Easily insert any complex HTML, Javascript or PHP output in your ProcessWire content by creating your own Hanna code tags.
This module is based loosely on the WordPress Hana Code Insert plugin.

A Hanna code tag looks like [[hello_world]]. A Hanna code tag with attributes looks like [[hello_world foo=bar" bar="foo]] using HTML style attributes or [[hello_world foo=bar, bar=foo]] using ProcessWire selector style attributes. After installing the module, you define your Hanna codes in Setup > Hanna Code.
 
These Hanna codes that you define can then be entered within your body copy (or other text where you allow) and they will be replaced with the values defined or generated by your Hanna code. A common use case is to embed scripts or other bits of HTML or codes that would usually be stripped out by an editor like TinyMCE. However, Hanna codes can be more than just static snippets--they can be dynamic PHP or Javascript that outputs different things according to the request. PHP-based Hanna codes have access to the entire ProcessWire API.
 
Hanna code accepts named attributes in the tag that can be passed as variables to PHP and Javascript Hanna codes. These attributes can be specified either in HTML attribute format or ProcessWire selector format. In either case, quotes should be used around the attribute value when the value contains whitespace or a comma.
 
How to install
  • Place the module files in /site/modules/TextformatterHannaCode/
  • In your admin, click Modules > Check for new modules
  • Click install for TextformatterHannaCode
  • Now to go Setup > Fields and locate the Textarea field(s) that you want to use Hanna codes with ("body" for instance). 
  • When editing the field, click the details tab, and select "Hanna Code" as the Textformatter. Save.
  • Now go to Setup > Hanna Code and start defining your Hanna Codes! You may want to use one of the examples from this document to get started.
Tag format
 
Below is a Hanna code tag named hello_world with no attributes. If you pasted this into your body copy, you would get whatever the replacement value is that you defined.
[[hello_world]]
Below is a Hanna code tag named hello_world being passed attributes of foo, bar and foobar. If this were a PHP-based Hanna code, it would receive the variables $foo, $bar and $foobar:
[[hello_world foo="bar" bar="foo" foobar="foo bar"]]
Below is the same Hanna code tag as above, but with attributes more like ProcessWire selectors. You can use whatever format you prefer. Just note that unlike regular ProcessWire selectors, quotes (single or double) are required around any value that has whitespace.
[[hello_world, foo=bar, bar=foo, foobar="foo bar"]] 
How to use
 
Please make sure that you have completed the How to install section first. Then in your admin, go to Setup > Hanna Codes.
 
Each Hanna code that you add has a type of either: Text/HTML, Javascript or PHP. The Text/HTML type is literally self explanatory in that your [[custom-tag]] is replaced with exactly the text you paste in. Anywhere that you type your [[custom-tag]] in your body copy will be replaced with exactly the static text you defined.
 
More power opens up with the Javascript and/or PHP types of codes. These codes execute at runtime and thus can contain specific logic to produce different results. In fact, PHP Hanna codes have access to the entire ProcessWire API and are executed in the same manner as template files. Your PHP-based Hanna code should simply "echo" or "print" the replacement value.
 
PHP example
  • Create a new Hanna code with the name "children".
  • Select "PHP" as the type.
  • Paste in the following for the code:
foreach($page->children as $child) {
  echo "<p><a href='$child->url'>$child->title</a>";
}
  • Now go and edit a page that has children. In the body copy, enter [[children]] in the place where you want the output to appear.
  • View the page, and you should see the rendered list of links to children.
PHP example, part 2
 
Now lets take the above example further...
  • Go back and edit your "children" Hanna code, as we are going to modify it to respond to a "parent" attribute. Change the code to this:
if(isset($parent)) {
  // If $parent is an ID or path, lets convert it to a Page
  $parent = $pages->get($parent);
} else {
  // otherwise lets assume the current page is the parent
  $parent = $page; 
}

foreach($parent->children as $child) {
  echo "<p><a href='$child->url'>$child->title</a>";
}
  • Go back and edit the page where you previously inserted the [[children]] tag, and change it to: [[children, parent=1]] (specifying the homepage) or [[children, parent=/path/to/some/parent/]] if you want to try something else.
  • View the page and you should now see it showing the children of the homepage (or of another parent you specified).
Please see the Javascript and PHP usage notes on the Hanna code entry screen.
 
