How thinkphp3 handles data modification of radio button boxes

ThinkPHP3 is a very popular PHP framework. It provides many rich functions, allowing us to quickly develop Web. During the development process, we often use form processing, in which radio button is a common form element. In this article, we will introduce how to use the ThinkPHP3 framework to handle data modification of radio button boxes.

First, we need to create a form containing radio buttons. Here is a basic example with two radio button options:

<form method="post" action="{:U(&#39;edit&#39;)}">
  <input type="radio" name="status" value="1" <?php if($info[&#39;status&#39;]==1): ?>checked<?php endif; ?>> 启用
  <input type="radio" name="status" value="0" <?php if($info[&#39;status&#39;]==0): ?>checked<?php endif; ?>> 禁用
  <input type="submit" value="提交">
</form>

In this example, we set the status of the radio button using $info['status'] Initialization, this is the data that needs to be modified. After the form is submitted, we need to process this data and save it to the database.

In ThinkPHP3, we can use models to handle database operations. The following is a basic model class:

<?php
class TestModel extends Model
{
  protected $tableName = &#39;test&#39;;

  public function saveData($data)
  {
    $this->where('id=' . $data['id'])->save($data);
  }
}

We can update the specified data by calling the $model->where($where)->save($data) method, Among them, $where is a conditional statement used to limit the data that needs to be modified, and $data is the data that needs to be updated.

Next, we need to create a Controller class to handle form submission. In this class, we need to get the form data and pass it to the model for processing. The following is a basic Controller class:

<?php
class TestController extends Controller
{
  public function edit()
  {
    if(IS_POST)
    {
      $data = I(&#39;post.&#39;);
      $model = new TestModel();
      $model->saveData($data);
    }
  }
}

In this example, we first determine whether the form has been submitted. If so, obtain the form through I('post.') data, and then instantiate a model object through new TestModel(), and pass the data to the saveData() method for processing. In this way, we can modify the radio button data.

In short, processing the modification of radio button data is not a particularly complicated task. You only need to be proficient in the basic usage skills of the ThinkPHP3 framework to easily implement this function. I hope this article can be helpful to everyone.
