【问题描述】：

我正在创建一个包含 HTML 表单的网站，该表单具有一个空白操作，该操作指向表单所在的同一网页，以便可以使用 PHP 处理该表单。 PHP 代码没有被执行。你能看看我的代码并告诉我哪里出了问题吗？

<?php
if (isset($_POST['reportsubmit'])) {
    $radio = $_POST['customer'];
    if ($radio == 'customer') {
        $redirect = 'Click <a href="#customer">here</a> to continue on with the form';
        header('Location: #redirect');
    } else if ($radio == 'item') {
        $redirect = 'Click <a href="#item">here</a> to continue on with the form';
        header('Location: #redirect');
    } else if ($radio == 'department') {
        $redirect = 'Click <a href="#department">here</a> to continue on with the form';
        header('Location: #redirect');
    } else if ($radio == 'person') {
        $redirect = 'Click <a href="#person">here</a> to continue on with the form';
        header('Location: #redirect');
    }
    exit;
} else if (isset($_POST['customersubmit'])) {
    //process form
    //redirect
    exit;
} else if (isset($_POST['itemsubmit'])) {
    //process form
    //redirect
    exit;
} else if (isset($_POST['departmentsubmit'])) {
    //process form
    //redirect
    exit;
} else if (isset($_POST['personsubmit'])) {
    //process form
    //redirect
    exit;
}
?>

【问题讨论】：

$_POST['reportsubmit'] 是真的吗？另外，我很确定您无法重定向到锚点。您需要指定页面的实际 URL。
一旦你设置了header('Location: ...');，页面就不会被进一步处理，它会尝试重定向。
尝试print_r($_POST) 验证是否设置了$_POST['reportsubmit']；
@leonardude 你喜欢用header('Location: #redirect')做什么？ #redirect 是一个 html 锚点，不是要重定向的页面...

【解决方案1】：

尝试下一步：

1) 对于所有形式：

将<form action="" method="post"> 替换为<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"], ENT_QUOTES, "utf-8"); ?>" method="post">

2) 对于所有重定向：

$findHttp = isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] != 'off' ? 'https' : 'http';
header('Location: '.$findHttp.'://'.$_SERVER["HTTP_HOST"].'/');
exit;

3) 检查 POST 请求 - var_dump($_POST); 并找到当前适用于该请求的“if”块。

【讨论】：

您应该使用htmlentities() 清理$_SERVER['self'] 回声。检查this SO question。

【解决方案2】：

最佳做法是指定目标网址。如果你想自我总结试试这个

<form action="<?php echo htmlentities($_SERVER['PHP_SELF']) ?>">

您应该使用htmlentities() 清理该回声。检查this SO question。
