WordPress vs. Drupal 8 ComparisonTesting with CiviCRM 5.15.0, Drupal 8.7.4 Drupal's.htaccess file prevents apache from directly calling scripts except in specific directories. So, for example, CiviMail links. Browse other questions tagged webform-civicrm drupal-8 or ask your own question. The Overflow Blog Podcast 332: Non-fungible Talking. The Loop: Our Community & Public Platform Roadmap for Q2 2021. Featured on Meta Stack Overflow for Teams is now free for up to 50 users, forever. Hat-tip to the CiviCRM Entity folks (Mark, Karin, David S, Luke, Matt G, and others) for the Drupal8 Views integration, as well as to helpful support from the folks in the Drupal mattermost channel. Drupal is a free and open source content-management framework written in PHP and distributed under the GNU General Public License, providing a back-end framework for among the largest sites on the internet, ranging from personal blogs to corporate, political, and government sites. The standard release of Drupal contains basic features common to content-management systems including user.
This page is intended to weigh the pros/cons between WordPress and Drupal 8. Everyone has their own preferences, however please consider our overhaul objectives when assessing the two platforms and not merely base input on a specific CMS preference. 
Cost evaluation: 
Pros:
Easier upgrade path than completely changing the CMS (content migration, images/assets, user accounts).
Provides a more robust content editing experience than Drupal 7, and support for Gutenberg is complete or near completion.
We rely on Views for many types of listings linked to CiviCRM.
Immediate costs to migrate appear to be relatively low.
Cons:
Drupal 10 will probably be another big upgrade. Should we bite the bullet and switch to a CMS that provides easier upgrades?
Drupal is not as popular as it used to be (the same could probably be said of WP, except that WP is more popular, but same growth rate).
Any improvements made will support Drupal 8 functionality parity with Drupal 7.
Long term maintenance costs are significant.
Cost evaluation: TODO
Pros:
Larger community, more options for page layouts, extensions, etc.
Easier to use from a content perspective, built-in Gutenberg support, several mature page builders.
Lower ongoing upgrade costs and lower longer term maintenance costs.
Any improvements made will support Wordpress functionality parity with Drupal.
Cons:
We will need WP developers to help porting over our custom code.
No 'Views' integration with CiviCRM. There are not that many, but it is probably the biggest argument against WordPress.
Content migration may be more difficult (though tools do exist that may make this a non-issue)
Higher security risk. Will likely need different measures in place.
Civicrm Drupal 8 UserAbout this documentThis guide covers standard installation of CiviCRM on an existing Drupal 8 or 9 site. It assumes that you previously completed these tasks:
Install Drupal 8or 9, and..
Alternative: Civibuild for developersIf you plan to develop patches for CiviCRM on Drupal 8 or 9, then please read the Developer Guide for information about Buildkit and civibuild.
Get the code¶

Drupal 8 (D8) and Drupal 9 (D9) sites are typically administered with Composer. Composer is a dependency management tool which can add, upgrade, and remove software packages for your site.
CiviCRM is published as a suite of related packages. Our goal is to use Composer to add CiviCRM's packages to the D8 site.
If you do not work regularly with Drupal 8 or 9 and Composer, then you should take a refresher before installing CiviCRM.
Quick and dirty introduction to Drupal 8 or 9 with composerComposer requires shell access to the D8/D9 site. It defines a command composer.
Many D8/D9 sites are initialized via composer, which means that composer is already available. Thiscan be confirmed in the shell by running composer --version:
It is possible that your system does not have composer -- for example, if you used a tar-based installation of D8,then you may never have needed composer before.
If composer is missing, then you must download and install it first.Additionally, you probably need to set composer's memory limithigh enough for D8/D9.
Once you have composer, you need to navigate to the composer-root. You can recognize it by the following:
It has the files composer.json and composer.lock.
It has a subfolder vendor/.
It usually has a subfolder web/ (the web-root); alternatively, it may be the web-root.
A typical file-hierarchy might look like:
To work with composer and D8/D9, you must open a shell and navigate to the composer-root, e.g.
Note: Drupal 9 and CiviCRM combinations require use of Composer 2.x.x
If composer is properly installed, then these example commands will add CiviCRM to D8 or D9:
You should adjust the example path (/var/www/drupal.example.org) and the example version (~5.35) as needed.
If you'd like more details to understand these commands or common errors, then please drill-down below.
More detail: Enable patchingFitness logo maker. A handful of packages used by CiviCRM require extra patch-files.
This is possible with the popular cweagans/composer-patchesplugin. However, you must opt-in to enable it.
More detail: Package stabilityFor any package in composer, there may be several available versions. Some have an official, well-defined nameor number (e.g. v1.2.3), and these are called 'stable' versions. Other versions have an interim name or number(e.g. v1.2.alpha1 or dev-master) indicating that additional testing is appropriate.
As a general rule, a new composer deployment will (and should) only use 'stable' versions. CiviCRM, too, isgenerally built around 'stable' dependencies. However, in some exceptional cases, CiviCRM requires an interimrelease of some libraries.
composer.json has two options which affect this: minimum-stability sets anabsolute baseline, and prefer-stable expresses a general preference.Setting minimum-stability to dev enables to installation to proceed when there are exceptional cases. Settingprefer-stable to true means that composer will use stable releases whenever it can.
