WordPress theme production tutorial [1] - Understanding WP&structure&index

I have recently started preparing for WordPress theme development. First, we will understand what WP is and the structure of WP in this chapter. Use this article to index to the WP series tutorials written in the future.

(Sorry, don’t worry, we will continue to update...)

1. First, let’s understand what wordpress is and what it can be used for?

WordPress is a blogging platform developed using PHP language. Users can set up their own website on a server that supports PHP and MySQL databases. You can also use WordPress as a content management system (CMS).
WordPress is a personal blogging system and has gradually evolved into a content management system software. It is developed using PHP language and MySQL database. Users can use their blogs on servers that support PHP and MySQL databases.
WordPress has many free templates developed by third parties, and the installation method is simple and easy to use. However, to make your own template, you need to have certain professional knowledge. For example, you must at least understand an application's HTML code, CSS, PHP and other related knowledge under standard universal markup language.
WordPress officially supports the Chinese version, and there are also third-party Chinese language packages developed by enthusiasts. WordPress has thousands of various plugins and countless theme template styles.

2. The current situation and prospects of WordPress

You can learn about it through Baidu. The WordPress platform has now become the basic platform for 18.9% of the world’s websites, with more than 100 million sites.

This is a very large number, and it is very competitive.

I don’t need to say more about its prospects. It’s already very awesome and more people will use it.

2. Advantages and disadvantages of WordPress

Wordpress must be very good if it can win the favor of so many users? So let’s list the

advantages:

There are a large number of themes and plug-ins, and you can easily expand them.

You can easily expand the functions you want. You can transform WP into CMS, SHOP, enterprise website, classified information, etc.

The system is full of hooks, which makes development work very convenient.

The system installation package is relatively small, only 6.9M in size.化 The degree of fragmentation of the system version is low. You can only focus on the development of the latest version without entanglement if you are compatible with the old version.

You can easily search for many website building and usage tips about WP.

Disadvantages:

The system only has 12 tables. These 12 tables can expand many functions, but the efficiency is also reduced.大 Not suitable for building big data large data websites (well optimized)

less system function (this should be the key factor that can be successful)

require_once get_stylesheet_directory() . '/widgets/widget-index.php';

-widgets widget folder
--widget-index.php widget index file (this will control the registration of all widgets)

- -widget-tools1.php specific widget

--widget-tools2.php...

2. Create the file name of the widget in the array widget-{here is the file name that appears in the array} .php

$widgets = array(
'tools1',
'tools2'
);

3. Create
function widget_ui_tools1() {
$widget_ops = array( 'classname' => 'widget_ui_tools1 on top of the widget ', 'description' => 'Display the content of Test 1' );
$this->WP_Widget( true, 'DG-Test 1-Title', $widget_ops );
