Please how do I generate a combination of Alphanumeric(2 digits) or both Aphabets(like AA, AB, ZA) in ascending order
as shown below using yii2. Then, it can be saved in database.
A1
.
A9
B1
.
.
.
B9
.
.
.
AB
…
ZZ
Secondly, how do I get bootstrap for form wizard
Same way as you do in regular PHP:
$alphabet = range(0, 9) + range('A', 'Z');
$result = [];
foreach ($alphabet as $letter1) {
foreach ($alphabet as $letter2) {
$result[] = $letter1 . $letter2;
}
}
var_dump($result);
Haven’t got second question. Could you elaborate?
Thanks a lot. Am very grateful. You solved my problem.
However I have this little challenge, I dont want the two digits to be numeric.
It should be either Alphanumeric or alphabets, as show below.
A1
.
A9
B1
.
.
.
B9
.
.
.
AB
…
ZZ
The code you gave me generates this:
Numeric: 00, 01, …
Aphanumeric: A0, A1, …
Aphabets: AA, AB…
The Second question is, I want to do Form wizard in Yii2.
I have these models
PatientInfo
Controller
public function actionCreate()
{
$model = new PatientInfo();
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->patient_id]);
} else {
return $this->render('create', [
'model' => $model,
]);
}
}
Model
public function attributeLabels()
{
return [
'patient_id' => 'Patient ID',
'email' => 'Email',
'mobile_line' => 'Mobile Line',
'other_lines' => 'Other Lines',
'first_name' => 'First Name',
'middle_name' => 'Middle Name',
'last_name' => 'Last Name',
];
}
PatientDependant
Model
public function attributeLabels()
{
return [
'dependant_id' => 'Dependant ID',
'patient_id' => 'Patient ID',
'first_name' => 'First Name',
'middle_name' => 'Middle Name',
'last_name' => 'Last Name',
];
}
PatientMedicalInfo
Model
public function attributeLabels()
{
return [
'patient_medical_id' => 'Patient Medical ID',
'patient_id' => 'Patient ID',
'pref_med_cond' => 'Pref Med Cond',
'allergies' => 'Allergies',
'prior_surgery' => 'Prior Surgery',
'medications' => 'Medications',
];
}
It will first load the info on PatientInfo, When I click on Next, it saves and move to PatientDependant
On patientDependant, When I click on Next, it saves and move to PatientMedicalInfo. But when I click Previous, it moves back to PatientInfo.
On patientMedicalInfo, When I click on Finish, it saves and display everything on a view. But when I click Previous, it moves back to PatientDependant.
Please help me out.
Thanks
As for the generation, you got the idea. Adjusting this could should not be a huge problem.
For multi-step forms there are extension available:
<?php
$alphabet = range(‘A’, ‘Z’) + range(0, 9);
$result = [];
foreach ($alphabet as $letter1) {
foreach ($alphabet as $letter2) {
$result[] = $letter1 . $letter2;
}
}
var_dump($result);
?>
When I used this, its showing me the combination of alphabets alone. I need something like
A1…A9
. .
. .
Z1 Z9
. .
. .
AA AZ
. .
. .
ZA ZZ
Please help
