How to check if woocommerce is activated in theme

Question

I'm creating a theme with woocommerce which has the following:

<ul>

  <li>
    <?php 
    if( is_user_logged_in() ){ 
    ?>
      <a href="<?php echo get_permalink( get_option( 'woocommerce_myaccount_page_id' ) ); ?>" title="<?php _e( 'My Account', 'woothemes' ); ?>"><?php _e( 'My Account', 'woothemes' ); ?></a>
    <?php } else { ?>
      <a href="<?php echo get_permalink( get_option( 'woocommerce_myaccount_page_id' ) ); ?>" title="<?php _e( 'Sign-in', 'woothemes' ); ?>"><?php _e( 'Sign-in', 'woothemes' ); ?></a>
    <?php 
    } 
    ?>
  </li>

  <li>
    <a href="<?php echo get_option( 'home' ) . '/' . 'my-lists/' ?>" title="My Wishlist">Wishlist</a>
  </li>

  <!--
  <li><a href="#" title="Email updates">Email Updates</a></li>
  -->
  <li> 
    <?php 
    global $woocommerce; 
    ?>
    <a id="header-ShoppingCart" class="cart-contents" href="<?php echo $woocommerce->cart->get_cart_url(); ?>" title="<?php _e( 'View your shopping cart', 'woothemes' ); ?>"><?php echo sprintf( _n( '%d item', 'My Bag (%d)', $woocommerce->cart->cart_contents_count, 'woothemes' ), $woocommerce->cart->cart_contents_count ); ?> - <span id="header-cartCount"><?php echo $woocommerce->cart->get_cart_total(); ?></span></a>
  </li>

</ul>

However this breaks the site if the woocommerce plugin is not activated. How can I check if the woocommerce plugin is activated?

Answer 1

You could check to see if the 'WooCommerce' class exists, then run the code that requires WooCommerce.

<?php
if ( class_exists( 'WooCommerce' ) ) {
  // code that requires WooCommerce
} else {
  // you don't appear to have WooCommerce activated
}
?>

Answer 2

To check if woocommerce or anyother plguin is active, paste the following code on the template where you want to display the message.

if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
    echo 'WooCommerce is active.';
} else {
    echo 'WooCommerce is not Active.';
}

Answer 3

Use following code. It will work on multi site also.

include_once( ABSPATH . 'wp-admin/includes/plugin.php' );
if ( is_plugin_active( 'woocommerce/woocommerce.php') ) {
  // Do what you want in case woocommerce is installed
}

Answer 4

I would perform the class check once all plugins are loaded. Because in some cases it can return false negative.

add_action( 'plugins_loaded', 'see_all_plugins_loaded' );

function see_all_plugins_loaded() {
   if ( class_exists( 'WooCommerce' ) ) {
       // do your stuff
   }
 }

Answer 5

The new official way to do it with multisite support:

// Test to see if WooCommerce is active (including network activated).
$plugin_path = trailingslashit( WP_PLUGIN_DIR ) . 'woocommerce/woocommerce.php';

if (
    in_array( $plugin_path, wp_get_active_and_valid_plugins() )
    || in_array( $plugin_path, wp_get_active_network_plugins() )
) {
    // Custom code here. WooCommerce is active, however it has not 
    // necessarily initialized (when that is important, consider
    // using the `woocommerce_init` action).
}

Answer 6

I use:

$is_woo = (function_exist('is_woocommerce') || class_exists( 'WooCommerce' ) );
if($is_woo){
    // WooCommerce Is Active
}else{
    // WooCommerce Isn't Active
}

you can use this easy method too:

function kdev_is_active_woocommerce(){
    return  (function_exists('is_woocommerce') || class_exists( 'WooCommerce' ) ) || ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) );
}
if(kdev_is_active_woocommerce()){
    // WooCommerce Is Active
}else{
    // WooCommerce Isn't Active
}
