WordPress.org

When submitting the comment form, WordPress by default reloads the complete page. In case of an error (e.g. an invalid e-mail address or an empty comment field) the error message is shown on top of a new (blank) screen and the user has to use the browser's back button to correct the comment form and post the comment again. The WP-Ajaxify-Comments WordPress plugin hooks into any WordPress theme and adds AJAX functionality to the comment form: When the comment form is submitted, the plugin sends the data to the WordPress backend without reloading the entire page. In case of an error, the plugin shows a popup overlay containing the error message and the user can correct the comment form without navigating back. If the comment was posted successfully, the plugin adds the (new) comment to the list of existing comments without leaving the page and shows an information overlay popup.

Live demo: You can try out a live demo in the blog post i've written for the initial release of the plugin.

Since the plugin hooks (on client-side) into the theme to intercept the comment form submit process and to add new comments without reloading the page, the plugin needs to access the DOM nodes using (jQuery) selectors. The plugin comes with default values for these selectors that were successfully tested with WordPress' default themes "Twenty Ten", "Twenty Eleven", "Twenty Twelve".

Summarized the WP-Ajaxify-Comments plugin hooks into your theme and improves the usability of the comment form by validating and adding comments without the need of complete page reloads.

Important: If the plugin does not work out of the box with your theme, custom selectors could be defined in the plugin's admin frontend. If you don't succeed in configuring the proper selectors please don't hesitate to ask a question in the plugin's support forum or send me a private message. The plugin is highly customizable and I'm not aware of conflicts to any themes or other plugins that cannot be resolved. I would kindly ask you make a small (PayPal) donation when I'm able to find a working configuration for your customized WordPress page. All donations save future development and support of the plugin. Thanks in advance! You can find more troubleshooting information on the FAQ page.
