Referencing an index in an array in SMARTY template

I have a variable that is an array in Smarty, and I am trying to figure out how to retrieve that information. The variable is called $COMMENTS and I did $COMMENTS|@print_r and this is what I got:

Array ( 
    [0] => ModComments_CommentsModel Object ( 
        [data:private] => Array ( 
            [0] => 11686

I am trying to retrieve the 11686 number from that. Any help? I have tried $COMMENTS[0][data:private][0] but that didn't work.

Any help greatly appreciated :)

First, put print_r() output into <pre> tags so it is readable.

Array ( 
    [0] => ModComments_CommentsModel Object ( 
        [data:private] => Array ( 
            [0] => 11686 
            [crmid] => 11686 
            [1] => 1679 
            [smcreatorid] => 1679 
            [2] => 1679 
            ...
        )
    )
    ...
)

You're trying to access the first object in your array, $COMMENTS[0]. Since that it is object, and your data property is private, you cannot access it in Smarty. You would have to edit the ModComments_CommentsModel class to give you access to either the data property or the crmid key of the property.

Example:

class ModComments_CommentsModel {

    // ...

    public function CrmId(){
        return $this->data['crmid'];
    }

    // ...

}

{* template *}
{$COMMENTS[0]->CrmId()}

{* might have to assign before using method call *}
{assign var='comment' value=$COMMENTS[0]}
{$comment->CrmId()}
