/**
|
|
* This abstract class and it's concrete classes implement defaults and value validation for
|
|
* all WPSEO options and subkeys within options.
|
|
*
|
|
* Some guidelines:
|
|
* [Retrieving options]
|
|
* - Use the normal get_option() to retrieve an option. You will receive a complete array for the option.
|
|
* Any subkeys which were not set, will have their default values in place.
|
|
* - In other words, you will normally not have to check whether a subkey isset() as they will *always* be set.
|
|
* They will also *always* be of the correct variable type.
|
|
* The only exception to this are the options with variable option names based on post_type or taxonomy
|
|
* as those will not always be available before the taxonomy/post_type is registered.
|
|
* (they will be available if a value was set, they won't be if it wasn't as the class won't know
|
|
* that a default needs to be injected).
|
|
*
|
|
* [Updating/Adding options]
|
|
* - For multisite site_options, please use the WPSEO_Options::update_site_option() method.
|
|
* - For normal options, use the normal add/update_option() functions. As long a the classes here
|
|
* are instantiated, validation for all options and their subkeys will be automatic.
|
|
* - On (succesfull) update of a couple of options, certain related actions will be run automatically.
|
|
* Some examples:
|
|
* - on change of wpseo[yoast_tracking], the cron schedule will be adjusted accordingly
|
|
* - on change of wpseo and wpseo_title, some caches will be cleared
|
|
*
|
|
* [Important information about add/updating/changing these classes]
|
|
* - Make sure that option array key names are unique across options. The WPSEO_Options::get_all()
|
|
* method merges most options together. If any of them have non-unique names, even if they
|
|
* are in a different option, they *will* overwrite each other.
|
|
* - When you add a new array key in an option: make sure you add proper defaults and add the key
|
|
* to the validation routine in the proper place or add a new validation case.
|
|
* You don't need to do any upgrading as any option returned will always be merged with the
|
|
* defaults, so new options will automatically be available.
|
|
* If the default value is a string which need translating, add this to the concrete class
|
|
* translate_defaults() method.
|
|
* - When you remove an array key from an option: if it's important that the option is really removed,
|
|
* add the WPSEO_Option::clean_up( $option_name ) method to the upgrade run.
|
|
* This will re-save the option and automatically remove the array key no longer in existance.
|
|
* - When you rename a sub-option: add it to the clean_option() routine and run that in the upgrade run.
|
|
* - When you change the default for an option sub-key, make sure you verify that the validation routine will
|
|
* still work the way it should.
|
|
* Example: changing a default from '' (empty string) to 'text' with a validation routine with tests
|
|
* for an empty string will prevent a user from saving an empty string as the real value. So the
|
|
* test for '' with the validation routine would have to be removed in that case.
|
|
* - If an option needs specific actions different from defined in this abstract class, you can just overrule
|
|
* a method by defining it in the concrete class.
|
|
*
|
|
* @todo [JRF => testers] Double check that validation will not cause errors when called
|
|
* from upgrade routine (some of the WP functions may not yet be available).
