[jQuery] Re: How PHP script can return two variables ?

[GreatBigBore]

Have your PHP script return an XML document:

PHP:

        /*
        <FunctionResult>
                <FunctionStatus success="1" message="Request processed" />
        </FunctionResult>
        */
        $document = DOMImplementation::createDocument();
        $document->formatOutput = true;
        $document->preserveWhitespace = true;

        $functionResult = $document->createElement('FunctionResult');
        $document->appendChild($functionResult);

        $functionStatus = $document->createElement('FunctionStatus');
        $functionResult->appendChild($functionStatus);

        $success = true;
        $message = 'Request successful';

...process the request and change $success and $message as
necessary...

        $functionStatus->setAttribute('success', $success);
        $functionStatus->setAttribute('message', addslashes($message));

        // Now respond to the requestor
        Header("Content-type: text/xml", 1);
        echo $document->saveXML();
        error_log($document->saveXML());

Javascript:

        $.post('http://' + serverName + '/ajax.php',
                {       'function' : 'getEfforts',
                        'parameter1' : something
                },

                function(xml) {
                        /*
                        <FunctionResult>
                                <FunctionStatus success="1" message="Request 
processed" />
                        </FunctionResult>
                        */
                        var statusNode = $('FunctionStatus', xml).get(0);
                        var success = 
intToBool(statusNode.getAttribute('success'));
                        if(success === true) {
                        } else {
                        }
                }
        );
