-1 is your answer! Look for posts_per_page here.

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

Important caveat: This can result in a very huge query that can bring the site down. Do this only if you are sure your database can handle it. Not in public themes or plugins.

In alternativa,puoipassare WP_Query (che è ciò che query_posts usa) l'argomento nopaging,chefondamentalmentefa la stessa cosa ..

 $args = array(
    'nopaging' => true
    // Your other args, etc..
);
 

Faràesattamente lo stesso,ma se devi ripensarcipiùtardie non ricordi cosa stavifacendo,personalmente ritengo cheti saràpiù chiaro cosaintendevi con quelparametroall'interno dell'array args.

Come hogià detto,tuttavia,entrambi otterranno lo stesso risultato.

Nonpuòfarmale averepiù di un approccio,ed è semprebello condividere ciò che sai,basti dire che è questoilmotivo dellamia risposta,nonostantetune abbiagià uno sufficiente ..;)

Or alternatively you can pass WP_Query(which is what query_posts uses) the nopaging argument, which basically does the same thing..

$args = array(
    'nopaging' => true
    // Your other args, etc..
);

It will do exactly the same, but if you have to look back at it later and can't remember what you were doing, i personally feel it will be more clear to you, what it is you were intending with that parameter inside the args array.

As i mentioned however, they'll both actually achieve the same.

Can't hurt to have more than one approach, and it's always nice to share what you know, suffice to say that's the reason for my answer, despite you already having a sufficient one.. ;)

Dalfile dellefunzioni deitemi figlio:

 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' );

    }

}

Utilizzo di Ricardo con alcunemodifiche:

 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;
 

Ciò aumenterànotevolmenteiltempo di queryeseguendo query solo sulla riga IDedevitando di aggiornarei terminie lameta cache.

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.

La rispostagiustaperiltuoproblema è 'posts_per_page' => -1perché -1 restituirà unnumeroillimitato dipostperpagina come rispondonogli altri utenti.

Voglio solo aggiungere un componente aggiuntivo a questa domanda/risposta,

Se desideri ottenereilnumero dipostperpagina dalleimpostazioni di lettura sulpannello di amministrazione di WordPress,devi chiamare lafunzione get_option()e passare posts_per_page comestringa adesso.

 $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

Oppure ..

 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;
}
