CentOS 8 - compatible with SCHLIX CMS v2.2.x

CentOS 8 has just been released yesterday. We've tested it and the new SCHLIX CMS v2.2.x series works out of the box (including with the new MySQL 8.0) with only minimal changes to the default configuration. Check out the CentOS 8 LAMP server installation guide for SCHLIX CMS.

Extension Gallery - a marketplace for web design agencies/freelance PHP developers

In mid-October, we will release a new SCHLIX CMS version 2.2.1-x with a new marketplace integration application called Extension Gallery. With the new Extension Gallery, website owner can easily install/uninstall extension without having to download a ZIP file manually from our current Extension Gallery. If you're a PHP web agency or a PHP freelance developer, you can submit a SCHLIX CMS plugin (application/block/macro) and get more exposure. It's free and this is a great opportunity to showcase your solutions. Both commercial and open source extensions are accepted.

The extension submission process is already open and we're hoping to get more developers to use SCHLIX CMS.

New 2.2.x series - SCHLIX CMS v2.2.0-1 has been released

SCHLIX CMS v2.2.0-1 has been released, marking the new v2.2.x series. It is considered a significant change from the previous v2.1.x series as many internals have been updated. The 2.2.x is a transitional release, ensuring backward compatibilities with earlier version of plugins developed for SCHLIX CMS.

Highlight of new features

Custom header image

Previously, designers had to rely on using either a macro or a custom code to insert an expanded banner/header image above the content. This was cumbersome as a slight change to the HTML code means that the content items need to be updated individually. In the new v2.2.x series, they can do it easily by simply choosing to upload a custom media header and any change to the HTML tag can simply be performed in the template itself. Please have a look at the code comments inside the newly included companyprofile theme.

Custom header banner image

The following is a screenshot of the editor page where you can easily change the header image. You can configure the width, height and quality from Settings - Custom Header.

Sample header image

To enable this feature in your own application, simply specify the following code in the constructor:

$this->has_versioning = true;

Spell Checker

We have added a spell checker functionality.

Spell Checker

It's still in BETA mode, so you will have to manually enable it from Settings - Editor Manager.

TinyMCE 4 Spell Checker

Custom Field

You can now specify a custom field to be used in many applications. This is useful when you need to add a field to a contact form, etc. We're currently still testing this feature and will enable this feature on other applications as well. Please note that all custom fields will have the xcf_ prefix in the actual database. In your view template, you can simply output it manually. For example:

<?php $custom_fields = $this->getItemCustomFields(); ?>
<?php foreach ($custom_fields as $cf): ?>
<?php $field_name = 'xcf_'.$cf['field_name']; $field_label = $cf['field_label'] ?>
<div class="contacts_info_label custom_field">
   <i class="fa fa-file"></i>
   <?= ___h($item[$field_name]); ?>

To enable this feature in your own application, simply specify the following code in your view.admin.template.php file:

<x-ui:schlix-explorer-menu-command data-schlix-command="custom-table-config" data-custom-table="gk_contact_items" fonticon="fas fa-terminal" label="<?= ___('Custom table fields: Contact') ?>" />

<x-ui:schlix-explorer-menu-command data-schlix-command="custom-table-config" data-custom-table="gk_contact_messages"  fonticon="fas fa-terminal" label="<?= ___('Custom table fields: Messages') ?>" />

Custom Field 1

Custom Field 2

Custom Field 3


You can now extend an application functionality from another class (e.g. on the custom field function). Simply create a function with hook_ prefix and it will be executed.

Hook example

To create an application that calls a hook function, simply call \SCHLIX\cmsHooks::execute( ... ). We will write a documentation on this later.

X-UI tags

We have now switched to a framework-independent X-UI tag to future-proof our CMS. We used to heavily depend on Bootstrap 3, but as we realized

 <x-ui:schlix-multi-source-media-uploader data-field="url_media_file" name="image_file" id="image_file" data-dir-key="image_medium" accept="image/png, image/jpeg, image/gif" data-disable-option-existing-file="true" data-disable-option-none="true" data-allow-url-variable-dimension="true" data-preview-width="<?= $preview_width ?>" data-preview-height="<?= $preview_height ?>" />

Simple examples:

<x-ui:textbox id="meta_description" name="meta_description"  data-field="meta_description" label="<?= ___('Meta Description') ?>" />

<x-ui:schlix-tab id="tab_content" fonticon="far fa-file-alt" label="<?= ___('Content') ?>">
 Tab content

GDPR (Personal Data Request)

We have provided basic functionality for user data request. This application is disabled by default upon installation & upgrade.


  • Additional 6 new languages (Georgian, Kazakh, Mongolian, Arabic, Hebrew, Persian) have been added.
  • You can now change the theme colour of the backend. This is useful especially if you need to open different SCHLIX CMS sites.
  • You can specify whether the frontend uses Bootstrap 3 or 4. We will also expand the functionality to include other CSS frameworks such as Bulma and Zurb Foundation.
  • If you need your site to be online but invisible to the search engine during the development, you can specify its visiblity as hidden and turn it back on when needed.

Backward incompatible changes

If you have installed an application and you have the following lines in the *.admin.class.php onModifyDataBeforeSaveItem or onModifyDataBeforeSaveCategory, please either comment it out or simply delete them. You have until the end of December 2021 before this backward compatibility is removed.

