Page metadata: meta

A page with PHP sets $title for its wrapper in its .php. A plain .pad, or an .html page dropped into the application, says it with {meta}:

{meta title='Monthly report', layout='_layouts/report'}

<p>{$title}: revenue 12.500</p>

What it can say

• title='Monthly report' - any name that is not one of the words below becomes a variable of that name, so the wrapper's <title>{$title}</title> shows it.
• layout='_layouts/print' - the page is framed by that layout, as extends does.
• cache=600 - the page's own time in the server cache, in an application that has its page cache on; cache=0 keeps the page out of it.
• access= and sitemap= - kept for the access rules and the sitemap to read; padMeta ( 'access' ) answers for the page being built, padMeta ( 'sitemap', 'reports/monthly' ) reads another page's file.

When it is read

The tag is read while the page is assembled: after the PHP of _inits.php and of the page itself, before anything renders - so it has the last word over a $title the PHP set, and its values may use the PHP's variables. It must stand directly in the page's own template; the tag itself prints nothing. The cache time is read from the file before the cache is looked in, so there only plain values count.
