Backup & Demo Content

This extension lets you create an automated backup schedule, import demo content or even create a demo content archive for migration purposes.

Demo Content Install

The demo content install might be very useful for your clients. After they install the theme, they won’t need to configure and create content from scratch but instead they can install the demo content you’ve created. Their site will look exactly like your theme demo page, and they can just start to modify and adapt the existing content.

Create Demos

In order to create a demo content archive, just create a Content Backup.

Tip

Before creating a Content Backup for Demo Install use a plugin to remove post revisions.

The next step is to let your users view and select which demo content to install. This page is created in the WordPress admin under Tools > Demo Content Install if the theme has at least one demo content available. The demo content archives can be placed in theme or can be downloaded from a remote server.

Demos bundled in theme

  1. Create Content Backup

  2. Extract the zip in {theme}/demo-content/{demo-name}/

  3. Create {theme}/demo-content/{demo-name}/manifest.php with the following contents:

    <?php if (!defined('FW')) die('Forbidden');
    /**
     * @var string $uri Demo directory url
     */
    
    $manifest = array();
    $manifest['title'] = __('Awesome Demo', '{domain}');
    $manifest['screenshot'] = $uri . '/screenshot.png';
    $manifest['preview_link'] = 'https://your-site.com/demo/awesome';
    
  4. Go to Tools > Demo Content Install menu in the WordPress admin. The demo(s) should be listed on that page.

Demos on remote server

  1. Create Content Backup

  2. Upload the zip on your server (in any directory you want, for e.g. your-site.com/demo/)

  3. Upload this download script, let’s say in the same directory your-site.com/demo/

  4. In the same directory with the download script, create a config.php file and add your demos in the following format:

    //   'demo-id' => '/path/to/demo.zip',
    'awesome-demo' => dirname(__FILE__) .'/awesome-demo.zip',
    
  5. Register the demo(s) in your theme. Add in {theme}/inc/hooks.php:

    /**
     * @param FW_Ext_Backups_Demo[] $demos
     * @return FW_Ext_Backups_Demo[]
     */
    function _filter_theme_fw_ext_backups_demos($demos) {
        $demos_array = array(
            'your-demo-id' => array(
                'title' => __('Demo Title', '{domain}'),
                'screenshot' => 'https://your-site.com/.../screnshot.png',
                'preview_link' => 'https://your-site.com/demo/your-demo-id',
            ),
            // ...
        );
    
        $download_url = 'https://your-site.com/path/to/download-script/';
    
        foreach ($demos_array as $id => $data) {
            $demo = new FW_Ext_Backups_Demo($id, 'piecemeal', array(
                'url' => $download_url,
                'file_id' => $id,
            ));
            $demo->set_title($data['title']);
            $demo->set_screenshot($data['screenshot']);
            $demo->set_preview_link($data['preview_link']);
    
            $demos[ $demo->get_id() ] = $demo;
    
            unset($demo);
        }
    
        return $demos;
    }
    add_filter('fw:ext:backups-demo:demos', '_filter_theme_fw_ext_backups_demos');
    
  6. Go to Tools > Demo Content Install menu in the WordPress admin. The demo(s) should be listed on that page.

Hooks

  • Filter to exclude wp options on database export

    function _filter_theme_fw_ext_backups_db_export_exclude_option($exclude, $option_name, $is_full_backup) {
        if (!$is_full_backup) {
            if ($option_name === 'your-private-option') {
                return true;
            }
        }
    
        return $exclude;
    }
    add_filter(
        'fw_ext_backups_db_export_exclude_option',
        '_filter_theme_fw_ext_backups_db_export_exclude_option',
        10, 3
    );
    
  • Filter to exclude wp options on database restore

    Note

    The current options (if exist) will be wiped out. To keep the current options, use the following filter.

    function _filter_theme_fw_ext_backups_db_restore_exclude_option($exclude, $option_name, $is_full) {
        if (!$is_full) {
            if ($option_name === 'your-special-option') {
                return true;
            }
        }
    
        return $exclude;
    }
    add_filter(
        'fw_ext_backups_db_restore_exclude_option',
        '_filter_theme_fw_ext_backups_db_restore_exclude_option',
        10, 3
    );
    
  • Filter to preserve current wp options values on database restore

    function _filter_fw_ext_backups_db_restore_keep_options($options, $is_full) {
        if (!$is_full) {
            $options[ 'your-special-option' ] = true;
        }
    
        return $options;
    }
    add_filter(
        'fw_ext_backups_db_restore_keep_options',
        '_filter_fw_ext_backups_db_restore_keep_options',
        10, 2
    );
    
  • Filter to register a custom directory that contains theme demos (for e.g. a plugin bundled with theme)

    function _filter_theme_fw_ext_backups_demo_dirs($dirs) {
        $dirs['/path/to/dir-with-theme-demos']
        = 'http://.../uri/to/dir-with-theme-demos';
    
        return $dirs;
    }
    add_filter('fw_ext_backups_demo_dirs', '_filter_theme_fw_ext_backups_demo_dirs');
