Another option that exists for integrating the Primary Category in to the WooCommerce breadcrumbs is to simply override the main term that WooCommerce uses to generate the crumbs. The code below demonstrates how to do this using the `woocommerce_breadcrumb_main_term` filter. This code can be added to your theme’s functions.php file or in a plugin file:

The filter that is used for this example is ‘wysiwyg_tinymce_settings‘. This filter makes it possible to edit the TinyMCE  settings immediately before the field is initialized. What I decided to do was to make use of the existing CSS wrapper field in the ACF admin:

Then, using the previously mentioned filter, I grab those values and apply them to the WYSIWYG editor’s iframe body tag:

Now, if I specify the correct class names within my ‘editor-styles.css’ file, the editor will get the custom styling I’ve set.

Now I can easily style all the ACF WYSIWYG fields in my admin so that they exactly reflect how the content will look on the front end.

The full code is available on Github.

Step 1 – Install WP-CLI

curl -L https://github.com/wp-cli/wp-cli/releases/download/v0.13.0/wp-cli.phar > wp-cli.phar

And then running these commands in order to be able to call WP-CLI by just using ‘wp’:

chmod +x wp-cli.phar
sudo mv wp-cli.phar /usr/bin/wp

Step 2 – Configure WP-CLI to use AMPPS binaries

At this point, if you’re using AMPPS to serve web sites locally, you’ll notice that any call to ‘wp’ within a site directory will return the “Error Establishing A Database Connection” message.  This is due to WP-CLI using the bundled PHP binary which is separate from the binary you are using for AMPPS.  The way to fix this is by adding some values to your bash_profile file.  To open the .bash_profile file, run this command:

open ~/.bash_profile

This should launch TextEdit window for editing your .bash_profile file. Add this line (modify the path to AMPPS to match your directory configuration) and save the file:

export PATH="/Applications/AMPPS/php/bin:/Applications/AMPPS/mysql/bin:$PATH"

Now you will need to restart Terminal in order for the updates to be applied. Verify the new path has been set by using this command:

wp --info

The PHP binary setting should now be pointing to the PHP binary within your AMPPS directory. If not, go back and verify that the paths you entered in the .bash_profile file are correct.

• pass in a default value in case none are found
• fall back to site options (if one exists)
• pass in the ID of the post to get the field from and then apply the previous actions

function display_admin_bar_template() {
   global $wp_admin_bar;
   $wp_admin_bar->add_node( array(
      'id' => 'templateMethod',
      'title' => __( 'Template: ', 'hwid' ) . str_replace( get_theme_root(), '', get_page_template() )
   ));
}
add_action( 'wp_before_admin_bar_render', 'display_admin_bar_template' );
