Getting Form Variables

MikeA

Ok, here's the problem.

     print "$default_right_line<input name=\"cat_check-$counter\" type=\"checkbox\" value=\"$hd_cat_id\">Check to Allow</font></font></font></div></td>";

Above you can see that it's naming the checkbox cat_check-$counter where counter is $counter += 1. So I'll have checkboxes named:

cat_check-1
cat_check-2
cat_check-3
etc.

So the problem is that if I have10 of these variables then it won't be a problem to just do an IF statement on 10 cat_check's. But what if the number could fluctuate. Maybe 5 one run, then 8 the next. How would you do checks on each of these? Is there a way to set the value of a variable INTO a variable?

Like $check = "cat_check-$counter" then turn the value of $check into it's own variable?

Is there an easier way to do what I'm trying?

for ($i=1; $i<=3; $i++)
  echo '<input type="checkbox" name="allowed[]" value="'.$i'.'" />Check to allow<br />';

will produce:

<input type="checkbox" name="allowed[]" value="1" />Check to allow<br />
<input type="checkbox" name="allowed[]" value="2" />Check to allow<br />
<input type="checkbox" name="allowed[]" value="3" />Check to allow<br />

in the script processing the form do st like this:

for ($i=1; $i<=3; $i++)
  $allowed[$i]=(bool)(isset($_POST['allowed'][$i]))

Ok here's what happened. I don't know how many fields are going to be generated when the check boxes are made, so I pass a hidden field of the total that it generated called total_count. The first script is in a loop pulling information from a database to generate the checkboxes.

     print "$default_right_line<input name=\"cat_check[]\" type=\"checkbox\" value=\"$hd_cat_id\">Check to Allow</font></font></font></div></td>";

   for ($counter = 1; $counter <= $total_count; $counter++) 
      {
	  $cat_check[$counter]=(bool)(isset($_POST['cat_check'][$counter]));
	  print "$counter - $cat_check[$counter] .. ";
      }
	die();

If I select all the boxes then the output is something like this

1 - 1 .. 2 - 1 .. 3 - 1

But the data that's stored in $cat_check[$counter] (the hd_cat_id) isn't 1. At least not for all the fields, maybe one of them is.

Anyone else have a suggestion?

instead of echoing html go like this

if( blah blah)

{

?> //end tags

//put all the html u want to output here!

<html>

</html>

<php?
exit;

}

Ok, for the heck of it I started playing around with what I had and the following is what solved the problem:

FROM THIS:

$cat_check[$counter]=(bool)(isset($_POST['cat_check'][$counter]));

TO THIS:

$cat_check[$counter]=$_POST['cat_check'][$counter];

I think everything is working now.
