The tacit partner of PHP and Vue: perfect realization of the brain map function

Brain map is a kind of mind map, often used to organize thinking, record knowledge and provide visualization thinking framework. In web applications, implementing the brain map function can help users better clarify their thoughts and organize information. This article will introduce how to use the tacit partnership of PHP and Vue to perfectly implement the brain mapping function.

1. Implementation Ideas

The implementation of the brain map needs to display the relationship between nodes in a tree structure, and be able to implement operations such as adding, deleting, dragging and editing nodes. In order to realize these functions, we can use PHP as the back-end language for data storage and processing, and use Vue as the front-end framework for page rendering and interaction.

The specific steps are as follows:

1. Create a database table: First, create a table in the database for storing brain map data. The table structure is as follows:

   nodesTable fields: id (node ​​ID), parent_id (parent node ID), title (node ​​title), content (node ​​content)

2. Backend API Implementation: Use PHP to develop back-end API, including node addition, deletion, modification and query functions. The following is a simple API example:

   a) Add a new node:

   <?php
   // 添加节点
   function addNode($parentId, $title, $content){
       // 根据parentId获取父节点信息并插入新节点
       // 这里省略具体实现
       return $newNodeId; // 返回新节点的ID
   }

   b) Delete a node:

   <?php
   // 删除节点
   function deleteNode($nodeId){
       // 根据nodeId删除节点及其子节点
       // 这里省略具体实现
       return true;
   }

   c) Modify a node:

   <?php
   // 修改节点
   function editNode($nodeId, $title, $content){
       // 根据nodeId更新节点标题和内容
       // 这里省略具体实现
       return true;
   }

   d) Query node:

   <?php
   // 查询节点
   function getNode($nodeId){
      // 根据nodeId获取节点信息
       // 这里省略具体实现
       return $node;
   }

3. Implementation of the front-end page: Use Vue for rendering and interaction of the front-end page.

   a) Page structure:

   <template>
     <div>
        <!-- 脑图容器 -->
        <div id="mind-map-wrapper">
            <mindMapItem v-for="node in nodes" :node="node" :key="node.id"></mindMapItem>
        </div>
        <!-- 节点编辑器 -->
        <div id="node-editor" v-show="showEditor">
            <input v-model="currentNode.title" type="text" placeholder="请输入标题"/>
            <textarea v-model="currentNode.content" placeholder="请输入内容"></textarea>
            <button @click="save">保存</button>
        </div>
     </div>
   </template>

   b) Vue component:

   <script>
   import mindMapItem from './mindMapItem.vue';
   export default {
      data() {
         return {
            nodes: [], // 节点列表
            showEditor: false, // 是否显示节点编辑器
            currentNode: {}, // 当前编辑的节点
         }
      },
      mounted() {
         // 初始化获取节点数据
         this.getNodes();
      },
      methods: {
         getNodes() {
            // 调用后端API获取节点数据
            // 这里省略具体实现
            this.nodes = responseData;
         },
         openEditor(nodeId) {
            // 根据节点ID获取节点信息
            this.currentNode = getNode(nodeId);
            this.showEditor = true;
         },
         save() {
            // 调用后端API保存节点信息
            // 这里省略具体实现
            this.showEditor = false;
         }
      },
      components: {
         mindMapItem
      }
   }
   </script>

   c) Note: The mindMapItem component in the above code is used to render a single The HTML structure and style of the node.

2. Summary

Through the tacit partnership of PHP and Vue, we can easily implement the brain map function and provide the ability to add, delete, drag and edit nodes. Wait for operations. PHP, as the back-end language, is responsible for data storage and processing, while Vue, as the front-end framework, is responsible for page rendering and interaction. This combination allows us to more flexibly and efficiently develop mind mapping applications that meet user needs.

Note: This article is for reference only, and the specific implementation needs to be adjusted and improved according to specific needs.
