Hanna Code

[Macrura]

i tried using the shortcode module, and it is promising, and quite different than hanna codes; shortcodes allow you to have an opening and closing tag so you can enclose things within, which allows you to use them for things like tabs and accordions;

hanna code is very usable/flexible, but it doesn't know about things between each instance of itself (no opening/closing)...

also the shortcodes module doesn't allow for using more than 1 shortcode on a page.. i think it needs more work;

but it would be good if we could have a shortcodes module that works as well as the wordpress shortcodes, since there are still some rare use cases where shortcodes can be useful...

custom fields replaces and is superior for the most part to the concept of shortcodes, which is probably why the need has not come up much on PW.

And end users always mess up with shortcodes, like putting them in the wrong place in the RTE (like inside a heading), or forgetting to use the closing tag, and consequently break the layout on pages too easily...

I have never even considered using anything like Hanna code or shortcodes for our clients. I think what would make them usable would be making them appear as a block in editor, instead of plain text.

Actuall in my testing phase of PW - there are much less usecases for such little snippets because you could use simple a extra field or do prefered PHP direkt in the page template....but in other systems you only had some blocks or one Wysiwyg per pages and such snippets catch up some content or bring some logic to a wysiwyg the user doesn't have to think about it.

For example you could easy setup some Hanna codes and implement it fast via import on new different websites....reusable codesnippets are the usecase.

Iportant question if i wanna make them work in the template i have to call the process i think??

Next HannaCode from my testings is a simple sitemap:

//:Sitemap: creates a simple sitemap (Snippet find in the forum from soma)
//:Use: [[sitemap]]

Just import this one:

 Exactly my thought. And loaded/configurable per template, so that only hanna codes are shown that makes sence in that template.

Hi all

I hope there's someone here that can help me.. I've set up this site (www.sejero-festival.dk) on my localhost and Hanna Code works excellent.

However, and I've tried two different hosts now, when I deploy the site, the Hanna Code module fails miserably when I try to go to the setup part :

One of the hosts has the following specs:

PHP: 5.3.28

MySQL: 5.5.37

Does anyone have a clue what might cause this error?

[Franko]

For some reason I cannot get hanna code to work with php. I can get html to work just pine but php will not.

Here is my code

<?php

 

foreach($page->children as $product) {

 

    if($product->image) {

       // $image = $product->image->width(150);

        $img = "<img src='{$image->url}' alt='{$product->title}' class='flt-left-img' />";

    } 

    

    else {

     

        $img = "<span class='image_placeholder'>Image not available</span>";

    } 

 

    echo "

        $img

        <h3>{$product->title}</h3>

        <p>{$product->product_description}</p>

        <hr />

        ";

}

?>

 

 

 

The only thing that will output on the page is the product description but all other content from the body disappears.

 

Driving me nuts so any help would be great.

Is this still a problem? Does anything else work, i.e. is this the only place that's broken on this site?

Sounds like your database wasn't reachable at this point, but I'd imagine that causing issues elsewhere too. Unless, perhaps, it's somehow related to PHP's mysqli extension on that server (just about all core features have already been migrated to PDO instead).

For some reason I cannot get hanna code to work with php. I can get html to work just pine but php will not.

Here is my code

<?php

 

foreach($page->children as $product) {

 

    if($product->image) {

       // $image = $product->image->width(150);

        $img = "<img src='{$image->url}' alt='{$product->title}' class='flt-left-img' />";

    } 

    

    else {

     

        $img = "<span class='image_placeholder'>Image not available</span>";

    } 

 

    echo "

        $img

        <h3>{$product->title}</h3>

        <p>{$product->product_description}</p>

        <hr />

        ";

}

?>

 

 

 

The only thing that will output on the page is the product description but all other content from the body disappears.

Only weird thing I can spot in your code right away is that you've got $image = ... commented out, yet on the next line you try to use $image->url, which obviously won't be available here. I'm assuming that this was just something you did for testing and forgot there.

When you're saying that only output is the product description, it's coming from this Hanna Code snippet, right? Are you seeing empty <h3></h3> tags and then <p></p> tags with product description inside them and nothing else, or..?

I'm not really sure what you're referring to when you say that all other content from the "body" disappears; <body> element of your page, $page->body, or something entirely different? If you view the source of the page, is there anything weird there -- or in your log files, either in site/assets/logs/errors.txt or Apache logs?

[Franko]

oops I didn't mean to have that commented out. Its not in my code, but that was a copy that I forgot to uncomment. 

I am not seeing empty <h3> tags or <p> tags and yes the product description is coming from the hanna code. In fact the only thing that showing on the page is the product description from the hanna code. Everything else disappears including all paragraphs and everything else in the textarea $page->body. There is nothing weird in the source. It has to be the way this php is whitten I think because I am using other php for another hanna code and it works.  

this is the other code that works

<?php foreach ($page->children() as $c): ?>

<li><a href="<?=$c->url;?>"><img src="<?=$c->listImage->url;?>" alt="<?=$c->listImage->description;?>" width="100" height="100"> <?=$c->listImage->description;?> <span>View More</span></a></li>

<? endforeach; ?>

Yeah it's still a problem. :-(

And now I've tried it on another host with same result. The only two places I've succesfully gotten the Hanna Code module to work were on localhost (yay) and on my Digital Ocean Droplet...

I guess I'll let the owner of the site know, that he can't get that module on the two host masters he wished for.

[cstevensjr]

First problem I noticed, two people are asking two separate questions at the same time.

For @kasperwf,

 Hi all

 

I hope there's someone here that can help me.. I've set up this site (www.sejero-festival.dk) on my localhost and Hanna Code works excellent.

