Reset Options Back to Default with update_option

Do you want to reset all WordPress settings back to default? While there’s probably a plugin for this, we have created a quick code snippet that you can use to reset options back to default with update_option in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

$options = array(
    array( 'name' => 'thumbnail_size_w', 'value' => '150' ),
    array( 'name' => 'thumbnail_size_h', 'value' => '150' ),
    array( 'name' => 'medium_size_w', 'value' => '250' ),
    array( 'name' => 'medium_size_h', 'value' => '250' ),
    array( 'name' => 'large_size_w', 'value' => '728' ),
    array( 'name' => 'large_size_h', 'value' => '728' ),
    array( 'name' => 'embed_size_w', 'value' => '728' ),
    array( 'name' => 'embed_size_h', 'value' => '600' ),
);

foreach ( $options as $option ) {
    if ( get_option( $option['name'] ) != $option['value'] ) {
        update_option( $option['name'], $option['value'] );
    } else {
        $deprecated = ' ';
        $autoload = 'no';
        add_option( $option['name'], $option['value'], $deprecated, $autoload );
    }
}
