How to make checkbox info append to email

I have 3 checkboxes on my contact form. The form works with exception to the checkboxes.. The boxes are selectable but once hitting the "submit" button the selection shows up on the "Thank you for you comment" page. I cannot figure out how to get the checkbox selection to appear in the actual email.

I have tried all sorts of php functions that I have found people to be using in forums and tutorials. Nothing appends the checkbox info to the email. I can't seem to find anyone who knows how to do this.

The 'implode' function does not work. The 'echo' function does not work. The 'array' function does not work. What could be going on?

Here is my html:

<section class="contact">  
    <form id="contact" action="html_form_send.php" method="post">
    <fieldset title="About you">
    <legend><span>About you</span></legend>
      <label for="name">Name</label>
      <input type="text" name="name" id="name" tabindex="10"  class="txtinput" placeholder="Your name" required>
      <label for="email">Email</label>
      <input type="email" name="email" id="email" tabindex="20" class="txtinput" placeholder="valid email" required>
    </fieldset>
    <fieldset title="Your turn">
    <legend><span>Your turn</span></legend>
<p>What, exactly then, are you after?</p>
<div>
<div class="tag">Checkbox1</div>        
        <input type="checkbox" id="checkbox-1-1" name="option[ ]" class="regular-checkbox big-checkbox" value="salvation" /></input><label for="checkbox-1-1"></label>
</div>
<div>
<div class="tag">Checkbox2</div>
<input type="checkbox" id="checkbox-2-1" name="option[ ]" class="regular-checkbox big-checkbox" value="question" /><label for="checkbox-2-1"></label>
</div>
<div>
<div class="tag">Checkbox3</div>
<input type="checkbox" id="checkbox-3-1" name="option[ ]" class="regular-checkbox big-checkbox" value="other" /><label for="checkbox-3-1"></label>
</div>
       <label for="comment" class="inline"></label>
          <label for="discourse">Write your comments here</label>
         <textarea id="discourse" name="discourse" tabindex="30" class="txtinput" rows="7" placeholder="This is where your thoughts go">
         </textarea>
        
    <section id="buttons">
    <input type="reset" name="reset" id="resetbtn" class="resetbtn" value="Reset">
    <input type="submit" name="submit" id="submitbtn" class="submitbtn" tabindex="40" value="Send away!">
    <br style="clear:both;">
</section>

Here is my php:

<?php

$_POST["option"] as $value) //Iterate the interest array and get the values
       
{
            echo 
$value//print the values
       
}
    }
}

The main two things I see...

First one, I'm not sure of, but I think there should be no spaces in the names for the options:

name="option[]" instead of name="option[ ]"

Once you have that setup, you will have an array of $_POST['option'] that will contain the values checked. If you don't check any checkboxes though, this will NOT exist at all.

So in your code you need to do if ( isset( $_POST['options'] ) ) { /* process the array */ }

I was a little bored while watching a movie, and threw this sample together for you. Note, this is designed to be a single file, form on same page that processes it, and submits to itself.

The big plus side to that is it will let you know errors on the form, and auto fill in (and check) what was already submitted instead of an unfriendly "Go Back and try again..." type of thing.

Also since field inputs get repeated (especially if you use this across several forms) I have text inputs and checkbox inputs set up as functions. As you will see, the HTML portion of the code is much cleaner this way.

PS. just noticed when I looked it over, there is a type on line 63, it should say None Selected instead of Non Selected
