Hanna Code

Recommended Posts

Hi,

first of all: I think the addition of this particular module is great! I can think of quite a few itches I could scratch with that.

Something I've been wondering about: How would I go about accessing specific repeater fields with the Hanna Code.

Say for example I have a repeater including a Text field, a Date and a Price.

I'd fill the text Field with

Come on the [[date]], bring [[price]]$ in small used bills. Thank you for your cooperation.

The frontend should obviously render this as

Come on the 4th of July, bring 50$ in small used bills. Thank you for your cooperation.

If Text, Date and Price where just page fields, this would be pretty obvious. However for them being fields inside a repeater I think there's something like the jQuery siblings selector needed, but I don't see anything like that in the api documentation.

Any input on this would be very much appreciated :-)

Is there any way to get Hanna code to render within Hanna code?

I've got two tags.

[[tooltip]] and [[info]]

What I'm trying to do is this:

[[tooltip text="[[info]]" tooltip="test"]]

And then using the following snippet within the [[tooltip]] hanna code:

$hanna = wire('modules')->get('TextformatterHannaCode');
echo "<a class='tooltip' href='#' title='{$tooltip}'>".$hanna->render($text)."</a>";

This doesn't seem to be working unfortunately. Any ideas on how to make this work?

[[info]] just echos out an img tag.

Cheers

@Sinmok,

From your example you are trying to add a tooltip.   I don't know what front-end framework you are working with on your website, however with Zurb Foundation 4 you can do a tooltip using Hanna Code as follows:

<span data-tooltip class="has-tip" title="Tooltips are awesome, you should totally use them!">extended information</span>

Your Type would be Text/HTML.

Then you just add the Hanna Code in a field that supports Hanna Code.

This may not answer your specific request for having Hanna Code within Hanna Code, but it does show how a tooltip can be added using Hanna Code.  Good Day.

This turned out to be an issue with the order of variables returned by core TemplateFile::getArray. It was doing an array_merge which gave preference to API variables, preventing them from being overwritten. Maybe that's a good thing in general, but I don't think we want that limitation. I went ahead and changed it in dev. Now it gives preference to local variables, which enables Hanna Code to provide the behavior it was supposed to. 

I think I've found another issue related to the use of $page in a Hanna code: if the field containing the hanna code is in a repeater, $page seems to point to something internal to the repeater instead of pointing to the page containing the repeater field.

Example with a hanna code echoing the page id:

// in a field directly in the home page
echo $page->id;
--> 1

// in the field from a repeater on the same home page
echo $page->id;
--> 1060

From what I understand by looking at the repeater module source code, repeaters are implemented with pages. So the observed behavior is probably a side effect of this.

Any idea of how to fix this ?

@jean-luk

Yes repeaters are in fact internal pages, so doing the following should help (not tested):

if ($page instanceof RepeaterPage) {

$id = $page->parent->id;

} else {

$id = $page->id;

} 

echo $id;

@slkwrm
 
Thanks for the hint.
 
Actually it turns out that the repeater page's parent is not the page where the repeater field is, but this page can be got by calling the method getForPage. So the correct code is:

$containerPage = $page;
if ($page instanceof RepeaterPage) {
   $containerPage = $page->getForPage();
}

// can be checked with
echo $containerPage->id;

I added this container page calculation at the right place (I hope!) in TextformatterHannaCode.module and the repeater field case now seems to work for hanna codes.

Finally I'm not sure about the best way of handling this hanna-code-inside-reapeater-field case…
 
On one hand, a naive hanna code writer like myself would expect $page to refer to the user-visible field container page;
 
On the other hand, having a reference to the current "repeater page" can be useful in many cases, like this one:

If Text, Date and Price where just page fields, this would be pretty obvious. However for them being fields inside a repeater I think there's something like the jQuery siblings selector needed, but I don't see anything like that in the api documentation.
 
Any input on this would be very much appreciated  :-)

 
Maybe a solution would be to have two different PHP variables accessible from within the hanna code, where the one referring to the repeater page would be null if the current field is not part of a repeater.
 
Easy to implement, but, as always, not so easy to keep it consistent with the rest of the PW API. 
 
Ryan, your opinion about this?

