Canceling saving of an item via onBeforeSaveField function

I was an example.

Imagine I have a youtube link :

A user just fill in the link, and my script extract the id : lHTAV9H8yK4
the title, and the image (just the link).
I would like to store all these data in different fields (video_id, image, title, link)

its simply create a texte field allow plugin to insert video example jw video
and use {youtube}prefix and {/youtube} suffix
extensions.joomla.org/extensions ... allery/812
regards

It would be too simple

The video could be a youtube video, or dailymotion, or ...

I have to execute a script in order to get all the video's information and fill other fields (extract the title to name the article, ...)

I will use :

with a field own-made.

But I would like to know if it is possible to fill a field through another ?
Maybe in the form ?

Check this FAQ article, but note it is meant for developers:

Hi,

I have a problem with the BeforeSaveField.
How can I do in order to avoid saving article if my test failed ?

Because I have just a warning but article still saved.

I used :

Code:

Thank you.

Saving fields is performed after item is saved so you can not cancel item saving inside this function by e.g. setting a message (with enqueueMessage) and then redirecting to some page e.g. refer (previous page)


We have another event that is triggered before saving item:
onBeforeSaveItem

and use inside a plugin of TYPE system or flexicontent:

Also in backend items.php controller a fix for redirection after error during item saving:
replace: with

Thank you.

I have a last query :
In OnBeforeSaveField, I would like to delete entirely the item saved before.
Can I get the item id related to the field with $model->get('id') ?

Is there a way to delete (e.g. a function) an item properly ?



Thank you.

mmm, we could do this:

1. If any onBeforeSaveField() call returns false then the declare the saving process as failed
2. Then the saving controller task, will call delete TASK for new items and restore version TASK for existing items

Yes. It is exactly the wished behavior
