Remaining Characters Counter


To find out how many characters remaining in input box or textarea when user type, like we see in Twitter or Delicious and other sites as well.

twiiter-character-counter

Add this code in your input box or textarea.

onfocus="characterCount(250, this.id, 'whyMeCount');"  and  maxlength="250"

where,
250 is the number of characters you what the box should take. You can change it as per your need.
whyMeCount is the id (#whyMeCount) of the html element where you want to display the count
and, whyMe id the id of the element on which we need to count characters on.

Example: 
<textarea id="whyMe" onfocus="characterCount(250, this.id, 'whyMeCount');" maxlength="250"></textarea>
<div id="whyMeCount"></div>

Now, add this JavaScript function in your script tag

function characterCount( text_max, boxId, countId ){
	var text_length = $( '#' + boxId ).val().length;
	if(text_length > 0) {
		$( '#' + countId ).html((text_max-text_length) + ' characters remaining');
	} else {
		$( '#' + countId ).html(text_max + ' characters remaining');
	}
	
	$( '#' + boxId ).on('keyup blur', function() {
		text_length = $( '#' + boxId ).val().length;
		var text_remaining = text_max - text_length;
		$( '#' + countId ).html(text_remaining + ' characters remaining');
	});
}

Generate and Download .ics file for an event using jQuery


Here is the code to generate and download the .ics file for an event using jQuery.

var todayDate	= new Date();
var msgData	= todayDate.toISOString();
var startDate	= e.start.toISOString();
var endDate	= e.end.toISOString();

var icsMSG1 = "BEGIN:VCALENDAR\r\nVERSION:2.0\r\nPRODID:https://www.google.com/\r\nBEGIN:VEVENT\r\nUID:https://www.google.com/\r\nDTSTAMP:" + msgData + "Z\r\nDTSTART:" + startDate + "\r\n";

var icsMSG2 = '';
if(endDate != '') {
    icsMSG2 = "DTEND:" + endDate +"\r\n";
}

icsMSG3 = "SUMMARY:" + title + "\r\nEND:VEVENT\r\nEND:VCALENDAR";

icsMSG = icsMSG1 + icsMSG2 + icsMSG3;

$('.test-ics').click(function(){
    window.open( "data:text/calendar;charset=utf8," + escape(icsMSG));
});

and, add this line in your html code

<div><a class="test-ics">Add to Calendar</a></div>

replace e.start with your event start date & time
replace e.end with your event end date & time
replace title with your event title

Sorting a Multi-Dimensional Array with PHP


//an array of some songs I like
$songs =  array(
		'1' => array('artist'=>'The Smashing Pumpkins', 'songname'=>'Soma'),
		'2' => array('artist'=>'The Decemberists', 'songname'=>'The Island'),
		'3' => array('artist'=>'Fleetwood Mac', 'songname' =>'Second-hand News')
	);

The problem is thus: I’d like to echo out the songs I like in the format “Songname (Artist),” and I’d like to do it alphabetically by artist. PHP provides many functions for sorting arrays, but none will work here. ksort() will allow me to sort by key, but the keys in the $songs array are irrelevant. asort() allows me to sort and preserves keys, but it will sort $songs by the value of each element, which is also useless, since the value of each is “array()”. usort() is another possible candidate and can do multi-dimensional sorting, but it involves building a callback function and is often pretty long-winded. Even the examples in the PHP docs references specific keys.

Display Expire time in Days, Hours, Minutes and Seconds



<?php
date_default_timezone_set('Asia/Calcutta');
function datediff( $date1, $date2 )
{
$diff = abs( strtotime( $date1 ) - strtotime( $date2 ) );

return sprintf
(
"%d Days, %d Hours, %d Mins, %d Seconds",
intval( $diff / 86400 ),
intval( ( $diff % 86400 ) / 3600),
intval( ( $diff / 60 ) % 60 ),
intval( $diff % 60 )
);
}

print datediff( "2015-05-11 14:55:00", "now" ) . "\n";

How can we get the properties (size, type, width, height) of an image using PHP image functions?
