Nástroj pro přesun WordPressu jinam

When you’re migrating WordPress (or any other platform using serialized PHP strings in the database) between domains, you must use a safe search and replace method that preserves the integrity of the serialized string lengths. A simple of a dump file for http://localhost to, for example, http://thenewdomain.com is problematic because the length of the string changes but the indexes for the serialized strings does not. Consequently settings are lost and widgets disappear. Not good.

This script can now also handle multiply nested serializations, which can happen in transient values in WP at times, and it can also handle multi-byte Unicode changes safely. This is important now that internationalised domain names are allowed.

It’s worth mentioning that the code will work for any platform that stores PHP serialized arrays in a MySQL database. You can easily use this script on Drupal, Joomla and many other systems where you need to change items across a database without messing up your stored arrays.

**Permalinks Migration**

„http://wordpress.org/extend/plugins/permalinks-migration-plugin-for-wordpress/“:http://wordpress.org/extend/plugins/permalinks-migration-plugin-for-wordpress/

With this plugin, you can safely change your permalink structure – for example, from */%year%/%monthnum%/%day%/%postname%/* to */%category%/%postname%/* – without breaking the old links to your website, and even doesn’t affect your search engine rankings.

But doing so will make all pages indexed by search engines become invalid, moreover, losing visitors from other sites or bookmarks that links to you.

Permalinks Migration plugin is a way to tell the search engines (and browsers) that the page has permenantly moved, and that the old address should be replaced by the new one . This plugin will generates a “301 Redirect” when user or spider visit your site through old permalinks and redirect them to the new permalinks of the same post.

SQL dotazy k nezaplacení

**Náhrada jednoho řetězce za druhý v libovolné tabulce a poli**

/—code php
UPDATE table_name
SET field_name = replace( field_name, ‚tohle_najdi‘, ‚timhle_nahrad‘ );
\—

k nezaplacení např. při přesunu webu na jinou adresu, lze tak nahradit absolutní URL obrázků, siteurl-homeurl nebo guide

/—code php

UPDATE wp_posts SET post_content = REPLACE(post_content, ‚http://stara.cz‘, ‚http://nova.cz‘);
UPDATE wp_posts SET guid = REPLACE(guid, ‚http://stara.cz‘, ‚http://nova.cz‘);
UPDATE wp_options SET option_value = REPLACE(option_value, ‚http://stara.cz‘, ‚http://nova.cz‘);
UPDATE wp_postmeta SET meta_value = REPLACE(meta_value, ‚http://stara.cz‘, ‚http://nova.cz‘);
\—

Tento způsob ale bohužel neřeší případ tzv. „serializovaných dat“:http://stackoverflow.com/questions/11817950/what-is-data-serialization. Při migraci WP na jiné url je proto jistější použít nějaký specializovaný nástroj pro náhradu v serializovaných datech, např.:

„http://pixelentity.com/wordpress-search-replace-domain/“:http://pixelentity.com/wordpress-search-replace-domain/,

„https://interconnectit.com/products/search-and-replace-for-wordpress-databases/“:https://interconnectit.com/products/search-and-replace-for-wordpress-databases/

nebo pluginy „WP Migrate DB“:https://wordpress.org/plugins/wp-migrate-db/ či „Better Search Replace“:https://wordpress.org/plugins/better-search-replace/.

WP Migrate DB migrates your database by running find & replace on URLs and file paths, handling serialized data, and saving an SQL file.

Relativní cesta k obrázkům

Když jsem přesunovala jeden web na jinou doménu, setkala jsem se v podstatě s jedinou větší nepříjemností, a tou byly URL adresy vložených obrázků. Ve WordPressu se do příspěvků vkládají absolutně, což pak je nutné změnit buď příspěvek po příspěvku, nebo jakž takž v zálohované databázi. Ani jedno z toho není nejlepší cesta. Zatím neznám […]
