checkbox group form submission

[mark60480]

I'm trying to include a checkbox group in a form submission. The user can check one, two, or all three of the choices. I need only the checked boxes to appear in the e-mail to the admin. I understand I need to do some kind of an array, but don't know how. Here is the checkbox group code:

 

 

           

            <input type="checkbox" name="CheckboxGroup1[]" value="Choice1" id="1" />Select choice 1

            <input type="checkbox" name="CheckboxGroup1[]" value="Choice2" id="2" />Select choice 2

            <input type="checkbox" name="CheckboxGroup1[]" value="Choice3" id="3" />Select choice 3

 

And here is the line in the script:

 

            $mail_body .= "Choices: ".$_REQUEST['CheckboxGroup1'];

 

I will also attach the entire script.

 

Any help? THANKS!

CheckboxGroup1 will be posted as an array so you would need something like

 

 

$mail_body .= "Choices: ".join(', ', $_REQUEST['CheckboxGroup1']);

I think you want to use the foreach to loop through the values of CheckboxGroup1

 

 

$mail_body.= 'Choices: ';
$cbg1=$_REQUEST['CheckboxGroup1']; //just cause I don't like looping through a nested array
foreach ($cbg1 as $value){
$mail_body.=$value."  ";// spaces so the choices don't run together
}

You may also want to sanitize the input with htmlspecialchars() before you mail it to yourself.

Barand's solution is more elegant. I recreated a function that already exists.
