大家好，我正试着在这个主题中解决我的问题 - ＆gt; Fetch data from Prestashop custom field 我已经在我的类之外创建了一个MySql查询，现在它可以工作，但我需要将结果放在类中的数组中。我粘贴下面的代码：
$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";
}
$conn->close();
然后我需要将类和函数放入查询结果
class AdvancedExport extends Module
{
//other methods here...
public function fputToFile($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']);
$readyForExport['date_add'] = $newDateAdd->format('d/m/Y');
// aggiungo 21 giorni - 3 settimane - alla data di acquisto
$date_mod = clone $newDateAdd;
$date_mod->add(new DateInterval('P21D'));
$readyForExport['delivery_date'] = $date_mod->format('d/m/Y');
// === data invoice
$newDateInvoice = clone $newDateAdd;
$readyForExport['invoice_date'] = $newDateAdd->format('d/m/Y');
//scambio l'id customer con il codice_target
//$readyForExport['codice_target'] = 8989;
$textTarget = (string)$readyForExport['codice_target'];
$readyForExport['id_customer'] = $textTarget;
// aggiungo gli zeri davanti al customer id
$id_count = strlen($readyForExport['id_customer']);
if ($id_count == 1) {
$newCustomer = "0000000".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}elseif ($id_count == 2) {
$newCustomer = "000000".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}elseif ($id_count == 3) {
$newCustomer = "00000".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}elseif ($id_count == 4) {
$newCustomer = "0000".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}elseif ($id_count == 5) {
$newCustomer = "000".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}elseif ($id_count == 6) {
$newCustomer = "00".$readyForExport['id_customer'];
$readyForExport['id_customer'] = $newCustomer;
}
// elaboro lo SKU
$textSku = (string)$readyForExport['product_name'];
$newSku_1 = $readyForExport['product_name'];
$newSku_1 = substr($newSku_1,0,4);
$newSku_2 = "/".substr($textSku,-4,4);
$newSku_tot = $newSku_1.$newSku_2;
$newSku_tot = str_replace(' ', '', $newSku_tot);
$newSku_tot = str_replace('-', '', $newSku_tot);
$newSku_tot = str_replace('co', '', $newSku_tot);
$newSku_tot = str_replace('e', '', $newSku_tot);
$newSku_tot = str_replace('r', '', $newSku_tot);
$readyForExport['product_name'] = $newSku_tot;
// aggiungo un campo fisso
$readyForExport['causale'] = "NR";
// aggiungo un campo fisso
$readyForExport['ORCL'] = "ORCL";
//$readyForExport['G'] = "";
$readyForExport['J'] = "";
$readyForExport['K'] = "";
$readyForExport['L'] = "";
$readyForExport['M'] = "";
$readyForExport['N'] = "";
$readyForExport['P'] = "";
$readyForExport['Q'] = "";
$readyForExport['R'] = "30";
$index_arr=array("id_customer","date_add","ORCL","product_name","causale","product_quantity","product_price","delivery_date","id_order","J","K","L","M","N","orderLine","P","Q","R");
//riordino i campi in base a come li dispongo nella variabile $index_arr
$arr_t=array();
foreach($index_arr as $i=>$v) {
foreach($readyForExport as $k=>$b) {
if ($k==$v) $arr_t[$k]=$b;
}
}
$readyForExport=$arr_t;
//write into csv line by line
fputcsv($file, $readyForExport, $ae->delimiter, $ae->separator);
}
}
感谢迄今为止所做的一切，我真的很接近目标。
答案 0 :(得分：0)
数组值在类外部初始化为$rtoclass变量，然后通过其方法传递给AdvancedExport对象 - $ obj-＆gt; set_arr_needed( $rtoclass );
在$obj->fputToFile()调用时，所需的数组将通过变量$arr_needed_in自动在其中使用。
尝试：
$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();
对于班级：
