I need to get the value of a checkbox called Password using the Yii2 Framework, in the controller.
In my _form.php I define the checkbox:
<?= Html::checkbox('password', false, $options = ['label' => 'Reset password']) ?>
In my UserController.php I have the actionUpdate function:
public function actionUpdate($id)
{
$model = $this->findModel($id);
if ($model->load(Yii::$app->request->post()) && $model->save()) {
return $this->redirect(['view', 'id' => $model->id]);
} else {
echo '<pre>';
echo Yii::$app->request->post()['password'];
echo '</pre>';
return $this->render('update', [
'model' => $model,
]);
}
}
I always get the value 1 instead of true or false.
First of all, there is error in your code, it should be:
<?= Html::checkbox('password', false, ['label' => 'Reset password']) ?>
This checkbox generates 1 when checked by default. If you want to send 0 when checkbox is not selected you must add:
<?= Html::checkbox('password', false, ['label' => 'Reset password', 'uncheck' => 0]) ?>
Checkbox return 1 for true(checked) and return 0 for false(not checked).
You can check in controller as below
if(isset($model->password) && $model->password =="1") //check box is checked
{
// code
}

In my Yii application, Yii's default Ajax is not working. Also default Ajax validation is not working. Has this been an installation problem or any other problem. How to enable Yii's default Ajax.
In my controller,
public function actionCreate() {
$model = new Company;
// Uncomment the following line if AJAX validation is needed
$this->performAjaxValidation($model);
if (isset($_POST['Company'])) {
$company = Company::model()->findAll();
if (count($company) === 0) {
$model->attributes = $_POST['Company'];
$uploadedFile = CUploadedFile::getInstance($model, 'logo');
if (isset($uploadedFile)) {
$fileName = date('Ymdhis') . '_' . $uploadedFile->name; // $timestamp + file name
$model->logo = $fileName;
}
if ($model->validate()) {
if ($model->save()) {
if (isset($uploadedFile)) {
$uploadedFile->saveAs(Yii::app()->basePath . '/../banner/' . $fileName);
}
$this->redirect(array('create'));
}
}
} else {
Yii::app()->user->setFlash('error', 'Company details is already exists.');
}
}
$this->render('create', array(
'model' => $model,
));
}
In view page,
<?php
$form = $this->beginWidget('CActiveForm', array(
'id' => 'company-form',
'enableClientValidation' => true,
'clientOptions' => array(
'validateOnChange' => true,
'validateOnSubmit' => true,
),
// Please note: When you enable ajax validation, make sure the corresponding
// controller action is handling ajax validation correctly.
// There is a call to performAjaxValidation() commented in generated controller code.
// See class documentation of CActiveForm for details on this.
'enableAjaxValidation' => true,
'htmlOptions' => array('enctype' => 'multipart/form-data'),
));
?>
<div class="form-group">
<?php echo $form->label($model, 'company_name', array('class' => 'req')); ?>
<?php echo $form->textField($model, 'company_name', array('class' => 'form-control')); ?>
<?php echo $form->error($model, 'company_name', array('class' => 'school_val_error')); ?>
</div>
Please help me.
Thanks...
