Filtering lists

Aurlito

I'm making a list that people can filter it by categories and supplement it to their preference, like bulletin boards' PM lists. but inevitably for a newbie who hasn't even written a static page, I've encountered a huge problem.
here's what I've done.

<?php
$int=0
funtion set_int($opt_int)
{
$int=$opt_int
in here I used head() to refresh the page, but it didn't work.
}

if ($int==0)
{ echo "the original list" I used ordered list tag, and it didn't work. (I used both apostrophe and escape), is there an alternative way to make lists in PHP without using HTML?}

if ($int==1)
{Filtered list}

if ($int==2)
{ filtered list 2)

//and this pattern goes on.

I use this to trigger opt_int()

But it doesn't work. what should I do?

Aurlito

<option onclick="opt_int(1)"><List Filter 1></option>

Of course I don't use these in my code, :d they just unintentionally came out of nowhere.

Oh I figured it out, I have to make a cookie. I'll do it and if there was problem, I'll ask again.

WOW, your code is confused. I can't understand what exactlu you want to do.

If i not wrong, from what I see and understand, I think you are trying to make a page redirect (reload) when some user select some option from Select-list.

To do this you can create form and place the Select inside. After that you can do attach to onchange select's event some javascript wich submit the form. After submit form in $_POST array you have user select choise and can filter а display result by selected option.

So you're simply saying to use Ajax? can you be more explicit? some thing like this would work right?
<script type="text/javascript">
//normal xmlhttprequest stuff blah blah blah.
....
xmlhttp.open("GET","list.php?int=",true);
xmlhttp.send();

and the form you're referring to:

<form action="list.php" method="get">
//the select tag
<input type="submit" />
</form>

Am I doing it right? please correct me if I neglected something in xmlhttp.open().

Thanks.
