How to retrieve the value from Drop down list into the Controller in Yii?

Question

I have a div inside a form but I'm not quite sure how to retrieve the chosen value into the controller:

<?php $form=$this->beginWidget('CActiveForm', array( 'id'=>'system-users-form', 'enableAjaxValidation'=>false, )); ?> <p class="note">Fields with <span class="required">*</span> are required.</p> <?php echo $form->errorSummary($model); ?> <button id="abutton">Already a Supplier</button> <br> &nbsp; &nbsp; <div class="row" id="toshow" style="display:none" name="suppliers"> <?php $supplier = SupplierHead::model()->findAll(); $list = CHtml::listData($supplier ,'head_id','head_name'); echo $form->DropDownList($model,'party_id', $list, array('prompt'=>'Select Supplier')); ?> </div> <script> $(document).ready(function() { $("#abutton").click(function(e){ e.preventDefault(); $("#toshow").css('display', 'block'); }); }); </script> <div class="row"> <?php echo $form->labelEx($model,'username'); ?> <?php echo $form->textField($model,'username',array('size'=>60,'maxlength'=>200)); ?> <?php echo $form->error($model,'username'); ?> </div> <div class="row"> <?php echo $form->labelEx($model,'password'); ?> <?php echo $form->passwordField($model,'password',array('size'=>60,'maxlength'=>255)); ?> <?php echo $form->error($model,'password'); ?> </div> <div class="row buttons"> <?php echo CHtml::submitButton($model->isNewRecord ? 'Create' : 'Save'); ?> </div> <?php $this->endWidget(); ?> </div><!-- form -->

Note that this row also belongs to another model. How would I retrieve this inside another controller?

Controller Code:

 public function actionCreate() { $model = new SystemUsers; $modelParties = new Parties; $modelPersons = new Persons; $supplierHead = new SupplierHead; // $modelPR = new PartyRoles; // Uncomment the following line if AJAX validation is needed // $this->performAjaxValidation($invoice); if (isset($_POST['SystemUsers'])) { $model->attributes = $_POST['SystemUsers']; Yii::app()->db->createCommand("insert into parties (party_type_id) values ('1')")->execute(); $id = Yii::app()->db->lastInsertId; $_POST["SupplierHead"]["party_id"]; $model->password = md5($model->password); $model->party_id = $id; $model->status = "Approved"; $model->date_modified = new CDbExpression('NOW()'); $email = $model->username; if($company != null) { Yii::app()->db->createCommand("insert into persons (party_id,email,company_name) values ('".$id."','".$email."','".$company."')")->execute(); } Yii::app()->db->createCommand("insert into persons (party_id,email) values ('".$id."','".$email."')")->execute(); Yii::app()->db->createCommand("insert into party_roles(party_id,role_id) values ('".$id."','2')")->execute(); /* $valid = true; $valid &= $model->validate(); $valid &= $modelParties->validate(); if($valid) { $modelParties->save(); $model->party_id = $modelParties->getPrimaryKey(); */ if($model->save()) echo ("<SCRIPT LANGUAGE='JavaScript'> window.alert('User Created') window.location.href='create'; </SCRIPT>"); // } else $this->redirect(array('views22','id'=>$model->id)); } $this->render('create',array( 'parties'=>$modelParties, 'model'=>$model, ));

}

Model for SystemUsers:

public function tableName() { return 'system_users'; } /** * @return array validation rules for model attributes. */ public function rules() { // NOTE: you should only define rules for those attributes that // will receive user inputs. return array( array('username, password', 'required'), array('isLogin', 'numerical', 'integerOnly'=>true), array('date_modified','default', 'value'=>new CDbExpression('NOW()'), ), array('date_last_login','default', 'value'=>new CDbExpression('NOW()'), ), array('date_created','default', 'value'=>new CDbExpression('NOW()'), ), array('status','default','value'=>'Approved'), array('user_role','default','value'=>'MEMBER'), array('isLogin','default','value'=>'1'), array('username', 'length', 'max'=>200), array('password', 'length', 'max'=>255), // The following rule is used by search(). // Please remove those attributes that should not be searched. ); }

EDIT

I added my model and the rest of the form to show you the confusion. The dropdown list div is value i'm trying to input into a different model and it does not exist as an attribute for system_users so It's not going through the POST.

Is filed name "party_id" exist in your table 'system_users' ? — Muhammad Shahzad

yes, party_id is the primary key in system_users. I'm trying to retrieve the head_id from the dropdown list which exists from the supplier_head table — remedy.

First make sure that your model's attribute has a safe rule. Second, in controller get a dump to see what have been sent via POST request. Do like below:

CVarDumper::dump($_POST,5678,true); Yii::app()->end();

Third, find your dropdown element in the dump you have. In Yii, You can also get a post value like below:

Yii::app()->request->getPost('YOUR DROPDOWN NAME');

UPDATE

As I said first, You must make sure that your attribute is safe. In your model add a rule like below:

array('THE NAME OF YOUR DROPDOWN','safe'),

I hope it helps.

This helped a little, but I found out that my dropdown value is not even getting posted. I updated my question to show you the entire code structure. I think the problem is that when I do a $_POST['SystemUsers'] to get the attributes from the form, the dropdown list isn't part of the attributes for system_user.

I understand what you mean about using 'safe' but I don't think you understand that the DROPDOWN is NOT a part of the model system_users so I can't add that to the rule.

Ali MasudianPour Over a year ago

Ow, Sorry. But a question, if your dropdown is not a part of your model why did you define it in view with model? I mean $form->DropDownList($model,'party_id'). Use CHtml instead of $form

Ali MasudianPour Over a year ago

If you want to do like what you wrote, you can easily add an safe attribute to your model. So what would be the problem?

@charlesisjan this depends on debugging also. Actually $_POST is an array with a collection of arrays, and further these arrays are a collection of key value pairs like

array( 'key'=>'value' )

First you need to ensure whether party_id is being submitted in the form. I am sure it is being submitted.
Now after

if (isset($_POST['SystemUsers'])) {

use

CVarDumper::Dump($_POST,100,true); die();

I am using a dummy code. it will show you the $_POST array like

array ( 'User' => array ( 'username' => 'rafasd' 'password' => 'asdfas' 'email' => '[email protected]' ) 'yt0' => '' )

in above code as user is itself an array so u can access the username as

$_POST['User']['username']

Now try to find out where does party_id is located in the $_POST array. When u find that u can access its value using above mentioned pattern

you can get as :

 $id = $_POST["SystemUsers"]["party_id"]

As per your code, drop-down name will be set as "Model_name[Field_name]".

In your action, you can see the line

$some_variable = $_POST["SystemUsers"]; // SystemUsers is model name

Can you explain a little further? I tried putting these into my controller but I'm not getting any results.

remedy. Over a year ago

Doesn't work at all. Hmm. I don't think I'm explaining my question correctly. The form has all the attributes for system_users model EXCEPT for the snippet I posted above. That one is for persons model. I'm trying to retrieve that value from the SystemUsers Controller, but none of the codes are working.

Please change your

 $_POST["SupplierHead"]["party_id"];

with this

 $_POST["SystemUsers"]["party_id"];

in your controller action create,I think error is here! Also if party_id is Your primary key then don't use in drop down, create new public variable in your model and use here in drop down.

how can i add another model inside my form? I want to call my supplier_head table

Muhammad Shahzad Over a year ago

You need to only head_id, so in your SystemUsers model create a new public variable public $headid;' and in your drop down replace this with party_id`

Muhammad Shahzad Over a year ago

In your action Create use this $_POST["SystemUsers"]["headid"]; $supplierHead->primarykey
