Undefined variable in Laravel view - select

I have tried to get a solution for this for hours and I really do not understand why it's not working.
routes.php
Route::get("/user/Session::get('theuser')/charname", array(
'as' => 'profile-character',
'uses' => 'ProfileController#dropDownList'
));
ProfileController.php
public function dropDownList() {
$list = Character::lists('char_name', 'char_dynasty');
return View::make('layout.profile')->with('character_options',$list);
}
profile.blade.php
<div class="selected_char">
<form action="{{ URL::route('profile-character') }}" method="get">
{{ Form::select('character', $character_options , Input::old('character')) }}
</form>
</div>
This code throws me the error that the $character_options is undefined. I have read dozens of examples doing the same thing like me and working for them. Maybe this is Laravel 3?

This is something that should not work on Laravel:
Route::get("/user/Session::get('theuser')/charname", array(
'as' => 'profile-character',
'uses' => 'ProfileController#dropDownList'
));
You cannot have a call like Session::get() in your route, not as far as I know at least. Your route will work because it's a string valid for route, but that Session::get() will never really be used in the process.
If you literally hit the url:
http://localhost/user/Session::get('theuser')/charname
What you can have is something like:
Route::get("/user/{user}/charname", array(
'as' => 'profile-character',
'uses' => 'ProfileController#dropDownList'
));
And do
public function dropDownList($user) {
$list = Character::lists('char_name', 'char_dynasty');
return View::make('layout.profile')->with('character_options',$list);
}

can't pass parameter from view to controller

Hi all I am currently working with zend 2.3. and while listing students I am trying to make link that allows to show detales about selected person. My problem is that I can't pass selected id to the action in module's controller. Here is my view's code that coresponds to link:
<a href="<?php echo $this->url('admin' ,
array( 'controller'=>'Admin', 'action'=>'viewstudent', 'ID' => $student->ID))."/admin/viewstudent";?>">detales</a>
and the action in controller
public function viewstudentAction ()
{
$id = (int) $this->params()->fromRoute('ID', 0);
echo $id;
//echo var_dump($id);
return new ViewModel(array(
'students' => $this->getStudentTable()->viewstudent($id),
));
}
Then I var_dump $id variable it shows 0 So what is the correct way to do this?
I have edited the a href's code like this
<a href="<?php echo $this->url('admin/default' ,
array( 'controller'=>'Admin', 'action'=>'viewstudent', 'id' => $student->ID));?>">Просмотр</a>
and it resolves to this:
Просмотр
url is
http://localhost:8080/disability/public/admin/Admin/viewstudent
The url is
http://localhost:8080/disability/public/admin/Admin/viewstudent
Problem is the same id didn't pass
I have found the solution to the problem. I passed the parameter using query here is how it looks in view file
<a href="<?php echo $this->url('admin/default',
array('controller' => 'Admin',
'action'=>'viewstudent'
),
array('query' =>
array('id' => $student->ID)
)
);
?>">view</a>
And then using $this->params retrieve it in my controller file
$id = $this->params()->fromQuery('id');

cakephp 3: change class input error

I build my form template according the documentation. It seemed everything was fine until I get fields errors. Now I have two problems:
How can I change the class name of the forms fields when they get error?
Solution:
$this->loadHelper('Form', [
'templates' => 'your_template_file',
'errorClass' => 'your-class',
]);
How can I set escape => false in the error-message from cakephp, when the field get error? Because I have icon within that div, such as
<div class="error-message"><i class="fa fa-times"></i> My error</div>
Well, I got part of th solution. To escape HTML I could put $this->Form->error('field', null, ['escape' => false]); in all fields, but it´s a hard manually task. I´d like to keep escape with default of all fields errors. I could edit the FormHelper.php class. However, I think that is not good idea.
My form template is:
'formStart' => '<form {{attrs}} class="form-horizontal" novalidate>',
'inputContainer' => '{{content}}',
'input' => '<input type="{{type}}" name="{{name}}" {{attrs}} class="form-control"/>',
'checkbox' => '<input type="checkbox" value="{{value}}" name="{{name}}" {{attrs}}/>',
'textareaContainerError' => '{{content}}',
'textarea' => '<textarea name="{{name}}" {{attrs}} class="form-control"></textarea>',
'select' => '<select name="{{name}}" {{attrs}} class="form-control">{{content}}</select>',
'button' => '<button {{attrs}} class="btn btn-primary">{{text}}</button>',
'nestingLabel' => '{{input}}',
'formGroup' => '{{input}}',
to the second part of the question: you can extend FormHelper like in code below, so that escape will be set to false by default
// extended FormHelper, this goes in src/View/Helper
namespace App\View\Helper;
use Cake\View\Helper;
class MyFormHelper extends Helper\FormHelper
{
public function error($field, $text = null, array $options = [])
{
if (!isset($options['escape'])) {
$options['escape'] = false;
}
return parent::error($field, $text, $options);
}
}
next create alias for this helper in AppController.php
public $helpers = [
'Form' => ['className' => 'MyForm']
];
this also allows you to add more customization of your own and at any time, you can go back to default implementation of FormHelper, just remove that alias from AppController.php.
For those who wants an 'easy solution' to escape error message on some fields, you cant simply set escape options to false :
<?= $this->Form->input('email', [
"label" => "Email",
"error" => [
"escape" => false
]
]) ?>

