Question

我有一个XML文件，我希望能够使用表单进行编辑。

student.xml

<students>
  <student>
    <name>Jane Doe</name>
    <email>email@email.com</email>
    <school>School Name</school>
    <coach>Coach Name</coach>
  </student>
</students>

基本上我的表单设置如下：

<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代码：

<?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');

?>

如何使用表单在一个表单中编辑多个节点？现在它将所有节点更改为与第一个节点相同。

编辑：代码已更新。这一切似乎都在起作用。谢谢你的帮助。

Answer 1

以下对我有用。

旁注： 但是，我不确定您为何使用$data->student->coach=$_POST['coach'];代替$data->item->coach=$_POST['coach'];

（另请参阅脚注） - 重要。

<?php

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

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

 $data->item->name=$_POST['name'];

 $data->item->school=$_POST['school'];

 $data->item->coach=$_POST['coach'];


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

$data=simplexml_load_file('student.xml');
$welcome=$data->item->name;
$school=$data->item->school;
$coach=$data->item->coach;

?>

<?php

echo $welcome . " ";
echo $school . " ";
echo $coach . " ";

?>

<form method="post">

Coach name: <br>
<input type = "text" name = "coach"> Present value in file: <?php echo $coach; ?>
<br><br>

School name: <br>
<input type = "text" name = "school"> Present value in file: <?php echo $school; ?>
<br><br>
Name: 
<br>
    <textarea name = "name"><?php echo $welcome; ?></textarea>
    <br>
    <input type="submit" name="submit" value="submit">
</form>

生成（在使用不同的值编辑后）：

<?xml version="1.0"?>
<welcome>
    <item>
        <name>name 1</name>
    <school>St-Peter</school>
<coach>Robert</coach>
</item>
</welcome>

使用生成的不同值进行编辑：

<?xml version="1.0"?>
<welcome>
    <item>
        <name>name 2</name>
    <school>St-Andrews</school>
<coach>George</coach>
</item>
</welcome>

<强>脚注：

为了使其正常工作，必须已存在具有以下结构的现有文件。

<welcome>
    <item>
        <name>A name</name>
    <school>A school name</school>
<coach>A coach's name</coach>
</item>
</welcome>

Answer 2

我注意到您正在使用<form action= method="post">。必须更改为：

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

另外，如果要链接到文件，则必须类似于<form action="afile.html" method="post">。
