How to pass Smarty variable to PHP function?

[Michael F]

Greetings, I'm writing a custom PHP function in the Smarty plugins directory. The problem is that I need to use the $affiliateid variable but it seems that it does not work at all, and not recognized by the function.

 

Does anyone have a clue on how to use or pass a Smarty variable in PHP?

 

Thank you

Update:

 

A sample code of what I'm trying to achieve:

<?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File:     function.*
* Type:     function
* Name:     aff
* Purpose:  outputs a random magic answer
* -------------------------------------------------------------
*/
function smarty_function_aff($params, &$smarty)
{
       //none of the following display the affiliate id when called in template.
	print $affiliateid;
	echo $affiliateid;
}
?>

 

And in the template I use {aff} that supposed to display the affiliate ID of the user, however it doesn't display anything, just a blank white area. So my guess is that the PHP function does not recognize the $affiliateid variable.

 

I know I can use {$affiliateid} in the template itself to display the user affiliate ID but I have a different situation. The above code is just a sample.

 

Any suggestions?

 

Thank you in advance

To be honest, I don't have much experience in PHP, so I don't know actually. It's pretty much like the function code I added in my previous reply but with replacing the core code. I need to call that function in the affiliates.tpl file like that {aff}.

 

I'm wondering why is the function not able to read the $affiliateid variable. I'd greatly appreciate it if you could shed some light on this. Thanks

if you are writing a smarty function, this is how to pass the variable to it:

 

{functionName affiliateid=$affiliateid}

 

then from inside the function it self you can read it like that:

function smarty_function_functionName($params, Smarty_Internal_Template $template)
{
   $affiliateid = $params['affiliateid'];
}

I'm trying to append the affiliate ID to URL. I modified my code to contain what you've mentioned but I couldn't make it work.

 

<?php
/*
* Smarty plugin
* -------------------------------------------------------------
* File:     function.*
* Type:     function
* Name:     aff
* Purpose:  outputs a random magic answer
* -------------------------------------------------------------
*/
function smarty_function_aff($params, &$smarty)
{
          $affiliateid = $params['affiliateid'];
          $refflink = 'http://example.com/*?aff=' . $affiliateid .'';

          print $refflink;
}
?>

 

Still the $affiliateid doesn't seem to work as if it is not even exists. It prints only the first part of the URL without the affiliate ID, like this: http://example.com/*?aff=

What I'm missing here?

you did this part yet?

{aff affiliateid=$affiliateid}

 

you may need to make sure that $affiliateid has a value first!
