registerPlugin modifier unable to call with reference

[meesha81]

In v4.5.1 I am not able to use php function called by reference.

php function like (use case: Every function call increase and return the number of tabindex)

function tbx(&$tabindex) {
   $tabindex++;
   return $tabindex;
}

In tpl file called like:

{$tbx = 0}
.
.
.

tbx($tbx)

Pluign registered by $this->smarty->registerPlugin("modifier","tbx", "tbx");

But this cannot work because not passed by reference: PHP Warning: tbx(): Argument #1 ($tabindex) must be passed by reference, value given in ...

I am not able to find how to call custom modifier with reference.

If I leave tbx unregistered, there is smarty deprecated warning, but working fine, because of calling pure php function "tbx()".

Please, is it meant that the modifier could be called a reference? Or is there another way to solve this?

I have found it is propably similar to https://github.com/smarty-php/smarty/issues/964

I think this havent easy fix, but is possible to allow "force use some php function directly" ? Provide some php function whitelist for these type of issues?

Hi,

& is because of call by reference.

I need to $tbx|tbx show current value and increase $tbx. That's standard call by reference usage.

Calling php function directly (without registerPlugin) it is working fine, but smarty ends support for direct calling php functions. But smarty's registerPlugin do not allow/do not expect call by reference usage so you can't use this simple function now:(

Can you try to remove the Ampersand in this function, it looks strange. function tbx($tabindex) { $tabindex++; return $tabindex; }

Note: Problem is not with modifier {$tbx|tbx} (I don't need modifier) but I want to call PHP function like {tbx($tbx)}
This type of function call has new deprecation warning. Calling PHP function with referenced variable can be very useful.

Yes the new version broke around 30% of current project if i try to upgrade, is there a way to have direct call of php function? With an extension maybe?

You cannot use these functions at this time: https://github.com/smarty-php/smarty/issues/961#issuecomment-2020721907

@meesha81 for now, please consdier leaving your function unregistered. That will trigger a deprecation notice, but that shouldn't hurt anyone.

Closing this as this is a duplicate of #964
