    Do you mean by "change behaviors at run time" that I shouldn't call my objects (like message, encryption, formValidator etc.) in the user class, instead call them on the registration script? So that all the objects doesn't form as one system in the user class, but as one system at run time.
  2. php-beginner
    Okay, Could you be more specific of what I don't understand. What I know is that objects should be re-usable, thats what I'm doing. And if ever needed in other projects, I could simply use the classes that are already made and leave the classes I don't need. Thanks for your suggestions, I'll take a look at those books.
  3. php-beginner
    Great, Thankyou very much for all your help. I have only one question left: Is the way I make use of object orientated programming good? Or did I wrong interpreted the way objects should be handled? You would probably do it differently, but everyone has his own way I think. Anyway, I'm new to OOP and I hope I understand it quite well now.

    This does also work but am not sure if this is allowed: I change the message class in my user class to public; I change the function where I "echo" to "return $this->errorMessages;" Now I add this in my registration script to check if the object has been set ... : <?php if(isset($user)){ if($user->message->messageStatus != false){ echo 'Oops...'; echo '<ul>'; foreach($user->error as $msg){ echo '<li>'. $msg .'</li>'; } echo '</ul>'; } } ?> This means that I can remove this code from my user class because this is already set on the registration script: <?php if($this->message->messageStatus != false){ // etc; } ?> This way I don't have to rewrite lots of code.
  5. php-beginner
    I don't understand how I could implement this in my code. However, I see that you use $error. But the errors are stored in an array so I can't echo it like that.
  6. php-beginner
    Ah ok, I will try to figure that out , Thankyou so far!
  7. php-beginner
    So this means I have to cut the output from the processing and parse it within my presentation (html)? Or just set the doctype at top which also solves this problem?
  8. php-beginner
    Correct me if I'm wrong but, if the error messages should be at the beginning of the page like the rest of the php code then the error message will be above the doctype. So the error message script should be set in the html part?

    Allright. Well, like I said, I already have a form validator, mysql_real_escape_string, etc. This is all done by different classes. My problem is now that my message class outputs this error but this is not done within the doctype. So I have a bunch of classes inside the user class that handle this registration. The user class checks with other classes if the input is correct etc and if user already exist etc and if not a message is echo'ed by my message class. Now I know that echoing inside a class/object is not the best method, that turns out now So what is the best way to get the errors outputted inside the doctype? Do I have to return the message and echo it somewhere else? If so, where? So far, thankyou for your help.
  11. php-beginner
    Also the doctype should still be above the php because when I submit the form, this is what happens: Oops...<ul><li>Uw voornaam voldoet niet aan de eisen.</li><li>Uw achternaam voldoet niet aan de eisen.</li><li>Uw adres voldoet niet aan de eisen.</li><li>Uw postcode voldoet niet aan de eisen.</li><li>De plaatsnaam voldoet niet aan de eisen.</li><li>De gebruikersnaam voldoet niet aan de eisen.</li><li>Het wachtwoord voldoet niet aan de eisen.</li><li>Ongeldig e-mailadres.</li></ul> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head> <title>registration</title> <link rel="stylesheet" type="text/css" href="opmaak.css" /> </head> //etc The <ul> isn't presented under the doctype. Or did I misunderstood something?
  12. php-beginner
    I thaught that this was better? if ($_SERVER['REQUEST_METHOD'] == 'POST'){ People told me that this is more secure. Also a dutch website confirms this: http://www.pfz.nl/wiki/isset-vs-request-method/
  13. php-beginner
    @JKG Lol. I feel like a fool now Thankyou! @Nightslyr Thankyou for your explanation. I will update my code and never forget that because I had that error once. But the whole input validation is already done. The user object and the objects within the user object take care of this.
  14. php-beginner
    @JKG No it was not a fix, I am very sorry xD This is because I check if the form has been submitted. If so, then show errors with the user input in form. If not, then show the normal form. This means that with this fix, the user can only see the form if it has been submitted. So users that didn't filled in the form, they can't fill it in because they cannot see it. So this is still the best way i think: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head xmlns='http://www.w3.org/1999/xhtml'> <title>registration</title> <link rel="stylesheet" type="text/css" href="opmaak.css" /> </head> <body> <?php function __autoload($class){ require('classes/' . strtolower($class) .

    Great fix, thankyou (no it was not, see next comment(s))
  16. php-beginner
    Ah ok. Yes I saw that. But this is more user friendly then your way. Also, it doesn't always remember the input in some cases (that's what I've been told). But if I want it my way, I have to do it this way (right?): <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head xmlns='http://www.w3.org/1999/xhtml'> <title>registration</title> <link rel="stylesheet" type="text/css" href="opmaak.css" /> </head> <body> <?php function __autoload($class){ require('classes/' . strtolower($class) .

    Thankyou for your reply. Also sorry for my last post. I forgot the echo xD, so it does work. If a user types in wrong characters, they get a message from my message object etc. But, when I do that the user input is gone. I don't want that. I want to hold the user input so that they don't have to rewrite everything and see what they have done wrong. In your example, the user input is not remembered. So I am forced to write my html code twice. Correct me if I'm wrong.
  18. php-beginner
    Do you mean something like this? This won't work. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head xmlns='http://www.w3.org/1999/xhtml'> <title>registration</title> <link rel="stylesheet" type="text/css" href="opmaak.css" /> </head> <body> <?php function __autoload($class){ require('classes/' . strtolower($class) .

    Hello everyone, I want my input to stay after I have clicked submit so that if the input is wrong, a message is presented and the input stays so they don't have to write everything again. Is this the way to do it?: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html> <head xmlns='http://www.w3.org/1999/xhtml'> <title>registration</title> <link rel="stylesheet" type="text/css" href="opmaak.css" /> </head> <body> <?php function __autoload($class){ require('classes/' . strtolower($class) .

    Ok, thankyou for your explanation. Then I will only check if they already have registrated with the same IP. And if they still want to make multiple accounts by using a proxy, then so be it.
  21. php-beginner
    Isn't there anyone that has dealed with this before? I'd like to know which method is best for this problem. Any good tutorials?
  22. php-beginner
    I don't want users to registrate themself twice on the same address.
  23. php-beginner
    Thankyou for your reply. But what can I do to prevent this as much as possible? Or do I only use $_SERVER['REMOTE_ADDR']?

    Hello guys, I have been searching on the internet for articles that shows me how to get the real IP address when they are behind a proxy. But after some reading it seems that this is not completely possible. Correct me if I'm wrong. So what is the best thing to do? Because I have seen different methodes and I'm not sure which one is the best. http://www.laughing-buddha.net/php/lib/remoteip
  25. php-beginner
    About the error handling. I could use exceptions for that right? I can't think of a situation when this could go wrong.
