【问题描述】：
首先，我为我糟糕的英语道歉，非常糟糕。
我今天来找你，试图为我的问题找到解决方案。我解释一下：
对于我的学校项目，我需要对我公司的 PC 进行盘点，并将其与客户的工作表相关联。为此，我有两个数据库，一个用于库存，另一个用于客户信息（名字、姓氏和他的公司名称）。
所以数据库上的连接很好，但是我在从 XML 文件中的两个数据库导出数据时遇到了一些麻烦。目前我在 PHP 和其他互联网语言方面的表现非常糟糕，因为除了现在我的项目之外，我从未练习过它。
所以代码是：
<?php
include 'connection.php';
$client = $_POST['MagicCash'];
$pc = $_POST['fusioninventory'];
$nom = $bdd->query("SELECT nom FROM client WHERE IDClient= '.$client.'");
$prenom = $bdd->query("SELECT prenom FROM client WHERE IDClient= '.$client.'");
$societe= $bdd->query("SELECT societe FROM client WHERE IDClient='.$client.");
$CPU = $bdd->query("SELECT designation FROM glpi_deviceprocessors WHERE id= '.$pc.'");
$Archs = $bdd->query("SELECT name FROM glpi_plugin_fusioninventory_computerarchs WHERE id= '.$pc.'");
$DD = $bdd ->query("SELECT name, totalsize, freesize FROM glpi_computerdisks WHERE id= '.$pc.'");
$model = $bdd ->query("SELECT name FROM glpi_computermodels WHERE id= '.$pc.'");
$licence = $bdd->query("SELECT os_license_number, os_licenseid FROM glpi_computers WHERE id='.$pc.'");
$GPU = $bdd ->query("SELECT designation FROM glpi_devicegraphiccards WHERE id='.$pc.'");
$DD2 = $bdd ->query("SELECT designation FROM glpi_deviceharddrives WHERE id='.$pc.'");
$RAM = $bdd->query("SELECT designation, frequence FROM glpi_devicememories WHERE id='.$pc.'");
$OS = $bdd->query("SELECT name FROM glpi_operatingsystems WHERE id='.$pc.'");
$SP = $bdd->query("SELECT name FROM glpi_operatingsystemservicepacks WHERE id='.$pc.'");
/* create a dom document with encoding utf8 */
$domtree = new DOMDocument('1.0', 'UTF-8');
/* create the root element of the xml tree */
$xmlRoot = $domtree->createElement("xml");
/* append it to the document created */
$xmlRoot = $domtree->appendChild($xmlRoot);
$currentTrack = $domtree->createElement("inventaire");
$currentTrack = $xmlRoot->appendChild($currentTrack);
/* you should enclose the following two lines in a cicle */
$currentTrack->appendChild($domtree->createElement('nom',$nom));
$currentTrack->appendChild($domtree->createElement('prenom',$prenom));
$currentTrack->appendChild($domtree->createElement('societe',$societe));
$currentTrack->appendChild($domtree->createElement('designation',$CPU));
$currentTrack->appendChild($domtree->createElement('name',$Archs));
$currentTrack->appendChild($domtree->createElement('name, totalsize, freesize',$DD));
$currentTrack->appendChild($domtree->createElement('name',$model));
$currentTrack->appendChild($domtree->createElement('os_license_number, os_licenseid',$licence));
$currentTrack->appendChild($domtree->createElement('designation',$GPU));
$currentTrack->appendChild($domtree->createElement('designation',$DD2));
$currentTrack->appendChild($domtree->createElement('designation',$RAM));
$currentTrack->appendChild($domtree->createElement('name',$OS));
$currentTrack->appendChild($domtree->createElement('name',$SP));
/* get the xml printed */
echo $domtree->saveXML();
?>
我有这个错误：
Warning: DOMDocument::createElement() expects parameter 2 to be string, object given in C:\xampp\htdocs\xmlv3.php on line 34
Catchable fatal error: Argument 1 passed to DOMNode::appendChild() must be an instance of DOMNode, null given in C:\xampp\htdocs\xmlv3.php on line 34
我让你我的 HTML 代码：
include 'connection.php';
echo"<br>";
?>
<!DOCTYPE html>
<html lang="en-AU" class="subpage">

<meta charset="utf-8" />
<script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.11.3.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<title>Projet</title>
</head>
<body>
<form action="xmlv3.php" method="post">
<label for="MagicCash">Client :</label>
<select name="MagicCash" id="mc">
<?php
$id = array();
global $bdd;
$rep = $bdd->query("SELECT * FROM client ORDER BY 'IDClient' DESC");
while ($tab = $rep->fetch()){
echo '<option name="client" value="'.$tab['IDClient'].'">'.$tab['IDClient'].' - '.$tab['Nom'].' '.$tab['Prenom'].'</option>';
}
?>
</select>
<label for="fusioninventory">PC :</label>
<select name="fusioninventory" id="fi">
<?php
$id = array();
global $bdd1;
$rep = $bdd1->query("SELECT id,designation,frequence FROM glpi_deviceprocessors ORDER BY 'id' DESC");
while ($tab1 = $rep->fetch()){
echo '<option name="pc" value="'.$tab1['id'].'">'.$tab1['id'].' - '.$tab1['designation'].' '.$tab1['frequence'].'</option>';
}
?>
</select>
<input type="submit" value="Valider">
</form>
</body>
感谢您在未来的帮助。
