Hello!

I need help how to solve this error. Anyone is welcomed. I am a newbie in this php thing.
The error occurs in this line:

PHP

<?php echo $validate_msg; echo $checkuser; echo "<br/>"; echo $msg; ?>

Here are the codes with errors.

PHP

	// Validate e-mail address
	if(filter_var($submitemail, FILTER_VALIDATE_EMAIL))
	{
		if($numrows == 0)
		{
			$stmt->execute();
			$stmt->close();
		}
		else
		{
			$checkuser = "Username Or Email Already Used";
		}
	} 
	else
	{
		$validate_msg = "$submitemail is Not valid email address";
	} 

        if($conn->insert_id)
        {
            $msg = "<h3>Registered successfully.</h3>";
        }
        else
        {
			$msg = "Registration Failed";
		}
       
    }
		
?>

<body>

<div style="margin-top:5%" class="container">
  
    <div class="col-sm-4">
    </div>
    
  <div class="row">
    
    <div class="col-sm-4" style="background:#eeeeee;">
		<?php echo $validate_msg; echo $checkuser; echo "<br/>"; echo $msg; ?>

Try Initialize variables to empty and see. Scope wise global.

<?php
// Initialize variables to empty.

$checkuser = '';
$validate_msg = '';

Thanks a lot. It really helps..

Unfortunately, another error displayed. It says "Registration Failed" but when I checked on the phpmyadmin, the input details are reflected but the
Hide Copy Code
$id
returns 0. Maybe its the reason why it prompted "Registration Failed". Any help please.

Sorry, but without the actual code we have no way of guessing what is happening.
