quering a database using mysql/php

[sarah333]

i want to display data in a table based on the user selection from a form (on a previous page).

my query isnt working:

$sth = $conn->prepare ('SELECT * FROM ROUTE WHERE ORIGIN = $ORIG');

the $ORIG is the value of the options inside the drop down list. (its the value of one option in the form on the previous page)

it’s not working because prepared statements don’t work like that.

example usage (PDO):

$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$stmt = $conn->prepare('SELECT * FROM ROUTE WHERE ORIGIN = ?');
// assuming string type parameter
$stmt->bindValue(1, $ORIG, PDO::PARAM_STR);
$stmt->execute();
foreach ($stmt as $row) {
    // do something with $row
}
