几天前我发了一个帖子“How to make a fake WordPress post for each user separately”
我设法使用this资源制作假帖子。除非我尝试使用自定义字段选项执行相同操作,否则一切都很好。我正在使用的主题在wp_postmeta
中有一个单独的自定义字段,其中嵌入的视频包含在单独的<div>
中。
这是我尝试用于设置自定义字段选项的代码。
function kpg_f_content() {
global $wp_query;
$post = new stdClass();
$post -> ID = 1;
$post -> post_category = array('uncategorized');
//Add some categories. an array()???
$post -> post_content = 'hey here we are a real post';
//The full text of the post.
$post -> post_excerpt = 'hey here we are a real post';
//For all your post excerpt needs.
$post -> post_status = 'publish';
//Set the status of the new post.
$post -> post_title = 'Fake Title 1';
//The title of your post.
$post -> post_type = 'post';
//Sometimes you might want to post a page.
$post -> post_date = '[ 2013-12-19 5:34:3 ]';
//The time post was made.
$post -> post_date_gmt = '[ 2013-12-19 5:34:3 ]';
//The time post was made, in GMT.
$vid = new stdClass();
$vid -> meta_key = 'video_url';
$vid -> meta_value = 'http://www.youtube.com/watch?v=ucivXRBrP_0';
$vid1 = new stdClass();
$vid1 -> meta_key = '_oembed_576540b29025537e24e5bcdcae946a46';
$vid1 -> meta_value = '<iframe width="500" height="281" src="http://www.youtube.com/embed/ucivXRBrP_0?feature=oembed" frameborder="0" allowfullscreen></iframe>';
$wp_query -> queried_object = $post;
$wp_query -> post = $post;
$wp_query -> found_posts = 2;
$wp_query -> post_count = 2;
$wp_query -> max_num_pages = 2;
$wp_query -> is_single = 1;
$wp_query -> is_404 = false;
$wp_query -> is_posts_page = 0;
$wp_query -> posts = $post;
$wp_query -> page = false;
$wp_query -> is_post = true;
$wp_query -> page = false;
$wp_query -> meta_query = array($vid, $vid1);
}
add_action('wp', 'kpg_f_content');
我即兴创作的部分是$wp_query->meta_query=array($vid,$vid1);
,但它没有帮助,因为它预期就好像即使设置这两个选项也不会设置post_id
并且主题找不到哪个帖子是选项。
伙计们有什么想法我怎么能这样做?

$wp_query->meta_query
属性据我了解$wp_query
对象,您无法将结果数据直接添加到$wp_query->meta_query
属性以伪造自定义帖子元数据。
它仅用于构建元查询,且类型为WP_Meta_Query
。
如果您查看WP_Query
课程的source code,您会看到以下这些专栏:
// Parse meta query
$this->meta_query = new WP_Meta_Query();
$this->meta_query->parse_query_vars( $q );
以下是WP_Meta_Query
类的说明。
您可以尝试使用get_post_metadata
过滤器,或一般get_x_metadata
x
{post, comment, user}
。
以下是一个例子:
function custom_get_post_metadata( $meta_value, $object_id, $meta_key, $single )
{
// Change the meta value of the meta key 'video_url'
// for post id 1 when 'single' is TRUE
if( 1 === $object_id
&& TRUE === $single
&& 'video_url' === $meta_key )
{
$meta_value = 'http://www.youtube.com/watch?v=ucivXRBrP_0';
}
return $meta_value;
}
add_filter( 'get_post_metadata', 'custom_get_post_metadata', 99, 4 );
使用时 伪 video_url
元键的值:
echo get_post_meta( get_the_ID(), 'video_url' , TRUE );
在你的主题中。
类似于_oembed_576540b29025537e24e5bcdcae946a46
元键。

就我所知,meta_query实际上是一个数组,而不是一个对象,所以,试试:
$vid = array('meta_key' => 'video_url', 'meta_value' => 'http://www.youtube.com/watch?v=ucivXRBrP_0');
$vid1 = array('meta_key' = '_oembed_576540b29025537e24e5bcdcae946a46', 'meta_value' => '<iframe width="500" height="281" src="http://www.youtube.com/embed/ucivXRBrP_0?feature=oembed" frameborder="0" allowfullscreen></iframe>');
