<?php
// 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");
?>

希望本文所述对大家基于smarty的php程序设计有所帮助。
