Analysis on the artistic method of developing brain map function with PHP and Vue

Brain map is a visual tool that presents information in a tree structure, which can help people better Organize, understand and remember complex information. In web application development, PHP and Vue are two very popular technology stacks. Combining them to implement mind mapping functions can bring good user experience and development efficiency. This article will explore the art of developing mind mapping functions in PHP and Vue, and provide code examples to help readers better understand.

1. Requirements Analysis
Before starting development, we first need to conduct a requirements analysis on the brain map function. Generally, a mind map should have the following functions:

1. Be able to create and edit mind map nodes, including adding, deleting, modifying node content and style, etc.;
2. Be able to expand and contract nodes , allowing users to easily browse and navigate the entire brain map;
3. can support parent-child relationships and sibling relationships between nodes, as well as connection relationships between nodes;
4. supports drag and drop Place nodes to facilitate users to adjust and rearrange nodes.

2. Back-end development

1. Data table design
   We can use the MySQL database to store the node data of the brain map. In order to realize the parent-child relationship and sibling relationship between nodes, we need to design a table to store node information. Specifically, you can create a data table named nodes, containing the following fields:
2. id: node ID, primary key, auto-increment;
3. parent_id: parent node ID, used to represent the parent-child relationship between nodes;
4. name: node name, used to display node content;
5. style: node style, used to modify the appearance of the node.
6. Interface development
   Next, we need to design a back-end interface to handle the addition, deletion, modification and query operations of brain map nodes. You can use PHP frameworks (such as Laravel) for development. The following is sample code for some common interfaces:

• Get all nodes

  // 路由定义
  Route::get('/nodes', 'NodeController@index');
  
  // 控制器方法
  class NodeController extends Controller {
  public function index() {
    $nodes = Node::all();
    return response()->json($nodes);
  }
  }

• Add nodes

  // 路由定义
  Route::post('/nodes', 'NodeController@store');
  
  // 控制器方法
  class NodeController extends Controller {
  public function store(Request $request) {
    $node = new Node();
    $node->parent_id = $request->input('parent_id');
    $node->name = $request->input('name');
    $node->style = $request->input('style');
    $node->save();
    
    return response()->json($node);
  }
  }

• Modify node

  // 路由定义
  Route::put('/nodes/{id}', 'NodeController@update');
  
  // 控制器方法
  class NodeController extends Controller {
  public function update(Request $request, $id) {
    $node = Node::find($id);
    
    if ($node) {
      $node->name = $request->input('name');
      $node->style = $request->input('style');
      $node->save();
      return response()->json($node);
    } else {
      return response()->json(['error' => 'Node not found'], 404);
    }
  }
  }

• Delete node

  // 路由定义
  Route::delete('/nodes/{id}', 'NodeController@destroy');
  
  // 控制器方法
  class NodeController extends Controller {
  public function destroy($id) {
    $node = Node::find($id);
    
    if ($node) {
      $node->delete();
      return response()->json(['message' => 'Node deleted']);
    } else {
      return response()->json(['error' => 'Node not found'], 404);
    }
  }
  }

3. Front-end development

1. Initialize Vue project
   Use the Vue CLI tool to initialize a new Vue project and install the necessary dependencies:

   vue create mindmap-app
   cd mindmap-app
   npm install axios

2. Create components
   Create a file named Mindmap in the src/components directory .vue component, which will be responsible for implementing the brain map function. The following is the sample code of this component:

<template>
  <div>
    <!-- 脑图内容区域 -->
    <div ref="mindmap" class="mindmap"></div>
    
    <!-- 工具栏 -->
    <div class="toolbar">
      <!-- 添加节点 -->
      <button @click="addNode">添加节点</button>
    </div>
  <div>
</template>

<script>
import axios from 'axios';

export default {
  mounted() {
    // 初始化脑图
    this.initMindmap();
    
    // 获取节点数据
    this.fetchNodes();
  },
  methods: {
    initMindmap() {
      // 初始化脑图代码
    },
    fetchNodes() {
      axios.get('/nodes').then(response => {
        // 处理节点数据
      }).catch(error => {
        console.error(error);
      });
    },
    addNode() {
      axios.post('/nodes', {
        parent_id: null,
        name: 'New Node',
        style: ''
      }).then(response => {
        // 处理添加节点后的逻辑
        const node = response.data;
      }).catch(error => {
        console.error(error);
      });
    }
  }
}
</script>

<style>
.mindmap {
  /* 脑图样式 */
}

.toolbar {
  /* 工具栏样式 */
}
</style>

4. Debugging and Optimization
After developing the back-end and front-end code, we can run the PHP back-end server and Vue front-end development server. Perform debugging. You can use Chrome developer tools to inspect network requests and debug code, and optimize according to actual needs.

Summary:
This article explores the art of developing mind mapping functions with PHP and Vue, and provides corresponding code examples. Through reasonable demand analysis, back-end interface development and front-end component development, we can implement a fully functional and user-friendly mind mapping function. I hope this article will be helpful to readers who are developing brain mapping functions.