Got a feeling this is a server issue but I'm getting an error I can't seem to recover from after saving a simple HTML code:

Method Sanitizer::entities does not exist or is not callable in this context

I can't even load the Hanna Code config screen - even if I try to ununstall/install it again. It hasn't written any files to /site/assets/cache/HannaCode/ either.

I'm running PW 2.2.9 on PHP version 5.2.17. Stuck! :)

Marty, not sure why there is no sanitizer entities method there. Maybe we didn't have it in 2.2, I don't recall. Try replacing your wire/core/Sanitizer.php file with a fresh copy. It should be fine to take the one from 2.3 or 2.4.

Jean-luc, glad to see you found the getForPage method. This is exactly the way that repeater pages are meant to refer to their containing page, whether in a Hanna code or elsewhere.

Perhaps this has come up already in this thread, haven't read it all, and I don't want to be a nay-sayer, but if it's primarily aimed at super users i.e. us devs, why have a GUI at all? Why not leave out the whole visual stuff and have HannaCode parse the text and search for template files (or template file in a subdir like templates/hanna) with the HannaCode name.

[[my-hanna foo=bar]] looks for templates/hanna/my-hanna.php and passes the params like with any other regular template. This way we can edit our hanna-codes in our IDE or text editor of choice with all the highlighting and we can push it into version control, no need to fiddle around with exports or imports between installations.

Am I missing something?

@owzim, just throwing in some possible reasons:

  • Not all superusers are developers. Whether or not that's a good thing, Hanna Code allows people with no access to actual code to add features that would normally require such an access -- or at least some way to edit files on disk.
  • It's not just about PHP code. Tiny snippets of random HTML or JS can be easily added without having to add files for those too.
  • Hanna Code provides easy way to quickly sketch and test code snippets you're not going to need in the longer term. This is also handy when working in an environment where same site exists on multiple locations sharing database but not code (in which case moving a snippet of code in disk from one location to another would typically require extra steps).

That being said, I really believe that Hanna Code would benefit from more fine-grained access management.

This could mean three different permissions: hanna-code-html, hanna-code-javascript and hanna-code-php. Or perhaps just two -- hanna-code to add all sorts of snippets and another, limited permission for creating only HTML + JS snippets.

The way it is right now, I can't imagine giving a client access to creating their own Hanna Code snippets, but if it allowed me to limit that access to less destructive features this module would have a lot more potential.

Edit: almost forgot to mention that of course you could already add the sort of thing you're talking about, though the syntax would be slightly different (filename as a variable). GUI doesn't make that impossible and you don't really have to use it unless you want to :)

...sorry don't read the whole threat, too

short questions about HannaCode:

-> Is ther a Overview/Post with contributed examples for "Hannas"

-> If yes who can i contribute

i've got a few of this little helpers from another system (the CMS Argos and i used and contributed before find PW) there was an Admintool that's called "Droplets". There exists a "Dropletgallery" and we had a WYSIWYG Plugin for choose one for the editor to use.

Best Regards mr-fan


Example for a "dropletCode" could this used in Hanna as it is or need special threatment or changes...

//:genQR creates QR Codes with google Charts API
//:Use: [[genQR?size=150&link=http://what-ever.com]]
 
 Parameters:
 $size - default is 200 px
 $link - default if nothing set is google.com
 
if ( !isset($size) ){    $size = 200; };
$width = $size;
$height = $size;
if ( !isset($link) ){ $link = "http://google.com"; };
$url = urlencode(".$link."); 
return "<img src=\"http://chart.googleapis.com/chart?chs={$width}x{$height}&cht=qr&chl=$url\" />";

just for the starting point - i've more like this to share if it's usefull :rolleyes:


a starting point coudl even be a gist repo?

@ozwim - not sure if you already know about this, but i follow Soma's suggestion and have a folder called 'hannas' and then keep all the hanna codes there; and then using this in the hanna code itself:

include($config->paths->templates . "hannas/some-hanna-code.php");

@mr-fan - that's great - we should try and setup a place to share hanna codes... maybe github? I have a lot of examples also

Mr-fan, you're right, the PW Hanna system seems to be very like the "WB-droplets" we are familiar with, coming from WebsiteBaker. There is even an integration with the editor, called HannaCodeHelper. Check it out in the Modules repo.

