HomePHP FrameworkThinkPHPExamples to explain how to add data in thinkphp5

thinkphp5 is a PHP framework that is very suitable for beginners. It is easy to use and supports rapid development. If you want to add data to your web application, here are some first steps.

1. Preparation work

Before you start adding data, you need to ensure that you have completed the following preparation work:

  • You have created a table and have Connected to the database
  • You have installed the latest version of thinkphp5 framework
  • You have created a model and corresponding controller and view files

2. Create Form for adding data

The first step in adding data in thinkphp5 is to create a form. Here we start with the most basic functions. First, you need to create a form in your view file and set the form submission URL to point to a method of the controller:


In the above code, we used {:url('Index/add ')} function generates the URL to submit the form, which points to the add method in our controller.

3. Add controller method

Next, you need to add an add method in your controller file, which will read the data in the form and store the data into the database .

public function add(){
    //判断请求方式是否为POST方式
    if(request()->isPost()){
        //接收POST数据
        $data=input('post.');

        //数据验证
        $validate = validate('ModelName');
        if (!$validate->check($data)) {
            $this->error($validate->getError());
        }

        //将数据添加到数据库
        $result = db('tableName')->insert($data);
        if($result){
            $this->success('添加数据成功!',url('Index/index'));
        }else{
            $this->error('添加数据失败!');
        }
    }else{
        return $this->fetch();
    }
}

In the above code, we first determine whether the request method is POST, then receive the data in the form and perform data verification. Finally, insert the verified data into the database and jump to the data list page. If an error occurs, an error message is returned.

4. Add data validation rules

In the process of adding data, you need to ensure the validity and integrity of the data. Data can be verified using the validation function provided by thinkphp5. In thinkphp5, the validator is a component used to verify user input data. In the previous controller code, we used the validate() function to create a validator. In the model, we can set validation rules:

protected $validate=[
    'field1|字段1'=>'require|unique:table1',
    'field2|字段2'=>'require|email',
    ...
];

In the above code, we use require, unique, and email validation rules. These rules can ensure that the data in the form meets certain specifications.

5. Traverse the added data

After you successfully add some data, you may need to view all added data on the list page. At this time, you need to add an index method to the controller and traverse all the added data in the corresponding view file:

public function index(){
    $data = db('tableName')->select();
    $this->assign('data',$data);
    return $this->fetch();
}

In the above code, we query all the data in the database and Inject data into the view file through the assign() method. Traverse all data in the view file:

<tbody>
    {volist name="data" id="vo"}
        <tr>
            <td>{$vo.id}</td>
            <td>{$vo.field1}</td>
            <td>{$vo.field2}</td>
            ...
            <td>
                <a>$vo['id']))}">编辑</a>
                <a>$vo['id']))}" onclick="return confirm('确定要删除吗?')">删除</a>
            </td>
        </tr>
    {/volist}
</tbody>

In the above code, we used the volist tag to traverse all data, and then added edit and delete buttons after each row of data.

Summary

Adding data is a very basic operation in web application development. In the thinkphp5 framework, the process of adding data can be divided into preparation, creating forms, adding controller methods, adding data validation rules and traversing the added data. If you follow the steps above, you should be able to complete the process of adding data easily. At the same time, these steps are also the basis for other operations in web application development.
