安装时，我希望自动创建一个页面并将其设置为首页。我可以创建页面，但无法将其设置为首页。
下面是WP Install Defaults 安装后自动创建页面的代码：
function wp_install_defaults( $user_id ) {
global $wpdb, $wp_rewrite, $table_prefix;
$now = current_time( \'mysql\' );
$now_gmt = current_time( \'mysql\', 1 );
// First Page
$first_page = sprintf( __( "This is an example page.
Have fun!" ), admin_url() );
$wpdb->insert( $wpdb->posts, array(
\'post_author\' => $user_id,
\'post_date\' => $now,
\'post_date_gmt\' => $now_gmt,
\'post_content\' => $first_page,
\'comment_status\' => \'closed\',
\'post_title\' => __( \'Sample Page\' ),
\'post_name\' => __( \'sample-page\' ),
\'post_modified\' => $now,
\'post_modified_gmt\' => $now_gmt,
\'post_type\' => \'page\',
));
$wpdb->insert( $wpdb->postmeta, array( \'post_id\' => 2, \'meta_key\' => \'_wp_page_template\', \'meta_value\' => \'default\' ) );
}
我被困在这里，我不知道如何将页面设置为头版。
下面的代码取自2017年的主题，我不知道如何将其移植到WP Install Defaults
add_theme_support( \'starter-content\', array(
// ...
\'options\' => array(
\'show_on_front\' => \'page\',
\'page_on_front\' => \'{{sample-page}}\',
),
// ...
);

首先，你应该使用register_activation_hook, 当安装了wordpress插件时，这个钩子就会运行。
我也会把电话换成$wpdb 用于插入带有wp_insert_post.
wp_insert_post 成功时返回帖子ID，这可用于更新两者的选项page_on_front 和show_on_front.
function wp_install_defaults( $user_id ) {
$now = current_time( \'mysql\' );
$now_gmt = current_time( \'mysql\', 1 );
// First Page
$first_page = sprintf( __( "This is an example page.
Have fun!" ), admin_url() );
$query = new WP_Query( array(
\'pagename\' => \'sample-page\'
) );
if ( ! $query->have_posts() ) {
// Add the page using the data from the array above
$post_id = wp_insert_post(
array(
\'post_author\' => $user_id,
\'post_date\' => $now,
\'post_date_gmt\' => $now_gmt,
\'post_content\' => $first_page,
\'comment_status\' => \'closed\',
\'post_title\' => __( \'Sample Page\' ),
\'post_name\' => __( \'sample-page\' ),
\'post_modified\' => $now,
\'post_modified_gmt\' => $now_gmt,
\'post_type\' => \'page\',
)
);
if ( $post_id )
{
update_option( \'page_on_front\', $post_id );
update_option( \'show_on_front\', \'page\' );
}
}
}
register_activation_hook( __FILE__, \'wp_install_defaults\' );
