Useful Drupal modules

Click on the module name for notes, comments, patches.
Recommendations (for and against) are my personal opinion only and may be out of date. Feel free to email with corrections/suggestions.

Why haven't you mentioned Drupal 9? As of February 2022 I've updated all the sites I look after to Drupal 9 (experience: mixed). I haven't decided how to label future version compatibility as D10 will be coming soon as well. The upgrade_status module is superb. You're bound to have issues with composer. Also watch out for a nasty session headers bug with redirect_after_login.

What about sites still running Drupal 7? In short I still recommend leaving them on Drupal 7. Your decision is really if you will gain anything from Drupal 8/9 and for many then answer will be no, and one of the main hassles - apart from converting each content type one at a time, and setting up a new theme, will be recreating all your views by hand, as views can't be automatically upgraded.

Any text in the notes
Name D8 Sort descending Personally Tested Last Updated
Pathologic (pathologic) 2018-11-22

d.o. page

There's a D8 version but I've only tested D7.

It's a filter that fixes incorrect paths in your content - e.g. if you have content with an old domain or IP address specified, you can redirect it.

Node access user reference (nodeaccess_userreference) 2022-08-11

d.o. page

"Essential"

Allows you to use an entity reference field on a node to allow (or deny) access to that node to the users you have selected.  Extremely useful for giving selected people access.

This isn't available in D8 or above (though it ought to be) - there's a note in the issue queue about it.  #2655426

Node Export (node_export) 2018-11-20

d.o. page

Tto actually export node content. An 8.x version has begun development:

composer require 'drupal/node_export:1.x-dev'

Mydropwizard (mydropwizard) 2019-03-13

d.o. page

"Essential"

If you have a Drupal 6 site, this modifies your Available Updates page (/admin/reports/updates) with direct download and release note links to all the D6 LTS (Drupal 6 Long Term Support) releases. 

Restrict Login or Role Access by IP Address (restrict_by_ip) 2017-02-08

d.o. page

Can specify single IP address or ranges. Two modes: restrict login, so they can only login from certain IPs, and restrict role, so they can login from anywhere but only access a role's permissions from the defined IPs. There's a D8 dev branch, last updated June 2016.

Node Page Disable (node_page_disable) 2020-11-05

d.o. page

"Essential"

Adds an checkbox labelled 'Retain /node as an active url?' to /admin/config/system/site-information

This lets you disable the /node page which would otherwise list all published content.

Note it doesn't let you individual disable /node/xxx access by content type - see restrict_node_page_view or rabbit_hole for that.

This is for D7 only - in D8 you go to /admin/structure/views and disable /node there.

Resave nodes (resave_nodes) 2020-04-21

d.o. page

"Essential"

If you want to manually refresh a series of nodes.
Mainly useful if you have a rule or a hook that relies on a node being saved, to update a computed field etc.

You can choose the node type.

Autofocus (focus) 2017-02-08

d.o. page

Autofocuses the first field of form (forms can be specified).  No sign of a D8 port.

Table trash (table_trash) 2020-04-26

d.o. page

Add extra tables JS support for views (and many other pages) - e.g. search box, dynamic column sorting, rearranging columns, exporting to clipboard etc.

If you get "TypeError: tables.DataTable is not a function" when using datatables module, first, try going to /admin/config/content/table_trash/global_settings and saving the existing settings.

Administration Views (admin_views) 2019-12-21

d.o. page

"Essential"

D7 only (as this is in D8 core as standard).

Converts /admin/people into a fully-fledged configurable view (i.e. fields, filters, exposed filters, header/footer, pagination settings etc.) 

(Dependency: views_bulk_operations)

Autosave (autosave) 2017-02-08

d.o. page

Saves snapshot of content type form using AJAX.  Content types and save frequency can be configured.  No sign of a D8 port yet.

Automatic Nodetitles (auto_nodetitle) 2017-02-07

d.o. page

You can hide a node's title field (for reference, every node has to have a title) and generate it automatically, similar to pathauto.  No-one's porting this to D8 yet.

