DB_DataObject and Smarty

05/10/2006, 19h30

Does anyone know of any tutorials out there that show how I can get smarty
working with DBDO? I've searched but haven't been able to come up with
anything beyond using DB::getAll() method. I'd rather stay away from using
that if at all possible. I'd rather use DBDO::find(). Here's one (among
many) attempt I made to get it to work:

sandbox.php:
<?php
$users = new Users();
$users->country = 'USA';
$users->limit( 10 );
$users->find();

$smarty = new Smarty();
$smarty->assign( 'users', $users );
$smarty->display( 'sandbox.tpl' );

?>

sandbox.tpl
<html><head><title></title></head><body>
{section name=bar loop=$users}
Current User: {$users[bar].uid}<br>
{/section}
</body></html>

but doing that gives me an error saying that it cannot use object of type
Users as array. Am I just doing it wrong? Do I need to implement the
iterator interface in the Users class?

If someone can offer any pointers as to what I'm doing wrong or if you can
point me to a howto/tutorial on the web, that'd be awesome!

thnx,
Chris

Yes, you probably do need to implement the iterator interface in the
users class. I believe that Smarty uses foreach loops for all iteration
so that objects with iterator interfaces can be used. You should also
get the same error/result if you were to add the following to sandbox.php:

foreach( $users as $user ) {
echo "Current User: ".$user['id']."<br>";
}

Well, I was able to use MDB2_Iterator as my iterator. After instantiating
and initializing it, I'm able to iterate through it fine using straight PHP
(similar to the above code), but I can't get it to work in Smarty. I no
longer get the error (using ->register_object() but I do get it
using ->assign()) but now it's not displaying anything; it doesn't appear
that Smarty is iterating through anything.

Is there something I'm missing?

thnx,
Chris

Neither register_object() nor assign() were working for me so I decided to
try assign_by_ref() as sort of a last ditch attempt. Surprisingly, it
worked!

However, I'm not sure if that is the correct solution. Why did
assign_by_ref()
work and register_object(), at the very least, did not?

thnx,
Chris

I would like to accomplish the following:

1. Have Smarty always look in path /home/e-gov/htdocs/templates for templates.
That works fine if I hard code the path in the display() function.

2. Have Smarty always look in the that

/home/e-gov/htdocs/tempates_c or
/home/e-gov/htdocs/templates/templates_

Can this be done?

Thanks

I find it easiest to extend the Smarty class and set that stuff in the
constructor, e.g. in php4:

require_once 'Smarty.class.php';

class Template extends Smarty
{
function Template()
{
//Call Smarty Constructor
$this->Smarty();

//Determine where the smarty files are -- slashes on both
sides
$base_path = _LOCALPATH.'/some/path/';

//Assign Smarty defaults -- trailing slash only
$this->template_dir = _LOCALPATH.'/public_html/templates/';
$this->compile_dir = $base_path.'templates_c/';
$this->config_dir = $base_path.'configs/';
$this->cache_dir = $base_path.'cache/';
$this->plugins_dir = array(SMARTY_DIR.'/plugins',
$base_path.'plugins/');

//cache settings, for when we do use caching
$this->use_sub_dirs = 1; // enable cache subdirectories
$this->cache_lifetime = 3600; // 60 minutes

//caching turned off by default
$this->caching = 0;

}
}

Maybe there's a better way, but this works well for me.
