MarkupMenu

Recommended Posts

MarkupMenu is a markup module for generating menu trees. When provided a root page as a starting point, it generates a navigation tree (by default as a HTML "<ul>" element wrapped by a "<nav>" element) from that point onwards. If you've also provided it with current (active) page, the menu will be rendered accordingly, with current item highlighted and items rendered up to that item and its children (unless you disable the "collapsed" option, in which case the full page tree will be rendered instead).

Usage

As a markup module, MarkupMenu is intended for front-end use, but you can of course use it in a module as well. Typically you'll only need the render() method, which takes an array of options as its only argument:

echo $modules->get('MarkupMenu')->render([
    'root_page' => $pages->get(1),
    'current_page' => $page,
]);

Note: if you omit root_page, site root page is used by default. If you omit current_page, the menu will be rendered, but current (active) page won't be highlighted etc.

A slightly more complex example, based on what I'm using on one of my own sites to render a (single-level) top menu:

echo $modules->get('MarkupMenu')->render([
    'current_page' => $page,
    'templates' => [
        'nav' => '<nav class="{classes} menu--{menu_class_modifier}" aria-label="{aria_label}">%s</nav>',
        'item_current' => '<a class="menu__item menu__item--current" href="{item.url}" tabindex="0" aria-label="Current page: {item.title}">{item.title}</a>',
    ],
    'placeholders' => [
        'menu_class_modifier' => 'top',
        'aria_label' => 'Main navigation',
    ],
    'include' => [
        'root_page' => true,
    ],
    'exclude' => [
        'level_greater_than' => 1,
    ],
]);

Note: some things you see above may not be entirely sensible, such as the use of {menu_class_modifier} and {aria_label} placeholders. On the actual site the "nav" template is defined in site config, so I can define just these parts on a case-by-case basis while actual nav markup is maintained in one place.

Please check out the README file for available render options. I'd very much prefer not to keep this list up to date in multiple places. Basically there are settings for defining "templates" for different parts of the menu (list, item, etc.), include array for defining rules for including in the menu and exclude array for the opposite effect, classes and placeholders arrays for overriding default classes and injecting custom placeholders, etc. 🙂

MarkupMenu vs. MarkupSimpleNavigation

TL;DR: this is another take on the same concept. There are many similarities, but also some differences – especially when it comes to the supported options and syntax. If you're currently using MarkupSimpleNavigation then there's probably no reason to switch over.

I'd be surprised if someone didn't draw lines between this module and Soma's awesome MarkupSimpleNavigation. Simply put I've been using MSN (...) for years, and it's been great – but there are some issues with it, particularly in the markup generation area, and it also does some things in a way that doesn't quite work for me – the xtemplates thing being one of these. In some ways less about features, and more about style, I guess 🙂

Anyhow, in MarkupMenu I've tried to correct those little hiccups, modernise the default markup, and allow for more flexibility with placeholder variables and additional / different options. MarkupMenu was built for ProcessWire 3.0.112+ and with PHP 7.1+ in mind, it's installable with Composer, and I have a few additional ideas (such as conditional placeholders) still on my todo list.

One more small(ish) difference is that MarkupMenu supports overriding default options via $config->MarkupMenu. I find myself redefining the default markup for every site, which until now meant that each site had a wrapper function for MarkupSimpleNavigation (to avoid code / config repetition), and this way I've been able to leave that out 🙂

Requirements

  • ProcessWire >= 3.0.112
  • PHP >= 7.1.0

If you're working on an earlier version of ProcessWire or PHP, use MarkupSimpleNavigation instead.

Would be great if you could add an option to set markup of some popular css frameworks easily on your todo list as well 🙂 eg

$config->MarkupMenu = 'UIkit3';
// $config->MarkupMenu = 'Bootstrap4';
// ...

I think that's a brilliant idea, so definitely going to my todo list – thanks for the suggestion! 🙂

Just a quick heads-up that I've made a couple of updates to MarkupMenu recently:

## [0.8.0] - 2019-12-25

### Added
- Support for passing in a prepopulated PageArray of menu items via the menu_items option.

### Fixed
- Fixed an issue where include option root_page wasn't being properly reset (since 0.7.0).

## [0.7.0] - 2019-12-18

### Added
- New hookable method getItems().

### Changed
- Method renderTreeItem() made hookable.

0.7.0 made it possible to hook to the point when menu items are fetched (for an example if you need to inject a new item or remove an item at some specific point), and 0.8.0 added support for passing in a pre-defined PageArray to use as the first level of menu items (the need for this came up on a project where a menu was manually defined using a Page Reference field.)

