Ok soon i can't take this any more, there IS nothing wrong with this code! I've checked it, i have double checked it, tripple checked and then checked it again bit for bit and I can't find anything that suggest i should get these messages:

 

Notice: Undefined index: birth_month in 

 on line 30


Notice: Undefined index: birth_day in [php file location] on line 31


Notice: Undefined index: birth_year in [php file location] on line 32


Notice: Undefined index: iagree in [php file location] on line 33[/b]


[size=14pt]I have one file with the HTML form named "register.php" and another file with the PHP code to process the form named "class.register.php". I don't know if it matters but i have to solve this to be able to move on with my website so i'll try to bring you all the facts and info i have..[/size]


[size=14pt]Here is the HTML file/code (register.php):[/size]

[code]<?php

session_start();


if(isset($_POST['register']))

{

  include_once('classes/class.register.php');


  $register = new Register();


  if($register->process())

    echo "Successfully Signed Up!";

  else

    $register->show_errors();

}


$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));

?>

I really need help with this.. So if you have 10 min or so to scroll through my code and see if you can see any direct faults i would really appreciate it! Cause I can't find anything wrong with it!

 

[size=14pt][i]Note: I tried to solve it by changing the top part of the PHP code from:[/i][/size]

[code=php:0]$this->birth_month  = $this->filter($_POST['birth_month']);
$this->birth_day    = $this->filter($_POST['birth_day']);
$this->birth_year  = $this->filter($_POST['birth_year']);
$this->iagree      = $this->filter($_POST['iagree']);[/code]

 

[size=14pt][i]To:[/i][/size]

[code=php:0]$this->birth_month  = $this->filter($_POST['birth_month'] = "");
$this->birth_day    = $this->filter($_POST['birth_day'] = "");
$this->birth_year  = $this->filter($_POST['birth_year'] = "");
$this->iagree      = $this->filter($_POST['iagree'] = "");[/code]

 

[size=14pt][i]That did take away the messages but instead whenever i for example chose a date in the dropdown menu it would always return false..[/i][/size]

Ok I tried to change the code from:

<?php
session_start();

if(isset($_POST['register']))
{
  include_once('classes/class.register.php');

  $register = new Register();

  if($register->process())
    echo "Successfully Signed Up!";
  else
    $register->show_errors();
}

$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));
?>

 

To:

 

<?php
session_start();

if(isset($_POST['token']))
{
  include_once('classes/class.register.php');

  print_r($_POST)

  $register = new Register();

  if($register->process())
    echo "Successfully Signed Up!";
  else
    $register->show_errors();
}

$token = $_SESSION['token'] = md5(uniqid(mt_rand(),true));
?>

 

But then i just get this error message, i don't know how to fix that:

Parse error: syntax error, unexpected T_VARIABLE in 

 on line 10[/b]

Whenever you get an error, look at the line it's referencing, and the ones before and after it. Check for common problems like typos.

I'm sorry my bad, didn't look hard enough!

 

Well then i get this at the top of my webpage, what does it mean really?

 

Array ( [username] => [first_name] => [last_name] => [password] => => [confemail] => [gender] => Man [register] => Sign Up [token] => 69317acbf5cf9a58fa61490250f9e06c )

 

do you get those errors on post? using your code, i only get one notice when iagree isn't checked:

 

Notice: Undefined index: iagree in 

 on line 33

 

What editor are you using to update your files?

 

I get the "Notice" errors when i hit the sign up button. I use Notepad++!

it shows that all of those POST variables are empty except for gender, register and token. pretty weird, as your code seems to work fine here.

I use the latest version of Chrome.

 

All of the fields are empty because i didn't type anything in them, I've forgotten to mention that if i choose something in the date field or klick "I Agree bla bla.." i can sign up successfully as you say you can if you try. But it's only when i don't choose anything that the errors appear. How could i forget to write that..

I want to fix it cause i don't want any error messages to show up if a person signs up at my website and types something wrong or forget to check a checkbox!

yes, exactly. i already typed this, so here is an example:  ;)

 

if (isset($_POST['username'])) {
     $this->username     = $this->filter($_POST['username']);
} else {
     $this->username = '';
}

 

DOH, and already posted once above by Jesirose. i wish I paid more attention to what's already been posted.

That's the purpose of field validation, which you should also be doing. Error reporting should not be enabled on a live production site.

Ok thanks everyone for the help, i really appreciate it!

 

I used what jesirose and BlueSkyIS said and it helpt me to understand a little more about the problem but still that wasn't the solution. Infact I have no idea what solved it? Cause I spent the whole yesterday evening trying to solve it and finally i gave up too try agin in the morning.. And now when i click on "Sign Up" in my registration form, i don't get any error messages anymore so I can't say what the problem was.

 

Anyway, the problem is gone! Thanks again all!

 

Also:

I know this, but how do turn error reporting off?
