Hi!

Lets say I got an php-array:

$lang['nl'] = 'dutch';
$lang['en'] = 'english';
.. etc .. you get the picture..

next thing is looping through those values:

{foreach from=$lang.languages key=k item=v}
language: {$v} <input type="text" name="value_{$k}" value="{$value_$k}">
{/foreach}

getting this result:
<input type="text" name="value_nl" value="{$value_nl}">
<input type="text" name="value_eng" value="{$value_en}">

cause {$value_nl} and {$value_en} wil hold some content... any ideas howto make a var like {$value_[nl|eng]} ?

thanks!

The standard SMARTY syntax does not allow this. But I have written a modifier varvar which does solve the problem.

Your will find it in the middle of this thread http://www.phpinsider.com/smarty-forum/viewtopic.php?t=12678&start=0

u.tews,

it looks great, but i just doesn't work

if I post my form, the value's of it are automaticly assign into smarty again.
I checked the values in the debug console, so no doubt that the values are actually there.

but it just wont return the value...

the modifier receives the $string correct, but somehow when return it cant find that value in the tpl-vars array...

assign the value_nl/en in tpl or php also wont do the job.

weird :S

If you have
$lang['nl'] = 'dutch';
$lang['en'] = 'english';
as array your {foreach} loop is wrong.

[RGordijn]

haha thats true.
I made a mistake, $lang is just a HUGE array with alle the 'language', en i got:

$lang['languages']['nl'] = 'dutch';
$lang['languages']['en'] = 'english';

So my foreach works perfect. it's just that I cant get to the darn value

Just another question: Caching is disabled?

Did you check with {debug} if there is a variable value_nl and value_en?

[RGordijn]

caching, nope. i didn't create the directory and didn;t told smarty to use it.

( while I'm typing this, I thinkin' about turning it on.. )

and debug, yes. I qoute:

[U.Tews]

Caching must stay off. As i said the {foreach} is working here.

[RGordijn]

foreach is working o.k.
but i still didn't get it to work properly.

but! i got a solution that also works

<input type="text" name="value[{$k}]" value="{$value[$k]}">

just make a html array with value[] and $k, and I'm done!

lol, to easy, thanks anyway!
