using mail() function to submit form with checkboxes

[MeganMiller]

Hello.

I have an HTML form with checkboxes:

<input type="checkbox" name="vehicle" value="Accent" />Accent<br />
<input type="checkbox" name="vehicle" value="Elantra" />Elantra<br />
...

I want to send the information gathered from the form via the php mail() command, but have yet to figure out how to 'pull' the information from the checkboxes into a variable that I can then output in the email.

Here's what I have right now (It doesn't work!):

$vehicle = $_REQUEST['vehicle'];

(this is what I do for everything other than the checkboxes...)

and then:

$message .= "Vehicles: $vehicle";

What am I doing wrong? I am assuming that the values are stored as array; how can I access them?

THANK YOU very much for your help!

Do you want to allow multiple choices?

If so add brackets to the name:

<input type="checkbox" name="vehicle[]" value="Accent" />Accent<br />
<input type="checkbox" name="vehicle[]" value="Elantra" />Elantra<br />

And in that case:

$vehicle = implode(',',$_POST['vehicle']);

Also, depending on where in the email this data goes (body, header) and the content type, you might wanna validate it.

Thank you so much, it works great! I was so close with my other attempts, but didn't understand that I needed to use $_POST inside the implode() function. Can you tell me why POST instead of REQUEST?

$_POST has data sent to the server via HTTP POST, while $_REQUEST combines GET, POST and COOKIE data. It's a matter of good practice to take data from where you expect it to come, in this case POST.
