Hanna Code

Recommended Posts

It's render($field), not render([

]). So jmartsch example is little off.

Actually doesn't work. But with the fix both work.

Thanks guys, and sorry about the bug there. The problem was actually not what was highlighted above, but this line: 

public function render($value) {
  $value = $this->formatValue(new NullPage(), new Field(), $value); // this line
  return $value; 
}
...is supposed to be this:
public function render($value) {
  $this->formatValue(new NullPage(), new Field(), $value); // this line
  return $value; 
}

The formatValue function accepts $value as reference, not a separate copy (i.e. &$value rather than $value). So the line that blanks out $this->value is intentional. The point of that is to clear the memory, ensuring the module doesn't keep a separate copy of the text, since it no longer is working with it. So if you commented that line, I would uncomment it again. Actually I'm updating the source to fix the issue now, so you can also just grab the latest version.

Hey Ryan. Thanks for the quick fix :)

Now the PHP example works, but why can´t we use Hanna Code directly in our template files just by using [[name_of_hanna_code_snippet]]?

Are there performance issues?

Another problem.

If i set Hanna Code Text Formatter for the field body and then want to output the body field in my template via PHP, all other code from my Hanna Code snippet is overwritten. Only the field $page->body appears.

To clarify, here is what i got:

Field with the name body -> Text Formatter: Hanna Code Text Formatter

Hanna code:

!HannaCode:newsdetails: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/!HannaCode

here is the PHP for the Hanna Code:

echo $page->title;

if($page->thumbnail){
	$image ="<a href='{$page->thumbnail->url}' class='lightbox'>";
	$image .="<img class='pull-right img-polaroid' src='{$page->thumbnail->width(200)->url}'>";
					// $image .="<img class='pull-right img-polaroid' src='{$page->thumbnail->getThumb(thumbnail)}'>";
	$image .="</a>";
}

echo $image;
echo $page->body;

template newsdetail.php

<?php
$hanna = $modules->get('TextformatterHannaCode'); 
echo $hanna->render('[[newsdetails]]');
?>

When i open the page, only the contents of the body field appear.

No Hanna Code is actually used in the body field. Just plain text!!!!

If i remove the text formatter for the body field, everything works fine.

But sometimes i want to use Hanna Code in my body field as well.

So how do i do that?

Actually you could do this by hooking $hanna->render() into Page::render. But I don't recommend it because then you always have to filter for Hanna Codes in any user input that gets echoed back to the screen. Basically, it just opens up security issues that would be potentially difficult for someone to keep track of. It's a lot safer to be specific and just render Hanna Codes in the blocks of content you intend. 

When i open the page, only the contents of the body field appear.

No Hanna Code is actually used in the body field. Just plain text!!!!

The problem I can see with your Hanna Code is that it's echoing $page->body. Your Hanna Code should only echo what actually replaces the tag. Maybe that's what you want when you do a call like $hanna->render("[[newdetails]]"); but that's definitely not what you want to be textformatting your $page->body field -- seems like that could potentially result in an infinite loop.

I've posted an update to Hanna Code to address some of the things brought up earlier:

  • It now comes with a proper code editor (Ace Editor). You can configure the theme and editor height in the ProcessHannaCode module settings. 
  • There is now a "Save & Test" option. When you click that, it will save then attempt to run the Hanna code. This is primarily useful for determining if you have any PHP parse errors or the like. 
  • The default behavior of "Save" is now to continue editing, rather than going back to the list of Hanna codes. There is now a separate "Save & Exit" button to do that. 
  • The interface now uses tabs.

Just tested on 2.3.2.

Save does not continue editing; instead, it saves then goes to the add new Hanna Code screen  :)

Edit:

The above refers to when you create a new Hanna Code. I was expecting save to let me continue editing; however, it takes me to the add new screen. In the case of existing Hanna Codes, if I edit them, save works as stated; I can continue editing.

Thanks, will test.

Btw, does it matter that the folder name has changed from TextformatterHannaCode to ProcessHannaCode from the point of view of installing/updating via Modules Manager? I recently got a gotcha when updating a module (I think it was PageDelete) who's folder name had changed to ProcessPageDelete or similar). I got a cannot redeclare class fatal error. What happened is that the update did not replace the old folder, hence, the class was getting called twice. Maybe the module name had changed as well, come to think of it..

