Step#1: Using git
clone the latest CMB2 resources to your working project.
Step#2: Rename the CMB2-master
(or anything else) folder to cmb
.
Step#3: In your project’s functions.php
simply use the following code:
if( !class_exists("CMB2") ){
require_once( dirname(__FILE__)."/libs/cmb/init.php" );
}
(I put all my external libraries to /themes/my-theme/libs/
so I called it so)
Step#4: You can include the example-functions.php
from the cmb
folder to check whether it’s working or not. Simply use the following code in your functions.php
:
require_once ( get_template_directory() . '/libs/cmb/example-functions.php' );
if it works then you will see example meta boxes in Add New Page, because by default it’s coded like that: 'object_types' => array( 'page', ),
.
Alternatively
Step#1: Install the CMB2 plugin from the WordPress plugin repository
Step#2: Browse the wp-content/plugins/cmb2/
(I can’t remember the plugin folder name), and copy the example-functions.php
to your theme for testing.
Step#2: Simply use the following code in your functions.php
to add the file:
require_once ( get_template_directory() . '/example-functions.php' );
If it works in Add New Page, you can do your own job. 🙂
For your custom usage just copy the function (cmb2_sample_metaboxes()
) from the example and use the filter cmb2_meta_boxes
. You can follow the example-functions.php
completely. (In my installation it’s in line#36 – see here)
