Page Image Manipulator 2

Recommended Posts

Hi, I have uploaded a new version to Github that fully supports PW 2.6+ with its new naming scheme.

The package now ships with two Pim versions, the older one, called Pim, that can be used until PW 2.5 stable, and the new one, Pim2 that should be used with PW 2.6+

So, if you start a new site with PW 2.6+, simply install Pim2 only!

If you have upgraded PW to 2.6 on an existing site with lots of image variations, you

  1. should install Pim2 additionally to the older one, (do not uninstall it yet!)
  2. then you should start to change your API calls in your templates like the following explanation


here is a code line from the older Pim:

$image = $image->pimLoad($prefix)->watermarkText($txt, 75)->setQuality(80)->pimSave();


To start with smooth change from Pim to Pim2, you can change it to this:

// use the old Pim to remove the PimVariations with old naming scheme:

// in the copied original code line, only change pimLoad to pim2Load, note the number 2 ! in the new start method !
$image = $image->pim2Load($prefix)->watermarkText($txt, 75)->setQuality(80)->pimSave();


This way you have some control on which parts the new creation may take effect, e.g. on a small site you can change all API calls at once and drop caches if exists. On bigger sites you may start at one template / page first, and add more changes later.


Regardless of this, you can safely let the call to the older removePimVariations() method stay in your code for a while, as they do not interact with the newer one. After a while, when you do not see any of those old filenames in your assets/files folders, you can remove those lines from your code and also uninstall the older Pim.

All other methods than pimLoad / pim2Load are completly identical and can be seen here in the API

Hello! How is going?
I am confused how to update pim2 from PW (or really anywhere). Currently I got both pim1 and pim2 installed, but only pim1 is shown in ProcessWireUpgrade with the version 2.1 while pim2 is 2.7. Is there a proper way to handle this?

There are no plans to update Pim2. And if it will be updated, the version number from Pim1 will be bumped up, so that it shows up in the update modules list. (Pim2 is handled as submodule of Pim, Pim1)

To be correct:

Install pim, what installs pim1, go to modules / site, install pim2 and use pim2load().

It needs a rewrite someday for recent PW versions (2.8+ & 3.0+) :)

Hi @horst, I tried out this module today and it's nice, thanks. :)

But the installation process and the PIM1/PIM2 thing was clear as mud to me - I got it worked out in the end but I don't understand why the module is set up that way.

I get the need for different module versions according to which PW version you are running, but couldn't PIM1 and PIM2 be separate modules be in separate GitHub repos and you just install the one you want? Or better - could there just be a single module that checks the PW version number and uses the right code for that version? That way pimLoad() and pimSave() wouldn't have to be renamed and choosing/installing/using the module would be simpler for the user.

@Robin S it was due to an needed upgrade from Pim1 to Pim2 because of changes in the naming conventions for images in PW > 2.6.?.

At this time Pim1 already was installed and used in many sites. When people upgraded their PW version in those sites, they could not / cannot simply change Pim1 with Pim2. There was a manually action in changing API calls in template files needed. This was / is the reason for this weird behave.

For the simply case of first install of the module, I can use a PW version detection of course, but that wasn't the problem. The problem was / is, that in prior PW versions with use of Pim1:

  • i must used the Pim1 as first / only module, to get the people informed about update changes via upgrade-module(s)
  • must ommit an automated change from old naming convention to the new one, because sites possibly would break down if I would raise a need to recreate every image (!)

So, yes, I was and I'am very unhappy with this situation. If someone has a better solution, please tell me.


BTW, with the CroppableImage3 I run into something similar:

Croppable3 isn't recognized by the widely used upgrade-module from Ryan, so people don't get informed about updates of it. I believe, many sites are running a version prior to 0.9.17. Everytime someone updates an older PW version site to a newer version, they run into a bug that was already fixed a year ago in version 0.9.17. People than always report that they just upgraded from x to PW > 3.0.31* (or similar), and the module now wouldn't work anymore. :( But it is already fixed. They all need to do a manual update, but how can I inform them? The updater should do so, but doesn't do. :(

@horst, I can see how that upgrade would be difficult to do gracefully. Will post back if I have any ideas.

