Ajax form submission with tiny MCE editor

Hi,
I was working with a Ajax form submission where the form contains a tinyMCE wrapped
textarea. I was using prototype library for Ajax. Problem is when I called
Form.serialize('form_id'), it couldn't retrieve the value of the textarea as it is wrapped by
tinyMCE. At last I got a solution by just calling a tinyMCE method before the
Ajax operation. Here is the stepwise detail:

1. My tiny MCE declaration was very simple like:

<script type="text/javascript" language="Javascript">
    tinyMCE.init({
        theme:"simple",
        mode:"exact",
        elements:"desc"
    });
</script>

2. Following is my HTML form:

<form onsubmit="return processForm()" name="submitForm" id="submitForm" method="post" action="request.php">
    <label for="name">Name: </label><br />
    <input type="text" name="name" id="name"><br />
    <label for="desc">Description: </label><br />
    <textarea id="desc" name="desc"></textarea><br />
    <input type="submit" value="Submit">
    <div id="response" class="message" >response will be shown here....</div>
</form>

3. My Javascript function:

function processForm(){
    tinyMCE.triggerSave() #IMPORTANT!!
    params = Form.serialize('submitForm')
    new Ajax.Updater('response','request.php', {
        parameters: params }
    );
    return false
}

4. Ajax requested is processed by the following code:

<?php
$response = "";
$response .= '<h3> Hi '.$_POST['name'].'!! Thanks for submission</h3>';
$response .= 'Your Message:<br />'.$_POST['desc'];
echo $response;
?>

Note the calling of tinyMCE.triggerSave()
function. By calling this function you will get the formatted written content in actual text area that you created in the form. Then you can get this value in a serialized format for ajax request by only a simple call Form.serialize()
of prototype library.

Eventually you can get the formatted value of the textarea by callingdocument.getElementById('text_area_id')
For example in this case: document.getElementById('desc')

I would like to have comments with better suggestions or details of using ajax with tinyMCE.
Thank u.

File Hosting & File Sharing

Hi
I was searching for a free file hosting web site for last few days where i can upload my necessary files. I also want those to be shared with others. I found some sites like: adrive.com, 4shared.com, megauploader.com etc. The main problem I felt with these sites is the uploading process. They are using some kind of ajax process or flash file uploading system which dont perform well in a slow internet speed.

However I found a site. It is filefactory.com. Personally I am loving this one because its file uploading system seemed convenient to me. You will have a link to the page of your uploaded file which can be distrubuted for sharing.
You can upload files

1. Without registration
2. Free membership
3. Premium membership

You will also be awarded with few points on each download of your uploaded files. They will provide a refferal link that can be used in the new registration process with your referral. Like you can register by simply clicking here to make me as your referral (appreciable!).

So, at last, i am really enjoying the site. It is really appreciable if anyone can suggest any other web sites for these purpose.

Thank you.
