806
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

$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, $mailheader) or die("Error!");
header( 'Location: http://www.distancebrothers.com/quote-confirmation.html')
;?>
Answer
Solution:
You should probably trim the variables or white spaces, just in case a user tries to get around a required field. trim($value)
