Answer 1

<?php
include("config.php");
$cart=$_POST['cart'];
$numberofcart=$_POST['numberofcart'];
$values ='';

if ($cart !=='' && $numberofcart !=='') {
    for($i=0;$i<$numberofcart;$i++){
        $values .= "('$cart','150LE'),";
    }
    $values = trim($values,',');
    mysql_query("INSERT INTO trade (cart,price) values $values");// good to change connection code in file according to mysqli_* standards
}else{
    echo "form field are required";
}
?>


<form action="index.php" method="POST">
  <input type="text" name="cart" />
  <input type="text" name="numberofcart" />
  <input type="submit" />
</form>
