If your whole JavaScript code gets processed by PHP, then you can do it just like that.

If you have individual .js files, and you don't want PHP to process them (for example, for caching reasons), then you can just pass variables around in JavaScript.

For example, in your index.php (or wherever you specify your layout), you'd do something like this:

<script type="text/javascript">
    var my_var = <?php echo json_encode($my_var); ?>;
</script>

You could then use my_var in your JavaScript files.

This method also lets you pass other than just simple integer values, as json_encode() also deals with arrays, strings, etc. correctly, serialising them into a format that JavaScript can use.

<form name="add" method="post">
     <p>Age:</p>
     <select name="age">
        <option value="1_sre">23</option>
        <option value="2_sam">24</option>
        <option value="5_john">25</option>
     </select>
     <input type="submit" name="submit"/>
</form>

You will have the selected value in $_POST['age'], e.g. 1_sre. Then you will be able to split the value and get the 'stud_name'.

$stud = explode("_",$_POST['age']);
$stud_id = $stud[0];
$stud_name = $stud[1];

The usual workflow:

Provide a Javascript rich-text editor for your users such as TinyMCE: http://tinymce.moxiecode.com/
Grab the source generated by the RTE and filter it through HTML Purifier before saving to the database.
Escape the existing HTML: <div id="myHtml" style="display: none"><?php echo htmlentities($html); ?></div>
Re-populate the RTE via Javascript - in the case of TinyMCE as follows: tinyMCE.activeEditor.setContent($('#myHtml').html());

You can also load the HTML content via AJAX.

In order to get your variables into the message, if you are using double quotes, you should just be able to include the variable in the string:

$message = "
<html>
...
<tr>
<td>$name</td>
</tr>
...
</html>
";

You can also break out of the string

$message = "
<html>
...
<tr>
<td>".$name."</td>
</tr>
...
</html>
";

Which will work with single or double quotes (personally I prefer this method with single quotes).

However when you receive this email, you will see the raw html. In order to have the html displayed properly you will need to set the appropriate mail headers. There are examples of how to do this here and here