View Migration (view_migration) 2018-11-23

d.o. page

Not recommended

Migrate views from D7 to D8.
Once installed on D7 - you need to go to /admin/config/view-migration 
It outputs multiple YML files and you're specifying a directory to put them in, which you need to create first.

My experience of the YAML output has been:

- incomplete (e.g. multiple missing displays in a complex view, views without a machine name)
- invalid UTF8 due to the next and previous arrows in pager.options.tags being encoded wrong
- the dependencies section at the top of the file not being set out correctly

It doesn't look like there's much current development activity (likewise migrate_views, which is the other plugin people usually mention).

Flood Control (flood_control) 2017-02-08

d.o. page

Protect against brute-force login attacks. Unclear what's happening with porting of this.

Views Aggregator Plus (views_aggregator) 2021-05-12

d.o. page

Provides extra options for aggregating data in tables - e.g. grouping sets of rows together and summing the values of particular fields.

Has a hook - hook_views_aggregation_functions_info() - which lets you add your own options to the table aggregation settings - e.g.  supposing you have a limit for something (number of tickets, nights of accommodation) and want to decrement it - you can write a method to sum the matching rows and then do a calculation on the total.

Also supports 'add column function' - adds a grand total (or other summary field) at the very bottom of the table.

Caution - this module breaks hook_views_pre_render() - you can write your own pre_render method to remove or shuffle entire rows, but any chances to values will be overwritten (discovered this by looking through the source and looking for the use of that hook).  The workaround is to try and do what you need to by using hook_views_aggregation_functions_info() instead.

Alexa (alexa) 2017-02-06

d.o. page

Integrates with Amazon Echo. Allows Drupal to respond to Alexa skills requests.  See Dries' blog with video demo.

Field collection (field_collection) 2017-02-08

d.o. page

Allows you to group a set of fields together.  In active development for D8 but still a lot of open bugs at time of writing - project page says it will likely be replaced by Paragraphs.

Configuration Read-only (config_readonly) 2018-12-07

d.o. page

Lock all configuration changes via the admin UI - e.g. if you need to lockdown a production environment.

config_readonly now has a whitelist, added via an array in settings.php.

Password policy (password_policy) 2018-11-26

d.o. page

Not recommended

There are still quite a few bugs open. I dropped this for a project, partly because it adds a load of clutter with the 'resets' and reset dates.
The minimum password policy in Drupal is already 12 characters anyway (and one issue is changing the minimum length doesn't change the help text.) 
You need to enable the submodules to use the various constraints:
drush pm:list | grep 'password_policy_'
Admin users see password policy stuff on the user profile page.
You need to set password reset days to 0 if you don't want to enforce a reset policy.
Policies can be applied by role.  
You get a generic warning about the password 'not matching the password policy'. Suggest using string overrides to change the "To change the current user password, enter the new password in both fields." message users see.
Instructions: add/edit the policy, click next, choose constraint then click 'Configure constraint settings' otherwise you won't be able to change anything.
It also lets you do a forced reset by role.

Automatic Entity Label (auto_entitylabel) 2018-11-20

d.o. page

"Essential"

Hide entity labels (i.e. titles) or auto-generate them. (Works for anything - nodes, comments, taxonomies).

Field Formatter Condition (fico) 2018-11-21

d.o. page

(based on ffc which hasn't been ported to D8).  

Allows you to configure field display based on value.  Adds a 'Conditions' pane to the cog in Manager Display of all entities (so content types but also comment types, e.g. if you have comments with multiple fields)

Requires Display Suite (ds)

Note: if you wanted to hide say a checkbox when it's value is false - you can do in it core with Manage Display - turn the label off then set (via cog wheel) the output format to Custom, and you can enter a value for true and leave false blank - exactly the same widget for boolean values you use when setting the output of a field in a view.

