WordCamp Raleigh 2016 - WP API, What is it good for? Absolutely Everything!Evan Mullins
See the Power of the WP API. Now that every WordPress website has (or will have) an API built-in, what can you do with it? It allows us to further separate the data from the code. Use WordPress to manage our data and then via the API easily access or update that data to power whatever we like. We’ll touch how to set it up and a handful of examples and then explore an iOS app pulling all it’s data and assets from a WordPress site via this API.
This will be geared for developers with some “how to” but also for everyone interested in the power of WordPress and where things are heading.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
How to Make a Field Mandatory in Odoo 17Celine George
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

3. WHAT IS GUZZLE ?
Guzzle is a PHP HTTP client that makes it easy to
send HTTP requests and trivial to integrate with
web services.
Secondly, Guzzle provides a very clean API to work
with. Documentation is very important when
working with a library.Guzzle has done a very good
job by providing a comprehensive documentation
5. OVERVIEW OF COMPOSER
● It's a dependancy manager tool it is used
everywhere in the PHP World. All large
and well-known website components in
other ward it will help you do the
following :
● 1- Install 3rd party php tools and
framewords
● 2- Update version of the tools you use
● 3- Auto load your own code (so in the
future you will only use composer‘s
autoloader!!! Cool ?
●
● Composer has two separate elements :
✔ The first is Composer itself which is a
command line tool for grabbing and installing
what you want to install.
✔ The second is Packagist - the main composer
repository. This is where the packages you
may want to use are stored.
✔ Every thing Composer installs does that in a
directory names vendor which shouldn‘t has
any of your code
6. WORKING WITH COMPOSER
Working with composer will has only 3 task types :
1- Define what you want to install (frame work or tool) in json format file
2- Define where your classes files and configuration file or in the future name
spaces which you want to load in json file
3- Some command files to make composer run the settings you define
4- Require the autoloader of composer in your code
7. WORK SEQUENCE
1
•First Step
•Prepare composer.JSON File to tell composer what you want to install
2
•Second Step
•Prepare composer.json file about your autoload options
3
•Third step
•Run composer install command
8. 1 & 2 COMPOSER.JSON FILE
PREPARATION
The Composer.JSON has
two sections :
Require : The tools that you
want Composer to install
Autoload : where are your
classes and configuration files
for composer to load , in the
future that will be using name
space not classmap.
9. COMMAND LINE
Composer selfupdate
Composer install
Composer dump-autoload
Note :
When call composer install composer
will add some files and a directory with
name vendor in which all 3rd party tools
are
23. I) HTTP VERBS
HTTP Verb: the action counterpart to the
noun-based resource. The primary or most-
commonly-used HTTP verbs (or methods, as
they are properly called) are POST, GET, PUT,
PATCH, and DELETE.
24. GET /addresses.php?id=1
Retrieve the address which number is 1
POST : causes changes in the server
(most cases in create, so it shouldn’t be
repeated, it has a body $_POST
POST /addresses.php
Create new address with the data stored
in the post body
Are there other HTTP verbs ???
25. PUT : The PUT method replaces all current representations of the target resource with the
request payload..
Access PUT using PHP
$_PUT= json_decode(file_get_contents("php://input"),true);
Delete /addresses.php?id=1
update the address which number is 1 with current payload
$_SERVER[“REQUEST_METHOD”] : gives which verb was used GET OR POST,
Delete
26. Delete : Request that a resource be removed; however, the resource
does not have to be removed immediately. It could be an
asynchronous or long-running request.
