You can add hidden fields within HTML and access them in PHP:
您可以在 HTML 中添加隐藏字段并在 PHP 中访问它们：
<input type="hidden" name="myFieldName" value="someValue"/>
Then in PHP:
然后在 PHP 中：
$val = $_POST['myFieldName'];
If you're going to ouput this again you should use htmlspecialcharsor something similar to prevent injection attacks.
如果你要再次输出它，你应该使用htmlspecialchars或类似的东西来防止注入攻击。
<input type="hidden" name="myFieldName" value="<?=htmlspecialchars($_POST['myFieldName']);?>"/>

Suppose this the form input in page A
假设这是页面 A 中的表单输入
<form name="" action="" method=post enctype="multipart/form-data">
<input type="text" name="myvalue" value="">
<input type=submit>
</form>
In page B
在 B 页
In the page you want to get values put this code
在要获取值的页面中放置此代码
<?PHP
foreach ($_REQUEST as $key => $value ) {
$$key=(stripslashes($value));
}
?>
<form name="" action="" method=post enctype="multipart/form-data">
<input type="text" name="myvalue" value="<?PHP echo $myvalue" ?>">
<input type=submit>
</form>
So yo can use or attach variable value to another form do what else you want to do
所以你可以使用或附加变量值到另一个表单做你想做的其他事情

使用以下代码，这应该对您有所帮助。
<form action ="formhandler.php" method ="POST" >
<input name = "inputfield" />
<input type="submit" />
</form>
on formhandler.php file yo need to enter following code to get the value of inputfiled.
在 formhandler.php 文件中，您需要输入以下代码以获取 inputfiled 的值。
$inputfield = isset($_POST['inputfield'])?$_POST['inputfield']:"";
// now you can do what ever you want with $inputfield value
echo($inputfield);
