Code:

<form action='register.php' methot='POST'>

change to:

Code:

<form action='register.php' method='POST'>

methot -> method...

I still get the dam message:

<?php
echo "register<br>";
$submit = $_POST['submit'];
$navn = strip_tags($_POST['navn']);
$username = strip_tags($_POST['username']);
$password = strip_tags($_POST['password']);
$repeatpassword = strip_tags($_POST['repeatpassword']);

$data = date("Y-m-d");
if ($submit)
{
if ($navn&&$username&&$password&&$repeatpassword)
{
$password = md5($password);
$repeatpassword = md5($repeatpassword);

if ($password==$repeatpassword)
{
if (strlen($username)>25||strlen($navn)>25)
{
echo "Dit brugernavn eller navn er for langt.";
}
else
{
if (strlen($password)>25||strlen($password)<6)
{
echo "Dit password må kun være mellem 6 og 25 bogstaver eller tal.";
}
else

}

}

}
else
echo "Dine password passer ikke sammen.";

Code:

<?php
if (isset($_POST['submit']))
{

// Put your entire PHP code here

}
?>

If you do not know even a simple thing like a post then you shouldn't be coding.

Example of form that I use:

PHP:

<? if (isset($_POST['Submit'])) {
					
					$username	= mysql_real_escape_string($_POST['username']);
					$password	= mysql_real_escape_string($_POST['password']);
					$password2	= mysql_real_escape_string($_POST['password2']);
					$email		= mysql_real_escape_string($_POST['email']);
					$ip			= $_SERVER['REMOTE_ADDR'];
					
					$query = "SELECT * FROM accounts WHERE username='".strtolower($username)."';";
					$query2 = "SELECT * FROM accounts WHERE lastip='".$ip."';";
					$res = mysql_query($query);
					$res2 = mysql_query($query2);
					
					if(empty($username) || $username == "")
					{
						echo "Username field is empty";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(empty($password) || $password == "")
					{
						echo "Password field is empty";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(empty($password2) || $password2 == "")
					{
						echo "Password confirmation field is empty";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(empty($email) || $email == "")
					{
						echo "EMail field is empty";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(strlen($username) > 10)
					{
						echo "Username can't be longer than 10 characters";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(strlen($username) < 4)
					{
						echo "Username can't be smaller than 4 characters";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(strlen($password) > 10)
					{
						echo "Password can't be longer than 10 characters";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(strlen($password) < 4)
					{
						echo "Password can't be smaller than 4 characters";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(strlen($email) > 60)
					{
						echo "Email can't be longer than 60 characters";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(!isAlphaNumeric($username))
					{
						echo "Username can be alphanumeric only. It means it can have letters and numbers in it only.";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif($password != $password2)
					{
						echo "Passwords do not match";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(mysql_num_rows($res) > 0)
					{
						echo "Sorry such account already exist.";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					elseif(mysql_num_rows($res2) > 2)
					{
						echo "Sorry you can have only 3 accounts per IP.";
						echo "<br /><a onclick='history.back();' href='#'>Go back</a>";
					}
					else
					{
						$insertUser = mysql_query("INSERT INTO `accounts`(username,password,email) VALUES ('".strtolower($username)."', '".md5($password)."', '$email');");
						
						if($insertUser)
						{
							echo "Account has been created. Enjoy :)";
							echo "<br /><br />";
							echo "<h2>Account information</h2>";
							echo "Username: " . strtolower($username) . " (all lower case) <br />";
							echo "Password: " . $password . " (case sensative) <br />";
							echo "Email: " . $email . " (used to restore/change password) <br />";
						}
						else
						{
							echo "Strange error occured. Please contact administrator";
						}
					}
				} else {
				?>
				
				<p>
					<form action="index.php?id=registration" method="post">
						<table border="0" width="100%">
							<tr>
								<td>Username:</td>
								<td><input type="text" name="username"></td>
							</tr>
							<tr>
								<td>Password:</td>
								<td><input type="password" name="password"></td>
							</tr>
							<tr>
								<td>Password confirmation:</td>
								<td><input type="password" name="password2"></td>
							</tr>
							<tr>
								<td>Email:</td>
								<td><input type="text" name="email"></td>
							</tr>
							<tr>
								<td><input type="reset" name="Clear" value="Clear"></td>
								<td><input type="submit" name="Submit" value="Create account"></td>
							</tr>
						</table>
					</form>
				</p>
				
				<? } ?>

You can use following instead of "elseif"

PHP:

if (condition)
{
// Code here
}
else
{
    if (condition2)
    {
    // do another code here
    }
    else
    {
         if (condition3)
         { 
         // do another thing
         }
         else
         {
         // and so on
         }
    }
}

I pay for my bandwidth.

You post 50845690840689405860456804686 threads asking mundane questions about PHP that could be answered by spending 20 minutes reading the Ducking manual.

So I load the coder forum and as such am inundated with shenanigans created by you to do your work for you, which had you had even an IQ of 80 would've been able to figure out yourself.

As such, following from the first statement, you owe me money for wasting the bandwidth I pay for.

Thanks much, moron.

Does it honestly matter if you pay for bandwith? Doesn't give you extra rights to spam, flame, or break the rules. Although yes I do understand you and why your aggravated. Still doesn't give you extra rights so get over it?

And back on topic. Your setting vars before they're defined.

PHP:

<?PHP
if(isset($_POST['submit'])) {
$register = $_POST['register'];
//Continue vars here. And continue your script.
}
?>
//Then your form will go here with the method = "post".
//Could also do action = "<?PHP $_SERVER['PHP_SELF']; ?>";
//Your choice. Either way its going to give you the same results.

Although next time, read some tutorials through possibly w3 schools. Or even tizag, they have some great beginner references.

Means they have no valu so you might of put the wrong I'd in the forms

Most forums ban people who repeatedly ask stupid questions (questions solved by a quick google, or Ring TFM). Feel free to check the board rules as well. It's pretty clearly stated.

Also, people who fail to make grammatically correct posts while criticizing others typically are ridiculed.

Massive necro from pletcherntn. I reported it a while ago but the post is still there.. meh.

jMerliN · Sep 12, 2012

Maybe the mods have nercolepsy?

s-p-n · Sep 12, 2012

Maybe because everybody is replying and it stays at the top, and everyone knows how to use $_POST and comes here to get disappointed more than once...
