I am able to get the value of elrte inside the javascript variable, but now I wanted store this value inside the mysql database, as I am using PHP I want to access this value inside a php so that I can store it in database, I tried using window.open("abc.php?val="+content); but the value is very large so get method cannot be acceptable here, so is there any way to get this value inside the php? or any alternate way to do this?
** Edit :**
Now it gives me a value of content variable after making following changes, but I want all 3 variables, but unable to get
$('#btnsub').click(function() {
var content = $('#editor').elrte('val');
var title = document.getElementById('atitle').val;
var tag = document.getElementById('atag').val;
alert('title'+title);
$.ajax({
type: "POST",
url: 'abc.php',
data: {title : title, tag : tag, content : content},
success: function(html) { $('result').append(html); },
dataType: 'html'
}).done(function( msg ) {
alert( "Data Saved: " + msg );
});
and php file
<?php
include('inc/conn.php');
if(isset($_POST['updabt']))
{
$cont=$_POST['updabt'];
$q1=mysql_query("update aw_about_us set abt_title='$title', abt_small_line='$tag', abt_content='$cont'") or die(mysql_error());
if($q1==true)
{
?><script>alert("Page Updated Successfully!!");</script><?php
}
else
{
?><script>alert("Page Not Updated!!");</script><?php
}
}
?>
Now how to get all three variables??

You'll need to submit the value to your PHP script using a POST request to your server. You can do this with Ajax requests, and I believe jQuery has built-in methods for Ajax which are cross-browser.

This is not a terribly useful answer. Use of the word 'believe' tells me you're not sure of the answer. Yes, jQuery has a number of AJAX functions that will do what the asker wants. But you haven't explained how.
Mike Gallagher
I did explain how... I just didn't give code. Googling "Ajax POST request jQuery" gives the following result with a clean easy-to-read example on the first page: stackoverflow.com/questions/5004233/jquery-ajax-post-example
Mike Gallagher
The link I supplied gave a good example. You can also look into jQuery's $.post() function. It simplifies giving data to a PHP script from JavaScript.
Mike Gallagher
There is a PHP configuration setting called 'register_globals'. It automatically creates '$varname' variables from the $_POST and $_GET arrays before it starts executing your script. However, for security purposes, it is normally disabled. It is better practice to reference all variables using '$_POST['varname']' or '$_GET['varname']' so you don't depend on the feature being turned on.
You need 2 pages, one which will send AJAX (this you have) and one wich will respond (below):
<?php
///ajax.php
if(isset($_POST['updabt']))
{
extract($_POST);
$q1=mysql_query("update aw_about_us set abt_title='$atitle', abt_small_line='$atag', abt_content=''") or die(mysql_error());
if($q1==true)
{
?><script>alert("Page Updated Successfully!!");</script><?php
}
else
{
?><script>alert("Page Not Updated!!");</script><?php
}
}
?>
In javascript you create AJAX post
data['updabt'] = '';
$.ajax({
type: "POST",
url: 'ajax.php',
data: data,
success: function(html) { $('result').append(html); },
dataType: 'html'
});

I don't agree that the asker needs two "pages". With some clever use of params it can be done with one script. You're also sending an empty string (to what end I don't know), and there is no purpose to the
success action. The ajax.php does not echo anything. The JavaScript in ajax.php will not work because the script is not handled in the browser but in a separate thread that is handled on the back end.Igor S.
@GordonFreeman First it needs to work, then optimization. OP is not skilled enough to understand all the "tricks" for one page.

I added this, $('#btnsub').click(function() { var content = $('#editor').elrte('val'); var title = document.getElementById('atitle').val; var tag = document.getElementById('atag').val; $.ajax({ type: "POST", url: 'abc.php', data: data, success: success, dataType: 'html' }); }) but still not works...
Igor S.
If you call your own page, you cannot display results (because the result is all new page) or you need to disable returning anything when isset($_POST['updabt'])
Darpan Kulkarni
Its ok if I cannot get results but data is also not gets added in database

You can use AJAX (easiest with a library such as jQuery) to submit the variables to another PHP script that will INSERT the values to your database.
Start by reading the following...
This is actually very simple once you get your head around the subtleties of AJAX.
Here is a simple example to get you off and running. Suppose you wanted to log something to your PHP error log...
This would be my JavaScript function:
var log = function(val) {
$.post("ajax.php", {"mode": 'log', "val": val}, function() {});
}
ajax.php would be a collection of functions, ideally a class...
public function __construct() {
$arrArgs = empty($_GET)?$_POST:$_GET;
/**
* using 'mode' I can send the AJAX request to the right method,
* and therefore have any number of calls using the same class
*/
if (array_key_exists('mode', $arrArgs)) {
$strMethod = $arrArgs['mode'];
unset($arrArgs['mode']);
$this->$strMethod($arrArgs);
}
}
protected function log($arrArgs) {
error_log($arrArgs['val']);
}
The same idea can easily be adapted to write data to a database.
