checkbox limiter --->>

[Anon]

Hey Ya'll,

Say I have 6 checkboxes (<INPUT TYPE="checkbox" NAME="test">test ) ...........

I want to be a limit of 3 to be 'checked'.....so that a php string checks which if the 6 checkboxes are '1' and if there are more then 3 checkboxes are '1', php breaks

is this possible?

mail me,
Niels

Well, you can write some messy function for that...

like,

function check_checkboxes() {
global $allthenames,...;

$x = 0;

if ($checkbox_name) {
$x++
}
... do this for all the names
//close function
}

Or just do exacly that without functions,
and then check if x < 3...

BTW, don't mind of the function... I create function for everything anyway 🙂

If you let them be returned in an array, like this...

<INPUT TYPE="checkbox" NAME="test[]">test

...you can easily check sizeof($test). Only those boxes that were checked will be included in that array, so if (sizeof($test) > 3) then bugger off! ^_

I was trying to use u'r function to create a checkbox limiter (so a user is only alowed to check 3 boxes) but i'm getting an parse error and it's pointing at } on the 6th line. What is wrong? Thanks. 🙂

function check_checkboxes(){
global $name, $address, $SS, $CC;
$x = 0;
if ($checkbox_author) {
$x++
}
if ($checkbox_title) {
$x++
}
if ($checkbox_comment) {
$x++
}
if ($checkbox_name) {
$x++
}
}
