send checkbox value in PHP form

Question

I have a question regarding a php form. I\'ve added a checkbox to the existing form, but not sure how to add it to the php. I would like it to send \"yes\" if the visitores

Answer 1

If the checkbox is checked you will get a value for it in your $_POST array. If it isn't the element will be omitted from the array altogether.

The easiest way to test it is like this:

if (isset($_POST['myCheckbox'])) {
  $checkBoxValue = "yes";
} else {
  $checkBoxValue = "no";
}

For your code, add it immediately below the other preprocessing:

$name = $_POST['name']; 
$email_address = $_POST['email']; 
$message = $_POST['tel']; 

if (isset($_POST['newsletter'])) {
  $newsletter = "yes";
} else {
  $newsletter = "no";
}

You'll also need to change the HTML slightly. Change this line:

i want to sign up for newsletter

to this:

i want to sign up   for newsletter
