How add last order with date in blockuserinfo.tpl

[Patryk Tchórzewski]

Hi i try show last order in user nav i am add code 

{if $orders && count($orders)}
	{foreach from=$orders item=order name=myLoop}
		{if $smarty.foreach.myLoop.first}
			<a class="color-myaccount" href="javascript:showOrder(1, {$order.id_order|intval}, '{$link->getPageLink('order-detail', true)|escape:'html':'UTF-8'}');">
              	<p>{l s='From:'}</p>
              	<p>{dateFormat date=$order.date_add full=0}</p>
			</a> 
		{/if}
	{/foreach}
{else}
<p class="alert alert-warning">{l s='You have not placed any orders.'}</p>
{/if}

But this code working only on when open is Order history page (history.tpl) I try add code in HistoryController after history.tpl is define

I try with: 

$this->setTemplate(_PS_THEME_DIR_.'index.tpl'); {*not-working*}
$this->setTemplate(_PS_THEME_DIR_.'/modules/blockuserinfo/nav.tpl'); {*not working*}
$this->setTemplate(_PS_THEME_DIR_.'modules/blockuserinfo/nav.tpl'); {*not working*}

I am always see that same issue 
 

/tools/smarty/sysplugins/smarty_internal_templatebase.php(157) undefined index orders

Anyone can help
