<p>The WordPress Importer will import the following content from a WordPress export file:</p>
<ul>
<li>Posts, pages and other custom post types</li>
<li>Comments and comment meta</li>
<li>Custom fields and post meta</li>
<li>Categories, tags and terms from custom taxonomies and term meta</li>
<li>Authors</li>
</ul>
<p>For further information and instructions please see the <a href="https://wordpress.org/support/article/importing-content/#wordpress" rel="ugc">documention on Importing Content</a>.</p>
<h3>Filters</h3>
<p>The importer has a couple of filters to allow you to completely enable/block certain features:</p>
<ul>
<li><code>import_allow_create_users</code>: return false if you only want to allow mapping to existing users</li>
<li><code>import_allow_fetch_attachments</code>: return false if you do not wish to allow importing and downloading of attachments</li>
<li><code>import_attachment_size_limit</code>: return an integer value for the maximum file size in bytes to save (default is 0, which is unlimited)</li>
</ul>
<p>There are also a few actions available to hook into:</p>
<ul>
<li><code>import_start</code>: occurs after the export file has been uploaded and author import settings have been chosen</li>
<li><code>import_end</code>: called after the last output from the importer</li>
</ul>


WordPress Importer


Good for the main use cases: restore from backup, and moving posts between blogs. Unfortunately the image import doesn't seem to work (WordPress 6.3 with plugin 0.8.1), which makes it a pain to clean up image-heavy posts.



One thing I'd like to do with this that I can't is to import another copy of a cross-post and merge the comment threads. As it is, the best I can do is import the duplicate copy and then use another plugin (or dig into the database) to move the comments around.


Works well for moving posts between blogs.

Import posts, pages, comments, custom fields, categories, tags and more from a WordPress export file.

<p>Widget Importer & Exporter is useful for moving widgets from one WordPress site to another, backing up widgets and for theme developers to give users sample widgets. See the <a href="https://churchthemes.com/plugins/widget-importer-exporter/" rel="nofollow ugc">details</a> on ChurchThemes.com.</p>
<h4>Importing</h4>
<p>Importing is done by uploading an export file created by the plugin. The results of an import are shown in a nicely formatted table with an explanation of what happened with each widget area and widget.</p>
<p>Importation takes into consideration widget areas not existing in the current theme (widgets imported as <em>Inactive</em>), widgets that already exist in the same widget area (widgets not duplicated) and widgets that are not supported by the site (widgets not imported).</p>
<h4>Exporting</h4>
<p>Widget Importer & Exporter can create an export file (in JSON format with .wie extension) out of currently active widgets. This file can be imported into other sites using this plugin or used to restore widgets to the same site later.</p>
<h4>Developers</h4>
<p>The <code>wie_before_import</code> action fires after a file is uploaded but before the data is imported. <code>wie_after_import</code> fires after the data is imported. The <code>wie_import_data</code> filter can be used to filter data before it is imported. Other filters are used throughout. Make a pull request on GitHub if you need another hook.</p>

Widget Importer & Exporter

The plugin did what it described - super-easy and quick to use. It even transferred the custom "Conditional Widgets" settings that I had for a few of the widgets.

Well done, mate!
