使用JavaScript将PHP中的可下载文件返回到Internet Explorer

Question

I have a PHP web application in which users can click a button to download an XML file generated on the fly. It has worked well for a long time, but suddenly I am getting bug reports from a single Internet Explorer user (I only have a screenshot showing the bug). I need your help to figure out possible causes.

First, the button click in the web GUI is handled with jQuery which has a JavaScript window.location statement:

$("#generate-button").click(function() {
    ...
    window.location = "generateXml.phtml";
}

generateXml.phtml is PHP which creates an XML string which is returned:

header('Content-Type: application/xml');
header('Content-Disposition: attachment; filename=xmlFile.xml');
echo $xmlString;

Up until now, users have always been prompted whether to open or save the xmlFile.xml (which is correct). Now however, a user of Internet Explorer (version unknown but it appears to be IE10) is prompted whether to open or save generateXml_phtml :

Note that IE has replaced the . (dot) with _ (underscore). It seems the PHP server code in generateXml.phtml is not even executed.

Do you have any ideas? I cannot replicate the bug using IE on my own system.

Answer 1

Can you give a direct link to the problem? Try change the extenssion to .php its weird if the file ins´t being processed the web server should only give you a executed code not the raw code, maybe is something wrong with .phtml extenssion...
