Same name and namespace in other branches
- 8 core/lib/Drupal/Core/Url.php \Drupal\Core\Url::fromUserInput()
- 9 core/lib/Drupal/Core/Url.php \Drupal\Core\Url::fromUserInput()
Creates a Url object for a relative URI reference submitted by user input.
Use this method to create a URL for user-entered paths that may or may not correspond to a valid Drupal route.
Parameters
string $user_input: User input for a link or path. The first character must be one of the following characters:
- '/': A path within the current site. This path might be to a Drupal route (e.g., '/admin'), to a file (e.g., '/README.txt'), or to something processed by a non-Drupal script (e.g., '/not/a/drupal/page'). If the path matches a Drupal route, then the URL generation will include Drupal's path processors (e.g., language-prefixing and aliasing). Otherwise, the URL generation will just append the passed-in path to Drupal's base path.
- '?': A query string for the current page or resource.
- '#': A fragment (jump-link) on the current page or resource.
This helps reduce ambiguity for user-entered links and paths, and supports user interfaces where users may normally use auto-completion to search for existing resources, but also may type one of these characters to link to (e.g.) a specific path on the site. (With regard to the URI specification, the user input is treated as a relative URI reference where the relative part is of type path-abempty.)
array $options: (optional) An array of options. See Url::fromUri() for details.
Return value
static A new Url object based on user input.
Throws
\InvalidArgumentException Thrown when the user input does not begin with one of the following characters: '/', '?', or '#'.
