Making an Ajax request for one little label maybe a bit overkill.
As i understand you request the whole form through an Ajax request.
And display this to the user? And every language generates a new form?

Why not just create the form dynamically with javascript and load the
data from PHP. So the form can stay the same for all calls. You just
fill it with data depending on the language selected. You can fill the
form for instance by sending a JSON encoded object from PHP to
javascript.

attached mail follows:

you understood right.

basically my problem is that the layout avoid it.
here is "something like" my layout :

<div#0>
<div#1>Lanague (label) : <img flag> <img arrow to show all languages from
div#2></div#1>
<div#2> all flags</div#2>
<div#3> login field + pwd field + submit button</div#3>
</div#0>

till now i only use AJAX to refresh the content of div#3
but it does not change the label from div#1 when user selects another
language from div#2.

if i place the whole form into a PHP i face several questions :
- how the ajax will reload this PHP page (reloading itself) in the parent
control div#0 ?
- when user will click on submit button, where will be loaded the content
return of checking if log+pwd are correct ?
- how to redirect to another PHP page, when user click on submit button ?
the redirection will happen only in the content div, so only in div#0 and
not into the browser :-(

Well it looks like you need a extra Ajax call to the server.

Click a language flag sends a request to the server. The server
responds with an JSON object. Containing the content for <div#2>. With
javascript you can update the contents of <div#2>

If you would like to reload the whole of <div#0> You could send and
JSON object from PHP to javascript. And let javascript generate the
div structure and update the DOM.

> return of checking if log+pwd are correct ?

When a user logs in a Ajax request is send to the server. the server
responds with an JSON object containing the error message. With
javascript you could update the contents of <div#3> to display a
message.

I have a hard time understanding this last issue. What exactly do you
mean by redirecting to another PHP page?

attached mail follows:

in fact i meant by redirecting the following thing :
- if user wrote a correct pwd and login, the system should redirect [using
header("Location .... ] syntax to launch the application.
but if i use such syntax it will be redirected only into the div#0, and not
in the browser itslef.

is it clearer now ?

It's crystal clear :)

I guess you could do it in two ways. Firstly without a redirect. You
could just use javascript and CSS to show some sort of error message.
Reload the form in the div. And give the user another try to login.

If you really want a reload. You have to do it with javascript. You
could let PHP send back a status to javascript. And based on that.
Either load a div with content. Or do a document.location = ''; Hope
it helps.

Hi Alain,
You can create a mini-db with XML, that contains translations for each of
the words you need (if there are 10 words, 50 langs, you got 500 records..
small and useful).

HTH,
Nitsan

I am in a bit of a pickle, or is that PECL?

I need to use either mime_content_type or FileInfo to get the mime type
of a file that is dumped into the system via email.

Now that is the easy part, where the hard part comes in is that a
commercial host that I use will do neither reason being that
mime_content_type is deprecated, and that FileInfo is "unstable" in PECL
only :/

Anyone got a workaround on this? I *really* don't feel like writing a
zillion lines of code to get arbitrary mimetypes out that will only be
used a little while and to replace 1 and 2 lines of code respectively.

attached mail follows:

I added var_dump($result); to the function.

As part of the output I get the following:

["fields"]=> array(1) { ["fa"]=> string(22) "ÙˆØ±ÙˆØ¯ Ø¨Ù‡ Ø³Ø§ÛŒØª"}

which is the string which should be returned and printed.

The result is there, however, it couldn't be printed.

Any ideas?

Hello,

with the following call I try to print a string out of DB

echo $allg->translate($db, $lang, 14, "auth/authCallback", 4);

function translate () should do a DB querry and returns the requested

no value.

Here is the function:

function translate ($db, $lang, $MaiKey, $page, $pid) {

$statement = "SELECT fa FROM language WHERE MaiKey='$MaiKey' AND
page='$page' AND pid='$pid'";

$result = $db->Execute($statement);

if ($result=== false) die();

return $result->fields[0];
}

Could anybody see what is going wrong here?

its hard to say, since we cant see whats going on inside the Execute
function... you might try to add a
var_dump($result);
directly after the call to Execute, just for debugging purposes, then remove
it once you know whats going on.

Try $result->fields["fa"] instead.

Hi Everyone,

Last week you all helped me with the code to pull the database field
names directly from the database rather then being hardcoded by me.
Now I got to thinking, that I have exposed my database layout to
anyone who can log in and see it. Is that a security issue? I've heard
that if an attacker has the field names of a database, it makes it
easier for them to try and inject code into it. All my queries to the
database are done through prepared statements, and
mysqli_real_escape_string. So I've taken care of at least part of it.

