Special field name

Validating field with special name

When using FormValidation with some server-side frameworks such as CakePHP, Symfony, Rails, Spring, etc, there is a relationship between the model name and the name attribute of the input.

For example, assuming that a user is modeled by the User class with firstName, lastName, username, emails[] properties.

Following the naming convention defined by these frameworks, the inputs in the form of adding a new user might have the name attribute such as:

<input type="text" name="user[firstName]" />
<input type="text" name="user[lastName]" />
<input type="text" name="user[emails][]" />

<!-- or -->
<input type="text" name="user.lastName" />
<input type="text" name="user.firstName" />
<input type="text" name="user.emails[]" />

When using FormValidation to validate those kinds of fields, you must wrap the field name between single or double quotes as follows:

FormValidation.formValidation(
    form,
    {
        fields: {
            'user[firstName]': {
                validators: {
                    ...
                }
            },
            'user[lastName]': {
                validators: {
                    ...
                }
            },
            'user[emails][]': {
                validators: {
                    ...
                }
            },
        },
    }
);
