Re: Regular Expressions

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.
