//readme file summary read.
Is there any useful information available or can someone tell - - about how to migrate smarty from 2.x to 3?.
I've been watching all the betas and RCs and been waiting for a stable release of smarty 3.
I have a class called template which extends the smarty class and puts to use some of the php magic methods.
One of the observation I noticed that is that smarty does not longer use all variables as global to all templates. This makes the process a bit tricky for these that have already running the code implementing it in such way.
Here is the class extension, It was cleaned to just reflect the current example.
| Code: | //$smarty_version = "2.6.26";
$smarty_version = "3.0.7";
require_once "library/Smarty-$smarty_version/libs/Smarty.class.php";
class template extends Smarty {
function __set($setting,$value)
{
if(is_array($value)) {
foreach($value as $s =>$v) {
$this->_tpl_vars[$setting][$s] = $v;
}
} else {
$this->assign($setting,$value);
}
}
function __get($setting)
{
return (isset($this->_tpl_vars[$setting])? $this->_tpl_vars[$setting]:null);
}
} |
Now, I noticed that Smarty now treats new variables as objects.
How does this play with the templates?. I also noticed the scope might have changed. And the usual "assign" method, is not longer viable as perhaps other might be as I saw there is a new "assignGlobal", which I assume takes over.
All these are really huge changes, that fundamentally will need us to make changes to a bulk of the existing code in our projects, to successfully migrate.
Now, out of the box, just downloaded a copy of the latest smarty and it not properly ran, I will smart a new topic for this error as does not relate to the above topic.

| Read the SMARTY2_BC_NOTES and README files that come with the Smarty 3 distro. The documentation is a good start too. It isn't all that different. Don't assume assign() is gone just because you don't see it in the top level class file. |

That is what the very first line of the post means. Actually I had looked the read me, and looked the SMARTY2_BC after I posted this.

Never said it was gone. What I said is it is fundamentally changed.

Nothing has changed for existing Smarty2 appilcations on assign(), fetch()
and display(). The major changes are under the hood.
You can use the following setter/getter
| Code: | function __set($setting,$value)
{
$this->assign($setting,$value);
}
function __get($setting)
{
return $this->getTemplateVars($setting);
}
