Change default language programmatically?

[Ravingmad]

Hello,

I saw this tutorial about changing the default currency using a popup. I bought the module and I'm now trying to change the code to change the default language instead.

Could someone help me modify the code to adapt it to my need?

 

Thanks.

Which module are you using? It's really hard to guide you without seeing any code

I linked to the tutorial in my first post. I'm using PopUp Pro. And I'm using this tutorial :

 

https://mypresta.eu/en/art/developer/responsive-popup-with-currency-selection.html

 

I tried switching "setCurrency" to "countries" and to "setLanguage" and neither worked. I also tried this : 

     $id_lang=(int)Tools::getValue('id_lang');
    $default_lang =Configuration::updateValue('PS_LANG_DEFAULT',$id_lang);

And it didn't work.

 

I also tried changing the language cookie but for some reason when I type in "cookie->" the ">" changes into ">" in the Popup Pro module so I couldn't change the cookie.

 

The code that I'm trying to edit changes the currency perfectly but I'm trying to modify it to do the same to language.

 

The code in question : 

 

 

<h2 style="text-align: center;">Select your currency</h2>
<ul class="popupcurrencies">
<li onclick="setCurrency(1); $.closeOverlay();"><a rel="nofollow" title="Pound (GBP)">(GBP)<br />Pound</a></li>
<li onclick="setCurrency(2); $.closeOverlay();"><a rel="nofollow" title="Z�oty (PLN)">(PLN) <br />Z�oty</a></li>
<li onclick="setCurrency(3); $.closeOverlay();"><a rel="nofollow" title="Euro (EUR)">(EUR) <br />Euro</a></li>
<li onclick="setCurrency(4); $.closeOverlay();"><a rel="nofollow" title="Dollar (USD)">(USD) <br />Dollar</a></li>
</ul>
<style>
.popupcurrencies {
list-style:none;
margin:auto;
display:block;
min-width:450px;
clear:both; overflow:hidden;
}
.popupcurrencies li a {
display:inline-block;
background: #FE5F55;
color:#F0B67F;
font-size:14px;
font-weight:bold;
text-align:center;
padding:20px;
border-radius:4px;
width:100px;
float:left;
margin:5px;
cursor:pointer;
}
 
.popupcurrencies li a:hover {
background:#FF8077;
}
</style>

And by the way. By "didn't work" I mean it literally didn't do anything. Clicking the button didn't even close the overlay.