However, and I've tried two different hosts now, when I deploy the site, the Hanna Code module fails miserably when I try to go to the setup part :

  One of the hosts has the following specs:

 

PHP: 5.3.28

MySQL: 5.5.37

 

Does anyone have a clue what might cause this error?

 

On your localhost (that is working), what are the following:

ProcessWire version

PHP version

MySQL version

Apache version

Then, what are the same information for both hosts that you have have tried?  Having that information, will allow someone to truly be of help to you.  Thanks.

My localhost:

PHP version: 5.4.22

MySQL version: 5.6.10

Apache: Apache/2.2.26 (Unix)

The information for the hosts that doesn't work is the one I wrote earlier. Seems like they both use the exact same setup (as the other, not like mine, the working server). :-I

The info for my VPS that also work is:

PHP: 5.5.9-1ubuntu4

MySQL: I really don't know, because I obviously secured it too well, and I can't even mysql -v it. But it was last month, and it was the newest version, so, yeah.

Apache: Apache/2.4.7 (Ubuntu)

[alejandro]

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. 

Hello,

I fail to make it work. I'm using PW version 2.4.4. TemplateFile.php lines 156-158 are correctly updated:

	public function getArray() {
		return array_merge($this->fuel->getArray(), parent::getArray()); 
	}

My Hanna code is as simple as:

[[page-title]] :

<?php
echo $page->title;

The structure is as follows:

Page texts, with title "Texts" -> Field "Text 1" (Textareas ProField)-> "Some text... " . [[page-title]]

Page product name, with title "Product name"-> API reference to Field "Text 1"

Outputs "Some text... Texts"

Should be "Some text... Product name"

I think it should work, but can´t see the problem. The textareas field has Hanna Code Text Formatter applied.

Thanks, 

[Joss]

I think I am getting caught out by scope - well, I know I am.

I have some text on a page other than the one I am looking at, and I am drawing it in with get()

That text has a hanna code in it that simply echos the page title.

The problem is that it is echoing the page title of the page the code originates from and not from the page I am looking at.

How do I do this so that it gets my current page title, not the page where the text originates from?

[Joss]

ummm ... I am halfway there.

by using this for the php for my hanna code <?php echo wire("page")->title; ?> I now get the current page title.

However, I am not getting the rest of the text.

So:

This is my [[pagetitle]] you can see

Is just printing out the page title, not the rest of the words.

[Soma]

You don't happend to replace sorounding p tags and the hanna code is inside the text paragraph?

[Joss]

Hi Soma, no, I have the replace bit turned off.

I think it is because the textarea that supplies the text, complete with the hanna code reference, is originating on another page.

I am calling it into my template with:

<? echo $pages->get("/servicing/")->service_model_default_text; ?>

Now, if I use a different code, one that pulls the info from a specified field in a specified page, that works fine.

For instance, a code that is:

echo "<span class='phonenumber'>Call {$pages->get("/settings/")->site_phone}</span>";

But if I try and call something from the current page, it goes wrong.

So if I used the code:

echo $page->title;

Simply prints out title of the page where the text originated, but not the rest of the text. if I use wire() it prints out the current page title, but again no text. Debug is not showing errors.

[Soma]

Sorry can't really follow what you're doing. Mostly confused why you'd need hanna code at all just for a page title?

[Joss]

Basically I have a huge lump of default text in a separate page that is pulled into about 100 pages or so.

The default text needs to pick up values from those pages - product name, price and so on - that will be part of that long default text. The page title is just one of those values.

The easiest way I could see to do it (and easy for the client to understand) was to use bits of hanna code within the text.

[Soma]

I have hard time following what code is where and what doesn't work.

[Joss]

Sorry, Soma, I should have explained it better.

I have a page called services that has a CKEditor field called service_model_default_text

It contains, for instance, "we can service your [[model-name]]"

The code for the [[model-name]] hanna code is 

<?php echo wire("page")->title; ?>

I have the replace surrounding tag set to "no" and it is type PHP

I have another page called Audi. In the template for that page I get the field from the services page.

<?php echo $pages->get("/servicing/")->service_model_default_text; ?>

The idea is that the hanna code is replace with the page title from the audi page so that the final result is:

We can service your Audi.

Unfortunately, the hanna code system does not seem to be able to do that, it prints out the page title fine, but not the rest of the text from the field.

However, if I change the hanna code to another one I have, [[phonenumber]], which takes its input from a field on a completely separate page, it works fine.

Confused!

[Soma]

I tested something like this in latest dev and 2.4 installation, works fine. I can't see any text not outputting.

Default site. Added hanna code formatter to body field. In /templates/ page in the body I place a hanna code inside text [[model-name]] and output that text on the About page. 

Hanna code 

<?php
echo wire("page")->title;

In template basic-page.php

echo $pages->get("/templates/")->body;

The hanna tag gets replaced with the page title and the surrounding text is still there.

[Joss]

Damn!

I wonder what I have got that is messing it up?

I think I will strip the entire template out apart from the get line and see what happens

[Joss]

Do those two pages, the one you have the body field and the about page, use the same template?

I just emptied the template file, but it still is not working properly.

I noticed that when I save and test the hanna code, inside the dotted box it just says Hanna Code

No idea why.

[Soma]

Yes those two pages have same template. It doesn't matter what template. I've never used the save and test. But I think you would see the current admin page title if anything at all.

[Joss]

hmm ... so something is not right. 

With the other hanna code, the one that points to a telephone number, in test it shows the telephone number.

I have tried deleting the hanna code instance, and adding a new one and it is the same problem.

The only other thing is that they are on different tree levels - the page that has the text in it is a child of home, the other page, the Audi page, is its grandchild. But I dont think that should be a problem.

I am a bit lost on this, to be honest, and it has brought the project to a shuddering halt
