If you have multiple checkboxes on the same subject, you need to pass them as an array. You do this by appending brackets to the end of all the checkboxes name's. <input type="checkbox" name="delete_it ems[]" value="1" />
-- Assumes you're using POST --
Then, in PHP, you can traverse the array of selected checkboxes (if it exists) and perform actions on them accordingly. -
-
if ( count ( $_POST['delete_items'] ) > 0 )
-
{
-
foreach ( $_POST['delete_items'] as $key => $val )
-
{
-
echo "{$key} -> {$val}<br />";
-
}
-
}
-
else
-
{
-
echo "No checkboxes passed.";
-
}

Hi,
I have a form with 2 radio buttons (ACCEPT/REJECT). When the page is

Hello --
My form's cmdCancel button requires 3 clicks before the code in Cancel_Click
fires.
Each click prior to that success moves the highlight to the next field in

I placed a Breakpoint on the first command in the Click event ot cmdCancel.
It is hit after that third click of cmdCancel.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
