如何获取PHP中提交按钮的名称?

How do I get the name of the submit button in PHP?

我知道了提交按钮的价值，但我找不到 获取按钮名称的任何代码.下面是我编写的代码.

I got the value of submit button, but I could not find any code to get the name of the button. Below is the code I have written.

<form name="form1"  method="post">
    <input type="submit" value="hello" name="submitbutton">
</form>

<?php
    echo "Value of submit button: " . $_POST['submitbutton'];
    echo "Name of submit button: " . // What should I do here? //;
?>

推荐答案

您将在$ _POST数组中找到该名称.

You will find the name in the $_POST array.

<?php
print_r($_POST);
?>

这样，您将在$ _POST数组中看到所有内容.

This way you will see everything in the $_POST array.

您可以使用以下方法遍历数组:

You can iterate through the array with:

foreach($_POST as $name => $content) { // Most people refer to $key => $value
   echo "The HTML name: $name <br>";
   echo "The content of it: $content <br>";
}
