updating a field from user input

Jiminizer

i know a tiny bit about php, and i can just about link a form to a database, if i keep looking at an example script ive got.

i'm using dreamweaver

what i need to do:

users select an item from a drop down menu, this updates a box to the right with the price. they then click a button, and the data is stored on a page for viewing, and sent as an email.

i have the menu, but not the auto updating box.

i can get it to go on to the data page (i have a script to work from), but not to an email.

please help me

Have you learned about the PHP mail() function? If not, read this: http://us2.php.net/manual/en/function.mail.php

Do you want to show us the code that you currently have?

<form method="POST" action="submit.php">

  <p>Processor:&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 
    <select name="cpu" size="1" id="cpu">
  <option selected>AMD Sempron 2200+</option>
  <option>AMD Sempron 2600+</option>
  <option>AMD Athlon XP 3000+</option>
  <option>AMD Athlon XP 3200+</option>
  <option>AMD Athlon 64bit 3500+</option>
  <option>AMD Athlon 64bit 3800+</option>
  <option>AMD Athlon 64bit 4000+</option>
  <option>AMD Athlon X2 Dual Core 4400+</option>
  </select>
    <input type="text" name="textfield">
  </p>

it would be the same for other items

imnot sure what type of form component to use instead of input type"text"
but it needs to be an output so it is not right.

i know the rest of it works. i also have a dbconnect.php file, a submit.php file vieworders.php and delete.php

If it comes to the worst, i can always add the price to the end of the items name,but it would look better in a seperate box. it could be handy if i did have the seperate boxes, and something to add the contents together together to give you a total price.

Best way is to do it with javascript. Have a look at this simple tutorial
http://www.javascriptkit.com/javatutors/form1.shtml
- it shows you exactly how to do what you want including calculating the total.
