wp-configr

A Python package for reading and writing configuration values in a WordPress wp-config.php file.

Overview

A default wp-config.php might look like this:

<?php
define( 'DB_NAME', 'database_name_here' );

wpconfigr will help you update the file to:

<?php
define( 'SOMETHING_ENTIRELY_NEW', 'garnet' );
define( 'DB_NAME', 'my_blog' );

wpconfigr exposes two functions:

• set(key, value) will update a property of name key if it exists, otherwise will create it.
• get(key) will return the value of the property of name key, or None if it doesn't exist.

Installation

pip install wpconfigr

Command-line usage

Writing values to wp-config.php

Named parameters:

• --filename: Full path and filename of the wp-config.php file.
• --key: Name of the property to create/update.
• --value: String value to set.
• --set-true: Set the value to boolean true.
• --set-false: Set the value to boolean false.
• --log-level: (Optional) Log level.

python -m wpconfigr --filename  /www/wp-config.php \
                    --key       DB_NAME \
                    --value     my_blog \
                    --log-level info

Reading values from wp-config.php

As above, but do not specify a value (via the --value, --set-true or --set-false arguments).

python -m wpconfigr --filename /www/wp-config.php \
                    --key      DB_NAME

Code usage

To update a string holding wp-config.php content:

from wpconfigr import WpConfigString

config = WpConfigString(config_string)
config.set('DB_NAME', 'my_blog')
updated_config_string = config.content

To directly update a wp-config.php file:

from wpconfigr import WpConfigFile

config = WpConfigFile(filename)
config.set('DB_NAME', 'my_blog')
# File is updated immediately after each property update.

To read a property value:

db_name = config.get('DB_NAME')
