 Posted: Tue Feb 09, 2010 12:27 pm Post subject: solving __autoload() with your own |
 |
|
As Smarty (new version) tries to make use of autoload function ( spl_autoload_functions ), it creates a problem if you have to define your own __autoload() function.
So, in this case, you can re-write / adjust its autoload within your __autoload() function, and it just works good at the moment.
What you should do? In Smarty.class.php, find the below code and remove it.
| Code: | if (SMARTY_SPL_AUTOLOAD && set_include_path(get_include_path() . PATH_SEPARATOR . SMARTY_SYSPLUGINS_DIR) !== false) {
$registeredAutoLoadFunctions = spl_autoload_functions();
if (!isset($registeredAutoLoadFunctions['spl_autoload'])) {
spl_autoload_register();
}
} else {
spl_autoload_register('smartyAutoload');
} |
Then, modify your own __autoload() with something similar to:
| Code: | function __autoload($class_name='')
{
$class_name = strtolower($class_name);
if(substr($class_name, 0, 16) === 'smarty_internal_' || $class_name == 'smarty_security')
{
include __ROOT__ . '/library/classes/third/Smarty-3.0b7/sysplugins/' . $class_name . '.php';
return;
}
...
(rest of your code goes here)....
}
|
return; is an important issue, because, once your __autoload() knows that it was a Smarty's class and its file is included, you just have to quit the rest of the code.
This makes you upgrade to new version of Smarty with no compains with __autoload issue.
Thanks. |

That is not a good way, there is no need to edit the Smarty class. You shouldn't need to use __autoload(), you should instead register your autoloader with spl_autoload_register().
First, define this before including Smarty:
| Code: | | define('SMARTY_SPL_AUTOLOAD',1); |
Then, create your own autoload function:
| Code: | | function myAutoload() { ... } |
Then, register your autoloader:
| Code: | | spl_autoload_register('myAutoload'); |
Smarty will then add its own autoloader along with your own. |
