W funkcji reserve() dodaje do zmiennej tablicowej reservationId
wartosci potrzebne mi takze w funkcji delete().

Wydawalo mi sie ze nadajac zmiennej wartosc w jednej funkcji
bede mogla ja odczytac rowniez w innej funkcji tej samej klasy.
Tak jednak nie jest

i w innej funkcji odczytuje ja jako tablice pusta...

Z tego wzgledu mam pytanie jak przekazac reservationId z jednej do drugiej funkcji w klasie?

[PHP] pobierz, plaintext 
<?php
// funkcja reserve
 
(...)
 
			$this->messages[] = $this->msg;
 
			$this->reservationId[] = $id;  
		}			  
		return $this->messages;
	}
	public function delete()
	{
		$items = count($this->reservationId);
 
(...)
?>

a napewno na poczatku zdeklarowales ta zmienna

Tak zadeklarowalam

Zauwazylam jeszcze jedna rzecz...
Kiedy mam zadeklarowana zmienna $p w konstruktorze jako 0
dalej zmieniam ja w funkcji reserve na 5
to w funkcji delete ma ona znow wartosc 0 !
Zapewne to samo dzieje sie z moja tablica reservationId...
?
Jak wiec zatrzymac wartosci tej tablicy dla innych funkcji ?

[PHP] pobierz, plaintext 
<?php
public $reservationId;
 
public function __construct()
	{
	$this->reservationId = array();
(...)
}

Pokaż kod klasy z funkcjami o których mówisz i przykład jak to wykorzystujesz/testujesz.

U mnie dziala, skleilem cos takiego na szybko

[PHP] pobierz, plaintext 
<?php
class whatever
{
public $reservationId;
 
public function __construct()
	{
	$this->reservationId = array();
	}
 
public function reserve()
	{
			$this->reservationId[] = 15;
	}
 
	public function delete()
	{
		echo( count($this->reservationId) );
	}
}
 
$w = new whatever;
$w->reserve();
$w->delete();
?>

Moze zapomniales dodac () przy wywolywaniu funkcji ?

Dziekuje za pomoc.
Jednak ja nadal nie wiem co stalo sie z moim kodem

Klasa wyglada mniej wiecej tak:

[PHP] pobierz, plaintext 
<?php
class Reservation
{
	public $msg;
	public $messages;
	public $reservationId;
 
 
	public function __construct()
	{
		$this->msg = NULL;
		$this->messages = array();
		$this->reservationId = array();
	}
 
 
	public function reserve()
	{	
 
		$items = count($this->ObjSelect);
		$i = 0;
 
		while ($i < $items)
		{
 
			if ($k)
			{
...
			}
 
			$this->messages[] = $this->msg;
			$this->reservationId[] = $id;			// zwraca tablice wszystkich id
			$i++;
		}
		return $this->messages;
	}
 
	public function delete()
	{								
		$items = count($this->reservationId);
		print_r($items);		// wyswietla 0 :(
		exit;
 
		$i = 0;
		while ($i < $items)
		{
			mysql_query ("DELETE FROM `reservation` WHERE `Reservation_id` = '".$this->reservationId[$i]."' ");
			$i++;
		}
 
	}
 
 
 
 
 
}
 
 
 
 
?>
[PHP] pobierz, plaintext

A wywolanie funkcji tak:

[PHP] pobierz, plaintext 
<?php
if(isset($_POST['delete']))
	{
	$oReservation->delete();
	}
?>
[PHP] pobierz, plaintext

Jednak mam 3 formularze wysylane po kolei do jednej klasy.
Czy to moze byc przyczyna ze zeruja mi sie wartosci zmiennych?

Puciek

A wywolales funkcje reserve ?
Daj caly kod bo w zgaduj zgadule bawic mi sie nie chce

Dziekuje za probe pomocy

Ponizej wklejam kod klasy i pliku z wywolaniami funkcji:

Ale juz chyba wiem co jest przyczyna...
Wywoluje 2 razy formularz i pewnie przy drugim wywolaniu ponawia sie wywolanie new Reservation i zeruje wszystkie wartosci.

Jak mozna to zrobic inaczej?
