PHP: prepared statement, IF statement help needed

Question

I have the following code:

$sql = \"SELECT name, address, city FROM tableA, tableB WHERE tableA.id = tableB.id\";

if (isset($price) ) {
    $sql = $sql . \' AND         


        

Answer 1

Instead of if else just use PHP ternary operator

     if (isset($_POST['statusID']))
{
  $statusID = $_POST['statusID'];
}
else
{
  $statusID = 1;

}

instead of that you can do:

 $statusID =  (isset($_POST['statusID'])) ? $_POST['statusID'] : 1;

The format of the ternary operator is: $variable = condition ? if true : if false

The beauty of it is that you will shorten your if/else statements down to one line and if compiler ever gives you errors, you can always go back to that line instead of 3 lines.
