Examples

Display a list of registered importers

This example retrieves the registered importers list and displays each importer’s name and description.

$importers = get_importers();
if (!empty($importers)) {
    echo "<ul>";
    foreach ($importers as $importer_id => $importer_data) {
        echo "<li><strong>{$importer_data['name']}</strong>: {$importer_data['description']}</li>";
    }
    echo "</ul>";
} else {
    echo "No importers found.";
}

Check if a specific importer is registered

This example checks if a specific importer, such as the ‘rss’ importer, is registered on your site.

$importers = get_importers();
if (isset($importers['rss'])) {
    echo "RSS importer is registered.";
} else {
    echo "RSS importer is not registered.";
}

Run an importer if it is registered

This example checks if a specific importer, like the ‘wordpress’ importer, is registered, and runs the importer’s callback function if it exists.

$importers = get_importers();
if (isset($importers['wordpress'])) {
    call_user_func($importers['wordpress']['callback']);
} else {
    echo "WordPress importer is not registered.";
}

Register a new importer

This example registers a new custom importer called ‘my_custom_importer’ with a name, description, and callback function.

function my_custom_importer_callback() {
    // Your custom importer logic here
}

$importers = get_importers();
if (!isset($importers['my_custom_importer'])) {
    register_importer('my_custom_importer', 'My Custom Importer', 'A custom importer for my website', 'my_custom_importer_callback');
}

Unregister an importer

This example unregisters an existing importer, like the ‘wordpress’ importer, by removing it from the list of importers and updating the option in the database.

$importers = get_importers();
if (isset($importers['wordpress'])) {
    unset($importers['wordpress']);
    update_option('importers', $importers);
    echo "WordPress importer unregistered.";
} else {
    echo "WordPress importer is not registered.";
}
