Post Type Class

This class allows you to build WordPress Custom Post Types (CPT's) in as little as 2 lines of code! The class features the following:

• Create CPT's
• Create and populate meta boxes
• Easy debugging
• Automatic Nonce security

---

Creating a New CPT

$obj = new PostType($cptName, $cptArgs);
$obj->create();

$cptName (STRING) The CPT slug.
$cptArgs (Array) CPT arguments as defined by register_post_type()

NOTE: Once you call the create() method, the $obj gets destroyed. This is to prevent any further manipulation of the object, which could create duplicate CPT's.

---

Input:

$homeSlideshow = new PostType(
    'home-slideshow',
    array(
        'label'        => 'Home Slideshow',
        'public'       => true,
        'show_in_menu' => 25,
        'supports'     => array('title', 'editor', 'thumbnail')
    )
)

---

Output: Creates a custom post type named home-slideshow and positions it's menu underneath Comments. It is now fully functional and allows you to edit its Title, content, and thumbnail!

---

Adding Meta Boxes

$obj->meta_box(array($metaLabel, $metaForm));

$metaLabel (STRING) Meta box label. May include basic HTML styling tags.
$metaForm (ARRAY) Setup as follows

array(
    'label'     => STRING,
    'meta'      => STRING,
    ['type'     => STRING = "text",]
    ['caption'  => STRING,]
    ['attribtues' => STRING]
)

label Label text. The for attribute and input id is sanitize_title( label )
meta The key used in get_post_meta().
type The input type. ( DEFAULT = "text" )
caption The input caption, which is displayed underneath the input box.
attribtues Allows you to set a list of additional attributes. It must be a single string, and must only use quotes! ex)

'attributes' => 'min="0" max="100" style="background: red;"'

---

When the add_meta_box call is defined, its arguments are generated as follows:

$id         = sanitize_title( $obj->cptArgs->label );
$title      = $metaLabel
$callback   = $this->meta_box_cb (a unique closure)
$post_type  = $obj->cptName
$context    = DEFAULT
$priority   = DEFAULT
$callback_args = NONE, the closure automatically pulls arguments

---

Input:

$homeSlideshow->metabox(
    'Home Slideshow Properties',
    array(
        array(
            'label'     => 'Read More: ',
            'meta'      => '_slideReadMore',
            'caption'   => 'text for the read more button'
        ),
        array(
            'label'     => 'Slide Links To: ',
            'meta'      => '_slideURL'
        ),
        array(
            'label'     => 'Extra text',
            'meta'      => '_slideExtra',
            'type'      => 'textarea'
        )
    )
)

---

Output: Creates a meta box labeled "Home Slide Properties", with three sets of labels ("Read More" (with caption), "Slide Links To", and a textarea labeled "Extra Text") and 2 text input boxes plus 1 textarea (#slide-read-more, #slide-links-to, #slide-extra-text).

---

Options

Below are a list of additional options you can set and their default values:

$obj->nonce->name    = $this->cptName . '_nonce';
$obj->nonce->action  = $this->cptName . '_action';

$obj->cap            = 'edit_page';

$obj->nonce->name and obj->nonce->action correspond to the $name and $action arguments in wp_nonce_field which is checked on save. Change these if you'd you need to.

$obj->cap is used to set the capability requirements for saving the page, which defaults to 'edit_page'. If your CPT requires admin acces simply do something as follows:

$homeSlideshow->cap = 'manage_options';

---

TO DO

2. Add aliases for function names. Ex) $obj->meta_box() === $obj->mb()
3. Define basic HTML tags for $obj->meta_box()
4. Add default values for input fields
5. Turn off debugging for optimization
6. Add support for textareas and other non INPUT elements
7. Allow for get_post_type array
8. Allow for styling
9. Set multiple default CPT settings
