Guiding light: Practical experience of PHP and Vue in brain map function development

Brain map is a very useful tool that can help us organize and organize Clearing complex thinking is a tool we often use in work and study. When developing a mind mapping function, using PHP and Vue as development languages ​​is a good choice because they both have powerful functions and rich community resources.

This article will introduce how to use PHP and Vue to develop a simple mind mapping function, and share some practical experiences and code examples.

1. Back-end development (PHP)

In back-end development, we need to create an API to process the data of the brain map, including creation, deletion, update and query.

First, we need to create a database table to store the node data of the brain map. A simple node table can be created using the following SQL statement:

CREATE TABLE `nodes` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title` varchar(255) NOT NULL,
  `parent_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`id`)
);

Next, we create a PHP file to handle API requests, such as api.php. In this file, we need to implement the following functions:

1. Create node:

$app->post('/nodes', function () use ($app) {
  $data = $app->request->getBody();
  $node = new Node($data['title'], $data['parent_id']);
  $node->save();
  echo json_encode($node);
});

2. Update node:

$app->put('/nodes/:id', function ($id) use ($app) {
  $data = $app->request->getBody();
  $node = Node::find($id);
  $node->title = $data['title'];
  $node->parent_id = $data['parent_id'];
  $node->save();
  echo json_encode($node);
});

3. Delete node:

$app->delete('/nodes/:id', function ($id) use ($app) {
  $node = Node::find($id);
  $node->delete();
  echo json_encode(['message' => 'Node deleted successfully']);
});

4. Query node:

$app->get('/nodes/:id', function ($id) use ($app) {
  $node = Node::find($id);
  echo json_encode($node);
});

The above code is a simple example and can be modified and expanded according to actual needs.

2. Front-end development (Vue)

In front-end development, we use Vue to build the user interface and handle user operations. First, we need to install Vue and related dependencies:

npm install vue vue-router axios

Then, we create a Vue component to render the mind map interface, such as MindMap.vue. In this component, we need to implement the following functions:

1. Get brain map data:

mounted() {
  axios.get('/api/nodes/1').then(response => {
    this.node = response.data;
  });
}

2. Add nodes:

methods: {
  addNode(parentId) {
    axios.post('/api/nodes', {
      title: 'New Node',
      parent_id: parentId
    }).then(response => {
      this.node.children.push(response.data);
    });
  }
}

3. Update node:

methods: {
  updateNode(node) {
    axios.put(`/api/nodes/${node.id}`, {
      title: node.title,
      parent_id: node.parent_id
    }).then(response => {
      // 更新成功
    });
  }
}

4. Delete node:

methods: {
  deleteNode(node) {
    axios.delete(`/api/nodes/${node.id}`).then(response => {
      this.node.children = this.node.children.filter(child => child.id !== node.id);
    });
  }
}

The above code is a simple example and can be modified and modified according to actual needs Extension.

Summary:

Using PHP and Vue to develop brain mapping functions is a very good choice. PHP provides powerful back-end processing capabilities, while Vue allows us to easily build highly interactive front-end interface. In actual development, we can also use other libraries to enhance functions, such as database ORM libraries, front-end component libraries, etc.

I hope this article can provide you with some guidance and help in the development of brain map functions, making your development work more efficient and smooth.
