最近,Wordpress在Trac中添加了您可以使用以下标题获取帖子的帖子:
get_page_by_title
而不是直接查询数据库。如果我想获得标题为“我的农场”的帖子,我将如何更改参数以便搜索帖子(或帖子类型?):
$ page_title ='森林中的乔伊';
'character'是一种帖子类型。但不知道如何工作。我假设默认的回报是id,即$ post-> ID。如果我使用帖子类型,不确定相同的是什么。
感谢任何人对此的帮助

我写了a function(在错误报告中链接),它正是这样做的:
/**
* Retrieves a post/page/custom-type/taxonomy ID by its title.
*
* Returns only the first result. If you search for a post title
* that you have used more than once, restrict the type.
* Or don’t use this function. :)
* Simple usage:
* $page_start_id = id_by_title('Start');
*
* To get the ID of a taxonomy (category, tag, custom) set $tax
* to the name of this taxonomy.
* Example:
* $cat_css_id = id_by_title('CSS', 0, 'category');
*
* The result is cached internally to save db queries.
*
* @param string $title
* @param string $type Restrict the post type.
* @param string|bool $tax Taxonomy to search for.
* @return int ID or -1 on failure
*/
function id_by_title($title, $type = 'any', $tax = FALSE)
{
static $cache = array ();
$title = mysql_real_escape_string( trim($title, '"\'') );
// Unique index for the cache.
$index = "$title-$type-" . ( $tax ? $tax : 0 );
if ( isset ( $cache[$index] ) )
{
return $cache[$index];
}
if ( $tax )
{
$taxonomy = get_term_by('name', $title, $tax);
$cache[$index] = $taxonomy ? $taxonomy->term_id : -1;
return $cache[$index];
}
$type_sql = 'any' == $type
? ''
: "AND post_type = '"
. mysql_real_escape_string($type) . "'";
global $wpdb;
$query = "SELECT ID FROM $wpdb->posts
WHERE (
post_status = 'publish'
AND post_title = '$title'
$type_sql
)
LIMIT 1";
$result = $wpdb->get_results($query);
$cache[$index] = empty ( $result ) ? -1 : (int) $result[0]->ID;
return $cache[$index];
}

由于我点击此页面,其他人也可能。
get_page_by_title()
还会处理帖子和自定义帖子类型。
请注意,即使帖子被删除,它也会获得数据库中的第一个帖子/页面项目。
样品:
$post = get_page_by_title('sample-post','post');
echo $post->ID
