Hanna Code

Recommended Posts

Thanks mr-fan and Adrian. In case it's useful for someone, here is how I solved the problem. In fact I did not use Hanna Code in the end but some regex stuff, together with Adrians AdminActions Module (great work btw). I think this way you can convert any type of wordpress shortcuts to cleaner Hanna Code, get rid of not needed attributes or convert shortcuts to HTML.

Example: I wanted to convert this:

[av_image src='https://www.domain.de/link/to/image.jpg' attachment_size='large' align='center' lot_more='attributes'][/av_image]

to a regular img tag. So I used a regular expression like this one:

/\[av_image.*src='([^']*)([^\]]*)\]\[/av_image\]/

to match my shortcodes via the search and replace Action in AdminActions Module and replaced it with something like that:

<img src="$1">

Which leads to an ordinary image Tag. $1 stands for the first group which is the src attribute. With variations of this you can convert nearly everything. But if you're not familiar with regex (like me) it can be very tricky. Database restore feature of AdminActions Module saved me some times 😉  For testing and learning I used this tool which helped me a lot in creating the regex Expressions: https://www.phpliveregex.com/

Hello there.

I am working on a project and decided to try out Hanna Code tags to insert some custom HTML markup. The problem is that the markup includes some PHP variables to be checked and inserted at some spots. If I tell Hanna that the code is HTML, the php is just echoed and not processed. If I set the code as PHP, then my HTML is causing errors (of course).

So is it possible/wise to mix HTML and PHP inside of Hanna Code tags and if yes, how can I achieve that? 

Any examples of how to use HTML & PHP inside a single tag would be great.

If you set the HC to PHP, you would have to echo your HTML of course, or concatenate and then echo it.

<?php

$out .= '<div class="seo-block seo-interviews">';
$out .= "<h2>{$heading}</h2>";
$out .= '<ul>';
foreach( $interviews as $one ){
  $out .= "<li>
   // ...
  </li>";
}
$out .= '</ul>';
$out .= '</div>';
echo $out;

Hey @Klenkes I always get lazy which was the reason to search for a way to include only the PHP particles in my HTML. I came to the same conclusion as your suggestion, however, this morning. Thank you for it. I guess that for a big chunk of markup the mix of HTML and PHP would not make it read-friendly so I will bang it with PHP.

Thanks @LostKobrakai I will try both suggestions and see which one would be easier for me, fit better and most important, would be good to read. It might be a bit harder to turn the entire code to pure PHP due to the fact that there will be lots of html code to assign to $out and to align it, however I might not worry about it as I am planning to minify pages anyway. The more I touch HC, the more ways I see to use it where some user intervention is required but no manual file editing is a good idea.

P.S. I tested @LostKobrakai suggestion and can confirm that it works 100% with escaping the PHP tag at the beginning and then adding the HTML code. In my scenario there would be lots of interactions with the HC parameters which would be a part of a few selectors so it would make more sense to have them in PHP. At least if anyone is looking for HTML and PHP mix inside a Hanna Code tags, they could use either approach.

Just to mention for anyone coming across an issue using Hanna code blocks and having a <p>&nbsp;</p> which might mess up with the markup - it is not related to the module in any case but to the configuration of the field. I am not going to go to many details as there are quite a few topics that I've seen discussing it on other matters, so you could just find the best settings by changing the Text formatters, Content type and Beautify Markup Toggles (in my scenario, I removed empty paragraph tags and removed also non-breaking spaces.

Hey all. While playing with Hanna Code module I need to set some attributes to not be allowed to be empty (category name or some page listing counts). I know that in the markup I can check for those, however I would like to know is there any way to set the status of the attributes from the HC admin and eliminate the need of adding extra checks for that?

What I am trying to achieve is to have a custom tag inserting a block with page listings from different categories. Then I assign the list of the categories to an array to place them in the markup so I would like to restrict empty values from the attributes options shown in Hanna Dialogues.

P.S. In some cases some values defined in the attributes might be needed to be validated before they are submitted to the tag call for further verification (some numbers needing to be null, not null, bigger/smaller than..., required etc.) So far I was able to set the attributes I need, however the question is how can I achieve some initial validation before they values are passed to the module for processing (during submission or during save).

@MilenKo, just a quick note that I've merged your thread into the existing Hanna Code module support thread.

When you have questions regarding an existing module, please post them to the dedicated support thread (if one is available – you can find a link to the support thread from the Modules Directory entry for the module in question). Modules/Plugins area of the forum is intended for module-specific support threads, and there should be only one thread for each module. Thanks! 🙂

@teppo no problem. That is usually what I do but maybe I've over drank the coffee and got too much coding that day 😉 

P.S. I kind of completted my task by adding some checks in the code but it would be useful to know if I can add some checks before submitting the values of parameters to Hanna Code. Maybe I should check with @Robin S as he is the developer of HC Dialogues and it seems like the module addition could be easier to manupulate.

Can I use Hanna Code in any field? Even a page title, or the title of a repeater? 

I have a site where someone wants to replace a snippet of text with an image wherever it appears, body, title, other text fields etc. - thinking this might be suitable.

