如何从php函数访问smarty的foreach迭代？ （Smarty 2.6）

Question

Question

Say I have

{php}
    function hello(){
{/php}
    <div class="hello">{$smarty.foreach.panellist.iteration}</div>
{php}
    }
{/php}

Then down below I call:

{foreach from=$channelObj->get_panellist_primary('','','pan_ptyid,pan_label1,pan_label2') item=panelObj name=panellist}
        {php}hello(){/php}
{/foreach}

I'm getting this error:

PHP Fatal error: Using $this when not in object context in /var/www.app1/theURL/otherthings/channel.tpl.php on line 197

Why doesn't this work? How can I access the iteration of this foreach from inside the function, preferably without passing a parameter?

More Details

Since I know you'll tell me {php} is deprecated...the reason I am using it is because I'm being asked to make a really complicated template, so I need complicated functions to build it without it becoming a mess, and I've never used smarty before. I'm on a deadline and I'm already late, so I can't learn the correct methodology of smarty. The only way I would know how to manage this code is with regular PHP, but my boss is insisting I make the whole thing with smarty...no PHP or Javascript allowed.

Thanks!

Answer 1

This is horrible style of coding, it's not a solution to use such code because you are in hurry. And if you don't know at all some technology, you shouldn't take money for this.

You could use in Smarty:

{foreach from=$x item=panelObj name=panellist}
    {assign var="iteration" value=$smarty.foreach.panellist.iteration}
    {php}hello(){/php}
{/foreach}

And in PHP function:

function hello()
{
    global $smarty;
    ?>
    <div class="hello"><?php echo $smarty->get_template_vars('iteration'); ?>
    </div>
<?php
}

and it will work (I've tested it) but I wouldn't even try to use such code for any project

Answer 2

scope=global is required for access variable from foreach!

{assign var=SenderID value=$Nachricht.sender_id scope=global} 
{php} echo $smarty->getTemplateVars('SenderID'); {/php} 

or

{assign var="edit_ticket_id" value=$ticket.ticketRaw['edit_old_ticket_id'] scope=global}

{php} global $smarty; var_dump($smarty->get_template_vars('edit_ticket_id')); {/php}
