In index.php add the following form for inserting new data in xml using php


<form action="booklistaction.php" method="post">
 <table>
   <tr> 
     <td colspan="2"class="labelcell"><label for="btitle">Book Title:</label></td>
     <td colspan="2"class="fieldcell"><input type="text" id="btitle" name="btitle"  tabindex="1"/></td>
   </tr>
      <tr> 
     <td colspan="2"class="labelcell"><label for="bdate">Book Issue date:</label></td>
     <td colspan="2"class="fieldcell"> <input type="text" id="bdate" name="bdate"  tabindex="2"/><br />

Then create booklistaction.php and add the following code in this file:


<?php
$book = array(
    'bid' => $_POST['bid'],
    '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']}");   
?>
</body>

Leap Year Calculator

We know any year that is evenly divisible by 4 is a leap year : for example, 1988, 1992, and 1996 are leap years.  However, there is still a small error that must be accounted for. To eliminate this error, the Gregorian calendar stipulates that a year that is evenly divisible by 100 (for example, 1900) is a leap year only if it is also evenly divisible by 400.  For this reason, the following years are not leap years: 1700, 1800, 1900, 2100, 2200, 2300, 2500, 2600 This is because they are evenly divisible by 100 but not by 400.  The following years are leap years: 1600, 2000, 2400 This is because they are evenly divisible by both 100 and 400.  How to determine whether a year is a leap year To determine whether a year is a leap year, follow these steps: If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5. If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4. If the year is evenly divisible by 400, go to step 4. Ot
