Need help with Registration Script

Skewled · August 12, 2010

I've only modified the code below for the query, I just removed that to make it shorter, the query works fine. I've added human verification to the script and it displays the image and numbers fine, I also echo'd out the variables and they match using SHA1(). My captcha script is displaying the image properly and sets the $_SESSION['pass_phrase'] variable fine.

It isn't throwing any errors or creating the account.

As of right now I have a headache and figured I could use some help here. Let me know if you spot the error.

<?php
  error_reporting(E_ALL);
  require_once('cons.php');
   // Get the variable sent by AJAX script if it is typed in
  // Connect to the database

if (isset($_REQUEST['username'])) {
$ok = 'okay';
$den = 'denied';

   // Secure the information
$passname = mysqli_real_escape_string($dbc, trim($_REQUEST['username']));
   // Lookup the username in the database
      $query = "SELECT username FROM info WHERE username = '$passname'";
      $data = mysqli_query($dbc, $query);
   // Allow some time to get the response
 sleep(3);
   // If 1 is returned that name exsists, if 0 then we can move forward
      if (mysqli_num_rows($data) == 0) {
   // Send okay back to the ajax script so it knows to stop bothering the user
echo $ok;
return $ok;
} else {
   // Send denied back to the ajax script so the user knows that name is taken
echo $den;
return $den;
} // Close If / Else statement
  } // Close (isset($_REQUEST['username'])) {

  // Start of Main Submit Function Script
   session_start();
  require_once('aprs.php');

Hoping today will breath new life into this post and hopefully someone will be able to spot the error.

hcdarkmage · August 13, 2010

For one thing, your session_start() should be right after the opening php tag.

Skewled · August 13, 2010

I moved it to the correct place, and still have the same troubles.

jcbones · August 14, 2010

The part I think is the problem is:

// The username is unique, so insert the data into the database
$hash = md5( rand(0,1000) );
        $query = "INSERT INTO";
        mysqli_query($dbc, $query);

More specifically,

$query = "INSERT INTO";
        mysqli_query($dbc, $query);

I think you need to add more to your query than "INSERT INTO". MySQL is like a woman, it wants you to spell it out word for word.

Skewled · August 14, 2010

I noted above in my original post that the query worked fine, I removed the query from the code to save some space.

PFMaBiSmAd · August 14, 2010

If you don't post the actual code responsible for the symptom, no one can help you with your actual code.

LOL -

// Allow some time to get the response
sleep(3);

^^^ Computer programs don't work that way. All that does is make it take longer for the code on the page to execute.

Skewled · August 14, 2010

I've posted all the code that is relevant to the problem.

The only thing that may be causing a further issue is the captcha script I'll post that below.

Outside of that the query isn't the issue, prior to adding the CAPTCHA check and the AJAX code everything worked just fine. The query doesn't need any information from either of the new additions.

<?php
  session_start();

  // Set some important CAPTCHA constants
  define('CAPTCHA_NUMCHARS', 6);  // number of characters in pass-phrase
  define('CAPTCHA_WIDTH', 115);   // width of image
  define('CAPTCHA_HEIGHT', 25);   // height of image

  // Generate the random pass-phrase
  $pass_phrase = "";
  for ($i = 0; $i < CAPTCHA_NUMCHARS; $i++) {
    $pass_phrase .= chr(rand(97, 122)); 
}

  // Store the encrypted pass-phrase in a session variable
  $_SESSION['pass_phrase'] = SHA1($pass_phrase);

  // Create the image  
  $img = imagecreatetruecolor(CAPTCHA_WIDTH, CAPTCHA_HEIGHT);  

  // Set a white background with black text and gray graphics  
  $bg_color = imagecolorallocate($img, 255, 255, 255);     
  // white  
  $text_color = imagecolorallocate($img, 0, 0, 0);
  // black  
  $graphic_color = imagecolorallocate($img, 64, 64, 64);   
  // dark gray

  // Fill the background
  imagefilledrectangle($img, 0, 0, CAPTCHA_WIDTH, CAPTCHA_HEIGHT, $bg_color);
  // Draw some random lines
  for ($i = 0; $i < 5; $i++) {
    imageline($img, 0, rand() % CAPTCHA_HEIGHT, CAPTCHA_WIDTH, rand() % CAPTCHA_HEIGHT, $graphic_color);
  }

