Saving a Disabled field

问题

In my edit.ctp I have a select box which I don't need the user to change. So I put array(disabled=>true). But this field is not coming when

pr($this->data); and showing an error while saving.

What options are there to solve this issue.

回答1:

You could make the field readonly so that user cant change it , or use some hidden field to post the data that you want, or you could use some css, like visibility:hidden, so that user dont see it but it'll be posted.

echo this->Form->input('patient_id',array('type'=>'hidden'));   

You can use some other name for the input and check in controller, or you could completely remove the select element from the view*strong text* (since, its not needed as user dont need to change it)

回答2:

If you know the value of the data you can edit it at the controller.

$this->request->data['ModelName']['fieldName'] = value;

UPDATE

Edit it like
echo $this->Form->input('patient_id',array('type'=>'select', 'readonly' => 'readonly'));
