trim function issues

Posted on 16th Feb 2014 07:03 pm by admin

Hi guys, total noob here...

So I've been tinkering around with a html and am using php to email the subitted data to me. It's all working fine, except now I've changed the rules of the form a little and I can't seem to make it do a very simple task of converting field data to a string so that I can have it in the body of the email.

Here's the code:

<?php

//If the form is submitted
if(isset($_POST['submit'])) {

//Check to make sure that the name field is not empty
if(trim($_POST['name']) == '') {
$hasError = true;
} else {
$name = trim($_POST['name']);
}

//Check to make sure sure that a valid email address is submitted
if(trim($_POST['email']) == '') {
$hasError = true;
} else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+.[A-Z]{2,4}$", trim($_POST['email']))) {
$hasError = true;
} else {
$email = trim($_POST['email']);
}

//If there is no error, send the email
if(!isset($hasError)) {
$emailTo = 'mickyginger@googlemail.com'; //Put your own email address here
$subject = 'Interest from the website';
$body = $name . $email;
$headers = 'From:' .$name. '<'.$email.'>' . "rn" . 'Reply-To: ' . $email;

mail($emailTo, $subject, $body, $headers);
$emailSent = true;
}
}
?>

Which works fine and dandy, only there are other fields like 'date' and 'venue' which I want to add to the body of the email regardless of whether they have been left blank or not.

Basically I want it to do something like this:

If the form is submitted

if name is not empty
$name = trim($_POST['name']);

if email is not empty
$email = trim($_POST['name']);

if number is empty OR if not
$number = trim($_POST['number']);

if date is empty OR if not
$date = trim($_POST['date']);

if there is no error
$body = $name . $email . $number . $date

seems like it should be really simple but I've tried everything I can think of with no joy...