  // Sprinkle in some random dots
  for ($i = 0; $i < 50; $i++) {
    imagesetpixel($img, rand() % CAPTCHA_WIDTH, rand() % CAPTCHA_HEIGHT, $graphic_color);
  }

  // Draw the pass-phrase string
  imagettftext($img, 18, 0, 5, CAPTCHA_HEIGHT - 5, $text_color, './DejaVuSans-Bold.ttf', $pass_phrase);

  // Output the image as a PNG using a header  
  header("Content-type: image/png");  imagepng($img);

  // Clean up
  imagedestroy($img);
?>

Just started out with learning AJAX and the only way I know to pause a script to allow further input on the html form is by doing it with php, if you know how to do it with AJAX I'd be happy to alter it.

Skewled · August 14, 2010

So far still stuck on this issue, I appreciate those who are trying to help thus far.

Skewled · August 15, 2010

Let's see if today brings some luck.

PFMaBiSmAd · August 15, 2010

I don't see anywhere in this thread where you actually state what does happen when you submit the form? What do you see in front of you?

You should be using both of the following settings so that all the php detected errors will be both reported and displayed (actually your development system should have these two settings in your master php.ini so you don't need to put them into your code or remember to remove them later) -

ini_set("display_errors", "1");
error_reporting(E_ALL);

I also don't see any actual AJAX code involved and you should get your application working first before you attempt to use AJAX with it.

PFMaBiSmAd · August 15, 2010

if (isset($_POST['submit'])) {

^^^ Also, there's nothing in the posted code that sets $_POST['submit'] so your form processing code is being skipped over.

Did you do any basic debugging of this on your system while you were creating it and before you posted it here?

Skewled · August 15, 2010

I did I had error reporting on, I've been writing the script from the ground up as I learn more. It's just gotten so large that I overlooked things and needed help so I came here. So the error reporting wouldn't post anything for that type of mistake. I'll give that a whirl.

Skewled · August 15, 2010

Thank you for your assistance I appreciate it.

Edit: I noticed your edit and I had my signup form working prior to adding AJAX then tested after adding that and it worked, I added the human verification to it and that's when it screwed up.

When I submit the form nothing occurs and the account isn't registered. Also with the adjustments and corrections made to the submit function, and the value missing the " in the form I corrected that.

Can you look at the preg_match section and let me know If I did it correctly please?

Thanks,

Bill

Skewled · August 15, 2010

I've fixed the issues and now I'm certain it's down to the e-mail preg_match, my form is throwing back the error:

The email you have entered is invalid, please try again.

Edit: So what did I do wrong with my preg_match?

wildteen88 · August 15, 2010

I find the regulare-expressions.info site quite useful for commonly used regex patterns, such as matching email addresses

http://www.regular-expressions.info/email.html

Skewled · August 15, 2010

Thanks I'll check that out and that should fix the issue.

radar · August 18, 2010

By looking at your code you've got an odd way that you're doing your error checking... might i suggest doing your error checking all at once like:

if($_SESSION['pass_phrase'] != $phrase) { $e[] = "Pass Phrase doesn't match"; }

then when you get all your error checking done like so, to check if there are any errors you simply:

if(sizeof($e == 0) {

// everything is good

} else {

// there is at least 1 error

}

this makes it easier to debug, and makes it easier to read.

A sample of this would be like this, i have the sneaking suspicion i am missing a } somewhere in the code probably right @ the very end..... You may also want to look and make sure I have all the error checking done... but doing something like this instead of how you had it would theoretically work a bit better than how you had it coded.

<?php

$passname = mysqli_real_escape_string($dbc, trim($_REQUEST['username']));
   // Lookup the username in the database
    $query = "SELECT username FROM info WHERE username = '$passname'";
    $data = mysqli_query($dbc, $query);
   // Allow some time to get the response

   // If 1 is returned that name exsists, if 0 then we can move forward
	if (mysqli_num_rows($data) == 0) {
