Cakephp 2.61 and comboboxes - mysql

Question

Using Cakephp 2.6.1, I have successfully captured and stored single characters in my database using the following code
echo $this->Form->input('grade', array('options' => array( 'G' => 'Good', 'P' => 'Pass','R'=>'Practice Required','F'=>'Fail')));
What I would like to know is how to convert these values back to the display values when retrieving them from the database, ie if the database contains 'P', I want to display 'Pass' in the view and index pages.
I'm certain the answer is simple and straightforward, and sheepishly apologise in advance for my ignorance.

Answer 1

Step-1
Create two new files under Vendor folder.
master-arrays.php
common-functions.php
and Import this two files
Process of import :
Dir : app\Config\bootstrap.php
Add this two lines:
App::import('Vendor', 'common-functions');
App::import('Vendor', 'master-arrays');
Step-2
Now open 'master-arrays.php'
and add this array
function grade_type()
{
$GRADE_TYPE['G'] = 'Good';
$GRADE_TYPE['P'] = 'Pass';
return $GRADE_TYPE;
}
Step-3
Change your view -
echo $this->Form->input('grade', array('options' =>grade_type())));
Step-4
Now add this function in 'common-functions.php'
function id_to_text($id, $arr_master=array()) {
$txt_selected = "";
$id = ''.$id; //Added this as it was creating some warnings online for wrong parameter types
if(is_array($arr_master) && array_key_exists($id,$arr_master)) {
$txt_selected = $arr_master[$id];
} else {
$txt_selected = "";
}
return $txt_selected;
}
Step-5
In Controller or in view
Input:
id_to_text('P',grade_type());
Output:
Pass

Answer 2

Try this,
// In controller
function fun()
{
$grade = array(
'G' => 'Good',
'P' => 'Pass',
'R' => 'Practice Required',
'F' => 'Fail'
);
$this->set('grade', $grade);
if ($this->request->data) {
$key = $this->request->data['Model']['grade'];
$this->request->data['Model']['grade'] = $grade[$key];
$this->Model->save($this->request->data);
}
}
// in view
echo $this->Form->input('grade', array(
'options' => $grade
));
Updated Code
// add in Model
function afterFind($results) {
foreach ($results as $key => $val) {
if (isset($val['MyModel']['status'])) {
$results[$key]['MyModel']['grade_text'] = $this->getGradeText($results[$key]['MyModel']['grade']);
}
}
return $results;
}
public function getGradeText($key)
{
$grades = array(
'G' => 'Good',
'P' => 'Pass',
'R' => 'Practice Required',
'F' => 'Fail'
);
$txt_selected = "";
if(array_key_exists($key,$grades)) {
$txt_selected = $grades[$key];
} else {
$txt_selected = "";
}
return $txt_selected;
}
// in controller
public function index() {
$this->set('data' , $this->paginate('MyModel'));
}
// in view
foreach($data as $value) {
echo $value['MyModel']['grade_text'];
}
I hope it will be help you.
