嗨@janoChen:
简单的回答:不。
接下来是什么功能的PHP代码wp_reset_query()
从/wp-includes/query.php
在WordPress v3.0.4以及功能随后被调用。您可以看到它主要是关于修改全局变量的。
使用时,new WP_Query($args)
您将把值的返回值分配给局部变量,因此,除非您做的事情太复杂以至于您不知道该问题的答案,否则就不需要调用wp_reset_query()
:
function wp_reset_query() {
unset($GLOBALS['wp_query']);
$GLOBALS['wp_query'] =& $GLOBALS['wp_the_query'];
wp_reset_postdata();
}
function wp_reset_postdata() {
global $wp_query;
if ( !empty($wp_query->post) ) {
$GLOBALS['post'] = $wp_query->post;
setup_postdata($wp_query->post);
}
}
function setup_postdata($post) {
global $id, $authordata, $day, $currentmonth, $page, $pages, $multipage, $more, $numpages;
$id = (int) $post->ID;
$authordata = get_userdata($post->post_author);
$day = mysql2date('d.m.y', $post->post_date, false);
$currentmonth = mysql2date('m', $post->post_date, false);
$numpages = 1;
$page = get_query_var('page');
if ( !$page )
$page = 1;
if ( is_single() || is_page() || is_feed() )
$more = 1;
$content = $post->post_content;
if ( strpos( $content, '<!--nextpage-->' ) ) {
if ( $page > 1 )
$more = 1;
$multipage = 1;
$content = str_replace("\n<!--nextpage-->\n", '<!--nextpage-->', $content);
$content = str_replace("\n<!--nextpage-->", '<!--nextpage-->', $content);
$content = str_replace("<!--nextpage-->\n", '<!--nextpage-->', $content);
$pages = explode('<!--nextpage-->', $content);
$numpages = count($pages);
} else {
$pages = array( $post->post_content );
$multipage = 0;
}
do_action_ref_array('the_post', array(&$post));
return true;
}
