoid memory issues.

        $builder = new Builder();

        $ids = $builder->getPostIDsOnly();
        
        $builder = new Builder();
        
        $wp_query = $builder->inPostIDs($ids)
                            ->getWPQuery();
