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

by

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).

Insert line breaks into a long string to fit a length : Minimizing the risk of cutting a word unexpectedly

by 

import java.util.Calendar;
import java.util.Date;
 
 
public class test {
  public static void main(String[] argv) {
	  String s = "Here, startIndex specifies the beginning index, and endIndex specifies the stopping point. The string returned contains all the characters from the beginning index, up to, but not including, the ending index. The following program uses substring( ) to replace all instances of one substring with another within a string:";// used to insert any string or character at the specified position in the given string."; 	  
      int charsPerLine = 10;
      System.out.println(insertLinebreaks(s, charsPerLine));	     
  }
  
  public static String insertLinebreaks(String s, int charsPerLine){	  
      String[] tokens = s.split(" ");
      String temp="";
      String retS = "";
      int maxRightPadding = 5; // Increasing the value'll minimize the risk of cutting a word unexpectedly, but woun't give good performance to break continuous string(without space/br). 
	  
      for (int i=0; i charsPerLine){
	      if((charsPerLine - temp.length()) <= maxRightPadding){
		  retS = retS+temp+ "\n";

jQuery Ajax Tooltip

by

This is very much based on the Coda Popup Bubble example for jQuery that’s been going around with a few important differences:

  1. The information is requested via AJAX, so you don’t have to include all of this extra information in a hidden div. This keeps your markup smaller for grids with tons of names in it.
  2. When you mouse over another name, the previous one will disappear. If you tried this with the original Coda example, you’d end up with a weird streaking animation since there’s a delay before the div is hidden.
  3. Works in IE (just turned off the fade animation)

Php page redirection problem

by

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!
