posts_per_page制限なし

子テーマ関数ファイルから:

 add_action( 'pre_get_posts', 'wpsites_no_limit_posts' );

function wpsites_no_limit_posts( $query ) {

if( $query->is_main_query() && !is_admin() && is_home() ) {

$query->set( 'posts_per_page', '-1' );
$query->set( 'order', 'ASC' );
$query->set( 'post_type', 'post' );
$query->set( 'cat', '22,47,67' );
$query->set( 'orderby', 'name' );
$query->set( 'order', 'ASC' );
$query->set( 'hide_empty', '1' );
$query->set( 'depth', '1' );

    }

}
 

From your child themes functions file:

add_action( 'pre_get_posts', 'wpsites_no_limit_posts' );

function wpsites_no_limit_posts( $query ) {

if( $query->is_main_query() && !is_admin() && is_home() ) {

$query->set( 'posts_per_page', '-1' );
$query->set( 'order', 'ASC' );
$query->set( 'post_type', 'post' );
$query->set( 'cat', '22,47,67' );
$query->set( 'orderby', 'name' );
$query->set( 'order', 'ASC' );
$query->set( 'hide_empty', '1' );
$query->set( 'depth', '1' );

    }

}

リカルドをいくつか変更して使用する:

 static $paged;
$post_ids = [];
do {
    $paged++;
    $defaults = [
        'fields' => 'ids', // Only return the ID field to make this query faster.
        'post_type' => 'post',
        'posts_per_page' => 100,
        'no_found_rows' => false, // We need pagination & the count for all posts found.
        'paged' => $paged,
        'update_post_term_cache' => false,
        'update_post_meta_cache' => false,
    ];
    $query = new WP_Query($defaults);
    if ($query->have_posts()) {
        foreach ($query->posts as $id) {
            $post_ids[] = $id;
        }
    }
} while ($query->max_num_pages > $paged);

return $post_ids;
 

これにより、ID行に対してのみクエリを実行し、用語とメタキャッシュの更新を回避することで、クエリ時間が大幅に増加します.

Using Ricardo's with some modification:

static $paged;
$post_ids = [];
do {
    $paged++;
    $defaults = [
        'fields' => 'ids', // Only return the ID field to make this query faster.
        'post_type' => 'post',
        'posts_per_page' => 100,
        'no_found_rows' => false, // We need pagination & the count for all posts found.
        'paged' => $paged,
        'update_post_term_cache' => false,
        'update_post_meta_cache' => false,
    ];
    $query = new WP_Query($defaults);
    if ($query->have_posts()) {
        foreach ($query->posts as $id) {
            $post_ids[] = $id;
        }
    }
} while ($query->max_num_pages > $paged);

return $post_ids;

This will dramatically increase the query time by only querying against the ID row and avoiding updating term and meta cache.

あなたの問題に対する正しい答えは'posts_per_page' => -1は、-1が他のユーザーの回答に応じて、ページごとに無制限の投稿を返すためです.

このQ/Aにアドオンを追加したいだけです

WordPress管理パネルの読み取り設定からページあたりの投稿数を取得する場合は、get_option()関数を呼び出し、posts_per_pageをとして渡す必要があります.それに文字列.

 $args = array(
    'post_type'      => 'post',
    'cat'            => '22,47,67',
    'orderby'        => 'name',
    'order'          => 'ASC',
    'hide_empty'     => 1,
    'depth'          => 1,
    'posts_per_page' => get_option('posts_per_page')
    );

The right answer for your issue is 'posts_per_page' => -1 because -1 will return unlimited posts per page As the others users answer.

I just want to add an add-on to this Q/A,

If you want to get the number of posts per page from the reading setting on WordPress Administration Panel you have to call the get_option() function and pass posts_per_page as a string to it.

$args = array(
    'post_type'      => 'post',
    'cat'            => '22,47,67',
    'orderby'        => 'name',
    'order'          => 'ASC',
    'hide_empty'     => 1,
    'depth'          => 1,
    'posts_per_page' => get_option('posts_per_page')
    );

I hope this answer will help someone as it help me. Happy Coding Stackexchange Users

または..

 function getAll($arg, $posts_per_page = 50)
{
    $data = array();
    $page = 1;

    do{
        $arg['paged'] = $page;
        $arg['posts_per_page'] = $posts_per_page;

        $query = new WP_Query($arg);

        foreach ($query->posts as $post){
            $data[] = $post;
        }

        $page++;

    }while(count($query->posts) === $posts_per_page);

    return $data;
}
 

Or..

function getAll($arg, $posts_per_page = 50)
{
    $data = array();
    $page = 1;

    do{
        $arg['paged'] = $page;
        $arg['posts_per_page'] = $posts_per_page;

        $query = new WP_Query($arg);

        foreach ($query->posts as $post){
            $data[] = $post;
        }

        $page++;

    }while(count($query->posts) === $posts_per_page);

    return $data;
}
