Album Image Uploads

Upload Types

Album-based content using a gallery image as a thumbnail

• The thumbnail is a pointer to one of the album image records.
• In the Content Properties CMS check the use gallery image as thumbnail option.
• To make the edit and delete buttons available when the thumbnail image is clicked:

include (COMMON_TEMPLATE_DIR."forms/images/thumbnail_overlay_buttons.php");

• To insert an editable thumbnail image (either gallery-based or independent) into the edit form or details content include:

include (COMMON_TEMPLATE_DIR."forms/images/select_thumbnail_link_container.php");

• In the page header for the details and edit pages:

$(document).ready(function() {
	$('.image-upload-container').galleries('bindImageOverlayHandlers');
});

Album-based content with thumbnail record independent of the gallery images

• The thumbnail image_link record has the same type_id as the parent content record.
• The gallery images have a different type_id value from the thumbnail image image_link record.

Album-based content that does not require an image upload

• The default setting for images requires that an image is uploaded with each album record that is created.
• In some cases, it may be necessary to allow records to be created without an associated image.
• When creating a new album record, an image_link object is added to its gallery property.
  • This instance is created in the gallery::fill_from_input() routine.
  • By default this image_link object's full->path->required property is set to TRUE.
• To override the default setting, in custom content class derived from the album class override the fill_from_input() routine.

function fill_from_input() 
{
	parent::fill_from_input();
	if (is_array($this->gallery->list) && count($this->gallery->list)>0) {
		$this->gallery->list[0]->full->path->required = false;
	}
}