Security
 
There are major security implications with a tool that will let you enter unfiltered text and code from your web browser. As a result, Hanna codes are meant for definition only by superusers and we recommend keeping it that way.

Just a note to all MODx'ers - I think this is a nice way to transfer some snippets/chunks to ProcessWire as well if people want to go down that route and have some they used to use in body text. Obviously it's not quite the same thing (potentially more powerful depending on your needs), but anything that helps make a transition easier is good in my book :)

Very useful, powerful module ryan!

Wow! Great module, Ryan.

Gonna create a bunch of snippets for quick prototyping and trying things. Expect a new wave of MODx'ers on the forum. These folks love using code snippents the way Hanna Code allows it!

Edit: Pete, we had almost the same thought!

Wow! Nice one; you've been busy!

Yes, there have been two or three questions from MODx'ers in the forums about something like this - the ability to randomly, directly call snippets, chunks and TVs within the body field/area in TinyMCE. Previously they've been pointed to shortcodes and tag parser. Hanna is certainly more powerful and would solve this issue easily.

I can't wait to see the creative ways people use this :rolleyes: .

Thx for the module!

Looks like a very useful module, thanks for sharing it Ryan.

I just tried to install it using ModulesManager, and I can't install it right after downloading as it requires Textformatter module to be installed.

TemplateFile: Module ProcessHannaCode requires: TextformatterHannaCode

#0 [internal function]: Modules->___install('ProcessHannaCod...')...

Couldn't it be installed when installing the process module?

Edit: When I create a new hanna code and not enter a tag name and save I get an error and can't see the form.

This looks brilliant Ryan, thank you! There are parallels with a nice aspect of Textpattern here also, TXP 'Forms' (snippets). Brill! ^_^

Works fine if you use default Module manager (PW's). You can only install via TextformatterHannaCode actually. Summary says this "Also Installs - ProcessHannaCode". The install button for  ProcessHannaCode is greyed out with the message "Requires - TextformatterHannaCode". ProcessHannaCode auto installs. Maybe something with ModulesManager?

@Ryan: The TextformatterHannaCode and ProcessHannaCode have the same name - "Hanna Code" in PW module manager. This can be confusing :) (but not a big deal).

@kongodo, but I don't use Modules page anymore :D I didn't see that the Textformatter is the mother module. At the end it got installed but it's confusing.

Of course it has to do with ModulesManager and the nature of the modules. Modules Manager doesn't know what modules are there and how to install. It takes the module "class name" that is entered on modules.processwire.com to create folder and installs the main module. It's all information I got from modules.processwire.com and there's no manifest, dependencies or lifecycle informations to modules in PW (which IMO is requires rather sooner than later)

For some reason it seems now Ryan has changed the module class name to "TextformatterHannaCode", and this should work better now. Though changing those settings "class name" is dangerous once the module is installed via ModulesManager, because there's actually two different folders for the same module.

Sorry about that, I went back and forth on the name a couple times and ultimately entered the wrong class name in the modules directory. It should have been TextformatterHannaCode, not ProcessHannaCode. I have corrected that.

Edit: When I create a new hanna code and not enter a tag name and save I get an error and can't see the form.

I was throwing an exception when I shouldn't have. I'm pushing a correction for this. 

 The TextformatterHannaCode and ProcessHannaCode have the same name - "Hanna Code" in PW module manager. This can be confusing :) (but not a big deal).

Technically they are part of the same program "Hanna Code", even if that program has two modules. But I know what you mean. I'm adding "(Process)" to the Process one, just so that the two next to each other can be differentiated. 

