Problem with custom function "URL"

[GAngZta85]

Since 3.1.28 the smarty autoloader tries to load the class Smarty_Internal_Compile_URL.
This will not work because URL is a custom function.

In 3.1.27 it is all ok.

My custom function (plugins/function.URL.php):

function smarty_function_URL($params, $template) {
        $sPath = ifsetter($params['path'], '');
        return MSE()->Language()->getUrl(['sPath' => $sPath]);
}

Template example: {URL path=$i1}

On all tags Smarty does check if a class Smarty_Internal_Compile_{tag} does exist. If not it looks for a plugin in the plugin folder. This is how all Smarty 3.1 versions work. Nothing has changed there.

Your example does work at my place.
So what kind of error do you see?

Do you have other autoloader in your application?
A problem we have seen sometimes in the past is that false was returned if the class is not found.
This is wrong implementation. An autoloader must always return without a value.

Thanks for your reply.
Actual we use our system autoloader and the smarty autoloader. The system autoloader returns nothing "return;"
In both autoloader I insert an echo to see what class name was passed as parameter. In the output I can see both autoloader are called. At first the smarty autoloader then from the system.
The last class is called "Smarty_Internal_Compile_URL". Then I get a empty page. All neccessary plugins are available

Calling the autoloader for "Smarty_Internal_Compile_URL" is correct because the compiler does call the class_exists() method for it. That can't be the problem. It must be something else. Do you get compiled templates? Check the PHP error_log if something is reported there.

As there is no further reply this issue gets closed.

I think the compiler shall not check if class Smarty_Internal_Compile_URL exists if url is registered as plugin. Suddenly my URL plugin is not working anymore. Please reopen this issue.

[uwetews]

The compiler always checks if an internal compile class does exists. if this is not the cases it checks registered plugins.

Note that plugin tag names are case sensitive. If you use {URL} it must registered as 'URL'.

It does work at my place.

[ovidiugabriel]

I am using {url}, not {URL}. The plugin is registered as follows:

$_smarty->registerPlugin(Smarty::PLUGIN_FUNCTION, 'url',  'smarty_function_url');

I will be back with a backtrace if the problem is still persistent.

[ovidiugabriel]

You say: "The compiler always checks if an internal compile class does exists. if this is not the cases it checks registered plugins." / It should not be the other way around: "The compiler always checks checks registered plugins, if this is not the cases, checks if an internal compile class does exists?".

Because if I do not have the class, Smarty will throw exception and become unusable.

Not sure if it could be related to #199

This seems fixed.
