Funkce get_posts, je jedna z hojn\u011b vyu\u017e\u00edvan\u00fdch funkc\u00ed, pro vytv\u00e1\u0159en\u00ed loop\u016f (smy\u010dek) s v\u00fdpisem \u010dl\u00e1nk\u016f. M\u016f\u017eete tak vypsat nap\u0159\u00edklad posledn\u00ed \u010dl\u00e1nky, nebo \u010dl\u00e1nky, dle zadan\u00fdch argument\u016f.<\/p>\n
Funkce get_posts se m\u016f\u017ee na prvn\u00ed pohled jevit jako podobn\u00e1 funkci get_pages, ale na rozd\u00edl od n\u00ed, nep\u0159istupuje p\u0159\u00edmo do datab\u00e1ze. Nam\u00edsto toho, vyu\u017e\u00edv\u00e1 WP_Query a ka\u017ed\u00fdm zavol\u00e1n\u00edm get_posts, tak vytvo\u0159\u00edte novou instanci objektu. D\u00edky tomu tak m\u016f\u017eete na str\u00e1nce vytvo\u0159it v\u00edce loop\u016f – v\u00fdpis\u016f \u010dl\u00e1nk\u016f, dle r\u016fzn\u00fdch parametr\u016f. Pokud tedy na hlavn\u00ed stran\u011b \u0161ablony vid\u00edte r\u016fzn\u00e9 v\u00fdpisy posledn\u00edch \u010dl\u00e1nk\u016f, \u010dl\u00e1nk\u016f od autora, nebo kategorie, m\u016f\u017eete toho dos\u00e1hnout pr\u00e1v\u011b pou\u017eit\u00edm get_posts. WP_Query pou\u017e\u00edv\u00e1 tak\u00e9 query_posts, ale nedoporu\u010duje se pou\u017e\u00edvat, pokud nechcete ovlivnit hlavn\u00ed loop na str\u00e1nce. Pokud chcete ovlivnit hlavn\u00ed v\u00fdpis, pou\u017eijte pro to hook pre_get_posts.<\/p>\n
