hi all basically i'm making a php and sql registration form?

and i'm getting this error $p2 = $_POST['p2'];

my code is this

PHP:

<?php
$error = NULL;

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

    //Get form data
    
    $u = $_POST['u'];
    $p = $_POST['p'];
    $p2 = $_POST['p2'];
    $e = $_POST['e'];
    
    
    
    
    if(strlen($u) < 5){
        $error = "<p>Your username must be at least 5 characters</p>";
    }elseif($p2 != $p){
        $error .= "<p>Your passwords do not match</p>";   
    }else{
        //Form is valid
        
        //Connect to the database
        $mysqli = NEW MYSQLi('localhost','root','','profiles');
        
        //Sanitize form data
        $u = $mysqli->real_escape_string($u);
        $p = $mysqli->real_escape_string($p);
        $p2 = $mysqli->real_escape_string($p2);
        $e = $mysqli->real_escape_string($e);

        //Generate Vkey
        $vkey = md5(time().$u);
        
        //insert account into the database
        $p = md5($p);
        $insert = $mysqli->query("INSERT INTO accounts(usname,password,email,vkey)
        VALUES('$u','$p','$e','$vkey')");
        
        if($insert){
            echo "Success";
        }else{
            
        }
        
        
    }
}   
        

?>
<html>
<head>
<link href="style.css" rel="stylesheet" type="text/css" />
</head>

<body>
<form method="POST" action="">
  <table border="0" align="center" cellpadding="5">

That is not an error code, it's the third line of collecting data from your form. Your PHP code has a problem with that statement.
You should do a test and print the '$p' and '$p2'. If you still get an error research the correct one and not $p2 = $_POST['p2'];

Your REPEATED password is named 'r' not 'p2'.

If your running this as a single file that's what happens, because the first time through you haven't defined those. Set the PHP as a separate file and call it from the HTML form.

strawbs you allways need to be mindful that PHP run at the server and HTML runs in the browser. This file will not run as you want. This line:
<title><?php echo $firstname; ?> <?php echo $lastname; ?>s Profile</title>
Needs to know $firstname and $lastname which is not known until line 17 and 18:

Code:

while($row = mysqli_fetch_array($userquery, MYSQLI_ASSOC)){
    $firstname = $row['firstname'];
    $lastname = $row['lastname'];

Your error is caused by a missing ; at the end of line 36.
You'll get more errors in the table because of this:
<? php echo $firstname: ?>
in all rows. Notice the space after the ?. Should be <?php

FYI -> Back in ver 5.4 of PHP a short hand way of writing <?php echo was introduced <?= Easier right?

Have you never been taught to troubleshoot strawbs?

If you read my last post you made a new program, you did re-program right, because I told you you fetch data in the wrong place. So post both the calling form and new form you just re-wrote.
