@BernhardB & Marty
You can install the module via Soma's Modules Manager or download it manually and put it in the modules folder. This should work. I will try to fix installation with the 'Download and Install' option in PW.

1 hour later:

I could fix it. Should work now. Thank you for reporting.

Thank you for this module - I don't know how I managed to overlook it until now. It should come in very useful.

Is there any chance you could either add an option to allow the automatically generated filename to include the creation date, or move the filename generation into a hookable method so people can supply their own name generator if needed?

Regardless of the above request, thank you again!

K so I've now been using this module for 6 days and everything is working perfectly, lovin' it. So I guess the only thing that I would like is to be able to limit the amount of backups that this module creates and have that setting somewhere accessible either through a hard coded variable or the admin interface. I'm thinking just a delete function that is called when the latest backup is complete.  I'm going to take a look and see if that is something that I may be able to contribute.

I am working on this, but hadn't time to do. As a starting point this could help


$path = "/home/yoursite/backups"; // full server path to the directory where you want the backup files (no trailing slash)

$hrs = 3600;
$days = 24 * $hrs;

$todaysdate = date('Ymd', time());

// Live Site Cutoff
$livecutoff = date('Ymd', (time() - (7*$days)));

$target = $path . "/site/" . $todaysdate . ".tar.gz";

$filelist = scandir($path . "/site");
foreach ($filelist as $backupfile) {
	if (stristr($backupfile, ".tar.gz")) {
		$filedate = explode('.tar.gz', $backupfile);
		if ($filedate[0] < $livecutoff) {
			unlink($path . "/site/" . $backupfile);

system("tar --create --preserve --gzip  --file=".$target." ~/public_html ~/mail ~/ftpconf",$result);
$size = filesize($target);
switch ($size) {
  case ($size>=1048576): $size = round($size/1048576) . " MB"; break;
  case ($size>=1024);    $size = round($size/1024) . " KB"; break;
  default:               $size = $size . " bytes"; break;

This is just a snippet for a first approach, nothing to use as is.

are you planning to add this kind of functionality to your module some day? any planned date for this?

i'm just curious. no real need for me right now because i'm using plesks backup feature. i was just wondering because the database is just one part of the whole...

nothing planned. I think this feature could be useful in case of providing file uploads for frontenduser or so. Until now I have no need for this feature. Maybe tomorrow ... :rolleyes:

as I said no need for me now. All assets I have to deal with are stored on my or my customers local machine. But you are right in case of file upload option for visitors file backup is a must.

but how do you handle situations like when somebody deletes some files, then you restore a DB backup and the files referenced in the file-field are not stored in the filesystem any more?

good question. For all file backups I rely on a combination of my daily\weekly\monthly backups through whm, I don't allow users to empty the trash and use the trashman module to allow users to restore any accidentally trashed files instead. I find that really clamping down on user permissions cuts down on these worries.

I have upgraded PW to the latest dev version (21) and now I get the following error if I want to open a backup:

Error: Exception: Unknown Selector operator: '' -- was your selector value properly escaped? (in /home/.sites/24/site1275/web/wire/core/Selectors.php line 283)

#8 /home/.sites/24/site1275/web/wire/core/Pages.php(320): Pages->find('0:7232549db11.s...', Array)

I dont know if the error exist only after the last upgrade or if it occured earlier.

What does this error message means?

Thanks for reporting. You cannot open or restoring a backup from CronjobDatabaseModule but in ProcessDatabaseBackups which is a module made by Ryan. I couldn't  reproduce your error in PW 2.6.21. You maybe could post a new topic in general support forum. Some more information would be helpful: is CronjobDatabaseBackup still doing its job? Could you try to restore from a backup created in the 2.6.21 environment? Thanks.

