One Click Demo Import

Description

The best feature of this plugin is, that theme authors can define import files in their themes and so all you (the user of the theme) have to do is click on the “Import Demo Data” button.

Are you a theme author?

Setup One Click Demo Imports for your theme and your users will thank you for it!

Follow this easy guide on how to setup this plugin for your themes!

Are you a theme user?

Contact the author of your theme and let them know about this plugin. Theme authors can make any theme compatible with this plugin in 15 minutes and make it much more user-friendly.

Where can I find the theme author contact?

Please take a look at our plugin documentation for more information on how to import your demo content.

This plugin is using the modified version of the improved WP import 2.0 that is still in development and can be found here: https://github.com/humanmade/WordPress-Importer.

NOTE: There is no setting to “connect” authors from the demo import file to the existing users in your WP site (like there is in the original WP Importer plugin). All demo content will be imported under the current user.

FAQ

I have activated the plugin. Where is the “Import Demo Data” page?

You will find the import page in wp-admin -> Appearance -> Import Demo Data.

Where are the demo import files and the log files saved?

The files used in the demo import will be saved to the default WordPress uploads directory. An example of that directory would be: ../wp-content/uploads/2023/03/.

The log file will also be registered in the wp-admin -> Media section, so you can access it easily.

How to predefine demo imports?

This question is for theme authors. To predefine demo imports, you just have to add the following code structure, with your own values to your theme (using the ocdi/import_files filter):

function ocdi_import_files() {
    return array(
        array(
            'import_file_name'           => 'Demo Import 1',
            'categories'                 => array( 'Category 1', 'Category 2' ),
            'import_file_url'            => 'http://www.your_domain.com/ocdi/demo-content.xml',
            'import_widget_file_url'     => 'http://www.your_domain.com/ocdi/widgets.json',
            'import_customizer_file_url' => 'http://www.your_domain.com/ocdi/customizer.dat',
            'import_redux'               => array(
                array(
                    'file_url'    => 'http://www.your_domain.com/ocdi/redux.json',
                    'option_name' => 'redux_option_name',
                ),
            ),
            'import_preview_image_url'   => 'http://www.your_domain.com/ocdi/preview_import_image1.jpg',
            'import_notice'              => __( 'After you import this demo, you will have to setup the slider separately.', 'your-textdomain' ),
            'preview_url'                => 'http://www.your_domain.com/my-demo-1',
        ),
        array(
            'import_file_name'           => 'Demo Import 2',
            'categories'                 => array( 'New category', 'Old category' ),
            'import_file_url'            => 'http://www.your_domain.com/ocdi/demo-content2.xml',
            'import_widget_file_url'     => 'http://www.your_domain.com/ocdi/widgets2.json',
            'import_customizer_file_url' => 'http://www.your_domain.com/ocdi/customizer2.dat',
            'import_redux'               => array(
                array(
                    'file_url'    => 'http://www.your_domain.com/ocdi/redux.json',
                    'option_name' => 'redux_option_name',
                ),
                array(
                    'file_url'    => 'http://www.your_domain.com/ocdi/redux2.json',
                    'option_name' => 'redux_option_name_2',
                ),
            ),
            'import_preview_image_url'   => 'http://www.your_domain.com/ocdi/preview_import_image2.jpg',
            'import_notice'              => __( 'A special note for this import.', 'your-textdomain' ),
            'preview_url'                => 'http://www.your_domain.com/my-demo-2',
        ),
    );
}
add_filter( 'ocdi/import_files', 'ocdi_import_files' );

You can set content import, widgets, customiser and Redux framework import files. You can also define a preview image, which will be used only when multiple demo imports are defined, so that the user will see the difference between imports. Categories can be assigned to each demo import, so that they can be filtered easily. The preview URL will display the “Preview” button in the predefined demo item, which will open this URL in a new tab and user can view how the demo site looks like.

How to automatically assign “Front page”, “Posts page” and menu locations after the importer is done?

You can do that, with the ocdi/after_import action hook. The code would look something like this:

function ocdi_after_import_setup() {
    // Assign menus to their locations.
    $main_menu = get_term_by( 'name', 'Main Menu', 'nav_menu' );

    set_theme_mod( 'nav_menu_locations', array(
            'main-menu' => $main_menu->term_id, // replace 'main-menu' here with the menu location identifier from register_nav_menu() function
        )
    );

    // Assign front page and posts page (blog page).
    $front_page_id = get_page_by_title( 'Home' );
    $blog_page_id  = get_page_by_title( 'Blog' );

    update_option( 'show_on_front', 'page' );
    update_option( 'page_on_front', $front_page_id->ID );
    update_option( 'page_for_posts', $blog_page_id->ID );

}
add_action( 'ocdi/after_import', 'ocdi_after_import_setup' );

What about using local import files (from theme folder)?