Webform Views Integration (webform_views) 2018-11-26

d.o. page

"Essential"

This module lets you add fields from submissions to view, and sort/filter the view on them, in the same way you would standard fields from the Field API.

It's still alpha and not as polished/robust as the webform module itself - but it's certainly OK to use in production provided you test things first - check every combination of exposed filters works, and double check you aren't seeing duplicate rows (right now I've locked it to a recent commit on the dev-5.x branch, which doesn't need any patches).

Menu position (menu_position) 2020-01-26

d.o. page

"Essential"

Assign various pages (by content type, URL, role etc.) to certain menu entries - so the 'active' status of the menu is set correctly (i.e. they appear within the sections you want).

- patch: Add enabled checkbox to edit form + enable new rules by default

As of alpha2 - views with contextual filters (e.g. myview/somefilter) will work correctly when a rule is added with pages / pages with wildcards specified.

 

Conditional Fields (conditional_fields) 2021-08-10

d.o. page

Adds a 'Manage dependencies' tab to the admin page for content types.

This lets you set a 'target field' whose visibility is set according to a 'control field' and whether the latter is full/empty/checked/unchecked/has a specific value.

Another useful feature is you can prefill/pre-tick etc. the target field (including with a custom text value, for example).

To detect quickly if it's in use anywhere (I needed to do this before being sure I could uninstall the module on a site), export your site config and grep the /config/sync directory for 'conditional_fields' - it's stored in the 'third_party_settings' key in core.entity_form_display.node.[content type].default.yml

Refreshless (refreshless) 2018-11-21

d.o. page

Only loads the parts of page that change when navigating between pages.

Unclear if still being maintained (no updates since Sep 2016) - part of the issue is it requires a core patch.

Telephone (telephone) 2017-02-08

d.o. page

Telephone number field type.  This is in core, but you need to enable it.

Field Permissions (field_permissions) 2018-11-21

d.o. page

"Essential"

Control editing/visibility of individual fields by role.  

As well as custom settings ('create own', 'edit own', 'view own', 'edit any' and 'view any' - all per role), there's a Private setting which gives access to the author and administrator only. 

These are automatically applied to views.

Finding the setting: Look for  Field visibility and permissions – on the Edit tab, NOT Field Settings.

In /admin/people/permissions there's also a Access other users private fields permission.

Bamboo Twig (bamboo_twig) 2018-11-19

d.o. page

Way to embed lots of objects in twig. note you have to selectively enable various sub modules for each of the commands.  Seems pretty actively developed and well documented.

ClamAV (clamav) 2018-11-20

d.o. page

"Essential"

Virus check files uploaded by users.

In Drupal - when it can't connect you get an error on the Status Report.
The status report also shows you the version which includes the virus signature info.
As soon as it can that error goes away.

There's a "verbose" option in the config settings (which logs files that "passed" the virus check as well as failed)

You need to tick 'Enable ClamAV integration' before it will actually scan any files.

Test it's working by creating a small file with the short Eicar test signature string

Notes: ClamAV does use a fair bit of memory (because it keeps a copy of all the virus signatures)

Also sensible to run a Nagios NRPE check to ensure ClamAV is always running.

Patch:

Requires core patch to avoid possible data loss (race condition) - use my rerolled patch (#35) 

Menu Token (menu_token) 2018-11-21

d.o. page

Add tokens, such as a user ID, to text or URL paths of menu items. 

Be wary of this issue: Current-user:uid not correct

CKEditor Wordcount (ckwordcount) 2018-12-06

d.o. page

Adds word/character/paragraph count to the CKEditor status bar (can optionally enforce a word/character limit)

Configured via Text formats and Editors (/admin/config/content/formats).

