        <FullName></FullName>
        <Company></Company>
        <Degree_Certificate></Degree_Certificate>
        <City></City>
        <StateProvidenceRegion></StateProvidenceRegion>
        <Phone></Phone>
        <Emailaddress></Emailaddress>
        <Descriptions></Descriptions>
    </affiliate>

<affiliates>

PHP code: problems:

$root = $doc->createElement('affiliate', '');
$aff = count($root);
for ($i = 0; $i < $aff; $i++)
{
    $root->setAttribute('id', $i);
    $fullname = $doc->createElement('FullName', $fname.' '.$lname);
    $certdegree = $doc->createElement('Degree_Certificate', $degree);
    $Company = $doc->createElement('Company', $company);
    $Street = $doc->createElement('City', $address);
    $StateProvidenceRegion = $doc->createElement('StateProvidenceRegion', $state);
    $Phone = $doc->createElement('Phone', $phone);
    $EmailAddress = $doc->createElement('Emailaddress', $email);
    $Description = $doc->createElement('Descriptions', $message);
    $doc->appendChild($root);
    $root->appendChild($fullname);
    $root->appendChild($Company);
    $root->appendChild($certdegree);
    $root->appendChild($Street);
    $root->appendChild($StateProvidenceRegion);
    $root->appendChild($Phone);
    $root->appendChild($EmailAddress);
    $root->appendChild($Description);
    $doc->documentElement->appendChild($root);
}

Help me please with this code. PHP is not my strong point. What piece of code did I not add.

Answer 1

<?php
//Process form data here.

//Get the XML Document
$doc = new DOMDocument();
$doc->load("affiliates.xml"); //Load the existing XML here.

//Get the affiliates node here
$root = $doc->documentElement;

//Get the ID of this record here.
//If you know that no affiliate entries will ever be deleted, then you can use the total number of entries as the next increment value.
$totalAffiliates = $root->childNodes->length;

$node = $doc->createElement("affiliate");
$node->setAttribute("id", $totalAffiliates);
$node->appendChild($doc->createElement("FullName", $fname . ' ' . $lname));
$node->appendChild($doc->createElement("Degree_Certificate", $degree));
$node->appendChild($doc->createElement("Company", $company));
$node->appendChild($doc->createElement("City", $address));
$node->appendChild($doc->createElement("StateProvidenceRegion", $state));
$node->appendChild($doc->createElement("Phone", $phone));
$node->appendChild($doc->createElement("Emailaddress", $email));
$node->appendChild($doc->createElement("Descriptions", $message));

$root->appendChild($node);

//Write your XML back to the file.
?>

This code should give you what you need. You will need to adjust it in a few places, to fit what you already have.
