I have a controller with a add() function and create() function. The add function posts to create.
The form is displayed using the form helper. In the add() function, I have an array to set the form input attributes that looks like the following:
$this->data['form'] = array(
'label_attributes' => array(
'class' => 'col-lg-2 control-label'
),
'media_name' => array(
'class' => 'form-control',
'id' => 'media_name',
'name' => 'media_name',
'value' => set_value('media_name')
),
'media_link' => array(
'class' => 'form-control',
'id' => 'media_link',
'name' => 'media_link',
'value' => set_value('media_link')
),
'media_width' => array(
'class' => 'form-control',
'id' => 'media_width',
'name' => 'media_width',
'size' => '4',
'maxlength' => '4',
'value' => ($this->form_validation->set_value('media_width')) ? $this->form_validation->set_value('media_width') : '640'
),
'media_height' => array(
'class' => 'form-control',
'id' => 'media_height',
'name' => 'media_height',
'value' => ($this->form_validation->set_value('media_height')) ? $this->form_validation->set_value('media_height') : '360'
),
'media_description' => array(
'class' => 'form-control',
'id' => 'media_desription',
'name' => 'media_desription',
'value' => $this->form_validation->set_value('media_desription')
)
);
When I post to the create() function, I lose access to the data['form'] values. Should all this information just be in the view or is it possible to put it in the model so I can load it whenever needed? When I tried to put it in the model, I had issues with the 'value' attributes even if I loaded the form_validation library in the model.
Because the controller class is renewed when a new request comes, so the problem with your code is that, $this->data is created when you visit the add function, while when you post to create function, the controller class is renewed again, there is no $this->data at all at this time.
If you want to pass data from one request to another request, you can pass the data via view or model.
Hope helps!

I want to create the following element :
<input type="file" name="file[]">
I have tried the following code in myproject/module/Member/src/Member/Form/EditForm.php :
$this->add(array(
'name' => 'file',
'type' => 'file',
'attributes' => array(
'class' => 'form-control col-md-7 col-xs-12',
'id' => 'file',
),'options' => array(
'multiple'=>TRUE
),
));
and
$this->add(array(
'name' => 'file[]',
'type' => 'file',
'attributes' => array(
'class' => 'form-control col-md-7 col-xs-12',
'id' => 'file',
),'options' => array(
'multiple'=>TRUE
),
));
but it is not working.
For file upload Zend Framework 2 has a special FileInput class.
It is important to use this class because it also does other important things like validation before filtering. There are also special filters like the File\RenameUpload that renames the upload for you.
Considering that $this is your InputFilter instance the code could look like this:
$this->add(array(
'name' => 'file',
'required' => true,
'allow_empty' => false,
'filters' => array(
array(
'name' => 'File\RenameUpload',
'options' => array(
'target' => 'upload',
'randomize' => true,
'overwrite' => true
)
)
),
'validators' => array(
array(
'name' => 'FileSize',
'options' => array(
'max' => 10 * 1024 * 1024 // 10MB
)
)
),
// IMPORTANT: this will make sure you get the `FileInput` class
'type' => 'Zend\InputFilter\FileInput'
);
To attach file element to a form:
// File Input
$file = new Element\File('file');
$file->setLabel('My file upload')
->setAttribute('id', 'file');
$this->add($file);
Check the documentation for more information on file upload.
Or check the documentation here on how to make an upload form
there are 2 columns check box in cgridViewtable and two bootstrap widgets TbButton in view page.
I can not get value of my checkbox very good. My value in checkboxs transfer into controller but changed id of checkboxs After a period of timeand , and controller don't knew checkbox,
View:
$form = $this->beginWidget('bootstrap.widgets.TbActiveForm', array(
'id' => 'profile-information-form',
'enableAjaxValidation' => false,
));
$this->widget('bootstrap.widgets.TbButton', array('buttonType' => 'submit', 'type' => 'primary', 'label' => Yii::t('fa_ir', 'First validation'),));
$this->widget('bootstrap.widgets.TbButton', array('buttonType' => 'submit', 'type' => 'primary', 'label' => Yii::t('fa_ir', 'End validation'),));
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'profile-information-grid',
'dataProvider' => $model->children(),
'filter' => $model,
'columns' => array(
array(
'header' => '',
'value' => '$this->grid->dataProvider->pagination->offset + $row+1', // row is zero based
),
array(
'name' => 'ProfileInformation.user.scope',
'value' => 'CHtml::encode($data->user->scope->name)',
'filter' => Scope::model()->options,
),
array(
'name' => 'id',
'value' => 'CHtml::encode($data->id)',
),
array(
'name' => 'center',
'value' => 'CHtml::encode($data->center)',
),
array(
'name' => 'sendCount',
'value' => 'CHtml::encode($data->sendCount)',
'filter' => '',
),
// Use CCheckbox column with selectableRows = 2 for Select All
array('class' => 'CCheckBoxColumn', 'selectableRows' => 2, 'visible' => (Lookup::isUser2(Yii::app()->user->id) or Lookup::isAdmin(Yii::app()->user->id))),
array('class' => 'CCheckBoxColumn', 'selectableRows' => 2, 'visible' => (Lookup::isUser1(Yii::app()->user->id) or Lookup::isAdmin(Yii::app()->user->id))),
),
));
// action button
$this->endWidget();
Controller:
if (isset($_POST['profile-information-grid_c10']) & isset($_POST['yt0'])) {
////Do action1
}
if (isset($_POST['profile-information-grid_c12']) & isset($_POST['yt1'])) {
////Do action2
}
}
my problem is in $_POST['profile-information-grid_c10'] and _POST['profile-information-grid_c12'] , before id were $_POST['profile-information-grid_c8'] and $_POST['profile-information-grid_c10'] , and now is $_POST['profile-information-grid_c12'] and $_POST['profile-information-grid_c14'].
