jquery ajax not working with php simple_xml -

• how useful error messages in php? 27 answers

i'm trying update xml file via jquery ajax @ client , php simple_xml @ server.

my ajax code is:

$("input[type='radio']").click(function () {             $().progress();             $.ajax({                 type: "post",                 url: "save.php",                 data: {name: $(this).attr('name'), value: $(this).val(), id: 13618},             });     }); 

in save.php i've:

$path=""; $xmlfile=$path.'vote/'.$_post['id'].'.xml'; $xml = simplexml_load_file($xmlfile); $xml->'a'.$_post['name']=$_post['value']; $xml->asxml($path.'vote/'.$_post['id'].'.xml'); return; 

vote/13618.xml contains template of xml tags each starting 'a'.

e.g.: this fiddle, in xml file, i've:

<posts>     <a1president/>     <a2vice-president/> </posts> 

but php file not updating xml file. i'm unable track bug.

is there error in code? if yes , how fix?

you firing asxml, don't return value. if do, can check if function returns false or true.

if returns false, check further response. make sure you've enabled error reporting:

error_reporting(-1);