It's best that the directory name and filename don't change after it's installed. It should be uninstalled first, deleted, then re-installed, if such things change. I

It looks like I've got a disconnect between the class name listed on the modules directory and the repository name at GitHub. The class name listed in the modules directory is what should be used for the directory name (TextformatterHannaCode). Though you certainly could install it under ProcessHannaCode too, but this would confuse the modules manager (including the built-in one). So I recommend using a folder name of TextformatterHannaCode for compatibility with the modules directory.

Ryan, is there a reason why I have to use echo instead of my preferred approach to using php when templating? i.e.:

<?
if ($page->rootParent->numChildren > 0) {
?>
	<nav>
		<ul class="subnav">
		<? 
		foreach($page->rootParent->children as $child) { 
		?>
			<li <? if($page === $child) echo 'class="active"' ?> ><a href='<?= $child->url ?>'><?= $child->title ?></a></li>
		<? 
		} 
		?>
		</ul><!-- /subnav -->
	</nav>
<?
}
?>

I really prefer the markup-first approach to keep the markup as structured and readable as possible (well, at least to my eyes). I'd hate to have to convert all of my code snippets in order to use them with hanna code.

When you specify PHP as the type, then the Hanna code is a block of PHP. But you should be able to specify a closing PHP tag like ?> and then be in your HTML. If that does not work, start your Hanna code with: <?php ?>, which should prevent Hanna code from automatically inserting an opening PHP tag, and leave you in HTML.

Hey Ryan,

How would you recommend using Hanna code to wrap a larger amount of markup? For example, if a client wants to create a two column layout within a body section. E.g. In TinyMCE:

[[col2 content=

This is a block of content...

]]

This seems to work with the following simple PHP as a hanna code tag:

<?php echo "<div class=\"column\">\n".trim($content)."\n</div>\n"; ?>

When its output, I get invalid formatting much like this: (with closing and opening tags still being output due to breaks in hanna code tag within TinyMCE.

<div class="column"></p><p>This is content</p><p></div>

Would there be a way to create a hanna code tag wrapper type?

E.g.

[[col2]]

This is a block of content...

[[/col2]]

@ryanscherler

i've been doing that sort of thing by just using 2 hanna codes, one for the opening markup and one for the closing markup;

like this:

[[col2]]

This is a block of content...

[[_col2]]

eventually if the shortcodes module supports more than 1 shortcode per page, then this would be pretty easy to do with shortcode;

the biggest thing i'm lacking now in terms of hanna/shortcode is with respect to tabs and accordions, and being able to sometimes put a set of tabs inside a body content;

like this:

[[tab title=Tab 1]]

Tab content 1

[[tab title=Tab 2]]

tab content 2

[[/tabs]]

sometimes though you need to be able to just put in a section of a body with 2 columns, so repeaters are less flexible; and also a lot of sites i do have flexible column layouts like 1/3 - 2/3 or 1/5 - 4/5

shortcodes work ok for columns, but can be tricky with hanna codes if you need a column wrapper

[[columns]]

[[column50]]

text

[[_column]]

[[column50]]

text

[[_column]]

[[_columns]]

Other possibility:

[[page rendered]] <--- actual $page (wrapper)

    // child page, 2 rows in repeater
    [col-50]txt[/col-50] - [col50]txt[/col50]

    // child page, 3 rows in repeater
    [col-33]txt[/col-33] - [col-33]txt[/col-33] - [col33]txt[/col33]

    // child page, 1 row in repeater
    [col-100]txt[/col-100]

    // child page, 4 rows in repeater
    [col-25]txt[/col-25] - [col-25]txt[/col-25] - [col-25]txt[/col-25] - [col-25]txt[/col-25]

[[/page rendered]]

i get it.. that's a cool idea; but maybe a simple hanna code in combo with this:

http://welcome.totheinter.net/columnizer-jquery-plugin/

could be really the way to go for columns...

