Change Language based on selected Currency

[nimonogi]

Hello,

 

Any help will be greatly appreciated...

 

I want the following form to change both language and currency when user change the selected currency.

 

Original form - changes currency:

<form method="post" action="{php}echo $_SERVER["REQUEST_URI"];{/php}">
 <p class="header">{$LANG.choosecurrency}</p>
 <p>
 <select name="currency" onchange="submit()">{foreach from=$currencies item=curr}
<option value="{$curr.id}"{if $curr.id eq $smarty.session.currency} selected{/if}>{$curr.code}</option>
{/foreach}</select>
   <input type="submit" value="{$LANG.go}" />
  </p>
</form>

 

 

Modified form - changes currency and language - not working:

<form method="post" action="{php}echo $_SERVER["REQUEST_URI"];{/php}">
 <p class="header">{$LANG.choosecurrency}</p>
 <p>
 <select name="currency" onchange="submit()">{foreach from=$currencies item=curr}
<option value="{$curr.id}&language=lang{$curr.id}"{if $curr.id eq $smarty.session.currency} selected{/if}>{$curr.code}</option>
{/foreach}</select>
   <input type="submit" value="{$LANG.go}" />
  </p>
</form>

Expected result: "?currency=2&language=lang2"

Any ideas on how to do this?

 

Needed files are already created and working fine when i'm visiting "domain.com/?currency=2&language=lang2".

 

Thanks.

I have found this solution which is working:

<select name="currency" onchange="window.location.href='?currency='+this.options[this.selectedIndex].value+'&language=lang'+this.options[this.selectedIndex].value;">

Any suggestion/comment?
