Wordpress Plugin Tools

The goal of this library is to simplify the proces of creating custom post types and settings pages in Wordpress.

Installation

You can install the package via composer:

composer require martijnvdb/wordpress-plugin-tools

Usage

All documented objects use a fluent interface, which allows you to chain methods. For example:

$custom_posttype = PostType::create('custom-posttype')
    ->setDescription('A very interesting description')
    ->setSlug('custom-slug')
    ->setIcon('dashicons-thumbs-up')
    ->setPublic()
    ->build();

Every chain should end with a build() method. The build() method will register the object using the Wordpress action hooks. Except when using an object as an argument in a method. In the following example, the CustomField object should not end with the build() method:

$custom_field = CustomField::create('custom-field')
    ->setType('textarea')
    ->setLabel('page-custom-textarea');

$custom_metabox = MetaBox::create('custom-metabox')
    ->addPostType('page')
    ->addCustomField($custom_field)
    ->build();

PostType

This object allows you to easily create one or multiple post types without having to worry about the Wordpress hooks. Chain any method you like and end with the build() method to register the post type.

Create a new PostType

$custom_posttype = PostType::create('custom-posttype')->build();

Add a MetaBox to the PostType

MetaBoxes on their own won't be shown anywhere. They have to be added to a PostType. These methods will do exactly that.

$first_metabox = MetaBox::create('first-metabox');
$second_metabox = MetaBox::create('second-metabox');
$third_metabox = MetaBox::create('third-metabox');

$custom_posttype = PostType::create('custom-posttype')
    ->addMetaBox($first_metabox) // Add a single MetaBox
    ->addMetaBoxes([$second_metabox, $third_metabox])// Or add multiple at once
    ->build();

Add labels to the PostType

All the Wordpress labels can be used. See a full list of supported labels.

$products_posttype = PostType::create('products')
    ->setLabel('name', 'Products') // Add a single label

    // Or add multiple at once
    ->setLabels([
        'singular_name' => 'Product',
        'add_new_item' => 'Add new Product',
        'add_new' => 'New Product',
        'edit_item' => 'Edit Product',
    ])
    ->build();

Add a description to the PostType

$custom_posttype = PostType::create('custom-posttype')
    ->setDescription('A very interesting description')
    ->build();

Make the PostType public

PostTypes are false by default. Using this method the PostType will be shown in the admin interface.

$custom_posttype = PostType::create('custom-posttype')
    ->setPublic()
    ->build();

Set menu position of the PostType

$custom_posttype = PostType::create('custom-posttype')
    ->setMenuPosition(8)
    ->build();

Set the icon of the PostType

$custom_posttype = PostType::create('custom-posttype')
    ->setIcon('dashicons-thumbs-up')
    ->build();

Add feature support to the PostType

Any Wordpress core feature can be used. The core features are title, editor, comments, revisions, trackbacks, author, excerpt, page-attributes, thumbnail, custom-fields and post-formats.

$custom_posttype = PostType::create('custom-posttype')
    ->addSupport(['title', 'thumbnail', 'comments']) // Must be an array
    ->build();

See a full list of supported features

Remove feature support from the PostType

Any Wordpress core feature can be removed. The core features are title, editor, comments, revisions, trackbacks, author, excerpt, page-attributes, thumbnail, custom-fields and post-formats.

$custom_posttype = PostType::create('custom-posttype')
    ->removeSupport(['editor']) // Must be an array
    ->build();

See a full list of supported features

Set the slug of the PostType

$custom_posttype = PostType::create('custom-posttype')
    ->setSlug('custom-slug')
    ->build();

Use the block editor in the PostType

$custom_posttype = PostType::create('custom-posttype')
    ->addBlockEditor()
    ->build();

Add any supported option to the PostType

This library only has a handfull of dedicated methods to set post type options. To use any other post type option you can use the addOption() method. See a full list of possible options.

$custom_posttype = PostType::create('custom-posttype')
    // Some examples
    ->addOption('show_in_admin_bar', false)
    ->addOption('show_in_nav_menus', false)
    ->addOption('has_archive', true)
    ->build();

CustomField

This object allows you to easily create one or multiple custom fields without having to worry about the Wordpress hooks. Chain any method you like and end with the build() method to register the custom field.

Create a new CustomField

$customfield = CustomField::create('new-customfield')->build();

Set the CustomField type

The possible CustomField types are text, textarea, checkbox, number, select, radio and editor.

$new_customfield = CustomField::create('new-customfield')
    ->setType('textarea')
    ->build();

Set the label of the CustomField

$new_customfield = CustomField::create('new-customfield')
    ->setLabel('New custom field')
    ->build();

Add options to the CustomField

This will only be used if the CustomField is a select or radio type.

