Link Field

Works just like the RedirectorPage URL/Page field
Provides and interface for creating an internal or external link.
Internal link provides a TreeDropdownField for selecting a page within the site tree
External provides a text field for entering the full URL
Also provides availability to store opening in a new tab

Requirements

Silverstripe 4+

Install

composer require iqnection-modules/linkfield

Usage

In your DataObject class, use the DB field "Link"

private static $db = array(
	'LinkedPage' => 'Link'
);

In your forms (CMS only)

$fields->push( IQnection\LinkField\LinkField::create($name,$title) );

setValue() expects either an array or serialized array of the following:

array(
	'Location' => string ['Internal' | 'External'] (required)
	'Internal' => int [SiteTree Page ID]
	'External' => string [external URL | null],
	'NewTab' => [bool]
);

In your templates

<a href="$LinkedPage">Link Text</a>
