pa cini se da $delete_array i nije niz...Prvi argument za foreach funkciju trebalo bi da bude niz...
uradi sledece:
echo $delete_array;
pa proveri sta je s tom varijablom

bas sam i to probao ali nepokazuje nista, a osim toga ako nesto dodajes u kategorijama onda kad ides na delete tada se brise ali ono sto je bio prije njega dodano ono ga nebrise, evo sta mi pokazuje:

Code:
Nothing to delete!

Pregledao sam ti kod i sa tri crtice (---) sam ti obelezio gde sam kod promenio. Sada treba da radi. Treba samo da izbrises te moje crtice.

Prva greska ti je bila sto si formu poceo na kraju tabele i nisi je zatvorio. Forma mora da pocne na pocetku tabele da bi ti mogao da radis sa promenjivama koje koristis na sajtu.

Druga greska ti je u case "brisi". Prvo treba da izvrsis $_POST['delete'] a tek onda da proveravas koja promenjiva postoji a koja ne, a ako ne postoji onda je kraj programa, ako postoji onda radi foreach komandu.

Treca greska koja mozda nije ni greska je kod <form action>. Dodao si GET varijablu (action) i dodeli joj vrednost brisi. Ovo ti ne treba u ovom kodu, jer u case "brisi" on zove $_POST['delete'] sto je name='Delete' na kraju forme. Posle metod='post' si stavio name='delete' sto je isto tako nepotrebno, osim ako hoces da izvrsis neku javascript komandu. Ali kako vidim, ovde to nije slucaj.

To je sve od mene. Ako nesto nije dobro, tu sam.

Code:

case "pregled":
  //if there is an ID given...
  if($_GET['id'])
  {
      //get the id, put it into a variable, cast to an INT
      //(for security purposes)
      $id = (int)$_GET['id'];
      $query = mysql_query("SELECT * FROM software WHERE kat_id = '$id' AND validen = '1'") or die(mysql_error());

      //if no results, show that there are no tutorials
      //for that category
      if(mysql_num_rows($query) == 0)
      {
          echo "Nema software vo ovaa Kategorija!";
      }
      //else, there is..show em

hvala ti puno, sada sve je ok, ali htio bi da te pitam jos nesto ako imas vremena da mi to objasnis malo,
u checkbox-u je pitanje jel product nov, e sad kod mene prikazuje sa broj ako je nov prikazuje 1 ako nije nov onda prikazuje 0, kako sad mogu napraviti na svaki product ako je nov da prikazuje NOVO, a ako nije onda da neprikazuje nista, i za kraj sa CD, oni su u optional, sta znaci ako izaberem cd sa slovima kao naprimer DVD 1, prikazuje mi po ID, treba mi kod za da preimenjujem to u slovima!
evo moja baza

baza.sql

Code:
CREATE TABLE `product` (
  `id` INT(250) NOT NULL AUTO_INCREMENT,
  `sifra` VARCHAR(25) NOT NULL,
  `naslov` VARCHAR(250) NOT NULL,
  `opis` TEXT NOT NULL,
  `kat_id` VARCHAR(25) NOT NULL,
  `cd_id` VARCHAR(25) NOT NULL,
  `novo` TINYINT(1) NOT NULL,
  `datum` VARCHAR(250) NOT NULL,
  `validen` TINYINT(1) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM;

CREATE TABLE `product_kategorija` (
  `id` INT(25) NOT NULL AUTO_INCREMENT,
  `kategorija` VARCHAR(250) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM;

CREATE TABLE `product_cd` (
  `id` INT(25) NOT NULL AUTO_INCREMENT,
  `cd` VARCHAR(250) NOT NULL,
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM;