you could setup the js for some different columns and then use hanna for placing the div with the correct class before and after the text... then you could do this:

[[2col]]

a lot of text which will be rendered in multiple columns

[[_2col]]

it's responsive

Or:

Every repeater is a row <div class='row'>

Repeater with a body field. (containing textformatter that splits the content in columns when finding a <hr />)

Currently you can't pass multiline arguments to Hanna code. But I'm not sure how user friendly that looks even if you could. What I would probably suggest is to populate your content in a dedicated field on the page and have your Hanna code automatically look in that field. For example, your [col2] Hanna code might look like this:

<?php
if(!empty($attr['content'])) $content = $attr['content']; // use content attribute if supplied
  else $content = $page->col2; // otherwise pull from "col2" field on page
// ...now $content is ready for you to use

I'm having trouble with this hanna code:

<?php
foreach($page->children as $child) {
    echo '<h2>' . $child->title . '</h2>';
    echo $child->body;
}
?>

it's not working (it does work in the template) but in the hanna code, it only outputs the body of the last child.

I can confirm this. My best bet is that you've got enabled HannaCode as a textformatter in the setting of the "body"-field. I'm not sure what's happening, but I guess Hanna Code calls itself again, and overwrites the output itself. As a workaround, you could use different body-fields in parent and children - one with, the other one without Hanna Code enabled.

      DEPRECATED
      I'm using this module in several projects, but it will likely not see any updates in the future. I'm not happy with it and I'm looking for ways to develop better solutions. RockTabulator was my first try, but I'm also not 100% happy with that. The tabulator library is great, but my module implementation is not. I hope to get a good solution soon, but it will be a lot of work...
      ---
      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.

      Support: Please note that this module might not be as easy and plug&play as many other modules. It needs a good understanding of agGrid (and JavaScript in general) and it likely needs some looks into the code to get all the options. Please understand that I can not provide free support for every request here in the forum. I try to answer all questions that might also help others or that might improve the module but for individual requests I offer paid support (please contact me via PM).
       
      Use Cases / Examples:
      Colored grid cells, Icons, Links etc. The Grid also has a "batcher" feature built in that helps communicating with the server via AJAX and managing resource intensive tasks in batches:

      Filters, PW panel links and instant reload on panel close:

      You can combine the grid with a chart library like I did with the (outdated) RockDataTables module:

      Hi there. I wrote a custom module for one of my projects. In fact I maybe want to use my module in other projects too. In order to be variable and customizable  I need to implement some custom hooks into my module. So I can afterwards hook into the my functions in order to modify them to match the needs of the new project.
      I tried simply defining functions with the '__' prefix. But that did not work. I'm imagining something like the following:
      <?php class MyClass { public function ___someFunction() { // Do something } } // ready.php $this->addHookBefore('MyClass::someFunction', function($event) { // some customization }); Is there a way to accomplish that?

      Hi everyone,
      Here's a new module that I have been meaning to build for a long time.
      http://modules.processwire.com/modules/process-admin-actions/
      https://github.com/adrianbj/ProcessAdminActions
       
      What does it do?
      Do you have a bunch of admin snippets laying around, or do you recreate from them from scratch every time you need them, or do you try to find where you saw them in the forums, or on the ProcessWire Recipes site?
      Admin Actions lets you quickly create actions in the admin that you can use over and over and even make available to your site editors (permissions for each action are assigned to roles separately so you have full control over who has access to which actions).
       
      Included Actions
      It comes bundled with several actions and I will be adding more over time (and hopefully I'll get some PRs from you guys too). You can browse and sort and if you have @tpr's Admin on Steroid's datatables filter feature, you can even filter based on the content of all columns. 

