How to exclude specific data from display in thinkphp

When developing using the thinkphp framework, it is often necessary to exclude specific data from display to improve the quality and efficiency of the program. This article will introduce how to exclude specific data and display it under the thinkphp framework.

Generally, we need to exclude certain data for display. For example, we have a user table with a column that records the status of users being disabled. When we display the user list, Do not want disabled users to be displayed. So how to quickly implement this function?

The idea is to add a filter condition during data query to filter out the data that meets the conditions.

In the thinkphp framework, we can implement this function through model query. First, we need to define a model, such as UserModel.

<?php  
namespace app\model;
use think\Model;

class UserModel extends Model {
    // 模型对应的数据表名
    protected $table = &#39;user&#39;;
}

In the above code, we define a UserModel model, and the corresponding data table is named user. Next, we can call the model in the controller and add filter conditions.

<?php  
namespace app\controller;
use app\model\UserModel;

class UserController {
    public function userList() {
        // 创建UserModel对象
        $userModel = new UserModel();

        // 查询条件
        $where = [
            &#39;is_disabled&#39; => 0, // 只查询未禁用的用户
        ];

        // 查询数据
        $userList = $userModel->where($where)->select();

        // 返回数据并渲染视图
        return view('userList', ['userList' => $userList]);
    }
}

In the above code, when we query user data, we add a filter condition to query only non-disabled users (is_disabled = 0) and filter out disabled users. This way we can exclude specific data and display it.

The idea is relatively simple, but it should be noted that in actual development, we often need to consider multiple situations at the same time and use multiple query conditions to filter. At this time, you can use ThinkPHP's built-in query expressions to help complete multi-condition queries.

For example, if we want to query users who are over 18 years old and whose gender is female, we can write like this:

$where = [
    'age' => ['egt', 18],
    'gender' => 'female',
];
$userList = $userModel->where($where)->select();

In the above code, we use the query expression egt to represent greater than Equal, gender uses the equal query expression, so that we can complete multi-condition queries.

To sum up, the way to exclude specific data under the thinkphp framework is to add filter conditions when querying data. It should be noted that we need to use query expressions flexibly to meet the needs of multi-condition queries.
