Inportant Problem with delete in PHP/pg_sql

[Steve4900]

I have a shopping basket and i want a user to select from a check box a game that they dont want to buy which they entered by mistake this is what i got so far

$conn = pg_connect("blah blah");

            echo '<form name="hede" method="POST" action="cart.php">';


            	echo "<table border='5'>";

		$res = pg_query ($conn, "SELECT * from Top where $res=e($sql);");
            while ($row = pg_fetch_assoc($res)) {
                echo "<tr>";
                    echo "<td>";
                    echo "<input type=\"checkbox\" name=\"games[]\" value=\"" . $row['refcode'] ."\">";
                    echo "</td>";
                    echo "<td>";
                    echo $row['title'];
                    echo "</td>";
                    echo "<td>";
                    echo $row['description'];
                    echo "</td>";
                    echo "<td>";
                    echo $row['price'];
                    echo "</td>";
                echo "</tr>";
		 if($delete){
for($i=0;$i<$count;$i++){
$del_id = $checkbox[$i];
$sql = "DELETE FROM Top WHERE id='$del_id'";
$res = e($sql);
        }
	}
	}
	echo "</table>\n";
        echo '</form>';
?>

 

But i think im getting my_sql confused with postgresql any ideas cheers
