CB Gallery file upload validation

Hi Kyle

I use CB Gallery to allow upload of images and files.

It works fine but I would like to add a validation step for some files llke CSV which are sometimes badly formatted by users. In this case, our AI fails in integrating them in our neuralDB

So I was thinking at a validation step before upload.

Is there a trigger that I could use with CB Gallery for this ?

The kind of code I was thinking about is 

I guess that a code autoaction could do it but do not really know how to set it ?


On a second point :
Is there a trigger to change the display of the footer in a CB Gallery thumbnail item display ?
I'd like to make a DB check to see if there exists our AI source_id for the gallery_item_id displayed and display a green or red icon accordingly


Thanks for your help

So I was thinking at a validation step before upload.

Custom validation can be done on the gallery_onBeforeCreateGalleryItem trigger. Its variables are as follows.



var1 being the gallery object of the gallery being uploaded to
var2 being the source object for the gallery (profile object, groupjive group object, etc..)
var3 being the new gallery media object

You'd have to check the files input data for the uploaded file and apply whatever parsing you need from there. The below should work and assumes you're using a Code action with PHP.



That should give you an array of the file data. You can then open it from php tmp and do whatever validation you need to do. If you need to throw an error you can do it with the following.

Yes, there's a trigger for that as well. gallery_onDisplayItem is fired during container displays and any content returned during that trigger is inserted into the footer. Its variables are as follows.



var1 being the gallery media object
var2 being an array of drop menu items
var3 being the gallery object for that media

Thanks a lot that will do

Last question : I use gallery_onAfterCreateItem and gallery_onAfterUpdateItem in a code autoaction with a PHP code sending the item to our AI DB, the code returns a json like :
return $output = json_encode( [
'success' => 'true',
'sourceID' => 'registered',
'error' => 'none',
] );

Is it possible to display something in the ajax window used to save the item ?
I mean can I add something to the validation message when the user saves the item.

As it's on ItemTable I cannot find the idea

Only way to do that would be to act on gallery_onBeforeItemEditMini and return whatever message you're wanting. That trigger is used for the mini edit display during the upload process that's shown after an upload completes (where you can change folder, title, description, etc..). Its variables are as follows.

var1 being the gallery media object
var2 being the http request input object
var3 being the viewing user object
var4 being the gallery object for that media

Anything returned during that trigger will show at the top while gallery_onAfterItemEditMini (same variables as above) would show at the bottom.

I assume that's where you mean to add this? Otherwise you'll need to be more specific as to what view you want this displayed on.

Yes I think that gallery_onAfterItemEditMini should be the one to use as it's the area where the save message is displayed.

However I cannot see how to link my two autoactions.

The first one uses gallery_onAfterCreateItem and gallery_onAfterUpdateItem to trigger the sending of the file to the AI DB. This one works fine and the PHP code returns the json stated above.

But how can I use this return (or any other else) to change the display of the save message with gallery_onAfterItemEditMini ?

The media object is passed by reference. So you can add new properties to it using property getter/setter functions. Example as follows.

Set Get
The output of the mini edit is not a redirect so you can pass data through to it using this method and then use that data in your display.
