| ResourceLoaderGetConfigVars | |
|---|---|
| Available from version 1.17.0 Called right before ResourceLoaderStartUpModule::getConfig returns, to set static (not request-specific) configuration variables. Can not depend on current page, current user or current request; see below. | |
| Define function: | public static function onResourceLoaderGetConfigVars( array &$vars, string $skin, Config $config ) { ... }
|
| Attach hook: | In extension.json:
{
"Hooks": {
"ResourceLoaderGetConfigVars": "MediaWiki\\Extension\\MyExtension\\Hooks::onResourceLoaderGetConfigVars"
}
}
|
| Called from: | File(s): resourceloader/ResourceLoaderStartUpModule.php |
| Interface: | ResourceLoaderGetConfigVarsHook.php |
For more information about attaching hooks, see Manual:Hooks.
For examples of extensions using this hook, see Category:ResourceLoaderGetConfigVars extensions/en.
Details
ResourceLoaderStartUpModule::getConfig() runs this hook. Use it to export static configuration variables to JavaScript. Values that depend on the current page, user or request state must be added through MakeGlobalVariablesScript instead.
- &$vars - Array of variables to be added into the output of the startup module.
- $skin - (introduced in 1.32) Current skin name to restrict config variables to a certain skin (if needed)
- $config - (introduced in 1.34)
Example
Register the configuration variables from the hook:
class VisualEditorHooks {
public static function onResourceLoaderGetConfigVars( array &$vars, string $skin, Config $config ) {
$vars['wgVisualEditor'] = [
'disableForAnons' => $config->get( 'VisualEditorDisableForAnons' ),
'enableExperimentalCode' => $config->get( 'VisualEditorEnableExperimentalCode' ),
];
return true;
}
}
Retrieve them using mw.config, like:
conf = mw.config.get( 'wgVisualEditor' );
if ( conf.disableForAnons ) {
// Do stuff
}
