Does width() or size() not work with Hanna Code?

I've something like this:

<?php
$out = '';

if ( isset($ma) ){ 

    //get mitarbeiter
    $mitarbeiter = $pages->get("template=part_ma,shortcut=$ma");
    if ($mitarbeiter) {
        
        //get the original image
        $image = $mitarbeiter->mitarbeiter_bild;
        //get thumbnail
        $thumb = $image->width(90);
        
        //render mitarbeiter
        $out .= '
                <div class="b-author">
        			<p>'.$mitarbeiter->title.'<br><span>'.$mitarbeiter->headline.'</span></p>
        			<img alt="'.$mitarbeiter->title.'" src="'.$thumb->url.'">
        		</div>
        		';
    }
} else {
    $out = 'noting there!'; 
}

echo $out;

works in a template but with Hanna code i get

Call to a member function width() on a non-object

don't know why - if i remove width() or size() image is working but this is not good since it is the wrong size...

Best Regards mr-fan

(normal single image field without something special - PW dev 2.6.19)

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.

+1 for the bug with recursive/nested hanna code textformatters, +1 for the github pull request which does fix the issue, and +1 for having it integrated to the official release

cheers

Hi, 

I wrote some simple Hanna code for outputting external links given an identifier and a link text. The actual link URL is stored in a repeater field along with a unique id.

Example usage:

[[link id=myid text="My Great Link"]]

Default attributes:

id
text
target=_blank
 
Code:
<?php

$link = $pages->get("template=repeater_links, identifier={$id}")->link;

echo "<a href='{$link}' target='{$target}'>{$text}</a>";

?>
The problem is that the value of the text attribute ("My Great Link" in the example above) gets cut off at the first whitespace ("My). 
 
From the module description I learnt that in order to pass a string containing blank characters, all I needed to do was put quotes around the attribute. However, it seems I am still missing something, and it would be great if someone could point me to the right direction.
 
Cheers, 
 
Stefan

Just tested and works fine here.

Maybe you take a look at other textformatters or try to change your code....here is the changed example i used to test on normal pages:

<?php

$template = "basic-page";

//search for special content
//$link = $pages->get("template=repeater_links, identifier={$id}");

//seach normal pages
$link = $pages->get("template={$template}, id={$id}");

//check if $link has a page for output
if ($link != "") {
    echo "<a href='{$link->url}' target='{$target}'>{$text}</a>";
}

@mr-fan

You solved the issue!

Thanks to you mentioning other textformatters I took a closer look at the body field, where the Hanna code was to be applied to - only to find out that the HannaCode textformatter was applied after the textile textformatter. Switching both resolved the issue immediately!

Best regards,

I am trying to create a hanna code [[side-menu]] to display a static menu. If I put the menu html in the hanna file directly it works fine. What I'd want though is to keep the menu html in a external file and just let the hanna code include it. So in my hanna code I put:

<?php

include('/site/templates/mysidemenu.php');

?>

This does not work - no errors just no output. The menu in mysidemenu.php is just plain html. Not sure what I am missing on this. 

RESOLVED: I determined that if I write the include like this it will work as expected:

include($config->paths->templates.'/mysidemenu.php');

Surprised though that I didn't see a file not found on the first approach.

I've seen this issue before on the forums.  I believe you have to use $config->paths->templates as part of your include.

Alternatively, if you have a page that utilizes mysidemenu.php as its template file you could just use render, like:

echo $pages->get("/path/to/page/")->render(); // add ['prependFile'=>''] inside of render if necessary

Wheren't those hanna code snippets actually stored as files? So you should be able to edit those directly.

Yes that's true. However I may extend the hanna code with a parameter to allow me to load different menu files with it or possibly load a menu based on the current page it is on.

I like this approach. HannaCode is an integral part of most of my sites but I find it easier to upload chunks of code via my FTP editor.

And by using a proper text editor, I have better syntax highlighting etc. 

