在smarty中访问嵌套数组

Question

I am trying to access a nested array inside html code using smarty. For example i have an array that looks like this: Array(customer)[name, age, id[firstname, lastname, birthdate]]. I have been trying something like this:

{foreach from=$customer item=foo} 
    Customer id: {$foo.id} 
{/foreach}

But this doesent print any values to the page. However with this syntax

{foreach from $customer item=foo}
    {$foo.id} // or {$foo.id.0}
{/foreach}

It prints out: Array

How do i access the values of nested array using smarty?

Answer 1

Try this:

{foreach from=$customer item=foo} 
    Customer name: {$foo.id.firstname} {$foo.id.lastname}
{/foreach}

Smarty will compile it to something equivalent with:

foreach ($customer as $foo) {
   echo('Customer name: '.$foo['id']['firstname'].' '.$foo['id']['laststname']);
}
