Generellt sett, n\u00e4r jag arbetar med anpassad posttyppaginering, g\u00f6rs det genom att skriva en anpassad fr\u00e5ga med WP_Query<\/a> och sedan anropa wp_reset_postdata()<\/a> i slutet av The Loop<\/a>.<\/p>\n

Jag tror fortfarande att detta har sin plats, men det finns en enklare l\u00f6sning som du kanske kan implementera med hj\u00e4lp av en specifik krok som WordPress tillhandah\u00e5ller.<\/p>\n

Specifikt pratar jag om pre_get_posts-<\/a> kroken. I kodreferensen kan du se att detta definieras som:<\/p>\n

\n

Utl\u00f6ses efter att fr\u00e5gevariabelobjektet har skapats, men innan den faktiska fr\u00e5gan k\u00f6rs.<\/p>\n<\/blockquote>\n

Och eftersom fr\u00e5gan inneh\u00e5ller mycket information kan vi g\u00e5 vidare och anv\u00e4nda den f\u00f6r att avg\u00f6ra om vi vill modifiera de n\u00f6dv\u00e4ndiga argumenten f\u00f6r att hantera sidnumrering.<\/p>\n

Med detta menar jag att vi m\u00e5ste titta p\u00e5 egenskapen post_type<\/strong> och posts_per_page-<\/strong> v\u00e4rdet. F\u00f6r att g\u00f6ra detta kan du implementera det p\u00e5 f\u00f6ljande s\u00e4tt<\/a> :<\/p>\n

<?php\n\nuse WP_Query;\n\nadd_action('pre_get_posts', __NAMESPACE__. 'customPostTypePagination');\n\/**\n * If we're on the 'acme-post-type' page, then adjusts pagination so there are only two posts per page. This will \n * affect pagination so we can use built-in pagination links to easily page through the content.\n *\n * @param WP_Query the instance of the query object that contains information to populate the template.\n *\n * @return WP_Query an unmodified version of the query object or a modified version if we're on the acme post-type.\n *\/\nfunction customPostTypePagination(WP_Query $query)\n{\n  if (isset($query->query['post_type']) && 'acme-post-type' == $query->query['post_type']) {\n    $query->set('posts_per_page', 2);\n  }\n}<\/code><\/pre>\n
Koden ovan \u00e4r inte objektorienterad (om det vore s\u00e5 skulle jag st\u00e4lla in en prenumerant och en klass som ansvarar f\u00f6r att hantera logiken i funktionen), men du kan se hur du st\u00e4ller in den i sin mest grundl\u00e4ggande form.<\/p>\n
S\u00e5 om du arbetar med anpassad posttyp paginering och inte vill ta itu med de olika aspekterna av att st\u00e4lla in en anpassad fr\u00e5ga, kan detta l\u00f6sa ditt problem.<\/p>\n
