AJAX: posting a ampersand?

[Kevin Cornwell]

I can't seem to post a '&' in a post from via AJAX. Everything else works fine.

in my form..
oFrm.my_shout.value = 'foo & bar';

AJAX...

var sPostData = "status=add&viewing=global&cururl=" + oFrm.cururl.value + "&Color=" + oFrm.Color.options[oFrm.Color.selectedIndex].value + "&my_shout=" + encodeURI(oFrm.my_shout.value) + "&add_shout=Shout";
var url = ipb_var_base_url + "act=module&module=ajax_sb&cmd=add_shout";
oFrm.my_shout.value = '';
ajaxThis(url, parseAJAX_post_global_shout, true, true, sPostData);
 

 
function ajaxThis(url, callBackFunction, async, bPreventServerCaching, sPostData){
    bOpenXMLHTTP = true;
    //prevent browser caching by sending always sending a unique url.
    if (bPreventServerCaching){url = url + "&NoCache=" + Math.floor(Math.random()*10000);}
    //alert(url);
    var req = newXMLHttpRequest();    // Obtain an XMLHttpRequest instance
    var handlerFunction = getReadyStateHandler(req, callBackFunction);    // Set the handler function to receive callback notifications from the request object
    req.onreadystatechange = handlerFunction;
if (sPostData){
req.open('POST', url, async);  // Third parameter specifies request is asynchronous.
req.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
req.setRequestHeader("Content-length", sPostData.length);
req.setRequestHeader("Connection", "close");
req.send(sPostData);
} else {
req.open('GET', url, async);  // Third parameter specifies request is asynchronous.
    req.send(null);
}
}
 
...

in my php...

print $_POST['my_shout'];  

returns...
foo

You need to escape/encode it.

Just look at Google for JavaScript encodeURI or JavaScript escape

Note that this is not something that is Ajax specific -- when formatting a URL by hand you must encode parameter values.

Works! Thanks Eric.