      Hello
      Till now I hacked something with the twig template but it works no more with new PW versions so I look forward to create a module. I am working on a site in multiple languages : French, English, Italian, German, Spanish, Portuguese, Hebrew, Russian. The new posts are entered in any language with a field for language. Till now, I got twig files to get the translations with constants defined for each part of the pages.
      So I'd like to create a module to include theses files added according to the url /fr/en/...
      Have you some observations to do before I begin about the direction to take ?
      Thank you

      Mystique Module for ProcessWire CMS/CMF
      Github repo : https://github.com/trk/Mystique
      Mystique module allow you to create dynamic fields and store dynamic fields data on database by using a config file.
      Requirements
      ProcessWire 3.0 or newer PHP 7.0 or newer FieldtypeMystique InputfieldMystique Installation
      Install the module from the modules directory:
      Via Composer:
      composer require trk/mystique Via git clone:
      cd your-processwire-project-folder/ cd site/modules/ git clone https://github.com/trk/Mystique.git Module in live reaction with your Mystique config file
      This mean if you remove a field from your config file, field will be removed from edit screen. As you see on youtube video.
      Using Mystique with your module or use different configs path, autoload need to be true for modules
      Default configs path is site/templates/configs/, and your config file name need to start with Mystique. and need to end with .php extension.
      Adding custom path not supporting anymore !
      // Add your custom path inside your module class`init` function, didn't tested outside public function init() { $path = __DIR__ . DIRECTORY_SEPARATOR . 'configs' . DIRECTORY_SEPARATOR; Mystique::add($path); } Mystique module will search site/modules/**/configs/Mystique.*.php and site/templates/Mystique.*.php paths for Mystique config files.
      All config files need to return a PHP ARRAY like examples.
      Usage almost same with ProcessWire Inputfield Api, only difference is set and showIf usage like on example.
      <?php namespace ProcessWire; /** * Resource : testing-mystique */ return [ 'title' => __('Testing Mystique'), 'fields' => [ 'text_field' => [ 'label' => __('You can use short named types'), 'description' => __('In file showIf working like example'), 'notes' => __('Also you can use $input->set() method'), 'type' => 'text', 'showIf' => [ 'another_text' => "=''" ], 'set' => [ 'showCount' => InputfieldText::showCountChars, 'maxlength' => 255 ], 'attr' => [ 'attr-foo' => 'bar', 'attr-bar' => 'foo' ] ], 'another_text' => [ 'label' => __('Another text field (default type is text)') ] ] ]; Example:
      site/templates/configs/Mystique.seo-fields.php <?php namespace ProcessWire; /** * Resource : seo-fields */ return [ 'title' => __('Seo fields'), 'fields' => [ 'window_title' => [ 'label' => __('Window title'), 'type' => Mystique::TEXT, // or InputfieldText 'useLanguages' => true, 'attr' => [ 'placeholder' => __('Enter a window title') ] ], 'navigation_title' => [ 'label' => __('Navigation title'), 'type' => Mystique::TEXT, // or InputfieldText 'useLanguages' => true, 'showIf' => [ 'window_title' => "!=''" ], 'attr' => [ 'placeholder' => __('Enter a navigation title') ] ], 'description' => [ 'label' => __('Description for search engines'), 'type' => Mystique::TEXTAREA, 'useLanguages' => true ], 'page_tpye' => [ 'label' => __('Type'), 'type' => Mystique::SELECT, 'options' => [ 'basic' => __('Basic page'), 'gallery' => __('Gallery'), 'blog' => __('Blog') ] ], 'show_on_nav' => [ 'label' => __('Display this page on navigation'), 'type' => Mystique::CHECKBOX ] ] ]; Searching data on Mystique field is limited. Because, Mystique saving data to database in json format. When you make search for Mystique field, operator not important. Operator will be changed with %= operator.
      Search example
      $navigationPages = pages()->find('my_mystique_field.show_on_nav=1'); $navigationPages = pages()->find('my_mystique_field.page_tpye=gallery');

