Call smarty variable from html instead of php

问题

HTML CODE:

<html><body>
{section name=a loop=$items}
{$items[a].title}
{include file="/directory/showstuff.html" video=$items[a]}
{/section}
</body> </html>

PHP CODE:

$pid = '12';

$items = $cbvid->get_channel_items($pid);

assign('items',$items);

This is perfectly working fine, with the integer 12 being my php code. However, I wanted to add the integer 12 and call it from the html code, but it didn't work.

I tried:

<html><body>
{section name=a loop=$cbvid->get_channel_items(12)}
{$items[a].title}
{include file="/directory/showstuff.html" video=$items[a]}
{/section}
</body> </html>

But it didn't work. How can I do it?

回答1:

Just don't do it. That looks like if you would like to move business logic to representation layer - that is not what Smarty is used for. Prepare data beforehand, then give it to template.

But if you really want it to work, use foreach

<html><body>
{foreach  from=$cbvid->get_channel_items(12) item=video}
{$video.title}
{include file="/directory/showstuff.html" video=$video}
{/foreach}
</body> </html>

The reason why it did not work with sections, was because you have no $items variable defined, still, you are trying to get value of it. This is where you need to use assign.

<html><body>
{assign var="items" value=$cbvid->get_channel_items(12)}
{section name=a loop=$items}
{$items[a].title}
{include file="/directory/showstuff.html" video=$items[a]}
{/section}
</body> </html>

Still, I prefer foreach.
