Hi,
Suppose this is image field
<?php echo $this->Form->input('MyModel.image',array('type'=>'file')); ?>
In edit action just check,if you upload any photo or not
if(empty($this->data['MyModel']['image']['name']))
{
unset($this->data['MyModel']['image']);
$this->data['MyModel']['image']='old_field_value(old image name saved in
database)';
}
else
{
//logic for upload new file and replace the old one
}
Try this , i think it will help you.
Thanks
Timir Maji
