I'm looking for a file, its name is server-side-script.php, so I searched it seems to be a standard translation file, I did not quite understand it.
The question is that I have a script and it comes with 2 languages, and for me to add 1 more language I would need to put the line in the header indicating the new language and create a file for the language, example "pt.php".
I added the line and the file and it does not find the file pt.php, it is as if this file had been set in some page, and the action of this form indicates that file server-side-script.php that I can not find nowhere. Does anyone know anything about it?
Div with the line I needed to add.
<div id="country-select">
<form action="server-side-script.php">
<select id="country-options" name="country-options">
<option <?php if($lang == 'en'){ echo "selected='selected'"; }?> title="<?php echo addURLParameter($_SERVER['REQUEST_URI'], 'lang', 'en'); ?>" id="en" value="en">EN</option>
<option <?php if($lang == 'ru'){ echo "selected='selected'"; }?> title="<?php echo addURLParameter($_SERVER['REQUEST_URI'], 'lang', 'ru'); ?>" id="ru" value="ru">RU</option>
<option <?php if($lang == 'pt'){ echo "selected='selected'"; }?> title="<?php echo addURLParameter($_SERVER['REQUEST_URI'], 'lang', 'pt'); ?>" id="pt" value="pt">PT</option>
</select>
<input value="Select" type="submit" />
</form>
</div>
