Writing Custom Validation Rules in Laravel.
Article Introduction：In Laravel, custom validation rules can be implemented in three ways. 1. Use Rule::make to create closure verification rules, which are suitable for simple logic, such as checking whether the mailbox has been registered; 2. Create reusable rule classes, generate and implement validate methods through the Artisan command, which are suitable for large projects or multiple reused logic; 3. Centrally manage verification rules and prompt information in form requests to improve structural clarity and maintenance. In addition, error prompts can be customized by using $fail() or overridden messages() method. These methods effectively enhance the readability and maintainability of verification logic.

Article Introduction：When using the jQuery validation plugin, you may experience verification stuttering when typing in the input field. This is most common when using custom verification rules triggering ajax request to verify user input (for example, checking if the user's email is unique in the database). The lag experience was awful. To eliminate continuous validation checks, add the following parameters to the form validation function:
onkeyup: false,
onclick: false,
onfocusout: false,

Creating Custom Validation Rules in a Laravel Project
Article Introduction：There are three ways to add custom validation rules in Laravel: using closures, Rule classes, and form requests. 1. Use closures to be suitable for lightweight verification, such as preventing the user name "admin"; 2. Create Rule classes (such as ValidUsernameRule) to make complex logic clearer and maintainable; 3. Integrate multiple rules in form requests and centrally manage verification logic. At the same time, you can set prompts through custom messages methods or incoming error message arrays to improve flexibility and maintainability.