Regarding CroppableImage3 and the ProcessWireUpgrade module: I think the reason why the upgrades module doesn't see available updates for CI3 is due to the module class name that is showing in the modules directory. The class name shown is "CroppableImage3" but I'm not sure where that comes from because it isn't actually a class name that is used in the modules (correct me if I'm wrong). Did you enter that manually? Or maybe it comes from the name of the GitHub repo?

When the upgrades module queries the modules directory it is looking for the classnames...

  • FieldtypeCroppableImage3
  • InputfieldCroppableImage3
  • ProcessCroppableImage3

...but it doesn't find a match for any of these, therefore they are left out of the table of upgradable modules.

Maybe it would be best to follow the example of several of the other fieldtype modules, where the primary name of the module would be FieldtypeCroppableImage3 even though it auto-installs two other modules.

The reason it wasn't detected was, that no module was in the root directory of the module, but all each of the three modules resides in its own subdirectory.

      Repeater Images
      Adds options to modify Repeater fields to make them convenient for "page-per-image" usage. Using a page-per-image approach allows for additional fields to be associated with each image, to record things such as photographer, date, license, links, etc.
      When Repeater Images is enabled for a Repeater field the module changes the appearance of the Repeater inputfield to be similar (but not identical) to an Images field. The collapsed view shows a thumbnail for each Repeater item, and items can be expanded for field editing.

      Install the Repeater Images module.
      Create an image field to use in the Repeater field. Recommended settings for the image field are "Maximum files allowed" set to 1 and "Formatted value" set to "Single item (null if empty)". Create a Repeater field. Add the image field to the Repeater. If you want additional fields in the Repeater create and add these also. Repeater Images configuration
      Tick the "Activate Repeater Images for this Repeater field" checkbox. In the "Image field within Repeater" dropdown select the single image field. You must save the Repeater field settings to see any newly added Image fields in the dropdown. Adjust the image thumbnail height if you want (unlike the core Images field there is no slider to change thumbnail height within Page Edit). Note: the depth option for Repeater fields is not compatible with the Repeater Images module.
      Image uploads feature
      There is a checkbox to activate image uploads. This feature allows users to quickly and easily add images to the Repeater Images field by uploading them to an adjacent "upload" field.
      To use this feature you must add the image field selected in the Repeater Images config to the template of the page containing the Repeater Images field - immediately above or below the Repeater Images field would be a good position.
      It's recommended to set the label for this field in template context to "Upload images" or similar, and set the visibility of the field to "Closed" so that it takes up less room when it's not being used. Note that when you drag images to a closed Images field it will automatically open. You don't need to worry about the "Maximum files allowed" setting because the Repeater Images module overrides this for the upload field.
      New Repeater items will be created from the images uploaded to the upload field when the page is saved. The user can add descriptions and tags to the images while they are still in the upload field and these will be retained in the Repeater items. Images are automatically deleted from the upload field when the page is saved.
      The "Use accordion mode?" option in the Repeater field settings is useful for keeping the inputfield compact, with only one image item open for editing at a time. The "Repeater item labels" setting determines what is shown in the thumbnail overlay on hover. Example for an image field named "image": {image.basename} ({image.width}x{image.height})

      Hello There Guys.

      I am in the process of getting into making my first modules for PW and i had a question for you PHP and PW gurus in here.