      The headliner action included with the module is: PageTable To RepeaterMatrix which fully converts an existing (and populated) PageTable field to either a Repeater or RepeaterMatrix field. This is a huge timesaver if you have an existing site that makes heavy use of PageTable fields and you would like to give the clients the improved interface of RepeaterMatrix.
      Copy Content To Other Field
      This action copies the content from one field to another field on all pages that use the selected template.
      Copy Field Content To Other Page
      Copies the content from a field on one page to the same field on another page.
      Copy Repeater Items To Other Page
      Add the items from a Repeater field on one page to the same field on another page.
      Copy Table Field Rows To Other Page
      Add the rows from a Table field on one page to the same field on another page.
      Create Users Batcher
      Allows you to batch create users. This module requires the Email New User module and it should be configured to generate a password automatically.
      Delete Unused Fields
      Deletes fields that are not used by any templates.
      Delete Unused Templates
      Deletes templates that are not used by any pages.
      Email Batcher
      Lets you email multiple addresses at once.
      Field Set Or Search And Replace
      Set field values, or search and replace text in field values from a filtered selection of pages and fields.
      FTP Files to Page
      Add files/images from a folder to a selected page.
      Page Active Languages Batcher
      Lets you enable or disable active status of multiple languages on multiple pages at once.
      Page Manipulator
      Uses an InputfieldSelector to query pages and then allows batch actions on the matched pages.
      Page Table To Repeater Matrix
      Fully converts an existing (and populated) PageTable field to either a Repeater or RepeaterMatrix field.
      Template Fields Batcher
      Lets you add or remove multiple fields from multiple templates at once.
      Template Roles Batcher
      Lets you add or remove access permissions, for multiple roles and multiple templates at once.
      User Roles Permissions Batcher
      Lets you add or remove permissions for multiple roles, or roles for multiple users at once.
       
      Creating a New Action
      If you create a new action that you think others would find useful, please add it to the actions subfolder of this module and submit a PR. If you think it is only useful for you, place it in /site/templates/AdminActions/ so that it doesn't get lost on module updates.
      A new action file can be as simple as this:
      class UnpublishAboutPage extends ProcessAdminActions { protected function executeAction() { $p = $this->pages->get('/about/'); $p->addStatus(Page::statusUnpublished); $p->save(); return true; } } Each action:
      class must extend "ProcessAdminActions" and the filename must match the class name and end in ".action.php" like: UnpublishAboutPage.action.php the action method must be: executeAction() As you can see there are only a few lines needed to wrap the actual API call, so it's really worth the small extra effort to make an action.
      Obviously that example action is not very useful. Here is another more useful one that is included with the module. It includes $description, $notes, and $author variables which are used in the module table selector interface. It also makes use of the defineOptions() method which builds the input fields used to gather the required options before running the action.
      class DeleteUnusedFields extends ProcessAdminActions { protected $description = 'Deletes fields that are not used by any templates.'; protected $notes = 'Shows a list of unused fields with checkboxes to select those to delete.'; protected $author = 'Adrian Jones'; protected $authorLinks = array( 'pwforum' => '985-adrian', 'pwdirectory' => 'adrian-jones', 'github' => 'adrianbj', ); protected function defineOptions() { $fieldOptions = array(); foreach($this->fields as $field) { if ($field->flags & Field::flagSystem || $field->flags & Field::flagPermanent) continue; if(count($field->getFieldgroups()) === 0) $fieldOptions[$field->id] = $field->label ? $field->label . ' (' . $field->name . ')' : $field->name; } return array( array( 'name' => 'fields', 'label' => 'Fields', 'description' => 'Select the fields you want to delete', 'notes' => 'Note that all fields listed are not used by any templates and should therefore be safe to delete', 'type' => 'checkboxes', 'options' => $fieldOptions, 'required' => true ) ); } protected function executeAction($options) { $count = 0; foreach($options['fields'] as $field) { $f = $this->fields->get($field); $this->fields->delete($f); $count++; } $this->successMessage = $count . ' field' . _n('', 's', $count) . ' ' . _n('was', 'were', $count) . ' successfully deleted'; return true; } }  
      This defineOptions() method builds input fields that look like this:

      Finally we use $options array in the executeAction() method to get the values entered into those options fields to run the API script to remove the checked fields.
      There is one additional method that I didn't outline called: checkRequirements() - you can see it in action in the PageTableToRepeaterMatrix action. You can use this to prevent the action from running if certain requirements are not met.
      At the end of the executeAction() method you can populate $this->successMessage, or $this->failureMessage which will be returned after the action has finished.
       