You have to use the same filter as in above example, but with a slightly different array keys: local_*. The values have to be absolute paths (not URLs) to your import files. To use local import files, that reside in your theme folder, please use the below code. Note: make sure your import files are readable!

function ocdi_import_files() {
    return array(
        array(
            'import_file_name'             => 'Demo Import 1',
            'categories'                   => array( 'Category 1', 'Category 2' ),
            'local_import_file'            => trailingslashit( get_template_directory() ) . 'ocdi/demo-content.xml',
            'local_import_widget_file'     => trailingslashit( get_template_directory() ) . 'ocdi/widgets.json',
            'local_import_customizer_file' => trailingslashit( get_template_directory() ) . 'ocdi/customizer.dat',
            'local_import_redux'           => array(
                array(
                    'file_path'   => trailingslashit( get_template_directory() ) . 'ocdi/redux.json',
                    'option_name' => 'redux_option_name',
                ),
            ),
            'import_preview_image_url'     => 'http://www.your_domain.com/ocdi/preview_import_image1.jpg',
            'import_notice'                => __( 'After you import this demo, you will have to setup the slider separately.', 'your-textdomain' ),
            'preview_url'                  => 'http://www.your_domain.com/my-demo-1',
        ),
        array(
            'import_file_name'             => 'Demo Import 2',
            'categories'                   => array( 'New category', 'Old category' ),
            'local_import_file'            => trailingslashit( get_template_directory() ) . 'ocdi/demo-content2.xml',
            'local_import_widget_file'     => trailingslashit( get_template_directory() ) . 'ocdi/widgets2.json',
            'local_import_customizer_file' => trailingslashit( get_template_directory() ) . 'ocdi/customizer2.dat',
            'local_import_redux'           => array(
                array(
                    'file_path'   => trailingslashit( get_template_directory() ) . 'ocdi/redux.json',
                    'option_name' => 'redux_option_name',
                ),
                array(
                    'file_path'   => trailingslashit( get_template_directory() ) . 'ocdi/redux2.json',
                    'option_name' => 'redux_option_name_2',
                ),
            ),
            'import_preview_image_url'     => 'http://www.your_domain.com/ocdi/preview_import_image2.jpg',
            'import_notice'                => __( 'A special note for this import.', 'your-textdomain' ),
            'preview_url'                  => 'http://www.your_domain.com/my-demo-2',
        ),
    );
}
add_filter( 'ocdi/import_files', 'ocdi_import_files' );

How to handle different “after import setups” depending on which predefined import was selected?

This question might be asked by a theme author wanting to implement different after import setups for multiple predefined demo imports. Lets say we have predefined two demo imports with the following names: ‘Demo Import 1’ and ‘Demo Import 2’, the code for after import setup would be (using the ocdi/after_import filter):

function ocdi_after_import( $selected_import ) {
    echo "This will be displayed on all after imports!";

    if ( 'Demo Import 1' === $selected_import['import_file_name'] ) {
        echo "This will be displayed only on after import if user selects Demo Import 1";

        // Set logo in customizer
        set_theme_mod( 'logo_img', get_template_directory_uri() . '/assets/images/logo1.png' );
    }
    elseif ( 'Demo Import 2' === $selected_import['import_file_name'] ) {
        echo "This will be displayed only on after import if user selects Demo Import 2";

        // Set logo in customizer
        set_theme_mod( 'logo_img', get_template_directory_uri() . '/assets/images/logo2.png' );
    }
}
add_action( 'ocdi/after_import', 'ocdi_after_import' );

Can I add some code before the widgets get imported?

Of course you can, use the ocdi/before_widgets_import action. You can also target different predefined demo imports like in the example above. Here is a simple example code of the ocdi/before_widgets_import action:

function ocdi_before_widgets_import( $selected_import ) {
    echo "Add your code here that will be executed before the widgets get imported!";
}
add_action( 'ocdi/before_widgets_import', 'ocdi_before_widgets_import' );

How can I import via the WP-CLI?

In the 2.4.0 version of this plugin we added two WP-CLI commands:

  • wp ocdi list – Which will list any predefined demo imports currently active theme might have,
  • wp ocdi import – which has a few options that you can use to import the things you want (content/widgets/customiser/predefined demos). Let’s look at these options below.

    wp ocdi import options:

    wp ocdi import [–content=] [–widgets=] [–customiser=] [–predefined=]

  • --content=<file> – will run the content import with the WP import file specified in the <file> parameter,

  • --widgets=<file> – will run the widgets import with the widgets import file specified in the <file> parameter,
  • --customiser=<file> – will run the customiser settings import with the customiser import file specified in the <file> parameter,
  • --predefined=<index> – will run the theme predefined import with the index of the predefined import in the <index> parameter (you can use the wp ocdi list command to check which index is used for each predefined demo import)

The content, widgets and customiser options can be mixed and used at the same time. If the predefined option is set, then it will ignore all other options and import the predefined demo data.

I’m a theme author and I want to change the plugin intro text, how can I do that?

