Module: Template Latte Replace


Recommended Posts

Has anyone succeeded running Hanna Code with Latte template. I'm strugling getting them to work together. Is there  a setting to prevent latte to process Hanna Code tags ?


I haven't tried, but maybe changing the Open and Close tag settings in the Hanna code config might help you get around it:

Admin > Modules > Hanna Code Text Formatter

@adrian Already tried that but whatever the open and close tag choosen, Latte template will try to load the file with the name of the code. For example i have a Hanna code named "quote". Then i've got the following this error : Error: Exception: Missing template file '/Volumes/DATA/www/ceea/site/templates/views/quote.latte'

In the latte file i've got the following code

<div class="entry-main">
  <h3 class="entry-title ui-title-inner">{$page->title|noescape}</h3>
  <div class="entry-content">

The body field is configured to process Hanna Code as a text formatter

It is interesting because this is the way I use it and no issues here. What is your Latte module version and the open-close tags for Hanna?  Do you have other textformatters applied to body? I have Video Embed for Youtube/Vimeo and they work fine together.

I really like this module and the ease of the Latte syntax, but when trying to start my first project (both in Latte & PW) I found the following questions:

  1. Where implement the business logic for the @layout file? if this file is only for output and its not a good practice to include php logic. For example I need to do some processing before printing the site header and the area for the logged user.
  2. Following the previous question, if the option for including Blocks require a more complex data process, where I do that? I have no controller file for Blocks/Chunks and only can pass variables directly inside the Latte view that include it
  3. The multi-language native processwire system does not work, for example the url "sitename.com/es/" causes an include error.

I want to implement my sites using Latte, but now I'm worried if it suits the complexities that can appear during dev

perhaps Latte is not the best choice for beginners in PW but I guess you have some programming background judging from your questions :)

1. You can use ready.php for example for such purposes (or init.php, _init.php, perhaps _main.php). Or you can add two blocks to the layout, one for the site header and one for the logged in user. You can leave the block you don't need empty and it won't be rendered. I sometimes use PHP logic in my view files but it's rather because my lazyness :)

2. Well you do your logic in {template}.php and set variables to output in {template}.latte. You can use another .latte file in {template}.php, so eg. you can include login.latte or register.latte if you need that. You can even render a chunk in the php (controller) file to a variable and use in the final view file.

3. Could you provide more details? I've done all my PW multilanguage sites with Latte and haven't encountered such an error.

I think Latte is just as good as Twig or others, maybe a bit more forgivable in some cases. So I think the question for you is perhaps to use a template engine or not.

Here are two macros that I started to use recently to avoid passing full page objects and make things easier.

I usually set "common" pages in ready.php like this:

// Pages
$view->homepage = $pages->get(1);
$view->contactPage = $pages->get(1033);
// PageArrays
$view->menuItems = $pages->find('id=1010|1020|1030,sort=sort');

But instead of this I set only ID (selector):

// Pages
$view->homepage = 1
$view->contactPage = 1033;
// PageArrays
$view->menuItems = 'id=1010|1020|1030,sort=sort';

Now in latte template files I use the macro "n:page" or "n:pages", which automatically sets the "$p" variable ("$pArr" in case of n:pages).

Basically it sets the context:

<a n:page="$contactPage" class="contact" href="{$p->url}">{$p->title}</a>
<ul n:pages="$menuItems" n:inner-foreach="$pArr as $p">
    <li class="{$p|activeClass|noescape}">
        <a href="{$p->url}">{$p->title|noescape}</a>

You can use this if you prefer "normal" macros instead "n:macros":

{page $contactPage}

And here are the macros (put it in site/ready.php):

$view->_addMacro['page'] = array(
    '$p = \ProcessWire\wire("pages")->get(%node.word)',

$view->_addMacro['pages'] = array(
    '$pArr = \ProcessWire\wire("pages")->find(%node.word)',

Another tip today: a filter to easily get pages in templates :)


// homepage url (1: page ID)
<a href="{(1|getPage)->url}" class="logo">

// custom selector
<a href="{('name=about'|getPage)->url}" class="logo">

Filter (add to ready.php):

$view->_filters['getPage'] = function ($selector) {
    return isset($selector) ? wire('pages')->get($selector) : false;

I wouldn't recommend to use it with selectors but it's there if needed. It's better to use with variables set in template php files.

v2.4 is up:

  • added additional filters and macros (optional, see README)
  • added 'languages', 'fields', 'templates', 'logs' to the default API variables (suggested by Pixrael)
  • remove cache directory on uninstall

About the API variables: It seems perfect because in any medium projects you need almost all those variables, then from factory you have all the infrastructure ready to work. If you need something from the PW API it's there, it's much better for newbies. If you are a fan of optimizations (you are supposed to be a smart programmer) you can go to the module source and remove it, or whatever you want to do with it.

I was about to make (some) fuels optional but haven't noticed performance issues having all enabled. Editing the module is not a smart option, I can add a hook instead to modify the fuels to be loaded, if there's a need.

The new v025 has a new feature "Use latte extension" that allows replacing PHP templates with Latte files, resulting in a cleaner structure. Note that /site/templates/admin.php needs to be renamed to admin.latte when using this. On existing installations it is recommended to clear the cache too.

v027 contains some code improvements. There are two new filters, "count" and "breadcrumb". The latter is a bit different from the rest because it generates markup but it has many options to fine-tune. Currently it doesn't generate any separators between the items, I think it's better to do with CSS but let me know if you think otherwise.

  • root: root page to start the breadcrumb from (selector or Page). Default: Home page
  • addHome: whether to prepend the Home page. Default: true
  • addCurrent: append the current page. Default: false
  • addCurrentLink: whether to add link when appending the current page. Default: false
  • class: CSS class to add to the "ul" tag. Default: "breadcrumb". Pass an empty string to remove class.
  • id: CSS id to add to the "ul" tag. Default: none (no id added)
  • addAttributes: add "data-page" attributes to 'LI' tags with the corresponding page id. Default: false
{$page|breadcrumb:array('addCurrent' => true, 'addHome' => false, 'addCurrentLink' => true)|noescape}

      Field that stores one or more references to ProcessWire pages with additional data in field context.
      Values are editable via page edit modal of the referenced page provided from the field if module AdminPageFieldEditLinks is installed and "Enable link to create new pages?" is checked in field settings.
      Requirements: AdminPageFieldEditLinks >= 3.1.4
      Use case example:
      The planning of the Tonmeistertagung in the CCD (Congress Center Düsseldorf) from November 3rd, 2021 to November 6th, 2021 is in the finalization phase.
      The conference consists of a conference part and an exhibition. The planning is done via a separate frontendless PW instance. There, all companies (pages) that are active at various events are kept in a pool. Changes (address, logo) can always be done there. For the exhibition of the current conference in November, the exhibitor-companies (pages) are selected via a page reference field. A stand number must now be assigned to each selected company (page). We had originally solved this using the Profield FieldtypeTable. However, this had the disadvantage that each entry again made all companies available for selection and did not recognize which were already selected in a previous table row. The new field type now allows the value (company's stand number) to be assigned to a Company (page) in context to a specific Pagefield living in a specific page.

      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; } } });
