Grabbing hidden inputs as a string (Using PHP Simple HTML DOM Parser)

Question

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

Answer 1

I don't use the SimpleDom (I always go whole-hog and use DOMDocument), but couldn't you do something like ->find('input[@type=hidden]')?

If the SimpleDOM doesn't allow that sort of selector, you could simply loop over the ->find('input') results and pick out the hidden ones by comparing the attributes yourself.

Answer 2

If you use DomDocument, you could do the following:

<?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);

?>
