如何制作一个提交给自己的 PHP 表单? [英] How do I make a PHP form that submits to self?
问题描述
如何制作一个自我发布/自我提交的表单,即一个将结果提交给自己的表单,而不是提交给另一个表单?
How do I make a self-posting/self-submitting form, i.e. a form that submits the results to itself, instead of submitting to another form?
推荐答案
正确的方法是使用 $_SERVER["PHP_SELF"]
(结合 htmlspecialchars
以避免可能的漏洞).您也可以跳过 action=
部分为空,这不是 W3C 有效的,但目前适用于大多数(所有?)浏览器 - 如果为空,默认是提交给 self.
The proper way would be to use $_SERVER["PHP_SELF"]
(in conjunction with htmlspecialchars
to avoid possible exploits). You can also just skip the action=
part empty, which is not W3C valid, but currently works in most (all?) browsers - the default is to submit to self if it's empty.
这是一个示例表单,它采用姓名和电子邮件,然后显示您在提交时输入的值:
Here is an example form that takes a name and email, and then displays the values you have entered upon submit:
<?php if (!empty($_POST)): ?>
Welcome, <?php echo htmlspecialchars($_POST["name"]); ?>!<br>
Your email is <?php echo htmlspecialchars($_POST["email"]); ?>.<br>
<?php else: ?>
<form action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]); ?>" method="post">
Name: <input type="text" name="name"><br>
Email: <input type="text" name="email"><br>
<input type="submit">
</form>
<?php endif; ?>