my problem is very involved. I cannot explain very good.
I want to have a fix id.
I donto why change id of check box?
Can I assign ids for checkboxs?
Can I assign ids for checkboxs? Sure, you better explicitly set checkbox column id:
'class' => 'CCheckBoxColumn', 'id'=>'column1', ... see these docs.
This way you firmly set it and you'll have no things like these yt0, yt2...
The same you can do for the buttons. See TButton docs.
Also you need to use double && in logical condition:
isset($_POST['profile-information-grid_c12']) & isset($_POST['yt1'])
I have a view helper that returns an array called $this->getTypes();
I've set it up as an invokable:
'view_helpers' => array(
'invokables' => array(
'getTypes' => 'Account\View\Helper\GetTypes',
),
),
If I echo it in the view can see the array, but in the form it fails.
I would like something like:
$this->add(array(
'name' => 'type_id',
'type' => 'Zend\Form\Element\Select',
'attributes' => array(
'required' => 'required',
),
'options' => array(
'label' => 'Type *',
'value_options' => $this->getTypes(),
),
));
Any ideas?
The short answer is: you don't
The medium answer is: to get DB-Values into your Zend\Form\Element\Select you have to inject your DB-/Service-Layer into your Form.
The long answer is: written in my Blog post Zend\Form\Element\Select and Database Values
I am trying to validate a multiply select using input filter, but every time I see a error. The error is "notInArray":"The input was not found in the haystack".(I use ajax but it doesn`t metter).
I will show part of my code to be more clear.
in Controller:
if ($request->isPost()) {
$post = $request->getPost();
$form = new \Settings\Form\AddUserForm($roles);//
$form->get('positions')
->setOptions(
array('value_options'=> $post['positions']));
//.... more code...
When I put print_r($post['positions']); I see:
array(0 => 118, 1 => 119)
in ..../form/UserForm.php I create the multiply element
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'attributes' => array(
'multiple' => 'multiple',
'id' => 'choosed_positions',
),
'required' => false,
'name' => 'positions',
));
and in the validation file the code is:
$inputFilter->add($factory->createInput(array(
'name' => 'positions',
'required' => false,
'validators' => array(
array(
'name' => 'InArray',
'options' => array(
'haystack' => array(118,119),
'messages' => array(
'notInArray' => 'Please select your position !'
),
),
),
),
What can be the reason every time to see this error, and how I can fix it?
By default selects have attached InArray validator in Zend Framework 2.
If you are adding new one - you will have two.
You should disable default one as follow:
$this->add(array(
'type' => 'Zend\Form\Element\Select',
'options' => array(
'disable_inarray_validator' => true, // <-- disable
),
'attributes' => array(
'multiple' => 'multiple',
'id' => 'choosed_positions',
),
'required' => false,
'name' => 'positions',
));
And you should get rid of the additional error message.
Please let us know if that would helped you.
Related to this post I want to transform a manual adding of a form element to Annotations in my Entity.
The code looks like this:
$this->add(array(
'name' => 'formElementName',
'type' => 'DoctrineModule\Form\Element\ObjectSelect',
'attributes' => array(
'required' => true
),
'options' => array(
'label' => 'formElementLabel',
'empty_option' => '--- choose formElementName ---',
'object_manager' => $this->getEntityManager(),
'target_class' => 'Mynamespace\Entity\Entityname',
'property' => 'nameOfEntityPropertyAsSelect'
)
));
As an annotation I have the problem that the object_manager is a variable which I cannot pass to annotations. Every other attribute is no problem and should work when being annotated.
I'm looking for the correct way to do this:
$form->get('formElementName').setOptions(array('object_manager'=>$entityManager)
Any ideas?
you have to try this it will working fine.
<!-- language-all: lang-html -->
foreach($cityArr as $city){
$city_ar[$city['id']] = $city['city'];
}
$form->user_city->setMultiOptions($city_ar);
$form->user_city->setValue($val["user_city"]);
