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

[GreatBigBore]

Have your PHP script return an XML document, and then parse that XML
with JQuery:

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';

...Do stuff that changes $success and $message if necesssary...

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

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

Javascript:

$.post('http://myserver.com/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 {
                }
        }
);
