Column layouts

This feature builds on the recent improvements to the blocks/group handler and adds the ability to define column layouts for each content row when row=on is set.

To try it out, add the following to your layout template:

{! blocks/group?wildcard=[id]-*&rows=on !}

This tag turns a page into an expandable set of rows of content blocks, which can now also contain up to 5 columns of content.

You'll see a new Content Layout button next to the up/down arrows in the block edit buttons. The buttons in the first column now control the properties for the entire row, and each column now has its own edit button too.

When you click this new button, or when you click the Add Block button to add another row of content, you'll be shown the following options for content layouts:

The layout can also be modified through the block add/edit forms sidebar:

And finally, you can tab between the rows just above the wysiwyg editor, so you can edit an entire row from the same form:

Docker support

Elefant now includes Docker configurations for building production and development containers, as well as a docker-compose file for spinning up a complete development environment in a single command which includes a MySQL database and Redis-backed caching.

To build a production container from a fresh clone of the Elefant repository, run:

$ make build

This will build a container named elefant. Similarly, you can build a development container via:

$ make dev

This will build a container named elefant-dev.

To spin up a development environment (after running make dev), run:

$ make run

And to shut it down, run:

$ make down

Take a look at the included docker-compose.yml and .docker/* files for more info.

Other improvements

  • Added ELEFANT_DEFAULT_PASS environment variable for ./elefant install command line installer
  • When you change the ID of a page that uses blocks/group as shown above, Elefant will update the block IDs so they don't become unlinked from the page
  • You can now load scripts asynchronously via $page->add_script ('/apps/myapp/js/script.js', 'async')
  • Updated CSRF validation to use sha256 and to use separate expiring tokens per request URI

Introducing JobQueue

This update adds a new JobQueue class which is powered by Pheanstalk/Beanstalkd. This makes it very easy to setup background workers and send tasks to them for processing.

Setup

To set it up, install Beanstalkd via your package manager of choice (apt/yum/brew/port), for example:

$ apt install beanstalkd

Next, after upgrading Elefant to 2.2.4, run Composer update from the root directory of your website to install the Pheanstalk library:

$ cd /path/to/www && composer update

Lastly, edit the [JobQueue] settings in your conf/config.php file to point to your Beanstalkd server:

[JobQueue]

backend = beanstalkd
host = 127.0.0.1
port = 11300

Usage

Sending a job to be done by a background worker is as easy as:

JobQueue::enqueue ('tube-name', ['data' => '...']);

Writing a worker in Elefant looks like this:

<?php // apps/myapp/handlers/worker.php

if (! $this->cli) exit;

$page->layout = false;

$worker = JobQueue::worker ();

$worker->watch ('tube-name');

while ($job = $worker->reserve ()) {
    $data = json_decode ($job->getData ());

    // Process job with $data

    $worker->delete ($job);
}

The above worker can be run via php index.php myapp/worker and can be initialized using your system scheduler, such as systemd.

Note that workers can be written in any language that connects to Beanstalkd and listens for jobs to process.

Other improvements

  • Added User::require_verification() which extends User::require_login() to require email verification too
  • Added Auto-include Composer autoloader to Site Settings form so you no longer need to include it manually in a bootstrap.php file

Bug fixes

  • Fixed blog post slugs changing back to their default values
  • Fixed upgrades missing schema changes for in-between versions
  • Added $this->get_params() method to Restful for easier input parameter parsing and validation
  • Added ability to select from custom CSS styles for blocks/group rows 1
  • Marked all Elefant-related cookies with SameSite=Lax
  • Changed $cache->delete() to use unlink() for async deletions on newer versions of phpredis
  • Improved display and usability of tables in the wysiwyg editor
  • Fixed MySQL error at text field with default value
  • Fixed custom site styles affecting the Elefant toolbar heading colours and embedded button styles

1. The block editor first looks for a layouts/your-theme/blocks.css file, otherwise it reads all layouts/your-theme/*.css files, and finds all styles using the form .block-outer.custom-class-name. It then turns all unique custom classes found into selectable style options in a dropdown list.

Security update

Updated the Apache .htaccess settings and Nginx example configuration to more securely handle files uploaded through the file manager.

Note: Nginx users should copy the following new lines into their server{} block in their Nginx configuration and restart Nginx to apply the update:

location ~ ^/files/.*\.(?!(gif|jpe?g|png|mp4|pdf))$ {
	add_header Content-disposition "attachment";
}

It was also discovered that file extension limits weren't being verified when renaming files, which has been fixed too.

Search improvements

We've made some big improvements to the search bar for Web Pages, Blog Posts, and Accounts. This also affects Model::where_search(), improving other instances of it as well.

You can now use "quoted text" in searches to search for literal phrases that include spaces.

You can also use -word to omit words from your search. Combined, these improvements give users a lot more flexibility in how they can query their data.

Other improvements

  • Password recovery page can be overridden with a custom handler.
  • Added a new |absolutize template filter (usage: {url|absolutize}) to ensure URLs are absolute.
  • Added conf/envmap.php to map alternate environment variables and to Elefant's own.

Bug fixes

  • Fixed an issue deleting files.
  • Fixed empty searches in Model::where_search().
  • Fixed consistency of HMAC to prefer + instead of %20.
  • Fixed potential error in blog post parsing.
