基于表单的自定义主题行

Question

I have a form with multiple check boxes. once the form is complete it is sending a email with php. I'm trying to have a feature in the subject bar so it displays

Subject: Option 1

Subject: Option 2

Subject: Option 1 and Option 2

if (empty($_POST["CheckboxGroup1"]) || empty($_POST["CheckboxGroup2"])) { 
"$displaythis = '';"; }
else { "$displaythis = ' and ';"; }

Something is wrong but I don't know where. Any tips? Thanks

$emailSubject = $_POST['CheckboxGroup1'] . $displaythis . $_POST['CheckboxGroup2'];

Remove the double quotes:

if (empty($_POST["CheckboxGroup1"]) || empty($_POST["CheckboxGroup2"])) { $displaythis = ''; }
else { $displaythis = ' and '; }
