Templates from other sources
You can retrieve templates using whatever possible source you can access with PHP: databases, sockets, LDAP, and so on. You do this by writing resource plugin functions and registering them with Smarty.
See resource plugins section for more information on the functions you are supposed to provide.
Note:Note that you cannot override the built-infileresource, but you can provide a resource that fetches templates from the file system in some other way by registering under another resource name.
Example 15-9. using custom resources
// from PHP script // put these function somewhere in your application function db_get_template ($tpl_name, &$tpl_source, &$smarty_obj) { // do database call here to fetch your template, // populating $tpl_source $sql = new SQL; $sql->query("select tpl_source from my_table where tpl_name='$tpl_name'"); if ($sql->num_rows) { $tpl_source = $sql->record['tpl_source']; return true; } else { return false; } } function db_get_timestamp($tpl_name, &$tpl_timestamp, &$smarty_obj) { // do database call here to populate $tpl_timestamp. $sql = new SQL; $sql->query("select tpl_timestamp from my_table where tpl_name='$tpl_name'"); if ($sql->num_rows) { $tpl_timestamp = $sql->record['tpl_timestamp']; return true; } else { return false; } } function db_get_secure($tpl_name, &$smarty_obj) { // assume all templates are secure return true; } function db_get_trusted($tpl_name, &$smarty_obj) { // not used for templates } // register the resource name "db" $smarty->register_resource("db", array("db_get_template", "db_get_timestamp", "db_get_secure", "db_get_trusted")); // using resource from php script $smarty->display("db:index.tpl"); {* using resource from within Smarty template *} {include file="db:/extras/navigation.tpl"} |
