提交表单给self - submit form to self

submit form to self

本文关键字：self 表单提交 | 更新日期: 2023-09-27

目前，我有一个带有输入(文本)和提交表单的按钮的表单。

表单被提交到'submit.php'。我想把表单张贴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!");
    }
?>

我想你有几个选择。

将表单提交到自身

<?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>

重定向回表单

在submit.php中添加这样的内容，您想要显示表单。

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