[SOLVED] Appending xml using simplexml

[pauljr8]

How do I add to the contents of gbook.xml? Tried everything I can think of :-(

 

gbook.xml

<guestbook>

<entry date" ">

<name></name>

<email></email>

<homepage></homepage>

<country></country>

<comment></comment>

</entry></guestbook>

 

<?php

if (file_exists('gbook.xml')) {

    $xml = simplexml_load_file('gbook.xml');

 

} else {

    exit('Failed to open gbook.xml.');

}

$entry=$xml->addChild('entry');

$entry->addAttribute('date',date("r"));

$entry->addChild('name',$_POST["name"]);

$entry->addChild('email',$_POST["email"]);

$entry->addChild('homepage',$_POST["homepage"]);

$entry->addChild('country',$_POST["country"]);

$entry->addChild('comment',$_POST["comment"]);

$result=file_put_contents("gbook.xml",$entry->asXML()); if ($result<1 or

result==false): echo 'error writing: '.$result; endif;

?>

 

When using:

$entry=$xml->guestbook->addChild('entry');

gbook.xml is blanked. Using it as written, it replaces all other entries

including the root element with the new entry so the next time an entry is

attempted, it fails.

 

Apache/2.2.3 (Unix) PHP/5.2.3

You'd need a mix of DOM and simplexml

 

<?php

$xml = new domDocument;

$gb = $xml->createElement('guestbook');
$xml->appendChild($gb);
  
$entry=$xml->createElement('entry');
$gb->appendChild($entry);

$entry->setAttribute('date', date('r'));

$child = $xml->createElement('name','barand');
$entry->appendChild($child);

$child = $xml->createElement('email','barand@xxx.com');
$entry->appendChild($child);

$sxml = simplexml_import_dom($xml);
echo $sxml->asXML(); 

?>

Many thanks for your reply. The problem was 2 fold, I wanted to avoid using the dom if possible. Reading the php manual on simplexml caused me to think it was possible, hmmmm.

 

Secondly, the gbook.xml already exists with data and the goal is to add new entry[date]/name/email/ etc. to the existing file, after receiving the data from a form post.

try

<?php
if (isset($_POST['sub']))
{
    $xml = new domDocument;
    $xml->load('gbook.xml');

    $gblist = $xml->getElementsByTagname('guestbook');
    $gb = $gblist->item(0);
      
    $entry=$xml->createElement('entry');
    $gb->appendChild($entry);

    $entry->setAttribute('date', date('r'));

    $child = $xml->createElement('name',$_POST['name']);
    $entry->appendChild($child);

    $child = $xml->createElement('email',$_POST['email']);
    $entry->appendChild($child);

    $xml->save('gbook.xml');
}
?>
<form method='post'>
Name <input type="text" name="name"><br>
Email <input type="text" name="email"><br>
<input type="submit" name="sub" value="Add">
</form>

Thanks again for all your help. Of course there's not much (any) simplexml in the solution. Maybe it's just useful when creating web pages with php. I use XSLT to transform and display  the xml data.

 

Thanks again.