Also, one more section I just added to the README:

Using Hanna Code from the API
 
If you want to populate Hanna Code from the API, you can do so using the render() method, like this:
$hanna = $modules->get('TextformatterHannaCode'); 
$page->body = $hanna->render($page->body);

Just posted version 0.0.2 that addresses the items above. It also adds an option that lets you specify whether the immediate surrounding HTML tag should be replaced with your Hanna Code output or not. For instance, if your [[hello-world]] Hanna Code output is "Hello World" and is applied to the body copy containing "<p>[[hello-world]]</p>" then you probably don't want it to replace the surrounding <p> tags. Whereas if your Hanna Code outputs block level elements like "<ul><li>Hello World</li></ul>" then you probably do want it to replace the surrounding <p> tags, otherwise you'd end up with some invalid markup like: <p><ul><li>Hello World</li></ul></p>.

I have tested Hanna with single {, ( and [, i.e. 

(hello)
[hello]
{hello} 
They all work fine in both PHP and Text mode.

Ryan, are these OK or they could throw up issues? Thx.

I think it would be really cool if there was and easy (JSON?) way to import/export hanna codes (all or single). Maybe then we could setup a subforum to share them.

Otherwise this is amazing, thanks Ryan.

Is it just me or is Hanna version 1.0.4 broken? It no longer works - it outputs the raw tag :(

Don't know what's happening but even older versions do not work any more. I'm stumped. Ideas? Using it on 2.3 stable

It's working for me at least, though I did change some things about the regex's in 0.0.4, so I might need to get more info about the context. What's an example of a tag that isn't working for you? What is the markup that surrounds it in your text? Also can you double check that "Hanna Code" is set as the textformatter for your body field (or whatever field you are using it in) in Setup > Fields > body > details?

Ryan, are these OK or they could throw up issues? Thx.

It should be fine to set your open/close tags to be whatever you want. Though [this] is a fairly common text construct, where as [[this]] is not. So if your [this] ever conflicts with the name of a Hanna Code, that could cause some confusion. As a result, I think it may be preferable to use open/close tags that don't duplicate things you would usually see in written copy.

Sorry; I just wasted your precious time! I forgot to set it as my textformatter after I made a couple of changes!  :-[ Thanks :)

What kills me about this module is that Ryan literally decided to make it because I had something similar in WordPress and needed a substitute solution in ProcessWire (as part of the move of CMS Critic to PW) otherwise I'd have a ton of weird shortcodes in my posts for no reason. He made this module, imported my code from the other module (called Hana Code in WP) and named his Hanna Code (after his daughter) and Poof! a module is born.

I am insanely jealous of his mad php skills (but glad they can be bought!)

Ryan, brilliant stuff!
 

For me it won't work in my first attempt and it took me some time to figure out my failure.

You can't use the identifier "name" for a variable.

[[gallery name="Test"]]

I didn't found any comments on this issue, so perhaps it helps.

Kent, that's correct–I'll update the readme file. The term "name" is set to the name of the Hanna code. This is provided to the PHP so that it can check the name of the code, just in case it needs it. Likewise, it's preferable not to use any API variable name for your attributes either.

      Hello community!

      I want to share a new module I've been working on that I think could be a big boost for multi-language ProcessWire sites.

