How to create custom user roles

The key to creating a custom user role is to clarify the requirements and allocate permissions reasonably. 1. First determine the role responsibilities and required permissions, list the task list and eliminate unnecessary functions, such as customer service personnel should be able to process orders but cannot modify the price; 2. Use the system's own functions or plug-ins to configure, such as WordPress uses UserRoleEditor, ShopifyPlus to set employee roles, or customize them through code; 3. After the settings are completed, test, log in with the new role to check whether the permissions are appropriate, perform typical operations, and compare the administrator account to find exceptions and make timely adjustments.

How to set up version control for WordPress development

The first step in setting up version control is to install Git and initialize the repository, the second step is to remotely host using platforms such as GitHub for collaboration and backup, the third step is to be careful with WordPress specific files such as themes, plugins, and databases, and the fourth step is to maintain a consistent workflow including branching policies and regular pushes. First install Git locally and initialize the repository through gitinit, create .gitignore files to exclude sensitive or large files; then push the code to a remote platform to take advantage of its collaboration capabilities; then version control of custom themes and plug-ins but avoid tracking third-party content, and manage database and media uploads through tools; finally ensure the development process is smooth and efficient through standardized workflows.

How to delete data using wpdb

Use $wpdb to delete WordPress database data to be operated through the $wpdb->delete() method. The steps are: 1. Get the global $wpdb object; 2. Specify the data table name to be deleted. It is recommended to use $wpdb->prefix to ensure compatibility; 3. Set an array of deletion conditions to ensure accurate WHERE conditions; 4. Optionally pass in formatting parameters such as %d or %s, and automatically recognize them if they are not passed. Notes include: confirming the prefix of the table name, avoiding error deletion, backup or test before execution, and controlling user permissions. The common problems are to enable debugging to view error logs, support deleting multiple records at a time, and do not recommend splicing SQL statements directly to avoid causing security risks.

How to use wp-configphp defines for debugging

When debugging a WordPress site, you can quickly assist in troubleshooting problems through the definition in the wp-config.php file. 1.

How to delete orphaned term meta

There are three ways to delete orphaned term metadata: 1. Automatic cleaning using plug-ins, such as BetterSearchReplace or WP-Optimize, which is simple to operate but requires a reliable plug-in; 2. Manually execute SQL statement cleaning, run DELETE commands through phpMyAdmin or database plug-in, which is more thorough but has a higher threshold; 3. Methods to avoid generating orphan data include merging classification rather than directly deleting, using plug-ins or topics that support automatic processing, and regularly maintaining the database to reduce future problems.

How to secure custom REST API endpoints

Protecting custom RESTAPI endpoints requires starting from four aspects: authentication, permission control, input verification, and monitoring and current limiting. 1. Implement a strong authentication mechanism, such as JWT or OAuth2, and combine HTTPS transmission to reasonably set the token expiration time; 2. Use RBAC to implement fine-grained permission control, perform permission verification at the API layer and add a confirmation mechanism for sensitive operations; 3. Strictly verify all inputs and use built-in tools in the framework to filter sensitive information when output; 4. Deploy monitoring and rate limiting, use Redis to achieve current limiting and analyze abnormal behavior through logs to ensure that the API is safe and controllable.
