Details

Change footer content

You can replace the entire content in the footer of the login component with your custom content.

<adf-login ...>
    <login-footer><template>My custom HTML for the footer</template></login-footer>
</adf-login>`

Change header content

You can replace the entire content in the header of the login component with your custom content.

<adf-login ...>
    <login-header><template>My custom HTML for the header</template></login-header>
</adf-login>`

Extra content

You can put additional html content between alfresco-login tags to get it rendered as part of the login dialog. This becomes handy in case you need to extend it with custom input fields handled by your application or parent component:

<adf-login ...>
    <div>
        <div>Your extra content</div>
    </div>
</adf-login>

Here's an example of custom content:

Custom logo and background

It is possible changing logo and background images to custom values.

<adf-login 
    [backgroundImageUrl]="'http://images.freeimages.com/images/previews/638/wood-wall-for-background-1634466.jpg'"
    [logoImageUrl]="'http://images.freeimages.com/images/previews/eac/honeybee-with-a-house-1633609.jpg'">
</adf-login>

Should give you something like the following:

Alternatively you can bind to your component properties and provide values dynamically if needed:

<adf-login
    [backgroundImageUrl]="myCustomBackground"
    [logoImageUrl]="myCustomLogo">
</adf-login>

Customize Validation rules

If needed it is possible to customise the validation rules of the login form. You can add/modify the default rules of the login form.

MyCustomLogin.component.html

<adf-login 
    [fieldsValidation]="customValidation"
    #alfrescologin>
</adf-login>

MyCustomLogin.component.ts

export class MyCustomLogin {
    
    @ViewChild('alfrescologin')
    alfrescologin: any;

    customValidation: any;

    constructor(public router: Router) {
        this.customValidation = {
            username: ['', Validators.compose([Validators.required, Validators.minLength(8), Validators.maxLength(10)])],
            password: ['', Validators.required]
        };
    }

    ngOnInit() {
        this.alfrescologin.addCustomValidationError('username', 'minlength', 'Username must be at least 8 characters.');
        this.alfrescologin.addCustomValidationError('username', 'maxlength', 'Username must not be longer than 11 characters.');
    }
}

Controlling form submit execution behaviour

If absolutely needed it is possible taking full control over form submit execution by means of executeSubmit event. This event is fired on form submit.

You can prevent default behaviour by calling event.preventDefault(). This allows for example having custom form validation scenarios and/or additional validation summary presentation.

Alternatively you may want just running additional code without suppressing default one.

MyCustomLogin.component.html

<adf-login 
    (executeSubmit)="validateForm($event)" 
    #alfrescologin>
</adf-login>

MyCustomLogin.component.ts

export class MyCustomLogin {

    validateForm(event: any) {
        let values = event.values;
        
        // check if the username is in the blacklist
        if (values.controls['username'].value === 'invalidUsername') {
            this.alfrescologin.addCustomFormError('username', 'the
            username is in blacklist');
            event.preventDefault();
        }
    }
    
}

Please note that if event.preventDefault() is not called then default behaviour will also be executed after your custom code.
