Module
Pagetree Add New Child Reverse (on Top)

Pagetree Add New Child Reverse

New Pages in Descending Sortorder (newest first) while sortmode can be "Manual Drag-n-Drop"
 
When a site display an overview of the latest posts, news, image-albums, etc. the newest entries should be on top of the list. We can achieve that by using an automated setting for the sortfield e.g. when the page was created = "-created".
 
But this way we are not able to manually move a single page in the tree.
 
This module enables us to do exactly that. It works with manually created pages, with pages created via the API, also when bootstrapped by importer scripts.
 
 
 
Pagetree "Newsitems" with 3 newsitems sorted in descending order.

New created item 4 is added to the top.

To change the order click item 3 and drag it to the top and drop it.

How to use it

Download the module into your site/modules/ directory and install it.
 
In the config page you find a single textarea field. Here you can enter the templatename or page-ID of the page which children should get reverse added, - optionally followed by a comma and the child-templatename if you need a more precise selector.
 
You can add as many parents as you like, but only one on each line and in this format:
TEMPLATE-NAME or PAGE-ID[,CHILDTEMPLATE-NAME].
 
A few examples:

newsitems
posts,post
1042
1033,album

 
You want set your template(s) sortfield(s) to 'Manual drag-n-drop' if not have done already.

 
ATTENTION
 
You need to setup the TreeParent and the module config when there are no children in it! Otherwise it will not work!
 
Also disabling the module once you have added children and then add one new page to it will mess up all!
(You may think about to install the module as permanent in critical situations.?! see below ->)

If you need to install it in a site for an already existing branch, you can do it this way:

  1. move / rename your existing branch
  2. create a new (empty) branch with the original name
  3. move your childpages into the new branch
  4. remove the renamed (and now empty) old branch

 
 
DOWNLOAD   -  Version 1.0.2

 
 
Want to make it bulletproof?
 
If you are concerned that the module settings could be dropped by other users or that the module itself could be uninstalled by accident, you may edit the module file directly:

This way the permanent settings couldn't be dropped by accident. To change it you first need to edit the modules file again.

Example:

You have two settings in the inputfield of the modules config, without permanent setting:

parenttemplate1,childtemplate1
parenttemplate2,childtemplate2

Now you want to have the the first setting become bulletproof permanent:

a) you enable the setting in the getModuleInfo, (uncomment setting for permanent)

b) you write your permanent settings under the constant permanentValue

const permanentValue = "parenttemplate1,childtemplate1";

After both steps, the module cannot get uninstalled anymore (Step a), and the first setting cannot get deleted anymore (Step b), as it is recreated with every call of the configscreen. (See first code line of method getModuleConfigInputfields)

If you want to keep both definitions permanent, write them separated with a newline character "\n" :

const permanentValue = "parenttemplate1,childtemplate1\nparenttemplate2,childtemplate2";

Wow, I can't wrap my mind around this. How is this possible without heavy overhead. Great work Horst, thank You !

Sneakpeeked at the code... clever :-)

This does look great horst.

I think it is something I am going to have to be aware of though as my page tree migrator module gets closer to release. I can see it being an issue if migrating pages from a site that has this installed, or to one that has it installed if the other doesn't. Not sure how to handle that, but we'll see :)

Just curious - did you test the idea of negative number indexing? Might be opening another can of worms though!

It doesn't work with negative numbers. They get corrected to 0 (zero) at some other points in PW, not only at Pages::setupNew() :(

I have template pr-index, children (template pr-item) are reverse sorted by pubdate (Datetime field in pr-item), not reverse sorted by created date. Is it possible to have manual drag-n-drop in this situation?

Hey, love the plugin but this would really benefit from using the Selector inputfield as a selector instead of the textarea. :)

      First a note about my other modules...
      I have three existing modules that are similar in that they allow restrictions to be placed on repeating inputfields: Limit Repeater, Limit PageTable, Limit Table
      Restrict Repeater Matrix takes a different approach to the module configuration from those other modules. The module settings for Restrict Repeater Matrix are applied in the field settings rather in a module config screen. I think this new approach is better, but it means that it isn't practical to create different settings for different roles via the admin interface. Instead the module has a hookable method, allowing roles to be targeted and other advanced usages to be achieved via a hook. The result is that the module is more flexible.
      I intend to transition my other modules to the same approach over the coming weeks, but because this will result in breaking changes I will be releasing the updated modules under new names ("Restrict Repeater", etc) to avoid users upgrading via the Upgrades module without full awareness of the changes. The old modules will be marked as deprecated.
       
