php - How to insert data using wpdb

Question

I have wriiten as following

$name="Kumkum";
$email="kumkum@gmail.com";
$phone="3456734567";
$country="India";
$course="Database";
$message="hello i want to read db";
$now = new DateTime();
$datesent=$now->format('Y-m-d H:i:s');    
global $wpdb;
$sql = $wpdb->prepare(
 "INSERT INTO `wp_submitted_form`      (`name`,`email`,`phone`,`country`,`course`,`message`,`datesent`) values ("
 $name, $email, $phone, $country, $course, $message, $datesent. ')")';

$wpdb->query($sql);

It's not working... It throws error... Please help me in correcting it.

Answer 1

Use $wpdb->insert().

$wpdb->insert('wp_submitted_form', array(
    'name' => 'Kumkum',
    'email' => 'kumkum@gmail.com',
    'phone' => '3456734567', // ... and so on
));

Addition from @mastrianni:

$wpdb->insert sanitizes your data for you, unlike $wpdb->query which requires you to sanitize your query with $wpdb->prepare. The difference between the two is $wpdb->query allows you to write your own SQL statement, where $wpdb->insert accepts an array and takes care of sanitizing/sql for you.
