How to write api in code igniter form validation
The downside of this validation is the user has to submit the data to the server for processing and wait for the response. Execution of the form submission is also aborted.
How to create api in codeigniter step by step

This permits you to extend the validation class to meet your needs. If there is an error, the message will appear. Execution of the form submission is also aborted. Note: You can host unlimited applications on a single server. We also learned how- to set validation rules and out error messages using CodeIgniter's built-in validation library. If you submitted something invalid, or perhaps missed a required item, the form is redisplayed containing your data along with an error message describing the problem.
You fill it in and submit it. Data sanitization — the validation library also has capabilities that remove malicious code from the submitted data for security reasons. The password field must match the password confirmation field.

The disadvantage of client-side validation is the user has control over it. Unique Validation If we want to validate the contact number to ensure that we do not save the same number twice, we can use the following rule to do that.
In summary, the tutorial project builds a contacts management app that will store the details in the database. However, the benefit of using the helper is that it generates the action URL for you, based on the URL in your config file.
