Trying to make a simple XML that takes the data registered in a PHP page but is giving error, someone can tell me what it is and how it can work?

Error that appears when pressing the button:

Fatal error: Uncaught Exception 'Domexception' with message 'Hierarchy Request Error' in C: xampp... cadastro.php:17 Stack trace: #0 C: xampp... cadastro.php(17): Domnode->appendchild(Object(Domelement)) #1 {main} thrown in C: xampp... cadastro.php on line 17

Full page code:

<?php 

if (isset($_POST['insert'])){

$xml= new DOMDocument("1.0", "UTF-8");
$xml->load('studentdb.xml');

$nome = $_POST['nome'];
$endereco = $_POST['endereco'];

$rootTag = $xml->getElementsByTagName("roo")->item(0);

$infoTag = $xml->createElement("info");
    $nomeTag = $xml->createElement("nome", $nome);
    $enderecoTag = $xml->createElement("endereco", $endereco);

    $nomeTag->appendChild($nomeTag);
    $enderecoTag->appendChild($enderecoTag);

$rootTag->appendChild($infoTag);
$xml->save('studentdb.xml');

}
?>

<html>

<form method="post" action="cadastro.php">

This error is because you are trying to move a Node inside yourself.

Here you go an explanation of a question like yours.

I hope I’ve helped.

UPDATING:

Take a look at line 17 and 18 of your code. I believe that’s the problem.

$nomeTag->appendChild($nomeTag);
$enderecoTag->appendChild($enderecoTag);

  • Bludgeoned, I was frightened by the post photo kkkkk.

  • kkkkkkkkkkkk tb I found a lot loco, but there’s no way I can’t help looking at her kkkkkkkkkkkkkkkk

  • until I understood what is happening, I just didn’t understand very well how to fix :/

  • I edited the answer, I believe it’s a problem on line 17 E18
