This question already has an answer here:
Okay, so I have a html form, and a using php for the server side validation to send the information from the form as an email. I cannot, for the life of me, get the form to send the items as an array.
Here's my html:
<select multiple name="symptoms[]">
<option value="ADHD">ADHD</option>
<option value="Insomnia">Insomnia</option>
<option value="Depression">Depression</option>
<option value="PTSD">PTSD</option>
<option value="Autism">Autism</option>
<option value="Stress">Stress</option>
<option value="Addiction">Addiction</option>
<option value="Pain">Pain/Headaches</option>
Here's my php in which I think the problem lies:
// validation expected data exists
if(!isset($_POST['first_name']) ||
!isset($_POST['last_name']) ||
!isset($_POST['email']) ||
!isset($_POST['telephone']) ||
!isset($_POST['symptoms']) ||
!isset($_POST['location']) ||
!isset($_POST['comment'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');
}
$first_name = $_POST['first_name']; // required
$last_name = $_POST['last_name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['telephone']; // not required
$symptoms = $_POST['symptoms']; // not required
$location = $_POST['location']; // not required
$comments = $_POST['comment']; // required
There is also this section of php, but I don't think the 'symptoms' area is a problem here...
function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);
}
$email_message .= "First Name: ".clean_string($first_name)."
";
$email_message .= "Last Name: ".clean_string($last_name)."
";
$email_message .= "Email: ".clean_string($email_from)."
";
$email_message .= "Telephone: ".clean_string($telephone)."
";
$email_message .= "Symptoms: ".clean_string($symptoms)."
";
$email_message .= "Location: ".clean_string($location)."
";
$email_message .= "Comment: ".clean_string($location)."
";
I have been trying to change the !isset all day and the $symptoms lines to get the 'symptoms' select multiple to show up on my email as an array. Right now it just says "array" in the email. I was thinking maybe the .clean-string should be something to do with array instead of string? I'm completely stuck, I've tried everything I can find, copied and pasted and tinkered and changed about 5 different sets of codes I found on stackoverflow...

If you echo (or concatenate, or some other method which will cast to string) an array, it will just say "Array", so you have to convert it to a string somehow. One method is to use implode, so you can display the array as a comma separated list:
$email_message .= "Symptoms: ".clean_string(implode(", ",$symptoms))."
";
if you want to get fancy and make sure there is an " and" before the last item, you could do
$symptomString = implode(", ", $symptoms);
$lastComma = strrpos($symptomString, ", ");
$symptomString = substr_replace($symptomString, "and", $lastComma, 2);
