How to use PHP to implement the rich text editor function of the CMS system

Overview:
In modern website development, almost all CMS systems need to provide the rich text editor function to facilitate users Editing and layout of website content. PHP is a very popular server-side programming language. This article will introduce how to use PHP to implement the rich text editor function of a CMS system.

What is a rich text editor?
A rich text editor is a tool that can create and edit rich text content in a web browser. It has functions similar to Word processing software and can insert pictures, links, tables, styles, etc. Common rich text editors include TinyMCE, CKEditor, etc.

Use TinyMCE as a rich text editor:
TinyMCE is a powerful and easy-to-integrate rich text editor. Its integration with PHP is very simple, and it only takes a few steps to realize the rich text editor function of the CMS system.

Step one: Introduce TinyMCE library file
First, download the latest version of TinyMCE and extract it to the project directory of the CMS system. Then, introduce TinyMCE’s JS and CSS files into the pages that need to use the rich text editor.

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>CMS系统富文本编辑器</title>
  <script src="tinymce/js/tinymce/tinymce.min.js"></script>
  <link rel="stylesheet" href="tinymce/css/skins/lightgray/skin.min.css">
</head>
<body>
  <textarea id="editor"></textarea>
</body>
</html>

Copy after login

Step 2: Initialize the TinyMCE editor
After the page is loaded, initialize the TinyMCE editor through JavaScript code.

<script>
  tinymce.init({
    selector: '#editor',
    height: 500,
    plugins: 'link image table',
    toolbar: 'undo redo | styleselect | bold italic | link image table',
    skin: 'lightgray'
  });
</script>

Copy after login

The above code specifies a textarea with the id "editor" as the rich text editor, sets the editor height to 500px, enables link, image, table and other plug-ins, and specifies the toolbar buttons and style.

Step 3: Process the content of the rich text editor
When the user submits the form, the content in the rich text editor needs to be saved to a database or other storage media. In PHP, you can obtain the content of the rich text editor through the POST method and perform related processing.

<?php
  $content = $_POST['content']; // 获取富文本编辑器的内容
  // 进行后续处理，如存储到数据库中
?>

Copy after login

If you need to display the content in the rich text editor in the display page, just get the content from the database and insert it into the HTML.

<?php
  $content = '从数据库中获取的内容'; // 从数据库获取富文本编辑器的内容
  echo $content; // 将内容插入到HTML中
?>

Copy after login

Summary:
It is very simple to use PHP to implement the rich text editor function of the CMS system. By introducing TinyMCE library files, initializing the editor, and processing the contents of the editor, the functions of the rich text editor can be realized.
