Installation

Installation via composer:

$ composer require littlegiant/silverstripe-image-points

Usage

Model

Include the point in your model.

use LittleGiant\SilverStripeImagePoints\DataObjects\Point;

By default the image point will use the model's Image, which is a required relationship your model needs. This is needed so you can ad points to something...

private static $has_one = [
    'Image' => Image::class
];

private static $has_many = [
    'ImagePoints' => Point::class . '.PointOf'
];

private static $owns = [
    'Image'
];

Simply add/edit the points using a gridfield.

$fields->addFieldsToTab('Root.ImagePoints', [
    new GridField('ImagePoints', 'Image Points', $this->ImagePoints(), $myGridfieldConfig),
]);

YAML

Set the height/width of the image in your yml config to set the aspect ratio of the image.

LittleGiant\SilverStripeImagePoints\DataObjects\Point:
  image_width: 1918
  image_height: 822

Template

Usage in the template.

<ol>
  <% loop $ImagePoints %>
    <li style="top: {$YPos}%; left: {$XPos}%;">
      <h4>{$Title}</h4>
      <p>{$Content}</p>
    </li>
  <% end_loop %>
</ol>
