IDE :: Dynamic Text Variabes To A Form PHP Script For Emailing?

If a user makes a number of selections from visual indicators on frame 1 of a Flash 8 file and textual descriptions of those selections are then actionscripted into dynamic text boxes as text values in a form on frame 2, can the text values of the dynamic text boxes be given variable names that can be sent to and processed by a server-side PHP script as regular input type text box variables would be processed?

Example: User selects 3 images on frame 1 via a mouse on(release) event.

the actionscript being:
on(release) {
form.dynamicTextBox1.text == "Image 1";[code]....

On the form frame (frame 2) would be a movie clip (form_mc with instance name form) with the normal Name, Email, Message input type text boxes along with dynamic text boxes dynamicTextBox1, 2 and 3.On the form Submit button the actionscript would be:

on(release) {
var sendVar = new LoadVars ();
var receiveVar = new LoadVars ();[code]....

If the input text boxes are give variable names (i.e. var userName, var userEmail and var userMessage) can the dynamic text boxes be given variable names also that can be passed to the server-side PHP script (i.e. var dynamicText1, var dynamicText2 and var dynamicText3)
where the PHP might look like:

<?php
$to = "me@mywebsite.com"
$subject = "email enquiry"
$name = $POST['userName'};[code].....

Would this work? All indications I have seen through many Flash/PHP email tutorials indicate not using dynamic text boxes but components like combo boxes etc use variables and not input boxes.
