remembering a passed through variable

[-[Bl@de Runner]-]

Hi guys,

I pass, with the URL, a variable through to a page in my site.
Let's call the variable 'index'.

In that page a submit happens when you press a button.
And then, when you press that button, I want to use that variable, but at that point the variable is 0.

How can I store this variable somewhere so that when I press the submit button, it still knows the value of the variable ?

Store it as a cookie or session value, or if you've got a form that you're using, store it as a hidden field in that form!

Like this ?

<input name="forumIndex" type="hidden" value="$fIndex">

Cause when I type this:

echo "$forumIndex";

It gives me the following result: $fIndex which is wrong

i did it with : value="<?php echo "$fIndex"; ?>"

You could just do value="<?=$fIndex?>"

Hi interesting whats is mean "=" in your script, - never use this....

It's take from ASP I believe. It just means to output quickly, an alternative to echo or write! Very good for writing small scripts, and you can even use it with functions, eg:
value="<?=$url.$page.urlencode($someVariable)?>"

Or even:

value="<?=($value)? "Yes":"No"?>"

You just use it for single line scripts!
