Configuration paths and URLs (Paths class)

Maintains lists of file paths or URLs, primarily used by the ProcessWire $config->paths and $urls API variables.

The Paths class is used by $config->paths and $config->urls (or just $urls). The $config->paths refers to server disk paths while $config->urls refers to web server URLs. All of the same properties are present on both, though several properties are only useful on one or the other (as outlined below). You can access a path or URL like this:

$path = $config->paths->templates; // i.e. /path/to/htdocs/site/templates/ 
$url = $config->urls->templates; // i.e. /site/templates/

The $config->urls property can also be accessed more directly via the $urls API variable (in PW 3.x+):

$url = $urls->templates; // i.e. /site/templates/

For $config->urls (or $urls), if you prepend http to any of the property names (making it camelCase) it will return the full http/https URL rather then the relative URL:

$httpUrl = $config->urls->httpTemplates; // i.e. https://domain.com/site/templates/
$httpUrl = $urls->httpTemplates; // same as above

You may optionally add your own properties as well. If you add a path/url without a leading slash “/” it is assumed to be relative to the root property. If it has a leading slash, then it is absolute.

// add new urls properties
$urls->set('css', 'site/templates/css/'); // relative to site root
$urls->set('uikit', '/uikit/dist/'); // absolute

// get properties that were set
echo $urls->get('css'); // i.e. /site/templates/css/
echo $urls->get('uikit'); // i.e. /uikit/dist/
echo $urls->get('httpCss'); // i.e. https://domain.com/site/templates/css/
echo $urls->get('httpUikit'); // i.e. https://domain.com/uikit/dist/
echo $urls->httpUikit; // same as above (using get method call is optional for any of these)

Do not set http properties directly, as they are dynamically generated from urls properties at runtime upon request.

In the examples on this page, you can replace the $urls variable with $config->paths if you need to get the server path instead of a URL. As indicated earlier, $urls can aso be accessed at the more verbose $config->urls if you prefer.

Please note in the property/method descriptions below that use the placeholder $urls refers to either $config->paths or $config->urls (or the shorter alias $urls). So $urls->files (for example) in the definitions below can refer to either $config->paths->files or $config->urls->files (or the shorter alias $urls->files). We use $urls here because it’s just the shortest option for example purposes.
