Call to undefined method mysqli_stmt::get_result

Here's my code:

include 'conn.php';
$conn = new Connection();
$query = 'SELECT EmailVerified, Blocked FROM users WHERE Email = ? AND SLA = ? AND `Password` = ?';
$stmt = $conn->mysqli->prepare($query);
$stmt->bind_param('sss', $_POST['EmailID'], $_POST['SLA'], $_POST['Password']);
$stmt->execute();
$result = $stmt->get_result();

I get the error on last line as: Call to undefined method mysqli_stmt::get_result()

Here is the code for conn.php:

define('SERVER', 'localhost');
define('USER', 'root');
define('PASS', 'xxxx');
define('DB', 'xxxx');
class Connection{
    /**
     * @var Resource 
     */
    var $mysqli = null;

    function __construct(){
        try{
            if(!$this->mysqli){
                $this->mysqli = new MySQLi(SERVER, USER, PASS, DB);
                if(!$this->mysqli)
                    throw new Exception('Could not create connection using MySQLi', 'NO_CONNECTION');
            }
        }
        catch(Exception $ex){
            echo "ERROR: ".$e->getMessage();
        }
    }
}

If I write this line:

if(!stmt) echo 'Statement prepared'; else echo 'Statement NOT prepared';

It prints 'Statement NOT prepared'. If I run the query directly in the IDE replacing ? marks with values, it works fine. Please note that $conn object works fine in other queries in the project.

Any help please.......

Solution 1:

Please read the user notes for this method:

http://php.net/manual/en/mysqli-stmt.get-result.php

It requires the mysqlnd driver... If it isn't installed on your webspace you will have to work with bind_result() & fetch()!

Solution 2:

So if the MySQL Native Driver (mysqlnd) driver is not available, and therefore using bind_result and fetch instead of get_result, the code becomes:

include 'conn.php';
$conn = new Connection();
$query = 'SELECT EmailVerified, Blocked FROM users WHERE Email = ? AND SLA = ? AND `Password` = ?';
$stmt = $conn->mysqli->prepare($query);
$stmt->bind_param('sss', $_POST['EmailID'], $_POST['SLA'], $_POST['Password']);
$stmt->execute();
$stmt->bind_result($EmailVerified, $Blocked);
while ($stmt->fetch())
{
   /* Use $EmailVerified and $Blocked */
}
$stmt->close();
$conn->mysqli->close();

Solution 3:

Your system is missing the mysqlnd driver!

If you are able to install new packages on your (Debian/Ubuntu-based) server, install the driver:

sudo apt-get install php5-mysqlnd

and then restart your web server:

sudo /etc/init.d/apache2 restart

Solution 4:

With PHP version 7.2 I just used nd_mysqli instead of mysqli and it worked as expected.

Steps to enable it into godaddy hosting server-

1. Login to cpanel.
2. Click on "Select PHP version".
3. As provided the snapshot of the latest configurations uncheck "mysqli" and enable "nd_mysqli".

Solution 5:

for those searching for an alternative to $result = $stmt->get_result() I've made this function which allows you to mimic the $result->fetch_assoc() but using directly the stmt object:

function fetchAssocStatement($stmt)
{
    if($stmt->num_rows>0)
    {
        $result = array();
        $md = $stmt->result_metadata();
        $params = array();
        while($field = $md->fetch_field()) {
            $params[] = &$result[$field->name];
        }
        call_user_func_array(array($stmt, 'bind_result'), $params);
        if($stmt->fetch())
            return $result;
    }

    return null;
}

as you can see it creates an array and fetches it with the row data, since it uses $stmt->fetch() internally, you can call it just as you would call mysqli_result::fetch_assoc (just be sure that the $stmt object is open and result is stored):

//mysqliConnection is your mysqli connection object
if($stmt = $mysqli_connection->prepare($query))
{
    $stmt->execute();
    $stmt->store_result();

    while($assoc_array = fetchAssocStatement($stmt))
    {
        //do your magic
    }

    $stmt->close();
}
