Remove data from array using php input

  • 772

What would it be like to delete data in an array using input? All this with the session variable to have to make a hidden array so that when refreshing I don't delete it. I understand that it would be something like that, even though it's wrong since it doesn't work

 if(isset($_POST['eliminar'])){
    $verboESP = $_POST['verboESP'];


        unset($verbosOculto[$_POST['verboESP']]);
        $verbosOculto = array_values($verbosOculto);



        header('Location: diccionario.php'); 
    }

with the input

<input type="text" name="verboESP">

        <input type="submit" name="eliminar">
php

    Unfortunately the code you shared in the previous question is missing (you deleted the question) to solve this question.

    You keep insisting on working with a local variable, $verbosOculto, instead of working with $_SESSION['verbosOculto'].

    You should do:

    /* Imagino que habrás iniciado previamente el uso de variables de sesión */
session_start();
if (isset($_POST['eliminar'])){
  /* Esto no es necesario, deja la mala costumbre de usar variables intermedias */
  $verboESP = $_POST['verboESP'];
  unset($_SESSION['verbosOculto'][$_POST['verboESP']]);
  /* Eso que haces no sirve para nada porque se perderá al finalizar el script */
  $verbosOculto = array_values($verbosOculto);
  header('Location: diccionario.php'); 
  /* Debes finalizar la ejecución del script actual */
  exit();
}
