Hooks and Filters

Hooks and filters are powerful PHP tools in WordPress that allow you to:

• Modify theme behavior without editing core files.
• Add custom features and functionalities to your site.

To add your first custom PHP snippet using hooks or filters, follow the steps below.

Step 1: Install the Child Theme

1. Navigate to Theme Options → System.
2. Click Install Child Theme if it's not already installed.

Note: A child theme is a minimal, standalone theme that inherits the design and functionality of the parent theme. It allows you to safely add custom PHP or CSS code without affecting the original (parent) theme. During theme updates, only the parent theme will be updated — your child theme and its custom code will remain intact and untouched.

Step 2: Edit the Functions File

1. Go to Appearance → Theme File Editor.
2. Select functions.php under the Child Theme section.
3. Add your PHP snippet at the end of the file.

}, 10);

Replace OPTION with the Theme Options settings you need to filter. Here are some examples:

• header_ctalink
• header_ctatext

Example code:

add_filter( 'uicore_get_option_header_ctalink', function($value){
   if(is_user_logged_in()){
         return 'https://my-domain.com/my-account';
   }
   return $value;
}, 10);
add_filter( 'uicore_get_option_header_ctatext', function($value){
   if(is_user_logged_in()){
         return 'My Account';
   }
   return $value;
}, 10);

2.21 uicore_global_upload_dir - change the upload folder of CSS and JS assets.

add_filter('uicore_global_upload_dir', function($upload_dir){
    // Customize the upload directory here if needed (eg find and replace /uploads/ with /assets/)
    $upload_dir['baseurl'] = str_replace('/uploads', '/assets', $upload_dir['baseurl']); //used in the frontend
    $upload_dir['basedir'] = str_replace('/uploads', '/assets', $upload_dir['basedir']); //used in the backend
    return $upload_dir;
});

Please make sure the new folder (ex: assets) already exists on your server inside the wp-content folder. To regenerate the assets on the new folder, go to Theme Options and Save.

2.22 uicore_pagetitle_title - generic page title filter

The example below removes the word "Category" from the portfolio archive page title:

add_filter('uicore_pagetitle_title', function ($title) {
            if(is_tax('portfolio_category')) {
                return single_term_title(null, false);
            }
            return $title;
        });

2.23 uicore_get_option_header_transparent - enable/disable transparent header

This is the core filter:

add_filter( 'uicore_get_option_header_transparent', function() {
            return 'false';
        } );

The example below disables the transparent header on blog posts:

add_action( 'wp', function() {
    if ( is_single() && get_post_type() === 'post' ) {
        add_filter( 'uicore_get_option_header_transparent', function() {
            return 'false';
        } );
    }
} );
