PHP - Getting Url Parameter .. Not As Easy As It Seems

I have the following code just to insert a username and hashed password into the database but somehow I am getting this error and I couldn't find out where I am doing it wrong...can someone please give me a hand?   I tried it in two ways and both errors... the first few lines are just connecting database which worked fine and a password.php so I can use password_hash() with my php version

$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));
$username = 'xx';


$insertQuery = $db->prepare("
		INSERT INTO et_todo (username, password)
		VALUES (:username, :hash)
	");

$insertQuery->execute(array(
		'username' => $username,
		'password' => $hash
	));

also tried

$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));

$insertQuery = $db->prepare("
		INSERT INTO et_todo (username, password)
		VALUES ('xx', :hash)
	");

$insertQuery->execute(array(
		'username' => 'xx',
		'password' => $hash
	));

Hello,   I recently posted here about an issue I was having with my database orientated products page.   I have now run into another problem where say if, /db.php was typed or /db.php?p=IDoNotExist was typed, it returns blank.   I have in my code the desired content to be displayed, but it just doesn't seem to want to make a show.   I was also wondering if it is possible to show different content for whatever the URL is, so for no parameter, the content about the products, and a non existent one, maybe "Product not found"?   Here is my code:

<?php
	$db=mysql_connect  ("localhost", "webwibco_charlie",  "Hello123") or die ('I cannot connect to the database  because: ' . mysql_error()); 
	$mydb=mysql_select_db("webwibco_products"); 

	include("header.php");

	$status = htmlspecialchars( @$_GET ['p'] );

	if ($status == "floorpuzzles") {

		     echo "<h1>Our Floor Puzzles</h1>";
		$sql="SELECT  ID, Name, Tags, Description, Category FROM products WHERE Category LIKE '%" . FloorPuzzles .  "%'"; 
		$result=mysql_query($sql); 
		while($row=mysql_fetch_array($result)){ 
			$Name  =$row['Name'];
			$ID  =$row['ID']; 
			$Description  =$row['Description'];  
			echo "<div class=\"box\">";
			echo "<h1>$Name</h1>";
			echo "<div class=\"floorbox\"><a href=\"?p=$ID\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"small\"></a></div>";
			echo "<h2>$Description</h2>";
			echo "</div>";
		}
?>
<?
}else{



	if ($status == $_GET["p"]) {
		$sql="SELECT  ID, Name, Tags, Description, Pieces, Size, Barcode, Category FROM products WHERE ID = '" . $_GET['p'] .  "'";   
		$result=mysql_query($sql);   
		while($row=mysql_fetch_array($result)){  
			$Name  =$row['Name'];
			$ID  =$row['ID']; 
			$Description  =$row['Description']; 
			$Pieces  =$row['Pieces']; 
			$Size  =$row['Size']; 
			$Barcode  =$row['Barcode'];   
			echo "<div class=\"1\">";
			echo "<h1>$Name</h1>";
			echo "<div class=\"bigbox\">";
			echo "<div class=\"floorbox\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"big\"></div>";
			echo "</div>";
			echo "</div>";
			echo "<div class=\"2\">";
			echo "<p>Puzzle Pieces: $Pieces</p>
				  <p>Puzzle Size: $Size</p>
				  <p>Barcode: $Barcode</p>";
			echo "</div>"; 
		} 
		}else{
?>
<?
			echo"<h1>Our Products</h1>
				<p>Our jigsaw puzzles are hand cut by skilled craftsmen and therefore each one is unique with self-correcting pieces. There is a strict quality control process at all stages by our highly experienced staff. The puzzles are durable and provide fun and excitement, enhancing learning and a child’s development.<p>
				<p>All of our jigsaws are made using materials from sustainable resources grown in managed forests. Where possible we support companies in the UK and source our components locally, most of our suppliers are in the East Midlands, many in Derbyshire and Nottinghamshire. We keep packaging to a minimum and take our environmental and ethical responsibilities very seriously.</p>
				<p>Reducing waste and recycling was a way of life for us before it became fashionable. We are constantly searching for new ideas and consult teachers when developing our jigsaws, which are often used within the national curriculum.</p> 
				<p>As well as making our own range, we manufacture for leading suppliers to the education market. Check for \"Made in Britain\" and it is probably made by us.</p>
				<p>We have a wide variety of products available for viewing, from classic floor puzzles to innovative inset trays. You can take a look at all our products on this page, simply use the navigation buttons to your left.</p>";

				
				}}

include("footer.php");
?>

The final echo is what I wish to be displayed on the URL without or with an invalid parameter.   Here is my site URL: http://www.webwib.co...saws/search.php (note that only the "Floor Puzzles" category has content within it).   Thank you in advance for assistance.

    }How to remove feature=player_embedded& from $url ?

Hi guys, please help me to solve my problem. i want to get the url parameter using / for now i use index.php?category_id=14 how can i change the ?category_id=14 to index.php/14   thank you so much.

I have a pagination class that uses PHP_SELF to display the proper URLs when generating the pagination buttons.  I need PHP_SELF to be a class parameter so that if the page is not defined in the parameter, then use PHP_SELF.  The reason for this is because I generate the class in an ajax file and it is returning the URL of the ajax file, not of the page I am running the ajax on. I just don't know how to add the parameter to the class.

The class is below:

Code: [Select]
