WordPress开发中的get_post_custom()函数使用解析_PHP
同get_post_meta()一样,用于返回文章的自定义字段值得一个函数,只不过get_post_custom()函数使用起来更简单,如果在循环中使用你甚至不需要设置任何参数。
其实get_post_custom()函数的基础实现与get_post_meta()大同小异~
get_post_custom()使用
get_post_custom($postid);
只接受一个参数
$postid文章id;
实例演示
if (have_posts()) : while (have_posts()) : the_post(); var_dump(get_post_custom()); endwhile; endif;
输出的结果如下:(如果如下字段有设置的话)
array(4) { [“_edit_last”]=> array(1) { [0]=> string(1) “1” } [“_edit_lock”]=> array(1) { [0]=> string(12) “1342451729:1” } [“_thumbnail_id”]=> array(1) { [0]=> string(3) “228” } [“xzmeta”]=> array(2) { [0]=> string(3) “xz1” [1]=> string(3) “xz2” } }
get_post_custom_values和get_post_custom_keys
因为自定义字段分为,键值(keys) 和 自定义字段值(values),有些时候我们需要单独获取这两个值,所以 WordPress 中就派生出了get_post_custom_values和get_post_custom_keys两个函数,至于意义嘛,我还真没有发现出有多大意义,除了在批量删除自定义字段的时候有一定用除外,我还真没想出什么地方能用到,也许在一个浩瀚的 CMS主题中会有着非常剧组轻重的意义。
之前写到了get_post_custom函数和get_post_meta函数,私下里想着,反正自定义字段的相关函数也不多,所以就顺手整理了一下,索性把自定义字段相关的函数都写一下,当然不包括函数的一些基础实现代码。
get_post_custom_values用于获取当前文章的指定自定义字段的值,并以数组形式返回。
while (have_posts()) : the_post(); var_dump(get_post_custom_values(‘xzmeta')); endwhile; endif;
大致会返回如下结果
(如果自定义字段有设置)
array(2) { [0]=> string(3) “xz1” [1]=> string(3) “xz2” }
get_post_custom_keys用于获取当前文章所有的自定义字段的键值。
if (have_posts()) : while (have_posts()) : the_post(); var_dump(get_post_custom_keys()); endwhile; endif;
大致会获得 以下结果:
(如果自定义字段有设置)
array(4) { [0]=> string(10) “_edit_last” [1]=> string(10) “_edit_lock” [2]=> string(13) “_thumbnail_id” [3]=> string(6) “xzmeta” }