/* NO LONGER NEEDED AS OF 2.2.0 - please remove these lines completely or comment them out */
if ($datavalues['permission_read_everyone'])        
      $datavalues['permission_read'] = 'everyone';
      $datavalues['permission_read'] = serialize($datavalues['permission_read']);
 $datavalues['permission_write'] = serialize($datavalues['permission_write']);

SCHLIX CMS v2.1.9-0 with a revamped admin interface

SCHLIX CMS v2.1.9-0 has been released. A couple of notable changes:

  • Revamped admin interface for better editing experience. Quite a few of our users have made a comment last year that the dark interface has made it harder to read and navigate on the backend. We've restored the original theme and provided a new styling as well. We will make the dark theme as a configurable option later.
  • Free map hosting for the Contacts application. If you are web design agency or even just a regular user who can't to pay hundreds of dollars of billing for Google Maps, we've replaced Google Maps with OpenStreetMap, hosted on our own tile server (, with CDN delivery to ensure fast browsing experience across different geographic regions. You don't need to enter Google Maps API key anymore in the Contacts application. Since this took quite some effort to implement, we've pushed back other features that we promised earlier. If you have any extensions that require mapping solution, you can use our server for free as long as your website is implemented with SCHLIX CMS and that the load requirement is reasonable.

SCHLIX CMS v2.1.9-0

If you have any questions, please post your question in the forum.

SCHLIX CMS v2.1.8-1 has been released

SCHLIX CMS v2.1.8-1 has been released. We have added a few new security features in this release. When you login to the backend, the system will perform the following checks:

  • Possible malicious users (only for sites with registration enabled) including their IP address.
  • Possible malicious files (e.g. PHP script uploaded to image folder)
  • List of all world writable files and directories

The system will then attempt to fix them automatically and the report can be downloaded from /web/[your-website-name]/data/private/quarantine. This folder is inaccessible from the user's browser and the content must be manually downloaded via SFTP or FTP.

Note - there's v2.1.8-2 release that fixed the false positives and System Updater user interface issue as the automated security check ran immediately after the upgrade and thus causing a JSON error. If you've upgraded to v2.1.8-1 and got an error message right after the upgrade, you can ignore that error.

SCHLIX CMS v2.1.8-0 has been released

SCHLIX CMS v2.1.8-0 has been released. This is a maintenance only release with the following changes:

  • Updated: JQuery 3.2.x to 3.3.1
  • Updated: Font Awesome 4.7 to 5.2.0 (free) with adblock compatiblity
  • Updated: TinyMCE 4.8.2
  • Updated: PHPMailer 6.0.5
  • Updated: Bootstrap 3 update (now compatible with JQuery 3.x). We're still working on Bootstrap 4 update
  • Fixed: Applications built derived from cmsApplication_Basic missing title during install
  • Fixed: Block instance configuration was being saved incorrectly if the title was not all in lowercase or contain non-ASCII characters
  • Fixed: Forgot password link on HTTPS website didn't display for the full URL
  • Fixed: Menu editor (backend) duplicate tree child item when clicking View a specific item/category
  • Fixed: Compatibilities with PHP 7.2
  • Enhancement: The method \SCHLIX\cmsPageOutput::HTMLHeader() can now be split into \SCHLIX\cmsPageOutput::HTMLHeaderNonScript() and \SCHLIX\cmsPageOutput::HTMLFooterScripts(). See the samplemagazine theme for more info

We realized that we're a bit behind in terms of the promised e-commerce implementation. Please note that the following is still in the works: Google Maps replacement, UTF8MB4 conversion (currently still using UTF8), GDPR and new Google Analytics tag.

SCHLIX CMS 2.1.7 build #2 has been released

SCHLIX CMS v2.1.7 build #2 has been released today to fix some minor bugs:

  • Fixed: CSS on installer page
  • Fixed: Dropdown box CSS not visible on Chrome
  • Fixed: Slideshow ~ ensure data directory exists before upload
  • Fixed: Slideshow ~ drag and drop (1st item)
  • Fixed: Blog ~ drag and drop (1st item)
  • Fixed: Menu block ~ added block name in front of id (e.g. block_topnavigation_id-1) to handle a case where some themes use more than one block in one page
  • Enhancement: Frontend edit control now shows Options instead of just icons for better visibility

SCHLIX CMS 2.1.7 released with new look and feel

SCHLIX CMS v2.1.7 (build #1) has been released today. The base theme has been changed to dark by default, inspired by KDE's Dark Breeze and Ubuntu's Unity theme. The light theme will still be available as a separate download at the end of December 2017 (or maybe January 2018) and you can customize it with your company logo. This will be useful for web design agencies and freelancers out there. In addition to this, there is already a custom admin theme that you can download from the Themes directory.

Other important changes:

  • Fixed some of the Macedonian and Indonesian translations.
  • Fixed URL for content fragments for Landing Pages. The URL will be set to / instead of /lp if the frontend application is set to Landing Pages. If your frontend application is set to Web Pages (html), this will not affect you. For the change to take effect, you must manually edit the menu item from Menus and save it.
  • Enhancement: Contact form is now using fully AJAX so it can be inserted in the middle of the content.
  • New InsertContactForm macro to embed contact form in the middle of any content text