      This module lets you add some custom menu items to the main admin menu, and you can set the dropdown links dynamically in a hook if needed.
      Sidenote: the module config uses some repeatable/sortable rows for the child link settings, similar to the ProFields Table interface. The data gets saved as JSON in a hidden textarea field. Might be interesting to other module developers?
      Custom Admin Menus
      Adds up to three custom menu items with optional dropdowns to the main admin menu.
      The menu items can link to admin pages, front-end pages, or pages on external websites.
      The links can be set to open in a new browser tab, and child links in the dropdown can be given an icon.
      Requires ProcessWire v3.0.178 or newer.
      Example of menu items

      Module config for the menus

      Link list shown when parent menu item is not given a URL

      Setting child menu items dynamically
      If needed you can set the child menu items dynamically using a hook.
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); if($menu_number === 1) { $colours = $event->wire()->pages->findRaw('template=colour', ['title', 'url', 'page_icon']); $children = []; foreach($colours as $colour) { // Each child item should be an array with the following keys $children[] = [ 'icon' => $colour['page_icon'], 'label' => $colour['title'], 'url' => $colour['url'], 'newtab' => false, ]; } $event->return = $children; } }); Create multiple levels of flyout menus
      It's also possible to create multiple levels of flyout submenus using a hook.

      For each level a submenu can be defined in a "children" item. Example:
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); if($menu_number === 1) { $children = [ [ 'icon' => 'adjust', 'label' => 'One', 'url' => '/one/', 'newtab' => false, ], [ 'icon' => 'anchor', 'label' => 'Two', 'url' => '/two/', 'newtab' => false, 'children' => [ [ 'icon' => 'child', 'label' => 'Red', 'url' => '/red/', 'newtab' => false, ], [ 'icon' => 'bullhorn', 'label' => 'Green', 'url' => '/green/', 'newtab' => false, 'children' => [ [ 'icon' => 'wifi', 'label' => 'Small', 'url' => '/small/', 'newtab' => true, ], [ 'icon' => 'codepen', 'label' => 'Medium', 'url' => '/medium/', 'newtab' => false, ], [ 'icon' => 'cogs', 'label' => 'Large', 'url' => '/large/', 'newtab' => false, ], ] ], [ 'icon' => 'futbol-o', 'label' => 'Blue', 'url' => '/blue/', 'newtab' => true, ], ] ], [ 'icon' => 'hand-o-left', 'label' => 'Three', 'url' => '/three/', 'newtab' => false, ], ]; $event->return = $children; } }); Showing/hiding menus according to user role
      You can determine which menu items can be seen by a role by checking the user's role in the hook.
      For example, if a user has or lacks a role you could include different child menu items in the hook return value. Or if you want to conditionally hide a custom menu altogether you can set the return value to false. Example:
      $wire->addHookAfter('CustomAdminMenus::getMenuChildren', function(HookEvent $event) { // The menu number is the first argument $menu_number = $event->arguments(0); $user = $event->wire()->user; // For custom menu number 1... if($menu_number === 1) { // ...if user does not have some particular role... if(!$user->hasRole('foo')) { // ...do not show the menu $event->return = false; } } });

      Symprowire is a PHP MVC Framework based and built on Symfony using ProcessWire 3.x as DBAL and Service-Provider
      It acts as a Drop-In Replacement Module to handle the Request/Response outside the ProcessWire Admin. Even tough Symfony or any other mature MVC Framework could be intimidating at first, Symprowire tries to abstract Configuration and Symfony Internals away as much as possible to give you a quick start and lift the heavy work for you.
      The main Goal is to give an easy path to follow an MVC Approach during development with ProcessWire and open up the available eco-system.
      You can find the GitHub Repo and more Information here: https://github.com/Luis85/symprowire
      The Symprowire Wiki https://github.com/Luis85/symprowire/wiki How to create a simple Blog with Symprowire https://github.com/Luis85/symprowire/wiki/Symprowire-Blog-Tutorial Last Update
      16.07.2021 // RC 1 v0.6.0 centralized ProcessWire access trough out the Application by wrapping to a Service https://github.com/Luis85/symprowire/releases/tag/v0.6.0-rc-1 Requirements
      PHP ^7.4 Fresh ProcessWire ^3.0.181 with a Blank Profile Composer 2 (v1 should work, not recommended) The usual Symfony Requirements Features
      Twig Dependency Injection Monolog for Symprowire Support for .env YAML Configuration Symfony Console and Console Commands Symfony Webprofiler Full ProcessWire access inside your Controller and Services Webpack Encore support Caveats
      Symfony is no small Framework and will come with a price in terms of Memory Usage and added Overhead. To give you a taste I installed Tracy Debugger alongside to compare ProcessWire profiling with the included Symfony Webprofiler

      So in a fresh install Symprowire would atleast add another 2MB of Memory usage and around 40ms in response time, should be less in production due to the added overhead of the Webprofiler in dev env
