AJAX and FPCGI

[Tyler]

It is easy to use fpCGI with AJAX.  I use it to send JSON formatted data
back and forth all the time.

You can either use a form already on the page, or build one on demand with
javascript.

Make sure you have all the usual fields in the form for fpCGI submission.

>From filePro, you just write out whatever you want to go back (I use JSON,
as I mentioned) and parse it on the client side.  I have a JSON javascript
class that does this for me (I could just use eval to instantiate the object
literal, but that's not very robust or secure).  (eg) instead of "*responseJson
= eval(XHTP.responseText);* " I use "*responseJson =
JSON.parse(XHTP.responseText);*".

You can grab the JSON class at http://www.json.org/json2.js if you like.

FYI, you can also use PHP to create a direct socket connection to fpCGI and
retrieve the data that way, as well.

(eg)
*            $sPost ="";
            $aPost =array();
            $aPost["Field_ddir"] ="/usr/local/apache/htdocs/";
            $aPost["Field_base"] ="ajax";
            $aPost["Field_cmd"] ="rreport someTable -fp someProcessing -sr
".rand(1,500)." -n -u -y automaticAJAX";
            $aPost["someField"] ="some data";*
*            //.....etc....*

            *foreach ($aPost as $sFieldName=>$sFieldValue) {
                if(!$bFirst) { $sPost .="&"; }
                $sPost .=urlencode($sFieldName)."=".urlencode($sFieldValue);
                $bFirst =false;
            }*
*            //you could write this all to the string directly instead of
using an array,
**            //**I just find it's clearer code to do it with an array *

            *$sHeader ="POST /cgi-bin/fpcgi HTTP/1.1\n"
                        ."Host: $yourServersIp\n"
                        ."Connection: Close\n"
                        ."Content-Type: application/x-www-form-urlencoded\n"
                        ."Content-Length: ".strlen($sPost)
                        ."\n\n$sPost\n";

            $oSocket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
            $bSuccess = socket_connect($oSocket, $yourServersIp, 80);

            $iBytesSent =socket_write ($oSocket, $sHeader);

            $sResponse = "";

            while ($c =socket_read($oSocket, 2056)) { $sResponse .=$c; }

            socket_close($oSocket);*
