Block Plus

By Daniel Berthereau Add some new blocks for the static pages and improve some of the existing ones (image gallery, D3 graph, mirror page, search form, assets, item set showcase, exhibits, etc.).

Block Plus (module for Omeka S)

New versions of this module and support for Omeka S version 3.0 and above are available on GitLab, which seems to respect users and privacy better than the previous repository.

Block Plus is a module for Omeka S that adds some new blocks for the static pages and improves some of the existing ones: image gallery, D3 graph, mirror page, search form, assets, item set showcase, exhibits, footnotes, etc.

Furthermore, each block can use multiple templates, so it's possible to theme a block differently in different pages.


First, install the optional module [Generic] if wanted.

The module uses external js libraries for some blocks, so use the release zip to install it, or use and init the source.

  • From the zip

Download the last release from the list of releases (the master does not contain the dependency), and uncompress it in the modules directory.

  • From the source and for development:

If the module was installed from the source, rename the name of the folder of the module to BlockPlus, and go to the root module, and run:

composer install --no-dev

Then install it like any other Omeka module.

See general end user documentation for Installing a module and follow the config instructions.


Select them in the view "Page edit". You may theme them too: copy the block templates that are in view/common/block-layout/ in the same place of your theme.

Improvements in all blocks

The core blocks (Browse preview, Html, Item metadata, Item showcase, List of pages, List of sites, Page title, Table of contents) are improved with two new options:


Most of the blocks have an option to set a title.


Most of block have an option to set a specific template, so it’s possible to display these blocks differently in the same page or on different pages.


When a block allows to select a template, the filename must start with the same string than the original template, for example "table-of-contents-pages.phtml" for the block "TableOfContents".

Furthermore, it should exists in a module or in the current theme. When the template is missing, for example when switching into another theme, the default of the template is used. Thereby, when the module or the theme that has this template is replaced, you have to check the pages that use it.

New blocks and specific improvements

Asset (improvement)

Since the integration of "asset" in Omeka 3.1, this block is an improved version of the core block "asset". It can list assets with optional link to pages, labels and caption. The assets are not required to be filled, so it allow to display any list of contents.

Unlike the upstream version, it has a specific class option at asset level and supports templates. Some templates are available: "asset-block", "asset-hero-bootstrap", "asset-left-right" and "asset-partners".

Block Metadata

This block provides the same information than the view helper pageMetadata() (see below), but from a block. It is usefull with the simple block to extract params, or to get some informations about the page from anywhere in the theme.

// A simple check is done to make the theme more generic.
$blockMetadata = $plugins->has('blockMetadata') ? $plugins->get('blockMetadata') : null;
if ($blockMetadata):
    $data = $blockMetadata('params_key_value');

Browse preview (improvements)

The block Browse preview has new fields to display sort headings and pagination, so it's now possible to have a specific list of items, like the main browse view.

It has some specific templates too: - simple carousel ("browse-preview-carousel"): this is an upgrade of the plugin Shortcode Carousel for Omeka Classic. - gallery display with a quick viewer too ("browse-preview-gallery"). This one has a specific option to add to the query to display thumbnails as square or medium: thumbnail_size=medium. You can see an example on the site Ontologie du christianisme médiéval en images, from French Institut national de l’histoire de l’art.

To use them, simply select the wanted template:


D3 Graph

The D3 graph adds the D3 library to display relations between items in a graph: links between subjects and objects, links between items and item sets, etc.

External content

Similar to media with html, but to display an external asset that is not a resource neither an asset file, so currently not manageable inside Omeka. It may be used to display a html text with a video on the home page.

HTML (improvements)

Two new options are added in main settings:

  • Display the html field as a document, that is a lot easier when editing long articles. Furthermore, the field can be maximized.
  • Use the default or advanced toolbar. The advanced toolbar is the CKEditor one and contains more possibilities to edit advanced text.

Furthermore, it is possible to add footnotes inside each html field.

Item Set showcase

This is similar to the block Item Showcase, but for item sets.

Mirror page

Allow to use a page as a block, so the same page can be use in multiple sites, for example the page "About" or "Privacy". Of course, the page is a standard page and can be more complex with multiple blocks. May be fun. This is an equivalent for the shortcode as a page in Omeka Classic too.

Page date

Display the date of the creation and/or modification of the current page. See Omeka issue #1706.

Redirect to URL

Allow to redirect the page to another page, inside or outside Omeka. It is useful for hard coded links in the footer, to keep track of some clicks, to use the page item/browse as a the home page, or some other use cases.

Resource with html

Simplify the display of a media on the left or the right (see user guide). It is the same block that existed in Omeka Classic [Exhibit file-text].

