Can you please tell me what is it mean by this line, Please i am new to PHP.
$data["id_city"] = $_POST["city"];

	///// default multilanguage field for select
	$field_name = $multi_lang->DefaultFieldName(); 

////////// settings
$strSQL = "select value, name from ".SETTINGS_TABLE." where name in ( 'min_age_limit', 'max_age_limit','zip_letters', 'zip_count') ";
$rs = $dbconn->Execute($strSQL);
while(!$rs->EOF){
	$settings[$rs->fields[1]] = $rs->fields[0];
	$rs->MoveNext();
}
if($err){
	$form["err"] = $err;
	$data["fname"] = $_POST["fname"];
	$data["sname"] = $_POST["sname"];
	$data["login"] = $_POST["login"];
	$data["email"] = $_POST["email"];
	$data["gender"] = $_POST["gender"];
	$data["id_country"] = $_POST["country"];
	$data["id_city"] = $_POST["city"];
	$data["age_min"] = intval($_POST["age_min"]);
}

Thank you very much for the help.

It puts the value of the 'city' element in the $_POST array into the 'id_city' element in the $data array.

Thank you very much, How can i find the function which is filling the _Post array, i would like to add a new item to it called areacode. I have already added the field in the table, But on front end i want to add the changes:

I have the following code:

///// default multilanguage field for select
$field_name = $multi_lang->DefaultFieldName(); 

////////// settings
$strSQL = "select value, name from ".SETTINGS_TABLE." where name in ( 'min_age_limit', 'max_age_limit','zip_letters', 'zip_count') ";
$rs = $dbconn->Execute($strSQL);
while(!$rs->EOF){
	$settings[$rs->fields[1]] = $rs->fields[0];
	$rs->MoveNext();
}
if($err){
	$form["err"] = $err;
	$data["fname"] = $_POST["fname"];
	$data["sname"] = $_POST["sname"];
	$data["login"] = $_POST["login"];
	$data["email"] = $_POST["email"];
	$data["gender"] = $_POST["gender"];
	$data["id_country"] = $_POST["country"];
	$data["id_city"] = $_POST["city"];

the following functions are in class multi_lang

	function MultiLang($config, $dbconn){
		$this->config = $config;
		$this->dbconn = $dbconn;
	}

function DefaultFieldName(){
	return "lang_".$this->config["default_lang"];
}

Thank you.
