You might want to start by reading the PHP manual about GET and POST vars and how to read them.
Look at track-vars and HTTP_POST_VARS and HTTP_GET_VARS.

I think you can do this through java script's validation and then pass it to php script..mail me if you cant get it..

your checkbox is something like that (inside a form):

<input type="checkbox" name="checky" value="something">

when subimited, if it was checked, you get a variable named $checky, with the string 'something'...
if it wasn't checked, you has a variable $checky with the string 'none'.
.. nothing that you couldn't find yourself with one or two echos.

If it isn't checked, the value of $checky is null. i.e. it's nothing. So if you want to do something if the box is checked or not, do this...

if ($checky)
{
//yes, it's checked
}
else
{
//nope, not checked
}

You can use if(isset($checky)) or if ($checky == "")....depends on your flavor..

here's the script i ran... http://www.sepodaticreations.com/test/test2.php3

(maybe it's 'none' in ph4, but I don't think so...)

10x for helping me ... but its still a problem .. I have a lot of them on the page .. and Their names are created like

$cheky = "check".$row['id'] (taken from database)

<input type=checkbox name=$cheky>

and after page was created I have a lot of check boxes with names chek1, check2, check120912 ... check120342 ...

and now I would like to get wich are checked on submit !!!!

You can read the manual on variable variables, it'll help you with this naming technique.

A better options would be to name all of your checkboxes something like this:

<input type=checkbox name=checky[] value="<? echo $row[id]; ?>">

This creates an array of your checkboxes, no matter how many there are. Then you just loop through them in your processing page to see how many are checked.

untested
for($count=0;$count<count($checky);$count++)
{
if ($id_val = $checky[$count])
{
echo "Box for Row $id_val CHECKED";
}
else
{
echo "Box for Row $id_val NOT CHECKED";
}
}

Let me know if you have any questions.