      I was wondering how i could use an external library, lets say TwitterOAuth in my PW module.
      Link to library

      Would the code below be correct or how would i go about this:
      <?PHP namespace ProcessWire; /* load the TwitterOAuth library from my Module folder */ require "twitteroauth/autoload.php"; use Abraham\TwitterOAuth\TwitterOAuth; class EyeTwitter extends WireData,TwitterOAuth implements Module { /* vars */ protected $twConnection; /* extend parent TwitterOAuth contructor $connection = new TwitterOAuth(CONSUMER_KEY, CONSUMER_SECRET, $access_token, $access_token_secret); */ public function myTwitterConnection ($consumer_key, $consumer_secret, $access_token, $access_token_secret) { /* save the connection for use later */ $this->twConnection = TwitterOAuth::__construct($consumer_key, $consumer_secret, $access_token, $access_token_secret); } } ?> Am i on the right trail here or i am barking up the wrong tree?
      I don´t need a complete solution, i just wonder if i am including the external library the right way.
      If not, then give me a few hint´s and i will figure it out.

      Thanks a bunch.

      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version (has been tested up to v3.3), add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "http://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
      PW module directory: http://modules.processwire.com/modules/auto-fb-post/ Github: https://github.com/kastrind/AutoFbPost   Note: Facebook SDK for PHP is utilized.

      FieldtypeRuntimeMarkup and InputfieldRuntimeMarkup
      Modules Directory: http://modules.processwire.com/modules/fieldtype-runtime-markup/
      GitHub: https://github.com/kongondo/FieldtypeRuntimeMarkup
      As of 11 May 2019 ProcessWire versions earlier than 3.x are not supported
      This module allows for custom markup to be dynamically (PHP) generated and output within a page's edit screen (in Admin).
      The value for the fieldtype is generated at runtime. No data is saved in the database. The accompanying InputfieldRuntimeMarkup is only used to render/display the markup in the page edit screen.
      The field's value is accessible from the ProcessWire API in the frontend like any other field, i.e. it has access to $page and $pages.
      The module was commissioned/sponsored by @Valan. Although there's certainly other ways to achieve what this module does, it offers a dynamic and flexible alternative to generating your own markup in a page's edit screen whilst also allowing access to that markup in the frontend. Thanks Valan!
      Although access to ProcessWire's Fields' admin pages is only available to Superusers, this Fieldtype will evaluate and run the custom PHP Code entered and saved in the field's settings (Details tab). Utmost care should therefore be taken in making sure your code does not perform any CRUD operations!! (unless of course that's intentional) The value for this fieldtype is generated at runtime and thus no data is stored in the database. This means that you cannot directly query a RuntimeMarkup field from $pages->find(). Usage and API
      Enter your custom PHP snippet in the Details tab of your field (it is RECOMMENDED though that you use wireRenderFile() instead. See example below). Your code can be as simple or as complicated as you want as long as in the end you return a value that is not an array or an object or anything other than a string/integer.
      FieldtypeRuntimeMarkup has access to $page (the current page being edited/viewed) and $pages. 
      A very simple example.
      return 'Hello'; Simple example.
      return $page->title; Simple example with markup.
      return '<h2>' . $page->title . '</h2>'; Another simple example with markup.
      $out = '<h1>hello '; $out .= $page->title; $out .= '</h1>'; return $out; A more advanced example.
      $p = $pages->get('/about-us/')->child('sort=random'); return '<p>' . $p->title . '</p>'; An even more complex example.
      $str =''; if($page->name == 'about-us') { $p = $page->children->last(); $str = "<h2><a href='{$p->url}'>{$p->title}</a></h2>"; } else { $str = "<h2><a href='{$page->url}'>{$page->title}</a></h2>"; } return $str; Rather than type your code directly in the Details tab of the field, it is highly recommended that you placed all your code in an external file and call that file using the core wireRenderFile() method. Taking this approach means you will be able to edit your code in your favourite text editor. It also means you will be able to type more text without having to scroll. Editing the file is also easier than editing the field. To use this approach, simply do:
      return wireRenderFile('name-of-file');// file will be in /site/templates/ If using ProcessWire 3.x, you will need to use namespace as follows:
      return ProcessWire\wireRenderFile('name-of-file'); How to access the value of RuntimeMarkup in the frontend (our field is called 'runtime_markup')
      Access the field on the current page (just like any other field)
      echo $page->runtime_markup; Access the field on another page
      echo $pages->get('/about-us/')->runtime_markup; Screenshots
