PHP-使用ajax提交表单,并返回XML
我在使用jQuery/AJAX提交表单,并返回成功消息+XML文件(用PHP生成)时遇到问题 这就是我现在拥有的:PHP-使用ajax提交表单,并返回XML,php,ajax,xml,domdocument,Php,Ajax,Xml,Domdocument,我在使用jQuery/AJAX提交表单,并返回成功消息+XML文件(用PHP生成)时遇到问题 这就是我现在拥有的: invoice.php: <form method="post" id="invoiceform"> <? /* Populate the form with input later on.

echo json_encode($result);
function convertInvoice(){
/* 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("track");
$currentTrack = $xmlRoot->appendChild($currentTrack);
/* you should enclose the following two lines in a cicle */
$currentTrack->appendChild($domtree->createElement('charge','letter'));
$currentTrack->appendChild($domtree->createElement('description','Payable cover letters'));
$currentTrack->appendChild($domtree->createElement('charge','vat'));
$currentTrack->appendChild($domtree->createElement('description','Payable VAT'));
/* get the xml printed */
$xml = $domtree->saveXML();
return $xml;
}
所以,上面的页面处理返回消息。实际的XML生成函数位于下页
functions.php
:
<form method="post" id="invoiceform">
<? /* Populate the form with input later on. For now, the XML data is hardcoded in PHP */ ?>
<button type="submit">Submit form</button>
</form>
//Submit the form:
$('#invoiceform').on('submit', function(e) { //use on if jQuery 1.7+
e.preventDefault(); //prevent form from submitting
e.stopImmediatePropagation(); //prevent double.
//Show the loading message.
$form = $(this);
// Use Ajax to submit form data
$.ajax({
url: '/api/invoice/invoice_converter',
type: 'POST',
data: $form.serialize(),
dataType: "json",
success: function(data) {
console.log(data);
if (data.result == 'success') {
//Success
$(".status").html(data.message);
} else {
$(".status").html(data.message);
}
},
error: function(data) {
console.log("Something went wrong!");
console.log(data);
}
});
return false;
});
$invoice = new Invoice;
if($_POST)
{
$convertInvoice = $invoice->convertInvoice();
if($convertInvoice == 1){
$error = "Error: Error message goes here.";
$stop = true;
}
if($stop){
$result = array("result" => "error","message" => $error);
}else{
$result = array("result" => "success","message" => $convertInvoice);
}
}
header('Content-type: application/json');
echo json_encode($result);
function convertInvoice(){
/* 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("track");
$currentTrack = $xmlRoot->appendChild($currentTrack);
/* you should enclose the following two lines in a cicle */
$currentTrack->appendChild($domtree->createElement('charge','letter'));
$currentTrack->appendChild($domtree->createElement('description','Payable cover letters'));
$currentTrack->appendChild($domtree->createElement('charge','vat'));
$currentTrack->appendChild($domtree->createElement('description','Payable VAT'));
/* get the xml printed */
$xml = $domtree->saveXML();
return $xml;
}
console.log中从上面返回的数据如下:
<?xml version="1.0" encoding="UTF-8"?>
<xml>
<track>
<charge>letter</ charge >
<description>Payable cover letters</ description >
<charge>vat</ charge >
<description>Payable VAT</ description >
</track>
</xml>

这是正确的,但是,我希望能够将上述内容“保存”到XML文件中,并使其可供用户下载。您需要创建一个可写文件并将$XML写入文件。
这段代码创建track.xml,并插入下载到文档的链接 使用
fopen
以写入(如果不存在则创建)模式打开文件,然后使用fwrite
将内容写入文件,然后使用fclose
将其关闭。文件必须放在公共目录中,以确保web服务器可以访问该文件
//打开文件并写入内容
$file=fopen('track.xml','w+');
fwrite($file,$xml);
fclose($文件);
//生成下载链接
回声';
注意:您需要确保输出目录可由PHP通过以下方式写入:
chown www-data:www-data/var/www/path/to/output
chmod 775/var/www/path/to/output
您可以查看以编写以及用户下载
