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

Mon hébergeur est-il pris en charge ?

Oui ! Cette extension devrait être compatible avec n’importe quel hébergeur.

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 feel misled as the 'dry run' option is NOT part of the free plugin but rather a paid option. Imho 'dry run' is essential in any search and replace plugin so advertising this plugin as 'free' is a bit misleading. Technically this plugin is free but unusable (way to dangerous/powerful) as such.

I was going to try doing some search and replacements, and chose to do the 'dry run' first, but apparently you can't view the results from the dry run, without upgrading to the paid version. This effectively makes it less than useless. I'm not going to run a search/replace on a table unless I can preview what's going to be changed first.

This really make my life better. For real. Since I found this plugin al my migrations are FLAWLESS. So simple so good. Thanks a lot!!!

I really wish I had installed this plugin first instead of spending two hours trying to find the bad URLs in the database manually. I installed the plugin and ran a "Dry Run" (no changes) first to find the offending content. I run the search/replace again and it worked perfectly.
