I am attempting to make an addressbook using a php form/validation which then generates an xml file. I have every part of it working, validation/confirmation/xml generation but I am running into some problems with data not saving (it is erasing the previous xml instead of appending it). I am really new at this so I will apologize if my code is messy. Once I get this solved I am also hoping to use xsl to transform the xml into a nice table but I have problems with that not reading as well... Here is my code around the forms:
<?php
// define configuration file name and path
$configFile = 'abook.xml';
// if form not yet submitted
// display form
if (!isset($_POST['submit'])) {
// set up array with default parameters
$data = array();
$data['name'] = null;
$data['email'] = null;
$data['caddress'] = null;
$data['city'] = null;
$data['state'] = null;
$data['zipcode'] = null;
$data['phone'] = null;
$data['pug'] = null;
$data['comment'] = null;
$data['subscribe'] = null;
// read current configuration values
// use them to pre-fill the form
if (file_exists($configFile)) {
$doc = new DOMDocument();
$doc->preserveWhiteSpace = false;
$doc->load($configFile);
$address = $doc->getElementsByTagName('address');
foreach ($address->item(0)->childNodes as $node) {
$data[$node->nodeName] = $node->nodeValue;
}
}
?>
and then at the end after the form has been submitted:
/snips out the validation code/
// generate new XML document
$doc = new DOMDocument();
// create and attach root element <configuration>
$root = $doc->createElement('addressbook');
$configuration = $doc->appendChild($root);
// create and attach <oven> element under <configuration>
$address = $doc->createElement('address');
$configuration->appendChild($address);
// write each configuration value to the file
foreach ($config as $key => $value) {
if (trim($value) != '') {
$elem = $doc->createElement($key);
$text = $doc->createTextNode($value);
$address->appendChild($elem);
$elem->appendChild($text);
}
}
// format XML output
// save XML file
$doc->formatOutput = true;
$doc->save($configFile) or die('ERROR: Cannot write configuration file');
echo 'Thank you for filling out an application.';
}
?>
Is there a way to get this to not create new xmls and just add to the existing one? Once I get some input on that I'll go into my xsl problem but I think part of it has to do with a new xml being created likely wipes out my link to the style sheet....
