J'ai unmessagepersonnalisé detype "news"et j'ai dumal à lefairepaginer correctement. Je recherche un simple lienprécédentet suivant,sansm'inquiéter desnuméros depage aumilieu.

Danspage-news.php,voicimon code:

 <?php
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
    $args = array('post_type' => 'news', 'posts_per_page' => 2, 'paged' => $paged);
    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
?>

// Loop

<?php endwhile; wp_reset_postdata(); ?>

<div id="pagination" class="clearfix">
    <?php posts_nav_link(); ?>
</div>

Le code ci-dessus affiche 2 articles,mais aucun lien depagination

Voicimon code detype demessagepersonnalisé:

 function custom_post_news() {
    register_post_type( 'news',
        array('labels' => array(
            'name' => __('News', 'post type general name'), /* This is the Title of the Group */
            'singular_name' => __('News', 'post type singular name'), /* This is the individual type */
            'add_new' => __('Add New', 'custom post type item'), /* The add new menu item */
            'add_new_item' => __('Add New'), /* Add New Display Title */
            'edit' => __( 'Edit' ), /* Edit Dialog */
            'edit_item' => __('Edit'), /* Edit Display Title */
            'new_item' => __('New '), /* New Display Title */
            'view_item' => __('View'), /* View Display Title */
            'search_items' => __('Search news'), /* Search Custom Type Title */
            'not_found' =>  __('Nothing found in the Database.'), /* This displays if there are no entries yet */
            'not_found_in_trash' => __('Nothing found in Trash'), /* This displays if there is nothing in the trash */
            'parent_item_colon' => ''
        ), /* end of arrays */
            'description' => __( 'This is the example custom post type' ), /* Custom Type Description */
            'public' => true,

            'show_ui' => true,
            'query_var' => true,
            'menu_position' => 2, /* this is what order you want it to appear in on the left hand side menu */
            'capability_type' => 'post',
            'hierarchical' => false,
            'rewrite' => array('slug' => 'news', 'with_front' => true ),
            /* the next one is important, it tells what's enabled in the post editor */
            'supports' => array( 'title', 'editor', 'thumbnail')
        )
    );

}


// REGISTER TAXOMONIES

add_action( 'init', 'custom_post_news');
register_taxonomy( 'custom_news',
    array('news'), /* if you change the name of register_post_type( 'movies', then you have to change this */
    array('hierarchical' => true,
        'labels' => array(
            'name' => __( 'News Categories' ), /* name of the custom taxonomy */
            'singular_name' => __( 'news Category' ), /* single taxonomy name */
            'search_items' =>  __( 'Search news Categories' ), /* search title for taxomony */
            'all_items' => __( 'All news Categories' ), /* all title for taxonomies */
            'parent_item' => __( 'Parent news Category' ), /* parent title for taxonomy */
            'parent_item_colon' => __( 'Parent news Category:' ), /* parent taxonomy title */
            'edit_item' => __( 'Edit news Category' ), /* edit custom taxonomy title */
            'update_item' => __( 'Update news Category' ), /* update title for taxonomy */
            'add_new_item' => __( 'Add New news item' ), /* add new title for taxonomy */
            'new_item_name' => __( 'New Custom news' ) /* name title for taxonomy */
        ),
        'show_ui' => true,
        'query_var' => true,
    )
);

C'est unthèmepersonnalisé (commencé àpartir de zéro) donciln'y a rien dansmonfunctions.phpfaisant référence à unepagination. J'aiparcouru Internetpourtrouver des réponses,maisj'obtiens une solution différenteet rienne semblefonctionner.

Jen'aipasnonplus d'archive-news.php carje ne saispas si cela doit êtreimplémenté ounon?

I have custom post post type call 'news' and I am struggling to get it to paginate correctly. I'm looking for a simple prev and next links, not worried about page numbers in the middle.

