srdb - Search Replace DB for XOOPS

This is a XOOPS adaptation of Search and Replace DB from interconnect/it.

You can use srdb to make database changes when you move a XOOPS installation to a different server or domain, including moving a site to SSL/https.

Quick Start Guide

  • Make a backup of your database!
  • Download and unzip the srdb archive
  • copy the folder to the root of your site
  • open the folder you just uploaded in your browser, i.e.
  • enter the string associated with your OLD site in the replace field, i.e. http://localhost
  • enter the equivalent string for your NEW new site in the with field, i.e.
  • in the Actions section choose dry run to review what will be changed
  • if everything looks correct, choose live run to replace the strings in the database
  • repeat as needed for other strings, such as OLD and NEW server file paths
  • remove the srdb folder from your site (Leaving it is a security risk!)

Going Further

You can be much more precise by choosing certain tables and certain columns to work with.

There are also many other options available, such as converting the MySQL engine used by tables, updating the character sets, and more.

It is also possible to create scripts to run from the command line, allowing you to build and test a conversion to run at a later time. This way you can automate the actual cut-over process to minimize downtime during a site move.

For more information read through the full interconnect/it README below.

If you would like Search Replace DB to detect your WordPress installation, you should install it within a new subfolder within your WordPress installation.

For example, if you have

I get a popup saying there was an AJAX error

This happens occasionally and could be for a couple of reasons:

  • When the script starts, it attempts to start your WordPress or Drupal installation to auto-detect your username and password settings. If this fails, you will see a message informing you that auto-detection failed. You will have to enter your details manually.
  • Script was unable to set the timeout so PHP closed the connection before the table could be processed, this can happen on some server configurations.
  • When using php-fpm (as you have with VVV) make sure that the socket is owned by the server user chown www-data:www-data /var/run/php5-fpm.sock.
You can’t perform that action at this time.
