|
* Returns the URL to the page with $options
|
|
|
|
|
|
*
|
|
|
|
|
|
* You can specify an `$options` argument to this method with any of the following:
|
|
|
|
|
|
*
|
|
|
|
|
|
* - `pageNum` (int|string|bool): Specify pagination number, "+" for next pagination, "-" for previous pagination, or true for current.
|
|
|
|
|
|
* - `urlSegmentStr` (string|bool): Specify a URL segment string to append, or true (3.0.155+) for current.
|
|
|
|
|
|
* - `urlSegments` (array|bool): Specify regular array of URL segments to append (may be used instead of urlSegmentStr).
|
|
|
|
|
|
* Specify boolean true for current URL segments (3.0.155+).
|
|
|
|
|
|
* Specify associative array (in 3.0.155+) to make both keys and values part of the URL segment string.
|
|
|
|
|
|
* - `data` (array): Array of key=value variables to form a query string.
|
|
|
|
|
|
* - `http` (bool): Specify true to make URL include scheme and hostname (default=false).
|
|
|
|
|
|
* - `scheme` (string): Like the http option, makes URL include scheme and hostname, but you specify scheme with this, i.e. 'https' (3.0.178+)
|
|
|
|
|
|
* - `host` (string): Hostname to force use of, i.e. 'world.com' or 'hello.world.com'. The 'http' option is implied when host specified. (3.0.178+)
|
|
|
|
|
|
* - `language` (Language): Specify Language object to return URL in that Language.
|
|
|
|
|
|
*
|
|
|
|
|
|
* You can also specify any of the following for `$options` as shortcuts:
|
|
|
|
|
|
*
|
|
|
|
|
|
* - If you specify an `int` for options it is assumed to be the `pageNum` option.
|
|
|
|
|
|
* - If you specify `+` or `-` for options it is assumed to be the `pageNum` “next/previous pagination” option.
|
|
|
|
|
|
* - If you specify any other `string` for options it is assumed to be the `urlSegmentStr` option.
|
|
|
|
|
|
* - If you specify a `boolean` (true) for options it is assumed to be the `http` option.
|
|
|
|
|
|
*
|
|
|
|
|
|
* Please also note regarding `$options`:
|
|
|
|
|
|
*
|
|
|
|
|
|
* - This method honors template slash settings for page, URL segments and page numbers.
|
|
|
|
|
|
* - Any passed in URL segments are automatically sanitized with `Sanitizer::pageNameUTF8()`.
|
|
|
|
|
|
* - If using the `pageNum` or URL segment options please also make sure these are enabled on the page’s template.
|
|
|
|
|
|
* - The query string generated by any `data` variables is entity encoded when output formatting is on.
|
|
|
|
|
|
* - The `language` option requires that the `LanguageSupportPageNames` module is installed.
|
|
|
|
|
|
* - The prefix for page numbers honors `$config->pageNumUrlPrefix` and multi-language prefixes as well.
|
|
|
|
|
|
*
|
|
|
|
|
|
* @param Page $page
|
|
|
|
|
|
* @param array|int|string|bool|Language $options Optionally specify options to modify default behavior (see method description).
|
|
|
|
|
|
* @return string Returns page URL, for example: `/my-site/about/contact/`
|
