php Password Randomizer . . . - cortexaz - 12-19-2009
Hello Folks,
I really really need your help . . .
I'm installing the flash xml gallery on my web site, but I want that only certain group of people had access to the files, who share the certain kind of information among each other . . .
So I need the php script that protects the web access with passwords that will change automaticly at every access . . . I mean that when you access the web site there will be a question and the answer will be the password . . . And this question/answer will change randomly at every access . . .
Does anyone know where I can get that script?
Thanks in advance . . .
I count on your help . . .

I didn't look too closely, but, try this? http://www.hotscripts.com/listing/random-password-generator-53972/
RE: php Password Randomizer . . . - Gaijin - 12-19-2009
PHP Code:
<?php
if(isset($_POST['submit'])) {
if(md5($_POST['answer'] == $_POST['check'])) {
// log in the user
}
}else{
$questions = array(
0 => 'First question',
1 => 'second and just keep adding as much you want',
);
$answers = array(
0 => 'pass for the first question',
1 => 'pass for the second question',
);
$c = count($access);
$i = (rand(0, $c) -1);
foreach($questions as $id => $question) {
if($id == i) {
echo $question;
echo"<input type=\"hidden\" name=\"check\" value=\"".md5($answers[$i])."\" />";
echo"<input type=\"text\" name=\"answer\" />";
}
}
}

Thanks very much . . .
I didn't understand cause I'm newbie but thanks anyway for your time and attention . . .
RE: php Password Randomizer . . . - Gaijin - 12-19-2009
Well you just need to update $questions and $answers with your questions and passes.
If I could see a script that you're using I could code the above one to match your settings.

Please paste in future your code within [ code ][ /code ] or [ php ][/ php ] tags(without whitespaces)
Here is the updated code, this code takes a question from $LOGIN_QUESTION randomly and prints it to the screen,
the questions are in order with the $LOGIN_INFORMATION array
First member of $LOGIN_QUESTION is for first member of $LOGIN_INFORMATION, the password is saved as md5 hash in a hidden input field and on login the inputed password is checked with this hash.
You will need to input username and password based on the Question.

NP and don't worry you've fixed it!
Sorry the code was not printing a Question string..
I've updated the above post, look for the line "echo $info".
RE: php Password Randomizer . . . - cortexaz - 12-21-2009
Thanks . . .
I've changed it . . . I know it's too much
, but I'll ask one more question concerning IE8 . . . I've inserted the image in php code, but IE8 doesn't show . . . Have you ever had such kind of a problem??Thanks for help . . .
If there's anything I can do in return I'm ready . . . Do you work as a webmaster? Or it's just a hobby?