Phalcon use Phalcon\Tag OR Phalcon\Forms for creating forms

I searched up and down but couldn't find which one is better Phalcon\Tag OR Phalcon\Forms for creating forms.
Both classes have functionality to create form elements. But I found there are some handy tags in the Phalcon\Tag, for example Phalcon\Tag::emailField() or Phalcon\Tag::dateField(array())
Phalcon documentation says:
"Phalcon\Forms is a component that aid the developer in the creation
and maintenance of forms in web applications."
"Phalcon\Tag is designed to simplify building of HTML tags. It
provides a set of helpers to generate HTML in a dynamic way."
Can anybody help me with the pros and cons of using both the methods.
Thanks
In simple meaning Phalcon\Tag are used to design only html (users view). but for validation && adding rules to the form you need to use phalcon\forms i will show you an example of phalcon\forums below
NEW FORM CLASS:
use Phalcon\Forms\Form,
Phalcon\Forms\Element\Password,
Phalcon\Forms\Element\Email as Emailfield,
Phalcon\Forms\Element\Check,
Phalcon\Forms\Element\Hidden,
Phalcon\Validation\Validator\PresenceOf,
Phalcon\Validation\Validator\Identical,
Phalcon\Validation\Validator\Email;
class LoginForm extends Form
{
public function initialize()
{
$email = new Emailfield('email', array(
'placeholder' => 'Type your Email'
));
$email->setLabel('E-Mail');
$email->setFilters('email');
$email->addValidators(array(
new PresenceOf(array(
'message' => 'E-mail is required'
)),
new Email(array(
'message' => 'E-mail is not valid'
))
));
$this->add($email);
$password = new Password('password', array(
'placeholder' => 'Type your Password'
));
$password->setLabel('Password');
$password->setFilters(array('striptags', 'string'));
$password->addValidators(array(
new PresenceOf(array(
'message' => 'Password required'
))
));
$this->add($password);
//Remember
$long_login = new Check('long_login', array(
'value' => 'yes'
));
$long_login->setLabel('Keep me logged in');
$this->add($long_login);
// CSRF
$csrf = new Hidden('csrf');
$csrf->addValidator(new Identical(array(
'value' => $this->security->getSessionToken(),
'message' => 'CSRF validation failed'
)));
// $this->add($csrf);
}
}
In Controller:
$form = new LoginForm();
if (!empty($_POST)) {
if (!$form->isValid($_POST)) {
$errors = array();
foreach ($form->getMessages() as $message) {
$errors[] = $message;
}
if (!empty($errors))
$this->flash->error(join('<br/>', $errors));
} else {
//Login Continues
}
}
$this->view->setVar('form', $form);
To convert this form to html below is the code:
<div class="form-group">
{{ form.label('email',['class': 'control-label']) }}
{{ form.render('email', ['class': 'form-control input-md']) }}
</div>
<div class="form-group">
{{ form.label('password',['class': 'control-label']) }}
{{ form.render('password', ['class': 'form-control input-md']) }}
</div>
<div class="checkbox">
{{ form.render('long_login') }}
{{ form.label('long_login') }}
</div>
Really great example in general but I'm struggling with the flash message. After a quick google search I was more confused after reading the documentation. Some say that $this->flash->output() should be placed to the view to see the flash messages. Though this causes errors and I believe it's something from the past. Can somebody tell me what flash method should I place to view to see the flash messages or Where I'm going wrong?
EDIT: Well I managed to get \Phalcon\Flash\Session to work and I believe it's event more suitable for me than Direct. For that you need to register flash service in Dependency Injector in config/services.php. I also replaces classes with bootstrap classes.
$di->set('flash', function() {
return new Phalcon\Flash\Session(array(
'error'=>'text-danger',
'warning'=>'text-warning',
'notice'=>'text-info',
'success'=>'text-success'
));
});
It depends on which you are working.
If we say, you need to insert lots of data with lots of validations and it may change during progress then its far better to use "Phalcon\Forms"
As they are very dynamic.
Means you can change text-box with select box very easily without touching template.
You can add validations without worrying about template and other stuff.
And for-most reusable you can reuse form if you need.
so if there is less data then you are free to use anyone of that but more suggestible is "Phalcon\Forms" its very dynamic and structural.

