smarty->assign() doesn't evaluate the code?

I am writing a PHP-Script which assigns some html-code to my templates.

PHP-File:

$smarty->assign("PLACEHOLDER", getCode());
$smarty->display('index.html');

function getCode(){ 
     return "{literal}some code which I want to get evaluated ...{/literal}"; 
}

HTML-File:

{$PLACEHOLDER}

I know i could use {eval var=$PLACEHOLDER} instead of {$PLACEHOLDER} which would work perfectly, the only thing is that I have about 500 templates and I won't change the html-code of all of them. Is there a way I can evaluate the code directly when I assign it to the template?

Solution

  • use {eval}

    {eval} is used to evaluate a variable as a template. This can be used for things like embedding template tags/variables into variables or tags/variables into config file variables.

    If you supply the assign attribute, the output of the {eval} function will be assigned to this template variable instead of being output to the template.

    So in your HTML-File use the following:

    {eval var=$PLACEHOLDER}
