get wordpress post by post title
提问by user2710234
i am using this code to show wordpress posts in an external website:
我正在使用此代码在外部网站中显示 wordpress 帖子：
<?php
require('wp_blog/wp-blog-header.php');
if($_GET["p"] > '') { ?>
<?php query_posts('p='.$_GET["p"].''); ?>
<?php while (have_posts()) : the_post(); ?>
<h4><?php the_title(); ?></h4>
<?php the_content(); ?>
<?php endwhile; ?>
<?php } else { ?>
<?php
$posts = get_posts('numberposts=10&order=ASC&orderby=post_title');
foreach ($posts as $post) : setup_postdata( $post ); ?>
<?php the_date(); echo "<br />"; ?>
<?php the_title(); ?>
<?php the_excerpt(); ?>
<?php endforeach; ?>
<?php } ?>
rather than selecting the post based on the ID, how can i make it select the post based on the post title?
不是根据 ID 选择帖子，我怎样才能让它根据帖子标题选择帖子？

You can use get_page_by_title()to fetch post by title.Like this:
您可以使用 get_page_by_title()按标题获取帖子。像这样：
$page = get_page_by_title('About', OBJECT, 'post');
echo $page->ID

$postid = $wpdb->get_var( "SELECT ID FROM $wpdb->posts WHERE post_title = '" . $posttitle . "'" );
echo $postid;

try this
尝试这个
$post_title = 'Contact';
$post_id = get_page_by_title($post_title, OBJECT, 'your_post_type_name');
echo $post_id->ID; // your id

Add Function Like this
像这样添加功能
function get_page_by_post_name($post_name, $output = OBJECT, $post_type = 'post' ){
global $wpdb;
$page = $wpdb->get_var( $wpdb->prepare( "SELECT ID FROM $wpdb->posts WHERE post_title = %s AND post_type= %s", $post_name, $post_type ) );
if ( $page ) return get_post( $page, $output );
return null;
}
add_action('init','get_page_by_post_name');
And run like that:
并像这样运行：
$page = get_page_by_post_name('hello-world', OBJECT, 'post');
echo $page->ID;
