Re: Exclude Array Item on Save
you can also use the $fieldList parameter in the $modelName->save
http://api.cakephp.org/1.2/class_model.html#ebe42ae387be89985b5a35dd428f5c81
Model::save ( $ data = null,
$ validate = true,
$ fieldList = array()
)
Saves model data to the database. By default, validation occurs before save.
Parameters:
array $data Data to save.
boolean $validate If set, validation will be done before the save
array $fieldList List of fields to allow to be written

Try putting the code that unsets that element in the array in a
beforeSave() method in the model.

Exclude Array Item on Save
Hiya,
I've got a simple image upload form in which the user can come back
and update the image, as well as name, description etc.
The issue I'm having is that when they come back to only update the
description, I don't want the original image to be overridden.
So I first thought that I could just unset the array item. For
example:
if (!$this->data['Home']['image']['name']) {
unset($this->data['Home']['image']);
}
However, the Cake save() function still overrwrites the old image in
the DB.
How do you all accomplish this in your forms? Is there a CakePHP
syntax to tell it to not update a field?
I'm using the latest 1.2x from the SVN.
Many thanks!
Wilson
