    bot spammer verification system

    in PHP Coding Help

    Posted

    Back into php after about 6 months, trying to re learn alot, started making a quick program that just creates a random math problem, addition or multiplication with numbers 1-9 to verify wether it's a bot or not. So far I've got it generating random math problems with those variables as seen here:

    http://74.70.230.229/verification/verify.php

     

    Now I know I can make it so they must enter the answer and have it verify it, except for the part where I'm trying to figure out the answer to the question myself! In order to display the images for the numbers, I made the variable $keyone equal to images/filename.gif. Now I'm trying to convert it back to the number and then do the math, with horrible failure, wondering if anyone could give any advice.

     

    Before you look at the code, I know it is EXTREMELY inefficient and awful, just something to get me back into the programming mindset.

     

    Code:

    <?php

function randkey($length)
{
  $pattern = "123456789";
  for($i=0;$i<$length;$i++)
  {
   if(isset($key))
     $key .= $pattern{rand(0,9)};
   else
     $key = $pattern{rand(0,};
  }
  return $key;
}

$keyone = randkey(1);
$keytwo = randkey(1);

// determine if its + or *
$func_id = rand(0,1);
if ($func_id==0)
{
	$function = "+";
	$function = "images/plus.gif";
} else {
	$function = "*";
	$function = "images/multiply.gif";
}
// end of + or *

// convert the number into the number image
if ($keyone=="1")
{	
	$keyone = "images/one.gif";
} elseif ($keyone=="2")
{	$keyone = "images/two.gif";
} elseif ($keyone=="3")
{	$keyone = "images/three.gif";
} elseif ($keyone=="4")
{	$keyone = "images/four.gif";
} elseif ($keyone=="5")
{ 	$keyone = "images/five.gif";
} elseif ($keyone=="6")
{	$keyone = "images/six.gif";
} elseif ($keyone=="7")
{	$keyone = "images/seven.gif";
} elseif ($keyone=="8")
{	$keyone = "images/eight.gif";
} elseif ($keyone=="9")
{ 	$keyone = "images/nine.gif";
}

if ($keytwo=="1")
{	
	$keytwo = "images/one.gif";
} elseif ($keytwo=="2")
{	$keytwo = "images/two.gif";
} elseif ($keytwo=="3")
{	$keytwo = "images/three.gif";
} elseif ($keytwo=="4")
{	$keytwo = "images/four.gif";
} elseif ($keytwo=="5")
{ 	$keytwo = "images/five.gif";
} elseif ($keytwo=="6")
{	$keytwo = "images/six.gif";
} elseif ($keytwo=="7")
{	$keytwo = "images/seven.gif";
} elseif ($keytwo=="8")
{	$keytwo = "images/eight.gif";
} elseif ($keytwo=="9")
{ 	$keytwo = "images/nine.gif";
}
// end of number to number image conversion

// display in image the problem - x (+or*) x
echo "<img src=\"$keyone\"> <img src=\"$function\"> <img src=\"$keytwo\"> <br />";
	// end of display

    registration script

    My registration script is only showing one error if there is one or more errors.

    this is the script, thanks for any help you can provide:
    [code]
    <?php
    define("IN_OMEGA", true);
    $omega_root_path = "./";
    include($omega_root_path."base.php");

    if (isset($_POST['submit']))
    {
    $username = htmlspecialchars(trim($_POST['username']));
    $password = md5(crypt(htmlspecialchars(trim($_POST['password'])), strlen($_POST['password'])));
    $confpass = md5(crypt(htmlspecialchars(trim($_POST['confpass'])), strlen($_POST['confpass'])));
    $email = htmlspecialchars(trim($_POST['email']));

    $errors = array();

    if (empty($username))
    {
    $errors[] = "Username field is empty";
    } elseif (empty($password))
    {
    $errors[] = "Password field is empty";
    } elseif ($password!=$confpass)
    {
    $errors[] = "Passwords do not match";
    } elseif (empty($email))
    {
    $errors[] = "E-Mail Address field is empty";
    }


    $error_count = sizeof($errors);
    $error_phrase = (($error_count)==1) ? "<strong>There was a problem with your registration attempt:</strong><br />" : "<strong>There were some problems with your registration attempt:</strong><br />";

    if (($error_count)==0)
    {
    $create_user = sql_query("INSERT INTO " . USERS_TABLE . " (`user_groupid`, `username`, `password`, `email`, `login_key`, `reg_date`, `reg_ip`, `user_lastactivity`) VALUES ('" . $sitedata['default_ugid'] . "', '" . $username . "', '" . $password . "', '" . $email . "', '" . crypt($username, rand(15,3648)) . "', '" . mktime() . "', '" . $_SERVER['REMOTE_ADDR'] . "', '" . mktime() . "')");
    } else {
    echo $error_phrase;
    foreach ($errors as $error)
    {
    echo "-" . $error . "<br />";
    }
    }
    }

    $template = new template("templates/" . $sitedata['template_dir'] . "/register.tpl");
    $template->output();

    Using strotupper() not working?

    in PHP Coding Help

    Posted

    I was hoping someone could help me out with this, it is pretty self-explanatory.

    [code]
    $sentence = "i wanna make the beginning letter capital only.";

    // $words is now an array
    $words = explode(" ", $sentence);

    foreach ($words as $word)
    {
    $word = strtoupper(substr($word, 1, 1));
    echo $word;
    }
    [/code]

    This outputs:
    AAHEEAN

    Thanks for any help you can give.

    obfuscate html with php function?

    in PHP Coding Help

    Posted

    Basically, I know there are tons of free things where you put in your html and it encodes it with javascript so it still works but makes it ridiculously difficult for others to edit. Well...I need this to work with a php function, so I can do encodehtml($input); and have it return the input encoded.

    Any help? Thanks!

    simple function not working?

    in PHP Coding Help

    Posted

    i am using a dateline, so for making registered date, the regdate is mktime();

    i can easily decode it by putting date("dateformat", $dateline);

    so i am making a function to decode the time in my format...not sure why its not working, probably something simple.

    [code=php:0]
    function decodeTime($dateline)
    {
    date("m-d-Y h:i A", $dateline);
    return $dateline;
    }
    [/code]

    any ideas?

    I have an administration panel coded by the wonderful Adrian, only, when it redirects to another location, it only redirects the right frame! I have tried using header location, window.location, document.location. No matter what it will always redirect the main frame there, and leave the left frame! Can anyone help? I don't think this requires you to see the frame script, but if you think it would help, ask and I will show it.

    well right now i have it so on registration it creates a random number 1-9999999 and then md5's it. that is their loginkey, the cookie that is created, its content is userid-loginkey, so like '213-f761938942d1c06c9fb4b2d1644d147f'

    Do you think this is secure enough?

    encrypting cookies....

    in PHP Coding Help

    right now on my website, if you have a cookie editor, you can edit the user_name cookie from any username, to any username and act like anyone! I need to know how I can encrypt it so the user won't be able to change it without it messing up the cookie entirely. but I need it so I can decrypt it so I can display the username, unless there is another way?

    Please post back.
