Custom PHP 5.3.1 with APC and XDEBUG on (Dreamhost) Shared Host

marco — Wed, 17 Feb 2010 09:35:38 +0000

I’ve recently been setting up my new dreamhost for symfony projects deployment and the only thing the default PHP is missing is the support for APC (alternate php cache). So after looking at the dreamhost wiki I cleaned up and added some features to the one of the install scripts. Here it is for your/mine (future) commodity.

#!/bin/sh
 
# update 16.2.2010 
# @author Marco Bernasocchi 
# - Added OPENSSL LIBMCRYPT LIBTOOL and a promt for installing XDEBUG
#   (still uses XDEBUG 2.05, which has basic PHP 5.3.1 support. 2.1.0 is on its way)
# - removed unsupported php configure switches
# - disabled --with-xsl, if you want to use it you'll probably need to install
#   libxslt (http://xmlsoft.org/XSLT/) version 1.1.0 or greater.
# - sets the ini files into the install directory instead than on cgi-bin
# - to add more domains just copy the cgi binary to the new domain
#   cp "$PHP_BIN_DIR/php-cgi" "$NEW_CGI_BIN_DIR/php.cgi" and modifiy the .htaccess
 
#Script for a minimal PHP 5.3.x install with APC
#
#- Prompts for the domain to build for
#- PHP configure line contains only valid PHP5 options
#- Displays colourful status messages
#- Many build messages, which aren't helpful to most people, are now suppressed
#- Procedurised, making it cleaner and easier to follow
#
#The only things you may want to change in here are marked with "@todo"s
#
#Derived form the original PHP 5.3 install script at
#http://wiki.dreamhost.com/Installing_PHP5

migrating wordpress from gengo to wpml

marco — Sat, 15 Aug 2009 13:13:59 +0000

A client of mine used to have a multilingual blog using the Gengo plugin, which I consider by now unfortunatly dead. Fortunately, the guys at http://www.wpml.org did a great job creating a new plugin that works like a charm.

I did the migration from one to the other and I had no troubles (beside figuring out how to map gengo’s model to wpml). Further down are two SQL statements to check and update the posts language in wpml.

IMPORTANT: first disable gengo, then install wpml, then choose the default language and create the languages you had in geng. All your post will now be in the default language. you can check this with this SQL statement (for example using phpMyAdmin)

SELECT post.`ID`, post.`post_title`, wpml.`language_code` AS wpml_language, gengoLang.`code` AS gengo_language
FROM `wp_posts` post
LEFT JOIN `wp_icl_translations` wpml ON wpml.`element_id` = post.`ID`
LEFT JOIN `wp_post2lang` gengo ON gengo.`post_id` = post.ID
LEFT JOIN `wp_languages` gengoLang ON gengoLang.`language_id` = gengo.`language_id`
WHERE wpml.`element_type` ='post'
ORDER BY post.`ID`  DESC;

Then you can update the post language with the following statement:

UPDATE `wp_icl_translations` wpml
LEFT JOIN `wp_posts` post ON wpml.`element_id` = post.`ID`
LEFT JOIN `wp_post2lang` gengo ON gengo.`post_id` = post.ID
LEFT JOIN `wp_languages` gengoLang ON gengoLang.`language_id` = gengo.`language_id`
SET wpml.`language_code` = gengoLang.`code`
WHERE wpml.`element_type` ='post'

This will update your POSTS only, no category or tags yet. I might look at those as well and I’ll get in touch with wpml to see if they can use my snippets to get out a sort of import tool.

wordpress iphone app with wpml

marco — Fri, 07 Aug 2009 20:30:34 +0000

I’ve a client using a wordpress multilingual blog with the wpml plugin (wpml.org/) and that wants to use the wordpress iphone app (iphone.wordpress.org). The app and the plugin work like a charm. the only problem is that in the app you can’t set the post language, hence you are (well by now were ) able to post only using the default language.
I wrote a small PHP script to put in the root dir of your blog that updates the default language of the blog when called. so basically before using the iphone app you call the script using safari (http://domain.tdl/blog/set_post_lang.php?to=de) and then use the iphone application to post to your blog.
The script requires minimal configuration, you have to set the blog_id (if you have a single install, 0 should be ok, but you can find this by looking at the wp_options table in the DB) and an array of valid languages. Please note that the script uses no authentication methods, up to you to decide if you want to implement it (very easy actually for example with http_auth or with a key). I didn’t because the script does something very small and irrelevant from the security point of view.
And here the code, enjoy.
