Question

我使用以下方法消除了多个步骤的执行，甚至消除了单独的变量。

if($payment === 'Completed'){
    session_start();
    unset($_SESSION['datos_form']);
    unset($_SESSION['__step__']);
    unset($_SESSION['formid']);
    unset($_SESSION['sPaso']);
    unset($_SESSION['Pending']);
    unset($_SESSION['p']);
    unset($_SESSION['step']);
    unset($step);
}

但是使用unset函数并不能消除这些步骤

我保存步骤的PHP文件

<?php
    session_start();
    $step =  isset($_GET['step']) ?  $_GET['step'] : 1;
    $_SESSION['datos_form'] = $_POST;

    $datosForm = (isset($_SESSION['datos_form']) && is_array($_SESSION['datos_form'])) ? $_SESSION['datos_form'] :array();
    $sPaso = isset($datosForm['__step__']) ? $datosForm['__step__'] : 1;
    $step = isset($step) ? $step : $sPaso;
    $_SESSION['datos_form']['__step__'] = $step;

    header('Content-Type: application/json');

    $json =  array(
        'radio'     => $radio,
        'step'      => $step
    );

    echo json_encode($json);
?>

我执行了var_dump ($ _ SESSION);和print_r ($ GLOBALS);，获得以下信息：

[_SESSION] => Array
    (
        [datos_form] => Array
            (
                [__step__] => 3
            )

        [4b228aaae2a6a7ce403bc4ecbc481de6] => ../libro.pdf
        [cart] => Array
            (
                [0] => 11
            )

        [qty] => Array
            (
                [0] => 1
            )

        [formid] => 64da7c62c643f40684f573acffb144eba6bfaf63
        [id_user] => 1
    )

)

使用var_dump：

array(6) { ["datos_form"]=> array(1) { ["__step__"]=> string(1) "3" }

当我转到步骤1时，[__step__] => 1 string(1) "1"获得了以下更改：

[datos_form] => Array
    (
        [__step__] => 1
    )
array(6) { ["datos_form"]=> array(1) { ["__step__"]=> string(1) "1" }

当我转到步骤2时，[__step__] => 2 string(1) "2"获得了以下更改：

[datos_form] => Array
    (
        [__step__] => 2
    )
array(6) { ["datos_form"]=> array(1) { ["__step__"]=> string(1) "2" }

Answer 1

您正在将setState()设置为__step__的直接后代，但它是$_SESSION的子代

要取消设置，您需要$_SESSION[datos_form]
