Combining two core Inputfield modules in one

Recommended Posts

Hi everyone,

I am fairly new to ProcessWire and am trying to get the hang of creating custom InputFields. Specifically, I am trying to combine two of the core inputfield modules into one custom inputfield. Something that looks like this:

Screen_Shot_2016_06_07_at_3_13_41_PM.png

The purpose of this InputField:

- Used in the Admin area, in the Edit area of a particular page

- In the search, I query for a particular item that exists in PW

- In the results, I can press an add button besides an item that I am interested

- The items that I added is put on the top (the green area), where I can delete them later if I wish

- I can search for new items, get new results, but the green area with the items that I'm interested in previous searches do not go away (unless I navigate away from the page).

So a couple of questions about this:

- Is the top element (the green part) called InputFieldAsnSelect and the bottom part (the search AND the search results) called InputFieldSelector?

- What is a good way to approach this? I'm kind of at a loss on what to do.

    - Do I create a module that extends both InputFieldAsnSelect and InputFieldSelector and try to get them to interact with each other? If so, how? Will this be mostly in JS or in the PHP module? If not, how should I approach this and what should I educate myself on to make this possible?

- My InputField is meant to be able to search all the templates and fields. Would this be possible?

If I get any of the terminology wrong or if a glaring mistake in my understanding of PW is spotted, by all means please point it out.

Thank you!

About the Inputfield names you're mostly correct, but it's ASM not Asn :)

As php doesn't even allow you to extend of of multiple classes you would rather use those module's to render themselves as part of your module. The piece you'll need to add to allow both Inputfields to interact would be mostly JS work, but I'd say you need a good PHP understanding as well as InputfieldSelector is one of the most complex Inputfields we have in pw.

      PrevNextTabs Module
      Github: https://github.com/outflux3/PrevNextTabs
      Processwire helper modules for adding page navigation within the editor.
      Overview
      This is a very simple module that adds Previous and Next links inline with the tabs on the page editor. Hovering over the tab shows the title of the previous or next page (using the admin's built in jqueryUI tooltips.)
      Usage
      This module is typically used during development where you or your editors need to traverse through pages for the purpose of proofing, flagging and/or commenting. Rather than returning to the page tree or lister, they can navigate with these links.
      Warnings
      If you are using PW version 2.6.1 or later, the system will prevent you from leaving the page if you have unsaved edits.
      For earlier versions, to avoid accidentally losing changes made to a page that might occur if a user accidentally clicks on one of these, make sure to have the Form Save Reminder module installed.

      collapsedNoLocked field not showing
      Hi all, ☺️
      I'm a 21 years old 👨‍🦱, danish 🇩🇰, hobby-designer-and-web-stuff-maker and very excited and eager processwire beginner, or "noob" 🐣 if you wish.
      So far I've been fascinated by the very satisfyingly simple and yet powerfull magic ✨ of PW (once you get the hang of it) and the awesome feeling of the strong PW community 🦄🌈☀️❤️! The huge work done by @ryan and all of the other amazing PW people is just so inspiring! I actually really have a hard time understanding why Processwire isn't the most used CMS in the world... or at least just a way more commonly known one!
       
      But now I've encountered a small bump on the road and I'd lovingly appreciate if one of you lovely PW forum members could maybe help me out!
      ❓Problem:
      So I have a problem with the collapsed-constant: https://processwire.com/api/ref/inputfield/#pwapi-methods-collapsed-constants 
      - It's not showing my field when I apply it.
      (I've funnily enough found this old git pull from 2014 which documents the "Locked" state being added as a field -> input -> visibility option: https://github.com/ryancramerdesign/ProcessWire/pull/457 – it also shows the relevant code implementations to the core) 
       
      📝 What I wish to do:
       is to 👀 display some data from a 📦 module (InstagramBasicDisplayApi) in the ⌨️ page editor when editing a page ("About me") using the template (About.php) - So the only possible way to do that as far as for what I've been able to come up with with my restricted PW (end eh.. php) –knowledge was to add a custom field type to the (About.php) template...
      I've set up a custom field using https://modules.processwire.com/modules/mystique/ :
      site/modules/configs/Mystique.php:
      <?php namespace ProcessWire; $modules = wire("modules"); $instagram = $modules->get("InstagramBasicDisplayApi"); $data = array('username'=>''); $account = $instagram->getUserAccount($data["username"]); $username = isset($account["username"]) ? $account["username"] : ""; $at_instausername = "@" . $username; /** * Resource : Instagram account */ return [ 'title' => __('Instagram account'), 'fields' => [ 'window_title' => [ 'label' => __(' '), 'type' => Mystique::TEXT, // or InputfieldText 'useLanguages' => true, 'collapsed' => '0', 'placeholder' => __($at_instausername), ] ] ]; - Basically:
      I'm getting the instagram-username, pulling it from the module "InstagramBasicDisplayApi",  And then I'm using it as the 'placeholder' value for the field, resulting in this:  - Which is actually what I want... almost...
      – The thing is, I would like it to be locked, so that it's not possible to overwrite the 'placeholder' value, but so that the inputfield actually does not take any input but just informatively displays the data...
      so what I do is that I just change 'collapsed' to '7' = 'collapsedNoLocked':
      'collapsed' => '7', , right, and that would be it?
      But unfortunately no...
      When I do I get this:
       
       - I can't figure out why? I'd supposed that the 'placeholder' value would just show, but non-editable?
      A "workaround" is to just set it to back to 0, then manually type in "@sasha_lindegaard" and then press save, and then set it to 7, and I have what I want:

      - But that's not really what I wish, as it displays the data (the instagram username) statically (from what I've typed into the field and have saved) and not dynamically (from the instagram module database) as wished for...
      – also, it's still collapsable? Why so?... 🤔
       
      Any ideas for how I might get my "INSTAGRAM" field to display the username from the instagram module's database dynamically, not as editable placeholder text in a editable/open input field but just as non-editable/locked text?
      I hope that I've made my problem clear enough but if I've failed to provide enough info please don't hesitate to request for more! 🙂 
      Thanks a thousand times in advance!
      All the best,
      Jonatan R.

      Updating from prior versions:
       
      Updating from Croppable Image 3 with versions prior to 1.1.7, please do this as a one time step:
      In the PW Admin, go to side -> modules -> new, use "install via ClassName" and use CroppableImage3 for the Module Class Name. This will update your existing CroppableImage3 module sub directory, even if it is called a new install. After that, the module will be recogniced by the PW updater module, what makes it a lot easier on further updates.
