With WordPress, all of your content is stored in a database (called a MySQL database or SQL file) on your server, not page files. This means that if you need to make global changes to your content like replacing text or links throughout your site, these changes have to be made inside your WordPress database tables.
Editing WordPress database tables, however, requires having knowledge of MySQL. If you are a non-coder and need to make global changes to content on your website, the best way to do this is to use a WordPress plugin.
In this tutorial, you will learn how to use plugins to easily perform a global search and replace in WordPress without touching code or editing your WordPress database tables.
How To Do A Global Search And Replace In WordPress
Being able to perform search and replaces quickly is important if you have many instances of text or links that need replacing, for example:
- Changing a product/brand name or multiple product descriptions,
- Replacing staff member names, telephone numbers, physical addresses, email addresses, etc.
- Replacing misspelled words
- Translating words
- Changing internal/external website URLs
Imagine the following scenarios:
Also, let’s say that your WordPress site includes many published posts and pages containing images stored inside your WordPress media folder.
As your site grows and new posts and pages get added, you then decide to move all of your images and media to an external storage location (e.g. Amazon S3) to help improve your site’s efficiency and make your pages load faster to visitors …
(Transferring images to other storage locations require replace image URLs on existing content)
This move changes the path (i.e. the destination URL) of your images, which requires changing the URLs of all the images that you have included in your posts and pages.
In most situations, it would be quite impractical to go through every post and page on your site and do a manual search and replace of all image links. Fortunately, if you are a non-tech-savvy WordPress user, plugins provide a simple solution you can use to search and replace content throughout your site without having to access your WordPress database.
If you transfer images to a different image storage location without changing the URL of the images in your content, your posts and pages will continue displaying images stored in the old location (e.g. your WordPress images folder).
If you delete your images from the WordPress images folder or change image URLs before transferring images to the new location, your posts and pages will display “missing image” errors …
(Incorrect image links cause missing image errors)
When transferring images published on existing content to a different storage location, follow the steps shown in the order below to avoid errors:
- Add images to the new location
- Write down the destination path to the new images folder
- Perform a global search and replace to change the old path URL to the new destination using a search and replace plugin
- Delete images from the old folder or just ignore these.
- All of your image links will now point to the new storage location.
