pessoal estou com uma duvida

tipo tenho uma pagina que ela abre recebendo o id de uma outra pagina anterior

abre assim

paginaseraaberta.php?endereco=&id={$linha->id}

então ela abre com o id passado

que é

?endereco=&id={$linha->id}

mais tipo quando tento fazer upload da imagem ela atualiza a mesma pagina e fica sem passar o id :(

como eu altero ? http://forum.imasters.com.br/public/style_emoticons/default/ermm.gif

para quando eu for fazer uploads das imagens esta pagina se atualiza e repassa o ?endereco=&id={$linha->id} para ela mesmo :huh:

se atualizar sem perder o id

estou achando que é algo haver com o

="<?php echo $_SERVER["PHP_SELF"];?> "method="post">la no final da pagina

 :(

e esse é o codico da pagina que é paginaseraaberta.php

<?php
 error_reporting (E_ALL ^ E_NOTICE);
session_start();
include "Config.php";

 extract($_GET);

 $sql1 = "SELECT * FROM produtos WHERE id='$id'";
 $q = mysql_query( $sql1 );
 while ($linha =mysql_fetch_object( $q)){

 ?>
<?php

/* * * */

//only assign a new timestamp if the session variable is empty

if (!isset($_SESSION['random_key']) || strlen($_SESSION['random_key'])==0){
 $_SESSION['random_key'] = strtotime(date('Y-m-d H:i:s')); //assign the timestamp to the session variable
	$_SESSION['user_file_ext']= "";
}
