作者:admin 发布时间:2018-10-28 20:45:41 浏览:970次
不知道从何开始慢慢的爱上了wordpress,湛江网站建设大部分利用wordpress作为内核进行二次开发,无论客户的要求有多高或多简单,都能很轻易的完成,也正是因为如此,才对wordpress更深入的了解,人接触的东西多了,容易忘,小超越也一样,因为每天接触的东西不止是编程,还有许许多多的东西,也许,随着时间的悄然流逝,有一天,再想回头来对wordpress进行深度开发,就忘记了很多常用的函数。 老师曾经说过,好记性不如烂笔头,是的,小超越100%的相信,所以才有了这篇文章!当然,以下的内容并不是小超越整理的,前辈们已经整理出来了,我们还何必再浪费时间去整理呢?是吧!
WP_Query 是 WordPress 的核心,它支持的参数非常灵活,也非常多,官方的文档也略嫌啰嗦,整理把所有的参数都整理了一遍,以后要使用 WP_Query 只要看这份文档就够了:
[cc lang="php"] $args = array( //////Author Parameters - Show posts associated with certain author. //http://codex.wordpress.org/Class_Reference/WP_Query#Author_Parameters 'author' => '1,2,3,', //(int) - use author id [use minus (-) to exclude authors by ID ex.

'tax_query' => array( //(array) - use taxonomy parameters (available with Version 3.1).

Specify posts to retrieve. ATTENTION If you use sticky posts, they will be included (prepended!) in the posts you retrieve whether you want it or not. To suppress this behaviour use ignore_sticky_posts 'post__not_in' => array(1,2,3), //(array) - use post ids. Specify post NOT to retrieve. //NOTE: you cannot combine 'post__in' and 'post__not_in' in the same query //////Password Parameters - Show content based on post and page parameters.

'post_type' => 'any', // - retrieves any type except revisions and types with 'exclude_from_search' set to true. //////Type & Status Parameters - Show posts associated with certain type or status. //http://codex.wordpress.org/Class_Reference/WP_Query#Status_Parameters 'post_status' => array( //(string / array) - use post status.

'post_status' => 'any', // - retrieves any status except those from post types with 'exclude_from_search' set to true. //////Pagination Parameters //http://codex.wordpress.org/Class_Reference/WP_Query#Pagination_Parameters 'posts_per_page' => 10, //(int) - number of post to show per page (available with Version 2.1). Use 'posts_per_page' => -1 to show all posts. //Note: if the query is in a feed, wordpress overwrites this parameter with the stored 'posts_per_rss' option. Treimpose the limit, try using the 'post_limits' filter, or filter 'pre_option_posts_per_rss' and return -1 'posts_per_archive_page' => 10, //(int) - number of posts to show per page - on archive pages only. Over-rides showposts anposts_per_page on pages where is_archive() or is_search() would be true 'nopaging' => false, //(bool) - show all posts or use pagination. Default value is 'false', use paging. 'paged' => get_query_var('paged'), //(int) - number of page. Show the posts that would normally show up just on page X when usinthe "Older Entries" link. //NOTE: Use get_query_var('page'); if you want your query to work in a Page template that you've set as your static front page. The query variable 'page' holds the pagenumber for a single paginated Post or Page that includes the lt;!--nextpage--gt; Quicktag in the post content. 'nopaging' => false, // (boolean) - show all posts or use pagination. Default value is 'false', use paging. 'posts_per_archive_page' => 10, // (int) - number of posts to show per page - on archive pages only. Over-rides posts_per_page and showposts on pages where is_archive() or is_search() would be true. 'offset' => 3, // (int) - number of post to displace or pass over. // Warning: Setting the offset parameter overrides/ignores the paged parameter and breaks pagination. for a workaround see: http://codex.wordpress.org/Making_Custom_Queries_using_Offset_and_Pagination // The 'offset' parameter is ignored when 'posts_per_page'=>-1 (show all posts) is used. 'paged' => get_query_var('paged'), //(int) - number of page. Show the posts that would normally show up just on page X when usinthe "Older Entries" link. //NOTE: This whole paging thing gets tricky. Some links to help you out: // http://codex.wordpress.org/Function_Reference/next_posts_link#Usage_when_querying_the_loop_with_WP_Query // http://codex.wordpress.org/Pagination#Troubleshooting_Broken_Pagination 'page' => get_query_var('page'), // (int) - number of page for a static front page. Show the posts that would normally show up just on page X of a Static Front Page. //NOTE: The query variable page holds the pagenumber for a single paginated Post or Page that includes the nextpage Quicktag in the post content. 'ignore_sticky_posts' => false, // (boolean) - ignore sticky posts or not (available with Version 3.1, replaced caller_get_posts parameter). Default value is 0 - don't ignore sticky posts.

EX: 'orderby' => 'menu_order title' //Possible Values: //'none' - No order (available with Version 2.8). //'ID' - Order by post id. Note the captialization. //'author' - Order by author. //'title' - Order by title. //'name' - Order by post name (post slug). //'date' - Order by date. //'modified' - Order by last modified date. //'parent' - Order by post/page parent id. //'rand' - Random order. //'comment_count' - Order by number of comments (available with Version 2.9). //'menu_order' - Order by Page Order.

Note alsthat the sorting will be alphabetical which is fine for strings (i.e. words), but can bunexpected for numbers (e.g. 1, 3, 34, 4, 56, 6, etc, rather than 1, 3, 4, 6, 34, 56 as yomight naturally expect). //'meta_value_num' - Order by numeric meta value (available with Version 2.8). Also notthat a 'meta_key=keyname' must also be present in the query. This value allows for numericasorting as noted above in 'meta_value'. //'title menu_order' - Order by both menu_order AND title at the same time.

Default value is '=' 'column' => 'post_date', //(string) - Column to query against. Default: 'post_date'. 'relation' => 'AND', //(string) - OR or AND, how the sub-arrays should be compared. Default: AND. ), ), //////Custom Field Parameters - Show posts associated with a certain custom field. //http://codex.wordpress.org/Class_Reference/WP_Query#Custom_Field_Parameters 'meta_key' => 'key', //(string) - Custom field key.
