What is wrong with this Smarty php templating code? If I include either of these two loops individually in the file, they work. But if I have them both in the file like below only the first loop gets completed.
{include file="vote_js.tpl"}
{section name=i loop=$posts}
{include file="posts_bitother.tpl"}
{/section}
{section name=j loop=$posts2}
{include file="posts_bitposts.tpl"}
{/section}
So for example
{section name=j loop=$posts2}
{include file="posts_bitposts.tpl"}
{/section}
works fine on it's own.
Why is this happening and what is the way around it?
Solved it, was an error in my smarty code later on

I'm working on a legacy application that is written in PHPfox.
There is this foreach loop in one of my view.html.php files:
{foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
<td>{$aReportSubmission.event_name}</td>
{/foreach}
The problem is that $aReportSubmission.event_name is an array and it gets outputted as Array. How can I loop through this variable and show the individual events?
PHPfox uses template tags that resemble Smarty template engine.
The following did NOT work for me:
{foreach from=$aReportSubmission.event_name item=iEvent} {iEvent},{/foreach}
I can see $ is missing before iEvent inside the inner loop
Check if this is works
{foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
<td>{foreach from=$aReportSubmission.event_name item=iEvent} {$iEvent},{/foreach}</td>
{/foreach}
Try with this
{foreach from=$aReportSubmissions key=iKey item=aReportSubmission}
{$aReportSubmission.event_name|print_r}
{/foreach}
HTML CODE:
<html><body>
{section name=a loop=$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?
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.
I would like to define smarty block names according to smarty data, but I can't seem to do it.
Example:
{foreach $array as $code}
{block name=block_$code}
<div id='{$code}'></div>
{/block}
{/foreach}
My purpose is to extend a specific block_$code block by a child template. Is this possible or is there some other trick I could use to do this?
Thanks.
You can use the {assign} block and the cat modifier. For example
{foreach $array as $code}
{assign var=foo value="block_"|cat:$code}
{block name=$foo}
<div>
{/block}
{/foreach}
N.b. I've not tested this, but it should work. You might also be able to short-circuit this and just use {block name="block_"|cat:$code}.
I was able to find the following link from 2011 indicating that this wasn't possible at that time. I suspect it still isn't:
http://www.smarty.net/forums/viewtopic.php?t=19805&highlight=block%20variable%20name
The good news it that I was able to figure out how to make my code work without it. I wanted to be able to override just one of the divs defined by the foreach. Here's how I can do it:
Parent:
{foreach $array as $code}
{block name=code_loop}
<div>Normal Stuff</div>
{/block}
{/foreach}
Child:
{block name=code_loop}
{if $code == 'code of interest'}
<div>New Stuff</div>
{else}
{$smarty.block.parent}
{/if}
{/block}
For smarty's html_options function, is there a way to avoid having to do this (other than not using smarty that is)?
{if $smarty.post}
{html_options name=option_1 options=$options selected=$smarty.post.option_1}
{else}
{html_options name=option_1 options=$options}
{/if}
I realize that it won't show up in the template, but it seems like a bad practice to leave something that is not defined in the template (it also fills up my error logs with noise about undefined indexes).
[edit]
What I am looking for is a way to do it like this without having the undefined index errors show up, as well as reducing the smarty noise in the template files.
{html_options name=option_1 options=$options selected=$smarty.post.option_1}
I guess it would more likely be a modified html_options plugin?
[edit]
As per #mmcgrail's idea:
{if isset($smarty.post.option_1)}
{assign var=selected value=$smarty.post.option_1}
{else}
{assign var=selected value=$default.option_1}
{/if}
{html_options name=option_1 options=$options selected=$selected}
I find this even worse because it is creating new variables in the template, straying from the supposed goal of smarty.
I guess this works:
or:
<?php
//[... snip ...]
$option_1 = isset($_POST['option_1'])? $_POST['option_1'] : $default['option_1'];
$template->assign('option_1', $option_1);
$template->display('my_template.tpl');
And in the template:
{html_options name=option_1 options=$options selected=$option_1}
But then what is the point of smarty keeping track of all of the post/get/request/cookie/server/constants if you can't use them in the template without doubling the amount of code you have to write?
try this
{if isset($smarty.post)}
{html_options name=option_1 optins=$options selected=$smarty.post.option_1}
{/if}
i think that answer your question
I know it's like 12y later but ...
While migrating an app to php 8.1 I just hit this same issue :)
So the real solution that worked was
{html_options name=option_1 options=$options selected=$default.option_1|default:""}
Turns out that without writing a separate plugin what I want is not possible... maybe I will do that, something like:
{html_options name=option_1 options=$options selected=$default.option_1 post=option_1}
Here is the Sample Code:
{section name="firstlevel" loop=$xxx}
<ul>
{section name="secondlevel" loop=$xxx[firstlevel]}
<li>$xxx[firstlevel][secondlevel].values</li>
{/section}
</ul>
{sectionelse}
No values
{/section}
{if $smarty.section.firstlevel.last}
{include file="pagination.tpl"}
{/if}
I have limited 10 records per page, but this smarty code not calling the include file pagination. Please suggest what wrong in it or give idea...
I'm not a Smarty guru but I believe "last" only returns true while in the section. This would probably be preferable anyway as there is little or no use showing pagination when there are no records.
{section name=firstlevel loop=$xxx}
<ul>
{section name=secondlevel loop=$xxx[firstlevel]}
<li>$xxx[firstlevel][secondlevel].values</li>
{/section}
</ul>
{if $smarty.section.firstlevel.last}
{include file="pagination.tpl"}
{/if}
{sectionelse}
No values
{/section}
