Easy JSON with CakePHP and jQuery ...

I am not sure if this is the fanciest way to get the job done but it works REALLY well. What job am I referring to? I am referring to outputting data as JSON in a CakePHP view and then parsing it in a jQuery AJAX response. Its fairly easy to accomplish with the JSON parser provided by json.org. Scroll to the bottom and download/include json2.js.

Controller example:

01.$sizeArray = getimagesize(/path/to/really_cool_image.jpg);
02.
03.$outputArray = array(
04.    file => areally_cool_image.jpg,
05.    width => $sizeArray[0],
06.    height => $sizeArray[1],
07.);
08.
09.$this->set( aresult, $outputArray);
10.
11.$this->render(null, ajax);

AJAX View example:

1.Configure::write( wouldebug, 0);
2.echo $javascript->object($result);

jQuery AJAX response handler example:

1.function(response, status) {
2.      imageDetails = JSON.parse(response);
3.      imageName = imageDetails.file;
4.}
