How do I check if file exists in Smarty 2? I mean something like this:
{assign var="module_js" value="/js/modules/{$module}.js"}
{if file_exists($module_js)}
<script type="text/javascript" src="{$module_js}"></script>
{/if}
Actually this has nothing to do with the Smarty-version. But the way you are assigning the variable is wrong. Try this way:
{assign var="module_js" value="js/`$module`.js"}
{if file_exists($module_js)}
<script type="text/javascript" src="{$module_js}"></script>
{/if}

I want to get items foreach, shuffle them and limit the output to 4 items.
i've this. (displays all items)
{content block_id=27}
{if $_content_27|count >0}
{foreach name=aussen item=box_data from=$_content_27}
<article class="news_row_article col-lg-3">
<div><img src="images/ImgResponsive_Placeholder.png" alt=""/></div>
<h3 class="news_row_headline">{$box_data.content_heading}</h3>
<p class="news_row_content">{$box_data.content_body}</p>
</article>
{/foreach}
{/if}
i've found this
{foreach array_rand($a_firm_display,5) as $i}
<img src="{$a_firm_display[$i].firm_logo}" />
{/foreach}
or this
Generate distinct smarty random numbers
{assign var="distinct_numbers" value=array_fill(1,15,'x')}
{assign var="distinct_numbers" value=array_keys($distinct_numbers)}
{assign var="x" value=shuffle($distinct_numbers)}
{* result *}
{foreach from=$distinct_numbers item="value"}
{$value} |
{/foreach}
hm..somehow get the items from $_content_27 put them into array, output, and limit them ?
any ideas ?
For older version of smarty I found very useful this snippet to shuffle my key => value array
{capture}{$items|#shuffle}{/capture}
Just place it before your foreach loop, I hope it helps somebody.
Maybe you can use shuffle and for instead of foreach, if you don't mind losing the array keys:
{$_content_27=$_content_27|#shuffle}
{for $iter=0 to 3}
...
{$_content_27.$iter.content_heading}
...
{/for}
I have an array that have duplicated values, I want to print the value only once no matter how many time it exist on the array.
This is the code that I have:
{foreach item="item" from=$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}
{$tagitem}
{/if}
{/foreach}
{/foreach}
I am not sure it works with all the versions.
Maybe it would be a bit cleaner to call an array_unique() in the php.
I have this smarty code :
{iterate from=fruits item=fruit}
....
{/iterate}
I want to have a counter inside this loop that accept a start value and increase by one until the loop continues.
I should i use? i am not good in smarty.
Thank you.
You can use the .iteration
{foreach from=fruits item=fruit}
current item #: {$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 {$smarty.foreach.counter.iteration}
{/foreach}
all im trying to do is to use the simple continue tag but it keeps giving me error like this:
string(145) "Smarty error: [in module_db_tpl:onlyimage4;image_detail line 26]: syntax error: unrecognized tag 'continue' (Smarty_Compiler.class.php, line 590)"
my code is as follow:
{foreach from=$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
*}
i have an associative array and i am trying to get the first record with smarty.
In php i use current(array), but smarty dont seems to have current.
So i wrote the code below
{if is_array($browseProducts.data) }
<ul class="products-grid">
{foreach from=$browseProducts.data item=item}
{assign var='image' value=''}
{if is_array($item.images) }
{php} $image=current($item.images); {/php}
{/if}
{/foreach}
</ul>
{/if}
in {php} section current($item.images) gives Warning: current() [function.current]: Passed variable is not an array or object
The syntax is right so i guess the $item.images from smarty can not be read by {php}
Any way to pass $item.images to {php} section, or what.
Any suggestion to solve my problem?
But what if the keys of the array are associative? You could alsdo do:
{$item.images|#current}
{$item.images.0}
should return the first element of the $item.images array.
So:
{if is_array($browseProducts.data) }
<ul class="products-grid">
{foreach from=$browseProducts.data item=item}
{assign var='image' value=''}
{if is_array($item.images) }
{$item.images.0}
{/if}
{/foreach}
</ul>
{/if}
