echo a variable in a form based on user selection

[jeff5656]

Here's part of the form:

<select name = "pulmonologist" >
<option selected="" value="">---Select---
<option value="none">None</option>
<?php		
while ($row2 = mysql_fetch_assoc ($results2)) {   
        ?><option value = "<?php echo $row2['staff_name'];?>"><?php echo $row2['staff_name'];?></option>
<?php }
?>
</select>

 

Ok now I want to echo the value that the user selects in the SAME page  (i.e. before the submit button is pressed) like this:

 

<input type="submit" value = "Contact <?php echo $pulmonologist;?>" />

 

Do you have any thoughts on how to do this?  Thanks!

you can't do it with php, you'd have to use javascript

Ugh.  Ok I'm off to google in search for a javascript forum (and I know nothing about javascript other than downloading pre-made js scripts, so wish me luck :-)  )

You'll basically have to have a function that is initiated when an option value is selected... and have that function change the value of your submit.

Can you show me an example of how to do that with a function?  I have (probably stupidly) avoided learning functions yet so I do not know how to go about doing that.

We have a javascript sub-section: http://www.phpfreaks.com/forums/index.php/board,6.0.html

How to change a submit button via select value.

 

The first result looks promising.
