anyone know a lot? question concerns php also.

'cause i need someon knowledgable to answer my question.

k here is my page i need help with.

the plan: a user types in a name in the text box, clicks "add new name" link as many times as he wants and enters as many names as boxes or not. user clicks submit and the names are put into a xml file which will be used imediately afterward, but that's a question for another time.

what's going down: by clicking "add new name" a new text box is added into the div tags innerHTML. I need to figure out a way to keep the users entry, but that's not my question, though if you want to answer that go ahead.

my question: can the names of the new textboxes be seen by php's $HTTP_SERVER_VARS thingy? I need to know just so i know if my php code is bad, or if it just won't work with my javascript.

to see the javascript it's list.js in the same folder.
thnx

The inputs should come in as part of $_POST . You might try setting method="POST" instead of "post" if you're paranoid.

PHP doesn't see anything until you press the submit button. Once you press submit, if you have created an 'name' attribute for that element, then you would be able to access that variable with: $_POST['myvarname']

Using javascript for this might be a little more complicated than you need it to be. If I were saving names in an XML file, I would use this logic:

- read the xml file into an array
- display the names in the file on the page
- at the top or bottom of the page, have a text box and submit button to add a new name
- write a function to add a new name to the xml file if one is submitted
- also write a function to delete a name from the xml file and have a 'delete' link next to the name to trigger it

i really don't know the scope of your project and this may completely not apply to it, .. but definately get a handle on the PHP/XML stuff you want to do before you get too deep into the javascript.

yeah, i'm trying to get into this whole "AJAX" thing, it seems to be a must have for web developers so i'm trying to get acquainted with all that crap at the same time. hey it's fun.

you might want to check this out. it's not exactly writing your own from scratch, but it might be good if you want to work with a framework that is already made.

so here's my next issue, what I've done here doesn't work on IE. Most javascript seems to not. I did a calculator and that works fine, but this one wont show up at all.

can anyone help me try to get my javascript to work with it?

No it isn't, for example i hate AJAX due to the 'J' (javascript) things of it.
Keep in mind that many browsers allow you to disable JavaScript and not to mention the loads of IE's restrictions thanks to the many security issues with it unless you use P3P.
If you need something like AJAX think also about Flash and Java solutions.

Personally i just let people hit the [submit] button and provide them another form.

If you really want to do AJAX well it's best to take a while to study each component seperately before you try to combine them.