Search form

Include a specific search form in a specific page. The default query may be adapted to the page via the theme.

Search form and results

Create a full search page with a simple or complex form and the results on the same page. All options should be managed via the theme. To replace item/browse, item-set/browse and even media/browse, you may need to set the page as default action for the search in default template common/search-form.


Allow to set a div with a specific class between two blocks. May be useful to fix some css issues, or to increase space between some blocks.


Allow to wrap a block or multiple block with a div. in particular to create columns. Divisions can be nested. The css should be prepared in the theme to managed them. By default, only a simple aside column of 30% is available with class column align-right (or left).

Simple block

A simple block allow to display a template from the theme. It may be used for a static html content, like a list of partners, or a complex layout, since any Omeka feature is available in a view.

Tree view

An example layout is provided to display a dynamic tree view from a tsv/csv file. The file should be one value by a row, with the offset matching the depth:


A second example is a template to create a standard glossary (definition list):

alpha = First letter of Greek alphabet
beta = Second letter of Greek alphabet

The glossary can be created with html too with the block html and template html-glossary. In that case, set a list of term and definition separated by an empty line:

definition of alpha

definition of beta
definition of beta continued…

To insert a line, it is recommended to set the cursor at the start of the line. It will avoid possible issues.


This is a showcase for any resource, site, page, asset or url. It's an improved and genericized version of item showcase.

Table of contents (improvement)

The table can be displayed from the root if wanted.


Display the last messages from an account on Twitter. To use it, you may use your own developer bearer token, else the module will try to use an anonymous one.

Technical note: Since December 2020, it is required to get a dev account to fetch messages of a user, because Twitter disabled any standard html endpoint (see this issue on StackOverflow). If you use a dev account, it is not necessarily the one of the thread to follow.

Nevertheless, it is still possible to fetch them with an anonymous bearer token. To get it, check the urls in the dev tools of your browser in the "network" tab. The token is set in the header of the requests to with the key Authorization, for example AAAAAAAAAAAAAAAAAAAAANRILgAAAAAAnNwIzUejRCOuH5E6I8xnZz4puTs%3D1Zv7ttfk8LF81IUq16cHjhLTvJu4FA33AGWWjCpTnA. This token will be available for the next two years, or less. Anyway, the module fetches it automagically. Nevertheless, it uses some hard coded urls that may change.

Check how to generate a bear token. You need to create an app in your account too. If you can't, try to check the option to use the Api version 1.1.

In all cases, there is a rate limit, but generally largely enough for a common digital library.

Theme view helpers

Page Metadata

Allow to add a type to the page, so it’s simpler to have different templates for different pages. It allows in particular to create exhibits inside a site, without creating a new site.

You can add new types in the settings of the site. Then, in your theme, you can get the page type $pageType = $this->pageMetadata('type'); and many other data about the page. If the page is an exhibit, it is possible to build a specific navigation menu of this exhibit too, like in the site Fondation de la Maison de Salins.

To manage multiple types, it’s generally required to edit the template "view/omeka/site/page/show.phtml" of your theme and to add a check:

// A simple check is done to make the theme more generic.
$pageMetadata = $plugins->has('pageMetadata') ? $plugins->get('pageMetadata') : null;
if ($pageMetadata):
    $type = $pageMetadata('type') ?: null;
    switch ($type):
        case 'home':
            $class = 'home';
            // Specific html code…
        case 'exhibit':
            $class = 'exhibit';
            // Specific html code…
        case 'exhibit_page':
            $class = 'exhibit-page';
            // Specific html code…
        case 'simple':
            $class = 'simple-page';
            // Specific html code…
            // Generic html code…
            $class = 'page';
    $this->htmlElement('body')->appendAttribute('class', $class);
    // …

Pages Metadata

This view helper allows to get the data of all pages of the same type in the current site. For example, you can get all "exhibit_page". Multiple types can be retrieved at once.

// A simple check is done to make the theme more generic.
$pagesMetadata = $plugins->has('pagesMetadata') ? $plugins->get('pagesMetadata') : null;
if ($pagesMetadata):
    $data = $pagesMetadata('exhibit_page');


  • [ ] Merge more similar blocks into a main block (with automatic upgrade).
  • [x] Integrate Shortcodes (module Shortcode)
  • [x] Integrate Menu (module Menu)
  • [ ] Integrate attachments for block Showcase
  • [ ] Integrate sidebar forms for block Showcase
  • [ ] Auto-create asset when image is uploaded in a Html field.
  • [ ] Update site of mirror page to get good url for $resource->siteUrl().


Use it at your own risk.

It’s always recommended to backup your files and your databases and to check your archives regularly so you can roll back if needed.