You should be able to.  Just assign the Hannacode Textformatter to the fields of your choice and it should work.

If you can add it on the Details tab as a Text Formatter, then it should work. Have you tried it? 😉

I have, now! It worked a treat. The only consideration was that my title field was also being used to populate the <title> tag so I had to be a bit smarter, retain the original text that was being replaced in Hanna Code's replacement and strip tags in the page title.

I hope someone can help me with the issue I'm facing when using Hanna Code.

I've installed Hanna Code using the instructions and I've made a couple of Hanna Code's. For example: one HTML Hanna Code with an image, so that I can easily show the same image on different pages within the content, so I also can change it easily.

But right now, the results of the codes just doesn't show. Hanna Code shows them when I view the Hanna Code's preview, but the shortcode ( the [[name here]] codes) don't turn into something else. I've an example here: https://smartranking.nl/blog/oude-berichten-weer-hoger-in-google-laten-verschijnen/.

The shortcut remains "[[cta-seo-consult]]".

Is anyone known with this problem? How can I fix it? I hope someone can give me the solution for it. I already tried different text formatting, but that also doesn't help.

Welcome to the forums @jarik

Make sure you've enabled Hanna Code as a text formatter for the textarea field where you want it to work. I am in a bit of a hurry. Have a look at the settings of your textarea field (details tab).

Hello gents.

I've been experimenting a lot lately with Hanna Code and Hanna dialogue which lead me to a full "News Block" code that can be inserted easily using CKEditor. My idea was to build a few similar news blocks and allow the admin to select the categories (represented by pages) for every block tabs etc.

Attached is a screen cast of what I have so far and it is working perfectly fine and as expected.

As usual, there is one HOWEVER 🙂 After some experimenting and adding few news pages (in my case as it is obvious some recipes), I was glad to see it all happening. The problem came, when I tried to insert the same Hanna Code block with the idea to show some different categories. What has happened is that the second block tabs came empty, but clicking on them started changing the navigation of the first one. From my humble experience with PHP I would guess that since Hanna code is using the same attributes, it affects the appearance of any other than the first block. So has any one ever came to a similar use and have found a solution that would allow to have multiple blocks inserted without an overlapping of the code of every one?

I am thinking about experimenting with inserting a random number after the block name which would be used for the tab number and tab content, however am not sure if there is a simpler or more elegant solution that I am missing yet...

Maybe it is important to mention that I am trying to accomplish a page builder using Hanna Code and Dialogue to allow selection of pages, add some limitations etc.

Nevermind, looking at the code, I found the answer - every time I called the hanna code, the tabs were having identical names, so this was causing the issue. To fix it I've added a simple random string to the tab names and it is all working fine now.

 

	$permitted_chars = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
	$rand = substr(str_shuffle($permitted_chars), 0, 10);

	$tab_name = "Tab" . $count . "-" . $rand;

This gives me an alphanumeric string of 10 chars length which aims to avoid a chance of duplicating again the tab names. I know it might be an overkil, but just don't want to take the risk of generating random number and have them matching 😉 As of now, the tab ID is something like: #Tab1-wrf7te0Y2x

Looking to use Hanna code with ProFields Table. Textformatter is not parsing the Hanna snippet. Can anyone give me the correct name of the formatter option since it needs to be manually added instead of selecting the TextFormatter option from the dropdown.

I use Hanna Code quite a lot, and especially with @Robin S's excellent dialog module. However, one thing I find a bit irritating is when you have lots of codes with php; the number of clicks to edit the php plus then needing to update the database (assuming you do this on a test version  before implementing live) is quite time consuming, often for quite trivial changes.

So: I am looking at re-engineering my codes along the following lines. Each code which needs php will just have the same code - something like

<?php
$result = hannaCode($input, $attr, $page, $hanna->name, $hanna->field, $hanna->value);
if (in_array('text', $result)) $hanna->value = $result['text'];
echo $result['out'];

Then, in a separate php file (probably "include"d  in init.php) I have a function 

hannaCode($input, $attr, $page, $hannaName, $hannaField, $hannaText)

with a switch on $hannaName to execute the code for that name.

This has 2 benefits:

  1. Any common code can go at the top, before the switch. E.g. I have 
    if ($page->template == 'admin') {
            $pId = $input->get('id');
            $page = wire('pages')->get($pId);
        }
        $helpArray = [
            'Property' => '[[Property]]: The name/title of the property (choose system name or title). Only works on a Booking page and its Mailing children',
    ..etc...
        ];
        if ($page->template == 'help-doc') {
            return ['out' => $helpArray[$hannaName]];
        }
    switch ...

     

  2. I can do simple edits in the IDE, test and upload without having to touch the database.

Has anyone else tried this. Any thoughts? Is it even worth a tut?

