wp_validate_site_data()
云策文档标注
概述
wp_validate_site_data() 函数用于在将站点数据插入或更新到数据库前进行验证。它检查必需字段是否为空、日期是否有效,并确保站点域、路径和网络ID的唯一性。
关键要点
- 验证站点数据,包括域名、路径、网络ID和日期字段(注册日期和最后更新日期)。
- 使用 WP_Error 对象收集验证错误,通过引用传递。
- 对于新站点或更改的域/路径/网络ID,调用 domain_exists() 检查唯一性。
- 支持可选参数 $old_site,用于更新现有站点时的比较。
代码示例
function wp_validate_site_data( $errors, $data, $old_site = null ) {
// A domain must always be present.
if ( empty( $data['domain'] ) ) {
$errors->add( 'site_empty_domain', __( 'Site domain must not be empty.' ) );
}
// A path must always be present.
if ( empty( $data['path'] ) ) {
$errors->add( 'site_empty_path', __( 'Site path must not be empty.' ) );
}
// A network ID must always be present.
if ( empty( $data['network_id'] ) ) {
$errors->add( 'site_empty_network_id', __( 'Site network ID must be provided.' ) );
}
// Both registration and last updated dates must always be present and valid.
$date_fields = array( 'registered', 'last_updated' );
foreach ( $date_fields as $date_field ) {
if ( empty( $data[ $date_field ] ) ) {
$errors->add( 'site_empty_' . $date_field, __( 'Both registration and last updated dates must be provided.' ) );
break;
}
// Allow '0000-00-00 00:00:00', although it be stripped out at this point.
if ( '0000-00-00 00:00:00' !== $data[ $date_field ] ) {
$month = substr( $data[ $date_field ], 5, 2 );
$day = substr( $data[ $date_field ], 8, 2 );
$year = substr( $data[ $date_field ], 0, 4 );
$valid_date = wp_checkdate( $month, $day, $year, $data[ $date_field ] );
if ( ! $valid_date ) {
$errors->add( 'site_invalid_' . $date_field, __( 'Both registration and last updated dates must be valid dates.' ) );
break;
}
}
}
if ( ! empty( $errors->errors ) ) {
return;
}
// If a new site, or domain/path/network ID have changed, ensure uniqueness.
if ( ! $old_site
|| $data['domain'] !== $old_site->domain
|| $data['path'] !== $old_site->path
|| $data['network_id'] !== $old_site->network_id
) {
if ( domain_exists( $data['domain'], $data['path'], $data['network_id'] ) ) {
$errors->add( 'site_taken', __( 'Sorry, that site already exists!' ) );
}
}
}注意事项
- 验证失败时,错误信息通过 WP_Error 对象返回,不会抛出异常。
- 日期字段允许 '0000-00-00 00:00:00' 作为特殊值,但通常会被剥离。
- 函数在 WordPress 5.1.0 版本中引入。
