Hi all, am trying to run a regular expression to a list of user entered data on some forms.

I've creating what i think is a matching pattern for each category as shown below:

function validateEntry($regularExpression, $fieldValue)
{
    if(preg_match($regularExpression, $fieldValue))
    {
        return "true";
    }
    else
    {
        return "false";
    }
}
is this all your function will ever do, or do you plan on extending it later?



i made a list of rules that are passed into the function above

1)  [a-zA-Z][0-9] //allow any characters and numbers together anywhere within the text
2)  [a-zA-Z]      //allow only any charaters in the text
3)  [0-9]{2}      //allow only digits and they must be 2 in length
4)  [a-zA-Z]{1}   //allow only 1 character either uppercase or lowercase

not sure how you are setting these up, but try something like this

$slpnum   = '!^[a-zA-Z0-9]+$!';
$slpha    = '!^[a-zA-Z]+$!';
$number   = '!^[0-9]{2}$!';
$aplshort = '!^[a-zA-Z]{1}$!';




but each of these fail the validation when data is entered appropriately , seems iam getting something wrong.
