WordPress Importer

Description

The WordPress Importer will import the following content from a WordPress export file:

  • Posts, pages and other custom post types
  • Comments
  • Custom fields and post meta
  • Categories, tags and terms from custom taxonomies
  • Authors

For further information and instructions please see the Codex page on Importing Content

Filters

The importer has a couple of filters to allow you to completely enable/block certain features:

  • import_allow_create_users: return false if you only want to allow mapping to existing users
  • import_allow_fetch_attachments: return false if you do not wish to allow importing and downloading of attachments
  • import_attachment_size_limit: return an integer value for the maximum file size in bytes to save (default is 0, which is unlimited)

There are also a few actions available to hook into:

  • import_start: occurs after the export file has been uploaded and author import settings have been chosen
  • import_end: called after the last output from the importer

Help! I’m getting out of memory errors or a blank screen.

If your exported file is very large, the import script may run into your host’s configured memory limit for PHP.

A message like “Fatal error: Allowed memory size of 8388608 bytes exhausted” indicates that the script can’t successfully import your XML file under the current PHP memory limit. If you have access to the php.ini file, you can manually increase the limit; if you do not (your WordPress installation is hosted on a shared server, for instance), you might have to break your exported XML file into several smaller pieces and run the import script one at a time.

For those with shared hosting, the best alternative may be to consult hosting support to determine the safest approach for running the import. A host may be willing to temporarily lift the memory limit and/or run the process directly from their end.

Reviews

I was excited to find this but now a little sad

The one time out of several I tried using the importer to export and then import media and/or posts, it seemed to work but it pulled over a bunch of short code that was maybe the fault of the theme I was pulling from. That said I tried just pulling some media files from one WP install to another and it got the titles but every single image file failed to import from the export files. I am inspired to seek other solutions at this point. If I try again to use it and my experience changes I will update this rating but for now it is barely worth the one star.
