How can errors, specific to a given plugin, be logged to an
error_log file contained within the plugin root folder itself?
- Syntax errors
- Database errors
- Compatibility errors
- PHP fatal errors
- Ajax request errors
Similar to the
/wp-content/debug.log file enable when
WP_DEBUG_LOG is defined as
true in the
wp-config.php file (albeit specifically for plugins with its concerns separated from any other general error unrelated to the plugin itself).
Debugging Plugins section in the official documentation of the Codex refers to using 3rd party plugins to debug 3rd party plugins.
Don’t Develop Without Debuggingby Smashing Magazine refers to site-wide general debugging.
Plugin Handbook appears to layout no specific guidelines.
