[mczgikv]

\[code\]$roidInfo = '';$nomeDominio =''; if (isset($_GET['infoDominio'])) { $nomeDominio = filter_input(INPUT_GET, 'nomeDominio', FILTER_SANITIZE_STRING); $dominioVo->setNome($nomeDominio); try { ... $roidInfo = isset($infoDominio['roid']) ? $infoDominio['roid'] : ''; } catch (EppCommandsExceptions $e) { ... } //all well here, I get the dump with values: //var_dump($nomeDominio); //var_dump($roidInfo); } if (isset($_POST['atualizarDominio'])) { var_dump($nomeDominio); //dump "" var_dump($roidInfo); //dump ""\[/code\]On the above excerpt I lost the value of $nomeDominio and $roidInfo but I don't understand why. Can I have your help to find out why is this happening?UPDATEHere is, the exact same issue, but by using SESSIONS:\[code\]<?php session_start(); ?><?php $roidInfo = ''; $nomeDominio =''; if (isset($_GET['infoDominio'])) { $nomeDominio = '123'; try { //... $roidInfo = '456'; $_SESSION['nomeDominio'] = $nomeDominio; $_SESSION['roidInfo'] = $roidInfo; //retrieving the values. OK. var_dump($_SESSION['roidInfo']); var_dump($_SESSION['nomeDominio']); } catch (EppCommandsExceptions $e) { //... } } if (isset($_POST['atualizarDominio'])) { //retrieving index undefined. not ok. var_dump($_SESSION['nomeDominio']); var_dump($_SESSION['roidInfo']); //all the rest... runs }?>\[/code\]Thanks in advance,MEM
