Using colorbox(a jquery plugin) ajax in a complex situation


Colorbox is a lightweight customizable lightbox plugin for jQuery.

I am using colorbox for another perpose: to show a (semi!) modal window to show information on ajax call.

You can get the plugin here .

Here I’ll give a simple example how to load ajax data and show through colorbox plugin. In second phase i’ll try to give the scenario of the complex situation and give the solution. Though the solution looks so obvious now, i had to go through lots of other solutions (Not worthy for that situation).

Php page redirection problem


So far i did web development I used javascript redirection. But recently i needed to do that with php. But i got stacked with some annoying problems.
1. Headers are already sent.
2. SESSION variables are not setting.

1. Ok, now here javascript again rescue me see how.

function redirect($url) {
	if(!headers_sent()) {
	        //If headers not sent yet... then do php redirect
	        header('Location: '.$url);
	        exit;
	} 
	else {
	        //If headers are sent... do javascript redirect
	        echo '';
	        echo 'window.location.href="'.$url.'";';
	        echo '';
	        echo '';
	        echo '';
	        echo '';
	        exit;
	}
}

What you need to do just call this method with your desired parameter.

2.-> And now number second! SESSION variables are not setting means you are not getting SESSION variables from redirected page.
The solution is never forget to add “exit;” like a added here.

If you are stilling facing second problem, may you forgot to start session in that page!

আনাকে যা করতে হবে তা হল-

এ্কটি js function লেখা।- Continue reading