I put them in a sub-folder just to keep them separate from main templates

include($config->paths->templates.'/chunks/get-client-logos.php');

Only problem I have is ye olde recursive Body not working unless I manually update the Module.

Anyone have tested hannacode in PW3?

When I use [[image src=pic1.jpg]] in PW2 — Hanna trim quotes and  sends pic1.jpg to src var, but in PW3 it includes "" to string and looks like src=>"pic1.jpg", so in the rendered code I get _quot_pic1.jpg_quot_

p.s. [[image src=pic1.jpg]] and [[image src=pic1.jpg]] works fine but...

Using the following code in Hanna code always evaluates as TRUE:

if ($page->id == "1187") {
    echo $page->id;
}

or

if ($page == $pages->get("1187")) {
    echo $page->id;
}

returns true and prints out 1187 no matter what page I run the code on  ??? 
I should be able to use $page and $pages in Hanna code without problem or did I misunderstood something?
Thanks

The $page API variable available to your Hanna code represents the page where the Hanna code exists. It is possible for this to be different from wire('page'), which represents the page that originated the request.

http://modules.processwire.com/modules/process-hanna-code/

I am guessing your HC exists on the page with ID 1187? So it will always evaluate to true. Use wire('page') to refer to pages originating the request.

I have some trouble with an "unstable" Hanna Code at my 2.6.1 site. Whenever I edited a php code, I was redirect to a 404 front end error. So I installed Hanna Code afresh. But also when I am trying to add a new php code, I get the error. Creating a html code works.

Any ideas?

(I tried with debug mode on, but got no notifications.)

Kongondo, thank you, that was it indeed. I overlooked that part. Sorry for only reacting now, I keep forgetting to follow the topics and just assume I'm added automatically. ;)

Anyone else got this problem? I tried on multiple installations of ProcessWire. Always when trying to create (or save an existing) Hanna Code in PHP, I'm throw and error. I.e. this one:

Forbidden
You don't have permission to access /processdisplay/processwire/setup/hanna-code/edit/ on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.

That sounds like wrong directory/file permissions.

That might be! I checked on a local installation as well, no problems there. Probably some permissions being mixed up on copy to a live site, which most of my pages have been that I have tested on.

Any idea what specific folder or file I could check for this? I've been looking here and there now, without luck.

Status: I have found that my described issue is related to my current host. I set up a test on my old host and it gave me full access to edit/create PHP with Hanna Code again. I have not pinpointed exactly what requirements I need on my current host.

You could check with your host to see if they are running mod_security.

I just struck the same 404 problem when I use an include in my Hanna PHP code. My host lets me disable mod_security via htaccess, and sure enough when I disable it the 404 problem is gone.

      WHY?
      This module was built to fill the gap between simple $pages->find() operations and complex SQL queries.
      The problem with $pages->find() is that it loads all pages into memory and that can be a problem when querying multiple thousands of pages. Even $pages->findMany() loads all pages into memory and therefore is a lot slower than regular SQL.
      The problem with SQL on the other hand is, that the queries are quite complex to build. All fields are separate tables, some repeatable fields use multiple rows for their content that belong to only one single page, you always need to check for the page status (which is not necessary on regular find() operations and therefore nobody is used to that).
      In short: It is far too much work to efficiently and easily get an array of data based on PW pages and fields and I need that a lot for my RockGrid module to build all kinds of tabular data.