More detail: Compilation tasksWhen you first install or upgrade to CiviCRM 5.31+, composer will prompt for permission to run CiviCRM compilation tasks. We recommend that you select [a]lways.
If you wish to suppress the prompt, see Composer Compile Plugin: Managing the root package (for site-builders).
More detail: Required packagesPackageDescription
civicrm/civicrm-asset-pluginA tool which automatically copies JS+CSS assets from CiviCRM to D8/D9's web/ folder
civicrm/civicrm-coreThe primary CiviCRM codebase
civicrm/civicrm-drupal-8The integration module for CiviCRM and D8/D9
civicrm/civicrm-packagesA collection of third-party/legacy packages used by CiviCRM
More detail: Version constraintsThe primary CiviCRM packages (civicrm-core, civicrm-drupal-8, civicrm-packages) have synchronizedversions. If one package is installed with v5.35, then the others should also be v5.35.
The following expression references the three packages and applies the same version-constraint to each:
The expression ~5.35 is a version-constraint. It means that composer will install approximately v5.35. It mayinstall a newer patch-release (e.g. 5.35.1) or a newer minor-release (e.g. 5.36.0). However, it will avoidmajor-releases (e.g. 6.0.0).
Many composer tutorials rely on composer to automatically choose package-versions.This is not recommended for CiviCRM and Drupal 8/9. Instead, package versioning should be explicit to ensure that:
CiviCRM versions remain synchronized.
CiviCRM stable releases are preferred over developmental releases.
How to resolve conflicts in pear/exception?In some D8 configurations, you may see an error message about the package pear/exception. This isbecause some packages use pear/exception -- but they have been overly specific about the requiredversion. (To wit: they require version 1.0.0 when version 1.0.1 will also work.)
To resolve this error, you can install v1.0.1 and pretend that it is v1.0.0:
After fixing this, you may continue the regular installation commands.
Get the translations¶I18n & L10n on Drupal 8 or 9
If installing with the GUI it is currently only possible to install CiviCRM in English (US) on Drupal 8/9. Adding the language files involves breaking with Composer best practices by writing the contents of the civicrm-l10n tarball into vendor/civicrm/civicrm-core or configuring the civicrm.l10n directory path after you install and placing the contents of the civicrm-l10n tarball into the configured directory.

Find album reviews, stream songs, credits and award information for Offenbach: The Tales of Hoffmann - London Symphony Orchestra, Julius Rudel, Beverly Sills on AllMusic - 2002.  The tenor starring in Offenbach's Tales of Hoffmann impersonates an historical figure, Ernst Theodor Amadeus Hoffmann. (Left, Hoffmann's own drawing of himself.) One of the most important German Romantics, Hoffmann was a lawyer, a painter, a composer and conductor, a music critic, and one of the world's great writers. Jacques Offenbach opera, Les Contes d'Hoffmann (The Tales of Hoffmann), remained unfinished at his death. It was orchestrated and provided with recitatives by Ernest Guiraud, who also introduced the famous barcarolle taken from Die Rheinnixen.
Here Be Dragons..
The following steps are provided as an example - they are not supported or widely tested and may leave your site in a broken state. You use them at your own risk. No. Seriously..
You will also have to repeat these steps every time you upgrade CiviCRM.
Civicrm Drupal 8 DownloadThe warnings above notwithstanding to install CiviCRM on Drupal 8/9 requires the following additional steps to prepare:
Add cv to your Drupal 8/9 Site with: composer require civicrm/cv (composer installs of cv are currently broken for now use the manual install steps.)
Grab the localisation (l10n) files and unpack the l10n and sql subfolders into vendor/civicrm/civicrm-core/
You'll find the l10n files on the CiviCRM Download page or from https://download.civicrm.org/civicrm-VERSION-l10n.tar.gz where VERSION is a recent version of CiviCRM.
Example:
If you've done this correctly, you should end up with vendor/civicrm/civicrm-core/l10n and vendor/civicrm/civicrm-core/sql/
You can remove any languages you don't need by deleting them before copying the l10n and sql folders.
Now we move onto Installing CiviCRM - Command line install
Run the installer¶Civicrm Drupal 8 ViewsThe installer verifies requirements, prepares the database, and initializes the configuration file. You may run the installer through the web interface (which is simpler) or the command-line interface (which has more options).
Run installer via Drupal 8/9 web UIInstallation options are very limitedCivicrm Drupal 8 FormCurrently there is no interactive installer for CiviCRM on Drupal 8/9, so the installer uses a firm set of defaults, e.g.
English Language Data: It only installs data for US English. It cannot install data for other languages.
Shared Database: It only uses the shared CMS database. It cannot use a separate MySQL database for CiviCRM.
No Sample Data: It only installs an empty, baseline dataset. It cannot install sample data.
If you need to configure any of these options, then use the command-line installer.
