checkbox & post vars

[jacinthe]

'morning!

i'm making a dynamic form. For each row in the table, i display it on the screen so that the user can change any value (except the key). And I name the textfield dynamically with a counter like this :

<input type="text" name="nopage_<? echo $ctr ?>" size="10" maxlength="10" value="<? echo $contact->no_page?>">

and when the user press the button update, I retrieve data with

while(list($key, $value) = each($HTTP_POST_VARS))

My problem : I have a checkbox for each row. When the check box is checked, i can see it in the post vars, but if I unchecked it, it do not appear anymore in the post vars.

Why is that?

That cause me extra coding to detect if it's in the list or not. . .

Thanx for any help,

cheers

check boxes are not passed into a script if they are not checked. so, a good way to check if a checkbox was checked is to use the isset() function. this will let you determine if the checkbox was checked and will not return the error message a boolean check will if the variable does not exist.

I wonder why checkbox are not passed if they are not checked. What's the point to pass them if they are, and not pass them if they are not. From my actual point of view, its complicating our coding job for nothing.
