Get Comment Info from the WordPress Database

Posted by on

An easy way for visitors to enter their emails is by commenting on a post. We did this recently for people to sign up for a notification email.

Then the trick then is retrieving the comment information from the database for the specific sign-up post.

Clean Up Weird Characters in Database

Posted by on

It’s been a crazy month, with lots of drama all over the place. Here at DigWP.com, we had an episode where the site was all screwed up and not loading or only partially loading, blank white pages, and the whole bit. During the process of keeping it together and trying to restore full functionality, numerous database imports and exports were performed under a variety of circumstance. During the rush, apparently the most recent database backup file was somehow uncompressed outside of MySQL before final import. Several days later, that decompression/unzipping basically converted every quotation mark, em dash, en dash, ellipses and other special characters into some really ugly-looking codes.

Easy Comment Management via SQL

Here are some sweet SQL code snippets for easy comment management. Sometimes it’s easier to modify comment status and delete unwanted comments on a sitewide basis. Using a program like phpMyAdmin makes it so easy to do stuff like remove spam, close/open comments on old posts, enable/disable pingbacks for specific time periods, and so on. Just remember to backup your database before running any queries.

A useful tool to have in in your WordPress toolbelt is the ability to quickly and easily search for, find, and replace specific strings of text directly from the MySQL database. We can do this by entering SQL queries either directly or through one of those handy interface applications like phpMyAdmin, which seems like one of the most prevalent PHP applications on servers today.
