## Snippets
### Create hook alter for user template suggestons
```php
/**
* Implements hook_theme_suggestions_user_alter().
*
* An array of alternate, more specific names for template files or theme
* functions for users.
*/
function training_theme_theme_suggestions_user_alter(&$suggestions, $vars, $hook) {
// Define the view mode.
$mode = $vars['elements']['#view_mode'];
// Create a theme hook suggestion which has the view mode name in it.
$suggestions[] = 'user__' . $mode;
}
```
### Fixing 403 Forbidden error in Pattern Lab
* Create an `.htaccess` file in the root of your theme with the following code: (Some have reported the file should be inside the `patternlab` directory. Try the theme's room first and recompile your theme).
```php
Require all granted
Order allow,deny
Allow from all
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://mariohernandez.gitbook.io/components/resources/resources.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
