Referencing an index in an array in SMARTY template - php

Question

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
[crmid] => 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()}
