My Insert Function Are Inserting Empty Values In Database

[thugsr]

Hi everybody,

i have class with some variables and insert function, but when i call insert function in database are inserted empty values, just id (AUTO INCREMENT) has value other cells are emtpy...

My class is:

<?php 


include ('db_fns.php');


class preduzece {

         public $naziv_preduzeca;
         public $sifra_mesta;
         public $ulica;
         public $broj;
         public $opis;
         public $sifra_delatnosti;
         public $sifra_usluge;
         public $aktivno;

public function dodaj_preduzece ($preduzece)

        {

  $query = "INSERT INTO preduzece (naziv_preduzeca, sifra_mesta, ulica, broj, opis, sifra_delatnosti, aktivno) VALUES 
  ('$preduzece->naziv_preduzeca','$preduzece->sifra_mesta','$preduzece->ulica','$preduzece->broj',
'$preduzece->opis','$preduzece->sifra_delatnosti','$preduzece->aktivno')";


  $result = mysql_query($query) or die("Doslo je do greske prilikom unosa preduzeca:" .mysql_error());


         // insert

 }
}
?>

And in other page i use it (have form from witch i collect values for db):

include("scripts/preduzece_fns.php")
$firma=new preduzece() ;
$firma->ulica=$_POST['ulica'];
$firma->broj=$_POST['broj'];
$firma->ulica= mysql_real_escape_string( $firma->ulica );
$firma->broj= mysql_real_escape_string( $firma->broj );
$firma->naziv_preduzeca = $_POST["naziv_preduzeca"];
$firma->naziv_preduzeca = mysql_real_escape_string( $firma->naziv_preduzeca );
$firma->sifra_mesta = $_POST["mesto"];
$firma->opis = $_POST["opis"];
$firma->opis= mysql_real_escape_string( $firma->opis );
$firma->sifra_delatnosti = $_POST["delatnost"];
$firma->aktivno = $_POST["aktivno"];
$firma->dodaj_preduzece();

when i echo $firma->naziv_preduzeca or anything else values are collected from form, only when i call function dodaj_preduzece something goes wrong...

Does anybody know why this is happening?

Ps sorry for grammar errors if i have it (I am from Serbia )

change all instances of $preduzece-> to $this-> and remove $preduzece from between the parenthesis of the function decleration. Then I recomend you go do some more learning on classess and objects.
