How to use MY extended Codeigniter Form Validation Library

We have seen the documentation of Codeigniter Form Validation library. now we will see how we will use it in our coding.

First, we need to download our library. Then we need to place it under the Application-> library folder.

As it is an extended version of Form Validation, so, we can have it by loading our form validation library.


Now we will set rule for our upload field like this:

$this-form_validation->set_rules('userfile', 'Profile Picture', 'required|allowed_types[jpg,png,jpeg]|max_file_size[10]');

By allowed_types[jpg]
Here by allowed_types[jpg,png,jpeg] we mean our allowed types are jpg, png and jpeg. And with max_file_size we set the maximum bytes that is allowed to upload.

$this-form_validation->set_message('allowed_types','Please upload jpg, jpeg and png types');

With this we can set custom messages for our rules.
