PHP-General - New website, looking for registration code

Hello. I am new to PHP and I want to add something to a website that I will be opening. Basically, I want to be able to have a code that does not allow a user to have the same password as their username. Can anyone help me?

Thank you guys,

Send a message via Google Talk to requinix

Then find the places where users register and where they change their passwords, and in the validation parts add a check that their username isn't the same as the password.

thank you for the link. What I meant is the code that I add on registration page that prevent my customers to have a matching username and password.

Cheers

The easiest way to do this would be with JavaScript.

You can check out this page by W3C to find out more about form validation.
http://www.w3schools.com/js/js_form_validation.asp

Here's an example tailored to your need:

Code:

<html>
    <head>
        <title>
            Example Page
        </title>
        <script type="text/javascript">
            function validateForm() {
               if (document.forms["myForm"]["username"].value == document.forms["myForm"]["password"].value) {
                   // Display notification
                   document.getElementById('notification').innerHTML = 'Your username and password must be different.';
                   // You must return false to avoide actual form submission
                   return false;
               }
            }
        </script>
    </head>
    <body>
        <span id="notification" style="color: red;"></span>
        <form method="post" action="myfile.php" name="myForm" onsubmit="return validateForm()" >
            <input type="text" name="username" id="username">
            <input type="text" name="password" id="password">
            <input type="submit" name="submit" id="submit">
        </form>
    </body>
</html>

Keep in mind...
You must also perform this check in your PHP POST script if you want to enforce it. If you *only* perform the check with JavaScript, the user could just disable JavaScript to bypass it. JavaScript is just a nice way to give the user some instant feedback.

What you're asking for isn't difficult to do; it just involves adding a simple if statement. It's really impossible to go into any more specific details without knowing exactly what your code looks like.

hi

Please find the answer.

PHP Code:


		
			
<?php

$userName=mysql_real_escape_string($_POST['user_name']);

$userPass=mysql_real_escape_string($_POST['user_password']);

$errors=array();

if($userName === $userPass){

$errors[]="Your UserName and Password must be different";

}

if(empty($errors)){

 $query="insert query here...";

 $result=mysql_query($query);

}else{

 foreach($errors as $error){

  echo $error.'<br>';

 }

}

mysql_close();   

?>
