Did u try to print your POST array? <-- you should do that before asking for others to debug your script (ex. print_r($_POST)😉
First of all, did u write the HTML form?
Look of what u write here:
....
<input type="checkbox" name="new_quote[]" value="Yes">
....
<input type="checkbox" name="new_quote[]" value="No">
....
When u try to send the value in your email you write like this:
$new_quote = $_POST[new_quote];
Well this $_POST[new_quote] is an array and it look something like this:
[new_quote] => Array
(
[0] => Yes
[1] => No
)
Learn how to debug your script, dont come here and ask for others to do that for u, I just show u how to do, try and let me know how is going.
P.S. There is a saying: "Give a man a fish and you feed him for a day. Get a man to fish and you feed him for a life time."
P.S2. For the example I showed u above u use checkbox shouldnt u use radio button? because is either Yes or either No, it cant be both ...
