4 programming languages required to understand WordPress

Learning to develop WordPress begins with many basic questions, including: "In what language is WordPress written?" Another common question is "Should I learn PHP or JavaScript first?" Programming languages ​​are an important topic for site design. We will cover everything you need to get started. Answer "What programming language does WordPress use?" There are four main programming languages. WordPress relies on four languages: HTML, CSS, JavaScript and PHP. Here we introduce each of the technical languages ​​of WordPress.

Html language

HTML: What the web is made of

HTML is a universal part of the web. Every page you see on the Internet with the content inside is marked with some HTML versions. HTML is not really a "programming" language, it is a "markup" language. Stands for HyperText Markup Language. An HTML file is basically a large text document, but it has a "markup" embedded to explain the specific meaning of different bits of text.

This is a complete but very small HTML page. As you can see in HTML most elements are between two different tags (things that are inside more or less characters). For example, the <p> </p> tag is anything inside a paragraph.

Some other elements close themselves, such as <meta charset… /> in this example. Image tags <img/> are another example. It just means that there is nothing "between" opening and closing (like the <p> tag), because things like images do not contain text content.

Elements can be given attributes. In our example, the <p> element (paragraph) was assigned a lorem class. We can use this class to do everything. Probably the most important thing is that we can use a single CSS rule to tell all elements of that class exactly how and in what style they look.

Css language

CSS: Creates a good appearance in HTML

CSS stands for Cascading Style Sheets, a method that is modeled on almost all modern web pages, meaning "having a special look". In CSS, you can style HTML elements such as <h1> tags or HTML attributes, such as the lorem class mentioned earlier.

We first specify which element or elements of the HTML design law affect: In this example, our rule only affects the elements to which the Lorem's class is assigned. (In CSS, classes start with a dot.)

And then inside the bracket we have a set of style properties: property, followed by a colon, the properties of that property, and a comma. New lines come after commas. The important thing about CSS is that you know what features to use to customize the page you want.

Php programming language

PHP: WordPress programming language

PHP is what runs WordPress on your web server. WordPress uses the PHP programming language on the server to build and compile pages. So the most important programming language to really understand WordPress is PHP.

PHP was originally designed to make HTML pages easier. By default it delivers its performance results to an HTML page. The server then shows your site visitors. Logic and basic PHP structures are very important for WordPress templates.

There are some important points for this example:

First, anything that is not inside the PHP tags (<? Php?>) Is just plain HTML. When the server processes the PHP file, it displays it to the visitor just like a regular HTML page.

Variables in PHP start with a dollar sign, such as: $ variable. We first set $ variable to 4, then add 1 to 5 and save it as $ math.

In part of your PHP code, you use the echo command to print anything to the final HTML page. The two lines above the echo combine both regular text strings (in ‘‘ characters ’) with PHP variables. This connection using the point operator is as follows: <? Php echo ‘One and’. ‘Two’; ?>

PHP logic controls any HTML contained in it. This is why the HTML inside the first PHP conditional expression, if it is (true), is shown on the page, but the HTML inside the second sentence, if it is (false).

Javascript language

JavaScript: Web browser programming

JavaScript was invented to be able to program the behavior of HTML pages. For example, if you click on something and it disappears, changes color, or becomes something bigger, JavaScript is probably working.

A WordPress template can work perfectly without JavaScript and run very well. But like most web sites, you see more JavaScript within WordPress templates and the core of WordPress. This is because JavaScript allows for faster, more intuitive interaction, making the page appealing to the visitor and responding to them.

If you just want to learn WordPress, you are mostly familiar with the other three languages, because HTML and CSS are more mandatory and PHP is where a lot of interesting heavyweight work happens. So this article will not talk much about JavaScript and we recommend that you start with a thorough understanding of the other three languages.