      Some background, I was looking for a way for our company website to be efficiently translated as working with human translators was pretty laborious and a lack of updating content created a divergence between languages. I, and several other devs here, have talked about translation integrations and have recognized the power that DeepL has. DeepL is an AI deep learning powered service that delivers translation quality beyond any automated service available. After access to the API was opened up to the US, I built Fluency, a DeepL translation integration for ProcessWire.
      Fluency brings automated translation to every multi-language field in the admin, and also provides a translation tool allowing the user to translate their text to any language without it being inside a template's field. With Fluency you can:
      Translate any plain textarea or text input Translate any CKEditor content (yes, with markup) Translate page names for fully localized URLs on every page Translate your in-template translation function wrapped strings Translate modules Fluency is free, and now so is DeepL
      Since this module was first built DeepL has introduced free Developer accounts that allow anyone to start using Fluency at zero cost and beginning with the version 0.3.0 release Fluency now supports free DeepL accounts. As of June 2021 DeepL supports translation to 26 languages and continues to offer more!
      Installation and usage is completely plug and play. Whether you're building a new multi-language site, need to update a site to multi-language, or simply want to stop manually translating a site and make any language a one-click deal, it could not be easier to do it. Fluency works by having you match the languages configured in ProcessWIre to DeepL's. You can have your site translating to any or all of the languages DeepL translates to in minutes (quite literally).
      Let's break out the screenshots...
      When the default language tab is shown, a message is displayed to let users know that translation is available. Clicking on each tab shows a link that says "Translate from English". Clicking it shows an animated overlay with the word "Translating..." cycling through each language and a light gradient shift. Have a CKEditor field? All good. Fluency will translated it and use DeepL's ability to translate text within HTML tags. CKEditor fields can be translated as easily and accurately as text/textarea fields.

      Repeaters and AJAX created fields also have translation enabled thanks to a JavaScript MutationObserver that searches for multi-language fields and adds translation as they're inserted into the DOM. If there's a multi-language field on the page, it will have translation added.

      Same goes for image description fields. Multi-language SEO friendly images are good to go.

      Creating a new page from one of your templates? Translate your title, and also translate your page name for native language URLs. (Not available for Russian, Chinese, or Japanese languages due to URL limitations). These can be changed in the "Settings" tab for any page as well so whether you're translating new pages or existing pages, you control the URLs everywhere.

      Language configuration pages are no different. Translate the names of your languages and search for both Site Translation Files (including all of your modules)

      Translate all of the static text in your templates as well. Notice that the placeholders are retained. DeepL is pretty good at recognizing and keeping non-translatable strings like that. If it is changed, it's easy to fix manually.

      Fluency adds a "Translate" item to the CMS header. When clicked this opens up a modal with a full translation tool that lets the user translate any language to any language. No need to leave the admin if you need to translate content from a secondary language back to the default ProcessWire language. There is also a button to get the current API usage statistics. DeepL account owners can set billing limitations via character count to control costs. This may help larger sites or sites being retrofitted keep an eye on their usage. Fluency can be used by users having roles given the fluency-translate permission.

      It couldn't be easier to add Fluency to your new or existing website. Simply add your API key and you're shown what languages are currently available for translation from/to as provided by DeepL. This list and all configuration options are taken live from the API so when DeepL releases new languages you can add them to your site without any work. No module updates, just an easy configuration. Just match the language you configured in ProcessWire to the DeepL language you want it to be associated with and you're done. Fluency also allows you to create a list of words/phrases that will not be translated which can prevent items such as brands and company names from being translated when they shouldn't

       
      Limitations:
      No "translate page" - Translating multiple fields can be done by clicking multiple translation links on multiple fields at once but engineering a "one click page translate" is not feasible from a user experience standpoint. The time it takes to translate one field can be a second or two, but cumulatively that may take much longer (CKEditor fields are slower than plain text fields). There may be a workaround in the future but it isn't currently on the roadmap. No "translate site" - Same thing goes for translating an entire website at once. It would be great, but it would be a very intense process and take a very (very) long time. There may be a workaround in the future but it isn't on the roadmap. No current support for Inline CKEditor fields - Handling for CKEditor on-demand hasn't been implemented yet, this is planned for a future release though and can be done. I just forgot about it because I've never really used that feature personally.. Alpha release - This module is in alpha. Releases should be stable and usable, but there may be edge case issues. Test the module thoroughly and please report any bugs via a Github issue on the repository or respond here. Please note that the browser plugin for Grammarly conflicts with Fluency (as it does with many web applications). To address this issue it is recommended that you disable Grammarly when using Fluency, or open the admin to edit pages in a private window where Grammarly may not be loaded. This is an issue that may not have a resolution as creating a workaround may not be possible. If you have insight as to how this may be solved please visit the Github page and file a bugfix ticket.
      Requirements:
      ProcessWire  3.0+ UIKit Admin Theme That's Fluency in a nutshell. A core effort in this module is to create it so that there is nothing DeepL related hard-coded in that would require updating it when DeepL offers new languages. I would like this to be a future-friendly module that doesn't require developer work to keep it up-to-date.
      The Module Is Free
      This is my first real module and I want to give it back to the community as thanks. This is the best CMS I've worked with (thank you Ryan & contributors) and a great community (thank you dear reader).
      DeepL Developer Accounts
      In addition to paid Pro Developer accounts, DeepL now offers no-cost free accounts. Now all ProcessWire developers and users can use Fluency at no cost.
      Learn more about free and paid accounts by visiting the DeepL website. Sign up for a Developer account, get an API key, and start using Fluency today.

