/**
|
||
|
|
* MySQL Resource
|
||
|
|
*
|
||
|
|
* Resource Implementation based on the Custom API to use
|
||
|
|
* MySQL as the storage resource for Smarty's templates and configs.
|
||
|
|
*
|
||
|
|
* Note that this MySQL implementation fetches the source and timestamps in
|
||
|
|
* a single database query, instead of two seperate like resource.mysql.php does.
|
||
|
|
*
|
||
|
|
* Table definition:
|
||
|
|
* <pre>CREATE TABLE IF NOT EXISTS `templates` (
|
||
|
|
* `name` varchar(100) NOT NULL,
|
||
|
|
* `modified` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP,
|
||
|
|
* `source` text,
|
||
|
|
* PRIMARY KEY (`name`)
|
||
|
|
* ) ENGINE=InnoDB DEFAULT CHARSET=utf8;</pre>
|
||
|
|
*
|
||
|
|
* Demo data:
|
||
|
|
* <pre>INSERT INTO `templates` (`name`, `modified`, `source`) VALUES ('test.tpl', "2010-12-25 22:00:00", '{$x="hello world"}{$x}');</pre>
