php - Is there a simple way to ensure that fields within a contact form are present and/or valid (preferably present)?
I am a not very good with php forms and need help with the one I am working on. First and foremost I would like help with a simple way to ensure that all fields are present and valid. For the sake of space, I am using a form similar to this link http://distancebrothers.com/request-quote.html
The php code is listed below:
<?php . . . $name = $_POST['name']; $email = $_POST['email']; $phone = $_POST['phone']; $cmpny = $_POST['cmpny']; $street = $_POST['street']; $city_st_zip = $_POST['city_st_zip']; $respond = $_POST['respond']; $num_passengers = $_POST['num_passengers']; $trip_type = $_POST['trip_type']; $num_pickups = $_POST['num_pickups']; $bus_size = $_POST['bus_size']; $pickup_name = $_POST['pickup_name']; $pickup_street_name = $_POST['pickup_street_name']; $pickup_city_st_zip = $_POST['pickup_city_st_zip']; $depart_date = $_POST['depart_date']; $depart_time = $_POST['depart_time']; $dropoff_name = $_POST['dropoff_name']; $dropoff_street_name = $_POST['dropoff_street_name']; $dropoff_city_st_zip = $_POST['dropoff_city_st_zip']; $dropoff_date = $_POST['dropoff_date']; $dropoff_time = $_POST['dropoff_time']; $spec_instr = $_POST['spec_instr']; $meet_greet = $_POST['meet_greet']; $ada = $_POST['ada']; $extra = $_POST['extra']; $find_us = $_POST['find_us']; $formcontent="<html> <body><b>Contact Information:</b> <br><br>Name: $name <br>Email: $email <br>Phone: $phone <br>Company / Group Name: $cmpny <br>Street Name: $street <br>City, State, Zip Code: $city_st_zip <br>Respond Via: $respond <br><br><b>Event / Trip Details:</b> <br><br>Number of Passengers: $num_passengers <br>Trip Type: $trip_type <br>Number of Pickups: $num_pickups <br>Bus Size: $bus_size <br><br><b>Event / Trip Times - Departure and Destination:<br>Pick up location</b> <br><br>Name: $pickup_name <br>Street Name: $pickup_street_name <br>City, State, Zip Code: $pickup_city_st_zip <br>Depart Date: $depart_date <br>Depart Time: $depart_time <br><br><b>Drop Off Location</b><br><br>Name: $dropoff_name <br>Street Name: $dropoff_street_name <br>City, State, Zip Code: $dropoff_city_st_zip <br>Return Date: $dropoff_date <br>Return Time: $dropoff_time <br><br><b>Contact Information:</b> <br><br>Itinerary / Special Instructions / Additional Info:<br>$spec_instr <br>Airport Meet & Greet: $meet_greet <br>ADA Accessible Coach: $ada <br>Extra Storage: $extra <br>How did you find us? $find_us </body> </html>"; $recipient = "distancebrothers.com,[email protected]"; $subject = "Request for a Quote"; $mailheader = "From: $email \r\n"; $mailheader .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; mail($recipient, $subject, $formcontent, $mailheader) or die("Error!"); header( 'Location: http://www.distancebrothers.com/quote-confirmation.html') ;?>
You should probably trim the variables or white spaces, just in case a user tries to get around a required field. trim($value)
