Take form data and write it to XML file

Question

I am trying to take form data (via _POST) and write it to a document using SimpleXML. This is what I have tried and I can't seem to get it to work.

<?php
$title = $_POST['title'];
$link = $_POST['link'];
$description = $_POST['description'];

$rss = new SimpleXMLElement($xmlstr);
$rss->loadfile("feed.xml");

$item = $rss->channel->addChild('item');
$item->addChild('title', $title);
$item->addChild('link', $link);
$item->addChild('description', $description);

echo $rss->asXML();

header("Location: /success.html"); 

  exit;
?>

Any help or a point in the right direction would be much appreciated.

You can't echo something and then use header().

Always post what error do you get when running the code.

You use the asXML() function wrong. If you want to write your XML to a file, you must pass a filename parameter to it. Check the SimpleXMLElement::asXML manual

so your code line oututing xml should be changed from

echo $rss->asXML();

to

$rss->asXML('myNewlyCreatedXML.xml');

rather than using SimpleXMLElement you can create XML directly like this

$xml = '<?xml version="1.0" encoding="utf-8"?>';
$xml .= '<item>';
$xml .= '<title>'.$title.'</title>';
$xml .= '<link>'.$title.'</link>';
$xml .= '<description>'.$title.'</description>';
$xml .= '</item>';
$xml_file = "feed.xml";
file_put_contents($xml_file,$xml);

may this will help you

There are a few problems with your code

<?php
$title = $_POST['title'];
$link = $_POST['link'];
$description = $_POST['description'];

//$rss = new SimpleXMLElement($xmlstr); // need to have $xmlstr defined before you construct the simpleXML
//$rss->loadfile("feed.xml");
//easier to just load the file when creating your XML object
$rss = new SimpleXML("feed.xml",null,true) // url/path, options, is_url
$item = $rss->channel->addChild('item');
$item->addChild('title', $title);
$item->addChild('link', $link);
$item->addChild('description', $description);


//header("Location: /success.html"); 
//if you want to redirect you should put a timer on it and echo afterwards but by 
//this time if something went wrong there will be output already sent, 
//so you can't send more headers, i.e. the next line will cause an error

header('refresh: 4; URL=/success.html');
echo $rss->asXML(); // you may want to output to a file, rather than the client
// $rss->asXML('outfputfile.xml');
exit;

?>

I am am getting a Parse error: syntax error, unexpected T_VARIABLE in /documentname.php on line 10 error with this. Is it because there is no semicolon on line 9? Because when I put one in I get Fatal error: Class 'SimpleXML' not found in /documentname.php on line 9