      Restrict Repeater Matrix
      A module for ProcessWire CMS/CMF. Allows restrictions and limits to be placed on Repeater Matrix fields.
      For any matrix type in a Repeater Matrix field you have the option to:
      Prevent drag-sorting of items Prevent cloning of items Prevent toggling of the published state of items Prevent trashing of items Limit the number of items that may be added to the inputfield Please note that restrictions and limits are applied with CSS/JS so should not be considered tamper-proof.
      Usage
      Install the Restrict Repeater Matrix module.
      For each matrix type created in the Repeater Matrix field settings, a "Restrictions" fieldset is added at the bottom of the matrix type settings:

      For newly added matrix types, the settings must be saved first in order for the Restrictions fieldset to appear. Set restrictions for each matrix type as needed. A limit of zero means that no items of that matrix type may be added to the inputfield.
      Setting restrictions via a hook
      Besides setting restrictions in the field settings, you can also apply or modify restrictions by hooking RestrictRepeaterMatrix::checkRestrictions. This allows for more focused restrictions, for example, applying restrictions depending on the template of the page being edited or depending on the role of the user.
      The checkRestrictions() method receives the following arguments:
      $field This Repeater Matrix field $inputfield This Repeater Matrix inputfield $matrix_types An array of matrix types for this field. Each key is the matrix type name and the value is the matrix type integer. $page The page that is open in ProcessPageEdit The method returns a multi-dimensional array of matrix types and restrictions for each of those types. An example of a returned array:

      Example hooks
      Prevent the matrix type "images_block" from being added to "my_matrix_field" in a page with the "basic-page" template:
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $page = $event->arguments('page'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && $page->template->name === 'basic-page') { $type_restrictions['images_block']['limit'] = 0; } $event->return = $type_restrictions; });  
      Prevent non-superusers from trashing any Repeater Matrix items in "my_matrix_field":
      $wire->addHookAfter('RestrictRepeaterMatrix::checkRestrictions', function(HookEvent $event) { $field = $event->arguments('field'); $type_restrictions = $event->return; if($field->name === 'my_matrix_field' && !$this->user->isSuperuser()) { foreach($type_restrictions as $key => $value) { $type_restrictions[$key]['notrash'] = true; } } $event->return = $type_restrictions; });

      Hi,
      just stumbled over a little module that i built for my last project. it helped me to test performance of my rockdatatables module to generate 3000 random json datasets and i want to share it with you. maybe it saves some time for someone.
      https://gitlab.com/baumrock/RockDummyData/
      easy example:
      $rdd = $modules->get('RockDummyData'); for($i=0; $i<15; $i++) { // this has to be inside the for-loop to always get a new dummy $dummy = $rdd->getDummy(); echo date("d.m.Y H:i:s", $dummy->timestamp) . "<br>"; } more advanced:
      $json = new stdClass(); $json->data = array(); $rdd = $modules->get('RockDummyData'); for($i=0; $i<3000; $i++) { // this has to be inside the for-loop to always get a new dummy $dummy = $rdd->getDummy(); $obj = new stdClass(); $obj->name = $dummy->forename . ' ' . $dummy->surname; $obj->position = $dummy->job; $obj->office = $dummy->city; $obj->color = $dummy->color; $obj->start_date = new stdClass(); $obj->start_date->display = date('d.m.Y',$dummy->timestamp); $obj->start_date->sort = $dummy->timestamp; $obj->salary = rand(0,10000); $json->data[] = $obj; } echo json_encode($json); you have to store your random datasets on your own into the /data folder. there are several services for creating all kinds of random data on the web - if you know one service that allows sharing those datasets let me know and i can include common needed data into the module

      Hello!
      I need your assistance please. I purchased the module FormBuilder. Unfortunately, the module discontinued delivering customer submissions to e-mail box specified in the module settings. Direct mailing to the e-mail box works OK. The module settings stays the same and are correct, like "Send e-mail to administrator(s) is checked. The last version of FormBuilder 3.0 has been installed. Please advise how to resolve the issue becase I cannot get orders from customers anymore (((

      As described in this post (https://processwire.com/talk/topic/8551-custom-urls-for-pages/?p=82742) the option 'Name Format Children' under the tab 'Family' in template settings doesn't work properly and also not as expected. I had a look inside the code and made some changes which are working properly, which offers much more options, more consistency and less code too.

      The result is the following. You have 3 Options for generating name and title, which could be combined in endless variations.
      Name is always derived from title, same like creating pages manually.
      type date: if function detects # character anywhere in the string, conversion will be: deletion of # and string will be used as format parameter for PHP date() function type field: if string is a fieldname of the parent page the value of this field will be used type string: if string doesn't fit to the 2 preceeding it will be taken as it is All parts (separated by comma) will be composed in the order of setting. You can use unlimited numbers of parts

      FieldtypeRuntimeMarkup and InputfieldRuntimeMarkup
       
      Modules Directory: http://modules.processwire.com/modules/fieldtype-runtime-markup/
      GitHub: https://github.com/kongondo/FieldtypeRuntimeMarkup
       
      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!
       
      Warning/Consideration
      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
       
      Backend
      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