      Populating options via URL parameters
      You can also populate the option parameters via URL parameters. You should split multiple values with a “|” character.
      You can either just pre-populate options:
      http://mysite.dev/processwire/setup/admin-actions/options?action=TemplateFieldsBatcher&templates=29|56&fields=219&addOrRemove=add
      or you can execute immediately:
      http://mysite.dev/processwire/setup/admin-actions/execute?action=TemplateFieldsBatcher&templates=29|56&fields=219&addOrRemove=add

      Note the “options” vs “execute” as the last path before the parameters.
       
      Automatic Backup / Restore
      Before any action is executed, a full database backup is automatically made. You have a few options to run a restore if needed:
      Follow the Restore link that is presented after an action completes Use the "Restore" submenu: Setup > Admin Actions > Restore Move the restoredb.php file from the /site/assets/cache/AdminActions/ folder to the root of your site and load in the browser Manually restore using the AdminActionsBackup.sql file in the /site/assets/cache/AdminActions/ folder I think all these features make it very easy to create custom admin data manipulation methods that can be shared with others and executed using a simple interface without needing to build a full Process Module custom interface from scratch. I also hope it will reduce the barriers for new ProcessWire users to create custom admin functionality.
      Please let me know what you think, especially if you have ideas for improving the interface, or the way actions are defined.

      ---
      This module is (yet another) way for implementing a cookie management solution.
      Of course there are several other possibilities:
      - https://processwire.com/talk/topic/22920-klaro-cookie-consent-manager/
      - https://github.com/webmanufaktur/CookieManagementBanner
      - https://github.com/johannesdachsel/cookiemonster
      - https://www.oiljs.org/
      - ... and so on ...
      In this module you can configure which kind of cookie categories you want to manage:

      You can also enable the support for respecting the Do-Not-Track (DNT) header to don't annoy users, who already decided for all their browsing experience.
      Currently there are four possible cookie groups:
      - Necessary (always enabled)
      - Functional
      - Statistics
      - Marketing
      - External Media
      All groups can be renamed, so feel free to use other cookie group names. I just haven't found a way to implement a "repeater like" field as configurable module field ...
      When you want to load specific scripts ( like Google Analytics, Google Maps, ...) only after the user's content to this specific category of cookies, just use the following script syntax:
      <script type="text/plain" data-type="text/javascript" data-category="statistics" data-src="/path/to/your/statistic/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing" data-src="/path/to/your/mareketing/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="external_media" data-src="/path/to/your/external-media/script.js"></script> <script type="text/plain" data-type="text/javascript" data-category="marketing">console.log("Inline scripts are also working!");</script> The data-attributes (data-type and data-category) are required to get recognized by PrivacyWire. the data-attributes are giving hints, how the script shall be loaded, if the data-category is within the cookie consents of the user. These scripts are loaded asynchronously after the user made the decision.
      If you want to give the users the possibility to change their consent, you can use the following Textformatter:
      [[privacywire-choose-cookies]] It's planned to add also other Textformatters to opt-out of specific cookie groups or delete the whole consent cookie.
      You can also add a custom link to output the banner again with a link / button with following class:
      <a href="#" class="privacywire-show-options">Show Cookie Options</a> <button class="privacywire-show-options">Show Cookie Options</button>  
      I would love to hear your feedback 🙂

    • By joshua
      As we often use Matomo (former known as Piwik) instead of Google Analytics we wanted to embed Matomo not only in the template code but also via the ProcessWire backend.
      That's why I developed a tiny module for the implementation.
      The module provides the possibility to connect to an existing Matomo installation with the classical site tracking and also via the Matomo Tag Manager.
      If you have also PrivacyWire installed, you can tell MatomoWire to only load the script, if the user has accepted cookies via PrivacyWire.
      To offer an Opt-Out solution you can choose between the simple Opt-Out iFrame, delivered by your Matomo installation, or a button to choose cookies via PrivacyWire.
      You'll find the module both in the module directory and via github:
      ProcessWire Module Directory MatomoWire @ GitHub MatomoWire @ Packagist ->installable via composer require blauequelle/matomowire I'm looking forward to hear your feedback!
