PHP - Please Help With Language Session

I'm making a simple login system with MySQL and PHP (very simple, I'm just starting with PHP). The MySQL portion is done, but I need to ensure only people who are logged in can see certain content.

To check if people are logged in, my website checks that they have the $_SESSION['user'] variable set. If it is set, then it lets them continue through the website, if not, it tells them to login. Is that enough security, or can people simply inject a session cookie into their browser to spoof that they are logged in?

My idea was to generate a session key cookie when they login (just a random string of letters and numbers) and store that in the database, then on every page, check to make sure their session key is the same thing that's in the database. Is this necessary? It seems expensive.

hi everyone.

i'm wondering what the best way is to create a session variable and pass it to an iframe.
i need to do something along these lines, but it doesn't seem to pass the ID. Any hints on how i should accomplish this?

Code: [Select]
session_start();
  $_SESSION['ID']=$_GET['ID']; // id from previous page
$ID=session_id();

 <iframe src="iframepage.php?ID=<?php echo $ID; ?>" style="width:680px; height:200px;" noresize="noresize" frameborder="0" border="0" scrolling="Yes" allowtransparency="true" /> </iframe>

Hi! I want to have a first page on my website where you as visitor can choose the preferred language. No login at all.
I want to save this choice in a cookie or something. The easiest way
So next time he/she visits, the language choice is already made for he/she.

Any good suggestions for a php code that works?

are all languages possible to be inserted into database and be retrieved directly??

eg: write down the japanese words in the textbox and INSERT those into table and retrieve it using mysql_fetch_array()

Is that as simple as that, or i have to modify certain script...for certain language?
thanks

Hello,

I am currently making a small website that requires two languages. This is the class I made:

Code: [Select]
<?php

class languages {
  public function __construct() {
    if(!isset($_SESSION['language'])) {
      $_SESSION['language'] = 'nl';
    }

    $lang = isset($_GET['lang']) ? $_GET['lang'] : "";
    $languages = array('en', 'nl');

    if(in_array($lang, $languages)) {
      $_SESSION['language'] = $lang;
    }
  }
}

$languages = new languages;

$language = $_SESSION['language'];

?>
Now as soon I use index.php?lang=en, the website will display it self in English but, as soon I remove the &lang=en from the URI, the language gets not stored in the session and it displays nl agian.

Can somebody help me?

Thank you!

Hi again PHP Freaks. So I would like to code something similar to the buy menu of Counter-strike: Global offensive in-game module, just in a browser and for a project of mine. I've made the design in photoshop to illustrate better. I just don't know what I should look into to make this kind of menu, I would love if someone could explain me what languages that this would require. (I'm guessing HTML, CSS and jQuery but I am not sure) more specific help like which particular codes would be much appreciated.   Here is a picture of what I would like to create. (Also attached) http://i1227.photobu...zps4195288a.png   Attached Files  CSGOKeyz.png   149.81KB   0 downloads

At the minute i am using variables in my tpl files in place of plain text so users can change the language the page is shown in. eg. the tpl file would include:
$lang->hello;
and the replacement would be
$lang['hello'] = 'hello';
the php file would include the language class which replaces the variable in the language file with the array value in the relevant language file.
but what happens when i have a phrase with a needed variable in the middle?
$lang['msgs'] = 'you have '.$msgs.' messages';
i cant have 'you have' and 'messages' as seperate lang variables as phrases are constructed differently in other languages? so how do i accomplish this? hopefully i habe explained this ok.

what's the best way to have a website in 2 languages?
I already have the website duplicated in the 2nd language but I'm thinking on the best way to do the language change.

should I just append variables to the URL when clicking on the flag icon on each page to change to the 2nd language?

any other ideas??

I came across usage of ^= in one the password hashing codes and am trying to find what this operator means in PHP.

I have textfield for signature in my form, I m checking if the signature was sent ( if(!empty($_POST['signature']))   
and if it's not empty I m putting it into the db.

The problem is that, I have noticed a greek user has entered something in greek letters, and function could not deal with it and saved it as it is.( DB field supports greek charset )

I just want to allow english and german chars with special chars ( ",',< etc. ) , no other charset like greek.
How can I do that? any function for this purpose ?

I got site wirch I like tu turn to multilanguage.
Code: [Select]
<?=$home_jezik?>This is my variable for language code. So I wonna add it to
Code: [Select]
<?php echo $redak['novost_naslov_hr']; ?>so that  "hr" change to "en" or any other language. I try with this but nothing happens
Code: [Select]
<?php echo $redak['novost_naslov_.$home_jezik']; ?>

Hello,

I will tell you whant I want to do first and what I've done so far and hopefuly someone will be able to help.

What I hope for is to have one unique index.php that will work everywhere.  I don't mind if I have to modify each and add path where it is located since this won't happen often.

It needs to take car of preferred language and if someone land in a directory, I want it to load the index.php there.

I also look to not expose hidden URL in the browser URL box.  See *note 1 below.

My directory structure is as follow:

/index.php
/about/index.php
/blahblah/index.php

The current index.php I'm trying to build looks like this:

<?php
    if (preg_match('/^www.(.+)$/i', $_SERVER['HTTP_HOST'], $matches)) {
      header("Status: 301 Move permanently", false, 301);
      header('Location: http://'.$matches[1].$_SERVER['REQUEST_URI']);
      exit;
    }

    session_start();
    $Lang = $_SESSION['lang'];
    
    if (!isset($Lang))
         {
        if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE']))
            {
            $Lang = explode(",",$_SERVER['HTTP_ACCEPT_LANGUAGE']);
            $Lang = strtolower(substr(chop($Lang[0]),0,2));
            if ($Lang !== 'fr' && $Lang !== 'en')
                { 
                $Lang = "en";
                }
            }
        else
            {
      $Lang = "en";
            }
        $_SESSION['lang'] = $Lang;
        }

    include $_SERVER["DOCUMENT_ROOT"] . ("/index_" . $_SESSION['lang'] . ".php");
?>

First I remove "www." in the address when applies.  Not a must but I like that.

Then I check if Language is already set, if not I detect and set it for next pages.

I finally load the proper page according to language with an "include" so index_en.php remain secret (sort of).

*note 1: all my index_xx.php pages in every directory have this: Code: [Select]
<script language="javascript" type="text/javascript">
        if (self == top)
        top.location.href="directory/index.php";
    </script>

When in the root, it seems to work and I get the proper page but if I place this in /about/ then when I tried to load /about/index.php it doesn't work.  I think the include on the last line could be the problem.

I'm either close or far from it, I don't know.

Thank you.

According to woorank.com my page shows the following.


Language
    Declared: Missing
    Detected: en

I have used Code: [Select]
header('content-type: text/html; charset=utf-8');
but do not know how I declare the language.

also how do i specify Language/character encoding

how is this done ?
