Those of you who know a thing or two about SQL know how to write and execute statements to make quick changes to your site and its content. If you are just looking for a simple way to find and replace code and text in your themes and plugins, you should give Real-Time Find and Replace a look. It dynamically replaces code and text after a page is generated but before it is sent to a user’s browser.
The plugin is pretty simple to use. Just enter what you want to search for and replace it with and let the plugin do the rest. Want to use Regular Expressions? No problem. The plugin lets you modify titles, remove unwanted links, and everything else. The pro version includes advanced filtering options (e.g. referrer, post type).