Ok first try seems to work with given atr in Hanna Code like:

[[genQR size="400" link="http:\\google.com"]]

but the fallback option would be nice to have a QR Code from the current Link - May used for events or articles....

heres my code for first hanna experiments may i missed the wrong API handling??

<?php 

//:genQR creates QR Codes with google Charts API
//:Use: [[genQR?size=150&link=http://what-ever.com]]
//
// Parameters:
// $size - default is 200 px
// $link - default if nothing set is google.com
 
if ( !isset($size) ){    $size = 200; };
$width = $size;
$height = $size;
if ( !isset($link) ){ $link = $page->httpUrl; };

echo "<img src=\"http://chart.googleapis.com/chart?chs={$width}x{$height}&cht=qr&chl=$link\" />";
//  to testing link url echo "<p>$link</p>";

like written it works with a link="some.link" and if not it doesn't take the current url $page->httpUrl;
:(

for a repo would be a cool place to have something like a hanna code gallery or overview of some snippets...??

like in our old system (argos and mine) there was a snippetgallery for this: http://www.websitebakers.com/pages/droplets/official-library.php

maybe there is some inspriation for PW HannaCode or if i getting more familiar with PW i can port some for usage with PW.

To make PW more user friendly (especially for non-coders) I think it would be best to create a Hannacode subsection in the Modules section on the regular PW site. Personally I think regular users should not be send to some Github page, as it is far too technical, intimidating, and therefore unfriendly environment for non-coders. Hannacodes are (as far as I can tell, as a newer than new newbie) ready to use code snippets and as such could be offered on the regular site.

I am not quite sure whether you are having problems with your code working or not. It works perfectly for me if I don't define a link - it defaults to the current page and if I do define it goes to that link. Can you tell us exactly what isn't working and what the link is instead?

Effectively they are/do the same thing. I think Ryan got the name and inspiration from WP's Hana code.

@Argos: PW is much more Coding like our older System but for the frontend it isn't that hard to use it seems to me. For the Frontend it depends an procedural Coding combining with the PW API it's really amazing - Backend and process are mostly OOP PHP and a little bit more devwork

so i don't know what is wrong:

[[genQR size="200"]]

and same code as above but with echo the $link give me a screen like this (second QR is emty with no $link is given)

(....system is PW 2.4 clean install with some testaddons and the basic-site profil)

thanks for take a look

I am at a loss for why it isn't working for you. Not that it matter, but here is a slightly cleaned up version of your code:

if (!isset($size)) $size = 200;
if (!isset($link)) $link = $page->httpUrl;

echo "<img src='http://chart.googleapis.com/chart?chs={$size}x{$size}&cht=qr&chl=$link' />";

You had unnecessary curly braces and extra semi-colons and also since these are square, there is no need to define the width and height separately. If you wanted you could even make it a one liner:

echo "<img src='http://chart.googleapis.com/chart?chs=" . (isset($size) ? $size : 200) ."x" . (isset($size) ? $size : 200) ."&cht=qr&chl=" . (isset($link) ? $link : $page->httpUrl) . "' />";

Although you do sacrifice a little readability.

One other quick thing - in your google.com example, you are using backslashes instead of forwardslashes - probably just a typo :)

I'm sorry, I wasn't clear enough. What I meant was, what is the difference between the modules "Hannacode" and "Shortcode"? These are two different shortcode type modules.

Oh right - sorry I misunderstood. Both provide similar functionality, although I haven't actually used Nico's shortcode module, so not completely sure on the differences. I guess my advice would be to experiment with both and see which best provides you the functionality you need.

If it be ok - from the modside we could make a new Threat with only HannaCode Examples as Posts - i would sort them into groups in a first post? If this is welcome?

      Repeater Images
      Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc.
      When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing.
      Screencast

      Installation
      Install the Repeater Images module.
      Setup
      Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration
      Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module.
      Image uploads feature
      There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field.
      To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position.
      It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field.
      New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved.
      Tips
      The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height})

      Hello There Guys.

      I am in the process of getting into making my first modules for PW and i had a question for you PHP and PW gurus in here.