      Symprowire is a PHP MVC Framework based and built on Symfony using ProcessWire 3.x as DBAL and Service-Provider
      It acts as a Drop-In Replacement Module to handle the Request/Response outside the ProcessWire Admin. Even tough Symfony or any other mature MVC Framework could be intimidating at first, Symprowire tries to abstract Configuration and Symfony Internals away as much as possible to give you a quick start and lift the heavy work for you.
      The main Goal is to give an easy path to follow an MVC Approach during development with ProcessWire and open up the available eco-system.
      You can find the GitHub Repo and more Information here: https://github.com/Luis85/symprowire

      Twig Dependency Injection Monolog for Symprowire Support for .env YAML Configuration Symfony Console and Console Commands Symfony Webprofiler Full ProcessWire access inside your Controller and Services Webpack Encore support Caveats
      Symfony is no small Framework and will come with a price in terms of Memory Usage and added Overhead. To give you a taste I installed Tracy Debugger alongside to compare ProcessWire profiling with the included Symfony Webprofiler

      So in a fresh install Symprowire would atleast add another 2MB of Memory usage and around 40ms in response time, should be less in production due to the added overhead of the Webprofiler in dev env

      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.

      PageViewStatistic for ProcessWire is a module to log page visits of the CMS. The records including some basic information like IP-address, browser, operating system, requested page and originate page. Please note that this module doesn't claim to be the best or most accurate.
      Advantages
      One of the biggest advantage is that this module doesn't require any external service like Google Analytics or similar. You don't have to modify your templates either. There is also no Javascript or image required.
      Disadvantages
      There is only one disadvantage. This module doesn't record visits if the browser loads the page from its browser cache. To prevent the browser from loading the page from its cache, add the following meta tags to the header of your page:
      <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> How to use
      The records can be accessed via the Setup-menu of the CMS backend. The first dropdown control changes the view mode.

      Detailed records
      View mode "Detailed records" shows all visits of the selected day individually with IP-address, browser, operating system, requested page and originate page. Click the update button to see new added records.

      Cached visitor records
      View modes other than "Detailed records" are cached visitor counts which will be collected on a daily basis from the detailed records. This procedure ensures a faster display even with a large number of data records. Another advantage is that the detailed records can be deleted while the cache remains. The cache can be updated manually or automatically in a specified time period. Multiple visits from the same IP address on the same day are counted as a single visitor.

      Upgrade from older versions
      Cached visitor counts is new in version 1.0.8. If you just upgraded from an older version you might expire a delay or even an error 500 if you display cached visitor counts. The reason for this is that the cache has to be created from the records. This can take longer if your database contains many records. Sometimes it might hit the maximally execution time. Don't worry about that and keep reloading the page until the cache is completely created.
      Special Feature
      PageViewStatistic for ProcessWire can record the time a visitor viewed the page. This feature is deactivated by default. To activate open the module configuration page and activate "Record view time". If activated you will find a new column "S." in the records which means the time of view in seconds. With every page request, a Javascript code is inserted directly after the <body> tag. Every time the visitor switches to another tab or closes the tab, this script reports the number of seconds the tab was visible. The initial page request is recorded only as a hyphen (-).

      New in version 1.1.0
      A new feature comes with version 1.1.0 which offers to record user names of loggedin visitors. Just activate "Record user names" and "Record loggedin user" in the module settings.
      Settings
      You can access the module settings by clicking the Configuration button at the bottom of the records page. The settings page is also available in the menu: Modules->Configure->ProcessPageViewStat.
      IP2Location
      This module uses the IP2Location database from: http://www.ip2location.com. This database is required to obtain the country from the IP address. IP2Location updates this database at the begin of every month. The settings of ProcessPageViewStat offers the ability to automatically download the database monthly. Please note, that automatically download will not work if your webspace doesn't allow allow_url_fopen.
      Dragscroll
      This module uses DragScroll. A JavaScript available from: http://github.com/asvd/dragscroll. Dragscroll adds the ability in view mode "Day" to drag the records horizontally with the mouse pointer.
      parseUserAgentStringClass
      This module uses the PHP class parseUserAgentStringClass available from: http://www.toms-world.org/blog/parseuseragentstring/. This class is required to filter out the browser type and operating system from the server request.

      Inertia Adapter ProcessWire Module
      Hello! Long time no see.
      I created this module so you can use Inertia.js (https://inertiajs.com/) with ProcessWire.
      Description
      Inertia allows you to create fully client-side rendered, single-page apps, without much of the complexity that comes with modern SPAs. It does this by leveraging existing server-side frameworks.
      Inertia isn’t a framework, nor is it a replacement to your existing server-side or client-side frameworks. Rather, it’s designed to work with them. Think of Inertia as glue that connects the two. Inertia comes with three official client-side adapters (React, Vue, and Svelte).
      This is an adapter for ProcessWire. Inertia replaces PHP views altogether by returning JavaScript components from controller actions. Those components can be built with your frontend framework of choice.

      Hi all,
      we made a small module for sending SMS via Sms77.io. It supports sending to one and multiple users.
      You can download it from GitHub and follow the instructions on how to install it - it is quite easy. An API key is required for sending, get yours for free @ Sms77 and receive 0,50 €.
      Hope this helps somebody and we are open for improvement suggestions!
       
      Best regards
      André
