问题描述

如何从WordPress插件编写调试消息?

How can I write debug messages from my WordPress plugin?

在WordPress中进行调试 描述了如何我可以启用 wp-content/debug.log 文件.但是我该怎么写呢?是否有诸如 wp_log($ msg)之类的日志记录方法?我没有找到.

Debugging in WordPress describes how can I enable the wp-content/debug.log file. But how can I write to it? Is there any logging method like wp_log($msg) or something? I didn't find such.

推荐答案

如果 WP_DEBUG_LOG 设置为true，则error_log-INI设置已设置:

If WP_DEBUG_LOG is set to true, the error_log-INI setting is set:

ini_set( 'error_log', WP_CONTENT_DIR . '/debug.log' );

要写入该文件，可以使用 error_log -function :

To write to that file, you can use the error_log-function:

error_log("This message is written to the log file");

此功能不是特定于WordPress的，可以在任何PHP脚本中使用.

This function is not specific to WordPress and can be used in any PHP script.
