POST[submit] Problem?

I'm having a problem with using POST[submit]. I have a page that has a side bar with a box that runs a search. I also have a page where a user can log in. The problem is when I try to log in (login.php), the search.php runs when I click the log in button. How can I fix this? Is there a way to name seperate _POST to check which button was clicked (or which text box was submitted by pressing enter)?
Code for Login.php

<?php # login.php
// This is the login page for the site.

// Include the configuration file for error management and such.
require_once ('includes/config.inc'); 

// Set the page title and include the HTML header.
$page_title = 'Login';
include ('includes/header.html');

if (isset($_POST['submit'])) { // Check if the form has been submitted.

	require_once ('mysqli_connect.php'); // Connect to the database.
	
	if (empty($_POST['username'])) { // Validate the username.
		$u = FALSE;
		echo '<p><font color="red" size="+1">You forgot to enter your username!</font></p>';
	} else {
		$u = escape_data($_POST['username']);
	}
	
	if (empty($_POST['password'])) { // Validate the password.
		$p = FALSE;
		echo '<p><font color="red" size="+1">You forgot to enter your password!</font></p>';
	} else {
		$p = escape_data($_POST['password']);
	}
	
	if ($u && $p) { // If everything's OK.
	
		// Query the database.
		$query = "SELECT id, username FROM users WHERE username='$u' AND password=PASSWORD('$p')";	

		$result = mysqli_query ($dbc, $query);
		$row = mysqli_fetch_array ($result); 
		
		if ($row) { // A match was made.
				
				// Start the session, register the values & redirect.
				$_SESSION['username'] = $row[1];
				$_SESSION['id'] = $row[0];
				
				ob_end_clean(); // Delete the buffer.
				
				header ("Location:  http://" . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . "/index.php");
				exit();
				
		} else { // No match was made.
			echo '<p><font color="red" size="+1">The username and password entered do not match those on file.</font></p>'; 
		}
		
		mysqli_close($dbc); // Close the database connection.
		
	} else { // If everything wasn't OK.
		echo '<p><font color="red" size="+1">Please try again.</font></p>';		
	}
	
} // End of SUBMIT conditional.

If your search.php logic is being called, that means there's some kind of error in your HTML.. Mainly your form action. I would recommend hard coding it, instead of PHP_SELF.

On another note, this post sure would have been nicer to read if you wrapped your code in the proper code tags.

Hmm I'm not sure what you mean by hard coding instead of using self?
I though I did wrap it in the [*code*] tags? I clicked the little code button and pasted it in there...

Keep in mind that you have to change the action attribute for each of your forms. I noticed that your email form where you have the newsletter signup is still using action="search.php" which I don't think is what you want to be doing.

Yes I have not done anything with the newsletter portion yet.

Actually I just changed it to newsletter.php (without making the page) and it is trying to go there (obviously saying the page is not found).

The code is in code tags? Nicely separated into the separate files too?

Yes each seperate code section is a different file. Login logs the user in. Header.html displays the header and side bar. Search.php searches for a string that is entered in the text box of the side bar (which is in the header.html).
