Javascript Date Validation / Comparison

2009-11-26T11:40:00.002+05:30

Problem:
User enters two dates, say start date and end date, then we need to alert him if the start date is greater than end date.

Solution:
Assume we are getting the date to the input field using a datepicker.

First we have to convert the string into Date() object using
var dObj = new Date(year, month, date); (also note: the month value range from 0 to 11)
and we can compare the dates.

Example:
var x = document.formName;

//assume the date format is YYYY/MM/DD
var sDate1 = x.start_date.value;
var sDate = new Date(sDate1.split('/')[0], parseInt((sDate1.split('/')[1])-1), sDate1.split('/')[2]);
var eDate1 = x.end_date.value;
var eDate = new Date(eDate1.split('/')[0], parseInt((eDate1.split('/')[1])-1), eDate1.split('/')[2]);
if(eDate >= sDate)
{
alert("End date is greater than start date; please try again....");
return false;
}

Disable Right Click using Javascript

2009-01-03T12:19:00.002+05:30

Simple way yo disable right click:
<body oncontextmenu="return false;">

Using script:
<script>
var isNS = (navigator.appName == "Netscape") ? 1 : 0;
if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP);
function mischandler(){
return false;
}
function mousehandler(e){
var myevent = (isNS) ? e : event;
var eventbutton = (isNS) ? myevent.which : myevent.button;
if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;

document.onmouseup = mousehandler;
</script>

From: http://www.reconn.us/content/view/36/45/

Now...
Can i disable right click only on images?
Yes, by using getElementsByTagName i can set no right click on images only

<script>
function noRtClk(){
return false;
}
//document.oncontextmenu = noRtClk;

var e=document.getElementsByTagName("img");
for(var i=0;i<e.length;i++)
{
e[i].oncontextmenu = noRtClk;
}
</script>

meta refresh problem in IE7

2008-12-11T14:28:00.002+05:30

this meta tag will redirect to the specified url in 3 seconds.
but it won't work in Internet Explorer 7.

BUT...
we can use a script...

function Refresher(t) {
if(t) refresh = setTimeout("document.location='http://www.mysite.com';",
t*1000);
}

</script>

Then call it inside body tag..

<BODY onLoad="Refresher(20)">

php explode and implode

2008-12-10T18:03:00.003+05:30

Use of Explode and implode functions

Explode - splits a string by a string
eg:
$a = explode("/","23/02/2008");
then
$a[0] = "23"
$a[1] = "02"
$a[2] = "2008"

Implode - joins array elements into string with a string

$b = implode("-",$a);
then
$b = "23-02-2008"

how to change the alert box title?

2008-09-25T12:49:00.002+05:30

Want to know how to change the alert box title in javascript...
the answer is: we cant change the title of js alert box.

however, we can use popup boxes, that look like alert boxes with custom title.... but there is a chance - some browsers will block that.
Or we can use vbscript msgBox, but cant get the result in FF.
Or we can use custom designs like this:
http://www.acejs.com/scriptsfolder/121015/121015.html

BUT it is not working like exactly as a alert box. (following codes will get executed though we dont click the ok button)

My opinion: Its better not to use any other custom alert boxes.

Change / Increase session timeout in php

2008-08-13T13:20:00.000+05:30

Projects using login may have the problem of expiring sessions in short time.
How to increase the session timeout in PHP?

use this as first line - before session_start
ini_set('session.cookie_lifetime',(3600*2));

In some servers it may not work.... BUT using .htaccess file it is working very fine.
Just place these lines in the .htaccess file and put the file in your root directory.
php_value session.cookie_lifetime 3600
php_value session.gc_maxlifetime 3600

and note these parameters are in seconds.
Then how to check the current session timeout?
use this:
printf("cookie: %s, gc: %s", ini_get('session.cookie_lifetime'), ini_get('session.gc_maxlifetime'));

Thats all.

Random Number / Alpha Numeric Password Generation in PHP

2008-07-23T12:45:00.000+05:30

To generate random no.s we can use rand() function...
try,
echo ran() ; //will generate random no between 0 and32768
echo rand(5,200); //a random no between 5 and 200

To generate alpha numeric random no - uniqid()...
try,
echo uniqid(rand(), true);
you can get a number like: 274134886dbd37292e8.16885304 (32 digit)

To generate alpha numeric passwords for user accounts use this:
$password = substr (MD5(uniqid(rand(),1)), 3, 10); //10 digit random alpha numeric password

Div over flash problem in HTML

2008-06-27T13:17:00.000+05:30

Some may have this problem.
Always the flash object looks like placed in front of all the objects. So if we want to put a div in front of flash/ over flash we cant.

