_deprecated_function()

💡 云策文档标注

概述

_deprecated_function() 是 WordPress 中用于标记函数已弃用的核心函数，当被调用时会触发通知，帮助开发者迁移到新函数。它主要用于在 WP_DEBUG 启用时生成用户错误，并提供了钩子用于跟踪调用来源。

关键要点

函数作用：标记函数为弃用状态，并在使用时通过触发错误或通知来提醒开发者。
触发条件：当 WP_DEBUG 为 true 且 deprecated_function_trigger_error 过滤器返回 true 时，会生成 E_USER_DEPRECATED 错误。
参数说明：接受三个参数：$function_name（被调用的函数名）、$version（弃用该函数的 WordPress 版本）、$replacement（可选，替代函数名）。
钩子支持：提供 deprecated_function_run 动作钩子，用于在弃用函数被调用时执行自定义逻辑；deprecated_function_trigger_error 过滤器钩子，用于控制是否触发错误。
使用场景：应在所有弃用函数中调用此函数，以确保向后兼容性和平滑迁移。

代码示例

function old_get_featured_image( $post_id ) {
    _deprecated_function( __FUNCTION__, '2.0.0', 'get_featured_image_url' );
    return get_featured_image_url( $post_id );
}

注意事项

从 WordPress 5.4.0 开始，错误类型从 E_USER_NOTICE 更改为 E_USER_DEPRECATED，提高了错误的严重性。
此函数自 WordPress 2.5.0 引入，是处理函数弃用的标准方法。

Here’s an example showing how to deprecate an old function old_get_featured_image in favor of a new function get_featured_image_url

/**
 * Retrieves the featured image URL (deprecated).
 *
 * @deprecated 2.0.0 Use get_featured_image_url() instead.
 *
 * @param int $post_id The post ID.
 * @return string|false The featured image URL or false if none.
 */
function old_get_featured_image( $post_id ) {
    // Trigger a deprecation notice
    _deprecated_function( __FUNCTION__, '2.0.0', 'get_featured_image_url' );

    // Call the replacement function so old code still works
    return get_featured_image_url( $post_id );
}

/**
 * Replacement function for retrieving the featured image URL.
 *
 * @param int $post_id The post ID.
 * @return string|false The featured image URL or false if none.
 */
function get_featured_image_url( $post_id ) {
    return get_the_post_thumbnail_url( $post_id );
}
