Debugging WordPress plugins on a live website

19. May 2016

Sometimes we need to debug a WordPress plugin, even though the website is live.

This would display the errors for anyone.

define('WP_DEBUG', true);

1	define('WP_DEBUG', true);

Gladly WordPress provides options to do this more subtle.

// Turns WordPress debugging on
define('WP_DEBUG', true);
 
// Tells WordPress to log everything to the /wp-content/debug.log file
define('WP_DEBUG_LOG', true);
 
// Doesn't force the PHP 'display_errors' variable to be on
define('WP_DEBUG_DISPLAY', false);
 
// Hides errors from being displayed on-screen
@ini_set('display_errors', 0);

// Turns WordPress debugging on

define('WP_DEBUG', true);

// Tells WordPress to log everything to the /wp-content/debug.log file

define('WP_DEBUG_LOG', true);

// Doesn't force the PHP 'display_errors' variable to be on

define('WP_DEBUG_DISPLAY', false);

// Hides errors from being displayed on-screen

@ini_set('display_errors', 0);

Enjoy coding …

I am a full-stack developer. My expertise include:

Server, Network and Hosting Environments
Data Modeling / Import / Export
Business Logic
API Layer / Action layer / MVC
User Interfaces
User Experience
Understand what the customer and the business needs

I love programming, design and know my way around server architecture as well. I would never feel complete, with one of these missing.

I have a broad range of interests, that’s why I constantly dive into new technologies and expand my knowledge where ever required. Technologies are evolving fast and I enjoy using the latest.

Apart from that, I am a peace loving guy who tries to have people around him that think the same. I truly believe in the principle: “If you help someone, someone will help you, when you need it."
