Subject: php Form Validation help have a form that I would like to validate before it is submitted to the DB. I am having trouble with a couple of sections. I have a select box with a listing of all the states, the first option is "Choose One" with a value of "0". Would this be the correct way to "validate" this field?

if ($_POST["state"]==0) {

//      Display error message that no state is selected
        print '<p>Please select your State</p>';

}

Second, another part of the same form I have fields for phone numbers, once the field is submitted I would like to join the 3 sections of areacode, nxx and prefix. I have done this to join them, is this correct?

Almost there : Put quotes around parts of your output that aren't variables (ie quote literal text strings) $phone = $_POST['p-areacode'] . "-" . $_POST['p-prefix']. "-" .$_POST['p-suffix'];

The next question id for both phone number and area code. If I want to validate the zip code and ensure a minimum of X characters in the field, numbers only how would I do this?

if (strlen($zip_str) < 5) {

        print '<p>Please enter your Zip Code (EX. 77662)</p>';
