Thanks in advance.

isset() is your friend.

if(isset($HTTP_GET_VARS['i']) && $HTTP_GET_VARS['i'] == '')
{ include('myfile.php'); }
This will not trigger any warning, even under E_ALL.

In response to some of the other posts, developing at E_ALL is a good 
idea as it'll help you spot potential problem areas.

Also, even though you have a form element defined, it may not always 
appear in $HTTP_GET_VARS/$_GET (post, etc). One example are checkboxes. 
If no boxes are checked, the variable is never created and this is the 
way to check.

error_reporting(E_ALL) tells me that I have an indefined index, but as Jon
Kriek pointed out,
perhaps reporting "all" the errors is not such a "good thing".

Why would you want to declare a GET or POST variable in the first place?
You'd be overwriting whatever value was stored from the form.

Also, depending on your version of PHP you should be using $_GET and
$_POST and not $HTTP_GET_VARS or $HTTP_POST_VARS.


hth,
Chris.

[PHP] Undefined Index - is this how you "declare" get & post?

[Terence]

Hi List,

Since I started using error_reporting(E_ALL), I havent found (in my opinion)
a good way to declare GET and POST variables when getting them from a form
or querystring. I have searched google and the docs for several hours now
without much luck.



Is there a better way?
I have tried var $i (only for classes I've discovered)
settype($i, "integer")

Thanks in advance.
