1. COYes. But the problem is that when I introduce a wrong email it should be displayed something like The email field must contain a valid email address. I display the message Las reglas no son validas.

2. COhave the email rule set to be something like $this->form_validation->set_rules('drcorreo','Nombre de usuario', 'trim|required|min_length[5]|xss_clean|callback_puede_entar'); then you will have seperate error messages.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
