Problem HTML_QuickForms processing select array

[petemcw]

So I have a page created with HTML_QuickForms.
I have it pumping out a <select> menu with info from my database. The select menu also has the "multiple" option set.

So what I want to do is simply process that select menu. It instead of the expected array of selected options, the variable is returning as "string[5] Array". It is returning the actual word "Array".

I can't figure this out. I have other forms on other sites where this works fine, but the form is just hard coded. For whatever reason, I think the HTML_QuickForm is screwing it all up.

Here is part of the code...

// Instantiate the QuickForm Class
    $form = new HTML_QuickForm('submitForm1', 'POST');
    
    // The headline field
    $form->addElement('text', 'headline', 'Headline: ', 'size="40"');
    $form->addRule('headline', 'Please enter a headline', 'required', false);
    $form->addRule('headline', 'Headlines cannot be more than 100 characters', 'maxlength', 100);

    // The category field
    $select =& $form->createElement('select','category','Category: ');
    $select->loadArray($categories);
    $select->setMultiple(true);
    $form->addElement($select);

    // Add Submit Button
    $form->addElement('submit', 'submit', 'Go to Step 2'); 

That creates the form properly like:
<select name="category[]" multiple>....

This is how I think I am suppose to process the form, it works fine for any text field, textarea, checkbox, etc.

// If the form is submitted ...
    if ($form->validate())
    {
        // Apply the escape filter to all fields
        $form->applyFilter('__ALL__', 'escapeValue');
        
        $headline = $form->getSubmitValue('headline');
        $category = $form->getSubmitValue('category');
                
        header('Location: release_step2.php');
    } 

I have tried numerous other ways of getting the data, such as $_POST['category'], etc. but it always seems to come back as a string with the value "Array".

Anybody out there run into this before, or know how to get this going???
Thanks!!!

Everything looks perfect with the code. There's nothing wrong.
Could you paste here the value of $categories that you pass here:

$select->loadArray($categories); 

It should be OK if it's something like:

$categories = array ('value1' => 'option1', 'value2' => 'option2');

Hey, yeah this is pretty weird, huh.
The code for the categories is:

// Get Categories
    $sql = 'SELECT * FROM _categories ORDER BY id ASC';
    $results = $db->query($sql);
    if (!$results->isError())
    {
        while ($row = $results->fetch())
        {
            $categories[$row['id']] = $row['category_name'];
        }
    } 

This gives me a value/name pair basically and loads up the menu great!
I just can't get the selected values after the form is posted.

I am even having trouble with HTML_QuickForm's own date psuedo-element. I can get the elements to display properly, but again, I can't get the values after post...just a string value of "Array".
