Re: Validation problem with array.

I think I might know what you are trying to do. You want to have a 
"name" associated with the skill (or skys or slus). You can use an 
associative array to "name" your array elements. In your form, you can 
change the array to be something like this:

skills[cooking]

skills[flying]

skills[walking]

...

Notice there are no quotes around the skill names. Now each array 
element has an array key that is a name. The computer doesn't really 
care, but it makes it easier for you to read your code. And you now 
have name/value pairs. You can process the array like this:

$skillNames	= array_keys($skills);
foreach($skillNames as $skill) {
	echo 'Skill: '.$skill.'  Value: '.$skills[$skill].' <br />';
}

Of course, instead of echoing you would do your validation or 
substitution.

After some back and forth posts here I had finally
thought my array issue was over, but!

To review I have 30 form elements on a page
10 are skill[]
10 are sky[]
10 are slu[]

I pass them as session variables

$_SESSION['skills'] = $_POST['skill'];
$_SESSION['skys'] = $_POST['sky'];
$_SESSION['slus'] = $_POST['slu'];

Then when everyting is passed into a database
transaction:

$skills = $_SESSION['skills'];
$skys = $_SESSION['skys'];
$slus = $_SESSION['slus'];

foreach($_SESSION['skills'] as $key => $skill)
{
$query = "INSERT INTO Profiles_skills (ProfileID,
SkilCerts, NumYear, Lused)
VALUES ($LID, '$skill',
{$_SESSION['skys'][$key]},{$_SESSION['slus'][$key]})";
//$result = mysql_query($query);

Here is the problem:

Using
(((isset($_POST["skill[]"]))?$_POST["skill[]"]:"") .
"",true,true,true,true,"",false,1);

I can't seem to differentiate between the the elements
because they are all labeled skill[]
So basically validation isn't doing anything .

I'm thinking of finding a better way to validate , or
if i change the elements to skill[1], skill[2] , what
would that do to my iteration loop ?

Thank you,
Stuart
