设置为HTML表单的操作时，不会执行PHP代码

[英]PHP code isn't being executed when set as the action for an HTML form

问题描述

I'm creating a website that has HTML forms that have a blank action that leads to the same web page that the form is on so that the form can be processed with PHP. 我正在创建一个网站，该网站具有HTML表单，该表单具有空白动作，该空白动作会导致该表单所在的网页相同，以便可以使用PHP处理该表单。 The PHP code isn't being executed. PHP代码未执行。 Can you look over my code and tell me what's wrong? 您能查看一下我的代码并告诉我出什么问题了吗？ 

<?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;
}
?>

Try the next step: 尝试下一步：

1) For all forms: 1）对于所有形式：

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

2) For all redirect: 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) Check POST request - var_dump($_POST); 3）检查POST请求var_dump($_POST); and find current 'if' block which work with that request. 并找到适用于该请求的当前“ if”块。

It's a best practice to specify the destination URL. 最佳做法是指定目标URL。 If you want to sumbit to itself try this 如果你想自己总结一下，试试这个 

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