使用PHP表单编辑XML文件

Question

I have an XML file that I want to be able to edit using a form.

student.xml

<students>
  <student>
    <name>Jane Doe</name>
    <email>[e-mail]</email>
    <school>School Name</school>
    <coach>Coach Name</coach>
  </student>
</students>

Basically my form is set up like this:

<form method="post">
  <input name="name" id="name" type="text">
  <input name="school" id="school" type="text">
  <input name="coach" id="coach" type="text">
  <br>
  <input type="submit" name="submit" value="submit">
</form>

PHP code:

<?php
if(isset($_POST['submit'])) {
$data=simplexml_load_file('student.xml');

$data->student->name=$_POST['name'];
$data->student->school=$_POST['school'];
$data->student->coach=$_POST['coach'];

$handle=fopen("student.xml","wb");
fwrite($handle,$data->asXML());
fclose($handle);
}

$data=simplexml_load_file('student.xml');

?>

How can I use a form to edit multiple nodes in one form? Right now it changes all the nodes to the same as the first one.

Edit: Code is updated. It all seems to be working now. Thanks for the help.

Answer 1

I have noticed that you are using <form action= method="post">. It must be changed to:

<form action="" method="post">

Also, if you want to link to a file, it must be like <form action="afile.html" method="post">.
