a) Create a new category attribute

a1) Check your entity types

SELECT * FROM `eav_entity_type`

catalog_category is ID 9

a2) Insert attribute. Table: eav_attribute

entity_type_id = 9
attribute_code = category_pdf
attribute_model = NULL
backend_model = catalog/category_attribute_backend_file
backend_type = varchar
backend_table =
frontend_model =
frontend_input = file
frontend_label = Category PDF
frontend_class =
source_model =
is_required = 0
is_user_defined = 0
default_value =
is_unique = 0
note =

note the new row ID is 950

a3) Define attribute set and group. Make the relation between attribute and entity. Table: eav_entity_attribute

entity_type_id = 9 (Category)
attribute_set_id = 12 ("Default", attribute set - eav_attribute_set)
attribute_group_id = 7 ("General Information", first tab - eav_attribute_group)
attribute_id = 950 ("category_pdf", link with attribute)
sort_order = 0 (order position)

a4) Define attribute properties. Table: catalog_eav_attribute

frontend_input_renderer =
is_global = 1
is_visible = 1
is_searchable = 0
is_filterable = 0
is_comparable = 0
is_visible_on_front = 0

apply_to
is_visible_in_advanced_search = 0
position = 0 (order position)
is_wysiwyg_enabled = 0
is_used_for_promo_rules = 1

a5) Remember to reindex Category Flat Data

b) Create a new frontend attribute type.

We will call it File to handle PDF files.

# List daemons

Useful GUI for launchctl

Some identify daemons

net.culater.SIMBL.Agent is a daemon required for LastPass Safari plugin

This is the case:
Wordpress 2.5 (OLD)
- Flutter

Migration to:
Wordpress 3.2.1 (NEW)
- Magic Fields

My successful process as follows

OLD – WordPress 2.5 all posts / categories / users (current server)
NEW – WordPress 3.x clean instalation (in a new server or localhost)

1) Create a fresh WordPress 3.x (NEW) with the newest version and all plugins like in (OLD)

2) Copy all settings and users manually of admin from OLD to NEW

3) Migrate from Flutter to Magic Fields (OLD)
Before upgrading WP 3.x
a) Deactivate flutter plugin
b) Execute the script to migrate tables http://gist.github.com/558207
c) Rename the name of wp-content/files_flutter to wp-content/files_mf
d) Install plugin Magic Fields
e) Activate it

4) Upgrade WordPress to 3.x and all plugins (OLD)

5) Copy from OLD all files and overwrite NEW

6) Import these tables from server to localhost database
** Do a full replace of your_old_server.com to your_new_server.com **
wp_commentmeta
wp_comments
wp_links
wp_mf* (all wp_mf wordpress_magic fields tables)
wp_postmeta
wp_posts
wpmt_terms
wpmt_term_relationships
wpmt_term_taxonomy

7) You will notice we don’t move wp_options, wp_users… these tables you have to open two browser windows and config all from server to localhost manually.
wp_options especially is the most complicate part and it is like Microsoft Windows. It’s better format with a fresh version than upgrade it.
Why? After several tries this way is much better, if not you will get errors like:
>>> You do not have sufficient permissions to access this page.

That’s it!

What can I do next?

1) See if the website works fine
2) Check the Settings > Reading has the default home page set.
3) Check your Settings > Permanent Links
4) The last one but the most important, you could have some issues with old plugins used on your theme. Check the code, upgrade your plugin or rewrite the old code with new WP3.x features. Happy coding!

Assign SUID to programs

$ chmod 4755 /home/ipascual/scripts/test.sh

I doesn’t work with shell scripts!!!

Linux doesn’t allow you to use SUID root for shell scripts due to security role. Just real binary programs.
The reason is because an attacker could get the computer to execute any shell script when the script is processing to execute. Because of this, modern linux distributions ignore SUID shell scripts.

The solution is to use “sudo”.

What is sudo?

sudo allows a permitted user to execute a command as the superuser or another user, as specified in the sudoers file.
But, sudo asks me for the root! My users still can’t use it whiout password.

Running a shell script without asking for root password

$ sudo visudo

# Add this line at the end
ipascual        ALL=NOPASSWD: /home/ipascual/scripts/test.sh

$ cat /home/ipascual/scripts/test.sh
#!/bin/sh
/sbin/shutdown -h now

$ sudo /home/ipascual/scripts/test.sh

Now the user ipascual will execute test.sh as root without password.

I had to create a script to make my job easier.

Thanks to David Walsh for backup_tables cool function I can share this script to you guys

//3 To upload the full website
$target = dirname(__FILE__)."/website.zip";
