[Resolved] array help???

[jazappi]

I have a form with about 50 text boxes named store_number. So when I hit submit it is an array. How can I write a little piece of code that looks at each check box and counts how many are filled out and tells me. This is how I print each number that is filled out. Now how do I count how many values are in the form?

  

foreach ($_REQUEST['store_number'] as $key=>$value):
  if ($value != ""):
      print ("<font size=\"2\" face=\"Tahoma, Arial\">$value, </font>");
  endif;  

endforeach;

I am assuming that it is something close to this, only using the count function in there somewhere, I just can't seem to figure it out. Any help would be great. Thanks!!!

To count the number of elements in an array, use count($arrayName).

BTW, you don't need to use endif or endforeach in PHP, you can just use braces. And if and if statement has only one statement to evaluate, you don't even need those. ie:

foreach ($_REQUEST['store_number'] as $value) {
  if ($value)
      print ("$value");
}

when I use:

$array_count = count ($store_number);

It is counting the form fields that are blank, so if the user fills out 4 out of 50 form fields, the count still comes back as 50 and not 4. Any suggestions?

foreach ($array as $value) {
    if ($value)
        $count++;
}

$count now equals how many keys have values assigned to them

so do I need to replace $array with my array name? and then how do I print $count?

figured it out, thanks so much for the help!!!
