if you used any value other than 0 it will insert
or you can check it before inserting when it is empty you can insert 0

I don't know that a zero would be a problem.  What type of field is Completed in your database?  You are checking the checkbox correct?

Part of me thinks you aren't and assuming the form sends the value anyways.  Maybe that assumption is wrong but I thought it was worth checking.  The form will only send the name and its value if the box is checked.

In your PHP script echo the value of $_POST["C1"] to see if the script does get the 0.  What is the result?

Let me know if you have a question or need more information.

bol,

If the box is checked or unchecked it send out the "0" value in the database

complete is int field.... in database

In not all cases I am checking the checkbox... I might check or I might not check...

if checkbox is not checked I want "0" in database
if checkbox is checked I want "1" in database...

That is your solution
if you check the box it will send the 1 and it will inserted in the db
if you didn't check the box it will send nothing and the if condition will fill the variable with 0

>> If the box is checked or unchecked it send out the "0" value in the database <<
What do you mean.  If the form field isn't checked then that checkbox name and the value 0 aren't in $_POST.

>> if checkbox is not checked I want "0" in database
if checkbox is checked I want "1" in database...  <<

If that is what you want to have happend then you should use ...

if (isset($_POST["C1"])) {
    $c1 = '1';
} else {
    $c1 = '0';
}

$sql="INSERT INTO requests (Request, Type, Completed)
VALUES
('$_POST[S1]','$_POST[D1]','$c1')";

If the database field is a type of number then you probably don't need the single quotes around that value.

Let me know how that works or if you have a question.

@mukhtar2t - You have 2 major errors in the proposed code.  Besides missing brackets for the If statement you can't use $_POST[] like variables to be set or changed.

A correction to my comment to Mukhtar2t.  Mukhtar2t, I'm sorry, PHP does let you change $_POST[].  For example, $_POST["C1"] = "changed"; would make that "changed" instead of the value sent from the form.