I'm thinking that sense you have to log into the website to see the
field names, it's okay as long as I trust and monitor my users. But I
thought I would pose the question to people who are ALOT more
knowledgeable then me :)

Any comments are welcome, if you want to see source let me know and I
can shoot you an e-mail off list (Don't really want to expose my code
to all the archives just yet :))

As long as you're taking the necessary measures to ensure that your
database is not breakable/hackable, then us knowing your schema
shouldn't be an issue. I'd bet that one could guess part (or all?) of
many people's database schemas b/c they're so generic - and it doesn't
really matter to obfuscate them. I don't think it's as important to
create obscure database schemas as it is protect how you interact with
it.

However, just make sure of the following, and you should be good:

• Use mysql?_real_escape_string as you mentioned
• Use `backticks` around ALL your table and field names:

<?php
$user_id = mysql_real_escape_string ($_GET['user_id']);
$sql = "SELECT `first_name`, `last_name` FROM `user` WHERE (`user_id`
= '$user_id')";
?>

With those simple precautions, you should be well-protected.

HTH,
~Philip

I fixed this last time by looking for white space both before and
after the opening and closing php tags, as a Google search had
revealed. But this time, I've spent an hour running down various
files and not seeing what the heck is wrong. Here's the essential
setup.

main.php
<?

require_once 'shared_style.php';
require_once 'something.php'

shared_style.php
<style>

a.friend_selector_tabs:hover {
background: #E4E4F8 none repeat scroll 0%;
}

.title_msg {
        font-size: 14px;
        color: #444444;
        font-weight:bold;
}

</style>

The something.php has a setcookie call on the line number that PHP is
complaining about for headers. What am I doing wrong that's causing
even mire headers to be generated? I tried moving the require_once
'something.php' above, but no luck there either.

Thanks for any help,
Waynn

If something.php is setting cookies and such, it has to be above
shared_style.php. If you've already tried that with no success, post
the code of something.php for us to view.

it is sometimes a good idea to put error_reporting(0);
just a suggestion ;)

this also should not be an issue if you have output buffering turned on.

PHP is great, it will make sure to send the headers *first* then.

but yes, whitespace sucks as well. it makes IE's CSS flake out weird
sometimes. there's multiple reasons to write clean code :)

This is for a facebook app, so it's just

  public function set_user($user, $session_key, $expires=null) {
    if (!$this->in_fb_canvas() && (!isset($_COOKIE[$this->api_key . '_user'])
                                   || $_COOKIE[$this->api_key .
'_user'] != $user)) {
      $cookies = array();
      $cookies['user'] = $user;
      $cookies['session_key'] = $session_key;
      $sig = self::generate_sig($cookies, $this->secret);
      foreach ($cookies as $name => $val) {
        setcookie($this->api_key . '_' . $name, $val, (int)$expires);
        $_COOKIE[$this->api_key . '_' . $name] = $val;
      }
      setcookie($this->api_key, $sig, (int)$expires);
      $_COOKIE[$this->api_key] = $sig;
    }
    $this->user = $user;
    $this->api_client->session_key = $session_key;
  }

But the problem is I can't tell where it's being called. Is there any
way to generate a stack trace from the error logs so I know what the
calling function is?

Actually, I think I fixed it by moving the style sheets below the
instantiation of the facebook client, where I *think* set_user was
being called. I'm still curious if it's possible to get stack trace
information on errors, though. :)

Hi Everyone,

I have a client that wants me to fork a current project into a
membership management piece of software. Does anyone know of any open
source projects that I can look at?
The big things I need, are the ability to decide if the members will
receive a paper copy of a newsletter vs. a e-mail copy. Ability to
export addresses for paper mailing a newsletter.
Possibility to store seasonal addresses for the same person (Up here
in the Great white north we call them "Snow Birds")
PHP/MySQL based since that's what I know :)

I've done some googling but keep seeming to find club's where I can
become a member... Which is not what I want :)

There are many, many membership management programs out there, though
I doubt that there are any open source ones. It is a lucrative
business for many-a-folk.

I have always advised prospective clients to buy, not build, as the
commercial software choices out there are many and very good. There
are many tricks and traps to trying to build one from scratch, among
them building a combined cycle and on-demand billing system.

One place to look is the Society of Non-profit Executives, or improve
