Hi,

I have a quick question. I want to display an extra field value on the cart page, and then do some database lookups with that value. For this I need to access a smarty variable in a {php}{/php} section.

I got it working on an install of xcart 4.4.1. In this version I have:

Extra field value:

{$product.extra_fields.0.value}

Then in the php section:

{php}$variable=$this->_tpl_vars['product']['extra_fields']['0']['value'];{/php}

Now I want to move this over to my current install, which is 4.1.9.

Extra field value (slightly different):

{$products[product].extra_fields.0.value}. 

php section:

{php} ?? {/php}

The {php} bit I did for the version 4.2 doesn't work. Does anyone know how I can do this?

Thanks,

PHP Code:

{php}$variable=$this->_tpl_vars['products']['product']['extra_fields']['0']['value'];{/php}

The recommended method is here:

// get assigned template var 'foo'
$myVar = $smarty->get_template_vars('foo');

// get all assigned template vars
$all_tpl_vars = $smarty->get_template_vars();

// take a look at them
print_r($all_tpl_vars);

Thanks for all your help! With both your replies I managed to get it working.

What worked was:

{php}$variable=$this->_tpl_vars['products'][0]['extra_fields']['0']['value'];{/php}  

Annoyingly it has to have a the cart id value [0], and ['product'] didn't work. I sorted it out by having a variable which I looped:

{php}
$cartid=0;
$variable=$this->_tpl_vars['products'][$cartid]['extra_fields']['0']['value'];
$cartid=$cartid+1;
{/php}  

This is very ugly but it works. Thanks again.
