问题
I have a database table with columns ID , Country.
Inside controller i am getting the countries from model:
$countries = $countries->find('list',array('fields',array('id','country')));
$this->set('countries',$countries);
In the ctp file i am trying to get the a the dropdown by setting in option value the id and in the text the country name.
<?= $this->Form->input('Country of residence',array('type'=>'select','options'=>$countries)); ?>
The dropdown is populated by have value the id and as text the id again. How can i get the 'country' as text instead of id ?
回答1:
For 'list', you cannot provide fields array as it is just for key/value pairs. You are supposed to specify keyField and valueField instead.
$countries = $countries->find('list', ['keyField' => 'id', 'valueField' => 'country']);
Alternatively, you can set the displayField() option in your CountriesTable file to have a default valueField set for you. Default keyField would be the primary key of your table. These options would be set automatically if you bake model for the countries table. And then, you are good to go with just
$countries = $countries->find('list');
And, do not use space in the field name of your form. Go through this doc once

In your controller change this
$countries = $this->Country->find('list', array('fields' => array('id','country')));
$this->set('countries', $countries);
to
$countries = $countries->find('list',array('fields',array('id','country')));
$this->set('countries',$countries);
here i am change $country to Country(Which is Model name for Country )
And change your view ctp file
<?php echo $this->Form->input('country_of_residence',array("options"=>$countries,'type'=>'select'));?>
to
<?= $this->Form->input('Country of residence',array('type'=>'select','options'=>$countries)); ?>
here i am change field Country of residence to field country_of_residence .
its work perfect for you....
thanks