Write permissionsIt is critical that your web-server user is able to write to the web/sites/default/ directory in order to create civicrm.settings.php and that you have an appropriate value for execution time(s) and memory limit(s) as any interruption to the installer can (and will) result in an unusable install and require remedial steps to correct or a full reinstall! By default on Drupal 8.8+ this directory path is not writable by default, before installing you should ensure you grant write access to your web server user. With, e.g: sudo chmod u+w web/sites/default.
For multisite installations you'll also need to ensure your web server user has write access to additional sites e.g: sudo chmod u+w web/sites/site2.example.org.
Login to your Drupal site with administrator permissions.
Navigate to Manage >> Extend or point your web browser to the following URL:
https://example.org/admin/modules/
Find 'CiviCRM Core' and enable it (you can optionally enable 'CiviCRM Theme' to set a theme just for CiviCRM.)
At the bottom, click 'Install'. (Note: This may take a few moments to execute.)

At the bottom, click 'Install'. (Note: This may take a few moments to execute.)
Run installer via command-lineCiviCRM has a command-line administration tool, cv, which can perform installation. For details, see command-line installer.
Review the permissions¶Drupal will create the /files/ directory (and make it writeable), but only when saving admin/settings. Same holds for /temp directory, and a /uploads/ directory in the CiviCRM module root. On a brand-new Drupal install, this directory may be missing. Even on an existing installation, if file permissions are not set properly, the directory may be missing. If enabling the CiviCRM module generates errors regarding the files directory, you must create it (writeable) manually.
Go to the CiviCRM dashboard to see the CiviCRM menus:https://example.org/civicrm (or https://example.org/index.php?q=civicrm if you don't have Clean URLs enabled)
Go to Administer » User management » Permissions
Verify that the Roles that you want to have access to CiviCRM have the appropriate permissions checked. CiviCRM is installed with a number of fixed permissions (such as 'edit contacts' and 'administer CiviCRM').
Permissions for the Anonymous Role
Many sites want anonymous visitors to have access to certain CiviCRM functionality. These permissions are enabled during installation for the Anonymous role. You should review them and modify if needed based on your requirements:
access all custom data : If you plan on collecting 'custom' data from visitors in standalone forms or as they make a contribution - enable this permission.
access CiviMail subscribe/unsubscribe pages : If you are planning on using CiviMail, enable this permission to allow anonymous users to subscribe and unsubscribe from mailing lists via the web.
access uploaded files : If you plan on allowing visitors to upload or view photos or other files - enable this permission.
make online contributions : If you plan on soliciting online contributions from visitors, enable this permission for the 'anonymous' role.
profile listings and forms : If you plan on collecting name and address or other information from visitors, enable this permission for the 'anonymous' role.
view event info and register for events : If you plan to use CiviEvent and want to allow un-authenticated visitors to view event information and register for events online - enable these permissions for the 'anonymous' role.
view event participants : Enable this permission to allow anonymous users to access participant listing pages for events.
Synchronize the users¶Once installed, CiviCRM keeps your Drupal Users synchronized with corresponding CiviCRM contact records. The 'rule' is that there will be a matched contact record for each Drupal user record. Conversely, only contacts who are authenticated users of your site will have corresponding Drupal user records.
When CiviCRM is installed on top of an existing Drupal site, a special CiviCRM Administrative feature allows you to automatically create CiviCRM contacts for all existing Drupal users:
Login to your Drupal site with an administrator-level login
Click the CiviCRM link in the main navigation block
If your Drupal site makes use of the db_prefix setting (in settings.php), in the top bar click Administer » System Settings » CMS Database Integration , and update the box for the Drupal Users Table Name so that it includes the prefix.
Click Administer in the menu bar
Click Users and Permissions from the drop-down menu, then select Synchronize Users to Contacts
Review the checklist¶The Configuration Checklist provides a convenient way to work through the settings that need to be reviewed and configured for a new site. You can link to this checklist from the installation success page and you can visit it at any time from Administer » Administration Console » Configuration Checklist.
Test-drive CiviCRM¶There should now be a CiviCRM link in your Drupal menu. Click that link and the CiviCRM Menu, Shortcuts, Search and New Individual Blocks should appear. You can now explore CiviCRM end-user features and begin configuring CiviCRM for your site/organization needs.
Addenda¶TLS for MySQL¶If your MySQL database is hosted on a different machine than your web server, or if your host requires it, you can use TLS to encrypt the connection between the database and the web server.
Full instructions on installing drupal are out of scope for this guide, but one method is to install into a test database first without MySQL encryption and then move the database to the live server and update settings.php to enable MySQL encryption.
See TLS for MySQL for introductory concepts and the settings for the CiviCRM database. For the Drupal database you have several options for updating settings.php:
The simplest, which doesn't require a client certificate, but doesn't verify the server certificate.
Verifies the server certificate, and doesn't require a client certificate.
Host name must match certificate name
Note that the DATABASE SERVER certificate would have to have a CN (common name field) that matches exactly the host you are using in $databases['default']['default']['host']. So if the host is db435.examplehost.com, then that must be the name on the SERVER certificate.
Client certificate/key pair (not self-signed), and do not verify the server certificate.
Client certificate/key pair (could be self-signed), and verify the server certificate.
