How to get the NodeValue from <td> type input
Question
I am using this HTML and I am trying to parse it to get the nodeValue of all the elements in the table columns.
<table id="custinfo">
<tr>
<td><label>First Name</label></td>
<td><input type="text" name="firstname" ></td>
</tr>
<tr>
<td><label>Last Name</label></td>
<td><input type="text" name="lastname" ></td>
</tr>
<tr>
<td><label>Phone Number</label></td>
<td><input type="text" name="email" ></td>
</tr>
</table>
Here is the PHP It's only working for the labels but not for the input types.
$Dom= new DOMDocument();
libxml_use_internal_errors(true);
$Dom->loadHTMLFile('Pre_order.html');
$info=$Dom->getElementById('custinfo');
$inforows=$info->getElementsByTagName("tr");
$input_tags = $Dom->getElementsByTagName('input');
$fnamecol=$inforows->item(0)->getElementsByTagName("td");
$fname=$fnamecol->item(1)->nodeValue; //this is returning null Instead of returning the input text value.

Use simple_dom_parser.php library instead (Download library: https://sourceforge.net/projects/simplehtmldom/files/ & docs: http://simplehtmldom.sourceforge.net/ )
require_once('simple_dom_parser.php');
// Create DOM from file
$html = file_get_html('Pre_order.html');
// Find all labels
foreach($html->find('label') as $label)
echo $label->plaintext . '<br>';
// Find all inputs
foreach($html->find('input') as $input)
echo $input->name . '<br>';

After actually adding values to the input elements, try the following
$input_tags->item(1)->getAttribute('value')
(Btw, check the case of $Dom and $dom in your examples.)
Here's some sample code that works when executed at http://sandbox.onlinephpfunctions.com/ :
<?php
$htmlString = <<<HTML
<table id="custinfo">
<tr>
<td><label>First Name</label></td>
<td><input type="text" name="firstname" value="Jane"></td>
</tr>
<tr>
<td><label>Last Name</label></td>
<td><input type="text" name="lastname" value="Doe"></td>
</tr>
<tr>
<td><label>Phone Number</label></td>
<td><input type="text" name="email" value="212-555-1212"></td>
</tr>
</table>
HTML;
$dom= new DOMDocument();
$dom->loadHTML($htmlString);
$input_tags = $dom->getElementsByTagName('input');
echo $input_tags->item(1)->getAttribute('value'); // "Doe"
