I am storing the username and password in cookie but i have little trouble with remember me button i want that when user check the check box the cookie store the values else only log in the user but the problem is here when i put the check in my controller it wont work i know the problem is in my if condition please some one sort me out the problem or correct my syntax will be really thankful. Here is my code of controller and view.
function verifying(){
$data=array(
'username'=>$this->input->post('username'),
'password'=>$this->input->post('password')
);
if($this->input->post('remember_me')=="checked")
{
$cookie = array(
'name' => 'username',
'value' => $this->input->post('username'),
'expire' => 86500,
'secure' => false
);
$cookie1 = array(
'name' => 'password',
'value' => $this->input->post('password'),
'expire' => 86500,
'secure' => false
);
}
$this->input->set_cookie($cookie);
$this->input->set_cookie($cookie1);
$result=$this->user->verify("signup",$data);
if($result)
{
$sess_arrau=array();
foreach($result as $row)
{
$sess_arrau=array('username'=>$row->username);
}
$this->session->set_userdata($sess_arrau);
$data['username']=$this->session->userdata('username');
$this->load->view("success",$data);
}
//$this->load->view("success",$sess_array);
else{
redirect("signin");
}
}
Log in page code.
<?php
$username=$this->input->cookie('username', false);
$password=$this->input->cookie('password',false);
if($this->session->userdata('username')!=''){
redirect("index/post");
}
echo form_open("index/verifying");
echo form_input('username',"$username",'placeholder="username"');
echo form_checkbox('remember_me','REMEMBER ME',FALSE);
echo form_label('REMEMBER ME','remember_me');
?>
</div>
</div>
<div class="row">
<div class="col-lg-12">
<?php
echo form_password('password',"$password",'placeholder="password"');
echo form_submit('submit','Signin');
echo form_close();
?>
Your problem is that "checked" won't be the value of the input when it has been checked. Instead the value will be "REMEMBER ME" because this is the second parameter you have passed to the form_checkbox function.
So in your controller rather than do
if($this->input->post('remember_me')=="checked")
{
//Do stuff here...
}
You need to do
if($this->input->post('remember_me')=="REMEMBER ME")
{
//Do stuff here...
}
quite easy the answer above is correct too and the other short approach is like that.
if($this->input->post('remember_me')!="")
And it will work fine too.

I have a Single page application in Yii2
the main page contains
1. a column with a list of objects + create button
2. a column for dynamic content of create/update forms
My problem is when loading (through ajax) a create form, and then I am sending data through AjaxSubmitButton which woks fine (db updated) but instead of changing the dynamic content area with the new object data it redirects to a view partial form.
How can I make the new response go into the same div that it is being sent from?
this is the form that is loaded now in #singleObjContainer
<div class="course-form">
<?php
$form = yii\bootstrap\ActiveForm::begin();
?>
<span>
<h4 class='listTitle'>Add Course</h4>
</span>
<span class="form-group pull-right">
<?php
AjaxSubmitButton::begin([
'label' => 'Save',
'ajaxOptions' => [
'type'=>'POST',
'url'=> Url::toRoute(['course/create-form']),
'success' => new \yii\web\JsExpression('function(html)
{
$("#singleObjContainer").empty().append(html);
}'),
],
'options' => ['class' => 'btn btn-success', 'type' => 'submit'],
]);
AjaxSubmitButton::end();
?>
</span>
<hr class='myHr'>
<div>
<?php
echo $form->field($model, 'name')->textInput(['maxlength' => true]);
echo $form->field($model, 'description')->textarea(['rows' => '4']);
echo $form->field($model, 'img')->label(Html::img(Yii::getAlias('#uploadsUrl/').'courses/'.$model->img,['width' => '30%']),['encodeLabel' => false])->fileInput();
?>
</div>
<?php ActiveForm::end(); ?>
and this is the controller action:
public function actionCreateForm()
{
$model = new Course();
if ( $model->load(Yii::$app->request->post()))
{
// get the instance of the image
$image = UploadedFile::getInstance( $model, 'img');
// save image name to the model
$model->img = $image->baseName.".".$image->extension;
// go through validation rule and save
if( $model->save() )
{
// validation ok, save image in the file system
$image->saveAs( Yii::getAlias('#uploads/').'courses/'.$model->img);
// load the details view into the singleObj container
$courseStudents = $this->getCourseStudents($model['id']);
return $this->renderPartial('_viewForm', ['model' => $model, 'courseStudents' => $courseStudents]);
}
}
else
{
return $this->renderPartial('_createForm', ['model' => $model,]);
}
}
If you need that your result is send directly to the ajax request .. just return .. eventually using a json_encode for the array.
return json_encode( $model);
this way you obtain a json answer with struct equivalent to your $model
In your controller add a proper action
public function actionRefreshForm()
{
//your appllication code
$my_new_html_code ='<div>test new html code </div>;
return $my_new_html_code;
}
In your ajaxOptions call the related action
'ajaxOptions' => [
'type'=>'POST',
'url'=> Url::toRoute(['course/refresh-form']),
'success' => new \yii\web\JsExpression('function(html)
{
$("#singleObjContainer").empty().append(html);
}'),
],
You can use yii\widgets\Pjax. It will be easy for you I guess. You can learn more about it in this article. http://blog.neattutorials.com/yii2-pjax-tutorial.
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(

