Installation

  • Download or clone the repo
  • Include RationalOptionPages.php in your file
  • Instantiate the class with your array of pages
if ( !class_exists( 'RationalOptionPages' ) ) {
	require_once('RationalOptionPages.php');
}
$pages = array(
	'sample-page'	=> array(
		'page_title'	=> __( 'Sample Page', 'sample-domain' ),
	),
);
$option_page = new RationalOptionPages( $pages );

Note:

If you installed this previously and the class is already being instantiated somewhere else you will get fatal errors. You can avoid this by either renaming the class or by wrapping the require_once() in a if ( !class_exists() ) conditional.

Usage

Pages

Pages are added in a key/value syntax where the value is an array of parameters for the page itself.

Parameters

Based on WordPress' add_menu_page() function.

  • page_title - The text string for the title of the page Required.
  • menu_title - The text string for the menu item itself. Defaults to page_title.
  • capability - The permissions required to access this page. Defaults to manage_options.
  • menu_slug - The "slug" of the menu item. Defaults to a "slugified" version of the page_title.
  • icon_url - The URL of the menu icon. WordPress' Dashicons are available. Defaults to false, renders "dashicons-admin-generic".
  • position - The position where the menu item appears, from 1 to 99. Defaults to null, last.

If your page title is more than 2 words I recommend using the menu_title parameter to avoid wrapping. The default capability should work for most plugins and themes as only the admin would typically make higher level changes like these.

Subpages

Subpages are differentiated by the parent_slug parameter. They can be added either at the top level of the pages array submitted to the class or under a subpages key within another, top-level page parameter array.

Parameters

Based on WordPress' add_submenu_page() function.

  • parent_slug - The menu_slug of the parent page. WordPress has several top-level menu items. Required (unless added via the subpages key method).
  • page_title - The text string for the title of the page. Required.
  • menu_title - The text string for the menu item itself. Defaults to page_title.
  • capability - The permissions required to access this page. Defaults to manage_options.
  • menu_slug - The "slug" of the menu item. Defaults to a "slugified" version of the page_title.

Example

require_once('RationalOptionPages.php');
$pages = array(
	'sample-page'	=> array(
		'page_title'	=> __( 'Sample Page', 'sample-domain' ),
		// via the subpages key
		'subpages'		=> array(
			'sub-page-one'	=> array(
				'page_title'	=> __( 'Sub Page One', 'sample-domain' ),
			),
		),
	),
	// via the pages array itself
	'sub-page-two'	=> array(
		'parent_slug'	=> 'sample_page',
		'page_title'	=> __( 'Sub Page Two', 'sample-domain' ),
	),
	// sub page of the "Appearance" menu item
	'sub-theme'	=> array(
		'parent_slug'	=> 'themes.php',
		'page_title'	=> __( 'Sub Theme', 'sample-domain' ),
	),
);
$option_page = new RationalOptionPages( $pages );

Sections

Sections are added via a sections key in the page parameter arrays.

Parameters

Based on WordPress' add_settings_section() function.

  • title - The title of the section. Required.
  • id - The ID of the section.
  • callback - An optional parameter for generating custom, section content. Requires custom parameter be set to true.
  • custom - A boolean option that indicates you want to use a custom callback. Defaults to false.
  • text - An option parameter for adding HTML text under the section title.
  • include - An option parameter that calls PHP's include() under the section title. Use absolute path.

Example

require_once('RationalOptionPages.php');
$pages = array(
	'sample-page'	=> array(
		'page_title'	=> __( 'Sample Page', 'sample-domain' ),
		'sections'		=> array(
			'section-one'	=> array(
				'title'			=> __( 'Section One', 'sample-domain' ),
				'text'			=> '<p>' . __( 'Some HTML text to describe the section', 'sample-domain' ) . '</p>',
				'include'		=> plugin_dir_path( __FILE__ ) . '/your-include.php',
			),
			'section-two'	=> array(
				'title'			=> __( 'Section Two', 'sample-domain' ),
				'custom'		=> true,
				'callback'		=> 'custom_section_callback_function',
			),
		),
	),
);
$option_page = new RationalOptionPages( $pages );

Fields

Fields are added via a fields key in the section parameter array.

Parameters

Based on WordPress' add_settings_field() function.

  • title - The title/label of the field. Required.
  • id - The ID of the field.
  • callback - An optional parameter for generating custom, field content. Requires custom parameter be set to true.
  • custom - A boolean option that indicates you want to use a custom callback. Defaults to false.

  • title_attr - The "title" attribute of the input (if available).
  • choices - Associative array of options for radio groups and select elements. Required for radio and select types.

  • value - The default value of the input.
  • checked - A boolean for the default state of the checkbox type. Defaults to false.
  • attributes - Associative array of additional attributes for the input element.
    • Input - autocomplete, autofocus, disabled, list, max, maxlength, min, pattern, readonly, required, size and step
    • Select - multiple, size
    • Textarea - cols, rows and wrap
  • sanitize - A boolean that indicates whether or not the field's value should be sanitized. Defaults to false, and doesn't apply to checkboxes.

Examples

The most basic of inputs.

require_once('RationalOptionPages.php');
$pages = array(
	'sample-page'	=> array(

);
$option_page = new RationalOptionPages( $pages );

Retrieving Data

Each page stores it's fields in an entry in the database. The key is the array key for your page.

Using the example above as a reference:

// Get all options for the page
$options = get_option( 'sample-page', array() );

// Each field id is a key in the options array
$date = $options['date'];
$tel = $options['telephone'];

If you let the class generate the field IDs then they will be "slugified" versions of the title parameter. For example; a field with the title of "Website Address" will have an ID of "website_address". You can also see this key by inspecting the input and looking at the input's name attribute. Within the square ([]) brackets.

To Do

  • Add text and include parameters to pages.
