Stamp for Craft

A tiny plugin for adding timestamp to filenames.

Usage

Use it like this:

<script src="{{ craft.stamp.er('/assets/build/js/scripts.js') }}"></script> 

Which results in:

<script src="/assets/build/js/scripts.1399647655.js"></script>

The er() method takes a second parameter for setting the format of the output. Possible values are file (default), folder, query and tsonly.

Example with folder:

<script src="{{ craft.stamp.er('/assets/build/js/scripts.js', 'folder') }}"></script> 

Result:

<script src="/assets/build/js/1399647655/scripts.js"></script>

Example with query:

<script src="{{ craft.stamp.er('/assets/build/js/scripts.js', 'query') }}"></script> 

Result:

<script src="/assets/build/js/scripts.js?ts=1399647655"></script>

Example with tsonly:

Timestamp is: {{ craft.stamp.er('/assets/build/js/scripts.js', 'tsonly') }} 

Result:

Timestamp is: 1399647655

URL rewriting

For methods file and folder you probably want to do some url rewriting. Below are some examples of how this can be done, adjust as needed for your server and project setup.

Apache:

# Rewrites asset versioning, ie styles.1399647655.css to styles.css.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.+)\.(\d{10})\.(js|css)$ $1.$3 [L]  # /assets/build/js/scripts.1399647655.js
# RewriteRule ^(.+)/(\d{10})/(.+)\.(js|css)$ $1/$3.$4 [L]  # /assets/build/js/1399647655/scripts.js

nginx:

location @assetversioning {
    rewrite ^(.+)\.[0-9]+\.(css|js)$ $1.$2 last;  # /assets/build/js/scripts.1399647655.js
    # rewrite ^(.+)/([0-9]+)/(.+)\.(js|css)$ $1/$3.$4 last;  # /assets/build/js/1399647655/scripts.js
}    

location ~* ^/assets/.*\.(?:css|js)$ {
    try_files $uri @assetversioning;
    expires max;
    add_header Pragma public;
    add_header Cache-Control "public, must-revalidate, proxy-revalidate";
}

Configuration

Stamp needs to know the public document root to know where your files are located. By default Stamp will use $_SERVER['DOCUMENT_ROOT'], but on some server configurations this is not the correct path. You can configure the path by setting the stampPublicRoot setting in your config file (usually found in /craft/config/general.php)

####Example

'stampPublicRoot' => '/path/to/website/public/',