In page-news.php this is my code:

<?php
    $paged = get_query_var('paged') ? get_query_var('paged') : 1;
    $args = array('post_type' => 'news', 'posts_per_page' => 2, 'paged' => $paged);
    $loop = new WP_Query( $args );
    while ( $loop->have_posts() ) : $loop->the_post();
?>

// Loop

<?php endwhile; wp_reset_postdata(); ?>

<div id="pagination" class="clearfix">
    <?php posts_nav_link(); ?>
</div>

The above code is showing 2 posts, but no pagination links

This is my custom post type code:

function custom_post_news() {
    register_post_type( 'news',
        array('labels' => array(
            'name' => __('News', 'post type general name'), /* This is the Title of the Group */
            'singular_name' => __('News', 'post type singular name'), /* This is the individual type */
            'add_new' => __('Add New', 'custom post type item'), /* The add new menu item */
            'add_new_item' => __('Add New'), /* Add New Display Title */
            'edit' => __( 'Edit' ), /* Edit Dialog */
            'edit_item' => __('Edit'), /* Edit Display Title */
            'new_item' => __('New '), /* New Display Title */
            'view_item' => __('View'), /* View Display Title */
            'search_items' => __('Search news'), /* Search Custom Type Title */
            'not_found' =>  __('Nothing found in the Database.'), /* This displays if there are no entries yet */
            'not_found_in_trash' => __('Nothing found in Trash'), /* This displays if there is nothing in the trash */
            'parent_item_colon' => ''
        ), /* end of arrays */
            'description' => __( 'This is the example custom post type' ), /* Custom Type Description */
            'public' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'show_ui' => true,
            'query_var' => true,
            'menu_position' => 2, /* this is what order you want it to appear in on the left hand side menu */
            'capability_type' => 'post',
            'hierarchical' => false,
            'rewrite' => array('slug' => 'news', 'with_front' => true ),
            /* the next one is important, it tells what's enabled in the post editor */
            'supports' => array( 'title', 'editor', 'thumbnail')
        )
    );

}


// REGISTER TAXOMONIES

add_action( 'init', 'custom_post_news');
register_taxonomy( 'custom_news',
    array('news'), /* if you change the name of register_post_type( 'movies', then you have to change this */
    array('hierarchical' => true,
        'labels' => array(
            'name' => __( 'News Categories' ), /* name of the custom taxonomy */
            'singular_name' => __( 'news Category' ), /* single taxonomy name */
            'search_items' =>  __( 'Search news Categories' ), /* search title for taxomony */
            'all_items' => __( 'All news Categories' ), /* all title for taxonomies */
            'parent_item' => __( 'Parent news Category' ), /* parent title for taxonomy */
            'parent_item_colon' => __( 'Parent news Category:' ), /* parent taxonomy title */
            'edit_item' => __( 'Edit news Category' ), /* edit custom taxonomy title */
            'update_item' => __( 'Update news Category' ), /* update title for taxonomy */
            'add_new_item' => __( 'Add New news item' ), /* add new title for taxonomy */
            'new_item_name' => __( 'New Custom news' ) /* name title for taxonomy */
        ),
        'show_ui' => true,
        'query_var' => true,
    )
);

This is a custom theme (started from scratch) so there's nothing in my functions.php referring to a pagination. I've scoured the Internet for answers, but I get a different solution and nothing seems to work.

I also don't have an archive-news.php as I'm not sure if this needs to be implemented or not?

posts_nav_link() ne fonctionnerapasici

Utilepourfournir unenavigation "paginée" despages d'index,de catégorieet d'archive.

Vous devrez utiliser le next_posts_link() plusgénériqueet previous_posts_link() . Assurez-vous simplement de définir leparamètre $max_pagespour next_posts_links() sinon celane fonctionnerapas,et gardez à l'esprit que si,parmodification,vous utilisez cettepage comme statiquepage d'accueil,alors vous devez utiliser page,pas paged

MODIFIER 1

Utilisez les liensmentionnés ci-dessus comme suit

 next_posts_link( 'Older Entries', $loop->max_num_pages );
previous_posts_link( 'Newer Entries' );

MODIFIER 2

Jepense qu'il y a un légermalentendu. Essayez ce qui suit:

Dans vos arguments detype depublicationpersonnalisés où vousenregistrez votretype depublicationpersonnalisé,ajoutez ce qui suit,'has_archive' => true. Votrefonction devrait ressembler à ceci

