How do we check whether the checkbox is checked or not in php?

[Rinson Mathews]

The part of my code where I am using the check box is given below:
In the html part:

<TD bgcolor="#FF0000"><Input type = "checkbox" Name = <?php "Save_" . $row["ID"] ?> Value = "YES" /></font></TD>

Since I need different names for check boxes according to the number of rows retrieved from the database,I am using rowid to identify the check box.

In the php part:

If (@$_POST["'Save_" . $row["ID"] . "'"] == "YES"){
echo 'Starting Updation';
}

Then I used the below code also........

If (@$_POST["Save_" . $row["ID"]] == "YES"){
echo 'Starting Updation';
}

Both of them are not working................
Plz help me to solve this problem...........
Thanks in advance

unchecked checkboxes are not passed to the server.

Hi Dormilich........
Thanks for your quick reply,but I didnt get the point.Here I checked the checkboxes which are required.

you should remove the @ before $_POST and set full error display. PHP usually tells you if something is wrong.
