Ссылка на индекс в массиве в шаблоне SMARTY

Question

У меня есть переменная, которая является массивом в Smarty, и я пытаюсь выяснить, как получить эту информацию. Переменная называется $ COMMENTS, и я сделал $COMMENTS|@print_r, и вот что я получил:

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

            [parent_comments] => 
            [17] => 6731
        ) 
    )
)

Я пытаюсь извлечь из этого числа 11686 . Любая помощь? Я пробовал $COMMENTS[0][data:private][0], но это не сработало.

Любая помощь с благодарностью:)

Сначала поместите вывод print_r() в теги <pre>, чтобы он был читабельным.

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

Вы пытаетесь получить доступ к первому объекту в вашем массиве, $COMMENTS[0]. Поскольку это объект, а ваше свойство data является частным, вы не можете получить к нему доступ в Smarty. Вам нужно будет отредактировать класс ModComments_CommentsModel, чтобы предоставить вам доступ либо к свойству data, либо к ключу crmid этого свойства.

Пример:

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()}
