php form action php self

提问by Sasindu H

I have a php form like this.

我有一个这样的 php 表单。

<form name="form1" id="mainForm" method="post"enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF'];?>">

</form

In form action I want to use page name with parameters. like house.php?p_id=10111. But $_SERVER['PHP_SELF'] gives only the house.php(My page full url is house.php?p_id=10111like this) Please help me to solve this problem. thanks.

在表单操作中，我想使用带有参数的页面名称。喜欢house.php?p_id=10111。但是 $_SERVER['PHP_SELF'] 只给出了house.php（我的页面完整网址是house.php?p_id=10111这样的）请帮我解决这个问题。谢谢。

How about leaving it empty, what is wrong with that?

让它空着怎么样，那有什么问题？

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="">

</form>

Also, you can omit the action attribute and it will work as expected.

此外，您可以省略 action 属性，它会按预期工作。

You can leave action blank or use this code:

您可以将操作留空或使用以下代码：

<form name="form1" id="mainForm" method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['REQUEST_URI'];?>">
</form>

Leaving the action value blank will cause the form to post back to itself.

将操作值留空将导致表单回传给自身。

You can use an echo shortcut also instead of typing out "echo blah;" as shown below:

您也可以使用回声快捷方式而不是输入“echo blah;” 如下所示：

<form method="POST" action="<?=($_SERVER['PHP_SELF'])?>">

This is Perfect. try this one :)

太棒了。试试这个:)

<form name="test" method="post" enctype="multipart/form-data" action="<?php echo $_SERVER['PHP_SELF']; ?>">
/* Html Input Fields */
</form>

Another (and in my opinion proper) method is use the __FILE__constant if you don't like to rely on $_SERVERvariables.

__FILE__如果您不喜欢依赖$_SERVER变量，另一种（在我看来是正确的）方法是使用常量。

$parts = explode(DIRECTORY_SEPARATOR, __FILE__);
$fileName = end($parts);
echo $fileName;

About magic and predefined constants: 1, 2.

关于魔法和预定义常量：1, 2。

If you want to be secure use this:<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

如果你想安全使用这个：<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">
