 Posted: Thu Jun 10, 2004 6:19 pm Post subject: Hava a look at this small class to build smarty-webbpages |
 |
|
Hi all, I´m kind of new in Smarty, but I have put this together. You can see this in work here:
http://euroaccident.supportcenter.se/page.php?docid=18 or here
http://www.ifkvaxjo.se
I have made a simpel class and a php-page that get the webbpages and put them together by Smarty. I would be wery happy if anybody, could just take a look on this and, point out the worst misstakes!!
This is supposed to be a small but nice way to build a webbproject, planning on writing some plugins, and som working admin pages this summer. I use ADOdb, as db-layer
Well, this is the code:
1. run page.php
2. creats cacheid, and setup cache
3. check if the page is already in the cache.
4. if not, create the page
5. display page, from cache of from db
page.php
| Code: | <?
/**
* Junior page
* package Junior cms
* ver 0.0.2
* date: 2004-06-05
**/
error_reporting(E_ALL ^ E_NOTICE);
session_start();
require_once 'setup.php';
$smarty->debugging_ctrl = 'URL';
require_once 'class/junior.class.php';
$junior = new junior_start($docid,$db);
//CREATE CACHEID
$my_cacheId = $_GET['docid'];
//SET CACHE
$junior->setCache($my_cacheId,$smarty);
// CHECK IF PAGE EXISTS -------------------------------------------
// IF NOT SEND TO 404-PAGE MISSING PAGE ---------------------------
if($junior->getTpl() != "" or $junior->getTpl() != 0){
// PAGE EXISTS - NOW LOOK FOR CACHE ---------------------------------
if(!$smarty->is_cached($junior->getTpl(), $junior->getCacheID())) {
//get content to the page
$doc = $junior->getDoc($_GET['docid'],$db);
//assign timestamp
$smarty->assign("timestamp", $junior->getTimestamp());
//assign to tpl
$smarty->assign("data", $doc);
}
// DISPLAY PAGE - CACHED OR NEW
$smarty->display($junior->getTpl(), $junior->getCacheID());
} else {
// NOPAGE EXISTS SEND TO 404-PAGE
Header("Location: /nopage.html");
}
$db->Close();
?> |
and the class:
| Code: | <?PHP
/**
* Junior junior.class.php
* Junior cms
* ver 0.0.2
* 2004-05-09
*/
class junior_start
{
//var
var $tpl;
var $login;
var $doctxt_source;
var $cache_my_cache_id;
var $user_id;
var $user_name;
var $numeric_value;
var $error;
var $flag;
function junior_start($docid,$db)
{
if($this->setNumericValue($docid) == true) //validat as numeric id for page
{
//ladda tpl & login-flagga
$sql = "select tpl,login from junior_doc where docid=".$this->getNumericValue()." limit 1";
$result = $db->GetRow($sql);
$this->tpl = $result[0];
$this->login = $result[1];
}
}
//SET CACHE
function setCache($my_cacheId,&$smarty)
{
if($_SESSION["junior_session_login"] != "TRUE"){
$smarty->caching = true;
$smarty->cache_lifetime = 3600000000;
$this->cache_my_cache_id = $my_cacheId;
}
}
//GET A TEXT TO PUT ON THE PAGE, THE CONTENT SAVED IN DB.
function getDoc($docid,$db)
{
$sql = "select doctxt_source,doctxt_timestamp from junior_doctxt where doctxt_id=$docid limit 1";
$result = $db->GetRow($sql);
$this->doctxt_source = $result[0];
$this->doctxt_timestamp = substr($result[1], 0, 10);
return $this->doctxt_source;
}
// set & get & val
function setNumericValue($numeric_value)
{
if(is_numeric($numeric_value)) {
$this->numeric_value = $numeric_value;
return true;
} else {
$this->error = "Måste vara numeriskt";
return false;
}
}
function getNumericValue()
{
return $this->numeric_value;
}
function getCacheID()
{
return $this->cache_my_cache_id;
}
function getSource()
{
return $this->doctxt_source;
}
function getTimestamp()
{
return $this->doctxt_timestamp;
}
function getTpl()
{
return $this->tpl;
}
function getLogin()
{
return $this->login;
}
function getUserId()
{
return $this->user_id;
}
function getUserName()
{
return $this->user_name;
}
}
?> |
and a simpel tpl:
| Code: | <table width="100%" cellspacing="0" cellpadding="8" border="0">
<tr>
<td>{$data|junior_eval}</td>
</tr>
</table> |
and at last a small eval plugin
| Code: | /* {$data|junior_eval}*/
function smarty_modifier_junior_eval($doc) {
global $smarty,$junior;
$smarty->assign('doc_to_eval', $doc);
$evald = $smarty->fetch('eval.tpl', $junior->getCacheID());
return $evald;
}

Do you mean that this document will never expired? if you want to do this,you can set the cache_lifetime value to -1.
$smarty->cache_lifetime = -1 |

I think you use the function empty() to judge this.
if the value of a variable is zero,empty() will return false also. |

Thanks alot for the comments, wery useful!
Yes, the idea is to not clear the tpl until it the page is updater by the admin page, so I will change the lifetime to -1
I see that emty() can do the job in a more clean way. I will correct that too.
