So I have a form that has 4 inputs, 2 text, 2 hidden. I've grabbed the two text input values from the name, which are (get_me_two, get_me_three) and I've also grabbed the form action which is (get_me.php). What I'm looking to do now is grab the 2 hidden inputs, but not the values. I want to grab the inputs themselves.

E.G: Here's my form:

<form action="get_me.php" method="post">
    <input type="text" name="get_me_two">
    <input type="text" name="get_me_three">
    <input type="hidden" name="meta_required" value="from">
    <input type="hidden" name="meta_forward_vars" value="0">
</form>

And what I want to grab from here is the two hidden inputs, Not the values, the complete string.

I'm not sure how to grab these using: PHP Simple HTML DOM Parser, if anybody knows a way that would be great, if not, if there's an alternative that also would be great. Once I've grabbed these I plan on passing the 2 input values to another page with the hidden strings, and of course the form action.

Also, if anybody is interested here's my full code, which includes the simple html dom functionality. 

<?php

include("simple_html_dom.php");

// Create DOM from URL or file
$html = file_get_html('form_show.php');
$html->load('
<form action="get_me.php" method="post">
<input type="text" name="get_me_two">
<input type="text" name="get_me_three">
<input type="hidden" name="meta_required" value="from">
<input type="hidden" name="meta_forward_vars" value="0">
</form>');

// Get the form action
foreach($html->find('form') as $element) 
   echo $element->action . '<br>';

// Get the input name       
foreach($html->find('input') as $element) 
   echo $element->name . '<br>';
?>

So, the end result would grab the 3 values, and then the 2 hidden inputs (full strings). Help would be much appreciated as It's driving me a little mad trying to get this done.

我不使用 SimpleDom（我总是全力以赴并使用 DOMDocument），但你不能做类似的事情->find('input[@type=hidden]')吗？

如果 SimpleDOM 不允许这种选择器，您可以简单地循环->find('input')结果并通过自己比较属性来挑选隐藏的结果。

如果您使用DomDocument，您可以执行以下操作：

<?php
    $hidden_inputs = array();
    $dom = new DOMDocument('1.0');
    @$dom->loadHTMLFile('form_show.php');

    // 1. get all inputs
    $nodes = $dom->getElementsByTagName('input');

    // 2. loop through elements
    foreach($nodes as $node) {
        if($node->hasAttributes()) {
            foreach($node->attributes as $attribute) {
                if($attribute->nodeName == 'type' && $attribute->nodeValue == 'hidden') {
                    $hidden_inputs[] = $node;
                }
            }
        }
    } unset($node);

    // 3. loop through hidden inputs and print HTML
    foreach($hidden_inputs as $node) {
        echo "<pre>" . htmlspecialchars($dom->saveHTML($node)) . "</pre>";
    } unset($node);

?>
