TinyMCE Jquery not working fine

Hi I had used TinyMCE in my code single page code to upload data into server using TinyMCE. My Code is as follows, this is the add.php page :
<?php
$msg="";
include("config.php");
if($_POST['title']!= ""){
$title= $_POST['title'];
$words= $_POST['words'];
$words= stripslashes($words);
if (!$title)
{
$msg="Please Enter Title";
} elseif (!$words)
{
$msg="Please enter the Blog";
}
$query= mysql_query("INSERT INTO editor (title, content) VALUES ($title, $words)") or die (mysql_error());
$msg="Success!";
}
?>

<p><b>Add a New Blog</b></p>
<form action="add.php" method="post">
Title of the Blog :

<br/>
<input type="submit" value="submit"/> <?php echo $msg; ?>
</form>
</div>
</body>
</html>
My Textarea is displayed as a normal textarea, the data is also not going into the Database.
The config.php file is for Database connection and it is working fine, I checked it.
Please help, Thanks in advance.

You forgot to add extension in linked script file
<script type="text/javascript" src="jquery-1.11.0.js"></script>
<script type="text/javascript" src="tinymce.min.js"></script>
<script type="text/javascript" src="jquery.tinymce.min.js"></script>
Check this Sample Demo
I think you are added two TinyMCE library so it's may be conflict problem. So please update only this two library
I am add only 2 library
JQuery Library - http://code.jquery.com/jquery-1.11.0.min.js
TinyMCE Library - http://tinymce.cachefly.net/4.0/tinymce.min.js
And In your Header add this script
<script>
tinymce.init({
selector: "textarea"
});
</script>
try now its work.

$.get command in jQuery goes wrong

I am new in jQuery and need help to figure out why $.get does not reply.
Let me explain what I have: There is a main index.php as follows:
<!DOCTYPE html>
<html lang="en">
<head> <meta charset="utf-8"> </head>
<body>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript" src="js/reqhan.js"> </script>
<input id="string" type="text" />
<input id="button" type= "button" value="Go" />
<div id="div"></div>
</body>
</html>
the js/reqhan.js contains
$(document).ready(function(e) {
alert('1');
$('#button').click(function() {
$.get('php/reverse.php',{input: string},function(data){alert('2');});
$('#div').text(data);
alert('3');
});
});
and reverse.php contains a simple code (I pasted here but does not preview it) that gets the text from reqhan.js file and returns an echo message.
when running the code on Google Chrome, the first alert is shown but not the rest and of course the `$('#div').text(data);' doesn't send back the data to the js file.
Please let me know if further info is required.
many thanks.
You're closing your callback function before you do anything with the data
Try this instead:
$(document).ready(function(e) {
alert('1');
$('#button').click(function() {
$.get('php/reverse.php',{input: string},function(data){
alert('2');
$('#div').text(data);
alert('3');
});
});
});
Try to format your code so that each pair of brackets gets its own indentation. It should help catch small things like this.

AJAX/PHP simple code fails to work

I was following a tutorial to understand how AJAX/PHP works but i'm having an issue.
Let me start with the code.
escalationTest.php:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<form>
<input type="text" id="name" placeholder="Enter Name.." /> <br>
<input type="text" id="age" placeholder="Enter Name.." />
<input type="button" value="Submit" onClick="post();" />
</form>
<div id="result"></div>
<script type="text/javascript">
function post()
{
var name= $('#name').val();
var age= $('#age').val();
$.post('escalation.php',{postname:name,postage:age},
function(data)
{
$('#result').html(data);
});
}
</script>
</body>
</html>
escalation.php:
<?php
echo "working";
?>
I've typed the code exactly how its in the tut. From its output when i click the submit button i should "working" in the result div which is not happening.
What am i doing wrong here..?
Thanks.
<script type="text/javascript" src="jquery.min.js"></script>
Download a version of jQuery and then link to it with this script tag.
While you can link to an online version, it's not ideal for eventual production use and you should definitely get a local copy.
add the folowing line to your head tag
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
This is a pretty simple fix - you're missing jQuery. Add the following:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
in your head element.

Pass global javascript variables to php

I have a index.php file where I have canvas game. This game is loaded from separate game.js file where I have variable: ballsCought. I want this wariable and name inputet to text input pass on click to another php file. my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Simple Canvas Game</title>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function(){
function score(){
$('#score').fadeIn(1000);
$('#score').load("load_players.php");
};
setInterval(score , 1000);
var nam = $("#name").val();
$('#submit').keyup(function(e){
if(e.keyCode == 13){
$.post('upload_score.php','n=' +nam, 'score=' +ballsCought);
}
});
$('#submit').click(function(e){
$.post('upload_score.php','n=' +nam, 'score=' +ballsCought);
});
});
</script>
</head>
<script src="game.js"></script>
<body>
<canvas id="canvas" width="525" height="525"></canvas>
<br /><p><span id="points"></span><input type="text" id="name" placeholder="Name..."/><input type="submit" id="submit" value="Submit"/></p>
<br /><span id="score"></span>
</body>
</html>
But this post function is not working any idea? THank you...
Looks like your $.post method is not correct. If you want to pass data to the PHP page you need to use the JavaScript object notation like so:
$.post('upload_score.php', {n: nam, score: ballsCought});
You can read more about the various ways to call $.post from the jQuery Docs page
Now there could still be problems with your PHP page. You should use something like Firebug to see the Ajax request and any errors that might be returned.