Yii has no default AJAX. This is a technology based on JavaScript language. By default Yii includes a jQuery library which provided some methods for easy manipulations with AJAX. If you want use it on your page, you should add this string:
Yii::app()->clientScript->registerCoreScript('jquery');
You can add this string to your main layout, for example into top of /views/layouts/main.php`
Am creating a file uploader using the kartik uploader bu the problem is that it doesn't pass extra data
The form(view) code
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'case_description')->textArea();?>
<?php echo $form->field($evidence, 'path')->widget(FileInput::classname(), [
'options' => ['accept' => '*','multiple' => true,'name'=>'images'],
'pluginOptions' => [
'browseIcon' => '<i class="glyphicon glyphicon-camera"></i> ',
'showPreview' => true,
'showCaption' => true,
'showRemove' => true,
'showUpload' => true,
'browseLabel' => 'Insert Evidence',
'uploadUrl' => Url::to(['cases/upload']),
'maxFileCount' => 10,
'uploadExtraData' => [
'album_id' => "javascript: return $('#cases-case_description').val());",
],
],
]
);?>
The $evidence ,path is a table related to the models table
The controller that I have tested with (code)
public function actionUpload(){
$ann = empty($_POST['album_id']) ? '' : $_POST['album_id'];
var_dump($ann)
}
This returns null showing that the album_id is not passed to the controller and yet the $model->case_description is the field above the upload widget
The new controller
public function actionUpload(){
$images = $_FILES['evidence'];
$success = null;
$paths= ['uploads'];
// get file names
$filenames = $images['name'];
// loop and process files
for($i=0; $i < count($filenames); $i++){
//$ext = explode('.', basename($filenames[$i]));
$target = "uploads/cases/evidence".DIRECTORY_SEPARATOR . md5(uniqid()); //. "." . array_pop($ext);
if(move_uploaded_file($images['name'], $target)) {
$success = true;
$paths[] = $target;
} else {
$success = false;
break;
}
echo $success;
}
// check and process based on successful status
if ($success === true) {
$output = [];
} elseif ($success === false) {
$output = ['error'=>'Error while uploading images. Contact the system administrator'];
foreach ($paths as $file) {
unlink($file);
}
} else {
$output = ['error'=>'No files were processed.'];
}
// return a json encoded response for plugin to process successfully
echo json_encode($output);
Due the problem with dinamic/variable assign to extraData i suggest a simple solution based on POST / submit method (eventually set the proper action in your form)
use kartik\widgets\FileInput
<?php $form = ActiveForm::begin(['options' => ['enctype' => 'multipart/form-data']]); ?>
<?= $form->field($model, 'case_description')->textArea();?>
<?php echo $form->field($evidence, 'path')->widget(FileInput::classname(), [
'options' => ['accept' => '*','multiple' => true,'name'=>'images'],
'pluginOptions' => [
'browseIcon' => '<i class="glyphicon glyphicon-camera"></i> ',
'showPreview' => true,
'showCaption' => true,
'showRemove' => true,
'showUpload' => true,
'browseLabel' => 'Insert Evidence',
'uploadUrl' => Url::to(['cases/upload']),
'maxFileCount' => 10,
],
]
);
echo Html::submitButton($model->isNewRecord ? 'Upload' : 'Update', [
'class'=>$model->isNewRecord ? 'btn btn-success' : 'btn btn-primary']
);
ActiveForm::end();
?>
I have model with below rules
public function rules()
{
return [
['student_dob',
function ($attr) {
$curr_date = date('d-m-Y');
if(empty($this->student_adm_date)) {
//$this->addError('student_dob',"Select Admission date first");
return true;
}
else {
$dob = date('Y-m-d',strtotime($this->$attr));
$adm = date('Y-m-d',strtotime($this->student_adm_date));
$diff = $adm-$dob;
if($diff <= 14) {
$this->addError('student_dob', "Birth date must be less than Admission date.");
return false;
}
else
return true;
}
},
]
];
}
This rule works good but error message don't appear on view page and my form view is below
<?php $form = ActiveForm::begin([
'layout' => 'horizontal',
'fieldConfig' => [
'template' => "{label}\n{beginWrapper}\n{input}\n{error}\n{endWrapper}",
'horizontalCssClasses' => [
'label' => 'col-sm-4',
'offset' => 'col-sm-offset-4',
'wrapper' => 'col-sm-8',
'error' => '',
'hint' => '',
],
],
]);
?>
<div class="row-left">
<?= $form->field($info, 'student_dob', ['template' => "{label} {input} <span class='status'> </span> {error}"])->widget(yii\jui\DatePicker::className(),
[
'model'=>$info,
'attribute'=>'student_dob',
'value'=>'',
'clientOptions' =>[
'dateFormat' => 'dd-mm-yyyy',
'changeMonth'=> true,
'changeYear'=> true,
'autoSize'=>true,
'showOn'=> "button",
'yearRange'=>'1900:'.(date('Y')+1),
'buttonImage'=> Yii::$app->homeUrl."images/calendar.png",
'htmlOptions'=>[
'style'=>'width:250px;',
'class'=>'form-control',
]]]); ?>
</div>
<?php ActiveForm::end(); ?>
I want to compare student_dob and student_adm_date with student_dob < student_adm_date rule validation, also error appear on form view page.
