复选框在表单中发送多个选项

Question

Having an issue with receiving multiple options.

I have a form and I have just implemented a checkbox into my html:

<input type="checkbox" name="bookingoptions" value="1">  
<input type="checkbox" name="bookingoptions" value="2">          
<input type="checkbox" name="bookingoptions" value="3">

At the moment the form uses send_booking_email.php.

<form id="booking-form" form name="bookingform" method="post" action="send_booking_email.php">

Within send_booking_email.php:

<?php


if(isset($_POST['email'])) {


    $email_to = "[e-mail]";

    // validation expected data exists

    if(!isset($_POST['bookingoptions'])) {   

    }

    $bookingoptions = $_POST['bookingoptions']; // required

    $email_message .= "Booking Options:".clean_string($bookingoptions)."
";



// create email headers

$headers = 'From: '.$email_from."
".

'Reply-To: '.$email_from."
" .

'X-Mailer: PHP/' . phpversion();

@mail($email_to, $email_subject, $email_message, $headers);  

?>


<?php

}

?>

This works fine when one option is selected, however I am unable to get it to send multiple selections.

I believe it is due to:

$email_message .= "Booking Options:".clean_string($bookingoptions)."
";

Being only able to store one value? If so is there a way around this?

Thanks in advance!

Rename this field to bookingoptions[] and you will get array for $_POST['bookingoptions']

<input type="checkbox" name="bookingoptions[]" value="1">  
<input type="checkbox" name="bookingoptions[]" value="2">          
<input type="checkbox" name="bookingoptions[]" value="3">

then implode array elements into string:

clean_string(implode(', ', $bookingoptions))