// 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 $form->textField($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`
I'm tring to validate a login form and sending error messages using flashdata. Flashdata seems to have a delay, it's only affected a second submit (no error message is shown after first submit, ok after second), whereas userdata works correctly.
View>
<?php if ($this->session->flashdata('error_messages')): ?>
<?php echo $this->session->flashdata('error_messages'); ?>
<?php endif; ?>
<?php echo form_open('user/login', array('name' => 'login_form', 'id' => 'login_form')); ?>
<fieldset>
<p>
<?php echo form_label('Username: ', 'username'); ?>
<?php echo form_input('username', set_value('username', ''), array('id' => 'username', 'placeholder' => 'username')); ?>
</p>
<p>
<?php echo form_label('Password: ', 'password'); ?>
<?php echo form_password('password', set_value('password', ''), array('id' => 'password', 'placeholder' => '********')); ?>
</p>
<p>
<?php echo form_submit('login', 'Login', array('id' => 'login')); ?>
</p>
Controller action>
public function login() {
//user is not logged in, carry on
if (!user_is_logged_in()) {
//check if form was already submitted, if yes validate
if ($this->input->post('login')) {
$this->load->library('chronos_user');
//gather data from form
$username = $this->input->post('username');
$password = $this->input->post('password');
//validate form, show error messages if not valid
if (
!($this->chronos_user->valid_username($username)) ||
!($this->chronos_user->unique_username($username))
)
{
$this->chronos_template->set_data('header', array('controller' => 'users', 'action' => 'login', 'title' => 'Login'));
$this->chronos_template->set_view('content', 'user/login_view');
$this->chronos_template->view();
}
//redirect if ok
else {
header("Location http://c4studio.ro");
}
}
//if no form was submitted, just display it

$this->chronos_template->set_data('header', array('controller' => 'users', 'action' => 'login', 'title' => 'Login'));
$this->chronos_template->set_view('content', 'user/login_view');

//user is already logged in, redirect to profile page
else {
$profile_url = "Location: ";
$profile_url .= site_url();

return FALSE;
}
return TRUE;
}
Any ideas? Also if somebody knows a better way to do all this please let me know! Thanks
According to the documentation flashdata exists at the next server request.
But in your case you actually set the flashdata in the same server request as you show the login view which was unsuccesful. Thats the reason it doesn't work.
A better way wuld to just allow your model method to return true or false and use that value instead. The flashdata should only be considered if you redirect the user to an error page or something like that.
As #Repox mentioned, it only works on the 'next refresh'. You are assuming that flashdata works RIGHT AWAY when you set it, but it doesn't you need an new actual page reload / refresh before that is available.
You have the right idea, but you are just using flashdata to implement your message, stick to form messages as a return result, or just a custom variable.
This is really a case of developers designing flashdata for one thing, and users using it for another.
You need to use form_error to return all form errors, don't use flashdata, it will not work as you expect it to.
Examples:
http://codeigniter.com/user_guide/libraries/form_validation.html#settingerrors
You can also override any error message found in the language file.
For example, to change the message for the "required" rule you will do
this:
$this->form_validation->set_message('required', 'Your custom message here');
let's say I have a blog with a module "post".
now I display a post like this: post/index?id=1
in the index-action i generate a new CommentForm and pass it as $this->form to the template and it is being displayed at the bottom of a post (it's just a textfield, nothing special). form action is set to "post/addcomment". How can I display the validation errors in this form? using setTemplate('index') doesn't work because I would have to pass the id=1 to it...
thanks
UPDATE:
here's a sample code:
public function executeIndex(sfWebRequest $request)
{
$post = Doctrine::getTable('Posts')->find($request->getParameter('id'));
$this->post = $post->getContent();
$comments = $post->getComment();
if ($comments->count() > 0)
$this->comments = $comments;
$this->form = new CommentForm();
$this->form->setDefault('pid', $post->getPrimaryKey());
}
public function executeAddComment(sfWebRequest $request) {
$this->form = new CommentForm();
if ($request->isMethod('post') && $request->hasParameter('comment')) {
$this->form->bind($request->getParameter('comment'));
if ($this->form->isValid()) {
$comment = new Comment();
$comment->setPostId($this->form->getValue('pid'));
$comment->setComment($this->form->getValue('comment'));
$comment->save();
$this->redirect('show/index?id='.$comment->getPostId());
}
}
}
and my Comment Form:
class CommentForm extends BaseForm {
public function configure() {
$this->setWidgets(array(
'comment' => new sfWidgetFormTextarea(),
'pid' => new sfWidgetFormInputHidden()
));
$this->widgetSchema->setNameFormat('comment[%s]');
$this->setValidators(array(
'comment' => new sfValidatorString(
array(
'required' => true,
'min_length' => 5
),
array(
'required' => 'The comment field is required.',
'min_length' => 'The message "%value%" is too short. It must be of %min_length% characters at least.'
)),
'pid' => new sfValidatorNumber(
array(
'required' => true,
'min' => 1,
'max' => 4294967295
),
array(
'required' => 'Some fields are missing.'
))
));
}
}
and finally, indexSuccess:
<?php echo $post; ?>
//show comments (skipped)
<h3>Add a comment</h3>
<form action="<?php echo url_for('show/addComment') ?>" method="POST">
<table>
<?php echo $form ?>
<tr>
<td colspan="2">
<input type="submit" />
</td>
</tr>
</table>
</form>
that's it.
If you're using sf 1.4 just put executeAddComments and executeIndex together in one function (executeIndex for example) and you'll be fine. setTemplate won't work here.
Are you using the handleError method in the action ? The id=1 part of your url should not change if inside the handleError method, you do a return sfView::SUCCESS;
UPDATE:
It actually changes, what you need to do is submit the id along with the comment [Which I'm sure you're already doing because a comment that doesn't refer to a post doesn't make much sense], then in your handleError method, instantiate the post object there.
Try to change your form action to
<?php echo url_for('show/addComment?id=' . $post->getId()) ?>
Doing this, your post id parameter should be available even on your post request, and it should work with setTemplate('index') or forward at the end of executeAddComment
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?

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.