Solution
Just remove horizontalCssClasses and change template value like,
<?php $form = ActiveForm::begin([
'layout' => 'horizontal',
'fieldConfig' => [
'template' => "{label}\n{input}\n{error}",
],
]);
?>
You are subtracting one sting from another, I am not sure that works
$diff = $adm - $dob;
Try
if(strtotime($this->$attr) <= strtotime($this->student_adm_date))
Or change it to calcualte 14 days... altough not sure what you can register somebody 14 days after their birth.
You can calculate
if(strtotime($this->$attr) - strtotime($this->student_adm_date) > 60 * 60 * 24 * 14)
One more thing, in the validation functions you do not need return false; or return true; Try removing these, I personally do not know if they do anything.
I have a ajax link in yii when user click it do something and update a element html (content of td) without refresh page how can change 2 element html?
I explain more:
in view i have a table by some td for show information a td for send information (there are a image ajaxlink) and a td by message of content (example: "not send")
When user click image link call a function and valid information (...) and change message of td ('validation is success').("not send" change to "validation is success")
I did what I was told but i want to remove ajaxlink and replace it by a simple image how
can I do it?
i add:
CHtml::image(Yii::app()->theme->baseUrl . "/img/gridview/email-send.png", '', array('title' => 'sended success'))
view.php:
<td id="send_<?php echo CHtml::encode($profileInformationServices->id); ?>"><?php echo "not send"; ?></td>
<td id="sended_<?php echo CHtml::encode($profileInformationServices->id); ?>">
<?php
echo $profileInformationServices->send ? CHtml::image(Yii::app()->theme->baseUrl . "/img/gridview/email-send.png", '', array( 'title' => 'sended success')):
CHtml::ajaxLink(CHtml::image(Yii::app()->theme->baseUrl . "/img/gridview/send.png", '', array(
'title' => 'Send for valid')), Yii::app()->createUrl('/profileInformationService/send'),
array( // ajaxOptions
'type' => 'POST',
'data' => array( 'id' => $profileInformationServices->id ),
'update' => '#send_'.$profileInformationServices->id,
)
);
?>
</td>
controller:
public function actionSend() {
if (Yii::app()->request->isPostRequest) {
$model = $this->loadModel($_POST["id"]);
$model->send = 1;
$model->save();
echo "sended success";
}
}
Use ajaxLink callback to change the text in td.
<?php
//I am keeping your ternary code in if-else condition for readability
if($profileInformationServices->send)
{
echo CHtml::image(Yii::app()->theme->baseUrl . "/img/gridview/email-send.png", '', array('title' => 'sended success'));
}
else
{
echo CHtml::ajaxLink
(
CHtml::image(Yii::app()->theme->baseUrl . "/img/gridview/send.png", '', array('title' => 'Send for valid')),
Yii::app()->createUrl('/profileInformationService/send'),
array
(
'type' => 'POST',
'data' => array('id' => $profileInformationServices->id),
'success'=>'function(data)
{
if(data=="sended success")
{
$("#send_'.$profileInformationServices->id.'").html("validation is success");
}
}',
)
);
}
?>
I'm trying to perform validation in the login page for the name,email and password fields. If the input fails validation,the error message should be displayed.
But here,when I fill in the details and submit, it is redirected to the next page. Only the value is not saved in the database.
Why is the message not displayed?