      (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 !)
      Github: https://github.com/romaincazier/FieldtypeQRCode
      Modules directory: https://processwire.com/modules/fieldtype-qrcode/
      This is a simple module I made so a client could quickly grab a QR Code of the page's url in the admin.
      There's not much to it for now, but if need be you can output anything using a hook:
      $wire->addHookAfter("FieldtypeQRCode::getQRText", function($event) { $event->return = "Your custom text"; }) You can also output the QR code on your front-end by calling the field:
      echo $page->qr_code_field; The module uses the PHP library QR Code Generator by Kazuhiko Arase. When looking for a way to generate a QR Code in PW I came across @ryan's integration in his TFA module. I'm not very familiar with fieldtype/inputfield module development so I blindly followed @bernhard (great) tutorial and his BaseFieldtypeRuntime. At some point I'll take a deeper look to make a module on my own.
      Some ideas for improvements :
      add the ability to choose what to ouput : page's url / editUrl / file(s) / image(s) / ... allow to output multiple QR codes ?

      Inspired by @bernhard's excellent work on the new customisable LESS CSS getting rolled into the core soon, I thought I would offer up the module for beta testing, if it is of interest to anyone.

      It takes a different approach to admin styling, basically using the Cascade part of CSS to over-ride default UiKit values.
      Values are stored in ModuleConfig Module creates a separate AdminThemeTweaker Folder at root, so it can link to AdminThemeTweaker.php as CSS AdminThemeTweaker.php reads the module values, constructs the CSS variables then includes the CSS framework Can be switched on and off with a click. Uninstall removes everything, thanks to bernhard's wonderful remove dir & contents function.
      It won't touch your core. It won't care if stuff is upgraded. You won't need to compile anything and you don't need to touch CSS unless you want to.

      It won't do much at all apart from read some values from your module config, work out the right CSS variables to use (auto contrast based on selected backgrounds) and throw it on your screen.
      You can configure a lot of stuff, leave it as it comes (dark and curvy), change two main colors (background and content background) or delve deep to configure custom margins, height of mastheads, and all manner of silly stuff I never use.

      Have been developing it for somewhere around 2 years now. It has been (and will continue to be) constantly tweaked over that time, as I click on something and find something else to do.
      That said, it is pretty solid and has been in constant use as my sole Admin styling option for all of those 2 years.

      If nothing else, it would be great if it can provide any assistance to @bernhard or other contributor's who may be looking to solve some of the quirkier UiKit behavior.
      Has (in my opinion) more robust and predictable handling of hidden Inputfields, data-colwidths and showIf wrappers.
      I am very keen to help out with that stuff in any way I can, though LESS (and any css frameworks/tools basically) are not my go.
      I love CSS variables and banging-rocks-together, no-dependency CSS you can write with notepad.

      I see old posts saying that repeaters are not the way to go in Custom Process Modules. If that is the case, when using forms (as I am trying to do) how would one tackle things like repeat contact fields where there can be multiple requirements for contact details with different parameters? (Like point of contact, director, etc) or even telephone numbers that have different uses?
      Just for background I am creating a process module that allows me to create types of financial applications in the admin area (no need to publish any of this, pure admin) that require a lot of personal or company information.
      Maybe I am thinking about this incorrectly?
