- How to use thinkphp5 to clear session
- 1. The basic concept of session. What is session? Simply put, session is a server-side storage technology that can save user data on the server side. Session works as follows: When a user visits a website for the first time, the server automatically assigns a unique session_id to the user and saves the session_id in the user's browser. When the user performs other operations, the server will find the corresponding session based on the session_id in the browser, and then read or modify the data saved in the session. When the user closes the browser, the server destroys the

- How thinkphp outputs sql statements
- ThinkPHP's SQL debugging ThinkPHP provides a very easy-to-use class library to process SQL statements: the Db class library. This class library integrates a large number of functions for convenient database operation. By using this library, we can easily build and execute SQL queries. In this process, we need to print or output query statements in order to debug or optimize the application. The next section will detail how to output SQL statements. Outputting a SQL Query When we execute a query operation, we want to see the SQL statement that was executed. SQL statements can be output through the following code: //Assume $table is the name of the data table $result=D

- How to perform controller jump in ThinkPHP framework
- 1. Use the redirect method of the Controller object to implement jump In ThinkPHP, you can implement the jump through the redirect method of the Controller object. This method can accept two parameters, the first parameter represents the URL address of the jump, and the second parameter represents the parameter information that needs to be passed when jumping. The specific implementation steps are as follows: Call the redirect method in the controller method, for example: publicfunctionindex(){//Jump to the hello method $this->redirect('hello');} in the configuration

- What are the ThinkPHP queries for PHP?
- 1. Aggregation query In applications, we often use some statistical data, such as the number of current users (or those who meet certain conditions), the points of all users, the average score of users, etc. ThinkPHP provides a method for these statistical operations. A series of built-in methods. Get the number of users: Db::table('think_user')->count();//Assistant function db('user')->count(); 2. Use the where method for time query. The method supports time comparison, for example: // Greater than a certain time where('create

- How to set up static in ThinkPHP5
- 1. What is staticization? Staticization is a means of converting dynamically generated content of web pages into static HTML files, allowing users to directly access static pages when accessing, thereby improving website performance. When a user accesses a dynamic page, the server will go through some processing, such as PHP parsing, database query, etc., before returning the page to the user. Staticization uses the caching mechanism to generate the page when the user accesses the dynamic page. Static files are cached on the server and user requests are redirected directly to the static files to reduce the load on the server. 2. Static settings in ThinkPHP5 There is no static function by default in ThinkPHP5, but you can

- How to implement the image rotation and cropping function in the thinkphp framework
- Step 1: Install the thinkphp framework. If you want to use the thinkphp framework in your own development, you naturally need to install it into your own project. The installation of thinkphp is very simple. You only need to move the decompressed compressed package directly into the project root directory. After moving, you only need to modify the entry file index.php in the project to start using thinkphp. Step 2: Introduce the image processing class in thinkphp. Introduce the image processing class in the thinkphp framework to operate images, which mainly include basic processing methods such as scaling, cropping, and rotation. Among them, rotation cropping is the focus of this article. Add the following code in the controller to introduce the image processing class: us

- How to add fields after data query in ThinkPHP
- 1. Query data Let’s first review how to query data in ThinkPHP. In the controller, we can query data through the following code: $User=M('User');$list=$User->where('status=1')->select();$this->assign ('list',$list);$this->display();The above code realizes the processing of data with status equal to 1 in the data table named User.

- How thinkphp passes GET parameters
- First, in ThinkPHP, we can pass parameters through URL addresses. The parameters in the URL address will be automatically parsed by the ThinkPHP framework and passed to the corresponding controllers and methods. For example, our URL address is: http://localhost/index.php/Index/index?id=1&name=thinkphp, where id=1 and name=thinkphp are the parameters passed. In the controller, we can use the $this->request->param() method to get the parameters passed in the URL address. For example:

- How to call mysql field in thinkphp
- 1. Create database tables and data. Before performing database operations, we need to create the database and corresponding data tables. Suppose we have a student management system and need to create a data table named student to store basic information about students. The table contains the following fields: id: primary key, self-increasing. name: student name, varchar type, length 20. age: student age, int type. sex: student gender, varchar type, length 2. t_score: CET-4 test score, int type. total_score: total student scores, int type. We can create this data table using the following SQL statement: C

- What are the commonly used import settings in thinkphp?
- 1. Import files When using the ThinkPHP framework, we need to introduce some class libraries within the framework into our program so that we can use the functions it provides. In ThinkPHP, we can use the following two methods to import files. Introducing the framework default file The framework default file is stored in the framework directory. We can introduce it in the following way: require_once'framework/thinkphp.php'; This will introduce the framework default file into the current file, making it easier for us to use the functions of the framework. . Introducing specified files In some cases we do not need to introduce the entire framework into our program

- How to solve the problem that thinkphp cannot obtain post data
- 1. Problem After submitting the form, the post data cannot be obtained through request->param() or $this->request->param(), and an empty array is obtained. 2. Cause of the problem: The enctype attribute is not set in the form. When the form is submitted, if the enctype attribute is not set, the default data transmission method is application/x-www-form-urlencoded. At this time, the post data will be placed in the http request header instead of the request body. Therefore, when getting post data, we need to use $this->re

- How to implement jump page in thinkphp
- 1. Use the redirect function to jump to pages In thinkphp, you can use the redirect function to jump to other pages. The usage of this function is as follows: publicfunctionredirect($url,$params=[],$code=302,$withPrefix=false). Among them, $url represents the page path to be jumped, and $params represents the parameters that need to be passed when jumping. $code indicates the HTTP status code of the jump, and $withPrefix indicates whether to include the domain name prefix. Here are some examples of using this function: 1. Methods of jumping to other controllers // Jumping to the index of the Home controller

- How to perform conditional query in ThinkPHP
- 1. Use the where method to add query conditions. In ThinkPHP, query conditions can be added using the where method. The where method supports two parameters: the first parameter is the query condition, and the second parameter is the binding parameter of the query condition. For example, if we want to query the record with id 1 or id 2 in our code, we can use the following code: $map['id']=array('eq',1);$map['id']= array('eq',2);$data=M(&am
