PHPMailer required fields

Hello all,

I am very new to PHP and have a question about making fields in my html form required using a PHPMailer script. The current script that I am using that works is:

<?php
error_reporting(E_ALL);
include_once('class.phpmailer.php');

$mail = new PHPMailer();
$mail->IsSMTP();
//$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Host = "bluestar4.ukhost4u.com"; // sets the SMTP server
$mail->Port = 25; // set the SMTP port for the GMAIL server
$mail->Username = "test@email.com"; // SMTP account username
$mail->Password = "monkey"; // SMTP account password

$mail->From = "test@email.com";
$mail->FromName = "UK Website";
$mail->Subject = "UK Contact Form Submission";

$mail->AddAddress("tim@email.com", "Tim");

$message = "Message from UK Contact Form<br><hr>";

foreach ($_POST as $key => $value) {
$message .= "<br>".$key.": ".$value;
}
$mail->MsgHTML($message);

if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
header("Status: 200");
header("Location: /thankyou-contact.htm");
}
?>


Can anyone assist me with how I would make some fields required on my website form?

Thanks a million in advance!

 

Here is an easy way to do this.

Lets say you have an email, name, and phone field.

$requiredArr = array('email','name','phone');

		foreach($_POST as $key => $value){
			if(in_array($key,$requiredArr) && empty($value)){
				$errorArr[] = 'Missing value for '.$key;
			}
		}
		
		if(count($errorArr) > 0){
			// error stuff
		}
		else{
			// send an email
		}

Code (markup):

 

Do I just add this to the end of my code? What do I put for //error stuff and //send as email?

 

Yes.

For the //error stuff you can print the error message to the screen:
echo "Missing a required value"; // or do a for loop and print every missing element in the $errorArr
// or print the error as a comment for your own debuggin: echo("<!-- $errorArr --->");

For the //send email:

just include the logic you already have