Requires the ckeditor wordcount library - example composer.json for that (put this in your 'repositories' section):

        "ckeditor.wordcount": {
            "type": "package",
            "package": {
                "name": "ckeditor/wordcount",
                "version": "1.17.4",
                "type": "drupal-library",
                "extra": {
                    "installer-name": "wordcount"
                },
                "dist": {
                    "url": "https://download.ckeditor.com/wordcount/releases/wordcount_1.17.4.zip",
                    "type": "zip"
                },
                "require": {
                    "composer/installers": "~1.0"
                }
            }
        },

and then require:

"ckeditor/wordcount": "1.17.4",

Patch needed:

https://www.drupal.org/files/issues/2018-12-06/ckwordcount_plugin_path_2850845-9.patch

(to ensure modules gives browser correct path of plugin.js - if your ckeditor input disappears, check console.log and it's probably that)

The notification module is a dependency.

Save edit (save_edit) 2019-12-21

d.o. page

"Essential"

Add a save and edit button

  • Needed(?) patchto ignore the ?destination=querystring on admin page. 
  • Integrated dropbutton doesn't seem to style correctly, turn this off.
AudioField (audiofield) 2021-09-02

d.o. page

"Essential"

This is a formatter, available on node display or in views.

It turns a uploaded file or an external URL into an HTML5 audio player. Also supports various other JS player libraries which you can download. You can turn lazy-loading of the file on or off.

Note: there is a default label added below the player, which is either the URL field description or actual address, if the former is missing. Override the audioplayer.html.twig template to remove this.

TagCloud (tagclouds) 2017-02-20

d.o. page

Provides a block with a tag cloud of chosen taxonomy term. Works but a bit buggy, e.g. UI taxonomy setting reverts to 'tags'.  Requires clearing the cache to update (including changing any settings).  Choice of numbers after each tag to indicate quality, or 'wordcloud' style with varying sizes (will need you to modify your CSS to add some spacing between words). 

Trash (trash) 2018-11-22

d.o. page

Adds a trash bin for all content, so you may later restore (or permanently delete) it.  Depends on Content Moderation module.  Alpha in D8.

Advanced Page Expiration (ape) 2018-09-17

d.o. page

Not recommended

I would avoid this.  The idea is you enter URL paths with wildcards and override the cache expiration.  I was unable to get it to work properly for pages (settings on config under Development > Performance) Also, re: caching images, those are files being served directly by Apache or Nginx, not via the Drupal front-controller, so caching settings need to be configured there.

Views Secondary Row (views_secondary_row) 2018-11-19

d.o. page

"Essential"

For Views that use Table format. Adds a row underneath each record - you change the format from 'table' to the 'secondary row' option, you get an extra select dropdown in the table *settings*, and you can also specify colspan.  This does mean the label will be missing by default (you won't have a column header any more) - so you need to edit the field and tick rewrite output, and then specify your desired label, followed by the field value in Twig.
 

Views exposed form layout (vefl) 2018-11-21

d.o. page

Not recommended

Layouts for exposed filters - i.e. you can move each filter into a region (supports Panels and Display Suite).

When I tried this (Summer 2018) the D8 branch wasn't really there yet - you could only rearrange the basic filter components in D8 (like search term, submit button, reset button), not all the extra ones you've added.   I went with using CSS (e.g. clear: both) instead.

Honeypot (honeypot) 2020-03-02

d.o. page

"Essential"

Adds spam prevention to forms (you can select which, including user registration and contact).

Recommended settings:

- turn logging on (look for entries of type = honeypot in /admin/reports/dblog
- if using time limit - i.e the minimum amount of time form is expected to be on screen before module things it's a real person, not a bot, suggest 5 seconds rather than 10 (too agressive when using browser autocomplete for, for example, email address on password reminder form)

Ngrok for drupal (ngrok_drupal) 2019-12-21

d.o. page

Sets the cookie domain correctly if you're using ngrok.

Use this if you have an Ngrok secure tunnel - e.g. if you are testing a Stripe Apple Pay integration (needs to run with a valid, publicly accessible SSH domain)

Redirect after login (redirect_after_login) 2021-12-01

d.o. page

"Essential"

Sends users (depending on their role) to another page, rather than their profile, immediately after logging in.

