Question

I need to run a save/update query but only update those fields that aren’t empty. My form contains a FILE field and if I don’t upload any file then when the save() is executed this field goes blank even if previous data is presented so how can I save/updated but onlye the fields with content to update?

Cheers and thanks in advance

Answer 1

In your model you need to previously test if the data is empty or not and unset it in this case.

if ($this->data['file'] == "") {
    unset($this->data['file']);
}
