$book = array(

    'btitle' => $_POST['btitle'],
    'bdate' => $_POST['bdate'],
    'bookrentdate' => $_POST['bookrentdate'],
    'booksid' => $_POST['booksid'],   
);
 
echo $book["bid"];
$doc = new DOMDocument();
$doc->load( 'loaned.xml' );


$booklist = $doc->getElementsByTagName( "book" );
foreach( $booklist as $book1 )
{
  $bookids = $book1->getElementsByTagName( "ID" );
  $bookid = $bookids->item(0)->nodeValue;  
}
echo "<b>$bookid<br>";
$bookid=$bookid+1;
$book["bid"] = $bookid;
echo "<b>$bookid<br>";


$doc->formatOutput = true;
$r = $doc->getElementsByTagName("resource")->item(0);

$b = $doc->createElement("book");

$bid = $doc->createElement("ID");
$bid->appendChild(
    $doc->createTextNode( $book["bid"] )
);
$b->appendChild( $bid );

$btitle = $doc->createElement("title");
$btitle->appendChild(
    $doc->createTextNode( $book["btitle"] )
);
$b->appendChild( $btitle );


$bdate = $doc->createElement("date");
$bdate->appendChild(
    $doc->createTextNode( $book["bdate"] )
);

$b->appendChild( $bdate );

$bookrentdate = $doc->createElement("retdate");
$bookrentdate->appendChild(
    $doc->createTextNode( $book["bookrentdate"] )
);
$b->appendChild( $bookrentdate );

$booksid = $doc->createElement("SID");
$booksid->appendChild(
    $doc->createTextNode( $book["booksid"] )
);

$b->appendChild( $booksid );
$r->appendChild( $b );
   
$doc->save("loaned.xml");

header("Location: {$_SERVER['HTTP_REFERER']}");
