//variavel recebe de input html
$ssid = @$_POST['user']; 
 if(isset($_POST['enviar'])
{
  //deveria printar valor na tela
  echo $ssid;
}

The variable $ssid receives an input value, but when I click on the send button the value of the variable goes along with the page refresh as save the value of the variable to use after page refresh?

php is stateless, so each request is independent, not related to the previous one, because the attribute status is not maintained. Therefore Voce can store in the session as follows:

<?php 
// session_start inicia a sessão
session_start();
//variavel recebe de input html
$ssid = @$_POST['user']; 
$_SESSION['ssid'] = $ssid;

  • It didn’t even work with Session when you enter if(isset), the value goes missing

  • It worked, but I had to change the method from $_POST to $_GET

  • Show, if you had to change from POST to GET is because your form is sending as GET, I only suggested POST because as you put this in your example gave meet that your form was POST. I just didn’t understand why my answer wasn’t marked as the correct one and I answered it well before.

To be able to store the variable even after the page update, use $_SESSION.

To log into the file you are working = session_start();

$_SESSION['ssid'] = @$_POST['user']; // Aqui você está armazenando a sua varivel recebida na $_SESSION; 

 if(isset($_POST['enviar'])
{
  echo $_SESSION['ssid']; 

}

If you want to remove Session, unset($_SESSION['ssid is used']);

To learn more about Sessions, the PHP website has her manual https://www.php.net/manual/en/reserved.variables.session.php

  • it still didn’t work

  • It worked, but I had to change the method from $_POST to $_GET
