do you have a hand coded theme?
A while ago I did a theme for a friend and insted of any plugins, costum post types, etc. I created a page manually and made a sign up form. This is how my form was set up:
START OF PHP CODE!
$to = '[email protected]';
$subject="Your desired subject";
$option1= $_POST['option1'];
$option2= $_POST['option2'];
$option3= $_POST['option3'];
$body = <<< EMAIL
The desired message that will be sent to the given email.
Option 1: $option1
Option 2: $option2
Option 3: $option3
EMAIL;
$headers = “From: $email”;
if($_POST) {
mail($to, $subject, $body, $header);
}
END OF PHP CODE!
<label for="option1">Option 1</label> <br>
<input type="text" name="option1" id="option1" placeholder="Option 1" />
<label for="option2">Option 2</label> <br>
<input type="text" name="option2" id="option2" placeholder="Option 2" />
<label for="option3">Option 3</label> <br>
<input type="text" name="option2" id="option3" placeholder="Option 3" />
