我是开发wordpress插件的新手。我正在开发一个插件，每当插件被激活时，我都成功地创建了一个新页面，但我想向该页面添加一个自定义 php 模板文件。这意味着在激活时，我想使用自定义模板创建自定义页面。可以做到吗？
要创建一个新页面，我使用了以下代码，但在添加模板时找不到任何内容：
register_activation_hook(__FILE__,'my_plugin_install');
function my_plugin_install() {
global $wpdb;
$the_page_title = 'Custom Cart';
$the_page_name = 'cart';
delete_option("Custom Cart");
add_option("Custom Cart", $the_page_title, '', 'yes');
delete_option("cart");
add_option("cart", $the_page_name, '', 'yes');
delete_option("my_plugin_page_id");
add_option("my_plugin_page_id", '0', '', 'yes');
$the_page = get_page_by_title( $the_page_title );
if ( ! $the_page ) {
$_p = array();
$_p['post_title'] = $the_page_title;
$_p['post_content'] = "This text may be overridden by the plugin. You shouldn't edit it.";
$_p['post_status'] = 'publish';
$_p['post_type'] = 'page';
$_p['comment_status'] = 'closed';
$_p['ping_status'] = 'closed';
$_p['post_category'] = array(1);
$the_page_id = wp_insert_post( $_p );
}
else {
$the_page_id = $the_page->ID;
$the_page->post_status = 'publish';
$the_page_id = wp_update_post( $the_page );
}
delete_option( 'my_plugin_page_id' );
add_option( 'my_plugin_page_id', $the_page_id );
}
这是一种在WordPress中创建带有附加模板的页面的简单方法。为了创建一个新页面，我使用了以下代码：
register_activation_hook(__FILE__,'my_plugin_install');
function my_plugin_install() {
$the_slug = 'cart';
$args = array(
'name' => $the_slug,
'post_type' => 'page',
'post_status' => 'publish',
'numberposts' => 1
);
$my_posts = get_posts($args);
if(empty($my_posts)){
$my_post = array(
'post_title' => 'Custom Cart',
'post_content' => '',
'post_status' => 'publish',
'post_author' => 1,
'post_type' => 'page',
'post_name' => 'cart'
);
// Insert the post into the database
$post_id=wp_insert_post( $my_post );
update_post_meta( $post_id, '_wp_page_template', 'page-templates/cart.php' ); // optional to add page template
}
}
添加自定义页面模板： /theme/your-theme-name/page-templates/cart.php ：
<?php
/*
* Template Name: Custom Cart Page
*/
get_header(); ?>
HTML code here ..
<?php get_footer();?>
