Trouble While Changing Language of Multi-language script - php

I made a multi-language website .
It contains only two languages : English and French.
The default language is English and the second language is French
English works perfectly in the website but French doesn't because while changing the language to French using the URL (?lang=fr) I get random letters (in this case I got 'F') and if I switch to (?lang=de) I got 'D') it means that I get to first letter of the varibale $_GET["lang"]
This is the code of my lang.php file
<?php
session_start();
if(isset($_GET['lang']))
{
$lang = $_GET['lang'];
$_SESSION['lang'] = $lang;
setcookie('lang', $lang, time() + (3600 * 24 * 30));
}
else if(isset($_SESSION['lang'])) {$lang = $_SESSION['lang'];}
else if(isset($_COOKIE['lang'])) {$lang = $_COOKIE['lang'];}
else {$lang = 'fr';}
if($lang=='fr'){$lang_dir = 'fr.php';}
else if ($lang=='en') {$lang_dir = 'en.php';}
else {$lang_dir = 'fr.php';}
include 'administration/includes/lang/'.$lang_dir;
?>

I can't set a php cookie

I made a php script that allows me to switch the language of my website and for that, I used a cookie called lang to store the user's language prefer but I don't Know why this cookie can't be set as I can't find it in the chrome developer tap .. Although I made this script also with session variable in case cookie isn't set, it doesn't work either, as it shifts the language whenever I change the page
this is my PHP script
<?php
session_start();
if(isset($_GET['lang'])) {
$lan = $_GET['lang'];
$_SESSION['lang'] = $lan;
setcookie("lang", $lan, time() + (3600 * 24 * 30), '/');
} else if (isset($_SESSION['lang'])) {
$lan = $_SESSION['lang'];
} else if (isset($_COOKIE['lang'])) {
$lan = $_COOKIE['lang'];
} else {
$lan = 'en';
}
include "languages/" . $lan . ".php";
?>
I have two files in that language folder en.php and ar.php and each one contains an array with translation like below
<?php
$lang = array(
"Give" => "Give",
"Blood" => "Blood",
"Register as a donator" => "Register as a donator",
"Search for a donator" => "Search for a donator"
I include my script in all my site's pages
here is my chrome developer tap screen shot
any thoughts?
Thanks for helping in advance :)

How to automatically reflect changes when adding PHP cookie?

My website by default is in English
But I can change the language, when a visitor visits our website with a url of a news item in Spanish:
example.com/es/news/718/url-title-article/
The url given as an example is a news in Spanish since the first folder or directory is named "es" example.com/es/news/718/url-title-article/ -> es
And, that's where the trick comes, since I have a function that allows me to obtain the name of the first folder or directory and if it matches with the given parameters, it should set a cookie with the language of that url, in this case Spanish -> "es".
if($FOLDER_LANG === "es" || $SUBDOMAIN_LANG === "es") {
setcookie ('language', 'es', time()+60*60*24*365, '/', 'example.com');
}
if(isset($_COOKIE['language'])){
if($_COOKIE['language']==='en'){
$WEBSITE_TITLE = " | WebSIte EN";
$LANG = 'en';
$language = "en";
}elseif($_COOKIE['language']==='es'){
$WEBSITE_TITLE = " | WebSite ES";
$LANG = 'es';
$language = "es";
}
} else {
$WEBSITE_TITLE = " | WebSite DEFAULT EN";
$LANG = 'en';
$language = "en";
}
But the problem, is that I have to reload the page to see the changes of the new language added to the site.
So how can you solve it without having to reload the site.
You need to write the logic which determines the language so it doesn't depend on the cookie.
So, before, where you might have had something like:
$language_data = get_i18n_data( $_COOKIES['language'] );
You would instead have something like:
function get_language() {
if($FOLDER_LANG === "es" || $SUBDOMAIN_LANG === "es") {
setcookie ('language', 'es', time()+60*60*24*365, '/', 'example.com');
return 'es'
}
return $_COOKIES['language'];
}
$language_data = get_i18n_data( get_language() );
The reason for refresh being needed is that $LANG and $language is set by an existing cookie and not the new one.
Analysing your code:
if($FOLDER_LANG === "es" || $SUBDOMAIN_LANG === "es") {
setcookie ('language', 'es', time()+60*60*24*365, '/', 'example.com');
}
Here, it's setting the cookie only in the header. It is not accessible until the page is reloaded.
One option is to add the following in the if condition:
$LANG = 'es';
$language = "es";
The rest of your code then reads existing cookies so this is what will load on the same page even if the cookie is set just before it:
A better way in my opinion is to keep it simple and expandable by using variable $language to drive the data:
$language = 'en'; //this is default
if(isset($_COOKIE['language'])){
$language = $_COOKIE['language'];
}
//now check if current $language is different to folder
if($FOLDER_LANG != $language || $SUBDOMAIN_LANG != $language) {
//this is condition depends on your variables. You might need && if both conditions should be met or modify as required
//set the language for this page (so no need for refresh and also set the cookie
$language = $FOLDER_LANG ? $FOLDER_LANG : $SUBDOMAIN_LANG; //sets to folder or sudomain language code if $FOLDER_LANG is empty. You can switch the two folders to priotorise the latter.
//now set the cookie
setcookie ('language', $language, time()+60*60*24*365, '/', 'example.com');
}
//now set the the title and the extra variable $LANG (you probably should choose one variable to use)
$WEBSITE_TITLE = " | WebSite . strtoupper($language)";
$LANG = $language;
Now you can support more languages and also won't need to refresh

