JSON and Zend Framework? – Zend_Json

micro tutorial, PHP, zend framework, , , , , , , , , , , ,

That’s really a good Zend Framework’s class that help you do the encode/decode job very easily. First of all it escapes everything for you and second it prints a correct/valid code. Note that sometimes if you have a trailing whitespace after the closing PHP tag – ?> that will result in an error.

Here’s some code:

public function jsonAction()
{
	$data = array(3,4,'test', 'my-name' => 3,4);
 
	echo Zend_Json::encode($data);
 
	$this->_helper->viewRenderer->setNoRender(true);
	$this->view->layout()->disableLayout();
}

and the result is:

{"0":3,"1":4,"2":"test","my-name":3,"3":4}

Note that all integers are printed without double quotes – which saves some space!

Flowplayer and Captions (Subtitles)

javascript, web development, , , , ,

Actually I couldn’t mange to make it work with a non-javascript approach, but however with the .js help it works. I’ll paste here this code, hopefully this will help.

Note that you’ve to change plugins/javascripts/videos/captions path!

<html>
<body>
<div id="player" style="width:480px;height:360px"></div>
<script src="Flowplayer.Captions/flowplayer-3.2.2.min.js"></script>
<script>
 
$f("player", "Flowplayer.Captions/flowplayer-3.1.5.swf", {
    clip : {
        url : "Flowplayer.Captions/bach.flv",
        captionUrl : 'Flowplayer.Captions/bachen.srt'
    },
    plugins:  {
        captions: {
            url: 'Flowplayer.Captions/flowplayer.captions-3.2.1.swf',
            captionTarget: 'content'
        },
        content: {
            url : 'Flowplayer.Captions/flowplayer.content-3.2.0.swf',
            bottom: 5,
            height: 50,
            backgroundColor: 'transparent',
            backgroundGradient: 'none',
            border: 0,
            textDecoration: 'outline',
            style: {
                body: {
                    fontSize: 15,
                    fontFamily: 'Arial',
                    textAlign: 'center',
                    color: '#ffffff'
                }
            }
        },
        controls: {
            url : 'Flowplayer.Captions/flowplayer.controls-3.1.5.swf'
        }
    }
});
 
setTimeout(function() {
    $f('player').getPlugin('captions').loadCaptions(0, 'Flowplayer.Captions/bachbg.srt');
}, 3000);
 
</script>
</body>
</html>

Detecting Pressed Key with e.which in JavaScript

javascript, , , , , , ,

You have definitely decided to get which key has been pressed with JavaScript? This is very common when it comes to an Enter key press over a form element. Actually this should be automatically done by the browser, but when it comes to a default prevented form you’ve to check it for yourself.

The job can be done with a event’s which check. Let me show you some JavaScript/jQuery code:

$('.selector').click(function(e) {
	console.log(e.which);	
});

Note that this can be checked under Firefox and/or Safari like browsers which support the console object. This will give you the idea which key is pressed in a number value. The Enter is usually 13!
If you don’t have such browser, you can replace that code with something like:

$('.selector').click(function(e) {
	alert(e.which);	
});

PHP: Conditionals Coding Style

PHP, , , , , , , ,

Just to continue with PHP coding style, let me suggest a conditional statement coding standard. Just don’t use large three operands conditions like that:

condition ? if_true : if_false

If it’s too long it will be difficult to read and maintain. Better is:

(condition)
	? (if_true)
	: (if_false);

PHP Coding Style: Large IF Statements

micro tutorial, PHP, , , , , , , ,

Have you ever seen some PHP code like that:

1
2
3

if ($condition1 && $condition2 && $string1 == $string2 . $string3 && $string4 != $string5 . $string6) {
   // write some code here!?
}

It is ugly, isn’t it?

I’d prefer to make it clearer! What about that?

1

if ($condition1 
   && $condition2
   && $string1 == $string2
                . $string3
   && $string4 != $string5
                . $string6
) {
   // write some code here
}
