if plugin is active? check if plugin is enabled or not?

2 Views

I’m using the mingle plugin and the mingle-forum plugin.

I want to show a certain part on my site only if those two plugins are active. How can I solve this?

<?php if ( is_plugin_active('mingle-forum') ) { ?>
                    <div id="login"><?php include (TEMPLATEPATH . '/inc/userlogin.php' ); ?></div>
                <?php } ?>

This throws a php error. Call to undefined function is_plugin_active

Any idea what I’m doing wrong?

update: 

<?php if ( plugin_active('plugin-directory/mingle-forum/wpf-main.php') ) { ?>
                    <div id="login"><?php include (TEMPLATEPATH . '/inc/userlogin.php' ); ?></div>
                <?php } ?>

  2. There are two way by which you can check plugin is active or not.

    1. You can use is_plugin_active function to check plugin active or
      not.

    2. If plugin have class then you can check like below-

      if (class_exists('YITH_Woocompare_Frontend')) 
{
echo 'your code';
}

    The above class related to YITH WooCommerce Compare plugin . The above code check if class exist then only you code inside the bracket will execute.

  3. You can also try to check plugin is Active or Not

    $pluginList = get_option( 'active_plugins' );
$plugin = 'PLUGIN_DIR/FILE_NAME.php'; 
if ( in_array( $plugin , $pluginList ) ) {
    // Plugin 'mg-post-contributors' is Active
}

    Also try below code for simplicity

    if ( is_plugin_active( 'PLUGIN_DIR/FILE_NAME.php' ) ) {
  //plugin is activated
}

  4. You can simply use the WordPress default function. This function exists in wp-admin/includes/plugin.php.

    Simply pass the Path to the plugin file relative to the plugins directory.

    $pluginPath = 'akismet/akismet.php';
if ( is_plugin_active( $pluginPath ) ) {
    echo 'Plugin is activated';
} else {
   echo 'Plugin is not activated';
}
