Validating Data with a conditional

[jryan54]

Hey guys,

Pretty brand new to PHP so learning as I go.

I've got a web form which posts to a file called signup.php. Now within this file i'm trying to take a post variable $_POST[name] and see if its actually empty.

I have an if loop in place to check BUT no matter what I do it doesnt seem to fire. It def has something to do with the code below it because it works when I remove that code.

Anyway, any ideas?

P.S I know its horrible code but im slowly learning bit by bit.

if ( ! empty($_POST['name']))
 	{  
        
    }
	else
	{
	 header('Location:signup.php');
     }
	 
	 

// escape user input

$_POST[name] = mysql_real_escape_string($_POST[name]);
$_POST[email] = mysql_real_escape_string($_POST[email]);
$_POST[company] = mysql_real_escape_string($_POST[company]);
$_POST[country] = mysql_real_escape_string($_POST[country]);
$_POST[password] = mysql_real_escape_string($_POST[password]);

// Encrypt the password using MD5

$_POST[password] = md5($_POST[password]);

// store client ip address to variable
$ip = $_SERVER['REMOTE_ADDR'];   

// Insert sanitized POST data into the mysql database

$sql="INSERT INTO sellers (name, email, company_name, country, password, ip_address)
VALUES
('$_POST[name]','$_POST[email]','$_POST[company]','$_POST[country]','$_POST[password]','$_POST[ip]')";

if (!mysql_query($sql))
{
die('Error: ' . mysql_error());
}


header('Location:signupsuccess.php');

At a minimum, you're missing all the quotes in the post array references...

$_POST['name'] = mysql_real_escape_string($_POST['name']);

Thanks for that...okay i've added in the quotes....obviously still no effect upon my IF statement.

So clearly something still going on.

Anyone? bueller bueller?

PHP Code:

if (empty($_POST['name'])) {header('Location:signup.php');} 


Based on what you had in the original post it looks like you want to go to the signup page if the name field on the form is blank.
