# persistent configuration

Your plugin may need to store some configuration information. In fact, Blessing Skin itself also has a lot of configuration information and options, which are all stored in the optionstable in the database.

It is not recommended that you read the configuration directly by reading the data table, but you should use the OptionFacade or optionauxiliary function provided by Blessing Skin and Blessing Skin is also used internally.

# application

Suppose your plugin needs to get information from an external URL, and this URL can be modified by the user to switch between different sources. We can set a configuration item called "data_source", then we can get or set this configuration item through OptionFacade or optionhelper function.

When setting a configuration item, if the configuration item does not exist, it will be added automatically without manually modifying the database.

# Use Facade

You can use the OptionFacade to manipulate your configuration items.

use Option ; 

// Get the value of `data_source` 
Option ::get( ' data_source ' ) ; 

// It is also allowed to return the default value, if the configuration item does not exist or the value is empty 
Option::get( ' data_source ' , 'http://xxx/' ) ; 

// update configuration 
itemOption ::set( 'data_source' , 'http://xxx/' ) ;

# Use helper functions

Auxiliary functions are available globally and do not need to be imported like Facade before use, so it is easier to use.

For detailed usage, please read option Functions and option_localized function .
