Weakness of codeigniter Form Validation

Codeigniter Form Validation is a very popular validation library. we use this library quite extensively. But it has some short comings. we will discuss the shortcomings here.

the Form Validation library only validates $_POST fields. so, if we have a upload image in our form, this validation library always shows that the uploaded field is empty.

we set the validation rule for our upload field as follows:

$val->set_rules('userfile', 'Profile Picture', 'required');

This is because our uploaded file resides in the $_FILES variable, not in the $_POST field. So, we need to make some way to validate our $_FILES variable.

See my extended Form Validation library for codeigniter. This weakness has been overcome.