      This is a module I made as an experiment a while ago and never got around to releasing publicly. At the time it was prompted by discussions around using Repeater fields for "page builder" purposes, where the depth feature could possibly be used for elements that would be nested inside other elements. I thought it would be useful to enforce some depth rules and translate the depth data into a multi-dimensional array structure.
      I'm not using this module anywhere myself but maybe it's useful to somebody.
      Repeater Depth Helper
      This module does two things relating to Repeater fields that have the "Item depth" option enabled:
      It enforces some depth rules for Repeater fields on save. Those rules are:
      The first item must have a depth of zero. Each item depth must not be more than one greater than previous item depth. It provides a RepeaterPageArray::getDepthStructure helper method that returns a nested depth structure for a Repeater field value.
      Helper method
      The module adds a RepeaterPageArray::getDepthStructure method that returns a multi-dimensional array where the key is the page ID and the value is an array of nested "child" items, or null if there are no nested children.
      Example

      The module doesn't make any assumptions about how you might want to use the depth structure array, but here is a way you might use it to output a nested unordered list.
      // Output a nested unordered list from a depth structure array function outputNestedList($depth_structure, $repeater_items) { $out = "<ul>"; foreach($depth_structure as $page_id => $nested_children) { $out .= "<li>" . $repeater_items->get("id=$page_id")->title; // Go recursive if there are nested children if(is_array($nested_children)) $out .= outputNestedList($nested_children, $repeater_items); $out .= "</li>"; } $out .= "</ul>"; return $out; } $repeater_items = $page->my_repeater; $depth_structure = $repeater_items->getDepthStructure(); echo outputNestedList($depth_structure, $repeater_items);

      Cacheable Placeholders
      This module allows you to have pieces of dynamic content inside cached output. This aims to solve the common problem of having a mostly cacheable site, but with pieces of dynamic output here and there.  Consider this simple example, where you want to output a custom greeting to the current user:
      <h1>Good morning, <?= ucfirst($user->name) ?></h1> This snippet means you can't use the template cache (at least for logged-in users), because each user has a different name. Even if 99% of your output is static, you can only cache the pieces that you know won't include this personal greeting. A more common example would be CSRF tokens for HTML forms - those need to be unique by definition, so you can't cache the form wholesale.
      This module solves this problem by introducing cacheable placeholders - small placeholder tokens that get replaced during every request. The replacement is done inside a Page::render hook so it runs during every request, even if the response is served from the template cache. So you can use something like this:
      <h1>Good morning, {{{greeting}}}</h1> Replacement tokens are defined with a callback function that produces the appropriate output and added to the module through a simple hook:
      // site/ready.php wire()->addHookAfter('CachePlaceholders::getTokens', function (HookEvent $e) { $tokens = $e->return; $tokens['greeting'] = [ 'callback' => function (array $tokenData) { return ucfirst(wire('user')->name); } ]; $e->return = $tokens; }); Tokens can also include parameters that are parsed and passed to the callback function. There are more fully annotated examples and step-by-step instructions in the README on Github!
      Features
      A simple and fast token parser that calls the appropriate callback and runs automatically. Tokens may include multiple named or positional parameters, as well as multi-value parameters. A manual mode that allows you to replace tokens in custom pieces of cached content (useful if you're using the $cache API). Some built-in tokens for common use-cases: CSRF-Tokens, replacing values from superglobals and producing random hexadecimal strings. The token format is completely customizable, all delimiters can be changed to avoid collisions with existing tag parsers or template languages. Links

      This module allows you to integrate hCaptcha bot / spam protection into ProcessWire forms. hCaptcha is a great alternative to Google ReCaptcha, especially if you are in the EU and need to comply with privacy regulations.

      The development of this module is sponsored by schwarzdesign.
      The module is built as an Inputfield, allowing you to integrate it into any ProcessWire form you want. It's primarily intended for frontend forms and can be added to Form Builder forms for automatic spam protection. There's a step-by-step guide for adding the hCaptcha widget to Form Builder forms in the README, as well as instructions for API usage.
      Features
      Inputfield that displays an hCaptcha widget in ProcessWire forms. The inputfield verifies the hCaptcha response upon submission, and adds a field error if it is invalid. All hCaptcha configuration options for the widget (theme, display size etc) can be changed through the inputfield configuration, as well as programmatically. hCaptcha script options can be changed through a hook. Error messages can be translated through ProcessWire's site translations. hCaptcha secret keys and site-keys can be set for each individual inputfield or globally in your config.php. Error codes and failures are logged to help you find configuration errors. Please check the README for setup instructions.
