Shortcodes

What is shortcodeA magic word in post content that is replaced by some process defined in plugin or themes in runtime

Good for displaying complex dynamic contents

Shortcodes

Sample[gallery id=123 size=medium][gallery]

or

[caption]My Caption[caption] enclosed form

Shortcodes

add_shortcode()

$shortcode_tags = array()function add_shortcode($tag $func) global $shortcode_tags

if ( is_callable($func) ) $shortcode_tags[$tag] = $func

Shortcodes

function do_shortcode($content) global $shortcode_tags

if ( false === strpos( $content [ ) ) return $content

if (empty($shortcode_tags) || is_array($shortcode_tags)) return $content

$pattern = get_shortcode_regex() return preg_replace_callback( $patterns do_shortcode_tag $content )

Shortcodes

function do_shortcode_tag( $m )

if ( isset( $m[5] ) ) enclosing tag - extra parameter return $m[1] call_user_func( $shortcode_tags[$tag] $attr $m[5] $tag ) $m[6] else self-closing tag return $m[1] call_user_func( $shortcode_tags[$tag] $attr null $tag ) $m[6]

Shortcodes

callback params $attrs attributes $content enclosed tags text $tag shortcode tag itself

Admin-post

Data from clientsProcessing requests

You can just process requests in your own page because $_REQUEST $_GET $_POST is global

Admin-post

But in your own handlerYou cannot use WP core functionsYou cannot authenticate

Do not reinvent the wheelSo there is admin-postphp

Admin-post

wp-adminadmin-postphpdefine amp include minimal settingsand do_action

$action = empty( $_REQUEST[action] ) $_REQUEST[action]

admin_post_nopriv admin_post_nopriv_$actionadmin_post admin_post_$action

finish using die() in callback function

AJAX

Very similar to admin-post but DOING_AJAX is defineddefine( DOING_AJAX true )

also use die() in callback function

if ( is_user_logged_in() ) do_action( wp_ajax_ $_REQUEST[action] ) else do_action( wp_ajax_nopriv_ $_REQUEST[action] ) Default statusdie( 0 )

Redirect

You can generate custom page in plugin by using template_redirect action

function my_page_template_redirect() if( is_page( goodies ) ampamp is_user_logged_in() )

wp_redirect( home_url( signup ) ) exit()

add_action( template_redirect my_page_template_redirect )

Managing Your Own Contents

Wow there are too many things about posts

For today just focuse oncustom post type

Arguments are too complex

Just use Types or Pods pluginThats all problem solved

Yeah

of course you might not want this I was just kidding

Custom Post

You want to manage your own contentsThats why custom post is

Music collections Online store Event calendar Book data Photo portfolio

Custom Post Motivation

Well with just one type post and you may define many categories and use them to organize all contents

JUST ONE TYPE POSTMANY CATEGORIES

portfolio calendar music db

Custom Post Motivation

But you might feel that some post types should be hidden from some users even might be excluded from search may be only for private use may have very complex taxonomies