      I was wondering how i could use an external library, lets say TwitterOAuth in my PW module.
      Link to library
      https://twitteroauth.com/

      Would the code below be correct or how would i go about this:
      <?PHP namespace ProcessWire; /* load the TwitterOAuth library from my Module folder */ require "twitteroauth/autoload.php"; use Abraham\TwitterOAuth\TwitterOAuth; class EyeTwitter extends WireData,TwitterOAuth implements Module { /* vars */ protected $twConnection; /* extend parent TwitterOAuth contructor $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token_secret); */ public function myTwitterConnection ($consumer_key, $consumer_secret, $access_token, $access_token_secret) { /* save the connection for use later */ $this->twConnection = TwitterOAuth::__construct($consumer_key, $consumer_secret, $access_token, $access_token_secret); } } ?> Am i on the right trail here or i am barking up the wrong tree?
      I don´t need a complete solution, i just wonder if i am including the external library the right way.
      If not, then give me a few hint´s and i will figure it out.

      Thanks a bunch.

      Hello,
      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version (has been tested up to v3.3), add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "http://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      Usage
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
       
      Download
      PW module directory: http://modules.processwire.com/modules/auto-fb-post/ Github: https://github.com/kastrind/AutoFbPost   Note: Facebook SDK for PHP is utilized.

      FieldtypeRuntimeMarkup and InputfieldRuntimeMarkup
       
      Modules Directory: http://modules.processwire.com/modules/fieldtype-runtime-markup/
      GitHub: https://github.com/kongondo/FieldtypeRuntimeMarkup
      As of 11 May 2019 ProcessWire versions earlier than 3.x are not supported
      This module allows for custom markup to be dynamically (PHP) generated and output within a page's edit screen (in Admin).
       
      The value for the fieldtype is generated at runtime. No data is saved in the database. The accompanying InputfieldRuntimeMarkup is only used to render/display the markup in the page edit screen.
       
      The field's value is accessible from the ProcessWire API in the frontend like any other field, i.e. it has access to $page and $pages.
       
      The module was commissioned/sponsored by @Valan. Although there's certainly other ways to achieve what this module does, it offers a dynamic and flexible alternative to generating your own markup in a page's edit screen whilst also allowing access to that markup in the frontend. Thanks Valan!
       
      Warning/Consideration
      Although access to ProcessWire's Fields' admin pages is only available to Superusers, this Fieldtype will evaluate and run the custom PHP Code entered and saved in the field's settings (Details tab). Utmost care should therefore be taken in making sure your code does not perform any CRUD operations!! (unless of course that's intentional) The value for this fieldtype is generated at runtime and thus no data is stored in the database. This means that you cannot directly query a RuntimeMarkup field from $pages->find(). Usage and API
       
      Backend
      Enter your custom PHP snippet in the Details tab of your field (it is RECOMMENDED though that you use wireRenderFile() instead. See example below). Your code can be as simple or as complicated as you want as long as in the end you return a value that is not an array or an object or anything other than a string/integer.
       
      FieldtypeRuntimeMarkup has access to $page (the current page being edited/viewed) and $pages. 
       
      A very simple example.
      return 'Hello'; Simple example.
      return $page->title; Simple example with markup.
      return '<h2>' . $page->title . '</h2>'; Another simple example with markup.
      $out = '<h1>hello '; $out .= $page->title; $out .= '</h1>'; return $out; A more advanced example.
      $p = $pages->get('/about-us/')->child('sort=random'); return '<p>' . $p->title . '</p>'; An even more complex example.
      $str =''; if($page->name == 'about-us') { $p = $page->children->last(); $str = "<h2><a href='{$p->url}'>{$p->title}</a></h2>"; } else { $str = "<h2><a href='{$page->url}'>{$page->title}</a></h2>"; } return $str; Rather than type your code directly in the Details tab of the field, it is highly recommended that you placed all your code in an external file and call that file using the core wireRenderFile() method. Taking this approach means you will be able to edit your code in your favourite text editor. It also means you will be able to type more text without having to scroll. Editing the file is also easier than editing the field. To use this approach, simply do:
      return wireRenderFile('name-of-file');// file will be in /site/templates/ If using ProcessWire 3.x, you will need to use namespace as follows:
      return ProcessWire\wireRenderFile('name-of-file'); How to access the value of RuntimeMarkup in the frontend (our field is called 'runtime_markup')
       
      Access the field on the current page (just like any other field)
      echo $page->runtime_markup; Access the field on another page
      echo $pages->get('/about-us/')->runtime_markup; Screenshots