PHP Session with a Language and Flat-File

Please excuse my English language skills.
I have a Homepage with a language exchange in the following included common.php
<?php
session_start();
header('Cache-control: private');
if(isSet($_GET['lang']))
{
$lang = $_GET['lang'];
$_SESSION['lang'] = $lang;
setcookie('lang', $lang, time() + (3600 * 24 * 30));
} else if(isSet($_SESSION['lang'])) {
$lang = $_SESSION['lang'];
} else if(isSet($_COOKIE['lang'])) {
$lang = $_COOKIE['lang'];
} else {
$lang = 'de';
}
switch ($lang) {
case 'en': $lang_file = 'lang.en.php'; break;
case 'de': $lang_file = 'lang.de.php'; break;
case 'ru': $lang_file = 'lang.ru.php'; break;
case 'fr': $lang_file = 'lang.fr.php'; break;
default: $lang_file = 'lang.de.php';
}
include_once 'lang/'.$lang_file;
?>
Now I would like to implement on my website a Mini-Blog with Flat Files and use the following Code
<?php
define("DEFAULT_LANGUAGE", "lang=de");
session_start();
$languages = ["de", "en", "fr", "ru"];
if( isset($_GET["lang"]) ){ $lang = filter_input(INPUT_GET, "lang", FILTER_SANITIZE_STRING);
if( !in_array($lang, $languages) ){ $lang = DEFAULT_LANGUAGE; }
$_SESSION["language"] = $lang;
}
function get_lang() { return isset($_SESSION["language"]) ? $_SESSION["language"] : DEFAULT_LANGUAGE; }
function get_post_names() {
static $_cache = [];
if(empty($_cache)){ $_cache = array_reverse(glob(__DIR__ . '/posts/' . get_lang() . '/*.php')); }
return $_cache;
}
function print_posts() { $paths = get_post_names();
foreach( $paths as $path ){ $content = file_get_contents($path);
echo "<div class='post'>\n";
echo "<p>{$content}</p>\n";
echo "</div>\n\n";
}
}
?>
<?php print_posts(); ?>
For the blog posts, there is a folder [posts] in which subfolders (de, en, fr, ru). In these subfolders there are, depending on the language, for example: "examplepost.php" in whose blog posts have been written.
The language selection works without any problems. But I want that when a user selects a different language, then the Blog automatically reads the voice corresponding folder of the blog and containing the outputs files.
The Problem is that there are two Sessions. This leads to errors! My question would be: How can I merge everything together in a Session or how can I connect the two Sessions without conflicts, so it works both (the language of the site and the output of the files in the folders of the visitors selected language for the Blog posts).
Many thanks in advance to all of you for your help and suggestions! Greeting
You do not need two sessions to hold the same variable ($lang).
What you can do is something like this:
session_start();
// check/set default language session
if (!isset($_SESSION["language"])) {
$_SESSION["language"] = DEFAULT_LANGUAGE;
}
if ($isset($_GET['lang']) && in_array($_GET['lang'], $languages) ){
$_SESSION["language"] = $_GET['lang'];
}
// execute more code
$lang_file = 'lang.'.$_SESSION["language"].'.php';
include_once 'lang/'.$lang_file;

