Drag and Drop ignores allowedContentTypes and deniedContentTypes

[monosize]

If dragging an element into a flux:grid which has a defined allowedContentTypes or deniedContentTypes, the defintions are ignored and the element is added to the column.

Only a insert over the element wizard checks the valid content type!

<flux:grid.column name="elements">
    <flux:form.variable name="allowedContentTypes" value="fluidcontent_content"/>
    <flux:form.variable name="Fluidcontent" value="{allowedContentTypes: 'Vendor.Extension:ContentElement.html'}"/>
</flux:grid.column>

Idea

• Insert a missing check in flux for a moved element if it is allowed to move into the column.
• Extend dropzones with data attributes data-allowed-content-types="fluidcontent_content"or data-denied-content-types="fluidcontent_content" and if needed with data-allowed-fluidcontent="Vendor.Extension:ContentElement.html"
• Extend all dragable elements with data attributes data-content-type="fluidcontent_content" data-fluidcontent-type="Vendor.Extension:ContentElement.html"
• Extend DragDrop.js - if Drag Start find all dropzones which not allowed to drop the element and hide them. After Drop reset the dropzones.
• Changing the DragDrop.js would be easier with the new DragDrop.js form the TYPO3 8 branch

Hi @monosize
i saw this related ticket on forge: https://forge.typo3.org/issues/7459

Do you have any idea how to fix this issue, at least temporarily

[ogrosko]

I'm trying to fix this issue by following hook

For now it works for content inserted to page columns. You will get error and element is not moved/copied to denied page colPos

But I have no idea how to fix it for Flux grid. When I use any hook colPos of moved element is always different e.g.:

array(1) {
  ["tt_content"]=>
  array(1) {
    [25]=>
    array(2) {
      ["colPos"]=>
      string(5) "20450"
      ["sys_language_uid"]=>
      string(1) "0"
    }
  }
}

colPos is still different for each page load and grid column, but in database it is always colPos = 18181

Place where I stuck is here. At this place I would need to know tx_flux_parent and tx_flux_column fields value of modified tt_content record.

Any ideas where is set colPos for element placed in gridelement? Or What kind of hook would I need?
Thx

Check this prototyped plugin

UPDATE: drag&drop, copy/move should work now

[ogrosko]

I've noticed that column variable allowed/disallowedContentTypes is inherited to subpages.
Eg.
I have Default.html page template with defined <flux:form.variable name="allowedContentTypes" value="textpic"/>
And some subpage with Subpage.html page template with definded <flux:form.variable name="allowedContentTypes" value="list"/>

In Subpage.html content wizard both elements are available textpic and list. I would expect only list element available in Subpage.html. Is it possible to disable this inheritance?
