The playground

The playground is an application for trying templates: type a template and its data - a JSON object whose keys become variables - and the result shows beside it. The address bar always holds both, so a link shares the example.

It renders the way a page's PHP can render any PAD source, with padCode():

<?php

  $data = json_decode ( '{ "name": "Ann", "tags": [ "red", "blue" ] }', TRUE );

  $name = $data ['name'];
  $tags = $data ['tags'];

  $html = padCode ( '<b>{$name}</b>: {tags}{$tags}{notLast@tags}, {/notLast@tags}{/tags}' );

?>

<p>{!html}</p>

Because it runs what it is given, the playground answers this machine only, and a template there may not call PHP functions, sees no request values and no database, and gets five seconds, 64 KB of source and 256 KB of output. The output shows in a sandboxed frame, where the rendered page's scripts do not run. Tags that read files or fetch URLs still work - on this machine, for its own user.
