i'm trying to understand the best way to use Function's arguments in nested functions:
Here are my thoughts:
This is a bunch of functions i first declare to use them later in other functions:
//Habitaciones restantes
function rleft($from, $to, $room_type_id){
//Acceso a DB
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
//Hotel Room Data
$customroom = mysqli_query($conn, "SELECT * FROM hotel_room_type WHERE room_type_id = '$room_type_id'");
$customroomtotal = mysqli_num_rows($customroom);
$customroomData = mysqli_fetch_array($customroom);
$roominventory = $customroomData['room_type_inventory'];
//Obteniendo lista de disponibilidad
$customavailable = mysqli_query($conn, "SELECT * FROM booking_check_avilability WHERE room_type_id = '1' AND check_in_date = '$from' AND check_out_date = '$to'");
$customavailabletotal = mysqli_num_rows($customavailable);
mysqli_close($conn);
if($customavailabletotal > 0) {
while($customavailableData = mysqli_fetch_array($customavailable)) {
$inventariodisponible = $roominventory - $customavailableData['total_room'] -$customavailableData['blocked_inventory'];
}
} mysqli_free_result($customavailable);
mysqli_close(conn);
return $inventariodisponible;
}
//Creamos el array donde se almacenarán todos los dias entre las 2 fechas del cliente
function createRange($startDate, $endDate) {
$tmpDate = new DateTime($startDate);
$tmpEndDate = new DateTime($endDate);
$outArray = array();
do {
$outArray[] = $tmpDate->format('Y-m-d');
} while ($tmpDate->modify('+1 day') < $tmpEndDate);
return $outArray;
}
//creamos un array donde se almacenará la dispo para cada una de las fechas del cliente
function inout($room_type_id){
require ('/some-path/getparam.php');
$datearray = createRange("$fromdate", "$todate", "$room_type_id");
$arraycount = count($datearray);
$leftarray = array();
foreach ($datearray as $value) {
$from = $value;
$to = date('Y-m-d',strtotime($value . "+1 days"));
$leftarray[] = rleft($from, $to);
}
return $leftarray;
}
//Room or Rooms?
function sp(){
require ('/some-path/getparam.php');
if (rleft($fromdate, $todate, $room_type_id) == 1) {
$rq = "room";
}
else{
$rq = "rooms";
}
return $rq;
}
//Habitaciones restantes
function availablerooms(){
//Acceso a DB
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
$keyarray = createrange($fromdate, $todate);
$valuearray = inout();
$joinarray = array();
foreach ($keyarray as $i => $key) {
$joinarray[$key] = $valuearray[$i];
}
return $joinarray;
}
So here is the main function:
//Función para checkar si hay disponibilidad para las fechas seleccionadas
function next($room_type_id){
//basic include files
require('/some-path/database.php');
//url parameters
require ('/some-path/getparam.php');
//Checkamos que haya dispo
$inoutarray = inout("$room_type_id");
foreach ($inoutarray as $value) {
if ($value < $rooms) {
echo "Sorry NO rooms available!"; //no hay habitaciones disponibles
echo "</br>";
?>
<!-- Escondemos el botón de submit de la habitación -->
<style type="text/css">.bromeliabtn{
display:none!important;
}</style>
<!-- Cambiamos el estilo del msj -->
<style type="text/css">.bromeliadsbl span{
color: #c58e21!important;
font-size: 20px!important;
line-height: 25px!important;
}</style>
<?php
$cond = true;//asignamos un valor a $cond
break; // si match entonces termina el loop
}else{
unset($cond);
$cond = false;//si hay disponibilidad entonces sumar 1 a $cond
}
}
//si las fechas tienen dispo entonces seguimos :)
if ($cond == false) {//si $cond es 2 entonces podemos seguir
allowed();
}
}
//Esta función nos permite obtener los precios tanto de temporada como normales de acuerdo a la fecha especificada.
function allowed($room_type_id){
//Acceso a la base de datos
require('/some-path/database.php');
require ('/some-path/getparam.php');
//Creamos la consulta para precios por temporada
$sql = "SELECT `seasonal_price`"
. " FROM `hotel_seasonal_price`"
. " WHERE `room_type_id` = '$room_type_id'"
. " AND `room_person` = '$Room1'"
. " AND `seasonal_price_deleted` = '0'"
. " AND '" . $fromdate . "' = seasonal_from"
//. " AND '" . $currentdate . "' = 'seasonal_to'"
. " LIMIT 1";
$result = mysqli_query($conn, $sql) or die(mysqli_error());
if (mysqli_num_rows($result) != 0) {
$seasonalprice = mysqli_query($conn, $sql);
if (!$seasonalprice) {
die('Could not get data: ' . mysqli_error());
} else {
while ($standard2 = mysqli_fetch_assoc($seasonalprice)) {
//echo "$ " . $standard2['seasonal_price'] . "";
$stdrd = $standard2['seasonal_price'];
echo "$ ";
echo number_format((float)($stdrd + ((10*$stdrd)/100)), 2, '.', ''); //sumamos el porcentaje de descuento que luego sera restado en el precio principal
echo " ";

So here is my doubt, the argument: $room_type_id is the only one wich i need to change in the main function to get what i want from every room in the database, and each function should be used with that variable as parameter to change such information... my question is, if i define the room type id once in the main variable, will this be also accepted and used for all the others functions as a value for this argument? lets say:
function next("7");
Will the number 7 be used for all the other nested functions inside this function as a value for the same argument?
Thanks in advance for your help.
