WordPress – Loop Post Links by Year

Code swiped from http://wordpress.org/support/topic/list-all-posts-on-a-page-split-them-by-year

<?php
// Get years that have posts
$years = $wpdb->get_results( “SELECT YEAR(post_date) AS year FROM wp_posts WHERE post_type = ‘post’ AND post_status = ‘publish’ GROUP BY year DESC” );

// For each year, do the following
foreach ( $years as $year ) {

// Get all posts for the year
$posts_this_year = $wpdb->get_results( “SELECT ID, post_title FROM wp_posts WHERE post_type = ‘post’ AND post_status = ‘publish’ AND YEAR(post_date) = ‘” . $year->year . “‘” );

// Display the year as a header
echo ‘<h2>’ . $year->year . ‘</h2>’;

// Start an unorder list
echo ‘</ul>’;

// For each post for that year, do the following
foreach ( $posts_this_year as $post ) {
// Display the title as a hyperlinked list item
echo ‘<li><a href=”‘ . get_permalink($post->ID) . ‘”>’ . $post->post_title . ‘</a></li>’;
}

// End the unordered list
echo ‘</ul>’;
}

Open MYSQL for remote connections

https://rtcamp.com/tutorials/mysql/remote-access/

Change mysql config

Start with editing mysql config file

vim /etc/mysql/my.cnf

Comment out following lines.

#bind-address           = 127.0.0.1
#skip-networking

If you do not find skip-networking line, add it and comment out it.

Restart mysql server.

service mysql restart

Change GRANT privilege

You may be surprised to see even after above change you are not getting remote access or getting access but not able to all databases.

By default, mysql username and password you are using is allowed to access mysql-server locally. So need to update privilege.

Run a command like below to access from all machines.

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'%' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

Run a command like below to give access from specific IP.

mysql> GRANT ALL PRIVILEGES ON *.* TO 'USERNAME'@'1.2.3.4' IDENTIFIED BY 'PASSWORD' WITH GRANT OPTION;

You can replace 1.2.3.4 with your IP. You can run above command many times to GRANT access from multiple IPs.

You can also specify a separate USERNAME & PASSWORD for remote access.

You can check final outcome by:

SELECT * from information_schema.user_privileges where grantee like "'USERNAME'%";

Finally, you may also need to run:

mysql> FLUSH PRIVILEGES;

Test Connection

From terminal/command-line:

mysql -h HOST -u USERNAME -pPASSWORD

If you get a mysql shell, don’t forget to run show databases; to check if you have right privileges from remote machines.

git commands

from https://confluence.atlassian.com/display/STASH/Basic+Git+commands 

Git task Notes Git commands
Tell Git who you are Configure the author name and email address to be used with your commits.Note that Git strips some characters (for example trailing periods) from user.name. git config --global user.name "Sam Smith"git config --global user.email sam@example.com
Create a new local repository 
git init
Check out a repository Create a working copy of a local repository: 
git clone /path/to/repository
For a remote server, use: 
git clone username@host:/path/to/repository
Add files Add one or more files to staging (index): 
git add <filename>

git add *
Commit Commit changes to head (but not yet to the remote repository): 
git commit -m "Commit message"
Commit any files you’ve added with git add, and also commit any files you’ve changed since then: 
git commit -a
Push Send changes to the master branch of your remote repository: 
git push origin master
Status List the files you’ve changed and those you still need to add or commit: 
git status
Connect to a remote repository If you haven’t connected your local repository to a remote server, add the server to be able to push to it: 
git remote add origin <server>
List all currently configured remote repositories: git remote -v
Branches Create a new branch and switch to it: 
git checkout -b <branchname>
Switch from one branch to another: 
git checkout <branchname>
List all the branches in your repo, and also tell you what branch you’re currently in: 
git branch
Delete the feature branch: 
git branch -d <branchname>
Push the branch to your remote repository, so others can use it: 
git push origin <branchname>
Push all branches to your remote repository: 
git push --all origin
Delete a branch on your remote repository: 
git push origin :<branchname>
Update from the remote repository Fetch and merge changes on the remote server to your working directory: 
git pull
To merge a different branch into your active branch: 
git merge <branchname>
View all the merge conflicts:View the conflicts against the base file:Preview changes, before merging: git diffgit diff --base <filename>

git diff <sourcebranch> <targetbranch>
After you have manually resolved any conflicts, you mark the changed file: 
git add <filename>
Tags You can use tagging to mark a significant changeset, such as a release: 
git tag 1.0.0 <commitID>
CommitId is the leading characters of the changeset ID, up to 10, but must be unique. Get the ID using: 
git log
Push all tags to remote repository: 
git push --tags origin
Undo local changes If you mess up, you can replace the changes in your working tree with the last content in head:Changes already added to the index, as well as new files, will be kept. 
git checkout -- <filename>
Instead, to drop all your local changes and commits, fetch the latest history from the server and point your local master branch at it, do this: 
git fetch origin

git reset --hard origin/master
Search Search the working directory for foo(): git grep "foo()"
