Debug Logger

安裝

This section describes how to install the plugin and get it working.

1. Upload the wp-debug-logger folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress

3. Enable debugging in your wp-config.php

   // in your wp-config.php
   define( ‘WP_DEBUG’, true );
   define( ‘WP_DEBUG_DISPLAY’, false );
   define( ‘WP_DEBUG_LOG’, true );
   define( ‘WP_DEBUG_MINIMUM_LEVEL’, ‘debug’ );

   // For good measure, this will hide errors from being displayed on-screen
   @ini_set(‘display_errors’, 0);

4. As you write your code, sprinkle in these Log methods.

Minimum Level

WP_DEBUG_MINIMUM_LEVEL is a new constant that determines the minimum severity level you wish to write to your wp-content/debug.log file. In your development environment, I recommend using debug so you can see all the errors being written. For your production environment, I’d recommend the error level, so you can capture all the significant problems. Here are the values to use: emergency, alert, critical, error, warning, notice, info, debug. Note: they’re all lowercase, as the value is case-sensitive.

Displaying Errors

In your development environment, you may choose to set WP_DEBUG_DISPLAY to true, so the error messages show in your browser. However, I strongly recommend that you do not change it, for your production environment. These settings can be placed anywhere above the line.
