How do you modify the value of existing preset in Beaver Builder Theme? You are activating the BB child theme and default value of a preset is modifying automatically without open the theme customizer. In this article I am showing how you will do this via PHP.

Assuming that you will modify the default value of “Default Dark” preset.

Step 1

Creating the new PHP file “class-customizer-defaults.php” and putting into bb child theme’s classes folder. Now open the file and add the following PHP snippet:

Setting Default Values

 'default-dark',
			'fl-layout-width' 					=> 'full-width',
			'fl-content-width' 					=> '1170',
			'fl-body-bg-color' 					=> '#ffffff',
			'fl-scroll-to-top' 					=> 'enable',
			'fl-accent' 						=> '#13afdf',
			'fl-accent-hover' 					=> '#2e2f33',
			/* Heading */
			'fl-heading-text-color' 			=> '#2e2f33',
			'fl-heading-font-family' 			=> 'Libre Franklin',
			'fl-heading-font-weight' 			=> '300',
			'fl-h1-font-size' 					=> '26',
			'fl-h2-font-size' 					=> '24',
			'fl-h3-font-size' 					=> '20',
			'fl-h4-font-size' 					=> '18', 
			'fl-h5-font-size' 					=> '16', 
			'fl-h6-font-size' 					=> '15', 
			/* Body */
			'fl-body-font-family' 				=> 'Libre Franklin',
			'fl-body-text-color' 				=> '#333333',
			'fl-body-font-weight' 				=> '400',
			'fl-body-font-size' 				=> '16',
			'fl-body-line-height' 				=> '1.66',
			/* Top bar */
			'fl-topbar-text-color' 				=> '#2e2f33',
			'fl-topbar-link-color' 				=> '#2e2f33',
			'fl-topbar-hover-color' 			=> '#13afdf',
			'fl-header-padding' 				=> '0',
			'fl-fixed-header' 					=> 'fixed',
			'fl-header-text-color' 				=> '#333333',
			'fl-header-link-color' 				=> '#2e2f33',
			'fl-header-hover-color' 			=> '#13afdf',
			/* Footer */
			'fl-footer-widgets-link-color' 		=> '#2e2f33',
			'fl-footer-widgets-hover-color' 	=> '#13afdf',
			'fl-footer-link-color' 				=> '#2e2f33',
			'fl-footer-hover-color' 			=> '#13afdf',
			/* Logo */
			'fl-logo-font-family' 				=> 'Libre Franklin',
			'fl-logo-font-weight' 				=> '800',
			'fl-logo-font-size' 				=> '35',
			'fl-nav-font-family' 				=> 'Libre Franklin',
			'fl-nav-link-color' 				=> '#2e2f33',
			'fl-nav-hover-color' 				=> '#13afdf',
			'fl-nav-item-spacing' 				=> '10'
		);

		add_filter( 'fl_default_theme_mods', __CLASS__ . '::probb_theme_default_mods' );

		// Setup the Theme Customizer settings and controls...
		add_action( 'customize_register' , __CLASS__ . '::register', 12 );
	}

	static public function probb_theme_default_mods( $mods )
	{
		$mods = wp_parse_args( self::$default_args, $mods );

		return $mods;
	}

	static public function register( $wp_customize )
	{
		foreach (self::$default_args as $key => $value) {
			$wp_customize->get_setting( $key )->default = $value;
		}
	}
}

CustomizerDefaultMods::init();

Step 2:

Open the functions.php of BB child theme and add the following PHP code below this line require_once ‘classes/class-fl-child-theme.php’;

Include the PHP file

require_once 'classes/class-customizer-defaults.php';

Now navigate to Dashboard->Appearance->Themes page and activate the BB child theme. Default value of “Default Dark” preset will overwrite with yours one automatically.
