Hanna Code

[LostKobrakai]

One thing I noticed, I think there should be a space after "echo". Also I'm personally not keen on multiline strings. I don't trust them to work. I've also added a test for how much teams are really found, which is what I would check first. If there are multiple teams found, but only one is displayed you can say for sure somethings wrong with your snippet.

<?php
$teams = $pages->find("template=team_member,limit=10");
// Just for debug purposes
echo "It's ".count($teams)." teams.";
$out = "";
foreach ($teams as $team) {
  $out .= "<div class=\"team-wrapper\">";
  $out .= "<h2>{$team->title}</h2>";
  $out .= "<h3>{$team->team_role}</h3>";
  $out .= $team->body;
  $out .= "</div>";
}
echo $out;
?>

That correctly displays within HannaCode itself (Save and Test) and counts 9 teams.

Once the HC tag is added to the Body field, I get a single team biography. No name or job role either.

I've seen this on peoples code samples before and always wondered why they were using this. Thanks for the tip

Does it show "It' s 1 teams." ? Or does it even show this line? I'm just curious if the culpit is somehow in the foreach loop or earlier in loading $teams. 

[Peter Knight]

Your code outputs

It's 9 teams

...which is the correct amount BTW

[LostKobrakai]

So it seems the culpit is somewhere in the foreach loop, which is not what I expected Did you try the ultra failsave of using concatination instead of curly braces and single quotes for the class? I really don't see an error, but just to try it. Maybe var_dump $teams / $team inside of the loop, so check if something is messing with them.

does team body have hanna code formatter enabled?

[Peter Knight]

does team body have hanna code formatter enabled?

Yes. One of the first things I checked too after making that error last time

I'm going to deconstruct things tomorrow. Start off with calling just a single field in a basic template.

Will report back

[Macrura]

does it work if you disable the hanna code on that? i'm guessing from what you are saying, no...

[hwmaier]

If {team->body} has hanna code formatter enabled, then it will not work as Hanna Code 1.9 does not support recursive Hanna code processing. Refer to my earlier post.

Remove the {$team->body} statement from your code snippet and check the result whether it then outputs all 9 members. Once you see that working, try using the patched version of Hanna Code I submitted on Github.

[LostKobrakai]

I've a feature request. As I can assign users of ProcessWire the right to view/list hanna codes it would be nice to be able to incorporate a description field, where I can add small explanations for each code. This way the list/view permission would be more useful on it's own. 

This could maybe later be incorporated in something like a small dropdown underneath hanna code textfields.

Hey hwmaler

That works so I can confirm it's an issue with recursive Body fields.

Peter,

Thanks for testing and confirming the fix. I will add your confirmation to the Github issue list notes and hopefully this fix is adopted at some stage by Ryan into the main release.

Should clarify that removing the body field worked.

I wasn't sure how to get your own github version running. Tried manually adding your changes and that didn't work.

[gerritvanaaken]

I use PHP-based Hanna Code snippets for embedding certain fields from certain pages on other pages. Now I stumbled upon the fact that you cannot render fields within a Hanna Code when the Hanna Code Textformatter is applied to that field. The result is a broken output where only a small part of the page is being rendered.

How can I achieve those "recursive Hanna Codes"?

[LostKobrakai]

Have a look at this pull request: https://github.com/ryancramerdesign/ProcessHannaCode/pull/10

[gerritvanaaken]

Wow, thanks, will have a try. Will report here if it works!

–––– works as exspected!

Hi all,

if I write the following code in one of my template files:

$result = $db->query("SELECT id, name FROM pages");
while($row = $result->fetch_array()) print_r($row); 

It works and prints a list of all my pages.

If I write the same code in a "php hanna code", I get no result from the query.
Is there any reason, that $db is not working in hanna codes?

thanx for your help

I took your code and created a php Hanna Code from it.  I created a template (clone of basic-page) and renamed it "test1".  The body field has the hanna code text formatter assigned to it.  Here is a sample of the output:

The code is working or is there something else you actually meant?

[thoha]

Thank you cstenvsjr,

that was the output I want to see.
Now that I saw that it was no hanna problem, I found the solution. There was a little include(..) before the posted lines that was responsible for the error.

you made my day

Question?

Is it possible within a certain hanna code there is also a hanna code include...?

[LostKobrakai]

Recursive hanna codes is mentioned already a few time in this topic. There's an open pull request on the github repo, that adds support for that, but the official release doesn't have that right now.

[Marty Walker]

I'm trying to use this simple hanna code in a CKEditor field (using PW 2.6.1):

<?php
	echo "<ul>";
	foreach ($pages->get('/contact-us/')->children as $offices) {
		echo "<li><h2>{$offices->title}</h2>{$offices->body}</li>";
	}
	echo "</ul>";

The 'contact-us' page has 4 child pages with the office info. If I add the above code to my template it works fine but if I add the HC to my body field it strips most of the content from that body field out. The only textformatter I have on that body field is the HC one. The 'Save & Test' shows the results fine so I have no idea what I'm doing wrong.

edit: for some reason if I remove the '$offices->body' from my echo it works.

edit 2: just read the previous pages and realise now it's a bug.

Sorry folks if I missed this in the docs and threads.., but is there a way to get a regular PW template to o/p a Hanna, sort of like a Hanna being an include?

$out .= "<div id='clientCard'>";
	$out .= "<h2>Client card</h2>";
	$out .= wire('modules')->get('[[client_card_intro]]');
$out .= "</div>";

I am trying to see if I can do this so I can build a DRY (don't repeat yourself) collection of items that I can use either in the Admin in a rich text field via the usual [[the_name_of_the_hanna]] or from the API in a template via a correct version of the code above.

Thanks for any comments, cheers, -Alan

Edit:

It looks as if Ryan recommends this is not done (if I read this right) for reasons of security.

[Macrura]

yup, just include the path to the php file in your hanna code;

<?php

include($config->paths->templates . "hannas/myhanna.php");

then you can include that same file form a template, or use as hanna code.

Fab! Thanks Macrura
