我有php和xml文件的问题:我想在xml文件中添加一个元素。我写了这段代码并且有效:
<?php
$file = 'clients.xml';
$doc = new DOMDocument();
$doc->load($file);
$get_elms = $doc->getElementsByTagName("Client");
$nr_elms = $get_elms->length;
$node = $get_elms->item($nr_elms-1);
$element = $node->nodeName;
if($element=='Client') {
$idfinal=intval($node->getAttribute('id'))+1;
$client = $doc->createElement('Client');
$node->parentNode->appendChild($client);
$client->setAttribute('id',$idfinal);
$client->setAttribute('name','Any name');
$client->setAttribute('cnp','12345');
$client->setAttribute('adress','adress');
$client->setAttribute('nb','123');
$client->setAttribute('amount','1000');
$client->setAttribute('type','Any type');
}
if($doc->save('clients.xml')) {
echo htmlentities($doc->saveXML());
}
?>
如果我将完全相同的代码放入类中,则在函数addClient中它不起作用,因为它无法识别我的xml文件。我试过echo $ get_elms-&gt; length;并且它返回0并且我的变量$ element为空,因此它不会输入“if”。我需要使用这个类,因为我必须做更多的操作,如删除和更新,我必须向这些函数发送一些参数。谁能帮助我,告诉我我做错了什么?
我的班级看起来像这样:
class xmlClientMappers {
public function adaugaClient(array $row)
{
$name = $row['name'];
$adress = $row['adress'];
$cnp = $row['cnp'];
$nb = $row['nb'];
$amount = $row['amount'];
$type = $row['type'];
$file = 'clients.xml';
$doc = new DOMDocument();
$doc->load($file);
$get_elms = $doc->getElementsByTagName("*");
$nr_elms = $get_elms->length;
echo "The nomber is ".$nr_elms;
$node = $get_elms->item($nr_elms-1);
$element = $node->nodeName;
echo "<br/>Here should be the name of the last element".$element;
if($element=='Client') {
$idfinal=intval($node->getAttribute('id'))+1;
echo " id-ul e ".$idfinal;
$client = $doc->createElement('Client');
$node->parentNode->appendChild($client);
$client->setAttribute('id',$idfinal);
$client->setAttribute('name',$name);
$client->setAttribute('cnp',$cnp);
$client->setAttribute('adress',$adress);
$client->setAttribute('nb',$nb);
$client->setAttribute('amount',$amount);
$client->setAttribute('type',$type);
}
if($doc->save('clienti.xml')) {
echo htmlentities($doc->saveXML());
else echo "It is wrong!";
}
}
}
?>
谢谢!
答案 0 :(得分:0)
您必须将xml位置相对于执行请求的文件的位置。
所以例如以下结构:
lib
\ xmlClientMappers.php
\ client.xml
index.php
你必须使用&#34; ./ lib / client.xml&#34;为你的文件名。
我认为这将是问题所在。
