After submitting a form, you should validate your data. In Joomla this can be done via the JForm validate method (normally called in the controller via the model JModelForm).

Unlike client-side validation, the validation uses html attributes to do its validation. There is the attribute required ("true" or "required") which makes a field required and the attribute validate with a joomla or custom rule value.

E.g. field in a joomla form xml

<field name="email" type="text" class="inputbox" description="Fill in your E-mail" label="E-mail" required="true" validate="email" size="30" />
