Hello everybody again I'm tryin to resolve my issue poste in this topic -> Fetch data from Prestashop custom field I've have made a MySql query outside my class and now it works but i need to put the result in an array inside the class. I paste my code below: 

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT codice_target FROM customer";
$result = $conn->query($sql);


if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id_customer"]. " - Codice target: " . $row["codice_target"]."<br>";
    }
} else {
    echo "0 results";
}
$conn->close();

Then there is the class and the function i need to put the result from the query

class AdvancedExport extends Module
{

//other methods here...

        public function fputToFile($file, $allexportfields, $object, $ae)
        {
            if($allexportfields && $file && $object && $ae)
            {
                //one ready for export product
                $readyForExport = array();


                //put in correct sort order
                foreach ($allexportfields as $value)
                {
                    $object = $this->processDecimalSettings($object, $ae, $value);
                    $readyForExport[$value] = iconv("UTF-8", $ae->charset, $object[$value]);

                }

                // need to put mysql query result here inside $readyForExport['codice_target'];

                $this->counter[$readyForExport['id_order']] = (!empty($this->counter[$readyForExport['id_order']])) ? ++$this->counter[$readyForExport['id_order']] : 1; // try here
                $readyForExport['orderLine'] = $this->counter[$readyForExport['id_order']]; // and try here

                //print_r('The id_order is added: ' . $readyForExport['orderLine']); // see if it is added

                //echo '<pre>' . var_dump($readyForExport) . '</pre>';

                // modifiche === Dario === prezzo
                $newPrice = substr($readyForExport['product_price'], 0, strpos($readyForExport['product_price'], "."));
                $readyForExport['product_price'] = $newPrice;

                // === data

                $newDateAdd = new DateTime($readyForExport['date_add']);

            }
        }

Thanks far all done until now, Im really close to the goal.

回答1:

Array values initialized to $rtoclass variable outside the class, then passed to an AdvancedExport object through its method - $obj->set_arr_needed( $rtoclass );

On $obj->fputToFile() call, the needed array will automatically be available for use inside it via the variable $arr_needed_in.

Try:

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "dbname";


// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT codice_target FROM customer";
$result = $conn->query($sql);
$rtoclass = array();

if ($result->num_rows > 0) {
    // output data of each row
    while($row = $result->fetch_assoc()) {
        echo "id: " . $row["id_customer"]. " - Codice target: " . $row["codice_target"]."<br>";
        $rtoclass[] = $row;
    }
} else {
    echo "0 results";
}

$obj = new AdvancedExport();
$obj->set_arr_needed( $rtoclass );

$conn->close();

For the class:

class AdvancedExport extends Module
{

        //other methods here...

        private $arr_needed = array(); 

        public function set_arr_needed( $arr ) {    
            $this->arr_needed = $arr;
        }

        public function get_arr_needed() {  
            return $this->arr_needed;
        }

        public function fputToFile($file, $allexportfields, $object, $ae)
        {
            $arr_needed_in = $this->get_arr_needed(); // array needed already inside..

            if($allexportfields && $file && $object && $ae)
            {
                //one ready for export product
                $readyForExport = array();


                //put in correct sort order
                foreach ($allexportfields as $value)
