提交表格给自己

Question

目前，我有一个带有输入（文本）的表单和一个提交表单的按钮。

表单发布到'submit.php'。我希望将表单发布到与表单相同的页面。

我该怎么做？

<form action="submit.php" method="POST">
    <input type="text" class="emailField" placeholder="email address" name="email" />
    <button type="submit">
        <div class="submit" />
    </button>
</form>

submit.php

<?php
    mysql_connect('localhost', '', '') or die('unable to connect');
    mysql_select_db('') or die('unable to select db');
    $query = mysql_query("");
    if (mysql_num_rows($query) > 0) {
        exit("You have already subscribed!");
    }
    else {
        mysql_query("") or die(mysql_error());
        exit("You have successfully subscribed!");
    }

?>

我认为你有几个选择。

将表格提交给自己

<?php
    if('POST' == $_SERVER['REQUEST_METHOD']) {
        // process the form here
    }
?>
<form action="" method="POST">
    <input type="text" class="emailField" placeholder="email address" name="email" />
    <button type="submit">
        <div class="submit" />
    </button>
</form>

重定向回表格

在要显示表单的submit.php中添加类似内容。

<?php
    header('Location: http://example.org/form.php');
    exit;
?>
