Get WordPress Post ID from Post title
提问by Aaron
I have an issue with a custom WordPress theme I'm developing. It's a bit convoluted, but essentially, what I need to do is get a Post Id by it's Post Title. In pseudo-code it would ideally be something like:
我正在开发的自定义 WordPress 主题有问题。这有点令人费解，但本质上，我需要做的是通过它的帖子标题获得一个帖子 ID。在伪代码中，它最好是这样的：
title = "foo";
post_id = get_post_id_where_title_is(title);
The title mentioned is a static reference not being pulled in from WordPress, it's already present on the page.
提到的标题是一个静态引用，不是从 WordPress 中提取的，它已经出现在页面上。
Thanks in advance.
提前致谢。

Just a quick note for anyone who stumbles across this:
get_page_by_title()can now handle any post type.
The $post_typeparameter has been added in WP 3.0.

function get_post_by_title($page_title, $output = OBJECT) {
global $wpdb;
$post = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type='post'", $page_title ));
if ( $post )
return get_post($post, $output);
return null;

Like Michal Mau mentioned:
就像 Michal Mau 提到的：
Use
用
$my_post = get_page_by_title( 'My Title', OBJECT, 'post' );
echo $my_post->post_content;
It's ( $page_title, $output, $post_type )to easily receive a post instead of a page.
这是( $page_title, $output, $post_type )为了轻松接收帖子而不是页面。

May this will help you more by creating function so that you need not to repeat the code
可能这会通过创建函数来帮助你更多，这样你就不需要重复代码了
function get_page_id_by_title($title)
{
$page = get_page_by_title($title);
return $page->ID;
}
$title = "your title";
get_page_id_by_title($title);

it is easy to get the post id from post title using wp query:
使用 wp 查询很容易从帖子标题中获取帖子 ID：
global $wpdb;
$rw = $wpdb->get_row( $wpdb->prepare("select * from "your post table name" where post_title='your variable name or your post title'"));
echo $rw->ID;

1) differ post_titleand post_namefrom each other. post_name maybe is the slug. post_title is the title of post.
1) post_title和post_name彼此不同。post_name 可能是蛞蝓。post_title 是帖子的标题。
2)
2)
$titlee = "yourtitle";
echo $id = $wpdb->get_var("SELECT ID FROM $GLOBALS['wpdb']->posts WHERE post_name = $titlee");

Another way to get the post and page ID, is to use a plugin..
获取帖子和页面 ID 的另一种方法是使用插件。
there is a plugin, that what it simply does, is just add a column to your all pages, all posts, all categories tables, and have a column title of ID...and right below, you will see all the page/post id listed in that column..
有一个插件，它的作用很简单，就是在你的所有页面、所有帖子、所有类别表中添加一列，并有一个 ID 的列标题......就在下面，你将看到所有页面/帖子该列中列出的 ID..
I think that should be very useful..
我觉得应该很有用。。
I use this plugin very frequently and it is very lightweight.
我经常使用这个插件，它非常轻巧。

No need to use any type of SQL querys or plugin, use Wordpress standard functions for this
无需使用任何类型的 SQL 查询或插件，为此使用 Wordpress 标准函数
$page = get_page_by_title( 'Home' );
$page_id = $page->ID;
