Jquery自动完成在一行中显示来自mysql的两行

Question

I have a mysql table with multiple rows

ID, country, city, region

I have a search working with jquery-ui autocomplete, which currently autocompletes city searches like so:

if (isset($_GET['term'])){
    $return_arr = array();

    try {
        $conn = new PDO("mysql:host=".DB_SERVER.";port=8889;dbname=".DB_NAME, DB_USER, DB_PASSWORD);
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        $stmt = $conn->prepare('SELECT city,country FROM location WHERE city LIKE :term LIMIT 10');
        $stmt->execute(array('term' => '%'.$_GET['term'].'%'));

        while($row = $stmt->fetch()) {
            $return_arr[] =  $row['city'];

        }

    } catch(PDOException $e) {
        echo 'ERROR: ' . $e->getMessage();
    }



    echo json_encode($return_arr);
}

I would like to display the country next to the city, so Los Angeles would become Los Angeles, US

Answer 1

In php you can append a string by using a '.' For example:

$mystring = 'part one' . 'part two';

echo $mystring; //-> will product: part onepart wo

You can also let php interpret a string to delimiting with '"' (double quotes)

$myvar = "boat";
$mystring = "One day I'll buy a {$myvar}";

echo $mystring; //-> will produce: One day I'll buy a boat

The below should work ok. Good luck!

if (isset($_GET['term'])){
    $return_arr = array();

    try {
        $conn = new PDO("mysql:host=".DB_SERVER.";port=8889;dbname=".DB_NAME, DB_USER, DB_PASSWORD);
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

        $stmt = $conn->prepare('SELECT city,country FROM location WHERE city LIKE :term LIMIT 10');
        $stmt->execute(array('term' => '%'.$_GET['term'].'%'));

        while($row = $stmt->fetch()) {
            $return_arr[] =  $row['city'] . ', ' . $row['country'];

        }

    } catch(PDOException $e) {
        echo 'ERROR: ' . $e->getMessage();
    }



    echo json_encode($return_arr);
}

Another alternative way to solve this would be to append the string in your SQL

SELECT CONCAT(city, ', ', country) AS location FROM location WHERE city LIKE :term LIMIT 10
