Question

我已经完成了电话簿所需的一切。但我唯一不能做的就是这个。

我需要这个表单有2个按钮，它有一个将新用户添加到数据库中但我需要另一个按钮，将新用户详细信息通过电子邮件发送到电子邮件地址。我需要先显示电子邮件按钮。然后在发送之后必须出现提交按钮。我花了大约2个小时浏览有关mail（）和邮件功能的不同教程，但我不明白。我仍然是html和php的新手。

到目前为止，使用一个工作按钮来说明我的代码。

Answer 1

您可以使用两个不同的提交按钮。看一下下面的例子：

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST' && isset($_POST['submit'])) {
    switch ($_POST['submit']) {
        case 'one':
            echo "You submitted using the first button";
            break;
        case 'two':
            echo "You submitted using the second button";
            break;
    }
}
?>
<form method="POST" action="<?= $_SERVER['PHP_SELF']; ?>">
    <input type="submit" name="submit" value='one' />
    <input type="submit" name="submit" value='two' />
</form>

这是在同一页面中执行两个操作的更高级示例。这将需要多次重定向。

<?php
session_start();

if (isset($_POST['submit']) && $_POST['submit'] == 'save') {
    // Insert into the database

    // Add the $_POST data to a session
    $_SESSION['postdata'] = $_POST;
    // Unset the POST
    unset($_POST);

    // Redirect to same page
    header("Location: ".$_SERVER['PHP_SELF']);
    exit;
} elseif (isset($_POST['submit']) && $_POST['submit'] == 'email') {
    // Send your email
    mail(...);
    unset($_SESSION['postdata']);
    // Redirect to same page and add another user
    header("Location: ".$_SERVER['PHP_SELF']);
    exit;
}
?>

<?php if (!isset($_SESSION['postdata'])): ?>
<form method="POST" action="<?= $_SERVER['PHP_SELF']; ?>">
    <input type="text" name="username" />
    <input type="submit" name="save" />
</form>
<?php else: ?>
<form method="POST" action="<?= $_SERVER['PHP_SELF']; ?>">
    The user with username <?= $_SESSION['postdata']['username']; ?> has been saved.
    <p>Do you want to submit an email as well?</p>
    <input type="submit" name="mail" />
</form>
<?php endif; ?>

当您将表单发布回自身时，如果您设置一个带有隐藏表单字段的标志以指示表单已提交，则会有所帮助。然后，只有在提交表单后，才能在页面上运行特定代码。这可以验证数据并显示“发送电子邮件”按钮。然后，您可以设置第二个标志，在回发时使表单显示添加用户到数据库按钮。总之，如果您要使用回发本身，则需要引入一些隐藏字段标志来更好地控制表单。

另一种方法是将表单发布到另一个脚本进行处理，这样可以更好地控制顺序按钮的显示。

Answer 3

如果你给每个人一个名字，那么点击的名字将作为任何其他输入发送。

<input type="submit" name="first_button" value="Click me">
<input type="submit" name="second_button" value="Click me">

if (isset($_POST['first_button'])) {
    //first button action
} else if (isset($_POST['second_button'])) {
    //second buttonaction
} else {
    //no button pressed
}
