How to Create and Manage MySQL Triggers in phpMyAdmin April 2, 2025

In this guide, we will walk you through the steps to create a MySQL trigger using phpMyAdmin via your cPanel account.

A MySQL trigger is a set of instructions (SQL code) that automatically executes in response to specific events on a table — such as INSERT, UPDATE, or DELETE operations. Triggers help automate tasks like logging changes, enforcing rules, or recalculating values without needing manual intervention.

Creating a MySQL Trigger in phpMyAdmin:

1. Log in to your cPanel account.
2. Once logged in, go to the “Databases” section and click on the “phpMyAdmin” icon.
   
3. In phpMyAdmin, you will see a list of your databases in the left sidebar. Select the database where you want to add the trigger. All tables within that database will appear in the center panel.
   
4. From the top menu, click on the “Triggers” tab. If no triggers exist yet, the list will be empty. Click on “Add trigger” to begin.
   
5. A configuration popup will appear. Fill in the following fields:
   1. Trigger Name: Provide a descriptive name (e.g., after_update_users).
   2. Table: Select the table to which the trigger will apply.
   3. Timing: Choose whether the trigger executes BEFORE or AFTER the event.
   4. Event: Select the triggering event — INSERT, UPDATE, or DELETE.
   5. Definition: Enter the SQL statement(s) that should run when the trigger is activated.
   6. Definer: Set the definer (usually in the format username@localhost).
      Once all fields are completed, click “Go” to create the trigger.
      

Managing Triggers:
Once the trigger is created, it will be visible under the “Triggers” tab. You’ll see options beside each trigger:

1. Edit – Modify the trigger’s properties and SQL definition.
2. Drop – Delete the trigger permanently.
3. Export – Download the trigger’s SQL code for backup or reuse.
