getting a checkbox array value from POST

Question

i am posting an array of checkboxes. and i cant get it to work. i didnt include the proper syntax in the foreach loop to keep it simple. but it is working. i tested in by trying to do the same thing with a text field instead of a checkbox and it worked with the textfield.

<form method="post">
<?php 
foreach{
echo'
<input id="'.$userid.'" value="'.$userid.'"  name="invite[]" type="checkbox">
<input type="submit">';
}
?>
</form>

here is the part that is not working. it is echoing 'invite' instead of array.

<?php
    if(isset($_POST['invite'])){
$invite = $_POST['invite'];
echo $invite;
}

Answer 1

I just used the following code:

<form method="post">
    <input id="user1" value="user1"  name="invite[]" type="checkbox">
    <input id="user2" value="user2"  name="invite[]" type="checkbox">
    <input type="submit">
</form>

<?php
    if(isset($_POST['invite'])){
        $invite = $_POST['invite'];
        print_r($invite);
    }
?>

When I checked both boxes, the output was:

Array ( [0] => user1 [1] => user2 )

I know this doesn't directly answer your question, but it gives you a working example to reference and hopefully helps you solve the problem.