You can change the plugin intro text by using the ocdi/plugin_intro_text filter:

function ocdi_plugin_intro_text( $default_text ) {
    $default_text .= '<div class="ocdi__intro-text">This is a custom text added to this plugin intro text.</div>';

    return $default_text;
}
add_filter( 'ocdi/plugin_intro_text', 'ocdi_plugin_intro_text' );

To add some text in a separate “box”, you should wrap your text in a div with a class of ‘ocdi__intro-text’, like in the code example above.

How to disable generation of smaller images (thumbnails) during the content import

This will greatly improve the time needed to import the content (images), but only the original sized images will be imported. You can disable it with a filter, so just add this code to your theme function.php file:

add_filter( 'ocdi/regenerate_thumbnails_in_content_import', '__return_false' );

How to change the location, title and other parameters of the plugin page?

As a theme author you do not like the location of the “Import Demo Data” plugin page in Appearance -> Import Demo Data? You can change that with the filter below. Apart from the location, you can also change the title or the page/menu and some other parameters as well.

function ocdi_plugin_page_setup( $default_settings ) {
    $default_settings['parent_slug'] = 'themes.php';
    $default_settings['page_title']  = esc_html__( 'One Click Demo Import' , 'one-click-demo-import' );
    $default_settings['menu_title']  = esc_html__( 'Import Demo Data' , 'one-click-demo-import' );
    $default_settings['capability']  = 'import';
    $default_settings['menu_slug']   = 'one-click-demo-import';

    return $default_settings;
}
add_filter( 'ocdi/plugin_page_setup', 'ocdi_plugin_page_setup' );

How to do something before the content import executes?

In version 2.0.0 there is a new action hook: ocdi/before_content_import, which will let you hook before the content import starts. An example of the code would look like this:

function ocdi_before_content_import( $selected_import ) {
    if ( 'Demo Import 1' === $selected_import['import_file_name'] ) {
        // Here you can do stuff for the "Demo Import 1" before the content import starts.
        echo "before import 1";
    }
    else {
        // Here you can do stuff for all other imports before the content import starts.
        echo "before import 2";
    }
}
add_action( 'ocdi/before_content_import', 'ocdi_before_content_import' );

How can I enable the `customise_save*` wp action hooks in the customiser import?

It’s easy, just add this to your theme:

add_action( 'ocdi/enable_wp_customize_save_hooks', '__return_true' );

This will enable the following WP hooks when importing the customiser data: customise_save, customise_save_*, customise_save_after.

How can I pass Amazon S3 presigned URL’s (temporary links) as external files ?

If you want to host your import content files on Amazon S3, but you want them to be publicly available, rather through an own API as presigned URL’s (which expires) you can use the filter ocdi/pre_download_import_files in which you can pass your own URL’s, for example:

add_filter( 'ocdi/pre_download_import_files', function( $import_file_info ){

    // In this example get_my_custom_urls` is supposedly making a `wp_remote_get` request, getting the urls from an API server where you're creating the presigned urls, [example here](https://docs.aws.amazon.com/sdk-for-php/v3/developer-guide/s3-presigned-url.html).
// This request should return an array containing all the 3 links - `import_file_url`, `import_widget_file_url`, `import_customizer_file_url`
$request = get_my_custom_urls( $import_file_info );

if ( !is_wp_error( $request ) )
{
    if ( isset($request['data']) && is_array($request['data']) )
    {
        if( isset($request['data']['import_file_url']) && $import_file_url = $request['data']['import_file_url'] ){
            $import_file_info['import_file_url'] = $import_file_url;
        }
        if( isset($request['data']['import_widget_file_url']) && $import_widget_file_url = $request['data']['import_widget_file_url'] ){
            $import_file_info['import_widget_file_url'] = $import_widget_file_url;
        }
        if( isset($request['data']['import_customizer_file_url']) && $import_customizer_file_url = $request['data']['import_customizer_file_url'] ){
            $import_file_info['import_customizer_file_url'] = $import_customizer_file_url;
        }
    }
}

return $import_file_info;

} );
`

I can’t activate the plugin, because of a fatal error, what can I do?

Update: since version 1.2.0, there is now a admin error notice, stating that the minimal PHP version required for this plugin is 5.3.2.

You want to activate the plugin, but this error shows up:

Plugin could not be activated because it triggered a fatal error

This happens, because your hosting server is using a very old version of PHP. This plugin requires PHP version of at least 5.3.x, but we recommend version 5.6.x or better yet 7.x. Please contact your hosting company and ask them to update the PHP version for your site.

Issues with the import, that we can’t fix in the plugin

Please visit this docs page, for more answers to issues with importing data.

Hey guys, just wanted to say thank you for the amazing plugin and recent update. I couldn't believe the features that you've added at first when I read change log. Few months ago I paid to a developer to add recommended plugins feature, and now I see it in your new update. For me as a theme developer this is a game-changer and the most important addon and it's just mind-blowing. P.S Haven't tested everything yet, going try it later 🙂
