I use Smarty 3.1.18 as a template engine in my project, After successfully encoding files (including .php,.tpl files and Smarty library) with all Obfuscation options checked, when i run my project getting following error

Fatal error: Uncaught exception 'LogicException' with message 'Function 'smartyAutoload' not found (function 'smartyAutoload' not found or invalid function name)' in C:\ccstack\htdocs\App_Encode\Smarty\libs\Smarty.class.php:0 Stack trace: #0 C:\ccstack\htdocs\App_Encode\Smarty\libs\Smarty.class.php(0): [obfuscated]() #1 C:\ccstack\htdocs\App_Encode\index.php(0): unknown() #2 {main} thrown in C:\ccstack\htdocs\App_Encode\Smarty\libs\Smarty.class.php on line 0

The patch which is provided by ionCube works for Smarty 2.* versions.
I tried replacing getContent() function in /libs/sysplugins/smarty_internal_resource_file.php with..

Code:

public function getContent(Smarty_Template_Source $source)
{
if ($source->timestamp) {
if (function_exists('ioncube_read_file')) {
return ioncube_read_file($source->filepath);
} else {
return file_get_contents($source->filepath);
}
}
if ($source instanceof Smarty_Config_Source) {
throw new SmartyException("Unable to read config {$source->type} '{$source->name}'");
}
throw new SmartyException("Unable to read template {$source->type} '{$source->name}'");
}

Please help me out!! Sad

The error is expected behaviour because the Encoder has renamed smartyAutoload and you are specifying its original name. Create an obfuscation exclusion list and exclude smartyAutoload from being obfuscated. _________________ Community Admin

Hi,
Thanks for replying .. Smile

I have created obfuscation exclusion list and mentioned all the classes and functions which were giving problem. I have encrypted both .js and .css files by mentioning in Non-PHP encryption extensions.
Now I am able to see the output of my page but not able to include external javascript or css files. Getting following error msg in firebug console... If i dont encrypt them then everything is working fine...

Code:

SyntaxError: missing ; before statement
!odMbo!

Code:

ReferenceError: jQuery is not defined
jQuery('#Div1').show();

My exclusion file contain following classes and Methods

.css and .js files are going to be sent directly to the browser by the web server. How will the browser know how to decrypt ionCube files? _________________ Community Admin

So basically you are saying ioncube_read_file function will not help in that case? .js and .css files are included in TPL files.

Not exactly, but you need to think about things a bit. A .css file is going to sent to the browser directly by the web server, so there's no chance for our software to process it. What you could do is create a php file whose job is to serve your css and js files. Pass it a parameter to say what file is to be served, and the script could then call ioncube_read_file() to decrypt the file and produce the content. So this keeps the files secure, but as the content has to reach the browser unencrypted, is there any point? Even if you prevented hot linking, the browser would still cache the js and css. To avoid that you could use headers to tell the browser not to cache, but then you're seriously impairing the end user experience by not leveraging browser caching. It's not a good path to be going down. _________________ Community Admin

Okay I get your point ...Now I am encrypting only .tpl and .php files.. Many a times I got following error Fatal error: Class '[obfuscated]' not found in... Same in case of functions and methods.. So I had to put most of my user defined functions and classes in Obfuscation exclusion file after that my application runs fine. Is it normal? Do I have any other option? Because the actual application for which I am going to use IonCube encoder is much bigger and contains many user defined classes and functions.

Names needing to be called from non-encoded files would need to be excluded from obfuscation because changing the names is what obfuscation does. So what would need to be excluded would depend on how much of the application is encoded. _________________ Community Admin
