New Framework Helps WordPress Plugin Developers Create Persistently Dismissible Admin Notices

Nearly every WordPress user has experienced the frustration of dismissing an admin notice and having it pop up again on page refresh or upon navigating to a new page. WordPress 4.2 made it possible for plugin and theme developers to create dismissible admin notices using the classes .notice and .is-dismissible, but left it up to the developer to ensure that the notices do not return.

Collins Agbonghama, a web developer from Nigeria, decided to create a framework to make it easy to create dismissible admin notices that persist across page loads.

“Although a lot of plugin authors have been able to fix this by adding say a ‘dismiss’ link, this requires extra code to pull off,” Agbonghama said. “This library attempts to fix this with less effort.”

His “Persist Admin Notice Dismissals” library has a plain and sensible name, but it provides an elegant solution for extension authors to use in their themes/plugins. The framework can be autoloaded via Composer or included in a vendor/ directory with the plugin.

Andy Fragen, a contributor on the framework, described how he got involved with the project.

“I opened an issue about 3 weeks ago, asking if the project, which was previously a plugin, could be made into a framework for inclusion into other projects,” Fragen said. “Collins thought it was a good idea and transformed the project from a plugin to a framework.”

Fragen said that Matt Gibbs, a contributor on the GitHub Updater plugin, mentioned dismissing the admin notices that the plugin generates, preferably for some period of time.

“I’ve been looking for a solution since then and when I came across Persist Admin Notice Dismissal I was intrigued,” Fragen said. “I liked the method that Collins was using for his dismissal, as it incorporated well with how I think core works with admin notices.” He decided to jump in and help clean up some code by testing to ensure that the library worked when used in multiple plugins, with multisite, and with autoloaders.

Both Agbonghama and Fragen believe that the framework could be incorporated into core to make it easier for developers to create persistently dismissible admin notices. Agbonghama said he would have commented on the relevant Make/WordPress post but it is now closed to new comments.

“Something like this would definitely make for a feature project and having this built into core would be great,” Fragen said.

Persist Admin Notice Dismissals makes it easier for developers to provide a better experience in the admin while still communicating with users through important notices.