      Basic Usage

      Hello for all,
      ConfigurationForm fieldtype module is one my experiment from 2016.
      Main target to build this module was to store multiple setup and configuration values in just 1 field and avoid to use 1 db table to store just single "number of items on page", or another db table to store "layout type" etc. Thanks to JSON formatted storage this module can help you to reduce number of PW native fields in project, save DB space, and reduce number of queries at front-end.
      Install and setup:
      Download (at the bottom ), unzip and install like any other PW module (site/modules/...). Create some filed using this type of field (ConfigurationForm Fieldtype) Go to field setup Input tab and drag some subfields to container area (demo). Set "Name" and other params for subfields Save and place field to templates ("Action tab") How to use it:
      In my case, I use it to store setup and configurations values, but also for contact details, small content blocks... (eg. "widgets").
      Basic usage example:
      ConfigForm fieldtype "setup" has subfields:
      "limit", type select, option values: 5, 10, 15, 20
      "sort", type select, option values: "-date", "date",  "-sort", "sort"
      // get page children (items) $limit = isset($page->setup->limit) ? $page->setup->limit : 10; $sort = isset($page->setup->sort) ? $page->setup->sort : '-sort'; $items = $page->children("limit=$limit, sort=$sort");  
      Screenshots:


       
      Notes:
      Provide option to search inside subfields Provide multilanguage inputs for text and textarea field types Provide option for different field layout per-template basis Do not place/use field type "Button" or "File input" because it won't works. Please read README file for more details and examples Module use JSON format to store values. Text and textarea field types are multilanguage compatible, but please note that main target for this module was to store setup values and small content blocks and save DB space. Search part inside JSON is still a relatively new in MySQL (>=5.77) and that's on you how and for what to use this module.
      Thanks:
      Initial point for this fieldtype was jQuery plugin FormBuiled and thanks to Kevin Chappel for this plugin.
      In field type "link" I use javascript part from @marcostoll module and thanks to him for that part.

      Hi guys I'm relatively new to PW and just finished developing a page for a client. I was able to include all necessary functionality using the core fieldtypes but now I it seems that I need to extend them with a custom one. What I need is a simple button, that copies the absolute url (frontend not PW-backend) of the page which is currently edited to the clipboard. As this feature is only needed inside a specific template, I tend to use a custom fieldtype which provides this feature. I've been looking inside the core modules code (eg. FieldtypeCheckbox.module) but I don't really get the structure of it and how its rendered to the admin page. I also didn't find a lot of tutorials covering custom fieldtypes.
      Maybe some of you could give me some tips on how to write a basic custom fieldtype that renders a button which copies the value of
      page->httpUrl() to the clipboard using JS. Thanks!

      Some of you might have followed the development of this module here: https://processwire.com/talk/topic/15524-previewdiscussion-rockdatatables/ . It is the successor of "RockDataTables" and requires RockFinder to get the data for the grid easily and efficiently. It uses the open source part of agGrid for grid rendering.
       
      WHY?
      ProcessWire is awesome for creating all kinds of custom backend applications, but where it is not so awesome in my opinion is when it comes to listing this data. Of course we have the built in page lister and we have ListerPro, but none of that solutions is capable of properly displaying large amounts of data, for example lists of revenues, aggregations, quick and easy sorts by the user, instant filter and those kind of features. RockGrid to the rescue 😉 
       
      Features/Highlights:
      100k+ rows Instant (client side) filter, search, sort (different sort based on data type, eg "lower/greater than" for numbers, "contains" for strings) extendable via plugins (available plugins at the moment: fullscreen, csv export, reload, batch-processing of data, column sum/statistics, row selection) all the agGrid features (cell renderers, cell styling, pagination, column grouping etc) vanilla javascript, backend and frontend support (though not all plugins are working on the frontend yet and I don't plan to support it as long as I don't need it myself)  
      Limitations:
      While there is an option to retrieve data via AJAX the actual processing of the grid (displaying, filtering, sorting) is done on the client side, meaning that you can get into troubles when handling really large datasets of several thousands of rows. agGrid should be one of the most performant grid options in the world (see the official example page with a 100k row example) and does a lot to prevent problems (such as virtual row rendering), but you should always have this limitation in mind as this is a major difference to the available lister options that do not have this limitation.
      Currently it only supports AdminThemeUikit and I don't plan to support any other admin theme.
