I am sorry, but your blog handles very bad meta characters and tags. i hope you can delete the posts and edit the code accordingly. It is pretty funny especially that you advise using htmlentities, but you’re not using it yourself, at least not here. :P

That $errors[] = $field; is better than array_push($errors, $field); is undoubtedly. You should change the script accordingly.
What I do not understand is why $temp = is_array($value) ? $value : trim($value); ? This really makes no sense at all. What it bothers me is that it makes no sense even if the posted value is indeed an array.

I understand that it’s beyond the purpose of this tutorial the problem of multiple selection as in the case of “checkboxes” or (some) “select” fields. For example this one:
I know PHP
I know JavaScript

Now if you want to use an array you can write something like this:

I know PHP
I know JavaScript

Now the fun begins as you may want to check both:
$_POST['programminglanguages'][0] and
$_POST['programminglanguages'][1].

At this point the $_POST['programminglanguages'] is indeed an array, but your code mentioned above makes no sense.

Nevertheless, a good starting point. Congrats.

OPS ! my code is gone :)
@Adham

Because you can, like this:

input name=”options[]” type=”text”

then when the form is submitted, $_POST['options'] will be already an array ;) . Let the fun begin