I think I have expressed myself wrong.
The common.php for the language exchange, is responsible and should be retained. I just need a function in the common.php what are the same functions as in the other mentioned Script. It must be possible, that ...
is changed to the selected language on the website
And at the same time also referred to the sub-folder of the blog ("posts").
The Structure
[root]
|_ acp ........ admin-center
|_ css ........ css styles
|_ img ........ graphics
|_ inc ........ includes files
|_ func ....... function files (i.e. common.php)
|_ js ......... js files
|_ lang ....... language files
|_ posts ...... for the Blog Postings
|_ [de] [en] [fr] [ru]
In the last Folders are .php files witch, depending on the language selection has been selected via the common.php at the same time with the common.php also the files of the [posts] folder of the blog and displayed to be read.
In short ... 1) depending on the language in the language file redirect - AND - 2) in addition to the sub-folder of the [posts] folder and the contained files to be read and the contents of the files output.

Language problems (Cookie/Session)

I have problem with language on my page. When i choose one language it take it corectly, all content change, but when i reload or go to another page the language change back to default language, something with cookies are not corect :/. On localhost all works good but on hosting dont work.
Code:
<?php
session_start();
header('Cache-control: private');
if(isSet($_GET['lang']))
{
$lang = $_GET['lang'];
$_SESSION['lang'] = $lang;
session_set_cookie_params('lang', $lang, time() + (3600 * 24 * 30));
}
else if(isSet($_SESSION['lang']))
{
$lang = $_SESSION['lang'];
}
else if(isSet($_COOKIE['lang']))
{
$lang = $_COOKIE['lang'];
}
else
{
$lang = 'lv';
}
switch ($lang) {
case 'lv':
$lang_file = 'lv.php';
break;
case 'ru':
$lang_file = 'ru.php';
break;
default:
$lang_file = 'lv.php';
}
include_once 'lang/'.$lang_file;
?>
I suggest to check the answers here:
PHP Session data not being saved
Code that you showed us works well, so it must be a server/configuration issue. Good luck :)
Why are you using session_set_cookie_params and not setcookie?
Adding the ?lang parameter on every link is going to be tiresome. And bloat your code and make it less readable.

php Aruba $_session issue

I'm testing this code in Localhost and on Server "Aruba".
In local environment it works perfectly while on Server I dont have the expected session value
When I echo out the $_SESSION['lang'] it outputs :
-the correct country code (Ex.'en') in localhost
-On the Aruba server $_SESSION['lang'] outputs the array named $lang (that you can find on lang.en.php)instead of the needed country code!!
Where am I wrong?
thanks

my home.php
require_once('/web/htdocs/www.mywebsite.com/home/includes/langSwitcher.inc');

if(isset($_GET['lang']))
{

// register the session and set the cookie
$_SESSION['lang'] = $lang;
setcookie('lang', $lang, time() + (3600 * 24 * 30));

my lang.en.php
/*

*/
$langcode='en';
$lang = array();
$lang['PAGE_TITLE'] = 'pagetitle';
$lang['HEADER_TITLE'] = 'title header ';
$lang['SITE_NAME'] = 'name site';
$lang['HEADING'] = 'title';
It sounds like register_globals may be enabled (although that feature is deprecated). You can find out by running a phpinfo() and looking for the register_globals entry.
Assuming it is enabled, the only solution is to fix it in php.ini (you cannot override register_globals with an ini_set() call).
Well you are using $lang to keep the langcode, but also to store the array information. Perhaps in the langSwitcher.inc you should be using $langcode to store the session?
Because you are also settings the $lang var in the session their. On your server it seems to be using a reference to the $lang file, and therefor outputting the latest content set to $lang (which is the array) and on local it is storing the actual content of $lang.
Anyway, it can be solved by not using the same variable name to store two different items.