Delete /addresses.php?id=1
delete the address which number is 1
$_SERVER[“REQUEST_METHOD”] : gives which verb was
used GET OR POST, Delete
28. HTTP STATUS CODES
2xx (Successful): The request was
successfully received, understood, and
accepted (200)
201 Created successfully
202 Deleted successfully
204 Updated successfully
200 request fulfilled
3xx (Redirection): Further action needs to be
taken in order to complete the request (301)
Setting a response code
http_response_code(500)
4xx (Client Error): The request contains bad
syntax or cannot be fulfilled (403 & 404)
403 No access right Forbidden
404 resource not found
405 method not found
402 payment required
401 bad authentication
400 bad request
406 resource not accesptable
5xx (Server Error): The server failed to fulfill
an apparently valid request (500)
500 internal server error
29. REST 101
REPRESENTATIONAL STATE TRANSFER
(transferring representation of resources)
SET OF PRINCIPALES ON HOW DATA
COULD BE TRANSFER ELEGANTLY VIA
HTTP
Each resource has at least one URL
The focus of a RESTful service is on
resources and how to provide access to
these resources.
A resource can easily be thought of as an
object as in OOP. A resource can consist
of other resources. While designing a
system, the first thing to do is identify
the resources and determine how they
are related to each other. This is similar
to the first step of designing a database:
Identify entities and relations.
A RESTful service uses a directory
hierarchy like human readable URIs to
address its resources
http://MyService/Persons/1
This URL has following format:
Protocol://ServiceName/ResourceType/R
esourceID
REST SET OF PRETY URLs
30. REST 101
Avoid verbs for your resource unless the resource is a process such as search
DON’T USE : http://MyService/DeletePerson/1. For Delete a person
RESTful systems should have a uniform interface. HTTP 1.1 provides a set of HTTP Verbs
(GET, POST, DELETE and PUT)
Examples
: Delete http://MyService/Persons/1
Get: http://MyService/Persons/1
Update: http://MyService/Persons/1
POST http://MyService/Persons/
You should use these methods only for the purpose for which they are intended.
For instance, never use GET to create or delete a resource on the server.
Use plural nouns for naming your resources.
Avoid using spaces
31. http://MyService/Persons?id=1
OR http://MyService/Persons/1
The query parameter approach works just fine and REST does not stop you from using
query parameters. However, this approach has a few disadvantages.
Increased complexity and reduced readability, which will increase if you have more
parameters
Use http://localhost/rest01.php/items/10
Not http://localhost/rest01.php?Resources=items&&id=10
$url_piecies = explode("/",$_SERVER["REQUEST_URI"]);
$resource = (isset($url_piecies[2]))? $url_piecies[2] : "" ;
$resource_id =(isset($url_piecies[3]) && is_numeric($url_piecies[3]) ) ?$url_piecies[3] : 0;
32. EXAMPLE OF A REST SERVICE
Resource Methods URI Description
Person GET,POST,PUT,
DELETE
http://MyService/Persons/{PersonID}Contains information about a person, can
create new person, update and delete
persons.
{PersonID} is optional
Format: text/JSON
Club GET,POST,PUT http://MyService/Clubs/{ClubID} Contains information about a club.
can create new club & update existing
clubs.
{ClubID} is optional
Format: text/JSON
Search GET http://MyService/Search? Search a person or a club
Format: text/xml
Query Parameters:
Name: String, Name of a person or a club
Country: String, optional, Name of the
country of a person or a club
33. REST SERVICE STEPS
Receiving the request & identifying it’s parameters ( VERB, RESOURCE, RESOURCE ID,
PARAMETERS)
Logging the request (why?)
Validating the request
If not valid request , send appropriate code and message
If valid request , start dispatching (initialize data access and business logic objects which will
handle the request)
Prepare the response based on the verb (Handler for GET, POST, PUT and DELETE)
If you have a valid response send it with appropriate response after logging it, why?
If you don’t have a valid response response is not of valid, send response code and error after
logging it
Try drawing a flow chart for it
35. REMEMBER BEFORE SEE THE WHOLE
THING THAT
$method = $_SERVER['REQUEST_METHOD’];
Use http://localhost/rest01.php/items/10
Not http://localhost/rest01.php?Resources=items&&id=10
$url_piecies = explode("/",$_SERVER["REQUEST_URI"]);
$resource = (isset($url_piecies[2]))? $url_piecies[2] : "" ;
$resource_id =(isset($url_piecies[3]) && is_numeric($url_piecies[3]) ) ?$url_piecies[3] : 0;
