Docker Compose: WORDPRESS_CONFIG_EXTRA
The Docker image for WordPress contains a property called “WORDPRESS_CONFIG_EXTRA”, this allows code to be passed directly to the wp-config.php file. This is great because you can fully customize your WordPress wp-config.php file.
Queryable Variable for Enabling Debug
My normal PHP code will not work:
|
1 2 3 |
if (isset($_GET['debug']) && $_GET['debug'] == 'debug') { define('WP_DEBUG', true); } |
The trick to getting this code to work is escaping the “$” in Docker. This can easily be done by using double “$$”.
|
1 2 3 |
if (isset($$_GET['debug']) && $$_GET['debug'] == 'debug') { define('WP_DEBUG', true); } |
Docker Compose File
This attribute can also be utilized in the Docker Compose file.
