How to make drop down selection to effect other types of fields

[MockY]

I have made a Mail form where the user chooses who he/she is from a drop down list, and depending on their choice, their email signature should appear in the <textarea>. How is that possible with PHP? Is it even possible, or do I have to use Java?

<textarea name="" cols="" rows=""><?=$value?></textarea>

is that what you mean

 

if you mean when the user change the value of select then something must happen you will need ajax but this can be done in php

This is what I mean:

 

<select name="from">

  <option value="none">Who Are You?</option>

    <option value="Mary <mary@mail.com>">Mary</option>

  <option value="Ryan <ryan@mail.com">Ryan</option>

  <option value="Sam <sam@mail.com">Sam</option>

  </select>

 

Now, let say Ryan enters the site and he wants to mail a specific person. So he selects his name. When that selection is made, his signature should automatically appear in the <textarea>.

 

And I wonder if this is possible somehow in PHP. If now, could you point me in the right direction (Ajax or something similar)

java script is the answer then u have to use the onchange="the function()" property of select option

I have been looking around, and can't say that Java is my strength. I found some what an example that might work here http://www.java2s.com/Code/JavaScriptReference/Event-Handlers-Reference/onChangeExample.htm

but I don't understand where to put the three different events that will happen once it is selected. Could yu help or point me in the right direction on some site?

 

All help is appreciated, thank you.

You have to stop saying Java. Java and Javascript are two completely different languages! Just a heads up
