Concatenate smarty variable with foreach - smarty

In a .tpl file, I'm using a smarty foreach to concatenate values from an array, separated by pipes "|" :
{foreach from=$attachments item=attachment}{$attachment.file}|{/foreach}
This writes : test1.mp3|test2.mp3|test3.mp3|
Now... I need to pass this result as a variable in an href link.
The problem is I can't include my foreach inside the a href tag.
Also I tried to assign this result to a new smarty variable but can't figure how to do it.
Any help would be great.
Thanks.

You can do it this way:
{assign var=result value=''}
{foreach from=$attachments item=attachment}
{assign var=temp value=$attachment.file}
{assign var=result value=$result$temp|}
{/foreach}

How to correctly copy an array element in smarty

I want to copy array element into another array element.
I have an smarty array $product: {["link"]=> "aaa" ["test"]=> 22 }
I want to have: {["link"]=> "aaa" ["test"]=> 22 ["url"]=> "aaa" }
I tried variations of
{assign var=$product.url value=$product.link}
{assign var=product.url value=product.link}
{assign var='product.url' value=$product.link}
etc.
But this either causes errors or the variable is not being rewritten.

How to remove duplicate values on array using Smarty

I have an array that have duplicated values, I want to print the value only once no matter how many time it exist on the array.
This is the code that I have:
{foreach item="item" from=$root.page.news.item }
{foreach from=$item.Tags item=tagitem key=kex}
{$tagitem}
{/foreach}
{/foreach}
This is what it prints right:
kim000kardashian
kim000kardashian
miley000cyrus
miley000cyrus
kim000kardashian
irina000shayk
and this is what I am looking to print
kim000kardashian
miley000cyrus
irina000shayk
Is there a way to achieve this only using Smarty Templates? or any way that I can use on the .tpl files?
Thanks in advance
{foreach item="item" from=$root.page.news.item }
{foreach from=$item.Tags item=tagitem key=kex}
{if !$done.$tagitem}
{$done.$tagitem = 1}
{$tagitem}
{/if}
{/foreach}
{/foreach}
I am not sure it works with all the versions.
Maybe it would be a bit cleaner to call an array_unique() in the php.

Counter inside iterate smarty loop

I have this smarty code :
{iterate from=fruits item=fruit}
....
{/iterate}
I want to have a counter inside this loop that accept a start value and increase by one until the loop continues.
I should i use? i am not good in smarty.
Thank you.
You can use the .iteration
{foreach from=fruits item=fruit}
current item #: {$smarty.foreach.fruits.iteration}
{/foreach}
source: http://www.smarty.net/docsv2/en/language.function.foreach.tpl#foreach.property.index
In case you have something like this:
{foreach from=$fruits item=fruit} {/foreach}
Instead of this:
{foreach from=fruits item=fruit} {/foreach}
You should use this syntax:
{foreach from=$fruits item=fruit name=counter}
Iteration no {$smarty.foreach.counter.iteration}
{/foreach}

Smarty: cannot recognize continue tag

all im trying to do is to use the simple continue tag but it keeps giving me error like this:
string(145) "Smarty error: [in module_db_tpl:onlyimage4;image_detail line 26]: syntax error: unrecognized tag 'continue' (Smarty_Compiler.class.php, line 590)"
my code is as follow:
{foreach from=$itemlist item="item"}
< .. SOME CODE ..>
{if $maxCol == $colm}
</div>
{assign var ='colm' value = 0}
{$row++}
{continue} **<- THIS IS THE PROBLEM**
{/if}
<.. SOME CODE ..>
{/foreach}
does anyone have any idea whats wrong, I've been googling and see no comments of such sort everyone seem to suggest that this should work.. any ideas guys...
Old question, but you need to use: {$continue} (including the $)
For smarty 2:
I don't think the tag exists. if you read this thread you can see that there are people that want it, and a suggestion to fix it like so. (have not tried)
compiler.continue­.php
<?php
function smarty_compiler_con­tinue($contents, &$smarty)
{
return 'continue;';
}
?>
(Bold part my addition)
Create these two files (in this case just one) and put them into your plugins directory
(notice the naming convention compiler.xxx.php).
The good news is, for smarty 3 there is such a tag! see the manual, with example:
{$data = [1,2,3,4,5]}
{foreach $data as $value}
{if $value == 3}
{* skip this iteration *}
{continue}
{/if}
{$value}
{/foreach}
{*
prints: 1 2 4 5
*}

Smarty change elements in array

I have an array in my template files ($data) witch looks like this
$data.1.name
$data.1.date
$data.1.place
$data.2.name
$data.2.date
$data.2.place
$data.3.name
$data.3.date
$data.3.place
now I would like to check the entire array and remove an item where the date is older then today.
The date check i figured out but i'm stuck at removing the item.
So let's say item 2 is older, the result should look like
$data.1.name
$data.1.date
$data.1.place
$data.3.name
$data.3.date
$data.3.place
Anyone an idea how i do this? If it is at all possible?
{foreach from=$data item=val}
{if $val.date >= $smarty.now}
{$val.name}
{$val.date}
{$val.place}
{/if}
{/foreach}
