Better Search Replace


When moving your WordPress site to a new domain or server, you will likely run into a need to run a search/replace on the database for everything to work correctly. Fortunately, there are several plugins available for this task, however, all have a different approach to a few key features. This plugin consolidates the best features from these plugins, incorporating the following features in one simple plugin:

  • Prise en charge de la sérialisation pour toutes les tables
  • La possibilité de sélectionner des tables spécifiques
  • La possibilité de faire un « essai à blanc » pour voir combien de champs seront mis à jour
  • Aucune exigence de serveur en dehors d’une installation WordPress fonctionnelle
  • Prise en charge de WordPress Multisite

Time-saving features available in the Pro version:

  • View exactly what changed during a search/replace
  • Backup and import the database while running a search/replace
  • Priority email support from the developer of the plugin
  • Save or load custom profiles for quickly repeating a search/replace in the future
  • Support et mises à jour pour un an

Puis-je endommager mon site avec cette extension ?

Yes! Entering a wrong search or replace string could damage your database. Because of this, it is always adviseable to have a backup of your database before using this plugin.

Comment cela fonctionne-t-il sur un site WordPress multisite ?

When running this plugin on a WordPress Multisite installation, it will only be loaded and visible for Network admins. Network admins can go to the dashboard of any subsite to run a search/replace on just the tables for that subsite, or go to the dashboard of the main/base site to run a search/replace on all tables.

How can I use this plugin when changing URLs?

If you’re moving your site from one server to another and changing the URL of your WordPress installation, the approach below allows you to do so easily without affecting the old site:

  1. Sauvegarder la base de données sur votre site actuel
  2. Install the database on your new host
  3. On the new host, define the new site URL in the wp-config.php file, as shown here
  4. Log in at your new admin URL and run Better Search Replace on the old site URL for the new site URL
  5. Delete the site_url constant you added to wp-config.php. You may also need to regenerate your .htaccess by going to Settings -> Permalinks and saving the settings.

I purchased a Basic install of the PRO version in order to take advantage of the advanced features. I installed it on a staging site, after going through a rather complex licensing process. It didn't solve my issue (wanted to replace a shortcode with a Gutenberg block), but I figured that was my fault because I misread the capabilities. I sent an email asking about that possibility, but received no reply. However, on my live version of the site, I wanted to use it to swap one shortcode for another. I was unable to unlink the license code, so I contacted support. They accused me of trying to game the system by claiming that I'd downloaded the plugin 10 times (only twice, and the second time because I couldn't find my original download file) and that I was trying to use it on multiple sites after buying only a Basic license. I wanted to transfer it from my STAGING to my PRIMARY site, not to a different site. I was NOT trying to transfer to a NEW site. So I am downrating the plugin because their support does not help, and they refused my request of a refund because they wouldn't reset my license for transfer from a staging to a live site.

Love the WP Offload Media plug-in from these guys, so thought I'd give this a try. I had an assistant copy-pasting text from a book we put together in Canva to WordPress posts. At first I forgot to show her to copy just the plain text and ended up with a bunch of unnecessary classes added to our heading and paragraph tags within quite a few posts. Didn't affect anything visually but wanted to get rid of the code bloat. I was able to use this plug-in to find all the 300-400 instances of the unneeded classes within around 90 different posts. Clicking the Search/Replace button worked almost instantly. I also appreciate that the checkbox for "Dry Run" is auto enabled after every run. Would be so easy to screw things up without that! This was all on Flywheel hosting. WordPress 5.7.2
