Get all posts by post meta key and meta value

Description

For some situations, we need to get all the posts which have specific meta key and meta value.

We can do it with the help of the WP_Query class.

Example

Note: I’m giving you an imaginary example just for a reference to understand, In which situation you can use below code snippet.

Suppose,

  • We have a custom post type properties.
  • We have 15 properties are published.
  • We have store the location of each property in meta key property-location
  • And, We want to get all the properties which meta key is property-location with meta value Pune.

Code Snippet

$query_args = array(
	'post_type'  => 'properties',
	'meta_query' => array(
	    array(
			'key'   => 'property-location',
			'value' => 'Pune',
	    ),
	)
);

$query = new WP_Query( $query_args );

Here,
post_type is our custom post type slug. In our example its properties.
key is meta key. In our example its property-location
value is meta value. In our example its Pune

Gist Snippet

You can use below complete gist code snippet for reference.
Note: In below code snippet you need to change the parameters as you need.


Here,
I have added some extra parameters to optimize the WordPress query.

  • fields with value ids which return ONLY array post IDs of all found items.
  • no_found_rows with value true which optimizes the query.
  • posts_per_page with value -1 to get all the posts. Default it return only 10 items.

Keyboard shortcut/aliases for the WP CLI, Git, Grunt & PHPCS commands for windows

In development, We spend a lot of time on the command line. We type a lot of commands on regularly.

I have created a shortcut for the most of the commands which I use on a daily basis some of them are below:

WP CLI

Command Keyboard Shortcut/Aliases
wp theme list wpthl
wp plugin list wppll

Check all the available WP CLI commands etc. (all WP CLI commands list)

Example 1. Using shortcut wpthl instead of wp theme list

Example 2. Using shortcut wppll instead of wp plugin list

Some more commands with keyboard shortcuts/aliases are below:

Grunt

Command Keyboard Shortcut/Aliases
grunt release grr
grunt minify grm

PHPCS

Command Keyboard Shortcut/Aliases
phpcs pb
phpcbf pbf

Git

Command Keyboard Shortcut/Aliases
git add . gaa
git commit –message gcm
git checkout gco
git pull origin gpu
git push origin gpp
git status gs

To create keyboard shortcuts using aliases is very simple. We can create any command shortcut/aliases.

Follow below simple steps:

  1. Open the file .bashrc which is found in location  C:\Users\USERNAME\.bashrc and
  2. Add below sample commands of Git & Grunt.

I found the article Terminal/Bash Command-Line Shortcuts with Aliases written by @jonsuh to create keyboard shortcuts for the Terminal/Git Bash.

I have added some more commands of Grunt, WP CLI & PHPCS on my local environment.

Using absint() in WordPress

It convert a value to non-negative integer.

Internally this function used abs( intval( $maybeint ) ).


You can try below examples yourself.

Examples Output var_dump
absint( 0 ) 0 int(0)
absint( '0' ) 0 int(0)
absint( 1 ) 1 int(1)
absint( '8' ) 8 int(8)
absint( -27 ) 27 int(27)
absint( '-8' ) 8 int(8)
absint( 'abc' ) 0 int(0)
echo absint( 0 );
// Output: 0 
// var_dump() int(0)

echo absint( '0' );
// Output: 0 
// var_dump() int(0)

echo absint( 1 );
// Output: 1 
// var_dump() int(1)

echo absint( '8' );
// Output: 8 
// var_dump() int(8)

echo absint( -27 );
// Output: 27 
// var_dump() int(27)

echo absint( '-8' );
// Output: 8 
// var_dump() int(8)

echo absint( 'abc' );
// Output: 0 
// var_dump() int(0)
