Migration project update

I’ve spent the past few days building functionality for what I’ve termed the “relocate” component — the class that handles sitesite (versus network, blog)-wide replacement of old URLs with new. A pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party UIUI User interface is in the work.

Two discoveries were made in the process of coding the relocate component.

  1. Attachment locations have been stored as relative paths since 2.7, which helps with keeping them portable. However, I have seen full paths in the database tables of sites that started up pre-2.7; transitioning those to portable relative paths will be part of what I’m building.
  2. By using WordPress queries and post functions (as opposed to SQL queries) to replace within post content, we gain the advantage of storing those changes in revisionsRevisions The WordPress revisions system stores a record of each saved draft or published update. The revision system allows you to see what changes were made in each revision by dragging a slider (or using the Next/Previous buttons). The display indicates what has changed in each revision., rather than indiscriminately touching all entries in the posts table in the way that was previously documented on the Codex.

With the guidance of WP CLI’s explanation for how to set up a plugin for testing, I’ve also coded unit tests to verify that things are working as they should. One hurdle I faced in unit testing was that update_option('siteurl') doesn’t affect the value of the WP_CONTENT_URL constant until the next execution of the script, by which time the unit testunit test Code written to test a small piece of code or functionality within a larger application. Everything from themes to WordPress core have a series of unit tests. Also see regression. framework will have rolled back the transaction. This minor quirk won’t translate to real world use, although I’m not sure if I’m satisfied with the way I overcame it.

Finishing the UI for this component is my timeline’s task for this week; it will facilitate a user’s decision to change the site URLURL A specific web address of a website or web page on the Internet, such as a website’s URL www.wordpress.org to a different domain. I’ll makemake A collection of P2 blogs at make.wordpress.org, which are the home to a number of contributor groups, including core development (make/core, formerly "wpdevel"), the UI working group (make/ui), translators (make/polyglots), the theme reviewers (make/themes), resources for plugin authors (make/plugins), and the accessibility working group (make/accessibility). sure installation/usage instructions are shown by next week.

Happy Canada Day!
