Question

Hello I’d like to assign a variable in a template file from prestashop with smarty.
How can I do this?

I have following code so far:

{$db = DB::getInstance()}
{$id_lang = Context::getContext()->language->id}
{$sql = 'SELECT value FROM ps_feature_value_lang WHERE id_feature_value = 29 AND id_lang = $id_lang'} <- this is not working

Answer 1

It doesn’t work because the variable is inside the quotes. You need to concatenate the string with the variable.
Not tested, but it should be something like that:

{$sql = 'SELECT value FROM ps_feature_value_lang WHERE id_feature_value = 29 AND id_lang = '|cat:$id_lang}
