Theme Demo Import

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

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/2016/03/. The log file will also be registered in the wp-admin -> Media section, so you can access it easily.

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 theme-demo-import/import_files filter): function TDI_import_files() { return array( array( 'import_file_name' => 'Demo Import 1', 'import_file_url' => 'http://www.your_domain.com/tdi/demo-content.xml', 'import_widget_file_url' => 'http://www.your_domain.com/tdi/widgets.json', 'import_customizer_file_url' => 'http://www.your_domain.com/tdi/customizer.dat', 'import_preview_image_url' => 'http://www.your_domain.com/tdi/preview_import_image1.jpg', 'import_notice' => __( 'After you import this demo, you will have to setup the slider separately.', 'your-textdomain' ), ), array( 'import_file_name' => 'Demo Import 2', 'import_file_url' => 'http://www.your_domain.com/tdi/demo-content2.xml', 'import_widget_file_url' => 'http://www.your_domain.com/tdi/widgets2.json', 'import_customizer_file_url' => 'http://www.your_domain.com/tdi/customizer2.dat', 'import_preview_image_url' => 'http://www.your_domain.com/tdi/preview_import_image2.jpg', 'import_notice' => __( 'A special note for this import.', 'your-textdomain' ), ), ); } add_filter( 'theme-demo-import/import_files', 'TDI_import_files' ); You can set content import, widgets, and customizer 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.

You can do that, with the theme-demo-import/after_import action hook. The code would look something like this: ` function TDI_after_import_setup() { // Assign menus to their locations. $main_menu = get_term_by( 'name', 'Top Menu', 'nav_menu' ); set_theme_mod( 'nav_menu_locations', array( 'primary-menu' => $main_menu->term_id, ) ); // 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( 'theme-demo-import/after_import', 'TDI_after_import_setup' ); `

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 TDI_import_files() { return array( array( 'import_file_name' => 'Demo Import 1', 'local_import_file' => trailingslashit( get_template_directory() ) . 'tdi/demo-content.xml', 'local_import_widget_file' => trailingslashit( get_template_directory() ) . 'tdi/widgets.json', 'local_import_customizer_file' => trailingslashit( get_template_directory() ) . 'tdi/customizer.dat', 'import_preview_image_url' => 'http://www.your_domain.com/tdi/preview_import_image1.jpg', 'import_notice' => __( 'After you import this demo, you will have to setup the slider separately.', 'your-textdomain' ), ), array( 'import_file_name' => 'Demo Import 2', 'local_import_file' => trailingslashit( get_template_directory() ) . 'tdi/demo-content2.xml', 'local_import_widget_file' => trailingslashit( get_template_directory() ) . 'tdi/widgets2.json', 'local_import_customizer_file' => trailingslashit( get_template_directory() ) . 'tdi/customizer2.dat', 'import_preview_image_url' => 'http://www.your_domain.com/tdi/preview_import_image2.jpg', 'import_notice' => __( 'A special note for this import.', 'your-textdomain' ), ), ); } add_filter( 'theme-demo-import/import_files', 'TDI_import_files' );

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 theme-demo-import/after_import filter): ` function TDI_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( 'theme-demo-import/after_import', 'TDI_after_import' ); `

Of course you can, use the theme-demo-import/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 theme-demo-import/before_widgets_import action: function TDI_before_widgets_import( $selected_import ) { echo "Add your code here that will be executed before the widgets get imported!"; } add_action( 'theme-demo-import/before_widgets_import', 'TDI_before_widgets_import' );

You can change the plugin intro text by using the theme-demo-import/plugin_intro_text filter: ` function TDI_plugin_intro_text( $default_text ) { $default_text .= ' This is a custom text added to this plugin intro text.'; return $default_text; } add_filter( 'theme-demo-import/plugin_intro_text', 'TDI_plugin_intro_text' ); ` To add some text in a separate "box", you should wrap your text in a div with a class of 'TDI__intro-text', like in the code example above.

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( 'theme-demo-import/regenerate_thumbnails_in_content_import', '__return_false' );

As a theme author you do not like the location of the "Import Demo Content" plugin page in Appearance -> Import Demo Content? 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 TDI_plugin_page_setup( $default_settings ) { $default_settings['parent_slug'] = 'themes.php'; $default_settings['page_title'] = esc_html__( 'Theme Demo Import' , 'theme-demo-import' ); $default_settings['menu_title'] = esc_html__( 'Import Demo Content' , 'theme-demo-import' ); $default_settings['capability'] = 'import'; $default_settings['menu_slug'] = 'theme-demo-import'; return $default_settings; } add_filter( 'theme-demo-import/plugin_page_setup', 'TDI_plugin_page_setup' ); `

Update: 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.
