What is a template? By default, WordPress uses page.php in the theme directory as a template to display pages, but sometimes we need different templates to display pages, such as login, registration and submission pages, etc. These pages are different from ordinary pages. At this time, WordPress provides page templates so that developers can customize the appearance and even functions of WordPress pages.
Matching of page template php files
WordPress records the template used by the page through a custom column. The custom column name: _wp_page_template, the value is the file name of the template:
If it is the default template page.php, then The value of _wp_page_template is: default. If it is the default template from beginning to end, WordPress will not add this custom column
If it is a custom page template in the theme root directory, then the value of _wp_page_template is the file name, such as: page-login.php
If It is a page template under the theme subdirectory, then the value of _wp_page_template contains the path, such as: templates/page-login.php
Because the name of this custom column starts with an underscore, it is a hidden custom column, so you This field cannot be seen in the custom column on the page edit page.
Get the page ID through the page template
I created a new login page template, named login.php, and there is already a page using this template in the background, then I can use the following function to get the login.php Template page id:
function get_page_id_from_template($template) { global $wpdb; // 多个页面使用同一个模板我就没辙了 $page_id = $wpdb->get_var($wpdb->prepare("SELECT `post_id` FROM `$wpdb->postmeta`, `$wpdb->posts` WHERE `post_id` = `ID` AND `post_status` = 'publish' AND `meta_key` = '_wp_page_template' AND `meta_value` = %s LIMIT 1;", $template)); return $page_id; }
Many people may ask, what are you doing to get the page id? Isn’t it possible to get the link to the login page through the id:
<a href="<?php%20%0Aecho%20get_permalink(get_page_id_from_template('login.php'))%0A?>>%E7%99%BB%E5%BD%95</a>%0A