But there s a solution...
The normal flash object....
<object classid="clsid:D27CDB6E-AE6D-11CF-96B8-444553540000" id="obj1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" border="0" width="519" height="255">
<param name="movie" value="center_flash.swf">
<param name="quality" value="High">
<embed src="center_flash.swf" pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" name="obj1" width="519" height="255" quality="High">
</object>

To make it back of all elemnts add
<param name="wmode" value="transparent">

So the actual code we want is...
<object classid="clsid:D27CDB6E-AE6D-11CF-96B8-444553540000" id="obj1" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" border="0" width="519" height="255">

No of days between two dates in php

2008-05-23T17:28:00.000+05:30

We can find the no days between two dates using PHP....
There are 2 methods:

1) Split the date and subtract
$date1 = "2008-05-18";
$arr = explode('-',$date1); //split the date
$date2 = $arr[2]; //stores 18
$cur_date = date("d"); // current date
echo "Difference: ";
echo $cur_date-$date2;

2) Convert dates into timestamp, subtract and then convert as we want
$date1 = "2008-04-18";
$to_day = date("Y-m-d"); //current date
$day_diff = (strtotime($to_day)-strtotime($date1))/86400; //60*60*24=86400
echo $day_diff;

//change the divider(864000 to get ur corresponding difference
$hour_difference = (strtotime($to_day)-strtotime($date1))/3600; //60*60=3600
$week_diff = (strtotime($to_day)-strtotime($date1))/604800; //60*60*24*7=604800

Use of === and !== operators in PHP

2008-04-22T15:36:00.000+05:30

=== (identical)
$a === $b : TRUE if $a is equal to $b, and they are of the same type. (introduced in PHP 4)

!== (Not identical)
$a !== $b : TRUE if $a is not equal to $b, or they are not of the same type.

Example:
<?php
$a = "1"; //String
$b = 1; //Integer
if($a == $b)
echo "Equal<br />";
else
echo "Not Equal<br />";

if($a === $b)
echo "Identical<br />";
else
echo "Not Identical<br />";
?>

Output:
Equal
Not Identical

Difference between echo and print in PHP

2008-04-15T12:43:00.000+05:30

1. Speed.  There is a difference between the two, but speed-wise it
should be irrelevant which one you use.  echo is marginally faster
since
it doesn't set a return value if you really want to get down to the
nitty gritty.

2. Expression.  print() behaves like a function in that you can do:
$ret = print "Hello World"; And $ret will be 1.  That means that print
can be used as part of a more complex expression where echo cannot.  An
example from the PHP Manual:

 $b ? print "true" : print "false";

print is also part of the precedence table which it needs to be if it
is
to be used within a complex expression. It is just about at the bottom
of the precedence list though.  Only "," AND, OR and XOR are lower.

3. Parameter(s).  The grammar is: echo expression [, expression[,
expression] ... ] But echo ( expression, expression ) is not valid.
This would be valid: echo ("howdy"),("partner"); the same as: echo
"howdy","partner";   (Putting the brackets in that simple example
serves
no purpose since there is no operator precedence issue with a single
term like that.)

So, echo without parentheses can take multiple parameters, which get
concatenated:

 echo  "and a ", 1, 2, 3;   // comma-separated without parentheses
 echo ("and a 123");        // just one parameter with parentheses

print() can only take one parameter:

 print ("and a 123");
   print  "and a 123";

Sending HTML Mail in PHP

2008-03-12T23:53:00.000+05:30

To send HTML mail in php use the following code...

$to  = 'some@example.com';

$subject = Testing Html Mail;

$message = '

// HTML code here
';

// To send HTML mail, the Content-type header must be set
$headers  = 'MIME-Version: 1.0' . "\r\n";
$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";

// Additional headers
$headers .= 'To: Somebody ,' . "\r\n";
$headers .= 'From: Me ' . "\r\n";

// Mail it
mail($to, $subject, $message, $headers);

- This is not an Authentication Mail.
