Checking if checkboxes, created from while loop, are checked

Hi Sitepointers,

I have a small problem finding a solution for my following problem:
I need to check many checkboxes (created form a loop) to see if they have been checked.

I create the checkbox form fields out of a sql table using a while loop like this:

while ($r = mysql_fetch_array($result)) {   
    extract ($r);
   
   echo "<input type=\"checkbox\" name=\"offer$id\" value=\"$headline, \"$check>
";       
    }

}

Code (markup):

The HTML of the output would look something like this:

<input type="checkbox" name="offer1" value="Adventure Offer A, ">
<input type="checkbox" name="offer2" value="Adventure Offer B, ">
<input type="checkbox" name="offer3" value="Adventure Offer C, ">
<input type="checkbox" name="offer4" value="Adventure Offer D, ">
.
.
.
and so on
 

Code (markup):

This is great an lets me dynamically create as many checkboxes as needed depending on the offers in the database.

However how can I check which ones of them have been checked?

If there'd be just one with a fixed name I'd do something like this in the while loop:

if ($offer1 == "$headline, ") {$check = "checked";}
else {$check = "";}

Code (markup):

However now I get more than 1 offer, I get $offer1 $offer2... and so on.

How can check on each one???

I tried and all my ideas failed, any help out here?

Thanks a lot.

Copy & Paste job, eh...

Anyway, your question has already been answered there.

 

LOL you got me yes,

sorry about that totally forgot to change :|

Yes has been answered there but I'm still stuck, I don't seem to be able to code it. I'd need a small sample. Never coded that way before

Anyone wants to help providing a short sample for me??

here's the answer I got from sitepoint:

Thanks