There's a bug (patch available, fortunately) with this which will break session cookies in Drupal 9, and upgrade_status doesn't warn you about it. 

Exclude Node Title (exclude_node_title) 2017-02-06

d.o. page

There are situations where you will want to hide a node title - e.g. if you have a view and insert an image field that's an entity reference to another content type.  Module allows you to hide titles by content type or view mode and for all nodes or just a custom selection.  Beta in D8.

Twig Xdebug (twig_xdebug) 2017-02-08

d.o. page

Use Xdebug breakpoints in Twig templates - {{ breakpoint() }}

Redirect (redirect) 2017-02-20

d.o. page

"Essential"

Add redirects, including specifying from the full range of HTTP codes (e.g 307 Temporary).  Won't let you redirect from the homepage, use Config > Basic Site Settings for that.

Webform (webform) 2020-02-09

d.o. page

"Essential"

One of the best maintained contrib modules.  Main benefits: nicely presented forms with powerful conditional logic, YAML configuration, flexible user permissions, very clean data storage, secure.  Codebase is also very much written "the Drupal way".

I'm currently using this patch to avoid AJAX errors - it's only necessary where you've both enabled Automatically save as draft when paging, previewing, and when there are validation errors, and are using a confirmation type like inline, that still uses AJAX to submit the form when there are no validation errors.

Troubleshooting install of webform external libraries: (Jan 2020)

Follow these instructions: https://www.drupal.org/node/3003140

If you get a composer SSL error, follow these instructions.

(specifically, you need to set openssl.cafile in php.ini)

SMTP Authentication Support (smtp) 2018-11-20

d.o. page

"Essential"

Send mail to a remote SMTP server (e.g. a transactional email provider like Postmark).  

You should put your authentication details in settings.php, rather than files you commit to the repo, for security.  

To get this to work - it was sending tests but nothing else - it seemed I needed to switch to a commit on the dev branch:

"drupal/smtp": "dev-1.x#3d354b3911409c9b11716bf2104498fb431eea72"

(note to self: see SM notes) 
 

Entity Embed (entity_embed) 2018-11-21

d.o. page

Lets you insert any entity type (supposedly) via the WYSIWYG editor, and like images you can set alignment etc.  It creates a toolbar button that can be added to the toolbar configuration in 'Text formats and editors'.  The strings needed can be pretty long - e.g. 

<drupal-entity data-embed-button="snippet" data-entity-embed-display="entity_reference:entity_reference_entity_id" data-entity-type="snippet" data-entity-uuid="216914ab-1bc2-4a73-975b-dc1de79e849a"></drupal-entity>
 

CKEditor Custom Config (ckeditor_config) 2018-12-06

d.o. page

I've not actually used this but I adapted it's code to enforce a configuration setting (I wanted to remove the HTML dom elements that are shown in the status bar).

The module allows you to supply your configuration using the UI.

Twig VarDumper (twig_vardumper) 2019-12-30

d.o. page

"Essential"

Much faster than using kint, with colour coding, and still works nicely within narrow DOM elements.
Make sure you install using composer, as it has symfony dependencies.

Enabling twig debugging in the first place:

Also make sure you've activated twig debugging properly (including enabling the settings.local.php file in settings.php, and adding the debug setting to development.services.yml)
Potential gotcha - settings.local.php needs to be in /sites/default (or whichever), not just /sites/
If Twig debugging isn't enabled, the symptom is you don't see any output for the dump() commands.

Usage Tip:

- Hover over the keys and you get a tooltip that says 'Public method','Protected property' etc.

Flippy (flippy) 2017-02-06

d.o. page

Add Next/previous links to node view for specific content types - e.g. image gallery.  Powerful - supports: next/last, random link, you can specify exact text used etc.  Currently a dev version in D8.

Setup: activate for a content type in the 'Edit' tab (NOT manage display). Once Flippy is active, Manage Display tab will have a pager field so you can reposition the links relative to other fields on the page (e.g. above or below image).
