Answer 1

<?php 
 // Connects to your Database 
 mysql_connect("hostname", "username", "password") or die(mysql_error()); 
 mysql_select_db("Database_Name") or die(mysql_error()); 
 $data = mysql_query("SELECT * FROM cars where cars.carType = 'chevy' AND cars.active = 1") 
 or die(mysql_error()); 
 Print "<table border cellpadding=3>"; 
 while($row= mysql_fetch_array( $data )) 
 { 
 Print "<tr>"; 
 Print "<th>Name:</th> <td>".$row['name'] . "</td> "; 
 Print "<th>ImagePath:</th> <td>".$row['imagePath'] . " </td></tr>"; 
 Print "<th>Description:</th> <td>".$row['description'] . "</td> "; 
 Print "<th>Price:</th> <td>".$row['Price'] . " </td></tr>"; 
 } 
 Print "</table>"; 
 ?> 

Answer 2

you are not querying to database so it wont give you result

this is how it works

1) connect to the database by mysql_connect()

mysql_connect("localhost", "username", "password") or die(mysql_error()); 

2) than select the database like mysql_select_db()

mysql_select_db("Database_Name") or die(mysql_error()); 

3) you need to use mysql_query()

like

 $query = "SELECT * FROM cars where carType = 'chevy' AND active = 1";
 $result =mysql_query($query); //you can also use here or die(mysql_error()); 

to see if error

4) and than mysql_fetch_array()

  if($result){
         while($row= mysql_fetch_array( $result )) {
             //result
        }
      }

so try

$data = mysql_query("SELECT * FROM cars where carType = 'chevy' AND active = 1")  or die(mysql_error()); 
 echo"<table border cellpadding=3>"; 
 while($row= mysql_fetch_array( $data )) 
 { 
    echo"<tr>"; 
    echo"<th>Name:</th> <td>".$row['name'] . "</td> "; 
    echo"<th>ImagePath:</th> <td>".$row['imagePath'] . " </td></tr>"; 
    echo"<th>Description:</th> <td>".$row['description'] . "</td> "; 
    echo"<th>Price:</th> <td>".$row['Price'] . " </td></tr>"; 
 } 
 echo"</table>"; 
 ?> 

Note:

Mysql_* function are deprecated so use PDO or MySQLi instead . I would suggest PDO its lot more easier and simple to read you can learn here PDO Tutorial for MySQL Developers also check Pdo for beginners ( why ? and how ?)