This is my model:
class User extends AppModel {
var $name = 'User';
var $validate = array(
'name' => array(
'alphaNumeric' => array(
'rule' => 'alphaNumeric',
'required' => true,
'message' => 'Alphabets and numbers only'
),
'between' => array(
'rule' => array('between', 5, 15),
'message' => 'Between 5 to 15 characters'
)
),
'password' => array(
'rule' => array('minLength', '8'),
'message' => 'Mimimum 8 characters long'
),
'email_id' => 'email'
);
function loginUser($data) {
$this->data['User']['email_id'] = $data['User']['email_id'];
$this->data['User']['password'] = $data['User']['password'];
$login = $this->find('all');
foreach ($login as $form):
if ($this->data['User']['email_id'] == $form['User']['email_id'] && $this->data['User']['password'] == $form['User']['password']) {
$this->data['User']['id'] = $this->find('all',
array(
'fields' => array('User.id'),
'conditions' => array(
'User.email_id' => $this->data['User']['email_id'],
'User.password'=>$this->data['User']['password']
)
)
);
$userId=$this->data['User']['id'][0]['User']['id'];
return $userId;
}
endforeach;
}
function registerUser($data) {
if (!empty($data)) {
$this->data['User']['name'] = $data['User']['name'];
$this->data['User']['email_id'] = $data['User']['email_id'];
$this->data['User']['password'] = $data['User']['password'];
if($this->save($this->data)) {
$this->data['User']['id']= $this->find('all', array(
'fields' => array('User.id'),
'order' => 'User.id DESC'
));
$userId=$this->data['User']['id'][0]['User']['id'];
return $userId;
}
}
}
}
This is my controller:
class UsersController extends AppController {
var $name = 'Users';
var $uses=array('Form','User','Attribute','Result');
var $helpers=array('Html','Ajax','Javascript','Form');
function login() {
$userId = $this->User->loginUser($this->data);
if($userId>0) {
$this->Session->setFlash('Login Successful.');
$this->redirect('/forms/homepage/'.$userId);
break;
} else {
$this->flash('Login Unsuccessful.','/forms');
}
}
function register() {
$userId=$this->User->registerUser($this->data);
$this->Session->setFlash('You have been registered.');
$this->redirect('/forms/homepage/'.$userId);
}
}
EDIT
Why is the message,example,"Minimum 8 characters long", is not being displayed when give less than 8 characters in the password field?
<!--My view file File: /app/views/forms/index.ctp -->
<?php
echo $javascript->link('prototype.js');
echo $javascript->link('scriptaculous.js');
echo $html->css('main.css');
?>
<div id="appTitle">
<h2> formBuildr </h2>
</div>
<div id="register">
<h3>Register</h3>
<?php
echo $form->create('User',array('action'=>'register'));
echo $form->input('User.name');
echo $form->error('User.name','Name not found');
echo $form->input('User.email_id');
echo $form->error('User.email_id','Email does not match');
echo $form->input('User.password');
echo $form->end('Register');
?>
</div>
<div id="login">
<h3>Login</h3>
<?php
echo $form->create('User',array('action'=>'login'));
echo $form->input('User.email_id');
echo $form->input('User.password');
echo $form->end('Login');
?>
</div>
Your validation seems correct
How about trying the following:
Make sure set your $form->create to the appropriate function
Make sure there is no $this->Model->read() before issuing Model->save();
Edit
Did you have the following?:
function register()
{
//do not put any $this->User->read or find() here or before saving pls.
if ($this->User->save($this->data))
{
//...
}
}
Edit2
IF you're doing a read() or find() before saving the Model then that will reset the fields. You should be passing the variable as type=hidden in the form. I hope i am making sense.
Edit3
I think you need to move your registerUser() into your controller because having that function in the model doesn't provide you a false return. it's always going to be true even if it has validation errors.
Comment out the redirect line and set the debug to 2 in config/core.php. Then look at the sql that is being generated to see if your insert is working. If the errors are not being displayed, maybe in the view, you are using $form->text or $form->select instead of the $form->input functions. Only the $form->input functions will automatically display the error messages.
