Plugin that automatically changes the resource type (class_key) depending on the parent

Hi all,

On several projects, I use a plugin I got from here which automatically sets the desired template on a resource depending on its parent.

Which is

<?php
if ($_GET['a'] = 47) {
$parentID = (int) $_REQUEST['parent'];
 if ($parent = $modx->getObject('modResource', $parentID)){
 
 
 if ($parentID == 4 || $parentID == 3) {
 $produitTpl = 1; 
 $_GET['template'] = $produitTpl ;
 }


}
}

and works fine.

Wielding the sword like if I was blind, I tried to... adjust... this plugin and make it change the Resource Type ( [[*class_key]] ), but uhh.. is this about... xPDO, right ? Well, I tried, I fiddled, I went there :

<?php
if ($_GET['a'] = 47) {
$parentID = (int) $_REQUEST['parent'];
 if ($parent = $modx->getObject('modResource', $parentID)){
 
 
 
 if ($parentID == 10 || $parentID == 11) {
 $classKeyGallery = mgResource;
 $_GET['classKey'] = $classKeyGallery ;
 }


}

I checked OnHandleRequest. Only.

Of course, it doesn't work. Now can you please tell me if it's just a fine-tuning I can expect, or is it just a mess ? Thank you

wait, it was obvious for me but it's not for you, reader :

I want to do this because I installed Mark's MoreGallery - which allows you to change a resource's type to Gallery (so you can upload a whole gallery directly into the resource).

MoreGallery outputs

mgResource

as the [[*class_key]]

Would it work to do this in a plugin attached to OnDocFormSave?

$parentId = $resource->get('parent');
if ($parentId == 10 || $parentId == 11) {
    $resource->set('class_key', 'mgResource');
    $resource->save();
}
return '';

Might want to add a check for "new" or "update" too, just to cut down on unnecessary processing. Of course, that would be presuming that any child resources being updated are already using the correct class_key.

Thanks both - actually Bob's suggestion won't work yet :

Fatal error: Call to a member function get() on a non-object in /.../core/cache/includes/elements/modplugin/10.include.cache.php on line 3

It would be great if, as on the template-plugin, the modification gets made as soon as the resource is created... is that what you meant Susan ? which System Events are concerned then ?

(This is about my client ; that way he wouldn't have to click on the Config tab, click on Content Type, get lost, click on resource type, find Gallery, click, wait for reload... then proceed.) But wait, I wish I would not seem demanding !

oops, detail :

I forgot to uncheck OnHandleRequest in the plugin Bob suggested. Now it's done :

There's no more fatal error displayed, there's no error at all, but it just doesn't work.

Do you have OnDocFormSave checked?

Actually, you might be better off using OnBeforeDocFormSave. According to the docs, you can do something like

if ($resource->get('parent') == 123) {
        $resource->set('template') = 4;
}

So you should be able to use

if ($resource->get('parent') == 123) {
        $resource->set('class_key', 'mgResource');
}

For the OnDocFormSave plugin,

$parentId = $resource->get('parent');
if ($parent == 10 || $parent == 11) {
    $resource->set('class_key', 'mgResource');
    $resource->save();
}

Shouldn't that be

$parentId = $resource->get('parent');
if ($parentId == 10 || $parentId == 11) {
    $resource->set('class_key', 'mgResource');
    $resource->save();
}

Both of your plugins work, Susan, thank you.

The user needs to enter a title at least then hit Save, and that's okay.

OnBeforeDocSave is then more convenient : you experience only one page reload after hitting Save, instead of two with OnDocFormSave.
