What is WordPress Hook: admin_post
The admin_post hook in WordPress is a specific hook that allows developers to perform custom actions after a form is submitted on the admin side of the website. This hook is commonly used to process form data and perform various tasks such as saving settings, updating database records, or sending notifications.
Understanding the Hook: admin_post
The admin_post hook is located within the WordPress admin-post.php file, which handles form submissions on the admin side of the website. When a form is submitted, the admin_post hook is triggered, allowing developers to execute custom functions and processes.
Hook Parameters (if applicable): admin_post
The admin_post hook accepts parameters such as the action parameter, which is used to specify the custom action to be performed when the form is submitted. Additionally, developers can pass additional parameters to the hooked function to process form data or perform other tasks as needed.
Hook Doesn’t Work: admin_post
If the admin_post hook doesn’t work as expected, it may be due to incorrect action parameter values, improper function implementation, or conflicts with other plugins or themes. To troubleshoot, developers should double-check the action parameter values, review the hooked function for errors, and deactivate other plugins or themes to identify conflicts.
Best Practices & Usage Notes (if applicable): admin_post
When using the admin_post hook, it’s important to validate and sanitize form data to prevent security vulnerabilities. Additionally, developers should ensure that the hooked function performs necessary checks and error handling to handle various scenarios and provide a smooth user experience.

function custom_form_submission_handler() {
// Validate and sanitize form data
// Process form data and perform necessary tasks
