如何在PHP中将未经检查的框数据存储在数据库中？

Question

In PHP I used Multi check box in foreach loop, When I Unchecked then I want to count and store that data in Database and also for Checked data, so How can I do that? And I've a condition for that it is...

If(checked)
{
 Insert Present
}
Elseif(Unchecked)
{
 Insert Absent
}

Check box is in foreach loop, so there is multiple checkbox with different names.

Here presently I store data for Checked, but I can't store data for Unchecked, so please help me to solve this problem.

Lets go for pseudo logic for this.

Store a hidden variable with all the checkbox values.

e.g.

<input type="hidden" value="1,2,3,4,5,6,7,8,9" name="allCheckboxes"/>

In the form submit, you are already getting the checked values.

Say, you get 5,7,9 as checked. -> Present

You need then 1,2,3,4,6,8 as unchecked. -> Absent

This can be achieved through array and string operations between allCheckboxes and checked checkboxes.