$new_customfield = CustomField::create('new-customfield')
    ->setType('select') // Or 'radio'
    ->addOption('first-option', 'This is the first option')
    ->addOption('second-option', 'This is the second option')

    // Or add multiple at once
    ->addOptions([
        'third-option' => 'This is the third option',
        'fourth-option' => 'This is the fourth option'
    ]);
    ->build();

Set the minimal value of the CustomField

This will only be used if the CustomField is a number type.

$new_customfield = CustomField::create('new-customfield')
    ->setType('number')
    ->setMin(0)
    ->build();

Set the maximum value of the CustomField

This will only be used if the CustomField is a number type.

$new_customfield = CustomField::create('new-customfield')
    ->setType('number')
    ->setMax(100)
    ->build();

Set the size of the steps of the CustomField

This will only be used if the CustomField is a number type.

$new_customfield = CustomField::create('new-customfield')
    ->setType('number')
    ->setStep(10)
    ->build();

MetaBox

This object allows you to easily create one or multiple metaboxes without having to worry about the Wordpress hooks. Chain any method you like and end with the build() method to register the metabox.

Create a new MetaBox

$custom_metabox = MetaBox::create('custom-metabox')->build();

Set the title of the MetaBox

$custom_metabox = MetaBox::create('custom-metabox')
    ->setTitle('Metabox title')
    ->build();

Add a CustomField to a MetaBox

$first_customfield = CustomField::create('first-customfield');
$second_customfield = CustomField::create('second-customfield');
$third_customfield = CustomField::create('third-customfield');

$custom_metabox = MetaBox::create('custom-metabox')
    ->addCustomField($first_customfield)

    // Or add multiple at once
    ->addCustomFields([
        $second_customfield,
        $third_customfield,
    ])
    ->build();

Add a list to a MetaBox

This library allows you to easily create a growable and reorderable list of items. Each item in the list can contain multiple CustomFields. If for example you would like to add multiple URLs with a title and a description to a post, you can use a list for this.

$first_customfield = CustomField::create('first-customfield');
$second_customfield = CustomField::create('second-customfield');
$third_customfield = CustomField::create('third-customfield');

$custom_metabox = MetaBox::create('custom-metabox')
    ->addList('custom-list', [
        $first_customfield,
        $second_customfield,
        $third_customfield
    ])
    ->build();

Add the MetaBox to a Wordpress post type

The ID of the post types has to be used as an argument of these methods. These methods allow you to add MetaBoxes to existing post types which aren't created with this library.

$custom_metabox = MetaBox::create('custom-metabox')
    ->addPostType('page')

    // Or add multiple at once
    ->addPostTypes([
        'custom-posttype',
        'another-posttype',
    ])
    ->build();

Customize text

This library uses two text strings in the MetaBox which can be customized or translated. The following texts are used:

• new New
• delete_confirm Are you sure you want to delete this item?

This is how to customize them:

$custom_metabox = MetaBox::create('custom-metabox')
    ->setText('new', 'Nieuwe lijst')

    // Or customize multiple at once
    ->setTexts([
        'new' => 'Nieuwe lijst',
        'delete_confirm' => 'Weet u zeker dat u deze lijst wil verwijderen?'
    ])
    ->build();

SettingsPage

This object allows you to easily create one or multiple setting pages without having to worry about the Wordpress hooks. Chain any method you like and end with the build() method to register the setting page.

$custom_settingspage = SettingsPage::create('custom-settingspage')->build();

Set the page title of the SettingsPage

$custom_settingspage = SettingsPage::create('custom-settingspage')
    ->setPageTitle('The page title')
    ->build();

Set the menu title of the SettingsPage

$custom_settingspage = SettingsPage::create('custom-settingspage')
    ->setMenuTitle('Menu title')
    ->build();

Set the slug of the SettingsPage

$custom_settingspage = SettingsPage::create('custom-settingspage')
    ->setSlug('settingspage-slug')
    ->build();

Set the icon of the SettingsPage

$custom_settingspage = SettingsPage::create('custom-settingspage')
    ->setIcon('dashicons-thumbs-up')
    ->build();

Add CustomFields to the SettingsPage

$first_customfield = CustomField::create('first-customfield');
$second_customfield = CustomField::create('second-customfield');
$third_customfield = CustomField::create('third-customfield');

$custom_settingspage = SettingsPage::create('custom-settingspage')
    ->addCustomField($first_customfield)

    // Or add multiple at once
    ->addCustomFields([
        $second_customfield,
        $third_customfield,
    ])
    ->build();
