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.)

Hi 

after I changed a domain to ssl, HannaCode throws on error on each saving. Anyone any idea on how this could be solved?

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. ;)

Just in case you don't know, there is a setting under your forum profile for automatically following topics that you post to.

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.

      MediaLibrary
      Update: MediaLibrary can now be found in the official module list.
      Out of necessity, I've started to implement a simple media library module.
      The basic mechanism is that it adds a MediaLibrary template with file and image fields. Pages of this type can be added anywhere in the page tree.
      The link and image pickers in CKEditor are extended to allow quick selection of library pages from dropdowns. In the link picker this happens in the MediaLibrary tab, where you can also see a preview of the selected image. In the image picker, simply select a library from the dropdown at the top, everything else is handled by standard functionality.
      I've put the code onto github. This module is compatible with ProcessWire 3.
      Steps to usage:
      Download the module's zip from github (switch to the pw3 branche beforehand if you want to test on PW 3.x) and unpack it into site/modules Click "Modules" -> "Refresh" in the admin Click "Install" for MediaLibrary For testing, create a page with the MediaLibrary template under home (give it an expressive title like 'Global Media') and add some images and files Edit a differnt page with a CKEditor field and add a link and an image to see the MediaLibrary features in action (see the screencap for details) Optionally, go into the module settings for MediaLibrary Note: this module is far from being as elaborate as Kongondo's Media Manager (and doesn't plan to be). If you need a feature-rich solution for integrated media management, give it a look.
      Feel free to change the settings for MediaFiles and MediaImages fields, just keep the type as multiple.
      There are some not-so-pretty hacks for creating and inserting the correct markup, which could probably be changed to use standard input fields, though I'm a bit at a loss right now how to get it to work. I've also still got to take a look at error handling before I can call it fit for production. All feedback and pointers are appreciated (that's also why I post this in the development section).

      Edit 09.03.2016 / version 0.0.4: there's now also a "Media" admin page with a shortcut to quickly add a new library.

      Edit 01.05.2016:
      Version 0.0.8:
      - The module now supports nested media libraries (all descendants of eligible media libraries are also selectable in link/image picker).
      - There's a MediaLibrary::getPageMediaLibraries method you can hook after to modify the array of available libraries.
      - You can switch between (default) select dropdowns or radio boxes in the module configuration of MediaLIbrary to choose libraries.
      Edit 10.10.2018:
      Version 0.1.3:
      - Dropped compatibility for ProcessWire legacy versions by adding namespaces
      - Allow deletion of libraries from the Media overview admin page
      - Added an option to hide media libraries from the page tree (optionally also for superusers)

      This module corrects a few things that I find awkward about the "Add New Template" workflow in the PW admin. I opened a wishlist topic a while back because it would good to resolve some of these things in the core, but this module is a stopgap for now.
      Originally I was going to share these as a few standalone hooks, but decided to bundle them together in a configurable module instead.
      Add Template Enhancements
      A module for ProcessWire CMS/CMF. Adds some efficiency enhancements when adding or cloning templates via admin.

      Features
      Derive label from name when new template added: if you like to give each of your templates a label then this feature can save some time. The label can be added automatically when templates are added in admin, in admin/API, or not at all. There are options for underscore/hyphen replacement and capitalisation of the label. Edit template after add: when adding only a single template, the template is automatically opened for editing after it is added. Copy field contexts when cloning: this copies the field contexts (a.k.a. overrides such as column width, label and description) from the source template to the new template when using the "Duplicate/clone this template?" feature on the Advanced tab. Copy field contexts when duplicating fields: this copies the field contexts if you select the "Duplicate fields used by another template" option when adding a new template. Usage
      Install the Add Template Enhancements module.
      Configure the module settings according to what suits you.

      As I mentioned in this issue, I've create a new textformatter for ParsedownExtraPlugin, which adds some oomph to your markdown.
      Repo: Parsedown Extra Plugin
      Unlike the built-in textformatter for Parsedown and Parsedown Extra, this should be used when you want to use Extra with additional configuration/customisation.
      Some examples:
      ### Test {.heading} - A [external link](https://google.com/){.google} with `google` as a class that opens in a new tab if the config property is set. - [Another link](/page){target=_blank} that opens in a new tab even though it isn't external. ```html .html <p>Test</p> ``` There's some config options available to you, such as setting attributes on all/external images and links, setting table and table-cell alignment classes, adjusting footnote classes and IDs, adding <code> attributes to their parent <pre> elements, and changing the <code> class if your syntax highlighter does not use language-*.
      I was thinking about adding the ability to make links open in a new tab by appending a plus to the link syntax, but only external links should be opening in a new tab anyway. Further, this would add extra, unnecessary processing time.
      Please let me know if you bump into any problems. ☺️

      TextformatterTypographer (0.4.0 Beta)
      A ProcessWire wrapper for the awesome PHP Typography class, originally authored by KINGdesk LLC and enhanced by Peter Putzer in wp-Typography. Like Smartypants, it supercharges text fields with enhanced typography and typesetting, such as smart quotations, hyphenation in 59 languages, ellipses, copyright-, trade-, and service-marks, math symbols, and more.
      Learn more on my blog
      It's based on the PHP-Typography library found over at wp-Typography, which is more frequently updated and feature rich that its original by KINGdesk LLC.
      The module itself is fully configurable. I haven't done extensive testing, but there is nothing complex about this, and so I only envisage a typographical bug here and there, if any.
      Please do test it out and let me know what you think.
      Also note that I have indicated support for PW 2.8, but I haven't tested there as yet. This was built on PW 3.0.42/62.

      Jumplinks for ProcessWire
      Release: 1.5.50
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy!
