ProcessWire Dashboard


Recommended Posts

@MarkE There's currently no direct way to do this — the chart data is passed as a JSON blob, so no functions. I've been looking at setting up charts via JS files or JSON endpoints, but nothing concrete yet. I'll probably end up moving the chart panel to a chartkick.js implementation which would allow all of that.

@d'Hinnisdaël - if you're contemplating moving away from chartjs, can I recommend a library that outputs SVG, rather than canvas - perhaps c3js? The reason being that it makes styling the charts with CSS really easy and also modifying them with D3JS is easy.

On a different note, I wonder if you'd consider setting up support for multiple tabs using WireTab? One of my dashboards is getting very long and it would be great to be able to split it up into different views and I think a tabbed interface would be effective.

Good point about making charts styleable via CSS. My experience has been that most clients and most dashboards don't need charts at all, so frankly I don't think I'll be investing too much time here, but if or when I decide to revamp the chart panel I'll keep that in mind.

Adding tabs is definitely on my list. Groups are already supported, so adding tabs should be somewhat trivial. There's possible performance issues to keep in mind when rendering too many panels at once but that shouldn't be a blocker.

@adrian I went ahead and added very basic tab support. Thanks for the nudge. If you want to give it a try, feel free to check out the tabs branch of the repo. Theoretically it supports nesting tabs inside groups and vice versa, however it's largely untested so let me know if you run into trouble. I'd like to do some more testing before releasing a new version.

wire()->addHookAfter('Dashboard::getPanels', function ($event) {
    $panels = $event->return;

    $tab1 = $panels->createTab(['title' => 'Lorem ipsum']);
    $tab1->add(/* add panels here */);

    $tab2 = $panels->createTab(['title' => 'Dolor sit amet']);
    $tab2->add(/* add panels here */);

    $panels->add($tab1);
    $panels->add($tab2);
});

I recently installed the Processwire Dashboard module (https://daun.github.io/processwire-dashboard/#/). After I added the hook code in site/templates/admin.php, even though I can see the dashboard, the 'Pages' page shows this error -

Fatal error: Cannot redeclare _checkForMaxInputVars() (previously declared in wire/core/admin.php:line 96).' 

When I try to add a panel to show the Pagelist or simply try to access the subpages of any parent page, I see this error too. This error disappears when I remove the hook code from sites/templates/admin.php file. The code that the Dashboard module suggests we add to this file is as follows:

wire()->addHookAfter('Dashboard::getPanels'function ($event) {
  /* Get list of panels */
  $panels = $event->return;
 
  /* Add panels */
  $panels->add([
    'panel' => 'collection',
    'title' => 'News items',
    'data' => [
      'collection' => 'template=news-item, limit=10',
      'sortable' => true,
    ],
  ]);
});
 
/* Make sure to add the hook *before* the default admin process */
require $config->paths->adminTemplates . 'controller.php';

Any suggestions on how to solve this?

Thanks.

      Hi guys!
      I'm a bit anxious because this is the first module I present! (beta modulo) But I will finally be able to share something with the community too! :)
      This is a BETA version of the PayPal payment system called: PayPal Commerce Platform.
      It is an advanced system (Business Pro account is needed) that brings various benefits in terms of fees and above all integrates direct payment with credit/debit cards. 
      The module integrates with Padloper 0.0.2, which is the current installation I'm using.
      This system integrates the classic PayPal buy button, the alternative or local payment method and the new payment system: credit/debit cards that doesn't go through the PayPal account. It is a Stripe-style payment, it connects directly with the bank and integrates 3D security validation.
      I say that it is a BETA because this module currently only works with Sandbox account, to put it live you need to change API url manually (manually for the moment).
      Because this module is not ready for live:
      I would like to have your opinion on how I built the module (is the first one I do). I don't want to share something that is not fish but I need a comparison with someone more experienced than me, for be sure that this is the best way to code the module.
      If you want to try this I created a git, you will find all the instructions for installation and correct operation. (Git has a MIT licensed)
      https://github.com/MarcooRo/processwire-PayPal-Commerce-Platform I hope I did something that you guys can like :)

      Hello Community!
      I found quite a  few ways or tools to style the admin or build a dashboard:
      - the new way with the .less compilation (reno style, rock style)
      - dashboard modules or tutorials how to build your own
      - admin on stereoids
      Vocabulary: With "admin like user" I do not mean a full admin but an user with quite a lot of priviledges ...
      My problem is that I do want to change the admin template for every (admin like) user in a different way. Or if I would build a bigger dashboard certain functionlity should only be available for a few (admin like) users but not for everyone.
      I would need different versions of the admin theme or the built dashboards for different admin users
      To start with a very simple example:
      Let's say I wanna give one (admin like) user a different background color (with css). 
      Let's say I wanna have an extra button or tab for some (admin like) user which another (admin like) user should not have
      How can I take advantage of processwire roles in all these examples I mentioned in the beginning?

