Hi,

is it possible, before save a page, to copy data from one field to another field?
That is I've a field A and a field B. After compiled A and leave field A, value of A must be filled in field B.

Thank you

Into product.php controller, I write:

protected function onBeforeWrite() {

parent::onBeforeWrite();

if ($this->ID) {

$this->record['QuotaDisponibile'] = $this->record['PriceProduct'];
// fill in MetaDescription without any tags

if ($this->record['Content']) {

$this->record['MetaDescription'] = strip_tags($this->record['Content']);
}

if ($this->record['Content']) {

$this->record['MetaKeywords'] = self::calculateKeywords($this->record['Content'], 4, 15);
}
}

$this->record['QuotaDisponibile'] = $this->record['PriceProduct'];
}

but don't work?
How can view debug? Is there a debug type Visual Studio? -:)

If I remember correctly $this->record refers to the database record and since this is onBeforeWrite it hasn't been written to the database yet. Instead of writing $this->record['QuotaDisponibile'] do $this->QuotaDisponibile instead. The same goes for all your other $this->record calls.

Hi,

I have made something similar. In your function onBeforeWrite, you have to retrieve the value of the field, and after that you can copy it to the new field. Here you have the functions I have used:

function onBeforeWrite(){
$firstField = $this->getField('yourFieldName');
$this->setField('yourNewFieldName', $firstField);

/*You can also use the setCastedField function*/

parent::onBeforeWrite();
}

Hope this will help you!

Regards,