 function custom_post_news() {
    register_post_type( 'news',
        array('labels' => array(
            'name' => __('News', 'post type general name'), /* This is the Title of the Group */
            'singular_name' => __('News', 'post type singular name'), /* This is the individual type */
            'add_new' => __('Add New', 'custom post type item'), /* The add new menu item */
            'add_new_item' => __('Add New'), /* Add New Display Title */
            'edit' => __( 'Edit' ), /* Edit Dialog */
            'edit_item' => __('Edit'), /* Edit Display Title */
            'new_item' => __('New '), /* New Display Title */
            'view_item' => __('View'), /* View Display Title */
            'search_items' => __('Search news'), /* Search Custom Type Title */
            'not_found' =>  __('Nothing found in the Database.'), /* This displays if there are no entries yet */
            'not_found_in_trash' => __('Nothing found in Trash'), /* This displays if there is nothing in the trash */
            'parent_item_colon' => ''
        ), /* end of arrays */
            'description' => __( 'This is the example custom post type' ), /* Custom Type Description */
            'public' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'show_ui' => true,
            'query_var' => true,
            'menu_position' => 2, /* this is what order you want it to appear in on the left hand side menu */
            'capability_type' => 'post',
            'hierarchical' => false,
            'rewrite' => array('slug' => 'news', 'with_front' => true ),
            'has_archive' => true,
            /* the next one is important, it tells what's enabled in the post editor */
            'supports' => array( 'title', 'editor', 'thumbnail')
        )
    );

}

Videz vospermaliens après cet ajout,puis visitez lapage d'accueil

Créez un archive-news.php. Cela devrait ressembler à ceci

 <?php
    while ( have_posts() ) : the_post();
?>

// Loop

<?php endwhile; ?>

<div id="pagination" class="clearfix">
    <?php posts_nav_link(); ?>
</div>

Ensuite,dans votrefunctions.php,utilisez pre_get_postspourmodifier la requêteprincipale sinécessaire.

 add_action( 'pre_get_posts', function ( $q ) {

    if( !is_admin() && $q->is_main_query() && $q->is_post_type_archive( 'news' ) ) {

        $q->set( 'posts_per_page', 2 );

    }

});

Supprimez lapage que vous avez créée dans leback-end. Tout devraitfonctionnerparfaitementmaintenant

posts_nav_link() won't work here

Useful for providing "paged" navigation of index, category and archive pages.

You will have to use the more generic next_posts_link() and previous_posts_link(). Just make sure to set the $max_pages parameter for next_posts_links() otherwise it will not work, and keep in mind, if by change, you are using this page as a static front page, then you should use page, not paged

EDIT 1

Use the above mentioned links as follows

next_posts_link( 'Older Entries', $loop->max_num_pages );
previous_posts_link( 'Newer Entries' );

EDIT 2

I think there is a slight misunderstanding. Try the following:

In your custom post type arguments where you register your custom post type, add the following, 'has_archive' => true. Your function should look like this

function custom_post_news() {
    register_post_type( 'news',
        array('labels' => array(
            'name' => __('News', 'post type general name'), /* This is the Title of the Group */
            'singular_name' => __('News', 'post type singular name'), /* This is the individual type */
            'add_new' => __('Add New', 'custom post type item'), /* The add new menu item */
            'add_new_item' => __('Add New'), /* Add New Display Title */
            'edit' => __( 'Edit' ), /* Edit Dialog */
            'edit_item' => __('Edit'), /* Edit Display Title */
            'new_item' => __('New '), /* New Display Title */
            'view_item' => __('View'), /* View Display Title */
            'search_items' => __('Search news'), /* Search Custom Type Title */
            'not_found' =>  __('Nothing found in the Database.'), /* This displays if there are no entries yet */
            'not_found_in_trash' => __('Nothing found in Trash'), /* This displays if there is nothing in the trash */
            'parent_item_colon' => ''
        ), /* end of arrays */
            'description' => __( 'This is the example custom post type' ), /* Custom Type Description */
            'public' => true,
            'publicly_queryable' => true,
            'exclude_from_search' => false,
            'show_ui' => true,
            'query_var' => true,
            'menu_position' => 2, /* this is what order you want it to appear in on the left hand side menu */
            'capability_type' => 'post',
            'hierarchical' => false,
            'rewrite' => array('slug' => 'news', 'with_front' => true ),
            'has_archive' => true,
            /* the next one is important, it tells what's enabled in the post editor */
            'supports' => array( 'title', 'editor', 'thumbnail')
        )
    );

}

Flush your permalinks after this addition and then visit the homepage

Create an archive-news.php. It should look like this

<?php
    while ( have_posts() ) : the_post();
?>

// Loop

<?php endwhile; ?>

<div id="pagination" class="clearfix">
    <?php posts_nav_link(); ?>
</div>

Next, in your functions.php, use pre_get_posts to alter the main query as needed.

add_action( 'pre_get_posts', function ( $q ) {

    if( !is_admin() && $q->is_main_query() && $q->is_post_type_archive( 'news' ) ) {

        $q->set( 'posts_per_page', 2 );

    }

});

Delete the page that you have created in the back end. Everything should work perfectly now