      (once again I was surprised to see a work of mine pop up in the newsletter, this time without even listing the module on PW modules website 😅. Thx @teppo !)
      FieldtypeQRCode
      Github: https://github.com/romaincazier/FieldtypeQRCode
      Modules directory: https://processwire.com/modules/fieldtype-qrcode/
      A simple fieldtype generating a QR Code from the public URL of the page, and more.
      Using the PHP library QR Code Generator by Kazuhiko Arase.

      Options
      In the field’s Details tab you can change between .gif or .svg formats. If you select .svg you will have the option to directly output the markup instead of a base64 image. SVG is the default.
      You can also change what is used to generate the QR code and even have several sources. The accepted sources (separated by a comma) are: httpUrl, editUrl, or the name of any text/URL/file/image field.
      If LanguageSupport is installed the compatible sources (httpUrl, text field, ...) will return as many QR codes as there are languages. Note however that when outputting on the front-end, only the languages visible to the user will be generated.
      Formatting
      Unformatted value
      When using $page->getUnformatted("qrcode_field") it returns an array with the following structure:
      [ [ "label" => string, // label used in the admin "qr" => string, // the qrcode image "source" => string, // the source, as defined in the configuration "text" => string // and the text used to generate the qrcode ], ... ] Formatted value
      The formatted value is an <img>/<svg> (or several right next to each other). There is no other markup.
      Should you need the same markup as in the admin you could use:
      $field = $fields->get("qrcode_field"); $field->type->markupValue($page, $field, $page->getUnformatted("qrcode_field")); But it’s a bit cumbersome, plus you need to import the FieldtypeQRCode's css/js. Best is to make your own markup using the unformatted value.
      Static QR code generator
      You can call FieldtypeQRCode::generateQRCode to generate any QR code you want. Its arguments are:
      string $text bool $svg Generate the QR code as svg instead of gif ? (default=true) bool $markup If svg, output its markup instead of a base64 ? (default=false) Hooks
      Please have a look at the source code for more details about the hookable functions.
      Examples
      $wire->addHookAfter("FieldtypeQRCode::getQRText", function($event) { $page = $event->arguments("page"); $event->return = $page->title; // or could be: $event->return = "Your custom text"; }) $wire->addHookAfter("FieldtypeQRCode::generateQRCodes", function($event) { $qrcodes = $event->return; // keep everything except the QR codes generated from editUrl foreach($qrcodes as $key => &$qrcode) { if($qrcode["source"] === "editUrl") { unset($qrcodes[$key]); } } unset($qrcode); $event->return = $qrcodes; })

      AppApiFile adds the /file endpoint to the AppApi routes definition. Makes it possible to query files via the api. 
      This module relies on the base module AppApi, which must be installed before AppApiFile can do its work.
      Features
      You can access all files that are uploaded at any ProcessWire page. Call api/file/route/in/pagetree?file=test.jpg to access a page via its route in the page tree. Alternatively you can call api/file/4242?file=test.jpg (e.g.,) to access a page by its id. The module will make sure that the page is accessible by the active user.
      The GET-param "file" defines the basename of the file which you want to get.
      The following GET-params (optional) can be used to manipulate an image:
      width height maxwidth maxheight cropX cropY Use GET-Param format=base64 to receive the file in base64 format.

      This fieldtype and inputfield bundle was built for storing measurement values within a field, rendering them in a variety of formats and converting them to other units or otherwise modifying them via the API.
      The API consists of a number of predefined functions, some of which include...
      render() for rendering the measurement object, valueAs() for converting the value to another unit value, convertTo() for converting the whole measurement object to different units, and add() and subtract() for for modifying the stored value by the value (converted as required) in another measurement. In the admin the inputfield includes a checkbox (which can be optionally disabled) for converting values on page save. For an example if a value was typed in as centimeters, the unit was changed to metres, and the page saved with this checkbox selected, said value would be automatically converted so that e.g. 170 cm becomes 1.7 m.

      A simple length field using Fieldtype Measurement and Inputfield Measurement.
      Combination units (e.g. feet and inches) are also supported.
      Please note that this module is 'proof of concept' at the moment - there are limited units available and quite a lot of code tidying to do. More units will be added shortly.
      See the GitHub at https://github.com/MetaTunes/FieldtypeMeasurement for full details and updates.