zend framework - group elements of a form within a subforms [duplicate]

I would like to be able to add a hidden form field using array notation to my form. I can do this with HTML like this:
<input type="hidden" name="contacts[]" value="123" />
<input type="hidden" name="contacts[]" value="456" />
When the form gets submitted, the $_POST array will contain the hidden element values grouped as an array:
array(
'contacts' => array(
0 => '123'
1 => '456'
)
)
I can add a hidden element to my form, and specify array notation like this:
$form->addElement('hidden', 'contacts', array('isArray' => true));
Now if I populate that element with an array, I expect that it should store the values as an array, and render the elements as the HTML shown above:
$form->populate($_POST);
However, this does not work. There may be a bug in the version of Zend Framework that I am using. Am I doing this right? What should I do differently? How can I achieve the outcome above? I am willing to create a custom form element if I have to. Just let me know what I need to do.
You have to use subforms to get the result you seek. The documentation was quite a ride but you can find it here
Using what I found there I constructed the following formL
<?php
class Form_Test extends Zend_Form {
public function init() {
$this->setMethod('post');
$this->setIsArray(true);
$this->setSubFormDecorators(array(
'FormElements',
'Fieldset'
));
$subForm = new Zend_Form(array('disableLoadDefaultDecorators' => true));
$subForm->setDecorators(array(
'FormElements',
));
$subForm->addElement('hidden', 'contacts', array(
'isArray' => true,
'value' => '237',
'decorators' => Array(
'ViewHelper',
),
));
$subForm2 = new Zend_Form(array('disableLoadDefaultDecorators' => true));
$subForm2->setDecorators(array(
'FormElements',
));
$subForm2->addElement('hidden', 'contacts', array(
'isArray' => true,
'value' => '456', 'decorators' => Array(
'ViewHelper',
),
));
$this->addSubForm($subForm, 'subform');
$this->addSubForm($subForm2, 'subform2');
$submit = new Zend_Form_Element_Submit('submit');
$submit->setValue('Submit');
$this->addElement('submit', 'submit');
}
}
Wich outputs this html:
<form enctype="application/x-www-form-urlencoded" method="post" action=""><dl class="zend_form">
<input type="hidden" name="contacts[]" value="237" id="contacts">
<input type="hidden" name="contacts[]" value="456" id="contacts">
<dt id="submit-label"> </dt><dd id="submit-element">
<input type="submit" name="submit" id="submit" value="submit"></dd></dl></form>
And when submited the post looks like:
array(2) {
["contacts"] => array(2) {
[0] => string(3) "237"
[1] => string(3) "456"
}
["submit"] => string(6) "submit"
}
So thats how you can create the kind of forms you seek. Hope this helps! if you have a question post a comment!
Its quite hackish if you ask me. You basically create subforms but disable there form decorators so just the element gets output. Since the identical contacts[] elements are in different form object zend does'nt overwrite them and it works. But yeah..
Edit: changed it a bit to remove labels and garbage arount the hidden inputs.
To use array notation, you need to specify that the element "belongs to" a parent array:
$form->addElement('hidden', 'contact123', array('belongsTo' => 'contacts', 'value' => '123'));
$form->addElement('hidden', 'contact456', array('belongsTo' => 'contacts', 'value' => '456'));
This indeed seems to be a bug in Zend Framework - the value attribute for an element is properly set to array, but it's ignored when the element renders - it just uses$this->view->escape($value) to output element's html.
I've solved this by implementing a custom helper for such elements:
class My_View_Helper_HiddenArray extends Zend_View_Helper_FormHidden
{
public function hiddenArray($name, $value = null, array $attribs = null)
{
if (is_array($value)) {
$elementXHTML = '';
// do not give element an id due to the possibility of multiple values
if (isset($attribs) && is_array($attribs) && array_key_exists('id', $attribs)) {
unset($attribs['id']);
}
foreach ($value as $item) {
$elementXHTML .= $this->_hidden($name, $item, $attribs);
}
return $elementXHTML;
} else {
return $this->formHidden($name, $value, $attribs);
}
}
}
Which, when used the next way:
$contacts = $form->createElement('hidden', 'contacts')
->setIsArray(true)
->setDecorators(array(
array('ViewHelper', array('helper' => 'HiddenArray')),
));
$form->addElement($contacts);
generates the needed output.
The reason to extend Zend_View_Helper_FormHidden here is just to be able to call the default behaviour if no array value is set ( return parent::formHidden($name, $value, $attribs) ).
Hope this helps someone :)
