Conflict

This module has a direct conflict with Linkable.

Example usage

class Page extends SiteTree
{
    private static $has_one = array(
        'ExampleLink' => 'Link'
    );

    public function getCMSFields()
    {
        $fields = parent::getCMSFields();

        $fields->addFieldToTab(
            'Root.Link',
            LinkField::create(
                'ExampleLinkID',
                'Link to page or file'
            )
        );

        return $fields;
    }
}

In your template, you can render the links anchor tag with

{$ExampleLink}

Template options

Basic usage

<!-- has one relationship -->
{$ExampleLink}

<!-- many relationship -->
<% loop ExampleLinks %>
    {$Me}
<% end_loop %>

Define link classes

<!-- has one relationship -->
{$ExampleLink.setCSSClass(button)}

<!-- many relationship -->
<% loop ExampleLinks %>
    {$setCSSClass(button)}
<% end_loop %>

Define a custom template to render the link

<!-- has one relationship -->
{$ExampleLink.renderWith(Link_button)}

<!-- many relationship -->
<% loop ExampleLinks %>
    {$renderWith(Link_button)}
<% end_loop %>

Define a custom style. This will apply a css class and render a custom template if it exists. The example below will look for Link_button.ss in the includes directory.

<!-- has one relationship -->
{$ExampleLink.setStyle(button)}

<!-- many relationship -->
<% loop ExampleLinks %>
    {$setStyle(button)}
<% end_loop %>

Custom template

<% with ExampleLink %>
    <% if LinkURL %>
        <a href="{$LinkURL}"{$TargetAttr}{$ClassAttr}>
            {$Title}
        </a>
    <% end_if %>
<% end_with %>

CMS Selectable Style

You can offer CMS users the ability to select from a list of styles, allowing them to choose how their Link should be rendered. To enable this feature, register them in your site config.yml file as below.

Link:
  styles:
    button: Description of button template # applies button class and looks for Link_button.ss template
    iconbutton: Description of iconbutton template # applies iconbutton class and looks for Link_iconbutton.ss template

Limit allowed Link types

Globally limit link types. To limit types define them in your site config.yml file as below.

Link:
  allowed_types:
    - URL
    - SiteTree

To limit link types locally for each field. It is important to note that defining local types does not inherit from global but instead overrides it.

LinkField::create(
    'ExampleLinkID',
    'Link Title'
)
->setAllowedTypes('URL','Phone')
